Growth in electricity usage and growth in America's economy used to be tightly linked. A 1% increase in GDP led to a near 1% increase in electricity usage.
But in another sign of the great American energy diet at work, the link between economic growth and growing electricity demand is weakening and may soon snap, according to Duke Energy's CEO.
Duke Energy's CEO, Jim Rogers, says that a 1% increase in GDP now leads to an 0.4% increase in electricity demand and is still weakening.
Soon the American economy may well grow without using much more electricity. That would be an amazing change of a longstanding, key fact in the energy world.
