The United Nations is hinting at a new goal to generate 30 percent of global energy supplies from renewable sources by 2030, according to a report by Reuters. This goal would add on to the United Nations” previously announced plans to widen electricity availability by 2030 and to improve world energy efficiency by 40 percent by 2030.

Currently, Reuters reports that approximately 13 percent of energy used now comes from renewable sources, with most of that in the form of burning firewood in developing nations where many lack electricity for light and heat.

Reuters says the United Nations” renewable energy and electricity availability push will be known as the “30/30/30″ goals and will be tied to the agency”s efforts to end poverty in developing nations and to combat global warming. The United Nations” panel of experts says expects global warming to bring more heatwaves, droughts, mudslides and rising sea levels in they years to come.

According to Reuters report, U.N. Secretary-General Ban Ki-moon will formally launch the 2030 energy goals this year, aiming for adoption by world leaders at a once-a-decade Earth Summit in Rio de Janeiro in June 2012 as part of a shift to a green economy.

Reuters says it was unclear what it would cost to widen renewable energy use to 30 percent of all energy by 2030, he said.
