Energy

1. Non-renewable energy resources
   1. Resources that have been built up, or evolved over time.
   2. Also known as stock resources
   3. These types of energy resources have a 'reserve' and cannot be used without depleting the stock, due to formation being slow
   4. Examples of this type of energy include
      1. Oil
      2. Coal
      3. Gas
2. Renewable energy resources
   1. Also known as flow/stock resources
   2. Resources that have a natural rate of avalibility
   3. These sources of energy yield a continuous flow, that can be consumed at anytime
   4. Renewable energy are spilt into 2 different areas
      1. Critical
         1. Sustainable energy resources which require management.
         2. e.g. Forests, plants, animal waste
      2. Non-critical
         1. Everlasting resources
         2. e.g. Tides, Waves, Wind, Solar energy

1. Currently the global energy mix means that 87% of energy resources come from fossil fuels

1. 70% is made of fossil fuels
2. Renewable energy is still below the UK average of 6%
3. Coal use has fallen by 40%
   1. Most likely caused by coal mines closing in the 1980s
