Problems solved by technology

[0002] Various problems such as energy crisis and environmental pollution have prompted us to rely on the technological revolution to ease the conflict with nature. Since the 21st century, we have begun to advocate sustainable development strategies and guide the development and utilization of renewable energy. Solar energy, wind energy The emergence of various new energy sources such as ocean energy and ocean energy has brought a new dawn. Nowadays, some street lighting systems can already use solar energy technology for lighting, and in grassland areas, there have also been technologies that use wind energy to generate power for street lights, but there is no such technology. A system that can perfectly combine the two, not only can use solar power generation technology, but also can not waste wind energy, so that the two can effectively unify the power supply for street lights, and store the excess power supply battery, which greatly improves the new energy. In addition, in the process of power supply, due to the characteristics of battery charge and discharge, the high efficiency of battery charge and discharge is also a factor affecting power supply. Again, in solar power generation and wind power generation technology, relying solely on external energy sources does not have a reasonable protection The battery technology also causes a waste of battery resources, so it is of great practical value to develop a high-efficiency automatic solar and wind power supply system
