Electricity, gas and water are mainly supplied to Berlin homes by three different utility companies – Vattenfall, Berliner Gaswerke AG (GASAG) and Berliner Wasserbetriebe. In most Berlin homes desk lamps or toasters are powered by electricity from Vattenfall but more and more Berliners are now opting for green electricity providers.

Companies that supply 100 percent environmentally friendly power include Greenpeace Energy, LichtBlick, Germany’s largest independent power supplier, and Naturstrom.

If your apartment is heated by natural gas instead of community heating, you probably are a customer of the GASAG. Their first gas lanterns began illuminating Berlin city center in 1847. Today, GASAG and its subsidiaries in the Berlin-Brandenburg region supply more than 700,000 customers with natural gas, biomethane and green electricity.

The Berliner Wasser­be­triebe supplies 3.8 million people in and around Berlin with potable water and also takes care of waste water. Currently, one liter of drinking water costs about 0.5 cents, an unbeatable price compared to water from the supermarket..
