I have been deep into alternative fuels and fuel enhancers to extend the mileage on gasoline and diesel engines. I even bought a cheap car to experiment on myself.
I have come to realize that electric powered cars are feasible but not with the technology many auto manufacturers are using as recharging is largely dependant upon the current electric grid. When electricity is made at the power plants, there is possibly the expulsion of just as much anti-green emissions as there is with ordinary gasoline or diesel. As of now, the cost associated with recharging the batteries on an electric car may be less than powering the car with gasoline but what about the future? What about the cost of these electric cars? $50,000-$100,000 for one of these cars make purchasing one of them out of reach of many in the population of the world, especially when you consider that trade-in values of their old car is likely to be deminished or nill.
On-going research in electric powered vehicles is very important to continue but with a different twist from using the electric grid for recharging. Some sort of on-board electricity generating capability, like fuel cells and such, must be incorporated into the car for them to be truly feasible. Such vehicles are being built on a research scale but are currently (and for the foreseeable future) very cost prohibitive.
Alcohol, methanol and hydrogen powered vehicles are sure to be the next big push because these fuels can be used in the current engines with only a little modification. This would put these alternative fuels within the scope of use for everyone without necessarily replacing their car or truck.
I think the most exciting prospect is hydrogen. The by-products of burning hydrogen are harmless to the atmosphere and hydrogen is one of, if not the, most abundant element on our planet. Hydrogen powered vehicles, using ordinary current production internal combustion engines, have been and are continuing to be developed. There are thousands of people involved in these vehicles in one capacity or the other. Hydrogen boosted large diesel engines is reportedly possible with fuel mileages that are dramatically enhanced. Environmentally detrimental emissions from hydrogen boosted engines are reportedly reduced more too.
Some good websites where you can learn more are appearing or are gaining recognition (I don't in any way endorse any websites on these subjects because I need to see successful results instead of reading about successful results-but then again, how do you see if you don't first learn?). For example, very good research material for purchase can be found at www.knowledgepublications.com/ , just be careful of your purchases (in other words, don't get buy crazy and buy something you don't need). If you go at it with the mindset of learning about things such as alcohol, hydrogen, solar, etc. instead of an overnite miracle fuel for the gasoline/diesel price crunch we are currently experiencing, this is a good starting point. If you go at it with any motive other than learning, you will likely be dissappointed because some of these things are still in the infant stages.
If my own research turns up something worthy of passing along to you, I will post it or even write an ebook about it and offer it on this site. You can rest assured that anything I write about will be as genuine and true as I know how to make it.
