To compare the first to wind energy production, be it electric power or 'primary wind power' is of course silly, unless most of the non-electric coal power would be used for useful purposes, which isn't the case AFAIK.

Using the total primary energy release from coal is of course even stronger number-pumping in favor of coal, but at least it adresses a real problem with current renewables: most of them are at least ballpark cost competitive when it comes to electricity generation, but not for low-quality heat generation. But I don't see how this is any different for nuclear energy. It's not as if we are going to use excess nuclear heat to heat buildings.
