Energy Issues

Bio-fuel Crops grown for fuel
Combined Heat and Power (CHP) power stations that produce eletricity and which also use their surplus heat either by recycling it, or piping it off to local homes so that it is not wasted.
Energy dependency the level of energy imports as a proportion of total energy consumption. The higher the proportion of energy imports, the more energy dependent the country is on others.
Energy efficiency The balance between the amount of energy used and that lost, e.g. up chimneys of power stations.
Energy gap The difference between energy supply and demand.
Energy mix Primary energy sources (e.g. coal, wood, oil, gas) used to meet demand.
Energy pathway Refers to the flow of energy between producer and consumer.
Energy poverty Having less energy than is required to meet demand.
Energy security Means having access to reliable and affordable sources of energy.
Energy deficit Means having insufficient energy to meet demand.
Energy surplus Having more energy available than is required to meet demand.
Flow resource Infinite, continuous energy sources which can be constantly renewed.
Fossil fuel Fuel produced over millions of years from the breakdown of organic material, e.g. wood into coal.
Geopolitics The study of the ways in which political decisions and processes affect the way space and resources are used. It is the relationship between geography, economics and politics.
Hydro-electricity Energy generated by moving flows of water.
Low carbon economy An economy which seeks to use low amounts of carbon-based energy.
Low carbon homes Homes which are deliberately intended to use minimal energy.
Peak oil The theorietical year inwhich oil is or was produced at its maximum and which can never be repreated as stocks decline.
Primary energy source Resources which can be burned to generate energy direct, e.g. coal, oil, and natural gas.
Privatisation The sale of government assets to private shareholders, so that a company is run for profit rather than as a government service.
Recyclable resource Reprocess resources, e.g. plutonium and heat capture systems.
Renewable energy sources Those whose flow is continuous, e.g. solar or wind power
Secondary energy source Energy sources generated using another fuel, e.g. electricity.
Solar power Energy generated from the sun.
Stock resource Finite energy sources whose use means they will eventually run out.
Tar sands Also known as oil sands, these are naturally-formed mixtures of sand or clay and a dense viscous form of petroleum called bitumen.
Trans-boundary pollution Pollution which crosses national boundaries, e.g. acid rain caused by burning fossil fuels which emit sulphur dioxide and nitrogen oxides.
Transit state A country or state through which energy flows on its way from producer to consumer.
Wave power Energy generated from waves.
