Intermittent renewable energy generation which is usually located far from demand centers, while clean, cannot possibly power America. Only nuclear generation can. We should be using the sites of current coal fired power stations which have in place transmission and cooling infrastructure and are close to locations where energy is needed to build new nuclear capacity. As noted in the article, Democrats largely reject new nuclear power plants.
Secondly, we are not on track to reduce carbon emissions adequately to halt disastrous climate change. At this stage of the problem only geoengineering can save humanity. Republicans largely reject geoengineering and because they believe in crazy conspiracy theories refuse to support even research into how it might help.
With both parties standing in the way of necessary solutions to the looming climate disaster we are clearly fucked.
