A typical electric vehicle charges from your electric outlet, and therefore, from the powerplant at the other end of that wire.
*
Powerplants burn a variety of fuels, including coal, natural gas, hydroelectric, wind, solar, and nuclear.
*
The power grid is about 95% efficient in getting the electricity to the car. Modern battery systems are about 88% efficient in storing it. Electric propulsion systems are about 95% efficient in using the energy to move the car. Electric motors also don't have to idle at stoplights, and reclaim braking energy for re-use.
*
This makes electric cars much more efficient than gas cars, which have gasoline engines that are only 25% efficient. And a lot of that energy is wasted idling and braking. Gasoline also has inefficiencies, since it takes lots of electricity to refine it, and more energy is wasted trucking the final product to your local gas station.
*
Most electric cars get 4 to 5 miles per kilowatt-hour. A kilowatt-hour costs as little as 2 cents in some places, and as much as 20 cents in others. So the cost per mile in an EV runs from half-a-cent up to about 5 cents per mile. In most places, it will cost from 1 to 2 cents per mile. Gasoline, for comparison, is closer to 10 cents per mile and climbing.

risky nuclear power? Nuclear power is statistically safer than wind power it is between the failings you probably like (yet nevertheless, you in basic terms look to love ineffective power components). the explanation that they are needing secure nuclear power is with the help of the fact nuclear power is the only sparkling power source which could actual furnish each and all the electrical powered energy desires of a rustic (look at how badly wind has failed in Denmark and how many coal power flowers Germany is construction because of the fact wind and image voltaic are not okay to run a power grid). They have been very plenty compelled into nuclear because of the fact it is the only element which could do the activity required, if image voltaic and wind had even a faint desire of having the flexibility to take over from fossil fuels and the previous nuclear power flowers that are going to be decommissioned quickly then that's what they had be doing. Now in case you have chose to alter over to image voltaic and wind you could need huge technological advancements in power storage technologies to be able to handle the unreliability. at the instant they take care of the unreliability of those 2 power components by having organic gasoline fired turbines lower back them up because of the fact of this they're in part fossil gasoline and subsequently no longer in any way environmentally friendly. Nuclear fission OTOH does not elect any technological advancements to be potential, France have been given to approximately 80% nuclear using final era reactors and emit almost no CO2 while producing their electrical energy.
