1. Energy Issues

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

     • By 2050 energy demand is expected to double

2. Worlds Energy Mix

   • Link to interactive map, on the worlds energy mix as well as Europe's energy usage
     • http://environment.nationalgeographic.com/environment/energy/great-energy-challenge/world-electricity-mix/ - Global energy mix
     • http://energy.publicdata.eu/ee/vis.html  - Europes energy usage
   • Currently, all the fossil fuels being used means that there is a lot of CO2 emmisons
     • http://environment.nationalgeographic.com/environment/energy/great-energy-challenge/global-footprints/
   • Countries gather their energy from a variety of sources, as one source may not be able to supply their energy needs
     • Currently the global energy mix means that 87% of energy resources come from fossil fuels
   • In the UKs the energy mix:
     • 70% is made of fossil fuels
     • Renewable energy is still below the UK average of 6%
     • Coal use has fallen by 40%
       • Most likely caused by coal mines closing in the 1980s
