If you would like to monitor your use of electricity there's an opportunity to borrow a home energy monitor from Wealden District Council.
The council has 120 of the machines available and will loan them out, from Monday, March 29, on a first come first served basis from its offices in Crowborough and Hailsham.
The offer is being made in support of Earth Hour being held on Saturday when residents are encouraged to switch off lights and any unnecessary domestic appliances at 8.30pm for one hour.
Trials of the home energy monitors show that households have been able to reduce their electricity usage by up to ten per cent.
The Current Cost monitors, which will be loaned for three weeks at a time, track energy usage of electrical items. They also detail the running costs and how much is being consumed at different times of the day.
As they are returned to the council other households will be able to take part in the energy saving challenge. Proof of name and address will be required.
The council is committed to a 12.5 per cent reduction in its own carbon emissions by 2012, compared to 1990 levels.
