Alternative Fuels for Cars 1st December 2014 Cars are major polluters in our society, they omit fossil fuels into the air and considering we are highly dependent on our cars running and every day we use them. So you think every household in the UK (25,691,000 households in the UK) and there is 1.1 cars per those households on average. The amount is around 28,260,100. On a global scale for instance America and Russia you think there are way more than the amount of cars in our country releasing these fossil fuels into the air. Around 1/7th of the world use cars. Biodiesel is an alternative fuel based on vegetable oils or animal fats, even those recycled after restaurants have used them for cooking. Vehicle engines can be converted to burn biodiesel in its pure form, and biodiesel can also be blended with petroleum diesel and used in unmodified engines. Positive: Biodiesel is safe, biodegradable, reduces air pollutants associated with vehicle emissions, such as particulate matter, carbon monoxide and hydrocarbons. Negative: Limited production and distribution infrastructure. Electricity can be used as a transportation alternative fuel for battery-powered electric and fuel-cell vehicles. Battery powered electric vehicles store power in batteries that are recharged by plugging the vehicle into a standard electrical source. Positive: Electricity for transportation is highly efficient, and we already have an extensive electricity network. Negative: Much electricity is generated today from coal or natural gas, leaving a bad carbon footprint. (Nonetheless, electric vehicles are still the greenest option around when it comes to cars.) Hydrogen can be mixed with natural gas to create an alternative fuel for vehicles that use certain types of internal combustion engines. Hydrogen is also used in fuel-cell vehicles that run on electricity produced by the petrochemical reaction that occurs when hydrogen and oxygen are combined in the fuel “stack.” Positive: No bad emissions. Negative: Cost. And also the lack of fueling infrastructure and difficulty of putting it in place. There are just a few examples of alternative fuels, you need to begin to use them as our world, our homes and our planets may come under great danger if we don't make a change. It is important too because fossil fuels are running out. They help us make electricity, so if you save fossil fuels enough, as at the minute fossil fuels could be gone in the next 20 years, they will last much longer and our alternative fuels will come into much greater need and use. Some of them there are vast supplies of. Elg - T 2020 Source: http://en.wikipedia.org/wiki/Alternative_fuel
