It appears that alternative energy and natural gas companies caught the attention of traders Tuesday -- at least, that's what they're searching for.

If you want to know what stocks traders are interested in right now at this very second, you need look no further than what's hot in Google.

Here's what's hot today:

TheStreet.com's Jim Cramer says as crude goes higher, it makes more and more sense to go for other energy options.

Every day that oil goes up, there is a new set of technologies that had formerly been priced out of the market that comes back to life. Let's take wind. Wind, in itself, just seems so stupid. It needs, well, wind. Much of our country doesn't have enough wind to make this economic. There are only certain regions that can really benefit.

But when oil is at $130, SO WHAT! The parts of the country that have a lot of wind are nuts not to do wind. Wind, when properly integrated into the grid, costs 4 cents a kilowatt. The issue has been shortage of everything that goes into a windmill, because nobody in the chain thought it was worthwhile to mass-produce them. So even though the cost is low, no companies felt it was worth it because the market seemed so niche.

In other words, it was the wind supply chain that was the problem, because we only thought in terms of gigantic plants that created energy. But with nuclear not an option -- never will be in this country, if you ask me -- natural gas falling out of favor post-Katrina as being unreliable, and coal simply intolerable because of the climate problems, wind has become the most natural fuel of all.
