Renewable energy's possible role 'underestimated' http://apocadocs.com/s.pl?1237294485
Renewable energy could play a much larger role in supplying the world's energy needs than previously estimated — but it won't come cheap, according to a new study.
The research, presented at the International Scientific Congress on Climate Change in Copenhagen, Denmark, this week (11 March) says that renewable energy could supply 40 per cent of the world's energy needs by 2050.... If renewable technologies were given the same government attention and financial backing as nuclear energy was in the 1970s and 80s wind energy and solar power would cost the same as traditional electricity generation by 2020–2025 and 2030 respectively, said Lund. But such ambitious targets require substantial financial investment, Lund warned. The technologies would require global support of US$12.8 billion to US$25.5 billion per year and without this backing wind and solar energy would contribute less than 15 per cent of the world's energy output.
