3.3.1: Outline the range of energy resources available to society
3.3.2 Evaluate the advantages and disadvantages of two contrasting energy sources.

Fossil fuels
-Cheap-Readily available technology
-Insustainability-Pollution and contribution to climate change
Nuclear Power
-Does not emit carbon dioxide-Readily available technology-Large amount of energy can be produce and very efficient (1Kg Uranium 20,000 times energy than coal)
-Radioactive wastes can remain for thousands of years-Risks of disasters (Chernobyl)-Non-renewable of uranium-Long time to build
Hydroelectric Power
-Reliable form of energy- Cheap to run once constructed
-large affect to environment surround it (loss of habitats)-Building cost is high
Tidal Power
-Expensive-Could have impact on wildlife
Solar Power
-Renewable-Cheap for heating homes
-Very expensive-Only work half of the time
Wind Power
-Renewable-Once set up, low cost to run it
-Limited area to built-Hazard to wildlife
-Produce emission-Require large amounts of land to grow the biofuel crop
-Does not deplete natural capital-Readily available resources
-Produce carbon dioxide
-Low emission-Renewable
-Limited sites-High cost to set up

3.3.3: Discuss the factors that affect the choice of energy sources adopted by different societies

Factor that could affect the choice of energy
  • Availability
Resources within or near to a country are better than those further away
  • Economic
If an energy source is more expensive than others, it would reduce the likelihood of it been chosen.
  • Cultural
e.g Chernobyl disaster would cause USSR unlikely to choose nuclear energy
  • Environmental
If an energy source is harmful to the environment, some societies might not choose it
  • Technological
Higher technology may require expensive training of the workforce
