Basically, my arguement is ‘Alternative fuels need to be researched for motor vehicles because they have many advantages.’ I choose this arguement because in many sources there are so many things about vehicles when individuals think about alternative fuels.(Emissions etc.) I will introduce alternative fuels firstly(there are many of them for example, biodisel), then i will briefly compare normal fuels emissions with alternative fuel emisions. To put it other words, i will state environmental advantages of alternative fuels. Consequently, people’s ideas need to be stated about alternative fuels because ideas of people can be used as proofs. (advantages of alternative fuels) Then economic facts of alternative fuels need to be stated. The most problematic part of the arguement is i think this part because alternative fuels can be cheaper than other fuels but their mechanical systems requires more expensive parts so they have both advantages and disadvantages. I will be focused on advantages.
