LED bulbs are now available for virtually all lamps, including those with pleasant warm light colours. You can certainly ensure that some lamps are LED. Simply check the bulbs to see if they are labelled LED. This also applies to schools.

Standby means that your computer, television or mobile phone is not completely switched off, but is merely “asleep” or still has a light on, and the devices can be easily switched on again with the remote control.
Standby power consumption is often criticised and extrapolated. If a television consumes 5 watts in standby mode, for example, that amounts to 120 watt hours (Wh) per day, or approximately one-eighth of a kilowatt hour, which costs about 35 pence. Hardly anyone is going to get up from the sofa for 5 pence a day to press the switch on the television, or switch off the WiFi router at night, or shut down the computer. Or are they? And how many watt hours could be saved every day in all households? Would this consideration influence your actions?

Do you leave the lights on when you are no longer in the room?
Modern lamps consume little electricity, but it is still worth not leaving them on unnecessarily, for example when we are not in the room for a long time.
