In the first half of this year, the electricity consumption of urban public lighting in cities and counties was 41. 57 million degrees. compared with the same period before the energy-saving renovation in 2010, it saved 8. 7 million degrees. It is understood that Hainan province has taken the lead in carrying out energy-saving renovation of urban public lighting facilities in Qionghai city, Hainan province since July 2011. By December 2012, cities and counties in Hainan province have basically completed the energy-saving renovation of urban public lighting facilities.
