Some important facts...
Traditional incandescent light bulbs use about 90% of their energy making a metal element white hot.

By comparison, compact fluorescent light bulbs waste very little energy in the form of heat, as they work in the same way as fluorescent tubes (with electricity passing through a gas in the bulb and making a coating on the inside of the bulb glow brightly).

Although incandescent light bulbs are cheap to make, and to buy, they cost more to use because they waste energy and need to be replaced more frequently.

Lighting accounts for 10-15% of an average home's electricity bill, and fitting a single energy-efficient bulb (costing £2-5) can reduce your lighting costs by up to £7 a year.

In a recent report, the UK'S National Audit Office says that greater energy efficiency is the cheapest way to achieve the UK government's goal of a 20% cut in carbon dioxide emissions, from 1990 levels, by 2010... and to move towards the government's declared target of a 60% cut in CO2 emissions by 2050.

The phasing out, and replacement, of incandescent lightbulbs is necessary because energy-efficient light bulbs are not being used, even though they have been available for over 20 years.

If energy-efficient light bulbs - and similar technologies - are to become widely used, and cheap to buy, more drastic action is necessary.
