Air Source Heat Pumps In New York

New York’s proposed Community and Climate Protection Act has a goal for “the state of New York to reduce greenhouse gas emissions from all anthropogenic sources 100% over 1990 levels by the year 2050, with an incremental target of at least a 50 percent reduction in climate pollution by the year 2030”. In order to reach that ambitious CO2 reduction goal all sources of CO2 emissions have to be reduced. One energy sector with relatively large emissions is residential home heating and the clean energy alternative for home heating is electric heat pumps. In this post I explain why I think that air source heat pump deployment in New York coupled with the simultaneous goal to eliminate greenhouse gas emissions is fatally flawed based on a case study for conversions near Caledonia, NY.

Background

How Stuff Works explains that “heat pumps use a small amount of energy to move heat from one location to another”. Air conditioners cool our homes by removing heat from the air inside and moving outside. An air-source heat pump acts like an air conditioner in the summer and in the winter works in reverse moving heat from the outside air into the home to warm it. Obviously this kind of heat pump eliminates the need to have two separate systems and advocates tout its energy savings too. According to the Department of Energy (DOE):

An air-source heat pump can provide efficient heating and cooling for your home. When properly installed, an air-source heat pump can deliver one-and-a-half to three times more heat energy to a home than the electrical energy it consumes. This is possible because a heat pump moves heat rather than converting it from a fuel like combustion heating systems do.

Air-source heat pumps have been used for many years in nearly all parts of the United States, but until recently they have not been used in areas that experienced extended periods of subfreezing temperatures. However, in recent years, air-source heat pump technology has advanced so that it now offers a legitimate space heating alternative in colder regions.

For example, when entire units are replaced in the Northeast and Mid-Atlantic regions, the Northeast Energy Efficiency Partnerships (NEEP) found that the annual savings when using an air-source heat pump are around 3,000 kWh (or $459) when compared to electric resistance heaters, and 6,200 kWh (or $948) when compared to oil systems. When displacing oil (i.e., the oil system remains, but operates less frequently), the average annual savings are near 3,000 kWh (or about $300).

Reading this statement gives the impression that this technology is a “no regrets” solution for replacing oil heating CO2 emissions because it saves money for home heating. However, there is a critical caveat for New York State. Air-source heat pumps only work when they move heat and when it is really cold (below zero degrees Fahrenheit) there is no heat in the air to move.

The American Council for an Energy-Efficient Economy published a paper that illustrates this issue with air source heat pumps: Field Assessment of Cold Climate Air Source Heat Pumps (ccASHP) (https://aceee.org/files/proceedings/2016/data/papers/1_700.pdf). The report describes a Center for Energy and Environment field study in Minnesota where cold climate air source heat pumps were directly compared to propane and heating oil furnaces. The report notes that “During periods of very cold temperatures when ccASHPs do not have adequate capacity to meet heating load, a furnace or electric resistant heat can be used as backup.” Figure 2 (ASHP Supplemental Energy Use) from that document graphically shows the problem. In this field study homes were instrumented to measure the heat pump and furnace backup usage. Backup furnace usage was relatively low and the heat pump provided most of the heat until about 20 deg. F. For anything lower, heat pump use went down and the furnace backup went up. Below zero the air source heat pumps did not provide heat and furnace backup provided all the heat.

I believe that there are two problems with the plan to deploy air source heat pumps. I suspect but will not try to evaluate that because a fossil fired furnace or electric resistant heat must be used as backup in a typical New York State winter the cost savings from a more efficient heat pump are offset by the need to maintain a second heating system. The other problem is what might happen to peak electrical loads if electric resistant heat is the preferred backup system. The analyses that I have reviewed point out that converting a natural gas system to an electric heat pump system increases operating costs because natural gas is so low. Propane or fuel oil conversions save money so would be the first to convert because of the higher costs of propane and fuel oil. However, I am not sure that homeowners who convert would want to maintain an oil or propane furnace simply because of the storage system requirement. Consequently, I believe radiant electric heat will be the preferred option for air source heat pump conversions. If residential home heating is electrified significantly electric load will increase and I wonder what could happen to load when the efficient heat pump is replaced with radiant electric heat when the temperatures get really cold.

Procedure

I hypothesize that the combination of widespread air source heat pump deployment and increased reliance on wind and solar renewable energy will create unacceptable reliability issues during peak winter load periods. I evaluated energy usage for one week before and one week after the 2017-2018 peak winter day (January 5, 2018). I had previously analyzed data near Caledonia, NY and will use that for this analysis.

 I used two sources of data. Electric load data for New York State are available from the New York State Independent System Operator and meteorological data are available from the NYS Mesonet meteorological system. The NYS mesonet is a network of 126 weather observing sites across New York State. The official website of the Mesonet includes a tab for live data that brings up station information for the 125 operating individual sites that shows that available data include wind direction and speed, temperature at two levels, relative humidity, precipitation, pressure, solar radiation, snow depth, and camera images. I obtained hourly and 5-minute archived meteorological data for two sites near Caledonia, NY where a 180 MW solar farm has been proposed.

The Winter 2017-2018 load peak occurred during an intense cold snap. From December 29 to January 8 the temperature did not get above freezing and there were four days with below freezing temperatures as shown in the table of Daily temperature and load statistics. Note that the highest load did not occur on the coldest day. This was because the coldest day was a Saturday when business loads are lower. Also note that the New Year’s holiday occurred during this period which also reduced the load. The graph of load, temperature and wind speed for winter peak 2017-2018 shows how hourly load varies with temperature over the 15 day peak period.

In order to estimate how much renewable energy would be available during these conditions I converted to solar insolation and wind speed into power generated in MW using example utility-scale facilities. For solar power I used the 180 MW Horseshoe Solar Farm estimated output because it is near the NYS mesonet stations. In my analysis of Solar Issues in Upstate New York using that facility I assumed that 180 MW of power would be generated when the solar insolation equaled 600 watts per square meter and power output the rest of the time would be proportional so observed solar insolation. I believe that is a conservative assumption but would welcome comment.

There aren’t any wind farms nearby. So I estimated power output for a 100 MW wind farm. I found a reference that stated “Wind turbines start operating at wind speeds of 4 to 5 metres per second and reach maximum power output at around 15 metres/second”. I assumed that below 9 mi/hr wind output was zero and that power output was proportional to the wind speed difference between 9 mi/hr and 33 mi/hr consistent with that reference. The NYS mesonet measures wind at 10m and I assumed that the wind farm hub height was 90m. I modified observe wind speed using the wind profile power law with a coefficient of 1/7 to account for the relationship between wind speed and height.

