This is one of the principles that that describe my pragmatic environmentalist beliefs.
Environmental initiatives often are presented simply as things we can do. Over at Climate Etc. the Planning Engineer coined this statement when he said that when his children asked “Can we do this?” he used to annoy his children with the answer “We can do almost anything we want, but we can’t do everything.” They came to learn that response meant that something “unthinkable” would likely have to be given up to indulge the extravagance.
This is a fundamental aspect of pragmatic environmentalism. While it is fine and appropriate to propose actions to reduce environmental risks that are technologically feasible, in the real world the costs to implement those policies carry costs that have to be considered. Moreover there could be unintended consequences.
As the Planning Engineer explains in his blog post: “There is no bargain to be found by pushing jointly for both more microgrids and the greater integration of “clean” resources. Having both will require huge sacrifices. If society’s utmost desire is a “clean”, highly reliable grid, resilient, secure grid – we likely can build that at some enormous cost. However, if cost is a factor impacting electric supply then tradeoffs will have to be made from among competing goals and technologies.”
