China and the US signed eight green energy deals as the two nations move to enhance cooperation in environmental protection and improve energy efficiency, state media reported. No financial details of the agreements were revealed but several sectors were included including aviation biofuel, smart meters and cellulosic ethanol. Zhang Guobao, head of China’s National Energy Administration, said as the world’s two largest energy consumers, China and the US will further cooperation for development of renewable energy. "The US has advanced technology, and China has a huge market," said Zhang. China has set several environment targets for itself including an increase in use of non-fossil fuel energy to 15% of primary energy consumption by 2002 and to reduce carbon intensity by 40- 45% in 2020 from 2005 levels.
