Grist's David Roberts tackles what's sure to be an unpopular question: What if the conventional wisdom, the one currently guiding the national political conversation about our energy future, is wrong? What if it's indeed not the case that we're going to need a "mix" of natural gas, nuclear, and renewable energy sources going forward? What if, instead, lending support to nuclear power means siphoning it away from the renewable energy sector? What if it only makes sense to choose one industry to devote our cleantech resources to? See Robert's post for a deeper analysis of the thought-provoking question.
