Street lighting is an essential public service typically provided by public authorities at the sub-national and municipal level. Cities are increasingly investing in energy-efficient street lighting systems to replace or enhance their outdated systems. While reliable and bright public lighting reduces accidents and crime and allows for economic activity after sunset, modern energy-efficient street-lighting technology can also lower energy consumption as well as operation and maintenance costs significantly. Many different models have been developed world wide to deliver energy-efficient street lighting projects, including public-private partnerships.
