Motorists seek alternative fuels amid soaring prices

With oil prices near $140 a barrel, motorists are starting to look seriously at both alternative fuels and electric vehicles as a way to be able to keep driving their cars.

But experts say it will take five to 10 years for these alternatives to take root, given the capacity challenge for an auto industry that is adding 65 million new cars a year to a fleet of 1 billion.

In the meantime, car and parts makers, oil companies and even electricity generators are left guessing which way motorists will turn and what technology will win.
