Wind turbines in Denmark. The nation has strong government support for wind power, and at times generates over 100% of its electricity from wind.

For the last few years I have been carefully following the debate about Vermont’s solar and wind development. There have been many valid points brought up by both advocates and opponents, and there seems to be a consensus opinion forming that revolves around a middle ground of sorts. Most Vermonters do agree that we need to transition toward a renewable-energy economy, but also that common-sense guidelines should be developed with regard to the approval and siting of wind turbines, solar arrays, and their distribution networks. I do sometimes wonder, however, if the body politic is occasionally losing sight of the forest for the trees, especially when I see the tiniest of details about specific projects being debated in various public forums.
In light of this, let me attempt to bring us all back a step. In the last several centuries, we humans have benefited tremendously from the use of fossil fuels; the power they contain has underpinned most of the world’s development and wealth creation. This energy source has also enabled human populations to mushroom, and, despite a gradual slowdown, world population is still increasing by about a million people every four days. The pressures that 7 billion-plus humans are putting on the planet are beginning to break it, as oceans acidify, the planet warms, wildlife habitats shrink, soil washes away, species vanish, pollution accumulates, and sea levels rise. Though the problems are many and disparate, a good portion of them are related to the use of fossil fuels, because using them has in some ways been a bargain with the devil. Despite the benefits that these fuels have given to mankind, we now better understand that they have dangers as well, and realize that burning them is not without cost, particularly with regard to CO2 emissions. Despite efficiency improvements across the board, CO2 levels in the atmosphere are still climbing steadily, and have now passed 400-parts-per-million—higher than any time in the last four million years. Worse, these higher levels hold a hidden danger, as atmospheric CO2 is quite stable, and continues to cause warming for centuries. This warming of the planet is also likely to exacerbate all of the other problems that we humans are causing, and many of them could become mutually reinforcing, or even spiral out of control in future decades. Mankind has unknowingly, and then knowingly, been playing a very dangerous game.
