According to Global Trends in Renewable Energy Investment 2014, the report published by UNEP(United Nations Environment Programme) and BNEF(Bloomberg New Energy Finance), the new investment in renewable energy, excluding large hydro-electricity projects , dropped by 14% to $214 billion. However, renewable energy’s share of world electricity generation had increased to 8.5% in 2013. The report pointed out that the declining cost in the PV industry and the uncertainty of renewable energy policies in many countries were major reasons causing the decreased investment in renewable energy. Despite the fact that the renewable energy market had been gloomy in 2013, there still were some reasons for having a positive attitude for the future, such as manufacturers rebuilding margins, more cost competitiveness in the PV and wind industry, a rise in share prices, etc.
