The depletion of our nonrenewable sources has been a problem ever since cars became a major asset to our daily lives. The effect of cars on our environment is a major problem as well because it destroys the Earth’s Ozone layer which keeps the planet at a safe temperature. Over the years scientists have found multiple ways to cope with these problems. The three main solutions to slow down gasoline usage is the use of ethanol, hybrid cars, and hydrogen. Each of these three alternatives has their pros and cons. This paper will discuss how each is made, how the fuel works, and their pros and cons. The first and most popular type of alternative fuel is called ethanol. Ethanol is the alcohol which is made from mainly corn. (Kanellos) Ethanol is usually mixed with gasoline to make fuel. When this is made the fuel gets special names. Each fuel is called E then a number following it. The number following the E indicates what percentage of ethanol is contained in the gas. The amount of ethanol ranges from 5 – 85 percent. Ethanol is made by using cornstarch powder and heating it to 225 degrees. It is then cooled and purified. Then a small amount of gasoline is added to make the fuel acceptable for cars. This newly created fuel is then transported to gas stations.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
