- - - - resources that can be replenished, they do not run out even though we are using them
      - Wind, caused by the movement of air and the wind turns a turbine which generates electricity
      - water has many ways of creating energy / electricity
        
        Tidal, a tidal barrage is built across a river estuary , this barrage contains electricity generators which are driven by the force of the water passing through
        
        Wave, this is when a series of waves enter a turbine where then air is compressed inside a chamber
        
        Hydroelectricity, this is when the water high up behind a dam has a lot of gravitational potential energy stored which is then transferred into a kinetic energy store while the water rushes down the tubes in the ram. The moving water then turns a turbine
      - Geothermal, this is when hot water and steam from underground can be used to turn a turbine and create energy
      - Solar, an example of this is solar panels as energy is transferred from the sun's radiation which creates energy is solar cells.
    - - energy resources that cannot be replenished, eventually run out because we are using them
      - Fossil fuels, this is when coal, oil and gas are formed over a million years from dead organisms and this is burnt in power stations to boil water which then turns into steam and turns the turbines
      - Nuclear fuel, this is when uranium and plutonium is used and the energy from it is transferred to energy is the thermal store through nuclear reactions then this energy is transferred to water to boil it into steam which then turns a turbine
  - - - Energy in the gravitational potential energy store (Ep) = mass (m) x gravitational field strength (g) x height (h)
    - - Energy in the kinetic energy store (Ek) = 0.5 x mass (m) x velocity² (v²)
        Ek x m x v (squared)
