Q

Give an advantage and a disadvantage of using nuclear power compared to fossil fuels

A

Nuclear power is more environmentally friendly, as unlike fossil fuels, it doesn’t directly emit sulfur dioxide or carbon dioxide. However, the nuclear waste produced is dangerous and difficult to dispose of. There’s also the risk of a major nuclear catastrophe

Q

Explain why bio-fuels are considered a fairly reliable energy resource

Q

Explain why fossil fuels are currently a reliable resource. Suggest why they may not be a reliable resource in the future

A

Fossil fuels are reliable at the moment because they can be extracted from the Earth at a fast enough rate that power plants always have fuel in stock to meet demand. However, they are slowly running out, so in the future they will be harder to obtain, and there will come a point when supply will not be able to meet demand
