- Only 10% of energy in a light bulb is used to create light. Ninety percent of a light bulb’s energy creates heat. Compact fluorescent light bulbs (CFLs), on the other hand, use about 80% less electricity than conventional bulbs and last up to 12 times as long.
- If a person yelled for 8 years, 7 months, and 6 days, he or she would produce enough energy to heat one cup of coffee.
- If you had a light bulb on the moon connected to a switch in your bedroom, it would take only 1.26 seconds for that bulb to light up, 238,857 miles away.
- If you travel as fast as electricity, (about 300,000 kilometers = 186,411.358 miles per second the speed of light), you could go around the world 8 times in the time it takes to turn on a light switch.
