France is promoting via aggressive feed-in tariffs the expansion of solar photovoltaic. I believe this is quite a good thing even if our electricity is 90 percent low carbon. (80 percent nuclear and ten percent hydro)
Indeed, we will soon need additional capacity for both heat pumps and electric vehicles. However I believe the French (and other) government(s) should promote more aggressively solar water heaters.
Electricity is often generated by heating water. So using electricity to heat water is a very inefficient process. Using solar water heaters would enable us to change that.