I used Field Assessment of Cold Climate Air Source Heat Pumps Figure 2 (ASHP Supplemental Energy Use) to estimate the amount of power needed when an individual home convert to an air source heat pump and uses radiant electric heat when the heat pump becomes ineffective (assumed to be 15 deg F). I crudely digitized the lines in Figure 2 and calculated the best fit lines for ASHP Consumption and Furnace Backup Consumption. I converted the energy use to electrical energy by converting Btu to watts by dividing the Btu energy use by 3.41. The Energy Use for Residential Home Heating Electrification Table Table illustrates my concern that residential home heating conversion to air source heat pumps has the unintended consequence that when it gets below 15 deg F and consumers really need to heat their homes that the rate of energy use increases over six times per five degree drop in temperature.

Case Study

The purpose of this analysis is to determine if there are problems if the 100% renewable solar and wind target is coupled with widespread implementation of residential home heating with air source heat pumps. The Housing Units by Space Heating Fuel Table lists the number of occupied housing units for two counties near Caledonia. The Field Assessment of Cold Climate Air Source Heat Pumps report states that liquefied propane (LP gas) and fuel oil or kerosene space heating are the most likely sectors to convert to heat pumps because of fuel cost savings. There are 18,244 housing units that burn those two fuels. I calculated the electricity required for 10%, 15% and 25% conversions for 18,244 housing units.

The figure entitled Residential Home Heating ASHP Conversion and Renewable Power Case Study shows the relationship between home heat electrical load and meteorological conditions affecting renewable wind and solar power. Colder days in Upstate New York often occur on clear, windless nights. When the sun rises the temperature increases quickly. Although cloudless skies maximize solar power the sun is low in the sky and the days are short so the power output is low. Of course the cold weather increases the need for home heating energy.

The Cumulative Renewable Charging and Discharging Margins graph attempts to estimate energy storage requirements. Clearly the only way that solar and wind can be expected to cover winter peak loads is by incorporating energy storage. During this windless case study energy storage needs to discharge to cover the residential home heating power requirement as shown in blue. During the day solar power recharges the energy storage as shown in red. In this case study the maximum storage needed was 372 MW-hr on hour 82. It turns out that renewable excess power charged to the system before this case study was sufficient to cover that requirement.

Conclusion

This case study illustrates my concern that wide-spread implementation of air source heat pumps coupled with increased use of renewables will be difficult. In this analysis the meteorological conditions on New Year’s Eve 2018 show that the proposed Horseshoe solar facility with a nameplate capacity of 180 MW and a wind farm with a nameplate capacity of 100 MW would have been just able to cover the conversion of 2,737 homes to air source heat pumps. However, energy storage capable of at least 372 MW-hr has to be available somewhere. There already are 47,000 homes using electricity and another 15,000 homes that are supposed to be cost-effective candidates for conversion just in two local counties. Most importantly, this is just one component of residential electricity load which is one component of total load.

The Horseshoe Solar Farm – Public Involvement Program claims that the facility will provide enough electricity to meet the average annual consumption of 33,000 or 50,000 households, based on average annual household electric consumption of 10.8 MWh for the U.S. and 7.2 MWh for New York State, respectively. I bet that these household electric consumption averages do not reflect an electrically heated home in cold regions. If I guess that the average consumption for this 15 day period is a decent number for the heating season and assume a 90 day heating season that more than doubles the electric consumption for a New York State household. In other words there is no way Horseshoe Solar Farm is going to provide enough electricity for 50,000 homes using air source heat pumps.

Even though this is a crude “back of the envelope” analysis, the sobering results suggest that the Legislature should do a complete winter peak analysis correctly before codifying reductions that eliminate fossil fueled power plants and require the conversion of residential home heating to meet some arbitrary CO2 reduction goal. According to Patterns and Trends – New York State Energy Profiles: 2002-2016 there are over a million homes currently using fuel oil or kerosene, 500,000 homes using electricity and another 200,000 using propane in New York State.

Based on my analysis I think that even moderate air source heat pump deployment for the residential home heating sector in New York coupled with the simultaneous goal to eliminate greenhouse gas emissions using extensive deployment of wind and solar power is fatally flawed.  I cannot imagine how much wind power, solar power and energy storage would have to be deployed to cover the winter peak, much less the winter peak adding significant electrification of residential home heating, for the entire state because those renewable resources are very weak during winter peak load periods. It is incumbent upon the advocates for the Climate and Community Protection Act to determine what renewable resources will be required and how much they will cost before their legislation is considered by the Legislature.

 

Solar Energy Issues in Upstate New York

Led by Governor Andrew Cuomo, New York’s solar ambitions are a key component in his agenda for to ensure “vital progress on the climate” is continued. This is a post on one aspect of the NY-Sun program. I am a retired meteorologist who worked in the electric generation sector for over 35 years and I know that New York is not a particularly sunny place in the winter so I wanted to check out potential issues with solar variability during the peak summer and winter loads. The opinions expressed in this post reflect my personal opinion.

Introduction

NY-Sun is supposed to make solar affordable for all New Yorkers. According to the NY Sun section in the NYS website Leading on Climate Change and Protecting our Environment:

  • NY-Sun is developing a sustainable, self-sufficient solar industry in the State by incentivizing New Yorkers, businesses, and communities to invest in solar energy.
  • The Governor’s $1 billion NY-Sun program has grown solar power in New York State by nearly 800% since 2011, and has reduced greenhouse gas emissions by nearly 25%.
  • The program aims to add more than 3 gigawatts of installed solar capacity in the State by 2023, enough solar energy to power 400,000 homes.

(Proof reading this before publication I was struck by these claims so I posted on them at my companion site.)

In order to evaluate the effect of solar variability on the transmission grid I needed an example facility. New York State’s permitting process for power plants of 25 megawatts or higher has extensive requirements for public involvement. Invenergy Solar Project Development LLC has started the permitting process for construction of Horseshoe Solar Farm which I will use as my example. According to the Horseshoe Solar Farm – Public Involvemen Program it will be a 180 MW Solar Electric Generating Facility Located in the Town of Caledonia, Livingston County, New York. Eventually I will address this particular project in detail later but this post only looks at potential performance during peak periods.

It is interesting to note that the New York Independent System Operator had this to say about solar photo voltaic (PV) facilities in their 2018 Load & Capacity Data report:

The actual impact of solar PV varies considerably by hour of day. The hour of the actual NYCA peak varies yearly. The forecast of solar PV-related reductions in summer peak reported in Table I-9 assumes that the NYCA peak occurs from 4 p.m. to 5 p.m. EDT in late July. The forecast of solar PV-related reductions in winter peak is zero because the sun sets before the assumed peak hour of 6 p.m. EST.

