Right!  The U.S. is the #1 energy consumer in the world.  We're #1!  
Considering petroleum, natural gas, coal, hydroelectric power and nuclear
power,
we used over 5 times the energy that our population represents in the
total world population, by 2003 consumption figures
. The vast bulk of the world
population uses far less than their population percentage.  For example, China,
with a burgeoning economy and a population of 1.3 billion people, represents
20% of the world population, and consumed 11% of the world energy supply in
2003.  We used 9.4 times the energy per person here in the U.S., compared
with China.  For poorer countries than China, the imbalance is much greater.

Developing countries like China and India are changing the energy landscape.  
As they undergo rapid economic growth, they bid up the price of energy.  No
matter where the energy is produced (whether the Middle East, Southeast Asia,
Canada, the U.S.A.) the energy market is a world market, and energy
resources will flow to where the money is.  We can't count on being able to
sustain our disproportionate consumption of energy resources.  Large
multinational corporations like Exxon, Shell, BP, etc. will sell petroleum to the
highest bidders -- there's not even a guarantee of American oil going to
American customers!  
For this reason, it would be wise for everyone to prepare
for the future of high-cost energy
.  

Take a look at the comparison between some selected countries, and the
percentages of the world's energy consumed in 2003:
