IPCC to discuss big world report on Renewable Energy

By far the most comprehensive UN assessment of the status and potential for the clean energy sector, the report weighs 164 separate development scenarios……

The report says there is virtually unlimited technical potential for renewables, with much of it coming from solar energy.

Renewables major part of 2050 world energy, Sydney Morning Herald, Marlowe Hood, May 7, 2011 Renewable power from the Sun, wind, water and biomass can and should generate a major portion of the planet’s energy supply by 2050, a leaked draft of a United Nations report says.

Renewables have the potential to bring power to the world’s poorest regions, boost energy security for nations dependent on imports, and curb the CO2 emissions that fuel global warming, the draft said.

The 30-page “summary for policy makers” — boiled down from 1,500 pages — is being vetted at a May 5-13 meeting of the 194-nation Intergovernmental Panel for Climate Change (IPCC) in Abu Dhabi, and will be unveiled on Monday.

By far the most comprehensive UN assessment of the status and potential for the clean energy sector, the report weighs 164 separate development scenarios……

The report says there is virtually unlimited technical potential for renewables, with much of it coming from solar energy.

Drafted before the Fukushima plantmeltdown in Japan undercut the so-called nuclear renaissance, the summary said renewables will likely make a higher contribution to low-carbon energy supply by mid-century than nuclear energy and carbon capture and storage (CCS) combined.

Overall, a majority of projections reviewed show a “substantial increase” — ranging from 3-to-20 fold — “in the deployment of renewable energy by 2030, 2050 and beyond.”

Many scenarios showed renewables reaching 200 to 400 exajoules (EJ) a year by mid-century in a world where total primary energy supply is forecast to be about 1,000 EJ, according to the International Energy Agency (IEA).

An exajoule is a unit of measure for energy….
