(Yicai Global) Feb. 16 -- Eighty percent of 111 countries have started implementing elements of supportive energy policy frameworks, with emerging economies outperforming OECD nations thanks to more appropriate policy environments for sustainable energy, the World Bank said in a report.
The US, Denmark and Romania ranked the top three in terms of their energy efficiency scores, according to the Regulatory Indicators for Sustainable Energy (RISE) report, released by the bank yesterday. China ranked No.20, but still outperformed Japan and Switzerland.
The report said China has made the biggest contribution globally to avoiding energy consumption since 1990 and has been a leader in developing new approaches to energy efficiency. While keeping its annual economic growth rate above 6 percent, China's growing demand for energy has slowed mainly thanks to energy efficiency policies. China is already the world's largest hydropower and solar energy user.
According to the report, China has invested more in renewable energy than any other country. Between 2010 and 2015, investment -- including solar, wind, geothermal, small-scale hydro and biomass -- reached USD377 billion, more than the US and Germany, next two countries, combined.
But while China's renewable energy score is quite high, and the highest among middle-income countries in East Asia, the report warns that it does not integrate renewable energy into its generation and transmission planning in a transparent way and the network is not always adequate to take power from renewable energy sources.
