There''s an ad on TV telling us that a square, 96 miles to the side, full of solar panels, would re-power America.
OK, what's the cost of a 96 mile square full of solar panels?
96 miles is 506,880 feet.
The average solar panel takes up an area of roughly 2 feet by 4 feet.
It takes 126,720 4 foot panels to cover the 96 miles. That's one row of panels, 2 feet thick, in a say, east/west orientation.
The other dimension of the panels, 2 feet, means that 126,720 panels will cover only half the distance in the north/south orientation.
So there will be 253,440 panels for each four foot distance covered in the east/west direction. Thus, we need 126,720 columns comprising of 253,440 rows each, of panels to fill up the 96 mile square.
How many 2' x 4' panels is that total? Multiply 253,440 by 126,720.
My calculator says that amounts to roughly 32,131,000,000 panels. The average cost of a 2' x 4' solar panel is about $300.00. Now multiply 32,131,000,000 by 300 dollars. You do it... my calculator craps out with numbers like that. Roughly, that's 32,131 times ten to the sixth, times 3 times ten to the third, or 96,393 times ten to the ninth.
That's 96,393 followed by nine zeroes.
$96,393,000,000,000.
And that's just for the panels. No power grid, no mounting units, no distribution centers, no wiring, no construction costs... just the panels.
Far larger than the entire world GNP. Even bigger than Obama's budget, that uninformed simpleton pushing for solar and dissing coal.
Go solar.
Even if the panels were only ten bucks each, who can we get to build 32 billion, one hundred and thirty million units? And how long would that take? So if my math is off and it only takes 3.2 billion panels, the same delivery dilemma rears its ugly head. The entire world has not produced 3.2 billion TV's since the invention of television.
And don't forget, half the time it's nighttime in America, so we would need batteries to store the energy. I'm not even going to try to figure out how many billions of batteries that would take, or how much they would cost.
We still need our coal plants, and a lot more nuclear. Solar will NEVER cut the mustard, not with today's technology.
Those solar people are just ignorant of reality. Ignore them.
Wind? The numbers come down roughly in the same ballpark.
