What electrical devices waste electrical energy?

When you waste electrical energy you are running up your costs while getting no benefit. Also the local power plant has to work harder so it uses more fuel and produces more CO2 than necessary.

Not many people realise that the fuel used and CO2 created in a power plant each hour is closely linked to the amount of energy consumers take. When you switch something off, the power plant can relax a little and it then uses a slightly lower fuel flow.
