Geog 1 - Energy - Key terms Flashcards
Bio-fuel
Crops grown for fuel
Combined Heat and Power

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
