I have contributed to quiet a lot of threads of power savings in the home.
After a year trying to limit my electricity usage to as low as I can go without unduely effecting my quality of life.... I finally got a concrete non-estimated reading by my retailer.
I phoned them up this morning after they had a few days to process it.
I was £44 in credit. Hmmm... "That's not what I was expecting."
"That's after your credit settled your quarterly bill."
So my quarterly bills where £320 or there abouts. So I saved about £364 or about 30% last year!
This year I added an off grid solar power source for the office, with some incremental upgrades it should, I hope, take another 25-30% off that bill next year.
I'm basically down to the high power stuff. Laundry, oven, coffee machine. Those are a little harder to replace with off-grid gas or small scale solar. However, I have finance clearing on the natural gas heating upgrade and hope to take out more finance on roof top grid-tie solar. If I schedule high power items for sunny days I could cut my quarterly bills to <£100!
