Fossil fuel

Fossil energy sources, including oil and natural fuels, are non-renewable resources that formed when prehistoric plants and animals died and were gradually buried by layers of rock. Over millions of years, different types of fossil fuels formed -- depending on what combination of organic matter was present, how long it was buried and what temperature and pressure conditions existed as time passed.

Renewable Energy

Most renewable energy comes either directly or indirectly from the sun. Sunlight, or solar energy, can be used directly for heating and lighting homes and other buildings,

conserving energy or water

Energy conservation refers to reducing energy consumption through using less of an energy service. Conserving energy is an important way to reduce strain on the environment and bring down electricity expenses.
