Companies that supply energy to meet China’s insatiable appetite for power are likely to be good investment bets over the coming decades.

Consider that the International Energy Agency forecasted that Chinese energy demand would leap 75 percent by 2035, accounting for more than a third of the growth in global consumption. China now accounts for 17 percent of world demand for energy, but that number will rise to 22 percent in 25 years.

The growth in Chinese energy consumption has already been astonishing, according to the International Energy Agency report. Over the last decade, China’s energy demand has doubled. While China used only half as much energy as the United States in 2000, it actually surpassed the United States in 2009 as the world’s largest energy user.

China’s huge energy consumption and its resulting negative impact on the environment have prompted the country to invest heavily in alternative sources such as wind power.

China aims to lead the world in low-carbon energy output. It plans $735 billion in investment over the next decade in nuclear, wind, solar and biomass projects, notes the IEA.

“Given the sheer scale of China’s domestic market, its push to increase the share of new low-carbon energy technologies could play an important role in driving down their costs through faster rates of technology learning and economies of scale,” noted the agency report.
