In fact in the past 30 years business and industry in the US have made a lot of advances when it comes to conservation.

But in a world run by consumerism, we have to use a lot of energy to make things to be bought and discarded.

At present, however, the biggest portion of the energy we generate is spent on obtaining energy.

The best fuel of all is electricity.

That's why a policy to practice conservation at every level leads inevitably to nuclear energy obtained from energy-dense uranium to make electricity. It can power transportation as well as all the other sectors of society.

But we need solutions to global warming yesterday. So to make the transition to all-electric transportation will of course require nonpolluting synthetic fuels.
