How are you going to turn that fusion based heat into electricity? Coal and nuclear are uncompetitive simply from the cost of the steam side. Today you can just about give a steam plant free energy and it still makes a loss. Solar or wind does not have this limitation. CCGT gas plants gets around it by having a turbine giving raw mechanical power and then utilizing the same awful steam side to get the last percentage points of efficiency at a much smaller required scale. Unless you can step around the steam turbine I am not so positive on fusions future outside of incredibly small niches.
