Supporting low-impact forms of energy generation — cleantech, as it’s called — has been a hot topic politically and socially and has been a subject of mainstream debate and politics for the past 10 years. As a result of consumer, regulatory and private interest in the cleantech sector, it has also been a hot topic for investing, and venture-capital investment in cleantech increased exponentially in the past decade. In 2001, venture capitalists invested roughly $507 million in clean-technology companies. By 2008, annual investment in the sector was $8.4 billion.
Where did it go?
Much of the early investment in cleantech was done in the form of large deals with relatively small equity investments alongside massive debt-capital structures to help finance major infrastructure projects in solar power, wind power and smart-grid energy distribution. At first it appeared as though investors’ bets on cleantech would pay off: The price of oil skyrocketed to nearly $150 per barrel over a six-month period in 2008, and equity indexes that tracked the performance of public cleantech companies became extremely popular among hedge fund investors.
The 2008 election of Barack Obama and a Democratic majority in both the House and Senate was expected to lift the industry, as a climate-conscious Democratic administration would make significant investments alongside private investors and create incentives to invest more capital in cleantech, thereby increasing company valuations.
