Energy security is the association between national security and the availability of natural resources for energy consumption. Access to cheap energy has become essential to the functioning of modern economies. However, the uneven distribution of energy supplies among countries has led to significant vulnerabilities. The ability of a nation to secure sufficient, affordable and consistent energy supplies for its domestic, industrial, transport and military requirements is termed Energy Security. It means that current and future energy needs have a high probability of being met, irrespective of economic or political instability. An IEP seeks to achieve an efficient balance between energy demand and supply in an effort to avoid constraints on economic growth. The demand-side of the energy equation is equally important. The development potential of energy relies heavily on energy solutions appropriate to the needs of the end-user. Countries like Russia and Canada, with surplus energy, are energy secure, some countries produce a lot of energy and some produce very little. The largest producers of energy are Russia, China and the United States.
