<br/> <br/> <br/><br/><br/>A lot of people are sick of gasoline prices, but have no idea as to what to do about it. Those that can afford it are getting new, fuel-efficient autos in an effort to control their gas spending. It wasn't too long ago that prices started to soar for gas. We will look to see what alternative options we have for gasoline.<br/><br/>When you talk about alternative fuel, you are in essence talking about any fuel other than gas or diesel. Vehicle have recently been using electric power, solar energy and hybrid, which is a mix of petrol and electric. These days there are even cars that run on water-to-gas technology, which means they are able to supplement their gas by using water. There are reasons why many car companies are making the effort to produce vehicles that use alternative fuels. Europe has tightened the environmental laws, and imposed taxes on fuel, so car makers had to take action. There are even stricter regulations coming out regarding greenhouse gas emissions.<br/><br/>Our atmosphere is becoming worse as a result of the greenhouse gases being given off by fossil fueled automobiles. As a result, we are experiencing global warming at an epic scale. There are automobiles today that are running on hydrogen, LPG, solar power and fuel cells. LPG is liquified petroleum gas, and vehicles running on it are running on a combination of butane and propane. When compressed, they become hydrocarbon gases that turn to liquid. Not only will cars running on this cut back on their carbon monoxide emission, but cut fuel expense in half compared to diesel and gas.<br/><br/>There are vehicles that use solar batteries to produce electricity out of the sunlight, and then use the electricity to run an electric motor, or generate another fuel like hydrogen. The solar arrays are set up on the roof of the vehicles. Some cars use fuels like ethanol which is sourced from plants. The fuel is created when plants or crops that are high in sugar or carbohydrates are fermented. In Brazil, sugar cane-based ethanol has replaced roughly 200,000 barrels of fossil oil daily. Deadly emissions in this country have gone down more than 30% because of ethanol powered vehicles. Another type of auto uses fuel cells which makes electricity and heat from oxygen and hydrogen. These vehicles are extremely clean because they produce water vapor and heat.<br/><br/>Hybrid cars, such as the Toyota Prius, use a few different energy sources. The advanced technology they employ combines an electric motor with a small gasoline engine. The fuel types are used alternately according the driving situation. The battery is charged while fuel and electricity are used on the superhighway. Solving environmental issues is the purpose of adapting to more expensive fuel costs by looking int alternative sources for energy.
