2. How Is Energy Used?

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.
