According to statistics, in the case of a medium-sized city, according to more than 50000 street lamp, if all adopt the solar LED street lamp to replace, the power saving a year nearly hundred million degrees, total is 70 million yuan RMB, the entire city save coal of 50000 tons per year,
according to statistics, in the case of a medium-sized city, according to more than 50000 street lamp, if all adopt the solar LED street lamp to replace, the power saving a year nearly hundred million degrees, LED street lamp, amounted to 70 million yuan RMB, the entire city save 50000 tons of coal a year, reduce carbon dioxide emissions of 110000 tons. 6 billion tons of global carbon dioxide emissions and 460 billion kilowatt hours of electricity. The digital equivalent of India's annual electricity consumption, Japan's annual electricity use half or a quarter of the annual electricity consumption in China. Jinan city as an example to have been investigated. Jinan 2000 administrative villages all install solar street lamp, according to a village 20 lamp ( 30 w) To calculate. Capacity of about 1. 2 million KWH, equivalent to a year can save more than 480 tons of standard coal, to reduce emissions about 336 tons of ash, carbon dioxide is about more than 900 tons, about 36 tons of sulfur dioxide emission reduction, reduction of pm10 about six tons, really contributing to real rural green ecological construction.
