Electricity source. The words " energy" and "power" are bandied about with regard to Rebuildable Electricity as if this is the total of energy that we are using but electricity is just a small part. There is 5X very expensive work to be done to convert all of society's energy consumption to electric even after getting to 100% rebuildables for current electricity production. Just putting RE electricity instead of fossil fueled generation into the existing wires is actually the easiest part..
Comparing RE primary energy with coal primary energy is more or less pointless, because 50-60% of coals primary energy is already wasted to heat rivers and make water vapor in those power plants. PV and wind are a lot more "elegant" in generating electricty not heating any rivers.
Yes, it is true that RE play a much smaller role for heating and mobility. That may change soon in the mobility sector with grwoning number of electric cars.