Because reliability planning necessarily focuses on peak periods I decided to look at the loads on the 2017 peak summer day (July 19, 2017) and the 2017-2018 peak winter day (January 5, 2018). The load data are available from the NYISO on hourly or 5-minute intervals. I decided to estimate the capacity from this facility during these peak periods (one week before and one week after the peak day) using the hourly data. I also wondered about the short term variations so I used the five minute data for the 72 hours around each peak day.

Analysis

In order to estimate the solar generation output from this facility I used solar radiation data from two nearby NYS Mesonet meteorological systems (Rush and York). The NYS mesonet is a network of 126 weather observing sites across New York State. The official website of the Mesonet includes a tab for live data that brings up station information for the 125 operating individual sites. You can change the station by clicking on any dot on the state map. Data available include wind direction and speed, temperature at two levels, relative humidity, precipitation, pressure, solar radiation, snow depth, and camera images. I got archived solar insolation data on an hourly and 5-minute interval for two nearby sites that I used to estimate solar generation.

I calculated the electrical generation output from the 180 MW Horseshoe Solar Farm based on my internet research. I think it is a pretty good estimate but if someone reading this could confirm that or tell me what I am doing wrong I would appreciate it. The mesonet stations provide solar insolation measured in watts per meter squared. I assumed that the 180 MW of solar cells produced 180 MW when the solar insolation equals 800 watts per square meter (the PVUSA test condition) and I did not account for any other factors such as the cell temperature or any losses. So my naïve formula was simply the observed input solar insolation times 180 divided by 800.

The first question to address is how much power can we expect from a 180 MW facility in upstate New York during the peak periods? Frankly, I would expect this location to be pretty good relative to other central to western New York sites. Locations closer to Syracuse would be worse and locations due east of Lake Erie or Lake Ontario would be much worse because of lake-effect clouds. The Estimated Solar Generation from Horseshoe Solar Farm table lists the results. In the summer the results are pretty good. According to my methodology peak output could be over 200 MW when insolation is highest and the capacity factor over the entire 15-day peak period is over 23%. However, in the winter the solar generation output would be abysmal. The peak generation hour was only 103 MW and the capacity factor of the 15-day peak period would be no more than 7%.

The second question is what about the shorter term variability in solar generation output. The Genesee Load and Horseshoe Solar figure lists 5-minute load (MW) data for the Genesee Control Area Total Load (pink circles), estimated Horseshoe solar potential output using the Rush NYS Mesonet station solar radiation data (blue box) and the estimated Horseshoe solar potential output using the York NYS Mesonet station solar radiation data (red cross).

There are several issues. Note that the scales are different so for starters this solar farm makes little difference to the energy needs of the Genesee NYISO control area load.  As noted by NYISO the solar potential energy diurnal cycle does not match the load peak well because actual load peaks after solar generation peaks. The estimates of solar generation from both sites shows quite a bit of variation during the day. For example, the peak insolation at 12:55 EDT is 1,046 watts per square meter but ten minutes later it is down to 491. I estimate that will translate into a swing of over 100 MW that some facility somewhere has to cover. Also note that there are numerous periods when the estimated solar generation using Rush data differ from estimates using York data. This suggests that it was a partly cloudy day with significant variations in solar insolation. Because these are 5-minute averages the instantaneous variations are likely larger.

Ramifications

As I suspected these data show that the proposed NY-Sun solar buildout in Upstate New York will not end well. With respect to the abysmal capacity factor of the winter peak keep in mind that Cuomo’s Reforming the Energy Vision includes plans to convert residential home heating to electrical heating and there are activists that not only want to do that on an accelerated schedule but also are insisting that all the electrical power be produced by wind and solar energy only. Theoretically, battery storage could provide all the renewable power. However, only the energy innumerate or energy naïve could possibly think that solar energy coupled with battery storage could provide enough energy to heat all upstate residences during winter peak periods without massive overbuilding of both solar farms and battery storage simply because solar potential in the winter is so poor.

The summer short-term period data illustrate the fallacy that solar is cost-equivalent to coal or gas or whatever the claim is today. Fossil-fired facilities provide near constant energy but these data show that solar has huge variations. When considered alone, if this facility or any other solar facility gets built someone else on the grid has to provide support so that power sent to the grid is near constant. Battery energy storage can provide that service and frankly given the degree of intermittency on a day like the peak summer day would be the only solution that might work. However, any battery solution at least doubles the cost of solar. Not surprisingly it is even worse. If you dedicate a battery array to providing smooth power you cannot use the battery array for storage. The State really needs to explain how they propose to incorporate 3 gigawatts of solar.

On the other hand, if battery storage is a requirement for a solar facility these impacts are addressed. That way their wildly fluctuating output does not impact the grid and the units can be dispatched to match the observed load. Of course if that is required the price of solar at least doubles so it is unlikely that prudent and politically inconvenient approach will be adopted.

NYS Energy Profile Patterns and Trends

On March 1, 2019 the New York State Energy Research & Development Authority (NYSERDA) Energy Analysis program published Patterns and Trends – New York State Energy Profiles: 2002-2016 which they described as a “comprehensive storehouse of energy statistics and data on energy consumption, supply sources, and price and expenditure information for New York State.”   I agree and strongly recommend that anyone who has any interest in New York State energy download the document and check it out.

For numbers geeks like me one of the features that I really love is the fact that the tables are linked to spreadsheets. For example, Table 3-1b: NYS Primary Consumption of Energy by Sector in the report only lists data from 2002 to 2016 but when you click on the table and download the spreadsheet data back to 1980 are available. Moreover, the data are in a spreadsheet so you can process it as you wish.

It is very disappointing that there was a 26 month lag between the end of the report period and the publication of the data. I consider this one of the best products of NYSERDA but apparently under the rule of the Cuomo Administration it is not a priority. Before the Cuomo Administration this report came out 13 months after the end of the reporting period. The 1997-2011 report was 18 months later and the last three reports were dated in October so were 22 months late.

I will be using these data in future posts but I cannot help but show how useful it is in one example. National Grid’s “Northeast 80×50 Pathway” is a blueprint for the region to reduce its greenhouse gas emissions 80 percent below 1990 levels by 2050 (“80×50”). The first of its kind in the Northeast, the Pathway spans seven states (New York and the six New England states), and addresses the three main sectors of emissions: transportation, electricity, and heat. If you search on “National Grid Northeast 80 by 50 Pathway” you will get a list of fawning articles talking about how great this is but I am a customer worried about home heating and they are talking about a plan for that.

