The Energy category covers the description, definition, and use of all types of energy. Questions of a general nature can be put in the general Energy category. Other sub-categories exist for Fossil fuels, Nuclear energy, and renewables such as Wind, Solar, Hydro, Tidal, and Wave power.
The sun gives out energy because there is hydrogen fusion going on inside it. The great heat and pressure of the sun permits the conversion of hydrogen to helium. Solar power can mean two things. Electricity is produced by collecting sunlight on solar cells which convert light into electricity. T…
