I think electric cars are going to take over in the near future.
The problem is the manufacturing of the car and the fact all machinery used to build and make the cars are run by coal and greenhouse gasses/oil etc.
This is kind of defeating the object isn't it?
Its not really fighting the global warning phenomenon.
Not that I'm a believer in that anyway.
Good post anyway :)
As soon as you have civilization you have greenhouse gasses. There is no way around it. Even cows are contributing to global warming.
Transportation causes about 1/3 of a global pollution. Therefore electric cars could be a better way. Electric motor can have efficiency up to 98% while combustion engines are 30 to 45% efficient.
