America’s Energy Efficiency
Over at the Enterprise Blog, Steve Hayward posted this really compelling-yet-humble video showing, well, I’ll let him explain it:
The video below displays the percentage change in GDP and total energy use in the United States from 1970 through 2008. The percentage scale on the vertical axis is a little difficult to make out, but the raw numbers look like this: total energy consumption is up 53 percent during the period, while real GDP increased 209 percent. The result is that U.S. energy efficiency increased 43 percent.
