Alternative sources of fuel for cars may be too little too late, but they are certainly better than nothing. In many cities all across the nation, alternative fuel sources are becoming increasingly popular, as people begin to plan for what looks to be a bleak energy future. The importance of alternative fuel sources can not be overrated. We have reached the half way point for oil consumption, and from here on in, it will get more and more expensive to extract smaller and smaller amounts of oil, resulting in the end of fossil fuel use. The sooner we switch to alternative fuel sources, the better, but it seems that our economy is so completely dependent on gasoline that switching might not be enough to save us now.

Solar is a really useful alternative fuel source which will always be available. Although solar power is not one of the alternative fuel sources for cars, it is a great source of power for houses. A few solar panels can provide all of the heating needed for the water tanks, and for the house as well. It is even possible for a house to become completely powered by alternative fuel sources, although this is still often an expensive option.

Alternate fuel sources for cares are varied. Hybrid cars, although technically not using alternative fuel sources, have found ways to make gas consumption much more efficient. These vehicles can get 50 miles per gallon or more out of conventional fuel! This is, in my opinion, better than alternative fuel sources which involve the inefficient burning of vegetable oil. Biodeisel, and ethanol powered cars, while eliminating our dependence on oil through using alternative fuel sources, still pollute the environment with their smoke. Does it make sense to switch to an alternative fuel source which does every bit as much to pollute as the one which we were using before it? It sure does not make sense to me!

Two of the most promising alternative fuel sources are electricity and hydrogen. These alternative fuel sources are actually closely related; hydrogen is a highly efficient way to store power which can be then converted into electricity in the car. This alleviates the need for huge, bulky, heavy batteries. The car can be lighter, which means that it can be more efficient and easier to maintain. If these alternative fuel sources are perfected, they might form the best solution to all of our fuel problems.
