__From the syllabus__
Candidates should be able to:


 * Describe the significance of fuelwood in LEDCs and of non-renewable fossil fuels in terms of their availability in certain areas and in terms of the contribution made by coal, oil, natural gas and wood in supplying vast amounts of energy.
 * Describe the growing significance of renewable energy supplies (geothermal, wind, running water, solar, biogas) to reduce dependence upon fossil fuels, to alleviate the world’s energy crisis, and to offer opportunities for the development of alternative energy sources.
 * Describe the factors influencing the siting of different types of electrical power stations with reference to those listed in the syllabus (thermal, hydro-electric power, nuclear).
 * Describe the uses made of water for agriculture, domestic and industrial demand. Candidates should also recognise that in certain areas there are water shortages which impact upon the local people and the potential for development. This leads to competition for the use of the available water resources and requires careful management.


 * Demonstrate the need for sustainable development, resource conservation and management in different environments
 * Describe how developments may pose threats to the environment when natural ecosystems are interfered with including: soil erosion, global warming, and pollution (air, water, noise and visual).
 * Identify areas at risk from these threats to the environment and describe attempts made to maintain, conserve or improve the quality of the environment.
