Energy is always from a source, the sources vary. Combustion is the most common energy. Combustion is the energy of the sun. Combustion is a chemical reaction. Electrical energy is mostly man made, converted from another energy, like combustion of coal, or from a turning magnet, like at a hydroelectric dam. For combustion, you do require three things on earth: fuel, oxygen, and a spark.

u need a source of energy either battery o generator 2 u need an energy transmiter like a wire 3 then an energy converter like a bulb

Three?

You need energy, or some sort of stored energy, usually in a chemical form.

You only need 1 thing, 'Matter' according to Einstein matter can be converted to energy.

Light bulb

Lighter

Crystal meth

I think to make energy,a.water-hydroelectricity.b.Air-we can make the electric.c.solar-we can make the solar power.
