“with wind the single-biggest contributor… Power production costs have declined “by almost half” … And the clean energy sector has created 50,000 new jobs… Ask me what was the impact on the electricity sector in Uruguay after this tragic war in Europe — zero.”

    The reference to waste heat could include the heat from burning fossil fuels that isn’t turned directly into work. Which is a lot.

    So you’re right, there will still be some waste heat and the reduction in production needs won’t be that drastic. But it’s still a significant chunk of the total!

      Yes of course, but a lot of energy is currently also used for heating things in cooking steel, chemical industry, concrete, etc. Those processes need energy as heat and directly produce waste heat. I agree it’s probably still significant. It’s just wrong to reduce energy consumption to “making things move”.

      Converting energy to power will always produce at least one of heat or light (also radiant heat) in the process.

      There is no 100% efficient power.

      But, electric is the closest you could get. Especially compared to any petroleum products
