Document Summary

Energy alternative: energy other than fossil fuels: hydroelectric power, nuclear power, biomass energy. Hydroelectric power kinetic energy move turbine generate electricity: dam(impoundment approach) (more common, harness kinetic energy from water to turn turbines, run of rivers ( ) Cons: cause flooding, prohibit fish from going downstream, destroy habitat. Should have played a more important role. France receive 79% power from nuclear power. Breeder reactor makes use of u-238: generate more power, less waste, use highly reactive sodium as coolant increase explosion. Pros: clean, reduce carbon emission, safer, less damage to landscape and less waste than coal-mining. Cons: expensive, small risk of big accident, less radioactive waste. Biofuels is a biomass sources converted into fuels into power vehicles. Biopower is produced when biomass sources are burned in power plants, generating heat and electricity. Cons: biofuel produced by fermenting carbohydrate crops, fuels for car, carbon neutral release no net carbon, economic benefits. Support local community: indoor air pollution, deforestation, affect crops growing.
