The United States has undergone a stunning reversal of fortune thanks to fracking. A nation that once worried that it would run out of energy sources is now on the verge of becoming an energy export powerhouse. This transition should yield incredible profits for investors in companies such as Enterprise Products Partners (NYSE:EPD), Phillips 66 (NYSE:PSX), and Cheniere Energy (NYSEMKT:LNG).

Among the early leaders is Enterprise Products Partners, which has almost singlehandedly made the U.S. the world's top propane exporter. It's looking to do the same for exports of ethane and refined petroleum products. And if crude oil could be exported, Enterprise Products Partners has the access to water to make that happen rather quickly. It recently took the first steps in that direction by receiving government approval to export condensate

Enterprise, however, isn't alone in positioning to profit from exporting American energy. Phillips 66 is building its own propane export facility and recently acquired a refined petroleum products facility in the Gulf Coast that is strategically positioned for exports.

Meanwhile, Cheniere Energy is probably the best pure-play opportunity on natural-gas exports. Cheniere Energy's Sabine Pass LNG facility in Louisiana should be operational by the end of next year, and the company is already working on a second facility in Corpus Christi.

There's a lot of profit to be made from energy exports. I created the following slideshow to help investors see the full range of opportunities as energy exports rise in America. It takes a closer look at the positions of Enterprise Products Partners, Phillips 66, and Cheniere Energy, and also points to others that are positioned to profit from energy exports.