The politically correct approach for reducing emissions from home heating is to convert to heat pumps. According to the pathway:

Heat pumps are very different from standard electric resistance heaters. Compared to traditional “baseboard” technologies, heat pumps achieve a 50-80% reduction in electricity use by moving heat rather than creating it. They use conventional refrigeration technology to absorb heat from one source (air, ground, or water), transfer it to another source, and raise it or lower it to a temperature suitable for space heating (or cooling) and hot water. Heat pumps still face major adoption challenges. In particular, ground-source heat pumps need to achieve cost declines to become more accessible to customers, and air-source heat pumps need to be paired with proper building insulation.

The question is just how much energy are we talking about. The Patterns and Trends document includes a table of NYS Net Residential Consumption of Energy by Fuel Type that shows just ambitious changes to home heating will be. Total residential consumption of energy typically totals 800 TBtu or 800 trillion British thermal units. Thomas Fuller writing about the challenges of meeting the Green New Deal notes that a BTU is a unit of energy–strictly speaking the energy required to raise the temperature of a pint of water from 39 to 40 degrees Fahrenheit. About the amount of energy released from a burning wooden match. There are around 115,000 BTU per gallon of gasoline and one TBtu is equivalent to 39,000 cars driving round trip between New York and Los Angeles if the cars get 25 miles per gallon.

I graphed the data to see the NYS Residential Energy Consumption trends. Natural gas use has increased over time, coal has disappeared and petroleum products have decreased.  Today Natural gas provides 58% of the home heating energy, petroleum products 16%, and wood around 2%. Electricity, solar and geothermal provide 24%. National Grid’s pathway suggests that petroleum product heating should be converted to electricity which would mean that 128 TBtu of energy needs to be replaced. While that seems plenty ambitious to me there are those that think that we need to convert all home heating to electricity, solar and geothermal. I think that the disruption and expense of complete conversion far out-weighs any benefits but that will be the subject of another post.

NY Green New Deal – NYS 2010 Climate Action Plan

This is one of a series of posts on Governor Andrew M. Cuomo’s New York State Green New Deal. The announcement noted that it will create the State’s first statutory Climate Action Council, comprised of the heads of relevant state agencies and other workforce, environmental justice, and clean energy experts to develop a plan to make New York carbon neutral.  Not mentioned was the fact that there was a previous Climate Action Council that was not created by statute. This post will highlight the draft plan produced by the first Climate Action Council in late 2010.

According to the New York State Department of Environmental Conservation (DEC):

Executive Order No. 24 set a goal to reduce greenhouse gas (GHG) emissions in New York State by 80 percent below the levels emitted in 1990 by the year 2050. The Executive Order also created the New York State Climate Action Council (CAC) with a directive to prepare a climate action plan. The climate action plan would assess how all economic sectors can reduce greenhouse gas emissions and adapt to climate change. The Plan would also identify the extent to which such actions support New York’s goals for a clean-energy economy.

On November 9, 2010, the CAC released an Interim Report that had been prepared with assistance from the New York State Energy Research and Development Authority (NYSERDA), the Department of Environmental Conservation (DEC), and other CAC member-agency staff, the Center for Climate Strategies (CCS) and other stakeholders. This Interim Report is presented by sections and chapters at the DEC website.

First Climate Action Council Plan

For my purposes, Chapter 4: Envisioning a Low-Carbon Future is of most interest. This effort is based in large part upon a Brookhaven National Lab white paper entitled Envisioning a Low-Carbon Clean Energy Economy in New York. The ultimate question is whether the earlier New York State 80 by 50 goal is feasible not only based on cost but on technical considerations. I had originally intended to dissect this vision of the future to address those points but I think the following Important Note to Readers from the white paper speaks to my concerns. I have highlighted the critical point.

Important note to readers:

This is the first complete draft of a paper designed to inform the NYS Climate Action Council’s work to develop a State Climate Action Plan.

The Council’s mandate is uncommonly broad in scope. It has a planning horizon far longer than what most planners address. It entails large uncertainties. No clear precedent for an enterprise of this scope exists.

Consequently, this draft paper is necessarily provisional. As the planning process proceeds, the paper will be revised, and it will steadily gain in value as fresh insights are acquired and the knowledge base it draws from expands.

One feature of this paper is a description of three scenarios that illustrate different versions of a low-carbon 2050 future for the state. It’s important that readers understand that these scenarios are offered for illustrative purposes only. In no sense do they constitute the elements of a plan, and indeed even a casual review of them reveals that there is no way in which they could be fashioned into a plan. Rather, they’re intended to facilitate and provoke thinking about the future.

We hope other parties will generate their own 80×50 scenarios and share them. The ability to imagine a sustainable future, model it rigorously, and explore it is as vital to achieving that future as the clean-energy technologies, best management practices, and behavioral changes that must be developed, advanced, and adopted.

Conclusion

The Brookhaven White Paper developed three future scenarios. One scenario expanded on existing programs to make the most obvious emission reductions. Although it assumed “significant changes to current practices, this scenario falls far short of achieving 80 percent emissions reduction by 2050.” The second scenario assumed electrification of the entire light-duty vehicle fleet to hydrogen fuel produced with nuclear or other low-carbon electricity, elimination of fossil fuel combustion in the residential, commercial, and industrial sectors and significant use of locally-sourced biofuels for trucks and aircraft but was only able to make a 79% reduction. In order to get to an 80% reduction the final scenario assumes 95% of all vehicle miles are all-electric miles, eliminates fossil fuel combustion in the residential/commercial/industrial sector with “part of the resultant increase in electricity demand met through local, point-of-use solar and much of the remainder with low-carbon generation and the wide-spread use of carbon-capture and sequestration”.

It does not take much effort to come to the same conclusion as Brookhaven that there is no way that these scenarios could be fashioned into a plan. Ultimately, the question is whether there is any possible plan to meet the ambitious goals of New York’s Green New Deal.

NY Green Deal: Mandate 100 Percent Clean Power by 2040

This is one of a series of posts on Governor Andrew M. Cuomo’s New York State Green New Deal. As part of his 2019 Justice Agenda he included a “nation-leading clean energy and jobs agenda that will put the state on a path to carbon neutrality across all sectors of New York’s economy”.

