" Recently published research confirms what any venture capital investor would tell you: clean tech is hot.
The Cleantech Network and Environmental Entrepreneurs (E2) published a report summary on Tuesday fing that VC investment grew 78 percent in 2006 to $2.9 billion. Most of that money went into energy-related technologies.
That investment growth is anticipated to continue: the report expects numbers to climb to $19 billion by 2010.
The authors cited a few reasons for the investment boom in clean, or green, tech: concerns over global warming, higher energy prices, improved technology and changing public policies.
A lot of the money spent in venture-backed companies last year went to a handful of energy companies. With funding, those companies were able to ramp up their businesses from technology pilots to full-scale productions. A collection of solar and biofuel companies--Cilion, AltraBiofuels, Bloom Energy, Renewable Energy Group and Nanosolar--accounted for $600 million of investment in 2006.
Shall you have the idea of a solar panel producing biofuel together with a micro-yet-powerful wind generator serving as a WiMax basestation, it's time to call on the VC firm next door ;-)Although there is clearly a bull market in clean tech, there are also regular concerns over a bubble, particularly in solar and biofuels. There is also the concern that lower energy prices could make alternative energies and fuels less economical. "
