Current Status Of Wind Power Generation For Street Light In China

- Feb 11, 2019-

In recent years, energy-saving street lamps have gradually entered the streets and lanes of cities. Their simple installation, beautiful appearance, wind power generation and no need to consume electric energy have attracted the attention of the citizens and have been praised as the city's "street light".

 

Compared with ordinary street lamps, wind power street lights have many unmatched advantages: they are not affected by the power supply, they do not need to excavate the trenches to lay wires, and a small pit can be installed to build the cement foundation; each lamp is an independent power generation lighting. The system does not need to be controlled by the person; it does not consume conventional energy; as long as the wind is sufficient, it can be installed locally. Therefore, it has been widely concerned, and it is called a green product because of its zero emissions and no pollution.

 

Wind power is a new type of green energy. According to statistics, wind power can reduce 600 tons of carbon dioxide per kilowatt-hour of electricity produced. The state encourages the development of wind power to achieve the goal of 100 million kilowatts of wind power in 2020, and the prospects for wind power development are broad.

According toChina's wind power 12th Five-Year Plan, the capacity of wind power equipment reached 100 million kilowatts in 2015, and the annual power generation is 190 billion kilowatt hours, accounting for more than 3% ofChina's total power generation. By 2020, wind power capacity will exceed 200 million kilowatts, and annual power generation will reach 3,900 kilowatt hours, accounting for more than 5% ofChina's total power generation.

 

According to the “China Wind and Light Complementary Street Light Industry Market Research and Investment Forecast Analysis Report” released by the Prospective Industry Research Institute, the total number of urban and rural street lights in China is about 200 million, and it is growing at a rate of 20% (40 million/year) per year. Among them, the street lighting of urban streets is about 15 million baht: the annual demand for new urban street lamps reaches 3 million baht. In 2012,China's new highways were 58,672 kilometers. In 2013, 80,000 kilometers of new roads were built, and 200,000 kilometers of rural roads were rebuilt. If the 200 million watts of 400 watts or 250 watts of high pressure sodium lamps are all converted into 150 watt or 100 watt wind and solar hybrid LED street lights, and each street lamp works 12 hours a day, it will save 150 billion kWh in one year.
