People energy saving tips

BBC asked people for their energy saving tips. Here is a selection:

I've told my two daughters, aged 10 and five, that I will give them 2p every time they switch off a light in a room that nobody seems to be using. Apart from the odd occasion when I get plunged into the dark while on the lavatory it seems to be working quite well!
Graham Senior, Byfleet

Don't overfill your kettle when doing a cuppa. Most kettles have a minimum level to fill to for safety reasons but it is often enough for making two cups.
Robin C, Leeds

Delay the need for turning on the heating by wearing more clothing - in layers not necessarily thicker clothing.
Sir Patrick Cable-Alexander, Worthing

It took years, but convincing my wife that it does not take 1.5 litres of water in the kettle to make one cup of tea has saved us a lot.
Dave Stewart, Osnabruck, Germany

I have just moved into a new flat where the electricity meter is really accessible. I can't help but look at it every now and then to see how fast it is spinning - the dishwasher uses loads of electricity which was surprising and the lights in our dining room make it spin faster than the heater does!
Jake Phillips, Edinburgh

I'm annoyed that some manufacturers do not allow you to turn off their devices. For example, my TV has no off switch. It has to be in standby. The wall socket is behind a wall unit so I cannot get to it.
Kevin Rogers, London

Turn off mobile phones overnight so you have to charge them less often.
Rachel Bower, Edinburgh

Adding loft insulation, and taking the heating down by three degrees has saved 20% on heating bills for us.
Rob F, London

What difference does me turning a light off make when a stroll around any large city at night reveals acres of empty buildings lit up against the night sky? It is industry that should lead the way, not individuals.
Lisa Jenkins, Manningtree

If you use a water immersion heater to heat your water, ensure that you keep it off at every available opportunity. Water immersion heaters are massive electricity guzzlers
Mehtab Ghazi Rahman, London

This is utter rubbish. Why do they try to tell the man in the street to save energy retail stores have every TV in the store on.
Agnes Clark, Kilwinning Ayrshire

I often fill the kettle up in the morning, then transfer all the hot water over to a vacuum flask. I have found that it can save you putting the kettle on up three to four times.
Damien Read, Neath, West Glamorgan