Not surprisingly there are no details other than the announcement, no mention of potential costs, and no explanation how all this will affect any of the many impacts that he claims are caused by climate change. There is a proposal to provide the plan to make New York carbon neutral and I will blog on those plans as they become available. In the meantime this post discusses the language used to describe the proposal to mandate 100 percent clean power by 2040 in the New York Green New Deal.

In the following sections I list the text from the announcement and my indented and italicized comments follow.

As part of the Green New Deal, Governor Cuomo is proposing a mandate of 100 percent clean, carbon-free electricity in New York State by 2040, the most aggressive goal in the United States and five years sooner than the target recently adopted by California. The cornerstone of this new goal is an increase of New York’s successful Clean Energy Standard mandate from 50 percent to 70 percent renewable electricity by 2030. This globally unprecedented ramp-up of renewable energy will include:

Quadrupling New York’s offshore wind target to 9,000 megawatts by 2035, up from 2,400 megawatts by 2030

I addressed the offshore wind target in a different post.

Doubling distributed solar deployment to 6,000 megawatts by 2025, up from 3,000 megawatts by 2023

As a meteorologist I fail to see how solar this far north and in a climatic regime with as many clouds and as much snow as New York in general and near the Great Lakes in particular makes much sense. Furthermore a study by Ferroni & Hopkirk 2016 shows that after 25 years, solar panel farms in Germany & Switzerland produced only 82% of the energy required to manufacture, install, & maintain them. It also demonstrated that at this point in time (at current solar panel efficiency) latitude 35N (approximately the southern border Tennessee) is the solar energy break even line. After 25 years of operation, solar farms north of this line produce LESS energy than it takes to manufacture, install, & maintain them, while solar farms south of this line produce more. There is more discussion of this analysis and its conclusions here. In any event, I believe that adherents for the New York Green New Deal should explain how solar in New York is immune to these issues.

More than doubling new large-scale land-based wind and solar resources through the Clean Energy Standard

I hope that the State eventually provides a roadmap that quantifies which resources get which subsidies under which programs but I am not optimistic.

Maximizing the contributions and potential of New York’s existing renewable resources

I support this platitude but hope that this was part of the plan all along.

Deploying 3,000 megawatts of energy storage by 2030

None of the announcements for energy storage have included the amount of energy in MWh in their goals. Instead they always use MW or the power capacity to describe the projects. Because the amount of energy is the key parameter this suggests energy innumeracy on the part of the State’s politicians. I also note that I agree with those that believe that grid storage is impossible.

Achieving 100 percent carbon-free electricity will require investments in resources capable of meeting diverse demands throughout the state, as well as a substantial increase in cost-effective energy efficiency. Harnessing a complementary set of carbon-free energy resources will assure reliability and affordability for all New Yorkers as the electricity system is both modernized and optimized. To ensure that clean energy opportunities are available for those that need it most, as part of this nation-leading commitment, Governor Cuomo is directing the New York State Energy Research and Development Authority (NYSERDA), in concert with the Department of Public Service (DPS), to expand and enhance their Solar For All program and couple it with energy savings opportunities, increasing access to affordable and clean energy for low-income, environmental justice and other underserved communities.

I am not confident that renewables can ever supply enough energy to New York City to maintain reliability. Given that a blackout in the City is a bad thing this could be a fatal flaw. Consider that in order to prevent the situation that caused the 1977 New York City the New York Independent System Operator currently requires at least 80% of New York City’s electric generating capacity needs be met through in-City generation. The problem is that diffuse renewable generation needs space which is at a premium in the City. The State needs to show how they can possibly provide enough carbon-free electricity to cover peak generation. On the peak hour of generation in 2017 the load in the New York City zone was 10,671 MW. If the City were to rely on solar power to provide the load from the time that solar power added to the system until the next day you would need (219,078 MWh) and 80% of the total load would have to come from in-City or 175,262 MWh. I did a back of the envelope estimate of the solar and storage necessary to cover this peak in Table 1 New York City peak load generation with solar and storage. I used a solar hourly distribution curve for California in July which should be conservative to estimate hourly variation. I estimated the amount of solar needed by subtracting the daily solar output energy in MWh (daily sum of the Generation column) against 80% of the actual NYC load (the Limit column). I took a naïve approach and determined the necessary solar generation as the level that would eliminate any negative value in the Difference column. On the peak day there was a minimum positive difference of 10 MWh at hour 6 when the system would still rely on storage to provide power and determined that if there were 26,045 MW of solar capacity the needs could be met. That is a low estimate because there is no provision for clouds, battery charging times or charging efficiencies. Nonetheless, using a rule of thumb that 1kW needs 100 square feet of space that estimated capacity would need 629 square miles which is more than double the size of New York City.

This crude analysis is only meant to serve as an indication just how work has to be done to develop this plan. I think that the Governor and advocates for his agenda need to explain how this will work, how much it will cost and how much it will affect global warming before we are committed to this path.

 

NY Green Deal: Create a Carbon-to-Value Innovation Agenda

This is one of a series of posts on Governor Andrew M. Cuomo’s New York State Green New Deal. As part of his 2019 Justice Agenda he included a “nation-leading clean energy and jobs agenda that will put the state on a path to carbon neutrality across all sectors of New York’s economy”.

Not surprisingly there are no details other than the announcement, no mention of potential costs, and no explanation how all this will affect any of the many impacts that he claims are caused by climate change. There is a proposal to provide the plan to make New York carbon neutral and I will blog on those plans as they become available. In the meantime this post discusses the language used to describe the plan to create a carbon-to-value innovation agenda as part of the New York Green New Deal.

In the following sections I list the text from the announcement and my indented and italicized comments follow.

Create a Carbon-to-Value Innovation Agenda and Establish the CarbonWorks Foundry

Avoiding the worst consequences of climate change will require not only reductions in emissions using existing technologies, but also innovation, particularly with respect to withdrawing CO2 from the Earth’s atmosphere. Innovative new technologies are emerging in response to this challenge that can capture CO2 from the atmosphere and either permanently sequester the carbon underground or transform it into valuable fuel or products, known as carbon-to-value. While many of these technologies are still in their infancy, they show promise in the collective fight to address climate change.

The concept is to turn carbon dioxide into fuel and wasteful chemicals. While I am not a chemical engineer the idea that the waste products can be turned into a fuel without a whole lot of energy going back into the system seems a bit far-fetched. On the other hand the concept of using CO2 instead of sequestering it underground is appealing.

