IPCC: Almost 80 per cent of global energy to come from renewables by 2050

UN-commissioned report predicts 77 per cent of energy could come from renewable sources, but only if the right policies are adopted.

The full scale of the growth potential enjoyed by the global renewable energy industry has been underlined today with the release of a major new UN-commissioned report, which predicts that renewable sources could provide up to 77 per cent of the world’s energy by 2050.

The final version of the long-awaited Special Report on Renewable Energy Sources and Climate Change Mitigation (PDF) from the Intergovernmental Panel on Climate Change (IPCC) was released earlier today at an event in Abu Dhabi.

“With consistent climate and energy policy support, renewable energy sources can contribute substantially to human well-being by sustainably supplying energy and stabilising the climate,” said professor Ottmar Edenhofer, co-chairman of Working Group III, at the report launch. “However, the substantial increase of renewables is technically and politically very challenging.”

The report concludes that concerted policy efforts could result in the rapid rollout of renewable energy technologies, although the proportion of renewable energy will increase even without enabling policies.

It also predicts that the emergence of renewables as the dominant energy source could lead to cumulative greenhouse gas savings equivalent to 220 to 560 gigatonnes of carbon dioxide between 2010 and 2050.

The cuts delivered through this could play a major role in ensuring that concentrations of greenhouse gases remain below 450 parts per million, and that this could be sufficient to limit average global temperature rises to below two degrees centigrade.
