To me, so far, the only thing “driving the growth of “renewable energy”" appears to be the Energy put into senseless machinery which we are told is “makes renewable energy” (whatever THAT might be) – by all the old energy sources that it is supposed to be replacing.
Meanwhile, I continue to point-out that we do not have to tolerate the several hundred years of waiting which a “Moder wind turbine” takes to produce enough energy to enable another to be made, because it is readily possible to get several WHOLE percent of cost returned, per annum, from a sensible design – OF ABOUT THE RIGHT SIZE. The pennies just do not appear to have dropped into the requisite minds to waken them – probably to physical reality in general, but in particular the fact that the cost of any given “windfarm” is a necklace-shaped function of the Diameter of the TADs employed. This is because the cost of 4 T urbines of half the diameter, is half that of the One big one, whilst the cost of 4
A lternators of 1/4 the thro’put is double that of the One big one.
Lowest cost to do the job is for sizes where the T bill is about the same as the A bill. This happens at around 1 metre diameter.
