sendler2112 said: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..
It's a quote.
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.
