Solar energy is the energy produced by the continuous nuclear fusion process inside the sun. The average solar radiation intensity in Earth's orbit is 1367kw/m2. The circumference of the Earth's equator is 40,000 km, which makes it possible to calculate that the Earth can reach 173,000 TW. The standard peak intensity at sea level is 1 kw/m2, and the annual average radiation intensity at a point on the earth's surface for 24 hours is 0.20 kw/m2, which is equivalent to 102,000 TW of energy.
