Electric light means quality of living and is the basis of modern life. However, the illumination of public spaces causes huge cost of energy production and, in Germany, results in CO2 emissions of more than two million tons per year.
One third of all street lamps are older than 20 years and no longer state-of-the-art. The use of already available modern sodium discharge or LED lamps might save 2.7 billion kilowatt hours of electricity each year, corresponding to about €400 million per year.
Although the European Union is planning to phase out the use of the power guzzlers in our streets and squares gradually from 2015 on, the route to a comprehensive efficient lighting of public spaces is still long. The Berliner Energieagentur is supporting municipalities and clients from public administration and the industry in the implementation of energy-efficient lighting concepts and provides specific advice and information in the context of projects.
