Do you use electricity when things are plugged in but not on?
According to the Energy Saving Trust, any switched on charger that is plugged in will still use electricity, regardless of whether the device is attached or not. The amount of electricity produced from this only costs a few pence, but it will shorten the shelf life of the charger.
Does it use more electricity to turn TV on and off?

Does leaving the TV on all night use a lot of electricity?
It turns out that doesn’t cost you too much, thanks to modern TVs: current EnergyStar models use only 30-60Watts for a 40″ TV, so those 4 hours asleep cost you about 2 cents. If you have an old TV, however, it can consume as much as 400W – in that case your nap costs you about 15c.

Is it OK to leave the TV on all day?
The first thing to know is that all TVs dim over time. The phosphors in a plasma, the CCFL lamps in traditional LCDs, and even the LEDs in LED LCDs, all age over time. … So in the long run, the a TV left on all the time will get dimmer, sooner, than if you only watched it 4 to 6 hours a day.
Does turning switches off save electricity?

Do LED lights last longer if you leave them on?
To put it simply, well-manufactured LED lights are extremely long-lasting and can be left on 24 hours, 7 days a week. This is because, unlike conventional types of light, LEDs produce minimal amounts of heat, which means they are unlikely to overheat or set on fire.
