Renewables don't really add much heat in to the atmosphere. Burning fossil fuels do. Fusion nuclear is a renewable energy source.

  Burning fuel isn't the only process of modern society that produces heat as a by-product. Lighting (though we're massively more efficient these days) and circuitry (computers and other electronic gadgets) for example. Then you have people running central heating more frequently as energy costs come down or people building less energy efficient housing because it becomes less important to people. I'm sure there are more examples I've not thought of too. Disclaimer: I also don't agree with the GP's position

    OP* Even all the heat generated by appliances and devices in the world combined is actually negligible in examining global warming. The problem is the greenhouse effect because that heat is a positive reinforncement feedback loop from where we get all energy ulimately -- the sun.

      > OP Both are correct in this instance (when replying to you I can't recall if it was the first post however I knew it was your parent / my grandparent post). > Even all the heat generated by appliances and devices in the world combined is actually negligible in examining global warming. I agree. Like I said, I don't agree with the original conjecture however it is still important to note that if one is only discussing waste heat production then the problem isn't just the generation of electricity. However the problems clean energy addresses are obviously more significantly other, far more hazardous, waste products. Hence why they're called "clean" energy.
