Solar power is produced from sunlight striking Earth. It strikes the Earth, which is approximately 186,000,000 square miles, at a rate of 1.447 kW per square meter. Solar energy collectors can convert 10% of it into useful power. If humans use a total of 17 TW (terawatts), what percentage of Earth should be covered with solar energy collectors to provide sufficient power?
