Energy Resources

Nonrenewable resources A natural resource that is not replaced as it is used May take millions of years to form Includes oil, coal, natural gas, and nuclear energy

Oil A type of fossil fuel that is a thick black liquid Formed millions of years ago Most is found underground

Coal A type of fossil fuel that is in solid form Been used for thousands of years Used to fuel electric power plants Used to burn for heat.

Natural Gas A type of fossil fuel A mixture of methane and other gases Found underground

Nuclear Energy Energy converted during nuclear reactions Comes from energy stored in the nucleus of atoms

Renewable Resources A source that is naturally replaced in a short amount of time or through a cycle Examples: biomass, hydropower, and hydrogen

Biomass Living or formerly living material Can be made into fuel

Hydropower Power that is produced by flowing water moving over a waterfall or dam The most widely used source of renewable energy

Hydrogen Gas It is obtained from water – breaking the H & O bonds. A fuel that burns cleanly, with water as the byproduct

Perpetual (Inexhaustible) Resources A resource that exists in such a large supply that it is considered limitless Includes solar power, wind power, and geothermal energy

Solar Power Energy from the sun Does not cause pollution 2 ways to use: Solar Cells: convert radiation directly into electricity Radiation as heat for turbines

Wind Power Used to turn a turbine and generate electricity Most abundant Inexhaustible resource. Does not cause pollution

Geothermal Energy Occurs when magma heats underground water Steam and hot water are used to generate electricity
