The Energy Information Administration (EIA) reports that more
than half of our energy (52%) is used by business and industry.
The rest is used for transportation (27%) and to keep us comfortable
in our homes (21%).
The EIA Energy Flow diagram (available on the EIA
Web site and roughly reproduced in the image at right) provides
us with an easy way to see not only where our energy is used but
also where we get our energy.
Nationally, our energy costs are currently around 570 billion
dollars each year. The EIA graphs are helpful in showing how energy
consumption patterns have changed in the last fifty years.
