Unit 1: Cost benefit analysis and Swansea Bay



Plans for the Swansea Bay tidal lagoon power station are potentially a superb case study to use when teaching the multiplier effect, renewable energy, cost-benefit analysis, economies of scale and different forms of government intervention including subsidies for harnessing new energy sources.
According to an article in the Independent:

"The £850m, six-mile-long U-shaped seawall by the Swansea docks will not only generate enough electricity to power 120,000 homes for 120 years – it will also create nearly 2,000 construction jobs in the two years it takes to build; and it will leave the city with a tourist attraction drawing in up to 100,000 visitors a year."
