Saving Electricity

House 2 - 2009 Survey Of Electricity Use

Below is the initial survey carried out in December 2009. Items identified in the survey with potential for future savings or further investigation are coloured orange, items changed are coloured green. Some of the likely returns are not cost effective because some light fittings have been changed to suit our tastes as well as fitting low energy bulbs.
The predicted quarterly savings from the completed changes is £3.93.
