Is an alternative of fuel can help stopping global warming?

Hello Friends, While watching discovery channel I thought this question, and I was just wondering about it. People are thinking of electric vehicles, which can be an alternative of fossil fuel and reduce pollution, which can help reduce global warming. However, if you think deeply from where this electricity comes from? Almost from coals or radioactivity! This is a basic source of pollution. By looking at this, what do you think is this a real alternative of our problems? Please reply to this question. I will be glad to see the replies from all of the wonderful users and thankful to Yahoo! Answers.

1. hydrogen fuel cells. These will not only stop pollution but will restore the atmosphere.
2. The production of CO2 is not a pollutant . The plants take in the CO2 and give us back the oxygen and keeps the C . CO2 is the first part of mother natures air recycling . If CO2 is so bad the only real solution is to stop breathing ,but thanks to God he has already taken care of it.
3. Any system that doesn't produce a green house gas or too much water vapor will work to help reduce global warming. To Johnnie: The problem is that there is not enough cholorphyll phototrophic lifeforms to take up all the CO2 being emitted. So, it slowly building up in the atmosphere.
4. ---------- Electric cars produce much less pollution than gas cars, because of the greater efficiency of electric drive (electric motor, 95% efficient, versus gas engine, 25% efficient.) Delivering energy by wire to electric cars (95% efficient) is also much, much more efficient than trucking gas to thousands of service stations. Fuel is also burned far more efficiently in large power stations (up to 85% efficient) than it could ever be used in your car. * The proof of all this is right in the fuel prices. Gasoline costs at least 10 cents per mile. Electric cars drive around for only a penny or two per mile. The difference comes from efficiency. Much greater efficiency = much less pollution. * Believe it or not, your gas car uses electricity. It's true, large amounts of electricity are used to refine gasoline. Gasoline makes pollution during refining, it makes pollution when it's being delivered to gas stations, and it makes pollution when you use it. Anything else is an improvement. * Incidentally, hydrogen fuel-cell cars are also electric cars, including batteries, which are needed for acceleration. But they are less efficient than battery-powered cars, because of the extra electricity required to extract the hydrogen, and the wasted energy of transporting hydrogen to service stations. Also, fuel cell vehicles will always be more expensive than pure electric cars, because they are electric cars with a fuel cell added on. * Rather than adding fuel cells to electric cars, it makes more sense to add solar panels. Then, both the cost per mile and the pollution is reduced to ZERO. No other automotive fuel system can say this. * Even if you don't want to charge from solar panels - it doesn't matter if powerplants burn dirty fuel, because EVs are far more efficient than gas cars, therefore much less pollution per mile.

5. well there working on cars that run on water and even air global warming will happen any way but we are making it happen faster and worse
6. Ethanol fuel is a biofuel alternative to gasoline. Anhydrous ethanol can be blended with gasoline in varying quantities to reduce consumption of petroleum fuels and in attempts to reduce air pollution. It can be produced from a variety of feedstocks like sugar cane, sunflower, whey, corn, grain, wheat, etc.. It won't make a huge impact, but it does produce less poluntants than regular gasoline alone. **************** As for electrical cars... You would have to make cleaner electricity production first if the power plant supplying the energy to your car is the issue. We would have to switch over to water power, solar power, wind power, etc. If you have a clean source of power, than your car would be powered up by clean energy sources, thus reducing even more polutants.
