- fossil fuel
- coal
- oil
- gas
- nuclear
- uranium/ plutonium
- more energy released than fossil fuels
- biofuels
- renewable
- Energy from wind
- turbine on top of tower
- turns generator
- Energy from water

- water falls downhill
- wave
- make floating generator move up and down
- not constant supply
- lots of cables
- tidal
- release high tide through turbines
- hydroelectric
- Energy from the earth
- Geothermal
- energy released by radioactive substances
- water pumped underground
- Geothermal
- Energy from the Sun
- Solar cells
- expensive
- many are needed
- heating panels heat water
- Solar cells
- Energy and the environment
- fossil fuels produce greenhouse gases
- nuclear fuels produce radioactive waste
- renewable energy can affect plant and animal life
- carbon capture
- collecting carbon
- The national grid
- network of cables and transformers that distributes electricity to our homes
- step up transformers
- step up voltage
- high voltage = less energy loss
- 230 V
- Fuel for electricity
