With the depletion of the traditional fuel sources, the alternate fuel sources available nowadays become more and more important. Although there are lots of different fuel sources, gas for example is nearly out, so the more we use any alternate fuel source the better it is both for environment and for our fellow men. Extracting the gasoline pollutions is already too expensive and in addition its supplies are almost exhausted, however there are alternate fuel sources. And in case we plan their consumption effectively they will soon take the place of the traditional ones, maybe even before the time when the crisis will come.
A lot of the alternate fuel sources are actually being extracted from different kinds of plants. And this is much better because these resources are at least partly renewable. There is such an alternate fuel source called E85 or biodiesel. It actually consists of 85% ethanol and 15% gasoline and even not totally renewable it is still a lot better than burning only gas. Unfortunately those alternate fuel sources are not the best solution. Yes, they do pollute less than traditional fuel sources and have some other advantages - chiefly that they are renewable, but actually they still do pollute and in addition they require growing of such vast amounts of corn, that it means a lot less land left to feed people from.
One of the best alternate fuel sources is electricity. Electric cars are very efficient because all the electrical power that they need is being produced in one location situated centrally, instead of a small and inefficient combustion motor situated internally. The electric cars use electricity, no matter how and where it was generated. It can be coming from any power plant be it a wind, a hydro-electric or a coal one. That makes such cars really good alternate means of transportation. There is another alternate fuel source and that one is actually the best. It consists of your own two legs on the pedals of a bike.
It has actually become unexpectedly popular option lately, as the other alternatives still haven't proved to be successful. Biodiesels availability is very limited and electromobiles are still not in serial production, while the bike is already a widely spread, perfectly working machine, suitable for both short and medium commutes. Unlike the more expensive alternatives, walking or riding your bike to your destination will simultaneously maintain your figure and keep you fit, save you some money and of course will help to protect the environment as well.
