Well, the vehicle sector has always been the hardest sector
for global warming, in part because gasoline is such a simple
and attractive fuel. You know, you can make a power plant
cleaner; it costs money, but it's really not that hard. But to
make your car cleaner, you have to somehow use a lot less oil
and ultimately find some sort of alternative that has the same
convenience as oil, but has a lot lower emissions. And that
has proved difficult.
So— And this is true of the entire transportation
sector, not just cars, but also airplanes. How do you replace
jet fuel with something that's greener, when there's such a
premium on weight and volume? And there's few things that have
better energy characteristics than, you know, petroleum.
So I think there's no question that the transportation sector
is the toughest sector to deal with when it comes to global
warming and we're going to need some advances pretty darn soon
if we're going to tackle it successfully.
