It used to be that all the energy to "make" renewables came from fossil fuels.Have you ever worked out how much energy would be required to build a renewables only future, by 2050??
Nowadays, depending where the making takes place, it could be less than 50% from fossil fuels. And each year that figure decreases.
By the way, you can insert 2010 and 1980 Arctic sea ice data into this interactive chart to see how far out you were at post #151.
