Much of the world's energy supply is concentrated in the hands of a very small number of nations. Human energy consumption is increasing at a rate that some consider alarming, as of 2015.
The sunlight that reaches Earth in one minute contains enough energy to satisfy the demands of the entire planet for one year. Despite this abundance, a small number of countries exerts a great deal of influence by controlling fossil fuel energy distribution. Ten countries hold and control over two-thirds of the world’s oil reserves; the same is true for natural gas.
The rate of energy consumption is also steadily increasing. The energy consumed in the United States doubles every 20 years, and scientists predict a 55 percent increase in world energy consumption between 2008 and 2030. The average human consumed 230,000 kilocalories per day in 1975, compared to an estimated 12,000 kilocalories consumed daily 5,000 years earlier.
