These are a couple of plots showing some
information about human use of energy and economy.
use of energy per person per year is on
the bottom, 0, not using any, over to using
a huge amount, and this amount is about a
hundred times more energy used outside the person than inside.
And what you'll notice is this is economic activity.
How big the economy is, how many dollars per person per year, and
poor people don't use much energy, and rich people use a lot of energy.
Now you might first think that that means that rich people are just wasteful.
But what you see above is how much energy is needed to
generate a dollar of economic activity and there just isn't much relationship there.
So, it's not that rich people are wasting more energy, they get
as much activity out of a barrel of oil as poor people do.
They just generate way more economy, and so
you use more energy when you're rich, basically.
