AT hot regions like eqatorial regions the water willl hot the upper layer of sea is very hot than as we go inside it heat absorbing meatals are kept tese will absorbs and thus we can convert into energy
Normally one would only think of converting thermal energy into electricity. Thermal energy is heat. One burn wood, fossil fuel, garbage, converting it that way into thermal energy. This in turn to...
When coal, oil, or natural gas burn this is a chemical reaction with oxygen, the heat released is used to raise steam and power a steam turbine/generator set to produce electricity.
No. It's usually the other way around. Solar = from the sun, and we can't recharge the sun. Turning electric energy into light OTOH happens in every lightbulb.
