Putting your television into standby still costs you money because any device which lives on standby uses electricity, even when it's asleep.

Most of us have at least one DVD or Blu-ray machine on standby, and perhaps a gaming console and music system as well as your television. That quickly amounts to a lot of wasted wattage.

An LED LCD television uses around 0.02 cents and 0.01 cent per hour when on standby. Multiply this by how many hours it remains idle through the day, and then through an entire year, and it may well shock you.

Now consider all the rest of your appliances, and it’s enough to switch you off! The New York Times has an enlightening article which addresses this standby problem.

I've gotten in the habit of turning off the switches every night before I go to bed. I have a 55-inch screen with a home cinema connected to it. As a result, I am all too well aware of the amount of energy they consume.

I use an ​Alexa ​​​Alexa Dot with Alexa controlled sockets so that every night, I tell Alexa to shut everything down. My heavy energy pieces of equipment, namely my television and home cinema system, are then switched off at the plug entirely, which gives me peace of mind.

While they are off at the sockets, they are not using energy.
