Gas prices on the rise, again!
Gas prices are rising again, and could reach as high as $5 a gallon, but scientists are working diligently to reduce our reliance on fossil fuels by working to create fuel with renewable resources and even everyday waste.
Here are some of the substances that you could end up filling your gas tank with in the next several years, and they could be cheaper than gas, auto analysts say.

Garbage - Alternative Fuel
Biogas from raw garbage, including food scraps, leaves and plants can be used to create liquid fuel through the fermentation process.
An ethanol plant in Kentucky and composters in Washington State have been working on their garbage-to-fuel conversion techniques, and the company Waste Management already liquifies landfill gas to fuel trucks, according to auto industry analysts at Edmunds.

Animal Fat - Alternative Fuel
Chicken producer Tyson actually has a renewable energy arm and through partnerships with ConocoPhillips and Syntroleum, the company is working on creating fuel out of fat, oil and grease.
Because of the economic downturn, ConocoPhillips halted its attempts to create ultra-low sulfur diesel out of animal fat in 2008, the company says.
But the Department of Energy’s research facility at the Brookhaven National Laboratory is using fuels made from turkey waste, according to the government agency.

Sawdust - Alternative Fuel
The lumber industry generates a lot of waste — thousands of tons per year, according to Edmunds — and sawdust and wood chips can be used to make cellulosic ethanol which cars can run on.
Earlier this year, oil refiner Valero Energy teamed up with Frontier Renewable Resources the first commercial scale wood-based cellulosic ethanol bio-refineries.

Corn - Alternative Fuel
Corn is already being used as a fuel alternative in E85 ethanol, which flex-fuel engines run on.
But earlier this year, scientists found that using too much fertilizer to grow corn affects the stalks and leaves, making ethanol extraction more difficult, according to the American Chemical Society.
