Many different sources. There are atomic powered plants, as you know. There are also coal-burning and oil-burning plants, but those are becoming obsolete. There are hydroelectric plants, which sit on dams and use the pressure of the water to turn turbines. There are windmills -- miles of them in the open spaces between the mountains on the way between California and Arizona -- and there are solar panel arrays, although those are still pretty new. Of course, many people also have solar panels and passive solar devices on the roofs of their homes. There are a few geothermal plants, which use the heat of the earth's interior for their energy, and hydrothermal plants, which use the difference in temperature between the lower parts of the ocean and the upper levels. I don't know if anyone has actually built those yet, but they have been designed.

About half of it comes from coal. Hydrocarbons, mostly natural gas, account for about 20%, as does nuclear power. Hydroelectric power provides most of the rest of it, with a couple percent coming from wind and other renewable sources.

Nuclear, water, wind, natural gas, oil and coal driven steam engines. Next tidal power plants.

every source possible, burning coal, nuclear power, hydro electric dams, solar, wind, burning garbage, every town has a different source.

From the wall socket or batteries.
