"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!

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
