Granted; energy production is the source of a huge part of current CO2 emissions. But even if you could magically turn every coal-burning plant into an nuclear plant; you'd still have to account of 73% of carbon emissions from transportation, industry, residential, commercial and agricultural sources. > Reconverting to electrical our other sources of emissions (heating, transport) where possible could cut another 20-30% of our emissions. Not sure what you mean by this. Transport and heating were never electrical to begin with, were they? Without changing our patterns of resource consumption this will not change. And that will not come without societal transformations that de-emphasise consumerism and with it capitalism to some degree.
