Photovoltaics

The climate protection programme of the German government includes an expansion target for renewable energies to 65% of gross electricity consumption until 2030, with an increase of minimum 80% in 2050.

Photovoltaics plays a major role in our sustainable energy future. On sunny days, photovoltaics can temporarily cover up to 50% of our current electricity consumption. Averaged over the entire year 2019, photovoltaics covered 8.2% of gross electricity consumption in Germany.