Accordingly, Governor Cuomo is announcing that in 2019, New York State, with the help of experts, environmental groups, academic institutions, and other stakeholders will create a Carbon-to-Value Innovation Agenda as a blueprint for the future of carbon-to-value technology as well as carbon capture, utilization and storage in New York. NYSERDA will provide $15 million to support multiple efforts to further New York’s Carbon-to-Value Innovation Agenda. This will include NYSERDA and SUNY working with academic institutions, experts, and philanthropic partners to establish the CarbonWorks Foundry, a new incubator and accelerator devoted to carbon-to-value technology development with a focus on carbon harvesting. Finally, NYSERDA will engage other State agencies to create a framework for a low-carbon procurement standard, which can create a market for low-carbon cement and concrete, building materials, and other valuable low-emissions products.

For these types of blueprints I would be more supportive if they included provisions to make sure that the Foundry would terminate if certain criteria are not met. If it is promising great but if it is not then accept that we found out that the concept while promising in theory was not practical. If any of these ideas go forward they should include metrics and regular reporting.

NY Green Deal: Increase Carbon Sequestration

This is one of a series of posts on Governor Andrew M. Cuomo’s New York State Green New Deal. As part of his 2019 Justice Agenda he included a “nation-leading clean energy and jobs agenda that will put the state on a path to carbon neutrality across all sectors of New York’s economy”.

Not surprisingly there are no details other than the announcement, no mention of potential costs, and no explanation how all this will affect any of the many impacts that he claims are caused by climate change. There is a proposal to provide the plan to make New York carbon neutral and I will blog on those plans as they become available. In the meantime this post discusses the language used to describe the plan to increase carbon sequestration and meet a land challenge as part of the New York Green New Deal.

In the following sections I list the text from the announcement with my indented and italicized comments.

Increase Carbon Sequestration and Meet the U.S. Climate Alliance Natural and Working Lands Challenge

In 2015, Governor Cuomo launched the Climate Resilient Farming Program to reduce greenhouse gas emissions from agriculture and to increase resiliency of New York State farms impacted by climate change. Just last year, New York accepted the U.S. Climate Alliance’s Natural and Working Lands challenge, ensuring that land stewardship and land sequestration efforts join energy reduction and adaptation activities as part of our collective climate solutions.

According to the New York Soil & Water Conservation Committee website “The goal of the Climate Resilient Farming Program is to reduce the impact of agriculture on climate change (mitigation) and to increase the resiliency of New York State farms in the face of a changing climate (adaptation).” The plan is to mitigate and adapt.

Estimates of annual greenhouse gas emissions from agriculture (apart from agricultural energy use, which is classified differently) in New York State range from 5.3 to 5.4 million metric tons of carbon dioxide equivalent. Manure management is responsible for roughly 15% of the emissions; emissions from soils are slightly under a third of the total. This represents a major opportunity to reduce emissions.

 While New York State is projected to increase precipitation overall, it is expected to come in short, extreme precipitation events in between mild droughts. This represents a major risk to farms, particularly those in low-lying or flood prone areas. Even very local downpours and cloud bursts can cause substantial damage to farms.

On the face of it this program is innocuous but is it effective? According to the most recent press release I could find: Governor Andrew M. Cuomo today announced nearly $2.2 million will be awarded to 34 farms across the state through the Climate Resilient Farming Grant Program. Launched by the Governor in 2015, the program helps farms reduce their operational impact on the environment and better prepare for and recover after extreme weather events. Through three rounds of funding to date, the state has provided $5.1 million to 40 total projects, assisting nearly 70 farms. I have included a description of the awards made for 2018 at the end of the post. My biggest problem is that the 34 farms received money from the state for projects that in some cases seem like business as usual practices. Unless a program can provide this kind of support to every farm in the state then where are we going with this? If my neighbor gets money to do a project why in the world would I do it, however appropriate for the environment, unless I get money too?

To meet our Natural and Working Lands commitment, Governor Cuomo will establish new research partnerships to incorporate forest and agricultural carbon into New York’s greenhouse gas inventory and climate strategy and to establish a carbon sequestration goal for our natural and working lands. To help achieve this goal, Governor Cuomo proposes doubling the State’s investment in the Climate Resilient Farming program and creating new forestry grant programs—enhancing the Healthy Soils NY program and enabling farmers, forest owners, and communities to achieve the economic and environmental co-benefits of sound management practices.

I think the concept that increasing the carbon content of the soil is a no regrets solution. The basic concept is that building healthy soil sequesters carbon dioxide. My point is that healthy soil is good for the planet whatever the effect of CO2 on climate. As mentioned above, however, I think the New York program has to take the big picture approach how to implement their plan across all the farms and forests rather than awarding grants to the politically connected.

Awarded Projects Climate Resilient Farming Grant Program April 27, 2018

  • Fulton County Soil and Water Conservation District was awarded $74,494 to assist one farm with the implementation of a 45-acre prescribed grazing and 5.7-acre riparian buffer system that will increase soil health and reduce farm based greenhouse gas emissions.
  • Herkimer County Soil and Water Conservation District was awarded $432,659 to work with a dairy farm to install a manure storage cover and flare. The system will dramatically reduce methane emissions from the farm’s manure storage, mitigate water quality concerns – especially during major precipitation events, and promote energy savings.

NY Green Deal: Investments in the Clean Tech Economy

This is one of a series of posts on Governor Andrew M. Cuomo’s New York State Green New Deal. As part of his 2019 Justice Agenda he included a “nation-leading clean energy and jobs agenda that will put the state on a path to carbon neutrality across all sectors of New York’s economy”.

There is a proposal to provide the plan to make New York carbon neutral and I will blog on those plans as they become available. In the meantime this post discusses the language used to describe the multi-billion dollar price tag of the New York Green New Deal.

In the following sections I list the text from the announcement and my indented and italicized comments follow.

Demonstrating New York’s real-time commitment to implementing the most ambitious clean energy agenda in the United States, Governor Cuomo is also announcing $1.5 billion in competitive awards to support 20 large-scale solar, wind, and energy storage projects across upstate New York. These projects will drive a total of $4 billion in direct investment in New York’s growing clean energy economy, as well as add over 1,650 megawatts of capacity and generate over 3,800,000 megawatt-hours of renewable energy annually – enough to power nearly 550,000 homes and create over 2,600 short-term and long-term jobs. Once all permitting and local requirements are met, several projects are expected to break ground as early as August 2019 and all projects are expected to be operational by 2022. The projects will reduce carbon emissions by more than 2 million metric tons, equivalent to taking nearly 437,000 cars off the road. Combined with the renewable energy projects previously announced under the Clean Energy Standard, New York has now awarded more than $2.9 billion to 46 projects, accelerating New York’s progress and commitment to Governor Cuomo’s Green New Deal.

