Electricity is geting expensive too, not like petrolium, but electricity is not the best fuel alternative for powering automobiles in my opinion...Infact most of the electric producing plants here in the US are not invironment friendly..They omit....Unless the electricity is being created by solar means and or by wind or water flow I think electric cars are a bit misleading for the masses..
the benefits of an electric car, enegetically talking. Are that there is very little loss of energy in all the process of moving the car.
in a combustion engine, a LOT of energy goes in heat, in an electric car, very little energy goes in heat generated by the electric motor.
Also, when you brake with an electric, car, you get a lot of energy back to the source, again, not lost in heat generated by the brakes. That's where all the economy comes from. I know in USA the electricity cost a lot of money, not like here, and most also comes from coal/gas plants and nuclear power plants, wich are very pollutive ( coal ).
Here, 98% of our energy comes from those waterfalls, clean, efficient, cost nothing to produce energy, and little maintain costs. But, our politicians are so dumb and retarded, that now we have a lot of trouble to substain our own demand, and buy some electricity from the states on very cold winter days.
20 years ago, we were the "arabs of the electricity" and now... nothing more.
anyway, this gets a little off topic. But an electric car is a lot more environnementally friendly for the planet. Yes, the electricity it needs comes from pollutive power plants, but compare the pollution generated by the plant, for your single charge 250km trip, VS all the gas you used for your 250km trip (about 30 liters of gas!!!)
with 30 liters of gas in a power plant, you could have produced at least 10 times the electricity your electric car would have needed to do the same trip. (speculations, it might be a lot more energy produced!) Also the noise pollution, and no emissions are very appreciated in heavy cities. a car idling won't be very efficient against smog since the exausth system can't keep heated enough. The catalitic converters can't do their job perfectly.
the electric cars are not perfect, but they are a veeeeery big step front of now. And since most of people don't even drive 250km in a day, everyone could use an electric car for our daily commute.
