![]() ![]() However, with the recent resurgence in coal production, its share has rebounded to 26.6 per cent in 2005. By 2000, coal's share of total energy production had plummeted to 22.8 per cent. In 1961, coal lost its leading role to petroleum liquids. At the middle of the twentieth century, coal was clearly king, providing nearly 50 per cent of world energy production. Most of those changes have occurred among the fossil fuels. But even coal has shown new life recently from 2000 to 2005, it provided half of the increase in world energy production.ĭuring the past 55 years, these different growth rates by fuel source have changed the composition of world energy production considerably. Coal was the only laggard during the past half century, rising only 263 per cent from 33.7 to 122.2 quads. Petroleum liquids production also grew faster than overall energy production, growing 633 per cent from 23.1 to 169.3 quads. Natural gas production was the star, increasing 1383 per cent from only 7.1 to 105.3 quads. Among the fossil fuels, growth varied widely during this period. Fossil fuel production grew almost as rapidly, rising 521 per cent from 63.9 to 396.8 quads. From 1950 to 2005, energy production worldwide grew 571 per cent from 68.6 to 460.1 quadrillion Btu (quads). Growth in total energy production has been propelled by growth in fossil fuel production. 90%) hydroelectric power and nuclear electric power. World fossil fuel production per capita will thus begin an irreversible decline between 20.ĪOther is predominantly (approx. These production peaks are robust none of the fossil fuels, even with highly optimistic resource estimates, is projected to keep growing beyond 2050. The subsequent peak plateau will last for 10–15 years. Total fossil fuel production will continue to grow, but only slowly for the next 15–30 years. These scenarios differ primarily by the amount of ultimate resources estimated for each fossil fuel. Three possible scenarios-low, medium and high-are developed for the production of each of the fossil fuels to 2050. During the next half century, fossil fuel production will be limited primarily by the amount and characteristics of remaining fossil fuel resources. During the past half century, growth in fossil fuel production was essentially limited by energy demand. This growth, however, was irregular, providing for rapidly growing per capita production from 1950 to 1980, stable per capita production from 1980 to 2000 and rising per capita production again after 2000. All fossil fuels grew substantially during this period, their combined growth exceeding the increase in world population. From 1950 to 2005, fossil fuels provided 85–93% of all energy production. During the past century, fossil fuels-petroleum liquids, natural gas and coal-were the dominant source of world energy production. ![]()