The New York State Energy Research and Development Authority (NYSERDA) described the 20 large-scale projects in a press release. Table 1 green new deal clean energy project investments lists the projects and provides some details. There are 1,040 MW of solar at 16 sites and 613.7 MW of wind at 4 sites with a total of 45 MW of energy storage included at three facilities.

New York State has extensive electric facility siting requirements for any project of 25 MW or greater. Article Ten is supposed to provide a common framework for siting generation facilities in a streamlined permitting process. There are specific requirements for environmental and public health analyses. However, this process is time consuming and costly. While there are timing requirements for agency responses, nonetheless in my opinion it is practically impossible to meet all the requirements in less than five years. Of the 1654 MW in the announced projects, there is one small 4.99 MW project and eight 19.99 MW capacity projects (159.92 MW total) that are exempt from the Article Ten requirements. Of the remaining 11 projects, there are four projects totaling 462.69 MW that have not submitted anything to the Article Ten Siting Board, four projects totaling 499 MW that have completed the first step by submitting Public Involvement Programs, two projects totaling 237.5 MW have completed the second step by submitting their preliminary scoping plans and one 290 MW project has reached the third step submitting their application.

 The competitive awards total $1.5 billion and are supposed to provide more than 2 million tons of carbon reductions. Assuming that they really meant carbon dioxide for the 2 million tons that means 750 dollars per ton reduction cost. In 2015 NYS electric sector CO2 emissions were 32 million tons. If the New York Green New Deal were to rely on the NYSERDA competitive award process for those reductions the State is looking at a staggering cost of $24 billion.

NY Green Deal: Justice, Transition and Clean Energy Jobs

This is one of a series of posts on Governor Andrew M. Cuomo’s New York State Green New Deal. As part of his 2019 Justice Agenda he included a “nation-leading clean energy and jobs agenda that will put the state on a path to carbon neutrality across all sectors of New York’s economy”.

Not surprisingly there are no details other than the announcement, no mention of potential costs, and no explanation how all this will affect any of the many impacts that he claims are caused by climate change. There is a proposal to provide the plan to make New York carbon neutral and I will blog on those plans as they become available. In the meantime this post discusses the language used to describe the plan to deliver climate justice, reduce impacts of the transition, and develop a clean tech workforce as part of the New York Green New Deal.

I have combined three proposals in this post because they are all out of my energy and environmental analysis background. Bluntly, all three seem to be political favors incorporated to curry favor from three groups to support the Green New Deal. None of them will have any impact on emissions reductions or energy transition. In the following sections I list the text from the announcement and my indented and italicized comments follow.

Proposal. Deliver Climate Justice for Underserved Communities

In 2016, the Governor introduced an ambitious environmental justice framework, establishing a statewide commitment to addressing the historic disparate environmental burdens suffered by communities of color and low-income communities. In 2017, he introduced an Environmental Justice and Just Transition Working Group to ensure that environmental justice and a just transition of New York’s workforce are an integral part of New York’s clean energy and climate agenda. In the past 3 years, New York State has invested more than $16 million through the Environmental Protection Fund in environmental justice initiatives. New York also currently has over 151,000 individuals employed by clean energy industries throughout the state and has committed $70 million in workforce training in the clean energy economy. As part of the Green New Deal, Governor Cuomo will build upon these important foundations for making environmental justice and just transition central to moving to a carbon neutral economy.

On June 2, 2017 Cuomo established an environmental justice & just transition working group to help historically underserved communities prepare for a clean energy future and adapt to climate change. The announcement said the working group “will focus, in part, on developing policies and programs to ensure a ‘just transition’ to a green and clean energy future.” The announcement included a list of members and said that it would “advise the administration on the integration of environmental justice and just transition principles into all agency policies, and to shape environmental justice programs identified in State of the State and inform what work products would assist in this effort. The first Working Group session will convene in June.” However, I have been unable to find any references to this group since then.

 The announcement notes New York State has invested more than $16 million through the Environmental Protection Fund (EPF) for environmental justice initiatives. A Financial History of the fund notes that:

This fund is supposed to provide a source of funding for capital projects that protect the environment and enhance communities. EPF appropriations have totaled $3.4 billion from its creation in 1993 through the State’s last complete fiscal year, 2016-17. Of this, some $2.6 billion had been spent on environmental protection, parks and other related programs as of March 31, 2017. Over the life of the Fund, more than $953 million in EPF resources has been diverted to the General Fund for budget relief. While some of this was replaced with borrowed funds, over half, or $507.2 million, has not been replenished.

While that report also notes that EPF resources for environmental justice grants help residents in areas suffering from systemic neglect and legacy pollution to rebuild healthier communities it also notes that DEC does not provide annual, comprehensive assessments of the status and needs supported by the EPF. In light of the Comptroller’s report I could not check how the money was spent.

 The Green New Deal will help historically underserved communities prepare for a clean energy future and adapt to climate change by codifying the Environmental Justice and Just Transition Working Group into law and incorporating it into the planning process for the Green New Deal’s transition. To increase the effect of funds and initiatives that target energy affordability, the Governor is directing the State’s low-income energy task force to identify reforms to achieve greater impact of the public energy funds expended each year. The Governor is also directing each of the State’s ten Regional Economic Development Councils to develop an environmental justice strategy for their region.

Presumably once the Environmental Justice and Just Transition Working Group is codified into law they will actually meet regularly. New York State has a terrible record spending climate reduction funds where they are supposed to be spent rather than on politically expedient pork but we will see if this program is different.

New York State currently directs more than $700 million in ratepayer and federal funds each year to combat energy poverty and increase access to clean energy solutions for the 2.3 million low-income households in the state. However, current programs only reach 1.4 million households each year with bill assistance programs, and less than 20,000 households each year with clean energy measures.

As part of the Green New Deal, Governor Cuomo will address energy poverty in New York State by directing the low-income energy task force, comprised of NYSERDA, DPS, OTDA, and HCR, to develop a roadmap and unified strategy to increase the impact of funds and initiatives that target energy affordability. Specifically, the Governor is directing the task force to assess policy, programmatic, and administrative reforms necessary to achieve greater impact of public funds expended each year.

In my opinion the primary goal of the task force should be to keep electric energy affordable. I am encouraged that the announcement recognizes the importance of energy poverty. However, I will only be satisfied when the State establishes an energy poverty metric and tracks it throughout the transition.

