Is an alternative of fuel can help stopping global warming?

Question

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.

----------
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. See the link below for more info.

Answer 2

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.

buearucratic greed. why disrupt a nations infrastructure and energy grid with biologically sound and safe energy sources that will last longer than our nation when you can make a million bucks a day selling imported oil to consumers that are already trained to commute to work far from home? why should a politician or city planner work toward a new energy system that will likely not be in place in his lifetime, if there is an oil lobby waiting in the wings to give him enough money to live comfortably for the rest of his life if he stops going forward with plans that wouldn't include thier product? the amount of money needed to convert our nation to passive energy sources is beyond comprehension. its almost as if our entire energy grid would have to be ripped out and redone, can you imagine the uproar that comsumers would make during the power losses that redoing the grid would make? even if they wanted the change they would protest the process. no one wants to live on a potholed street, but bitterly complain about the traffic jams and mess and expense that repairing the street takes while it happens, even though they are happy when its done. we want the results, not the inconviences that happen while getting them. we want to stop dependaency on foriegn oil and harmful energy practices now, but don't want to go through the effort of getting that result. as a people we are spoiled and lazy. we want instant gratification, not huge tax increases, work, and hassle to get it. did you know that there is technology available right now that can put super solar collectors in the desert (nevada i think) that can use solar power (a potentially neverending supply, at least until the sun blows up, but we as a race will likely never see that happening) to power our entire NATIONs needs for its forseeable future? yes, all 48 intercontinental states, for ALL our current and forseeable energy needs (at least in our homes and businesses anyway) powered by the sun. they would have to cover 1/3 of the desert, but it can be done. right now. whats stopping it is money. a phenominal mountain of money. when you are faced with the changes that would best be made for the nation, but the changes are so vast and encompassing, where do you start? i think that small towns would be best, to begin building an infratructure to allow passive energy delivery, perhaps while they fix those broken streets. maybe even bury those hideous telephone and electric lines too, in a clean well lit (solar fiber optics!) tunnel system similar to a sewer system where all pipes and energy lines can be accessed underground, under the streets where the weather cannot damage them nor prevent work. i think its the small towns that will have to take up the torch to turn our nation green. the small towns don't have as much to fight against (fat cat mayors, money hungry politicians, a bloated government fed on bribes and oil kickbacks). if they can provide a good example of how beneficial green energy can be, and if the next generation of politicians are raised in these towns, perhaps our backward nation can finally begin to move forward to showing the world that we don't have to be the leading oil users, but the leading green producers instead. the current generation is growing up more aware of the environment and are trying to take action. lets hope they aren't as swayed by the mighty dollar as our forebears have been. it must start somewhere, a trip of a thousand miles starts with one small step. changing the nations infrastructure can start with one small town.

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.

Answer 5

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.

Answer 6

hydrogen fuel cells. These will not only stop pollution but will restore the atmosphere.

Answer 7

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
