Access to cheap energy has become essential to the functioning of modern economies. However, the uneven distribution of energy supplies among countries and the critical need for energy has led to significant vulnerabilities. Threats to global energy security include the political instability of several energy producing countries, the manipulation of energy supplies, the competition over energy sources, attacks on supply infrastructure, as well as accidents and natural disasters.^[1] It is also the limited supplies of the most common forms of primary energy, i.e. Oil and Gas that changes perceptions on this topic. Although plenty of coal, up to 155 years worth, is readily available^[2], coal is not the fossil fuel of choice for many more advanced countries because of its highly polluting nature. The potential need to change our primary energy sources in the foreseeable future is the crux of the energy security question, leading to higher prices, more limited access to sources of energy, competitions and political troubles, which in turn make the threat even larger.

One of the leading threats to energy security is significant increases in energy prices, either on the world markets – as has occurred in a number of energy crises over the years – or by the imposition of price increases by an oligopoly or monopoly supplier, cartel or country. In some cases the threat might come from a single energy superpower – those states able to significantly influence world markets by their action alone. Rather than just manipulating prices, such suppliers might go beyond this by suspending or terminating supplies. This has been done to apply pressure during economic negotiations - such as during the Russia-Belarus energy dispute - or to apply political pressure, for example by OPEC in response to Western support for Israel in the Yom Kippur War. Suspension of supplies may also come about as a result of world-wide international sanctions against a country.

Energy plays an important role in the national security of any given country as a fuel to power the economic engine.^[3] Hence, threats to energy security can also result from physical damage to the energy infrastructure either of the supplier, or of the importer as a result of natural events, misfortune, terrorism, or warfare. The political and economic instability caused by war or other factors such as strike action can also prevent the proper functioning of the energy industry in a supplier country.

In recent years, new threats to energy security have emerged in the form of the increased world competition for energy resources due to the increased pace of industrialization in countries such as India and China. Although still a minority concern, the possibility of price rises resulting from the peaking of world oil production is also starting to attract the attention of at least the French government.^[4]

In the future it is possible to envisage threats to energy security emerging not as a result of energy prices, but as a result of increases in the price of carbon emissions within carbon emissions trading schemes, or from international political pressure to reduce emissions.

Increased competition over energy resources may also lead to the formation of security compacts to enable an equitable distribution of oil and gas between major powers. However, this may happen at the expense of less developed economies. The Group of Five, precursors to the G8, first met in 1975 to coordinate economic and energy policies in the wake of the 1973 Arab oil embargo, a rise in inflation and a global economic slowdown.^[5]

Long term measures to increase energy security center on reducing dependence on any one source of imported energy, increasing the number of suppliers, exploiting native fossil fuel or renewable energy resources, and reducing overall demand through energy conservation measures. It can also involve entering into international agreements to underpin international energy trading relationships, such as the Energy Charter Treaty in Europe.

The impact of the 1973 oil crisis and the emergence of the OPEC cartel was a particular milestone that prompted some countries to increase their energy security. Japan, almost totally dependent on imported oil, steadily introduced the use of natural gas, nuclear power, high-speed mass transit systems, and implemented energy conservation measures,^[6] It has become one of the world leaders in the use of renewable energy.^[7] The United Kingdom began exploiting North Sea oil and gas reserves, and became a net exporter of energy into the 2000s.

In other countries energy security has historically been a lower priority. The United States, for example, has continued to increase its dependency on imported oil^[6] although, following the oil price increases of 2004-2006, the development of biofuels has been suggested as a means of addressing this.^[8]

Increasing energy security is also one of the reasons behind plans for an oil phase-out in Sweden, together with a block on the development of natural gas imports. Greater investment in native renewable energy technologies and energy conservation is envisaged instead. India is carrying out a major hunt for domestic oil to decrease its dependency on OPEC, while Iceland is well advanced in its plans to become energy-independent by 2050 through deploying 100% renewable energy.

Many countries hold strategic petroleum reserves as a buffer against the economic and political impacts of an energy crisis. All 26 members of the International Energy Agency hold a minimum of 90 days of their oil imports, for example.^[9][10]

The value of such reserves was demonstrated by the relative lack of disruption caused by the 2007 Russia-Belarus energy dispute, when Russia indirectly cut exports to several countries in the European Union.

Compared to petroleum, reliance on imported natural gas creates significant short term vulnerabilities. Many European countries saw an immediate drop in supply when Russian gas supplies were halted during the Russia-Ukraine gas dispute in 2006.
