When were wind and solar complementary street lights invented and applied?

Wind-solar hybrid street light is a street light system that uses solar and wind energy to generate electricity. Its invention and application can be traced back to the 1970s.

In the past few decades, people's attention to environmental protection and renewable energy has gradually increased. Traditional street lighting systems require the use of electricity, which usually comes from fossil fuels such as coal or petroleum, which produces large amounts of greenhouse gases such as carbon dioxide and causes serious pollution to the environment. Therefore, people began to look for a more environmentally friendly and sustainable street lighting solution.

In the 1970s, solar technology began to be widely used. Solar panels convert sunlight into electricity, providing the power needed to illuminate street lights. However, solar street lights cannot work properly at night or on cloudy days, so additional power supply is required. In order to solve this problem, people began to study how to use wind energy to supplement solar energy.

In the 1980s, wind energy technology was further developed and applied. Wind turbines can convert wind energy into electricity to provide additional power for street lights. Wind energy is a renewable energy source that does not produce pollutants, so wind-solar hybrid street lighting systems combined with solar energy have become an ideal solution.

With the advancement of technology, the efficiency and reliability of wind-solar hybrid street lighting systems continue to improve. Modern wind-solar hybrid street lighting systems usually consist of solar panels, wind turbines, battery energy storage systems and LED lights. During the day, solar panels convert sunlight into electrical energy to power street lights; at night or on cloudy days, wind turbines convert wind energy into electrical energy to provide additional power for street lights. Battery energy storage systems can store excess electrical energy for emergency use. LED lights are energy-efficient and can provide bright lighting effects.

The application scope of wind and solar complementary street lighting systems is also becoming more and more extensive. It can be used in various places such as urban roads, rural roads, parks, squares, etc. Compared with traditional street light systems, wind-solar hybrid street light systems have lower energy consumption, longer service life and less maintenance costs. At the same time, it can also reduce dependence on fossil fuels, reduce greenhouse gas emissions, and be more environmentally friendly.

In short, wind-solar hybrid street light is a street light system that uses solar and wind energy to generate electricity. Its invention and application can be traced back to the 1970s. With the continuous advancement of technology, wind and solar hybrid street lighting systems play an important role in environmental protection and sustainable development.
