"The total power needs of the humans on Earth is approximately 16 terawatts. In the year 2020 it is expected to grow to 20 terawatts. (Ed. A terawatt is a trillion watts.)
The sunshine on the solid part of the Earth is 120,000 terawatts. From this perspective, energy from the sun is virtually unlimited."
