Renewable energy is expected to make up 10 percent of the country's energy mix by 2010, up 2.5 percentage points from the current level, the National Development and Reform Commission (NDRC) said yesterday.

The NDRC announcement, part of the national renewable energy program for 2006 to 2010, came with concerns that the country's total energy consumption will in two years surpass the equivalent of a targeted 3 billion tons of coal at the current pace of economic development.

"China is rich in renewable resources but we need sophisticated technologies," the commission said in the program report.

The commission said the country will continue to tap its rich store of hydropower, which will reach 190 million kW by 2010, up from 117 million kW in 2005. Similarly, wind farms will generate 10 million kW by 2010, up from 1.31 million kW in 2005.

Solar power and bio-fuels will also play a bigger role in energy resources. The sun's rays are expected to generate 300,000 kW by 2010, up from 70,000 kW in 2005, while bio-fuels will produce electricity of 55 million kW in two years, up from 2 million kW in 2005.

The NDRC report, which can be downloaded at its website at www.ndrc.gov.cn, said its plan was readjusted with the country's mid- and long-term renewable energy program in mind.

In the long term, the authorities plan to make clean energy sources account for 16 percent of total energy consumption, by 2020.

Large-scale research is needed to maximize the potential of renewable energy to meet the country's demand, a commission source who did not want to be named told China Daily.

He said the authorities are committed to identifying and developing new energy sources and finding practical applications for them.
