I am curious how long after renewable energy displaces conventional methods combined with the predicted big reduction in pricing before heat becomes the next pollution bogey.
the cheaper it gets will just increase its use which for much of the world is a great improvement in quality of life but there is always some costs involved
Renewable energy is heat-neutral, at least the solar/wind types. The electricity is created from heat. Energy in photons that would otherwise strike the planet and become heat is turned into electrical power. In converting fast moving air to slower moving air a wind turbine extracts heat from the atmosphere and turns it into electricity. So now matter how many turbines and solar panels we build, they aren't pumping out any net heat.
I believe this holds true for hydro, but not so for geothermal as it moves net heat into the biosphere.
