Why Sustainable Power is Unsustainable

As has been preciously pointed out, the "100 sq miles to provide ALL US energy needs" is in error. It's an area 100 miles ON A SIDE, that's 10,000 sq miles, NOT 100. By my calculation, at current practical conversion efficiencies of 25%(then divide by 2 because we only have 1/2 day of sunlight), even 10,000 sq miles won't do the trick. At best it could only provide 1.3 Terra Watts of generating capacity and that's not even deducting for cloudy/stormy days,,,note the following link, which states we are currently generating 3.9 Terra Watts of electricity, not the 1.3 that might be generated by 10,000 sq miles of solar. 3.9 T-Watts is a far cry from 1.3.

"Total electricity consumption, including both purchases
from electric power producers and on-site
generation, grows from 3,903 billion kilowatthours
in 2007 to 4,902 billion kilowatthours in
2030, increasing at an average annual rate of 1.0"

The above is on page 11 of the PDF,,,
