Switch off and save cash

By Peter Hanson

Those who had an infra-red survey of their houses carried out in February were also loaned a pack of useful things to help them save energy. One of the most useful of these was a hand-held electricity meter which monitors how much electricity your house is using at any one time. You can walk around the house switching things on and off and see how much electricity each is using.

What's surprising though is how hard it is to get the meter to read zero. Even with no fridges, freezers, lights, heating pumps or anything obvious at all on, our meter wouldn't go below about 45 to 50 watts. Given that every Watt costs about £1.30 for a year, 50 Watts would cost about £65.

After a bit of research we found out what was consuming these extra Watts. Some things you wouldn't want to ever switch off anyway ,- things like the mains powered smoke alarm (5 Watts), door bell transformer (4 Watts), Broadband (5 Watts), cordless phone charger (2Watts), infra-red detectors for security lights (4x5Watts).

There were some surprises though,- for example the electric oven used 10 Watts, the food mixer (plugged in and switched on at the socket) used 4Watts, the washing machine 2 Watts, microwave 3 Watts and even the toaster was using 2 watts! The TV and digibox together used 9Watts.

So it seems as though anything that has electronic controls is likely to be using power all the time but things like a kettle that just have an on/off switch shouldn't. So if you can switch something off at the wall socket without causing difficulties, it's a good habit to get into.

How we can close seven expensive power stations and you can save yourself some money

By Tom Langdon Davies

Every weekday from November to the end of February, starting at around 3:30pm, electricity demand in the UK rises, and by about 5:30pm it is 7GW (seven million kilowatts) higher. That's about 300 watts per household on average. By 8pm, demand has usually fallen back to its pre-peak level.

It takes seven large power stations to supply this peak, over and above those required during the daytime plateau.

The reason for the peak is simple. At this time, offices shops, factories are still working, and people are starting to come home from school and work. So workplaces and homes are using electricity at the same time.

Some large businesses and factories are paid to reduce their electricity demand during these periods. But not enough to prevent the peak and the seven power stations' worth of electricity it requires.

We could close these power stations and associated transmission lines without replacing them, at a saving of between 7 and 10 billion pounds

What can we do about it?

Surprisingly, perhaps, the answer is simple, cheap, and will save you money with little or no loss of convenience.

It's simply this-

  • Switch off your immersion heater for a few hours if you have one. If possible, from 3:30pm to 8pm but particularly around 5:30pm for as long as you can without inconvenience.
  • Don't switch on your washing machine, your dishwasher or tumble drier during these hours.
  • Set your freezer and fridge to go off for some or all of these hours.

If 3 million of us did it, we could close down one power station.

If all 23 million households in the country did this, we could close down seven power stations.

What will it cost me?

If you do it manually, nothing.

But to make your life really easy, you could fit a £20 timer to your immersion heater. A side effect will be that you will use less electricity.  I calculate that I have saved about £50 over a year as a result of fitting one. So the timer could pay for itself in less than six months.
