P.3: Energy Resources

What are example of fossil fuels?

gas

oil

and coal

What is renewable energy?

energy than is be replenished at the rate it’s being used

What is bio-fuel?

fuel taken from living or recently living materials

What is nuclear power?

release of energy from nuclear fission

What is wind power?

uses wind to turn a turbine around, this turns a generator

What is wave power?

waves turning a floating generator

What is hydroelectric power?

rain water collecting in a reservoir which flows downhill and turns a turbine

What is tidal power?

the trapping of water, which is then released at high tide and turns a turbine

What are solar cells?

flat cells which turn the suns heat into energy

What are solar pannels?

solar cells connected to each other

What is geothermal energy?

energy transferred by substances deep inside the earth

What is a start up time?

time between requesting electricity and when is starts being generated
