Energy Resources

1. Uses Of Energy

   • Cars
     • Fuel
   • In The Home
     • Gas
     • Electricity
   • At work
     • Electricity

2. Fossil Fuels

   • Coal
   • Oil
   • Natural Gas
   • Unsustainable
     • Being used faster than it is produced
   • Non renewables
   • Pollution from combustion
     • Carbon Dioxide
       • Greenhouse Gas
         • Rising sea levels - Flooding might occur
         • More severe weather
     • Sulfur Dioxide
       • Acid Rain
         • Kills forests and turns lakes and oceans acidic
           • Loss of wildlife
     • Oxides Of Nitrogen
       • Causes acid rain and is a greenhouse gas
       • Photochemical Smog

3. Reducing Energy Consumption

   • Turn Down Central Heating (Thermostat)
   • Less time in the shower
   • Don't leave appliances on standby
   • Switch off lights when you leave the room
   • Use more public transport
   • Re-use and Recycle

4. Alternative Technologies

   • Nuclear Power
     • Nuclear fission releases lots of energy
     • Nuclear Plant
       • Reactor Core
       • Control Rods
       • Fuel Rods
       • Containment
       • Coolant
     • Advantages
       • Releases little CO2 so doesn't add to global climate change or the greenouse effect
       • Doesn't give of oxides, sulfur or nitrogen so doesn't add to acid rain
       • Large amounts of energy from a small amount of fuel - lower fuel and fuel transportation costs
     • Disadvantages
       • Nuclear reactors originally used to make weapons - ethically wrong?
       • Waste is very dangerous - continues to be radioactive for thousands of years
       • There have been past accidents (Chernobyl) so some people think it is too big a risk
