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 Non-Renewable Resources – United Streaming 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 • The source of most perpetual energy sources • Does not cause pollution Wind Power • Used to turn a turbine and generate electricity • Fastest-growing energy source • Does not cause pollution Geothermal Energy • Occurs when magma heats underground water • Steam and hot water are used to generate electricity Renewable Resources – United Streaming Futures Channel - Wind • http://www.thefutureschannel.com/dockets /science_technology/wind_farming/ The Futures Channel – Solar Power in Space http://www.thefutureschannel.com/dockets/r ealworld/space_based_solar_power/
