- Generating electricity
- Fuel for electricity
- Electricity generators in power stations are driven by turbines
- Coal, oil and natural gas are burned in fossil fuels power stations
- Uranium or Plutonium are used as the fuel in a nuclear power station. much more energy is released per KG from uranium or plutonium than from fossil fuels
- Biofuels are renewable sources of energy. Biofuels such as methane and ethanol can be used to generate electricity
- Energy from wind and water
- A wind turbine is an electrical generator on top of a tall tower
- Waves generate electricity by turning a floating generator
- Hydroelectricity generators are turned by water running downhill
- A tidal station traps each high tide and uses it to turn generators
- Power from the sun and the earth
- Solar cells are flat solid cells that convert solar energy directly into electricity
- Solar heating panels use the sun's energy to heat water directly
- Geothermal energy comes from the energy released by radioactive substances deep inside the earth
- Water pumped into hot rocks underground produces stream to drive turbines that generate electricity
- Energy and the enviroment
- Fossil fuels produce increased levels of green house gases which could cause global warming
- nuclear fuels produce radioactive waste
- Renewable energy resources can affect palnt and animal life
- Big energy issues
- Gas-fired power stations and pumped-storage stations can meet variation in demand
- Nuclear, coal and oil power stations can meet base-load demand
- Nuclear power stations, fossil fuels power stations using carbon capture and renewable energy are all likely to contribute to future energy supplies
- Fuel for electricity
