"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."

Changing your energy generation from burning something to turning a turbine with wind power, hydropower or geothermal power. Or just using solar, means that you have no waste heat for electrical generation.

Waste heat is only created when you burn a fuel to boil the water.

If you heat things electrically you still generate waste heat. Think electrical stove and its bigger industrial counterparts.
