Biomass…photosynthesis Matter that was once alive
Biomass Burning wood for heat Corn ethanol for fuel Generating electricity
Wind Air particles in motion Caused by uneven heating of earth’s surface. Convection winds.
Wind- motion to electricity
Hydropower Force of moving water created by the water cycle
Hydropower Gravitational …..to electricity
Solar Radiant energy from the sun Photo voltaic cells convert to electricity Solar space heating houses
Solar
Geothermal Heat from core of earth the earth Radioactive decay
Geothermal Thermal NRG…. to electricity
Nuclear (Uranium) NRG in the nucleus of an uranium atom. Nucleus splits apart, creating heat.
Uranium (Nuclear) Nuclear to ….electricity
Hydrogen Used in batteries to produce electricity or burned as fuel Get it from water, biomass or natural gas
Hydrogen
Fossil Fuels A million years ago, plants and/or animals fell into swampy water or ocean bottoms. They were covered by layers of sedimentary rock. Due to heat and pressure they underwent chemical and physical changes. They became new substances, the fossil fuels. We burn them to release energy.
Petroleum..crude oil Chemical to…motion
Coal..remains of plants Chemical to …electricity!!!
Natural Gas-methane chemical to…heat
Propane- chemical to heat or fuel
