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

I can't even remember the last time I went to my local video store instead of just logging onto Netflix (Nasdaq: NFLX), called a travel agent instead of just logging onto Orbitz, or looked up a stock quote in a newspaper instead of on Yahoo! Finance.

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 foresaw how profoundly the Internet would change our world have been able to make an absolute fortune from it.

Take those who understood the potential of e-commerce, for example. Most people scoffed at the idea of buying retail goods "online," but early investors in Amazon.com (Nasdaq: AMZN) and eBay (Nasdaq: EBAY) have grown their money by as much as 500% and 1,000%, respectively.

And he's not the only one who's taking notice
In a recent shareholder update, Fidelity Magellan manager Harry Lange outlined several reasons why his fund has begun to focus more on "cleantech" in general, and on solar energy in particular.

The next great bull market?
All of these factors contributed to Wall Street's love affair with solar energy in 2007:

Stock

Gain in 2007

Suntech Power

142%

SunPower (Nasdaq: SPWRA)

251%

First Solar (Nasdaq: FSLR)

795%

In fact, by the end of 2007, it looked as though Ray Lane might actually be understating the case. 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 2009 hasn't been much better. Continued...
