Summary
Of Electricity Cost Savings
|
 |
This graph shows
how daily electricity cost has varied over the last few years.
The wide short term variations are partly caused by the irregular
intervals at which I check the meter readings and partly
by usage changes caused by the number of people in the house.
Clearly day time use is still the biggest single element
of cost. Although the peak over Christmas is around the same
as last year the average at what is the highest usage point
in the year looks lower. |

This graph shows the percentage
electricity cost saving by comparing costs with October
2003. The dip in December 2004 was caused by a mad moment
when I covered the house with fairy lights for Christmas.
Part of the saving can be explained by transferring a greater
load to run on cheap rate electricity. Despite the massive
cost rises over the last few years we are still paying less
for electricity compared to 2003. As expected costs peaked
again last Christmas. If today's costs are applied to the
2003 electricity usage the cost saving is a massive 40%. |
