Lighting: the facts

The fast and efficient way to make a difference

The facts

• A 100w light bulb left on for just 1 hour creates enough CO2 to fill a party balloon.
• UK households spend around £2.4 billion every year on electricity to power their lighting.

The solution

• Energy saving light bulbs use different technology
  that enable them to produce a highly efficient and
  compact light using a fraction of the energy.
• If you buy an energy efficient light bulb rather than
  the other alternatives, you can cut energy wastage
  by over three quarters. That’s a saving of £3 a year
  for an average bulb, or up to £6 for brighter bulbs,
  or those used for more hours a day.
• Replacing all the remaining traditional inefficient
  light bulbs in your house could save you around
  £50 and 170kg CO2 a year, or £675 and 3 tonnes
  of CO2 over the lifetime of the bulbs.
• Energy efficient bulbs last around 10 times
  longer than their inefficient counterparts. 

The stats

• If everyone in the UK switched all their remaining
  traditional inefficient light bulbs to energy saving
  light bulbs, the electricity saved in just one year
  would run the UK’s street lighting for over 5 years
  or provide electricity for every house in London
  for 11 months.
• If every UK household installed just one extra energy
  saving light bulb in their house, the CO2 saved would
  be equivalent to taking 93,000 cars off the UK’s roads.
