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.
All these aspects would benefit from the selection of appropriate case studies.

All life on earth is sustained by energy from the sun. Plants and animals can store energy. Some of this energy remains with them when they die. It is the remains of the stored-up energy of ancient animals and plants that make up the fossil fuels that power our cars and factories today.But fossil fuels are non-renewable energy sources and will one day run-out and because burning them generates greenhouse gases, relying on fossil fuels for energy generation is unsustainable. Hence the need to find more renewable, sustainable ways of generating energy.
What do I need to know?
"Energy Resources" is NOT the same thing as "Types of energy".
"Types of energy" means "kinetic energy", "chemical energy" and so forth.
"Energy Resources" is about ways of getting energy so we can generate electrical power.
High in the hills of Kenya's Mau forest, some 20,000 families are facing eviction from their farms - accused of contributing to an ecological disaster which has crippled the country.
THE HEART OF KENYA
Mau forest is the largest in Kenya - the size of the Aberdares and Mount Kenya combined
10 million people depend on its rivers
They feed six lakes - Victoria, Turkana, Natron, Nakuru, Baringo and Magadi
Plus eight wildlife reserves - including the Masai Mara, the Serengeti and Lake Nakuru
The rivers have potential for 518MW hydro electricity - 41% of Kenya's total
In all, the forest provides an economic benefit of 20 billion shillings (£166m) per year (UNEP)
But already, a quarter of its 400,000 hectares have been destroyed by farmers and loggers
