The parliament of Bremen wants to oblige the use of solar energy on all new and existing buildings in Bremen and Bremerhaven. Whenever the roof surface is completely renewed, they are to be equipped with a solar system in the future. This is photovoltaics and, if necessary, also solar thermal energy. The Senate is currently examining the latter.<\/p>\n
According to the solar roof cadastre, the potential is a theoretical peak output of 1,550 MW and an annual electricity generation of 1,410 GWh. If the steel industry is excluded, this corresponds to about 40 % of the current electricity consumption in the state of Bremen. The municipal housing associations should serve as pioneers of solar energy use with tenant electricity and realise corresponding model neighbourhoods.<\/p>\n
According to Solarserver.de, this makes Bremen the Hamburg<\/a>, Baden-W\u00fcrttemberg<\/a> and Berlin<\/a> the fourth federal state to tackle a solar obligation.<\/p>\n
