Energy Flashcards
What is energy mix?
The proportion of different sources of energy used by a country to meet demand.
Give TWO physical factors that can influence energy mix.
Natural resources - are there accessible fossil fuels?
Climate/ Landscape - is it suitable for solar, wind, HEP, or wave?
Tectonic Activity - is it suitable for geothermal?
Give TWO human factors that can influence energy mix:
Development/ wealth - can a country afford to exploit/ import resources? Is it worth it? Price?
Technology - do they have the technology to develop new types of energy?
Political - Government priorities.
Attitudes - of the population/ pressure from environmental groups.
Give 3 renewable energy sources:
Wave/ tidal
