The report also notes that "clean tech" - a category that includes clean energy along with water resource and environmental remediation technologies - has become the fifth largest venture capital investment category in North America, trailing only biotechnology, software, medical technology, and telecommunications. The report estimates that the clean energy market will grow from $39.9 billion currently to $167.2 billion by 2015. The trend has caught the attention of numerous financial institutions: According to the report, AIG, Allianz, and Goldman Sachs have released dedicated climate change policies in the past 12 months.
The clean energy investment trend was driven home recently by the announcement that an investment group had sunk more than $1 billion into clean technology ventures over the previous 18 months. The members of the Investor Network on Climate Risk invested in such technologies as hydrogen fuel cells, renewable energy, water technologies, and advanced materials. For example, the nation's two largest public pension funds - the California Public Employees' Retirement System and the California State Teachers' Retirement System - have invested a total of $350 million in energy efficiency and renewable energy technologies. In addition, the New York Retirement Fund has committed $30 million to the Carlyle/Riverstone Renewable Energy Infrastructure Fund I, which has raised a total of $600 million to invest in renewable energy projects.
