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

GeothermalThermal 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 oilChemical to…motion

Coal..remains of plantsChemical to …electricity!!!

Natural Gas-methane

chemical to…heat

Propane- chemical to heat or fuel
