All the world’s power from the Sahara

Using our best solar concentrators an area in the Sahara about 150 x 150 miles would provide all the electricity for the whole world.

Repeat:

“If you assume these 64,516 square kilometers (64 billion square meters) were to have an output of 100 watts per meter, at 7.0 hours per day at 100 watts-hours per hour per square meter, this array would throw off 45 billion kilowatt-hours per day, or 395 trillion kilowatt-hours per year.

“This imputes a constant 24-7 supply of 1,882 gigawatts, or 1.8 terawatts of electric power. The US draws about 450 gigawatts (or .45 terawatts) of electric power, or by these reckonings 24% of total global electrical output.”

Ecoworld imputes, “…sounds plausible.”
