HOW MUCH WILL IT COST TO RECHARGE AN ELECTRIC CAR EIGHT HOURS A NIGHT FOR ONE MONTH WITH A 220V PLUG??

Of course these calculations are only approximations but they would not be more than 5% or so adrift from reality. Have a look here for more on the calculating front… http://www.evconvert.com/tools/evcalc/ … all the blue bits of text expand to give you more info or allow you to tweak things. It doesn’t really matter what variables you stick in – just look at the amount of power required to do 50 mph compared with 70mph for any given gear. If you need some real gear ratios, have a look here… http://www.evalbum.com/2092. MW

If coal can be mined and burned cleaner at centralized power plants, and distributed through power lines compared to pumping oil refining it, shipping and burning in separate cars, then so be it. But if we only do that, we have not done enough. Compared to oil, coal burning also contributed large amounts of other pollutants to the environment, including radioactive elements.

We need to get off of both oil and coal as soon as possible, and before then, we should at least factor in the total cost of using either of these non-renewable energy resources including all the production costs, and including the cost of completely cleaning up all the pollution produced.

Is it a step in the right direction to promote electric vehicles even if we require building more coal power plants? Maybe so, if it means we are cleaner and more efficient overall, and especially so because electricity can later be produced by renewable resources. Electric vehicle battery recharging in off-peak hours also helps balance out power demands throughout the day. Also consider the uneven availability of solar and wind energy – the excess supply can be stored in spare batteries for use later.

Notice no one discusses how much energy is used to refine crude oil into gasoline?

It takes about 140kWh of natural gas and electricity to refine ONE 42 gallon barrel of crude oil into 19.5 gallons of gasoline. Gasoline ALREADY uses coal fired electricity just to become gasonline.

In fact, this works out to 7.18 kWh per gallon of gasoline. I can drive 28 miles in my electric Porsche Speedster on this energy, and you can KEEP the gallon of gasoline. In fact, you can leave the barrel of oil in the ground.

Debating the CO2 emissions of the electricity production is falling right into the line they want the debate to take, and it is logically bankrupt. CO2 from Coal compared to gasoline directly works out to LESS THAN HALF of that produced by burning gasoline. But worse, the CO2 from refining the gasoline is much higher than the CO2 produced burning the gallon of gasoline.

Electric cars are obviously cleaner, and you can trace both energy and emissions all the way back to the pre-Cambrian sea if you like, the chain only grows MORE in favor of electric and more gruesome from gasoline.
