Solar May Produce Most of World’s Power by 2060, IEA Says

Solar generators may produce the majority of the world’s power within 50 years, slashing the emissions of greenhouse gases that harm the environment, according to a projection by the International Energy Agency.

Photovoltaic and solar-thermal plants may meet most of the world’s demand for electricity by 2060 -- and half of all energy needs -- with wind, hydropower and biomass plants supplying much of the remaining generation, Cedric Philibert, senior analyst in the renewable energy division at the Paris-based agency, said in an Aug. 26 phone interview.

“Photovoltaic and concentrated solar power together can become the major source of electricity,” Philibert said. “You’ll have a lot more electricity than today but most of it will be produced by solar-electric technologies.”

The solar findings, set to be published in a report later this year, go beyond the IEA’s previous forecast, which envisaged the two technologies meeting about 21 percent of the world’s power needs in 2050. The scenario suggests investors able to pick the industry’s winners may reap significant returns as the global economy shifts away from fossil fuels....

Nuclear power may halve market share by 2050 - IAEA

VIENNA | Tue Sep 20, 2011 10:46pm IST

...even in the high-growth scenario the market share will not change much from last year's 13.5 percent of total electricity generation, rising to 14 percent in 2030 before falling to 13.5 percent in 2050, the IAEA forecast said.

This reflects an anticipated rapid increase in total electricity output in the world over the coming four decades -- expected to more than triple by 2050.

As a result, the share for nuclear power could fall even if the sector's total output rises significantly.

In the IAEA's low projection, the share of nuclear power would fall to 11.8 percent in 2030 and to 6.2 percent in 2050...
