The rising prices of gasoline and how many miles per gallon a vehicle can achieve are large concerns for today’s drivers. Automobile owners are also reconsidering the impacts of the pollution their vehicles are having on our environment. Automobile manufacturers have been scrambling for more fuel-efficient engines and diving into the development of alternatively fueled vehicles. People are trading in their old gas-guzzling cars for newer more efficient ones. Taking all of these statements into consideration, alternative fuels and when we will begin to use them on a larger scale have become a topic of discussion around the world.
