8.2.1 Identify different world energy sources. Students should be able to recognize those sources associated with CO2 emission. Students should also appreciate that, in most instances, the Sun is the prime energy source for world energy. 8.2.2 Outline and distinguish between renewable and non-renewable energy sources. 8.2.3 Define the //energy density// of a fuel. Energy density is measured in J kg-1 Energy density cartoon for [|xkcd]

8.2.4 Discuss how choice of fuel is influenced by its energy density The values of energy density of different fuels will be provided. 8.2.5 State the relative proportions of world use of the different energy sources that are available. Only approximate values are needed. 8.2.6 Discuss the relative advantages and disadvantages of various energy sources. The discussion applies to all the sources identified in sub-topics 8.2, 8.3 and 8.4.
