It’s no secret that environmentalists are going through a bit of an identity crisis when it comes to natural gas. Celebrities including Mark Ruffalo, Matt Damon, and Yoko Ono have aligned themselves with green groups like the Sierra Club to come out steadfastly against shale gas. Meanwhile others, including New York Mayor Michael Bloomberg and the Environmental Defense Fund, have boosted fracking as a “bridge” to wean the US off of coal, and usher in more renewables, a process that is already underway. But a report released this morning makes it clear that the renewables industry sees itself in the latter camp, forming an unexpected alliance with the natural gas industry. --Tim McDonnell, Climate Desk, 1 February 2013
