As part of the 10:10 challenge, E.ON is offering a range of free tools, including an online energy tracker, and handheld device to measure energy use in the home, to help customers understand their energy use and make the savings.
Marketing communications will be focussed on online activity to encourage customers to sign up to the challenge.
The energy supplier is giving away 30,000 PowerDown units to customers that pledge to take up the challenge and make the energy cuts.
The PowerDown units link up household televisions and computers and which automatically shuts down all equipment when the main unit is switched off.
Customers that use the online energy tracker will also receive further advice and energy saving offers throughout the year.
Jim Macdonald, Commercial Director of E.ON’s retail business, says: “Targeting our customers to cut their energy use by 10% by the end of 2010 may seem like a bold move, but we’re committed to helping our customers rise to the challenge.”
