What are facts on the light bulb?

Answer 1

1 The light bulb was invented in 1879 by Thomas Alva Edison.

2 When you turn on a light bulb only 10 per cent of the electricity used is turned into light, the other 90 per cent is wasted as heat.

3 In the UK we waste £140 million a year by leaving our lights switched on unnecessarily - this causes 900,000 tonnes of CO2 emissions, enough to fill 180,000 hot air balloons!

4 Low energy light bulbs last on average up to 12 times longer than traditional fluorescent bulbs.

5 Each low energy light bulb you install in your home could save you as much as £9 per year in energy costs, or £100 over the bulb's lifetime

6If every UK household installed just three compact fluorescent light bulbs in place of traditional bulbs, enough energy would be saved in a year to supply all street lighting in the UK

7 UK households use £1.9 billion worth of electricity every year on lighting

8 Energy efficient bulbs last up to 12 times longer than their inefficient counterparts

9 A heavy coat of dust can block up to half of the light

10 If everyone installed one energy-saving light bulb the carbon dioxide emissions saved would fill the Royal Albert Hall nearly 2000 times.

Answer 2

The light bulb was invented by Thomas Edison in 1879. It revolutionized the way we light our homes and businesses, leading to significant advancements in technology and improving our quality of life. Light bulbs operate by passing an electric current through a filament, heating it until it produces light.
