Dams squeeze methane out of river water
There is a major controversy brewing on how carbon neutral large scale hydroelectricity really is. It has been known for a long time that dams emit both methane and CO2. The question has always been, how much of those emission are net? According to the International Rivers Network (PDF), studies by ecologist Philip Fearnside of the National Institute for Research in the Amazon (INPA) have shown that net methane emissions from hydropower are slightly higher than those from burning natural gas.

An op-ed in a UK paper
An opinion piece in The Independent argues that carbon trading is not the most effective way to reduce emissions, and is in fact counterproductive.
I've been known to make this argument myself, so I'm glad to see it in a major UK paper. (It will be quite a wait before we see it in major U.S. media.)

It’s a bad frame in the long term
(Hi, I'm Gar Lipow. I've worked extensively on renewable energy issues, and have written an (as-yet-unpublished) book on alternatives to carbon emissions, mentioned by John McGrath here. I'm going to be posting on efficiency and renewable technologies that can replace fossil fuels as well as on the economics and politics of phasing them out.)
"Energy independence" may be the buzzword in the renewable energy field. Even the invaluable Apollo Alliance emphasizes ending "dependence on foreign oil." The short-term political benefit is indisputable. The term polls in the Nineties, probably ahead of motherhood and apple pie.
But it is a loser in the long run. "Energy independence" reinforces a frame that works against renewables. The connotation: "it is all the fault of those outsiders, those others who addicted us to their seductive foreign oil."
