Question by Hiya: How much power do we get from the sun every day?
I need to know how much per square inch at any given time and also the amount the sun gives the earth (in total, the sun is always shining some where) each day.
Best answer:
Answer by Donut TimMost of the Sun’s light is radiated in a direction that does not send it to Earth.
Only 0.000000724654% of it reaches the Earth.
That’s 7.24654 billionths of the Sun’s total light.
The Sunlight that reaches Earth is equal to approximately 1,370 watts per square meter (0.884 watts per square inch) when the sun is at zenith. Because of the atmosphere, the amount of energy that reaches the ground is about 1,000 watts per meter (0.645 watts per square inch) when the sun is directly above and no clouds obscure. (One watt is equal to 1 joule (J) of energy per second.)
The total energy from the Sun that hits Earth is 2,787,020,730,988,480,000 watts.

How much power do we get from the sun every day?
Is it merely a coincidence that the moon is just the right size to cover up the sun during an eclipse?

If it were smaller or larger, we would not be able to observe the sun during an eclipse.

Question by Michael: Is something going to happen between May 20th, 2012 and June 6th or just after?
I know the solar eclipse is going to happen on may 20 , 2012 but I just saw video saying that theirs going to be a big earthquake and that Nostradamus and Mayans predicted something was going to happen. Is it true what is really going to happen in 2 days I know the solar eclipse but anything else? Should I be worry about? Is the world going to end on December 21, 2012 ? I'm really scare right now

Answer by Vic RattleheadYes, the people that lived 1400 years ago predicted the exact date of the exact natural disaster of something that will happen in a place they didn't even know about at the time using the stars.

The Mayan calendar ends December 21, 2012. It's the end of something called the Long Cycle. As soon as it ends, a new one begins. They just didn't record it. It's like the end of the year. The world doesn't end when there are no more days in the year, a new year just starts instead.
