BEIJING, Dec. 25 -- Non-fossil fuel will supply 11.1 percent of China's total primary energy consumption this year, up from 9.8 percent in 2013, an official said Thursday.

The share of coal may drop to 64.2 percent from 65.7 percent last year, Wu Xinxiong, director of the National Energy Administration (NEA), said at a conference on national energy work.

In 2014, total installed hydropower capacity will hit 300 million kW, installed wind power capacity will exceed 90 million kW and solar power capacity will reach 30 million kW.

The country has stepped up efforts in eliminating outdated thermal power units in its bid to combat air pollution, Wu added.

By 2020, non-fossil fuel will account for 15 percent of China's total primary energy consumption, the government has promised.
