3.1.2 Energy generation and storage GapFill

Energy can be harnessed from fossil fuels by burning them. Fossil fuels are  pollution freerenewablenon-renewableenvironmentally friendly and will eventually run out.

Oil, coal and gas are all forms of  hydro-electrical energykinetic energyfossil fuelsnon-finite resources. The burning of fossil fuels results in  a reduction in greenhouse gasesfrackingglobal warmingbiofuels.

Oil is used in different forms to provide different energy sources such as  gascoalnuclear energypetrol. Gas is burned to create heat energy in  a microwavea power stationa hydroelectric planta turbine that is then used to heat factories and homes.

Nuclear energy is energy that is stored in atoms of  coalcarbonuraniumwater. The disposal of nuclear waste  rots down in the soil quicklyis expensiveis cheapcan be done by anyone.
