#1 way to save electricity

One way to save electricity is to unplug what your not using. People say that turning off what your not using is enough but the device is still charging. If every computer and monitor was turned off at night it would save 7,000,000,(million) tons of co2 from going in the air. There are 2 ways to do it. One way is to unplug it manually every night. Another way to do it is to get a power strip and plug everything in there. Then you would only have to switch the power switch off.
