I don't know about you, but I'm starting to forget what life was like before the Internet.

Think about it. When's the last time you got a stock quote from a newspaper? Went to the library to track down a fact? Called a travel agent to book a flight?

In a lot of ways, that's sad. But it's also incredible to think that a technology that evolved out of the U.S. government's reaction to the Soviet Union's launch of Sputnik has come to dominate our lives.

Even more incredibly ...
Investors who understood how profoundly the Internet would change our world have made an absolute fortune by buying shares of pioneering companies like Yahoo! (NASDAQ:YHOO).

That's why I was so intrigued when I read that a well-respected venture capitalist now sees a megatrend on the horizon that he says could be ...

"Bigger than the Internet by an order of magnitude"
In case you're unaware, an order of magnitude is a multiple of 10 -- meaning venture capitalist Ray Lane has found something he thinks could be 10 times as big as the Internet. And he would know.

After all, he's a partner at the famed venture capital firm Kleiner Perkins Caufield & Byers -- an early investor in dozens of millionaire-maker Internet companies, including Sun Microsystems and Intuit.

And he's not the only one who's taking notice
Fidelity Magellan manager Harry Lange has outlined several reasons why his fund began focusing more on "cleantech" in general, and on solar energy in particular:

  • Technological advancements and greater economies of scale are making it cheaper to produce electricity from solar energy.
  • Thanks to a declining cost curve and the rising cost of conventional fuels, solar energy is becoming more competitive in areas with high electricity costs.
  • Governments worldwide are providing tax incentives for both producers and consumers of solar energy.  

The next great bull market?
All of these factors certainly contributed to Wall Street's love affair with solar energy back in 2007. But then 2008 hit, and the market began selling off steadily, before heading into an all-out tailspin.

The solar sector was particularly hard-hit, and while those who snapped up shares at the March lows have been handsomely rewarded, long-term shareholders have been crushed.

Granted, much of this poor performance is due to general market turmoil, massive hedge fund sell-offs, cheaper oil and gas, tightening credit, and ever-present recession fears. But it reminds us that just because you recognize a developing megatrend, you're not guaranteed to cash in on it.

In fact, more often than not, those who jump on board without doing their due diligence will end up losing a fortune.

Just look at the Internet
As anyone who was a 20-something slacker working in Silicon Valley in the late 1990s can tell you, the Internet spawned more big losers than big winners -- by an order of magnitude.

That's why at Motley Fool Rule Breakers, we've been doing plenty of research on cleantech and keeping a close eye on solar stocks in particular -- but you won't find us recommending every solar stock under the sun.

Among our recommendations, you will find a few carefully selected cleantech companies, including Suntech Power (NYSE:STP) -- a proven leader in the solar industry.

We're also encouraging investors to take advantage of major discounts on an alternative-energy exchange-traded fund that gives you exposure to a wide range of companies involved in cleantech (you can get the name of the ETF absolutely free by accepting a 30-day Rule Breakers guest pass below).

Granted, nearly all solar stocks are still selling well below their 2007 highs. But as the economy recovers and the Obama administration begins to make good on its promise of massive investments in green energy, these stocks present a compelling profit opportunity.

10 times bigger than the Internet?
Only time will tell -- but at Rule Breakers, we're always on the lookout for the next millionaire-maker megatrend, and the next great growth stock.

Austin Edwards doesn't own shares of any of the companies mentioned -- but he does look forward to a world powered by sunshine. Suntech Power is a Motley Fool Rule Breakers pick. And yes, even the Fool's disclosure policy sneered at that pun about "recommending every solar stock under the sun."
