The United Nations Environment Program released Global Trends in Renewable Energy Investment 2012 June 11, finding that global investment in renewable energy hit $257 billion in 2011, a 17 percent increase over 2010, led by $147 billion in solar technology investment from rooftop photovoltaic installations in Europe, PV systems in China and the UK, and utility-scale solar generation in the United States. In the United States, investment rose 57 percent over 2010 figures to reach $51 billion. These numbers would have also been larger without PV panel price depressions, but the UNEP remains skeptical about continued renewable investment growth given the waning policy support the world over.
