Lightning bolts strike Earth about 8 million times every 24 hours. That's around 100 lighting strikes each second.
In Masdar City, Abu Dhabi, there are no light switches or water taps. Light and water are motion activated, helping to cut their usage in half.
The distance from the Earth to the sun is 92 million miles (146 million km). Even at the incredible speed of light, it takes 8 minutes for the sun's light rays to reach us once they leave the sun.
Most people wrongly believe that Thomas Edison invented the light bulb. He improved the existing light bulb at the time, and he invented the electrical delivery system.
The average resting adult consumes about the same amount of energy as a 100 watt light bulb; that's more than 600 AA batteries per day.
Lightning bolts on Earth may get as hot as 53,540 degrees Fahrenheit; that's more than four times hotter than the surface of the sun.
The strongest of lightning bolts produce electromagnetic waves that can be detected anywhere on Earth. The waves can travel completely around the earth two to three times before dissipating.
Earth's tectonic plates move slowly. Some move as fast as human fingernails grow (1 inch/year), while others may move up to 3 times faster.
