Oil is Still World's Largest Energy Source, But Coal and Natural Gas are Gaining
Oil remains the world's leading energy source - for now. In recent years, coal and natural gas have proven themselves increasingly important resources across the globe. Global consumption of coal increased 5.4 percent in 2011, to 3.72 billion tons of oil equivalent, while natural gas use grew 2.2 percent, to 2.91 billion tons of oil equivalent. Both are primary fuels for the world’s electricity market, and because they are often used as substitutes for one other, their trends need to be examined together.
The bulk of coal use is for power generation, with smaller amounts being used in steelmaking. Spurred mainly by rising demand in China and India, coal’s share in the global primary energy mix reached 28 percent in 2011—its highest point since the International Energy Agency began keeping statistics in 1971. Although the United States remains one of the world’s largest coal users, just over 70 percent of global demand in 2011 was in countries outside of the Organisation for Economic Co-operation and Development (OECD), including China and India. Consumption in non-OECD countries grew 8 percent in 2011 to 2.63 billion tons of oil equivalent.
China alone accounted for nearly half of all coal use in 2011. India is the second largest contributor to rising coal demand and is the world's third largest coal consumer, after surpassing the European Union in 2009. The United States remains the second largest coal user, even though U.S. demand decreased by around 5 percent in 2011 and continued to fall in 2012 due to the shale gas boom and the abundance of cheap natural gas. Even with declining demand, the United States still accounts for 45 percent of coal demand within the OECD.
Coal production, like consumption, is concentrated mainly in China. But the United States holds the largest proved coal reserves, with 28 percent of the global total, followed by Russia at 18 percent, China at 13 percent, Australia at 9 percent, and India at 7 percent. Together, these five countries accounted for three-quarters of proved coal reserves as well as three-quarters of global coal production in 2011.
