- Area of earth's surface perpendicular to sun -
- Average insolation - 1000W [1]
- Radius of Earth - 6371 km - [2]
- Pi Arr Squared is 1.3x10^14 square meters
- Solar income is 1.3x10^17 watts upon the earth surface at any time.
Kardashev Scale
- In 2017, we used 162,000 TWh of energy. [3]
- There are 8,760 hours per year.
- Thus, average power use is 18 TW.
- 1.3E17/18E12 = 7222 - Solar Income is over 7000x greater than current primary energy production
- In other words, we are at 0.00014 on the Kardashev scale. That is about 1/100 of 1 percent, or 0.01%.
