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.

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.

The balance between the amount of energy used and that lost, e.g. up chimneys of power stations.

The difference between energy supply and demand.

Primary energy sources (e.g. coal, wood, oil, gas) used to meet demand.

Refers to the flow of energy between producer and consumer.

Having less energy than is required to meet demand.

Means having access to reliable and affordable sources of energy.

Means having insufficient energy to meet demand.

Having more energy available than is required to meet demand.

Infinite, continuous energy sources which can be constantly renewed.

Fuel produced over millions of years from the breakdown of organic material, e.g. wood into coal.

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.

Energy generated by moving flows of water.

An economy which seeks to use low amounts of carbon-based energy.

Homes which are deliberately intended to use minimal energy.

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.

The sale of government assets to private shareholders, so that a company is run for profit rather than as a government service.

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.

Finite energy sources whose use means they will eventually run out.

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.

A country or state through which energy flows on its way from producer to consumer.

Energy Issues

Question	Answer
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.
