It’s not easy being green.  Even seeming no-brainers like this solar initiative requires complicated tradeoffs between one environmental objective and another:

…The Ivanpah Solar Electric Generating System will send that power across California, the Golden State, early this year, becoming the largest solar plant in the world to concentrate the sun’s rays to produce electricity. Such utility-sized solar plants are beginning to appear across the US, with 232 under construction, in testing or granted permits, many in the south-west and California, says the Edison Electric Institute, which represents utilities. The scale of the largest plants is difficult to imagine in the eastern part of the country, where a relative lack of available open land and unobstructed sunlight have limited solar facilities to perhaps a tenth the size of the West’s plants. In the west, ample sun, wide-open spaces, financial incentives, falling costs and state mandates have made big solar plants possible…

…But even as the largest plants are helping utilities meet state requirements for renewable energy, the appetite for them may be waning, say experts. The next phase of solar development – especially in the east – may feature smaller projects located closer to cities. Environmental groups want regulators to look at sites such as landfills and industrial zones before allowing construction in largely undisturbed environments such as deserts. Continue reading →
