Will electric cars help......?

Question

Will electric cars help in the fight against pollution and reduce our need for oil?

Answer 1

Yes, electric cars are great we need them as well as concentrating solar. Electric Trains would be great as well as electric plains.

Answer 2

battery acid spots instead of oil spots in the parking lot

Answer 3

YES!!!!!!!!!!

IT WOULD!!!!!!!!

WHO KILLED THE ELECTIC CAR!!!!!!!

BEST DOCUMENTARY EVER!!!!!!!!

Answer 4

Actual electric cars can certainly help, hybrids that only run on gasoline don't help much at all.  As several pointed out, hybrids like the Prius don't get that much better as mileage than conventional cars.  Keep in mind hybrids aren't electric cars so don't use them as an example of electric cars.  True electric cars don't have gas tanks at all.  I have been driving electric cars since 1990.  They do work and they don't use gas at all.

Answer 5

Electric and hydrogen have the same problem: They're not net energy sources. So whether they are clean or not depends on how they're generated. Use clean energy, they're clean. Use fossil fuels, they're dirty. Simple as that.

Answer 6

Yes, it will help very little.

Answer 7

Only in the fact they are subject to  and guide  many of us to the use of hydrogen as the primary fuel supply.  We have the tech in place to make this the preffered fuel. To ignore this is a'kin to giving all your money to the oil industry to hedge your savings/retirement portfolio. Sorry to inform you that you have made a poor choice with a bankrupt return..

Answer 8

Absolutely.  Just for starters, electric cars are much more efficient than internal combustion engine cars.  On top of that, it's much easier to clean up a small number of power plants than millions of individual car emissions.  Plus our power grid depends on things like coal, nuclear, and renewables, not on oil.

So yes, electric cars will help in the fight against pollution and reduce our need for oil.

Answer 9

it will but the inverntor of that will be murdured bec he's making all these oil companies go bankrupt

Answer 10

IF they can get the range over 100 miles and of course if you could charge them with solar power or non gridded power that is what scares the h**l out of the energy companies, suddenly they just lost control.

Answer 11

Supposedly, but now they're saying that they use a lot of water so for areas of the country like the southwest and southeast that are experiencing a water shortage, that is an issue.  You can't win for losing it seems.

Answer 12

Properly operating electric vehicles are about 80% efficient from plug to wheel.  Petrol combustion vehicles are about 20% (hybrids about 25%) tank-to-wheel.  Now, well-to-tank, we get about 83% efficiency to make the gasoline/diesel.  For power generation, we CAN get around  60% efficiency, well-to-plug, but the current grid is only about 30%.

IC: 0.83*0.20 = 16% well-to-wheel

HY: 0.83*0.25 = 21% well-to-wheel

EC: 0.30*0.80 = 24% well-to-wheel

EEC: 0.60*0.80 = 48% well-to-wheel

So, comparing something like a Civic to an Electric Civic charged from the modern grid, the Civic would get about 40 mpg while the electric would get about 60 mpg equivalent.  Of course, with electricity coming from ever more efficient and varied sources, the electric only gets better (up to 120 mpg equivalent).

So, if everyone switched to electrics today, and we used the oil to make electricity in efficient new plants, we could cut oil usage in the US by 33%.  Even using hybrids would cut it by 15% (plug-in hybrids even better).  That is a sizable amount, in terms of both gaining energy independence and abating anthropogenic global warming.  As we get greener electricity production, the story gets even better.

Answer 13

have you checked out the mileage of the Prius?

it has to be electric to do that.

it does that by using electric braking when stopping.

you'll note that it's city mileage is higher than it's highway mileage.

that only happens because of electric braking.

so yes, clearly they will help.

clearly, if we use coal to generate electricity to charge the battery, that wouldn't be great.

however, if you use solar cells on top of your house, or wind energy, that would make quite a large difference.

Answer 14

no the new electric cars get the same gas mileage as a vw bug so it really does not help in the fight against global warming

Answer 15

of course it will help fight against pollution, but it is but a number of a massive number of other problems that need to be addressed also, such as fossil fuels burnt to supply electricity to those cars, once we find an alternative power source, that is clean and renewable, then we can say that electric cars will help dually with the eradication of fossil fuel use

Answer 16

It all depends.

The best thing about electric vehicles is that it is the only TRUE flex fuel vehicle. For example, you can't have a nuclear car. But, you can have a nuclear power plant connected to a car (charged overnight), thus, no CO2 emmisions, if that is your definition of pollution. Waste from nuclear power plants is a different topic.

Likewise, if the only source for the cars' energy is fossil fuel, then the answer would be no, most likely not.

To completely environmental, many who plan to own EV's also plan on installing solar cells or wind turbines on their houses, therefore reducing all environmental harm.

Answer 17

A lot of electricity comes from fossil fuel, so no.
