I don't believe that 'acceptance' among the consumer is really the issue with electric cars becoming a solid reality in society. Electric cars have come a long way over the past couple of years and can travel longer ranges than they had previously. Tesla Motors is now producing the Model S which has options for several battery level options. The lowest, which is 40 kWh can travel a range of 160 miles on a single charge. The battery is said to last 8 years or 100,000 miles. Not only is this car efficient, but it is also visually appealing as well.
The problem comes into play, in that there are not enough charging stations to make driving exclusively electric a feasible decision at the present time. Another problem that influences the move to electric cars, or other alternative for that matter, is that the automakers do not have any incentive to produce anything other than gasoline driven cars. Gasoline taxes pull in a lot of money for the government, and taking that away would not be a good move in their eyes.
GM had started producing the EV1, which was only available to lease, in 1996 as there was a requirement to have at least one plug in vehicle in the automaker's line-up to be able to sell in California. This was the California Air Resources Board (CARB). When that requirement was lifted, GM stopped producing the vehicle and retracted all leased vehicles. By 2002, all EV1 cars were pulled off lease and dismantled.
Ive written a Hub specifically about alternative energy sources which pertains mostly to cars, but could be applied to many applications. I hope that you find it useful.
