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. |
Wave power | Energy generated from waves. |
