Electricity usage review

Here's a funky table that my Carbon Watcher person made for me, along with some information and a graph of my electricity usage since December 2008.

I have to admit, my mind has been on other things lately, but with the 1st of a new month upon us, I'm going to take another reading today and see where we can cut back further:

Date	Elec read	kWh	kWh/day	tCO2
09/12/2008	96207	640	20	0.344
01/01/2009	96661	806	26	0.433
01/02/2009	97467	472	17	0.253
01/03/2009	97939	525	17	0.282
01/04/2009	98464	463	15	0.249
01/05/2009	98927	503	16	0.270
01/06/2009	99430	646	18	0.347
06/07/2009	77
Total		4055		2.177

The kWh for December are pro rata as there was nearly a third of a month “missing” but the kWh per day is real. I’ve put this in to help you see whether your consumption is really increasing, as feared. 1 kWh difference per day is the equivalent of having a 1 bar electric fire running for an hour, or a 60W light bulb on for 16 hours every day - so quite a lot of energy really! If you’re already pretty on top of your electricity use (and I think you are) I think you’re right to query the immersion heater.

Don’t be disheartened about the increase in electricity usage – it’s only a 5% variance and as your footprint was tiny to start with it was always going to be harder to see any savings made.

Since the beginning of Carbon Watchers in December 2009 you’ve been sending us
monthly readings from your electricity meter. From this we have calculated
your carbon emissions over the last seven months as follows:
•
You’ve used 4,055 kWh of electricity, which equates to 2.2 tonnes of carbon
emissions. That’s enough to fill 12 double-decker buses! To offset this amount of carbon you’d
need to plant 9 trees and maintain this number to keep the carbon locked away.
The graph below shows the pattern of your carbon emissions from electricity:
