Energy Revision
definitions
renewable - Where the source of energy will not run out as it is infinite
non renewable - when the source of energy will run out as it is finite
A source of energy found in the ground that is formed from decomposed biomass
Energy created from water falling through turbines down a dam
Energy created by nuclear fission of radioactive atoms like uranium 235
Energy transferred from the sun with the use of solar cells
Energy from burning wood
Energy from burning specifically grown plants for biofuel
