Electricity bills

[watervole]

I just got my electricity bill. It's a lot less than the comparable bill for the same quarter last year. £30 less.

There's inevitably going to be some random variation depending on when they actually read the meter and when they've estimated and got it wrong, but I'm still pretty confident that the saving is real.

The usage was 686 kWh as opposed to 1201 kWh

That's a reduction of over 40%!

I'll wait and see what the bill is next quarter before I cheer too loudly, but it looks as though the measures I've taken to cut the electricity usage (without reducing our standard of living) may be having a real effect. That's a lot of carbon dioxide saved, as well as hard cash.

The gas bill is also well down, but the weather has been very mild, so I don't yet know how much of that saving is due to the double glazing and other insulation work.

Cheers - I will look through your tags since you took the time to enter them.

I've seen the electricity usage meters in B & Q, but these were more expensive than the tenner watervole mentioned. However the folded/compact fluorescent lights are definitely a good energy saver as they are direct replacement for ordinary bulbs. for example I replaced the three sixty watt bulbs in the sitting room with eleven watt fluorescents and, assuming four hours daily, saves over two hundred kilowatt hours or about £20 in a year.

I use them wherever possible already. I only have a few incandescent bulbs left - where the energy saving ones wouldnt fit.

I found that changing the light fitting so that you could use an energy saving bulb was cost effective. We got a flush fitting that took a circular energy saving bulb in the lounge. Gives more head room and will pay for itself in two years even given the cost of the new fitting. Looks very nice too.

I basically have two lightshades which are too small - one in the front room which I will change soon, and one in the bathroom which I will leave as it is.

Half the problem is the word "shade". Think of it as blocking a significant proportion of that light you are paying for. Glass ones have a lot going for them, but if you can find a fitting that uses a circular flourescent tube (which may also come with daylight spectrum light if you get the right one) then you have no light blocked at all. B+Q do some nice ones.

There was once a formula for deciding whether a given light fitting/source was appropriate for a given situation (this was before compact fluorescent bulbs were easily available). It was really for industrial or commercial settings and factored in the cost of fitting any replacement support equipment. It went something like less than 1 1/2 hours per day - leave it be, 1 1/2 to 2 1/2 hours switch to Halogen bulbs 3 hours and up switch to standard fluorescent fittings.

Now the cost of compact fluorescents alters the equation.

After last night's comment I stopped and worked it out, given that we've replaced many of the incandescent bulbs (and all those which have a high usage) the saving is somewhere between five hundred and fifty and seven hundred and fifty kilowatt hours per year. We haven't noticed it as electricity prices have been climbing in rough step with our reduction in use!
