So when gas vehicles are banned and everything runs on electricity we will all be greener?
So when gas vehicles are banned and everything runs on electricity we will all be greener.
That statement is hilarious. Environmentalists think that switching to electricity cars will save the planet and be cleaner, but do they leave out of the equation where that electricity is coming from?
If everyone drives an electric car, electricity needs would skyrocket.
And environmentalists think that wind power and solar power can support this??????
Wind power produces such little electricity a large wind farm couldn't power a small town...

If we hook turbines to the hot air the Democrat Marxists are spewing we could tap a perpetual energy source.

The premise of this question, that all gas vehicles will be suddenly banned, and everyone will suddenly drive electric cars, is unreasonable.
But you are right in the sense that eventually, nature itself will ban us from using gasoline - oil supplies will dwindle, and gas will be more expensive than the next best alternative. That might be electric, it might be biodiesel, it might be natural gas (temporarily).
On an individual basis, and electric car actually is cleaner than a gasoline one, even if the electricity came from a coal-burning plant. The reason there isn't more widespread adoption is price to the consumer.
As for skyrocketing electric demand, that would be partially true, and partially not. As the earth gets more crowded, there are less resources per person. Europe has been economizing on electricity and resources for some time, now. They conserve much better than the US does, and use public transportation more.
In 1900, someone might have argued that it would be impossible to generate enough reliable electric energy to light every house in America, and they would have been right, for the time being. Similarly, there are technical problems to solve to harvest enough solar to charge electric cars, but there is nothing in physics to preclude it. Enough energy is there. Having a battery in the car actually helps, because it can accept a bursty charge, and does not require that the solar produce steady power 24/7.

At this point in time about 80% of all US electricity is produced by coal power plants with a few dams thrown in and even fewer nuclear plants.
The electricity produced by wind mills and solar power is inconsequential in the scheme of things and will remain so until situations like MA where the liberal people of MA fought tooth and nail to prevent wind mills from being put up TEN miles off the coast because it would "ruin the few".
Pollution from electricity production is something it seems many environmentalist have not considered and or the impact on the cost to citizens. US electric production would have to increase drastically to cover charging thousands upon thousands of electric cars beyond what they are capable of today.

Everyone who makes this point forgets something very important - gasoline is extremely inefficient. Take a look just at the process for making and distributing gasoline.
It takes about 6 kilowatt-hours of energy to refine a single gallon of gasoline. If you just put that electricity into an electric car, you could drive 20 to 30 miles - without even bothering to make any gasoline! So, just like the EV driver, you are using electricity to drive. Unlike the EV driver, you are burning petroleum at the same time.
The same point applies to fuel distribution. The last step for EVs is sending energy via wire to charge the car (grid electricity transport is about 93 - 97% efficient.)
Compare this to gasoline distribution - the last step is distributing gasoline via a fleet of trucks to thousands of service stations. Does that sound efficient to you?
And finally, the final step - driving the car. Gasoline burns in an inefficient gasoline engine. Gas engines are about 25% efficient ideally - and only about 15% efficient in traffic (because of braking and idling losses.)
Contrast this to an electric motor - which is about 90% efficient, doesn't need to idle, and recovers braking energy.
All of the above is why driving on electricity only costs about 2 to 3 cents per mile. Gasoline costs five times as much. Electricity is cheaper and cleaner because EVs are many times more efficient.

Wind and solar are not viable alternatives. BOTH of them require a power plant be running at all time in order to take up the slack as well as when there is no wind or sun light, let alone the massively higher costs in producing them. Just look to Solyndra for an example, $530 million in tax dollars down the tube.
And just try to get a permit for hydro dam!

No, everything running on electricity won't make everything greener. But it will remove America's dependency on oil from countries that hate us. It will also make the vehicles independent of the source of energy. Tomorrow if electricity is made from nuclear fusion, you won't need to change your car again.
Electricity can be created from nuclear, hydro and many other sources other than coal. Though today it is Coal.

Liberals can't figure out that their own agenda is against electricity production. They hate coal because of the crap it pumps into the air, they hate nuclear because they hate nukes, they hate wind because it makes noise and it takes splurpy, drippy petroleum to lubricate those big windmills, they hate solar because it fvcks up the view...
What is the answer? Do liberals want us all to live like the Amish, or what?

Exactly. Electricity comes mostly from coal. Coal gives off pollution. Ergo, electric cars are a joke.
