Now we know it's better to use that solar radiation to make electricity. In the end, if you're wondering where the heat in your home comes from, it's almost certainly one of the three main sources: combustion, electric resistance, or the outdoor air, ground, or water.

An energy resource is something that can produce heat, power life, move objects, or produce electricity. Matter that stores energy is called a fuel. ... In any event, the exploitation of all energy sources (with the possible exception of direct solar energy used for heating), ultimately rely on materials on planet Earth.

Crude oil, coal, wind and natural gas are all primary energy sources. Electricity is not a primary energy source, it's an energy currency (see electricity as an energy currency for an in depth discussion). Likewise, secondary fuels are also energy currencies and aren't primary energy sources, they must be made.

Three things are required in proper combination before ignition and combustion can take place---Heat, Oxygen and Fuel. There must be Fuel to burn. There must be Air to supply oxygen. There must be Heat (ignition temperature) to start and continue the combustion process.

Activity Overview: Primary energy consists of unconverted or original fuels. Secondary energy includes resources that have been converted or stored. For example, primary energy sources include petroleum, natural gas, coal, biomass, flowing water, wind, and solar radiation.
