The amount of energy released by the sun in just one second is enough to power the people of Hong Kong for 45 years! Solar energy is incredibly powerful, with approximately 3.83x10²⁶ joules being released every second. In Hong Kong, the annual electricity consumption is about 2.72x10¹⁷ joules. In other words, the energy generated by the sun in just one second can sustain the electricity usage of Hong Kong for 45 years! Howls ever, due to the sun's distance from Earth, the amount of energy received by our planet is relatively small. We should make good use of it!
