For computers, Tv's, DVD players etc just use a regular surge protector and turn it off when the items are not in use. Unplug small appliances in your kitchen when not in use. A lot of things use energy when they are technically turned off. I bought a lot of surge protectors at Target when they went to 75 and 90% off at Christmas. Also make sure to unplug things like your cellphone chargers or any battery chargers.
