The International Energy Agency is notoriously conservative on projections for renewable energy. The agency has embraced the need for more clean electricity and fuels to address climate change and peak oil, but its outlook for the future is usually far more conservative than how reality plays out. So when an official at the IEA says we could get up to one third of our global energy supply from solar photovoltaics, concentrating solar power, and solar hot water by 2060, that’s a fairly big piece of news. But even that projection may be conservative.
