With gas prices projected to hit an all time high this summer, a new source of green energy aims to reduce our dependency on foreign fuel. So how does the process work?

It starts in Wyoming, where, via train, coal is transported to St. Louis. From there, it comes down the Mississippi River to Baton Rouge.

From cargo ships to a conveyer belt, the piles of coal are moved into the Big Cajun II plant where it's burned creating heat, thus, generating energy.

At times, Carbon Dioxide is emitted into the air, which NRG's president Jeff Baudier said is a Greenhouse gas.

"You're reducing the Greenhouse gas effect, and you're producing alternative fuels such as Ethanol and Biodiesel," said Baudier.

So in the bags where the testing is held, there's water, algae and Carbon Dioxide going in with Oxygen coming out.

The algae is then broken into fats and starches with the fat becoming biodiesel fuel and the starch turning into Ethanol -- both environmentally friendly fuels. As biologist Seth Staples said, the water is recycled.

"Whenever we can, we'll take the algae out of the water and then immediately poor the water back into the system," said Staples.

Rich in protein, whatever algae is left over can be used an animal feed or fertilizer.

So if the green algae turns into green energy, in a matter of a couple of years, we won't have to depend on foreign countries to provide us with fuel.

The plant is currently testing 400 species of algae to see if it can grow in the region's sunlight. If it can, the plant will expand to begin turning algae into energy.
