Venture capitalists are people, just like you and me. They put their pants on one leg at a time, and are prone to making investing mistakes just like the rest of us. That said, it's hard to deny that some VCs are clearly better than others. And one of Silicon Valley's more successful and higher-profile VCs is John Doerr. Among his big wins are early investments in Sun Microsystems
This success, I believe, gives his words some weight. And to this end, when he says, as he did yesterday, that global warming is real and that "cleantech" is "the biggest economic opportunity of this century," my ears -- and yours -- should perk up.
It's not that the idea of cleantech being a big investment opportunity is new. The Motley Fool, myself, and others have been writing about it for some time. Instead, it was Doerr's explanation of how cleantech can help address global warming that I found so interesting. He laid out four steps for solving global warming, which, when viewed in aggregate, can provide investors with a useful framework for thinking about how to invest in cleantech.
First, Doerr said the U.S. government should adopt a mandatory goal of reducing greenhouse gas by 25% by 2010. This is an ambitious goal and, even with Democrats now in control of both houses of Congress, I feel it is unlikely to be achieved. Nevertheless, I do believe some controls are coming, and investors can profit by understanding which companies are getting ahead of the curve and positioning themselves to benefit from government mandates. For instance, I have written before about Duke Energy's
Second, Doerr called for the adoption of renewable sources like solar and wind. This is hardly a bold call, but investors are encouraged to give serious consideration to investments such as Motley Fool Rule Breakers recommendation SunTech Power
Third, he said the U.S. needs to reinvigorate its biofuels industry. To a degree, this is already happening. Archer Daniels Midland
Finally, Doerr said there needs to be more investment in technologies that can remove existing carbon dioxide from the atmosphere. At the present time, I am unaware of companies that are doing this, but I do know that advocates of nanotechnology are confident that new nanoparticle catalysts or perhaps tailor-made nanofilters might soon be able to help in this regard.
There will, no doubt, be no shortage of companies working on such technologies, but I would encourage investors to keep an eye on the big boys like BASF
The bottom line is that, like Doerr, I believe cleantech will be huge. I also believe there will be no shortage of technologies and companies taking part in the solution. But before they invest in the field, I would encourage Fools to be strategic about how they want to approach the opportunity. After all, just because the opportunity is big doesn't mean everyone's profits will be, too.
