Although most cars are powered by gasoline, there are a few different types of alternative fuel options that are currently on the market; if they are not on the market, then they are in the works. Alternative fuel vehicles are those that use other means of power and energy to run a vehicle other than gasoline. This is actually a great concept as these other types of vehicles tend to have less emissions which decreases greenhouse gases, and they overall have long term benefits on the environment. Most of the alternative fuel options with decrease deforestation, pollution, and the rate of biodegradation in the environment.
