ECN Forum Forums General Topics of the Trade General Discussion Area Yearly household usage in kWh

We use 22,000kWh per year- Family of 4 with two small children, and electric everything (heat, AC, hot water).

That's an average of 2.5kW/10A, 24/7, which is far less than I'd have imagined.

SteveFehr, I suspect you dropped a decimal point somewhere in your 4:39 post. The power output from a solar array should be on the order of magnitude of 100 watts per square meter--you're an order of magnitude less than that.

No mistake, the numbers I calculate are the average powers you get for an "affordable" a-Si panel once you calculate in all the losses and inefficiencies.

"Peak" output when stated independant of location is meaningless- a supposed 100W panel that makes 100W at noon on a cloudless day at the equator is never going to get even close to that in Maine. And when you time average it across a 24 hour period, it drops even more.

This is about an average bill here ($170)in decent weather... It also says I use 38.9KwH /day

We have an 8 room house (no electric heat) central AC in New England.
We average 10,000KWH per year or about 833KWH per month. It has been fairly consistant over the past 10 years. The price of course has gone from .11 p/kwh in 1993 to .20 in 2006. Nearly double.

We use 1400 KWH/month average.

That includes our house, my shop, and my wife's business - several computers run 24/7.

Heat pump, lectric hot water, electric cooking.

All these electricity bills from round the world seem to have a common factor, that of deliberately obscuring the real price of the product from the consumer. I don't buy a liter of milk at the supermarket and get told the milk is 70 centimes plus 3c for the bottling plant costs, 2c extra because the cost of silage just went up, plus 12c taxes, minus a 2c bonus for buying it on Wednesday afternoon, plus 2c for measuring out a liter, so why the heck do I have to put up with it from the poco?

Utility regulation... Your tax dollars at work

I gotta love the "Customer Charge" of $21.00 on my bill. Funny how there's no explanation of what that charge is for, although I assume it's the minumum the bill would be outside of any power usage.

Deregulation required the utilities to unbundle their rates. So now you get to see generation charges, transmission charges, fuel charges, etc.
If your lovely State representatives ever unbundle grocerys, you will see feed charges, milking charges, transportation charges, shelf stocking charges,etc.
