Power Demand From US Homes Expected To Fall For a Decade
We hear all the time that household energy consumption is rising, both in the U.S. and around the world. That's been true in the big picture for several decades at least, but reader captainkoloth, with his first accepted submission, points to an Associated Press article with some encouraging news on this front: the rate of growth in U.S. household energy use, and household energy use itself, is expected to decline slightly over the next 10 years. Take it for what you will, but that conclusion is drawn by the Electric Power Research Institute, "a nonprofit group funded by the utility industry."
As the last of the vacuum tubes (incandescent light bulbs and CRTs) get phased out, power consumption goes down. Now if we could just find a way to get rid of (most) fractional horsepower motors.
If you can't afford to pay the light bill, your electricity consumption is going to decrease sharply.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
demographic changes and societal changes are probably at least as responsible, if not more responsible, for the changes. Due to the "great recession" American kids are finally figuring out what their counterparts in other rich countries(Italy and Japan foremost among them) that living with mom and dad after graduation and even employment isn't as bad as either forking out massive amounts of money in rent to someone else every month or buying a house/apartment that is pretty much guaranteed to be worth less than you paid for it the second you sign the lease.
As such, as more people live in the same household per capita energy consumption tends to fall as there are more "economies of scale" in things like refrigeration and heating/cooling.....
Whether or not this will be a long term trend like it is in Italy and Japan still remains a question and is critical to long term residential energy consumption estimates.

You were absolutely right to be concerned about the rate of growth metric. Consider 1 + 2 + 3 + 4 + ...
The 2 represents a doubling of the sum so far (200%). Now the sum is 3, so the 3 represents a 100% increase. Now the sum is 6, so the 4 represents a 67% increase. Now the sum is 10, so the 5 represents a 50% increase. Now the sum is 15, so the 6 represents a 40% increase. And so on.
Now suppose that these numbers represent electricity usage. Although usage is monotonically increasing, the rate of growth is monotonically decreasing. Other commenters have pointed out that "TFA" says actual usage will go down. But you were right to be concerned. If actual usage is expected to go down, why didn't they say that? Why did they say that the rate of growth is expected to go down?? That phrase is a major red flag to identify someone who's trying to lie with statistics.
