EPA OKs giant coal plant on Navajo land in New Mexico

After more than four years of deliberation, the U.S. EPA has bestowed an air permit to a proposed 600-acre coal plant on Navajo land in …

Hot, hot heat

By century’s end we can expect extremely high surface temperatures

Sure glacier melt, sea level rise, extreme drought, and species loss get all the media attention -- they are the Britney Spears, Paris Hilton, and Barack Obama of climate impacts. But what about good old-fashioned sweltering heat? How bad will that be? Two little-noticed studies -- one new, one old -- spell out the grim news. Bottom line: By century's end, extreme temperatures of up to 122°F would threaten most of the central, southern, and western U.S. Even worse, Houston and Washington, D.C. could experience temperatures exceeding 98°F for some 60 days a year. The peak temperature analysis comes from a Geophysical Research Letters paper [PDF] published two weeks ago that focused on the annual-maximum "once-in-a-century" temperature. Researchers looked at the case of a (mere) 700 ppm atmospheric concentrations of CO2, the A1b scenario, with total warming of about 3.5°C by century's end. The key scientific point is that "the extremes rise faster than the means in a warming climate."

If you are interested in distributed solar generation, you really should get the Interstate Renewable Energy Council's newsletter. I say this because they do critical work on net-metering and interconnection standards. They were also kind enough to publish a profile of our work, so props in return seems only right.

I wish they all could be California's plans

Energy efficiency, part 4

California and its utilities have achieved remarkably consistent energy efficiency gains for three decades. How did they do it? In part, a smart California Energy Commission has promoted strong building standards and the aggressive deployment of energy-efficient technologies and strategies -- and has done so with support of both Democratic and Republican leadership over three decades. I talked to California energy commissioner Art Rosenfeld -- a former DOE colleague and the godfather of energy efficiency -- about what the state does, and here are some interesting details he offered, as discussed in "Why we never need to build another polluting power plant":
