The share of total global electricity production generated by renewable energy is climbing, mainly because solar photovoltaic systems are becoming less expensive,according to a report released Monday by the United Nations Environment Programme and Bloomberg New Energy Finance.
Wind, solar and other renewables, excluding hydropower, were 8.5 percent of total global electric power generation last year, up from 7.8 percent in 2012, the report says.
That comes just after Bloomberg and Pew Charitable Trusts issued a report last weeksaying investments in renewables worldwide has been declining since their peak in 2011, with the U.S. lagging behind China in overall investments in wind, solar and other renewables.
The reports come about a week after the Intergovernmental Panel on Climate Change released the second part to its fifth assessment report, stating with certainty that humans are going to have to adapt to a world enduring climate change caused by greenhouse gas emissions from people burning fossil fuels. Renewables help reduce the climate-changing, energy-related carbon dioxide emissions.
