The US is lagging badly behind other countries in the transition away from fossil fuels. Germany has led the way in solar power, Brazil in ethanol-fueled cars. But Ivanpah, and this decision to go with solar instead of natural gas in Minnesota, show that the US is getting on track.
The right-wing blogs, which are always eager to dredge up any negativity they can find about non-fossil-fuel energy, have pounced on the fact that Ivanpah has killed a small number of birds (not that they ever seem to care about all the birds killed by oil spills); also, a local population of endangered desert tortoises had to be relocated. Unfortunately, it's impossible to build a project of this size without some negative impact of some kind. Conservatives also grumble that solar electricity is relatively expensive; but the costs are coming down rapidly, and such comparisons also fail to take into account the actual costs of the alternatives, such as the constant risk of a nuclear accident poisoning a large territory, or the fact that continued reliance on fossil fuels would make the Earth uninhabitable in a century or two.
Japan's Fukushima province, site of the worst nuclear disaster since Chernobyl, has set a goal of 100% of its energy from renewable sources by 2040; Japan as a whole has shut down 50 nuclear reactors since the disaster. Germany has set a goal of 60% of energy from renewables by 2050. If they can do it, so can we.
