China has posted stronger capability of securing energy supply in the first three quarters of this year, according to the National Energy Administration (NEA) Tuesday.

The output of crude oil stood at 143 million tons in the January-September period, up 1.2 percent year-on-year and ending a falling streak for three years in a row, while the natural gas production grew at a faster pace, increasing by 9.5 percent to 127.7 billion cubic meters, said Song Wen, deputy director of the development and planning office of the NEA.

In the same period, China added 64.55 million kilowatts of power generation capacity, with non-fossil energy accounting for 56 percent, according to Song.

Energy transition for green and low carbon development was further promoted, Song noted.

By the end of September, 37.2 percent of the country's power plants with installed capacity above 6,000 kilowatts were installed with non-fossil energy, contributing 28.2 percent of electricity generation.
