Criswell estimates that the 10 billion people living on Earth in 2050 will require 20 Terrawatts (TW) of power. The Moon receives 13,000 TW of power from the sun. Criswell suggests that harnessing just 1% of the solar power and directing it toward Earth could replace fossil fuel power plants on Earth.
