Energy saving myths

"Computer screen savers save money"

  • Initially used to prevent phosphor burn-in on CRT monitors, screen-savers are mostly used for entertainment; therefore switch off your screen.

"Electrical appliances do not use energy, even when they are plugged in"

  • A majority still can, particularly TVs on standby and mobile phone chargers.  This is known as 'vampire power' waste.  Households can save up to £80 a year on electricity by avoiding this.

"Using the tumble dryer at night is cheaper to run"

  • Whilst this may be true when using 'Economy 7' meters, the majority of UK households are on tariffs that stick at the same rate, and therefore don't save any more than using a tumble dryer during the day.

"It's cheaper to leave their home heating on all day than turning the heating on or off and up or down when required"

  • The most cost-effective way to do this is to turn the heating on and off or up and down when required, rather than leaving it on all day at a lower temperature. This ensures that heat is not wasted and that your home will be at a comfortable temperature.

"Leaving a computer on uses less energy than switching on and off"

  • Start-up current surges use the same energy as the machine would use in a few seconds of average running time.
