There was a time that everyone went out to buy diesel engine vehicles, because gas was more expensive than diesel fuel. Today, with almost all fuel prices climbing rapidly, people are not exactly sure what to do. These days, diesel energy prices are more expensive than regular gasoline. Since not everybody really knows what the prices are going to do, scientists, environmentalists, and technologists are all seeking a better alternative to fossil fuels.

After the diesel engine originally premiered it was supposed to run on peanut oil or vegetable seed oil, but with cheap petroleum prices, people just used diesel fuel. As a result, many people have forgotten that diesel cars can easily be powered by natural cooking oils. Nowadays, biodiesel fuels are being developed by using soybean oil, vegetable oil, animal fats and old restaurant grease. There is a blend referred to as B20 which is 80% petroleum diesel and 20% biodiesel. What really is nice about biodiesel is the fact that fuel is biodegradable plus it gives out low gas emissions.

One more solution is a fuel that is a byproduct of petroleum refining called liquefied petroleum gas or LPG, which may be used in place of diesel fuel. Of all of the petroleum products, LPG may be the cheapest, and at its normal temperature and pressure it contains hydrocarbons and vapor. By using a conversion package, LPG, which is mainly propane, can be used as an alternative fuel, and it is widely available. Another biodegradable and renewable energy resource is ethanol. This gas burns cleanly which means that it does not give off greenhouse gases. It happens to be made from 15% gasoline and 85% alcohol, which is how it got the name E85, and it can be used on any diesel engine vehicle. It does have a higher price tag than any other alternative type of fuel.

Another solution is electric cars but there are a few issues. The battery doesn’t last very long and cannot go fast enough for the freeway. Tesla is in fact the very first sports car that runs on total electricity and it has put to rest the two issues. Regardless of the excellent improvement in electric cars, they have not sold well because of the high prices. If people aren’t willing to go electric, at least buying a hybrid is the next best thing. These types of cars run on both gasoline as well as electricity. Though these kinds of cars cost more than regular fuel cars, they provide more savings in the long term.

You will find positives and negatives for all of the different fuels. But efforts are moving forward to improve and to make them more practical for the consumer market. Down the road, all cars are going to be using fuel aside from gasoline.
