Since the 21st century, China’s social economy has been developing rapidly, and the demand for electricity has also been rising. Now that energy is in short supply, the supply of electricity has not been able to keep up, plus a large number of thermal power generation emissions. The induction of gas also causes environmental pollution. We need to use new energy sources to solve these problems. This requires the use of solar street lights. China has abundant solar energy resources. Solar street lamps that use solar energy as energy are applied to outdoor lighting. This is a good solution for the country to implement energy-saving emission reduction. If we continue to use ordinary street lamps, let alone provide electricity. No, it will consume more than 1,000 degrees a year, consume more than 400 kilograms of standard coal, and the harmful gases emitted will further aggravate the deterioration of the environment.
