I've recently joined a utilities tariff that gives me free electricity between 9am & 5pm on Saturdays. While I'm making sure to do all my laundry and DIY on Saturdays, I was also looking at things like UPS batteries to enable me to use some of that power on other days or at other times. These seem to be prohibitively expensive though, This ups would allow me to run my computer for about 10 minutes at most, and the electricity to do that would only cost 1/600th the cost of the battery!
So far I try to make the most of the offer by moving to Saturday:
- All washing & tumble drying
- All power-tool based DIY
- Weekly meal prep using electric oven (ie curry or casserole for the week)
All of this means I'm using about 10% less electricity on other days of the week, but I'd like to push that even further if possible.
