Physics - Energy Resources

Gas, oil and coal are examples of fossil fuels

A renewable energy resource is one that is being (or can be) replenished as it is used

Fossil fuels will eventually run out - they are non-renewable resources

Bio-fuel is any fuel taken from living or recently living materials, such as animal waste

Nuclear power describes the release of energy due to nuclear fission

Wind Power involves the use of wind to drive the blades of a turbine around, which turns a generator

Wave Power involves waves turning a floating generator

Hydroelectric Power involves rainwater collecting in a reservoir flowing downhill, the flowing water drives a turbine

Tidal power involves the trapping of water behind a barrage, the high tide is then released into the sea, turning turbines in the process, which in turn drives a generator

Solar cells are flat solid cells that use the Sun’s energy to generate an electrical current directly

Solar cells connect together to male solar panels

Solar heating panels use the sun’s energy to heat water directly

Geothermal energy comes from the energy transferred by substances deep inside the earth

Start up time is the time taken between requesting electricity and to be generated and when it starts generating electricity
