The United States of America has re-claimed top spot in the clean energy investment race. China came in at number 2, followed by Germany and Italy. America invested over $48bn in the green energy sector. These figures show that USA sees the huge potential in green energy projects from the triple bottom line perspective. The US is making a statement and a lot of attention will be on China in the coming years in regards to their investment in green projects as they have ambitious targets for generating solar energy.
The table, published in a report by the Pew Charitable Trusts, showed that US invested more than $48bn (£30bn) in the sector, up from $34bn in 2010.
China slipped to second place, the authors reported, with investment only increasing by $0.5bn to $45.5bn.
Globally, overall financial backing in clean energy technologies hit a record $263bn, up 6.5% from 2010 levels.
The report, Who is Winning the Clean Energy Race, showed that G20 nations accounted for 95% of the investment in the sector (which does not include nuclear power).
The data, compiled by Bloomberg New Energy Finance, ranked the UK as seventh in the world, with $9.4bn of investment in 2011.
Over the course of the year, an additional 83.5 gigawatts (GW) was added to the world’s clean energy generation capacity, including almost 30GW of solar and 43GW of wind.
“The sector continues to expand and is outpacing growth in the overall (global) economy. The sector reached its trillionth dollar of investment last year,” observed Phyllis Cuttino, director of Pew’s Clean Energy Program.
“We now have 565GW of installed (generation) capacity around the world. That outstrips nuclear installed capacity by 47%.
“So I think the facts fly in the face of those individuals who say this is a niche industry. This a growing and maturing sector.”
She said market data showed that the US benefited in the short-term from attracting finances, however it was unlikely to be sustained.
“Investors rushed in to take advantage of expiring policies, such as tax incentives, loan guarantees, which expired at the end of 2011,” Ms Cuttino told BBC News.
“So when we look at the very rapid rate of growth in investment here in the US, it is hard to see how that could be maintained without the policy mechanism that spurred that growth.”
She suggested that there were signs that pointed towards a “drop off” in future clean energy investment as a result of “policy uncertainty”.
