In 2011, green energy investments in the US rose by 33 percent to $55.9 billion, while Chinese investments in the technology remained relatively unchanged for the year at $47.4 billion.
According to BNEF, “the US figure was achieved thanks in large part to support initiatives such as the federal loan guarantee programme and a Treasury grant programme”, though their ranking could fall again by the end of this year, due to the Treasury grant programme having already expired while the country’s principal remaining support measure for renewable energy, the Production Tax Credit, is scheduled to expire by the end of 2012 as well.

Spending in solar energy, in particular, had been the cause for a global rise in clean energy investments in 2011, with the total investment in solar technology worldwide jumping by 36 percent to $136.6 billion.
“The performance of solar is even more remarkable when you consider that the price of photovoltaic modules fell by close to 50 percent during 2011, and now stands 75 percent lower than three years ago, in mid-2008,” said BNEF’s chief executive Michael Liebreich.

In total, global investments in clean energy technology reached $260 billion in 2011, with wind power being the second most invested technology for the year at $79.4 billion.
Still, Liebreich warns that 2012 might pose a larger challenge for the clean energy industry as “the European financial crisis continuing to fester, and the supply chain works its way out of some fearsome over-capacity.”
