Factors affecting energy supply
Variations in climate and geography affect potential for use of solar, wind, HEP, wave & tidal power
The cost of building new energy infrastructure e.g. nuclear power stations, wind farms & solar powered technology is very high
Wars and unstable governments in countries with large energy reserves e.g. the Middle East can affect their ability to export resources
Climate Change from burning fossil fuels led to international agreements e.g. 'Paris 2016' to reduce CO2, so countries can't burn as many fossil fuels as they used to
There is an unequal distribution of fossil fuels in the world so some countries have fewer resources & some resources are harder to access
Fossil fuels are non renewable or finite so they will not last forever. Countries that rely on consumption or production of these will eventually lose energy security
Areas at risk of natural disasters that can damage energy infrastructure may unwilling to risk developing some forms of energy e.g. nuclear power in Japan
Some LICs have great potential for energy production but cannot afford to exploit them e.g. Niger has large uranium reserves
The price of fossil fuels such as oil and gas can vary a great deal so countries who rely on these supplies may be unable to afford them at certain times
The renewable energy sources in the world are becoming more difficult to reach and costlier to exploit e.g. shale gas
Concerns over the safety of nuclear power and waste disposal have resulted in stricter regulations. So it has become more difficult to generate
Only some countries are allowed to develop nuclear energy the international community is concerned about development of nuclear weapons
