1.3 How energy is generated and stored to make products GapFill

Energy can be harnessed from fossil fuels by burning them. Fossil fuels are  cheapnon-renewablerenewableclean but will eventually run out.   Oil, coal and gas are all forms of  fossil fuelhydroelectric energynon-finite resourcekinetic energy.   The burning of fossil fuels results in  a reduction in greenhouse gasesglobal warmingbiofuelsfracking.   Oil is used in different forms to provide different energy sources such as  petroldieselnuclear energyfossil fuel.   Gas is burned in  a power stationa wind farma turbinean oil refinery to create heat energy that is then used to heat factories and homes.   Nuclear energy is energy that is stored in atoms of  uraniumoilgascarbon.   The disposal of nuclear waste  is expensiveis easy to docan be done anywhereis cheap.   Wind, solar, tidal, hydroelectric and biomass are all forms of  non-renewable energy sourcesstorage systemsnuclear powerrenewable energy.    Generating systems that make use of water which is held in a reservoir and released is  hydroelectric powerbiomasswind powertidal power.   Batteries and cells are used as energy storage systems and they store energy  electricallymechanicallyvirtuallychemically.   Rechargeable batteries  are cheaperare more expensiveonly work onceproduce more waste in comparison to alkaline batteries.    Fossil fuelsBiofuelTidal powerGeothermal power is an example of a renewable source of energy. This is produced from waste organic matter which would otherwise be thrown away.    Fossil fuelsGeothermal powerTidal powerBiofuel is an example of a renewable source of energy. This is harnessed by natural water flow with the use of turbines.    Tidal powerWind powerFossil fuelsGeothermal power is an example of a renewable source of energy. This is harnessed by natural gusts of air in the atmosphere, captured by turbines.    Geothermal powerTidal powerFossil fuelsSolar power is an example of a renewable source of energy. This is harnessed by technology such as solar cells.
