Energy – The ability to do work or make change. • A major energy transformation in our lives is the one that changes various energy sources into electricity. • Energy sources can be either renewable or nonrenewable.
Renewable energy sources are those that can be replaced in a relatively short period of time. Examples of renewable resources are solar energy, wind energy, biomass and hydropower.
Nonrenewable energy sources cannot be replaced as they are used. Examples of nonrenewable energy sources are the metal uranium used as a nuclear energy source and fossil fuels such as coal, natural gas and oil. A fossil fuel is formed from the buried remains of plants and animals that lived many, many years ago.
RENEWABLE RESOURCES A resource that is naturally replaced in a relatively short time. Examples: HYDROELECTRIC, BIOMASS, WIND, SOLAR, GEOTHERMAL
Solar– 0.5%https://youtu.be/yFwGpiCs3sshttps://youtu.be/bhcIJRdyrQg
Wind– 1.9%https://youtu.be/Z5c50-_hcD0https://youtu.be/Fep4CSRoreE
GEOTHERMAL– 0.2%https://youtu.be/D22Z_Ynz4fYhttps://youtu.be/DFQrE91kZwk
HydroELECTIRC - 2.4%https://youtu.be/q8HmRLCgDAIhttps://youtu.be/kx5rsUnFYmw
BioMASS - 4.8%https://youtu.be/yHWcddUZ35shttps://youtu.be/HZoPNJGi6ig
NONRENEWABLE RESOURCES • A natural resource that cannot be replaced as it is used. • Examples: OIL, COAL, NATURAL GAS, NUCLEAR
Fossil Fuels (oil, Coal, Natural Gas) 81.3% combinedhttps://youtu.be/zaXBVYr9Ij0
Nuclear – 8.5%https://youtu.be/FNNKhE1FNNMhttps://youtu.be/44ovdxOvP_A
Nuclear energy is formed by nuclear fission. It is EXTREMLY powerful! While nuclear energy does not emit any greenhouse gases, it does make radioactive waste. Nuclear material is incredibly dangerous. If accidents happen there are serious health and environmental repercussions. Nuclear – 8.5%
