If you still doubt that the next bubble will be green, check out the latest from California. Green and clean technology gigs surged 36% from 1995 to 2008, beating the state's overall 13% job-growth rate for the same period, according to Silicon Valley-based research firm Collaborative Economics. Since California's on the leading edge of this sector, many see it as a sign of things to come for the rest of the country.

As of January 2008, there were only 159,000 green jobs in California, less than 1% of the state's total, following year-over-year growth of 5%. But, during that same period, total jobs in the state dropped 1%, suggesting that jobs in sustainability just might be more sustainable. Though these may seem like small numbers, keep in mind that the green sector job market is twice the size of the state's biotech presence and two-thirds the size of the software industry.

We're tired of bubbles, right? Anyone 30 or older has lived through two big ones so far, with a brief period of prosperity separating the decimation of dot-com largesse and mortgage-fueled paper wealth. It could take until 2014 for the jobs lost to be replenished, and there's little reason for optimism.

So, with the economy in the tank, we can focus elsewhere -- maybe on saving the planet. If we can't put green in our wallets, maybe we can add some to our lifestyles. Or, you could do both. Green technology could be the next boom in the United States, even if we do lag some parts of the world, and investing in clean solutions is really nothing other than investing in the next big thing. Even if you don't give a damn about climate change (or don't think it exists at all), the green market could likely become your employer -- or trigger the economic growth that will create your next job.

Some signs are visible already.

Venture capital investment in clean technology grew 10% from the second quarter to the third this year. According to a report by the Cleantech Group and Deloitte, 134 companies received investments of $1.59 billion – up from $1.2 billion in the second quarter. The sector's upward trajectory continues, with last quarter marking the second in a row of double-digit growth. In the first quarter of 2009, venture capital investment in cleantech companies hit a low of $1 billion.

The strong third quarter has made the cleantech sector the largest in the venture capital business, according to the Cleantech Group, pulling ahead of biotech. Twenty-seven percent of venture capital funds invested in the second quarter of 2009 went to cleantech companies – up from 3% at the beginning of 2004.

If you want to feel like what you do for a living makes a difference, you'll soon face an embarrassment of riches.

The alternative energy industry -- the green business -- is about to ramp up its hiring, with the next year likely to show an increase in demand, according to U.S. Labor Secretary Hilda Solis.

Not long ago, Al Gore seemed like a has-been. Then he snagged both an Academy Award and the Nobel Peace prize.

Will these accolades persuade him to run for president again?

Perhaps not. Perhaps there are more effective ways to enact sweeping change. To wit: Gore has become a partner at the esteemed venture capital firm, Kleiner Perkins Caufield & Byers. The firm has invested in such game-changing companies as Google (NASDAQ: GOOG), Intuit (NASDAQ: INTU), and Amazon.com (NASDAQ: AMZN).
