Does using renewable or nuclear energy mean that no heat or pollution comes from appliances and machines?

electrical energy when converted back into mechanical energy will always release heat. the less heat generated is indicative of the effeciency of the motor. Research "energy star" appliances....

There is still "some" pollution from the nuclear plants. Why do you think they need to store the "waste" for 100+ years before it can be used?

renewable aka solar,wind,geothermal, ect. They still have initial consumption to build the plants, but make no waste out of them. Same with fusion/fission plants, i get the two confused.

pollution from appliances or machines... If your talking from the machines themselves, most do not. Gas burning stoves im sure release a small amount of carbon because i can't imagine burning off a molecule will turn something useful. Then you have smoke if you burn something

As far as the big picture, unless your off the grid, you are creating pollution by using anything that requires electricity. It's that whole you don't see it because its in the middle of no where, kinda thing?

Anyone can chime in

Directly, only the heat produced by any motors/etc. in the appliances will be made. Indirectly, well, there's the whole waste from nuclear plants (spent fuel rods, contaminated water, and finally the materials the plant's reactor is made of as they can't be safely recycled) and there is heat produced (nuclear plants simply use a reactor to heat water to make steam to run a steam engine (turbine usually), and of course there's a reason for those cooling towers on a plant, heated water is released from the plant as cool water is drawn in, in the process of cooling). It's not as obvious as a typical old fashioned coal plant belching out smoke but there is pollution.
