Then, it is true that more than the investments to be taken into account (even with their own importance), it is the output that matters because the manufacturing costs have largely decreased, and therefore the (theoretical) billing cost, combined with the gigantism of the wind turbines themselves and which are, for the most part, in the hands of the manufacturers of electricity ... nuclear and which thus make the rain and the good weather in this field.
finally HYDROELECTRIC PRODUCTION IS PART OF RENEWABLES but do not appear on these graphs since their depreciation is largely carried out.
I do not know if in the end the problem is at the level of different technos ....
Wind turbines ... ecologists do not want them
Nuclear ... ecologists do not want it
The dams ... oh la la les écolos do not want it
Coal ... yuck ecologists do not want it
Solar fields ... uh ecologists want ... in the desert and again.
In short the problem is not the technologies are the men ...
If I expand beyond the ecological microcosm then every techno you add ... people want but FAR from home ... basically at the NEIGHBORHOOD, such as prisons, psychiatric hospitals, incinerators, landfills, TGV lines, detours, airports, compost plants, and some of the best.
So what?
