Northwest China's Qinghai Province has just run for seven straight days entirely on renewable energy.
From June 17 to midnight of June 23, Qinghai used only wind, solar and hydro power stations.
Quan Shengming, general manager of the provincial grid company, said during the period, electricity use was 1.1 billion kilowatt hours, equivalent to 535,000 tons of coal.
Hydro power plants supplied 72.3 percent of the electricity, with new energy like wind and solar supplying the remainder for the province, which is home to 5.8 million people, said Han Ti, vice general manager.
"Clean energy is the ultimate way. We need to reduce reliance on fossil fuel, improve our energy structure, and reduce carbon emissions," said Han.
China's enthusiasm for clean energy is pushing the global transition toward a low-carbon future with plans to invest 2.5 trillion yuan (about 370 billion U.S. dollars) in renewable energy by 2020, creating more than 13 million jobs, according to the National Energy Administration.
