After two decades of not changing fuel economy
regulations, our cars have gotten bigger and heavier and overpowered and very
inefficient. And the opportunity is to make those cars efficient over the next
two decades, particularly by introducing hybrid technology. So that's
sort of phase one. Phase two is then to move from hybrids to the advanced
hybrids or plug-in hybrids, and start actually switching out gasoline for
electricity and also for cellulosic ethanol.
So in that two-phase transition, by the middle of this
century the cars might emit 10 percent, 20 percent of the greenhouse gases that
they emit today. It's not going to happen overnight, particularly because
people own their cars for two decades now, so it takes a while to shift out the
old cars and bring in the new cars. But I do think that steady push by the
federal government is the ticket to reversing the emissions trends on
greenhouse gases and finally cutting them down.
