There's less heavy industry and more high value added activities in China these days as the country's economic structure has changed drastically over the past decade.

Laszlo Varro -- the International Energy Agency's chief economist -- said in an interview with CCTV that China's economic policies have helped shape energy consumption and that the country is a leader in clean energy investment.

"From 2005 to 2013, China had very energy intensive, very investment driven growth. China was around 30 percent of the growth of global GDP, and was about 60 percent of growth of global energy consumption," he said.

"In the past two years, China is still 30 percent of the growth of global economy, but only eight percent of growth in global energy consumption,"

"There is a remarkable structural shift of the Chinese economy away from traditional heavy industry to high-tech, and high value-added service activities,"

"This is of course a very high priority of Chinese economic policy. In addition to the structural change, if you take the four most important low-carbon, clean-energy technologies -- hydro power, wind power, solar power and nuclear power -- China is the largest investor in all four of them."
