Generating Electricity- Explain how fossil fuels and nuclear power stations produce electricity
- Identify the advantages and disadvantages of these sources of energy for generating electricity Start up times
for different non-renewable sources. The examiner likes to make you think about these. LEARN THESE DEFINITIONS
Renewable - an energy source that can be renewed (made again) e.g. wood, solar power etc. Non-renewable - when this source of energy has been used, it is gone forever. Examples include nuclear power, coal, oil etc.. In the exam ... They could ask you why it would be uneconomical to connect remote areas to the National Grid. You could say: - It would be costly. It is unlikely that the remote area would be using too much energy so connecting the national grid would not balance it out. - You should consider the area first. Is it sunny? Then they can use solar power. Is it windy? They can use wind power. - You need pylons and usually remote areas have great landscapes. Pylons could disfigure it. - Cables required are not worth the money QUESTION TIME Download this file that has many questions about generating electricity. The mark scheme can be found at the end of the document.

In most power stations, energy is used to heat water into steam which turns a turbine connected to a generator that generates electricity. Usually, a fuel is used. A fuel is something that is burnt to release energy. However, energy sources like nuclear power and geothermal use fission to heat water.
