Power Demand From US Homes Expected To Fall For a Decade 261
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."

If you can't afford to pay the light bill, your electricity consumption is going to decrease sharply.

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.

There are minimum expenses, you have to have towers sufficient for at least one transmission line pretty much no matter how little your consumption. But, if you halved the power consumption you should be able to at least cut the transmission capacity by a third, if not a full half. And every line you run has to be maintained and every bit of capacity has to be paid for by somebody.
Ultimately, it tends to be better to have the utilities owned by the local government than a for profit entity because any "profits" can at least be sure of going back into the infrastructure. That's how it's been around here for ages and our price and quality is quite good. Price isn't entirely fair because we do have hydroelectric dams to provide power, but even as we've demolished them the price has still remained lower than most other parts of the country.
The thing which really hurt us was when Enron cheater our utilities out of that money when they went under.

Even today's 'high efficiency' halogen lights only produce about 10 lumens per watt. By 2020, all general purpose lights must produce 45 lumens per watt. This effectivly bans all current forms of incandescent lights.

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.

If electricity last year cost 100 bucks per gigajoule, and electricity this year cost 130 bucks per gigajoule and you reduced your household useage from 1 gigajoule to 0.7 gigajoules, you still saved 39 dollars versus last year compared to having not upgraded.
The move is still very smart financially, your point regarding rate increases has no place in this discussion. The same thing happens with water and other infrastructure, a large portion of the maintenance bill for a utility was covered by usage costs in the past, so when usage drops the utility actually loses enough income that they cannot maintain the system and therefore your bill doesn't drop as much as you thought it should. Oftentimes you can see a transmission charge for electricity, this is the approximate cost of what it costs to get your power to you and is upkeep on the lines, poles, and transformers. Depending on the mix of power, your transmission charges can actually be greater than the cost of electricity (say a town fed entirely by a hydrodam 100km away). The fixed cost of electricity is low in this case, but 100km of lines are expensive to maintain. Some people also call this the hookup fee, with negative connotations, but it is well warranted because to use the system it needs to function.
Imagine if people could choose which parts of the bill to pay, and they decided to not pay for maintenance, obviously at some point the system would break down and there would be insufficient cash to fix it so people can use electricity and the utility can bill again! This represents a death blow to a utility, FULL STOP for operations. (this obviously neglects possible short term financing opportunities)
it also isn't surprising that yearly raises are occurring as the boomer generation has largely deferred the cost of maintaining the nations infrastructure time and time again while only applying quick or short term fixes to the grid.
