Nonrenewable energy sources are those that exist in a fixed amount and involve energy transformation that cannot be easily replaced. Renewable energy sources are those that can be replenished naturally, at or near the rate of consumption, and reused.

Active solar energy systems use solar energy to heat a liquid through mechanical and electric equipment to collect and store the energy captured from the sun. Photovoltaic solar cells capture light energy from the sun and transform it directly into electrical energy. Their use is limited by the availability of sunlight.
