electricity production 6 marker

Question 1

what are the disadvantages of methods of Large scale electricity production using a variety of non-renewable resources.

Answer 1

fossil fuels:
1) non renewable resources will eventually run out
2) releases carbon dioxide and sulfur dioxide
3) extracting and transporting fossil fuels causes pollution and can change landscapes
nuclear power:
1) uranium used as nuclear fuel will eventually run out
2) many people are worried about the possibilities of an accident in a nuclear power station and don’t want to use nuclear energy
3) an accident in a nuclear power station could affect thousands or even millions of people. nuclear power stations must be safe, making them much more expensive to build than fossil fuelled power stations.
4) very expensive to dismantle
5) produce radioactive waste, which stays for millions of years. this must be sealed into glass or concrete and buried so radioactivity cannot damage the environment.
