Wind is moving air that is caused by the difference in air pressure due to temperature differences. Learn facts about the wind and explore what causes wind and how it can be harnessed. What is Wind? In a hurricane, it can reach speeds of more than 130 miles per hour. In a tornado, ...
The real facts about wind energyMiles George
The sun was born about 4.6 billion years ago. Many scientists think the sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust known as the solar nebula. As the nebula collapsed because of its gravity, it spun faster and flattened into a disk. Most o...

Below are 35 Facts About Wind Energy Fact 1: Wind power consists of turning energy from the wind to other energy forms. There are different ways to harness it. For example windmills produce mechanical energy, enable sails to move boats and generate electricity. Fact 2: Windmills have been in...
The Sun will one day be about the size of Earth. After its red giant phase, the Sun will collapse. It will keep its enormous mass with the approximate volume of our planet. When this happens, it will have become a white dwarf.
