Energy-saving tips

Just switch it off
Stereo systems, VCRs, TVs and other electronic entertainment equipment are often left in standby mode, consuming unnecessary electricity. The devices still use electricity, even though they are switched off. For example, a television left in standby mode can increase your annual electricity bill by 20 euros. Therefore, always completely disconnect devices from the mains when not in use. Why not simply use a socket strip with a switch.
