Clean energy on the rise, says UN report

The UN has concluded that clean energy could provide nearly a quarter of the world's electricity by 2030, due to a recent "gold rush" of investment in renewable, the Guardian reported on Thursday.
More than US$70 billion was injected into wind power, solar power and biofuels in 2006, 43% more than the preceding year, said the report. And while sustainable energy accounts for only 2% of the world’s total, the UN says 18% of all power plants under construction are in this sector.
The findings were outlined in the Global Trends in Sustainable Development annual review.
