By 2030, 65 percent of the nation’s energy needs must be met by renewable sources such as wind and solar, in line with the ambitious energy transition target. Hamburg outlined in its own climate protection master plan how to promote the phase-out of fossil and nuclear energy sources. The Hanseatic City wants to cut CO 2 emissions by at least 80 percent by 2050. Solar energy is one of the most important sources of energy, both here on the Elbe and nationwide to bring about a revolution in energy: along with wind energy and biomass power generation, it is one of the three most important sources of renewable energy.
In 2017, more than 36 percent of Germany’s electricity consumption came from renewable energy sources. Of the total green electricity production in Germany in 2017, more than 18 percent came from photovoltaic systems. To meet the ambitious energy transition goals, PV systems need to be upgraded to generate 5 gigawatts of electricity per year, according to a study by the Fraunhofer Institute. We are currently at 1.75 gigawatts. The Renewable Energy Act and the Hamburg Solar Offensive, which we at HAMBURG ENERGIE are promoting significantly, are promoting the construction of more solar energy systems here in the Hanseatic city. The big advantage: flexibility. For example, compared to increased use of wind power, it is much easier to install new photovoltaic systems. While only about 2 percent of Germany’s territory is suitable for wind power systems, solar power systems can be flexibly configured in many locations, be it an open space system or on rooftops.
