Economics of SWG in high electricity cost area?

[blueman2]

Here is Northern California bay area, PG&E charges 37 cents per KWH for anyone who uses any real amount of electricity (the more you use, the more they charge per KWH). Given this super high cost, does SWG still make sense? Given the initial cost of purchase and installation (assuming about $1000) and the cost of replacing the cell every 5 years (another $400), and the high cost of electricity, I am starting to wonder.

Any idea how much power a 40,000 gallon cell uses in terms of KW?

A SWG uses very little electricity, typically less than 1 kWh per day, or roughly $11/month at your rates. This varies somewhat by brand, but they are all around there, and not in the same league with things like pumps.

Thanks! There appears to be a lot of misinformation floating around on how much electricity SWG use. There are a few sites I have run across that imply they use as much as a single speed pump. Thanks.

Those who have an agenda against SWGs have used operating cost figures that include the cost of running the pump as well as the electricity for the SWG itself.
