The German Reichstag (1/10)

Visitors walk inside the glass dome of the German Reichstag parliament building in Berlin. The building's energy system is based upon a mix of solar energy, geothermal power, combined heat and power, biofuel generators, and innovative ventilation. Special insulation limits heat loss.
More than 80 percent of electricity needed is generated internally. A geothermal installation cools the building in summer and provides heat in winter. Annual CO2 emissions are thus reduced from 7,000 to less than 1,000 tons. (Photo: Reuters)
