1. 1. Describe the basic processes underlying global warming problems. 2. Identify the basics of climate modelling and employ a simple model. 3. Recognise the function of the basic components of a conventional power station, whether driven by coal, oil or nuclear power. 4. Describe the mode of operation of hydroelectric, tidal and wind turbines. 5. Compare the advantages and disadvantages of different methods of generating electricity. 6. Outline the UK and global energy outlooks and policy.

Energy is a vital resource in our society. Its use and misuse has implications for the environment, and these issues have assumed dramatic proportions recently. This module discusses the fundamental physics behind energy resources, both conventional and alternative, in order to provide a balanced view of environmental implications. In this approach, the interdisciplinary nature of the subject is evident, and the module gives special emphasis to modelling changes in the atmosphere - including the greenhouse effect. The module is suitable for undergraduates of any discipline.
