The sun is enormous source of heat and energy. It has a surface temperature of 10 thousand degrees Fahrenheit and generates 380,000,000,000 billion megawatts of power. Hoover Dam in Nevada only generates 2,080 megawatts. In 1 second the sun turns out more energy than being used in all of the human civilization. All that power in a blink of an eye! Incredibly it’s been burning this way for billions of years!
