Electric cars are the way of the future. Granted, the technology is over 150 years old, and there really hasn't EVER been a really good excuse to not have them, but it's likely they will start rolling out in far greater numbers, and the technology will continue to improve. The number of companies selling them is certainly going up, we have the Chevy Volt coming out pretty soon, and a lot of startup companies selling electric cars like Tesla, and BYD Auto, a Chinese firm that has an all electric model that unveiled in December 08. The only really big problem at this point is range. Once the technology improves that gives an all electric model a 500 mile range and a quicker charge and then an affordable price - gas burner will be out the window. We probably will see electric majority in cities within 15 years.
