Will Hybrids Save the World?
However, others cite an unexpected interest in hybrid sales, noting that, if current trends continue, 80% of new cars sold by 2015 could be hybrids. But that's an optimistic estimate, and even if it came to pass, it might not put a dent in oil consumption.
A Booz Allen Hamilton survey shows that, even with aggressive hybrid adoption, oil consumption wouldn't likely fall until nearly 2020. Medium and low hybrid adoption would only slow the increase in the growth of oil consumption.
