Commercial and economic comparison of traditional and alternative fuels

Negative predictions about oil stocks combined with the instability in the Middle East encourage development of alternative fuels, which would reduce dependence of the world's economies on oil. The oil and petroleum derivatives are the main dependencies for vehicular traffic, which contributes to the greenhouse gas emissions by a large part. It is therefore necessary to focus on trying to reduce the fuel consumption of cars used for personal transportation. One way to achieve this goal is, for example, to convert existing cars to run on biofuels, buying a hybrid or an electronic vehicle, or, hopefully soon, hydrogen-powered automobile. Obstacles preventing a wider deployment of such fuels and drive systems are often higher purchase and operating costs. These economic disadvantages are being gradually reduced though, and in the future we can surely expect an increase in the number of alternative vehicles on the roads.
