From July 1st, the "Regulations on Urban Lighting Management" will be implemented. The new regulations stipulate that the state encourages the installation and use of renewable energy utilization systems such as solar energy and wind energy in the construction and renovation of urban lighting facilities.
It is understood that urban street lamps are large consumers of electricity, and many cities have experimented with installing new energy street lamps such as solar energy and wind energy to reduce the consumption of electric energy. Up to now, a total of 52,000 street lamps have been installed in Xiangfan City. Last year, urban street lamps used more than 1516 million kWh of electricity, and the annual electricity consumption was about 14 million yuan.
In order to save electricity consumption for street lamps, in August 2008, Xiangfan installed wind-solar complementary street lamps in Fancheng Yanjiang Avenue, using wind energy and solar dual system power supply; last November, installed solar panels for the ancient city wall of Xiangyang Road to the lady The city's lighting and lawn lighting, the new energy street lamps save 8 million kWh, and the results are in the forefront of the province.
However, the energy-saving effect of new energy street lamps is obvious, but the urban penetration rate is currently less than 1%.
Li Xiang, deputy director of the City Street Light Management Office, said that the reason why it is difficult to promote it on a large scale is threefold: First, the cost of new energy street lamps is expensive, and the cost of wind-light complementary street lamps is more than 10,000 yuan per ton, while ordinary street lamps only cost several hundred yuan; The distribution of solar energy and wind energy in Xiangfan area is quite different. The summer energy is saturated, but it is not enough in winter. It needs to be supplemented with electric energy. Third, the new energy street lamp technology is still immature.
Li Xiang said that at present, the use of new energy street lamps is in the exploratory stage throughout the country. Due to the high cost, the state uses subsidies and other methods to encourage its use.
