<br/><br/><br/>There are lots of people who are tired of the ever-increasing gas prices but feel unable to do anything about it. Those that can afford it are getting new, fuel-efficient vehicles in an effort to control their gas spending. It wasn't that long ago that oil prices went up globally. We will examine the alternative choices we have for gasoline.<br/><br/>Alternative fuel is essentially fuel that is not gas or diesel. Vehicle have recently been utilizing electricity, solar energy and hybrid, which is a mix of gasoline and electric. There are even options for water to run with gas to help save on fuel. Governments around the world are encouraging car makers to produce these alternative fuels autos for several reasons. In Europe, the environmental laws have become stricter and taxes have been levied fuel so there was no choice for car producers. There are even stricter restrictions coming out involving greenhouse gas emissions.<br/><br/>Our atmosphere is getting worse due to the greenhouse gases being emitted by fossil fueled autos. Because of this, we are experiencing global warming at a monumental scale. It's tough to believe that there are cars that are running on fuel cells, solar power, ethanol, and hydrogen. Vehicles that run on LPG, or liquified petroleum gas, are being fueled by a mixture of butane and propane. When compressed, its hydrocarbon gases become liquid. This fuel not only provides cleaner emissions but it reduces fuel expenses too.<br/><br/>Automobiles that use energy from the sun can either produce electricity to run the motor or use it to produce hydrogen. The solar batteries are typically on the roof of the car. Other autos use ethanol, which originates from plants. Plants high in carbohydrates or sugar are fermented to make alcohol. In Brazil, they have been able to replace more than 200,000 barrels of crude oil daily with ethanol fuel based on sugar cane. They have decreased their toxic emissions by no less than 30% with their ethanol powered cars. There is another type of vehicle that uses fuel cells, which generate electricity and heat out of hydrogen and oxygen. These type of autos are the best to run, as they only give off water vapor and heat.<br/><br/>In the case of hybrid automobiles, like the Toyota Prius, they use a number of sources of energy. The advanced technology they use fuses an electric motor with a small gas engine. Each and every part is used differently depending on driving situation. The battery is charged while fuel and electricity are used on the state highway. The exploration of alternative fuel sources is vital to finding a solution to our environmental issues and economic issues.
