" BEIJING Mario Edwards Jr Black Jersey , July 12 (Xinhua) -- As the development of clean energy hit new records, China, the world's largest energy investor and innovation center, has made stronger-than-expected efforts to accelerate the process.
Fatih Birol, executive director of the International Energy Agency (IEA), on Tuesday lauded China's efforts in the research and development of clean energy, saying ""China takes once again the leadership.""
CHINA'S CONTRIBUTION
On Sunday, China completed in the South China Sea a 60-day trial of mining gas hydrates, commonly known as combustible ice, marking a breakthrough in the search for alternative clean energy resources.
It was announced that the exploration produced over 300,000 cubic meters of gas, mainly methane, with an average daily extraction of more than 5,000 cubic meters of high-purity gas, and a highest daily output of 35,000 cubic meters.
China began its research on combustible ice in 1998, as one cubic meter of combustible ice, a kind of natural gas hydrate, equals 164 cubic meters of regular natural gas.
""What we are seeing is that the natural gas industry is in transformation,"" Birol said. ""We are seeing more and more unconventional gas being part of the total gas mix.""
The IEA said Tuesday in its report at the 22nd World Petroleum Congress held in Istanbul that as the world's largest energy investor, China saw a 25 percent decline in coal-fired power investment last year and is increasingly driven by clean electricity generation and networks, as well as energy efficiency investment.