 Proposal. Create a Fund to Help Communities Impacted by the Transition Dirty Power

Governor Cuomo is introducing legislation to provide funding to help communities that are directly affected by the transition away from conventional energy industries and toward the new clean energy economy. Specifically, this funding will protect communities impacted by the retirement of conventional power generation facilities. The Governor is also calling upon the Environmental and Just Transition Working Group to contribute to and advise on the development of a Just Transition Roadmap for the Green New Deal.

In my opinion this is an example of the political pandering of the Green New deal. If New York does implement this plan all the municipalities that have depended on a fossil-fired power plant for jobs and taxes for many years will be scrambling to find a replacement industry. One of the subsidies commonly provided to renewable facilities is a pilot (or payment in lieu of taxes) agreement. It would be interesting to determine if the tax benefits of the Green New deal will replace the taxes generated by the legacy fossil plants.

Proposal. Develop Clean Tech Workforce and Protect Labor Rights

To ensure creation of high-quality clean energy jobs, large-scale renewable energy projects supported by the Green New Deal will continue to require prevailing wage, and the State’s offshore wind projects will be supported by a requirement for a Project Labor Agreement. To prepare New York’s workforce for the transition, New York State will take new steps to support workforce development, including establishing a New York State Advisory Council on Offshore Wind Economic and Workforce Development, as well as investing in an offshore wind training center that will provide New Yorkers with the skills and safety training required to construct this clean energy technology in New York.

In my opinion this is another example of the political pandering of the Green New Deal. This has all the signs of a progressive politician appealing to his political base. How this will reduce emissions and save the planet from global warming is unclear.

 

NY Green Deal: Effect on Global Warming

This is one of a series of posts on Governor Andrew M. Cuomo’s New York State Green New Deal. As part of his 2019 Justice Agenda he included a “nation-leading clean energy and jobs agenda that will put the state on a path to carbon neutrality across all sectors of New York’s economy”.

Not surprisingly there are no details other than the announcement, no mention of potential costs, and no explanation how all this will affect any of the many impacts that he claims are caused by climate change. To date no New York State initiative related to climate has quantified the impact on global warming. This post estimates the impact for the New York Green New Deal mandate for 100 percent clean power by 2040 and eliminating all 2015 emissions from fuel combustion in the state.

Analysis

In the absence of any official estimate I did my own calculation. I simply adapted data for this emission reduction from the calculations in Analysis of US and State-By-State Carbon Dioxide Emissions and Potential “Savings” In Future Global Temperature and Global Sea Level Rise. This analysis of U.S. and state by state carbon dioxide 2010 emissions relative to global emissions quantifies the relative numbers and the potential “savings” in future global temperature and global sea level rise.   These estimates are based on the MAGICC: Model for the Assessment of Greenhouse-gas Induced Climate Change) so they represent projected changes based on the Intergovernmental Panel on Climate Change estimates. All I did in my calculation was to pro-rate the United States impacts by the ratio of New York emissions divided by United States emissions to determine the effects of eliminating all emissions from fuel combustion in New York State as well as the mandate for 100 percent clean power by 2040..

The first step is to quantify NY emissions. The New York State Energy and Research Development Authority prepared the Greenhouse Gas Inventory 1990-2015 which lists historical greenhouse gas emission data from 1990-2015 for New York State’s energy and non-energy sectors. In 2015 the NY total emissions from fuel combustion was 177 million metric. According to that report emissions from electricity generation were 29.1 million metric tons in 2015. The New York impacts were calculated by the ratio of the NY emissions reductions to the US reductions in the report. For example, the NY % of global total emissions equals the % of US global total (17.88%) times the NY Green New Deal goal (29.1) divided by the US emissions (5631.3). Those results are shown in table 2 eliminate 2015 co2 emissions from fuel combustion effect on global warming table 1 ny green new deal clean energy mandate effect on global warming. table 2 eliminate 2015 co2 emissions from fuel combustion effect on global warming lists the results for eliminating all 2015 GHG emissions from fuel combustion.

These calculations show current growth rate in CO2 emissions from other countries of the world will quickly subsume New York total emissions much less any reductions in New York CO2 emissions. According to data from the U.S. Energy Information Administration (EIA) and based on trends in CO2 emissions growth will subsume all of New York’s 2015 fuel combustion emissions in 81 days. Furthermore, using assumptions based on the Intergovernmental Panel on Climate Change (IPCC) Assessment Reports we can estimate the actual impact to global warming for fuel combustion emissions. The ultimate impact of the 177 million metric tons on projected global temperature rise would be a reduction, or a “savings,” of approximately 0.0026°C by the year 2050 and 0.0054°C by the year 2100. The clean energy by 2040 mandate effect on projected global temperature rise would be a reduction, or a “savings,” of approximately 0.00043°C by the year 2050 and 0.00089°C by the year 2100.

These small numbers have to be put in context. First consider temperature measuring guidance. The National Oceanic & Atmospheric Administration’s Requirements and Standards for NWS Climate Observations states that: “The observer will round the entered data to whole units Fahrenheit”. The nearest whole degree Fahrenheit (0.55°C) is over two hundred times greater than the projected change in temperature in 2050.

Although this change is too small to measure I am sure some will argue that there will nonetheless be some effect on the purported impacts. However if these numbers are put into perspective of temperatures we routinely feel then that argument seems hollow. For example, in Syracuse NY the record high temperature is 102°F and the record low temperature is -26°F so the difference is 128 °F which is over 27,000 times greater than the predicted change in temperature in 2050. The annual seasonal difference ranges from the highest daily average of 71.6°F to the lowest daily average of 23.2°F, or a difference of 48.4°F which is over 10,000 times greater than the predicted change in temperature in 2050. The average difference between the average daily high and average daily low temperature is 10.4°F or nearly 4,000 times greater than the predicted change in temperature in 2050. In order to give you an idea of how small this temperature change consider changes with elevation and latitude. Generally, temperature decreases three (3) degrees Fahrenheit for every 1,000 foot increase in elevation above sea level. The projected temperature difference is the same as going down 39 inches. The general rule is that temperature changes three (3) degrees Fahrenheit for every 300 mile change in latitude at an elevation of sea level. The projected temperature change is the same as going south 1.0 miles.

Conclusion

I do not think that there is any question why the State has not provided a quantitative estimate of the impact on global warming from the Green New Deal, REV or any other New York State initiative related to climate change. Clearly we can expect no discernable impact. The calculated values provided in this post are based on the “consensus” estimates of the Intergovernmental Panel on Climate Change which I personally believe over-estimate the impact of temperature changes caused by greenhouse gas emissions but do represent the justification for the New York Green New Deal. As shown claiming any observable impacts for the projected small change in temperature due to these emissions reductions is a stretch at best.
