Curious to why people associate Electric Vehicles to dirty power. We have plenty of clean power, Solar, Wind and soon Wave will be perfected. Look at how far Solar has come since first introduced and what it will become in another 10 years and so on. The only problem with Electric Vehicles is their price. Having a Solar System I haven't paid a power bill in over 10 yrs and put extra back into the grid, so I can't wait till the price of Electric Vehicles become realistically priced for everyone then no more fuel bills either.
