Canton Zurich identifies untapped potential for solar power
At the end of 2021, around 12,600 photovoltaic systems in the canton of Zurich will have produced around 0.3 terawatt hours of electricity. This is the result of an analysis by the cantonal statistical office. It locates great untapped potential for the further expansion of solar energy.
Falling prices for solar installations have fuelled the construction of new photovoltaic systems in the canton of Zurich, as an analysis by the cantonal statistics office shows. According to this, there were at least 12,600 active photovoltaic systems in the canton at the end of 2021. Almost all of them were installed after 2010, according to the data. They produced about 0.3 terawatt hours of solar electricity per year, which is roughly equivalent to the annual electricity consumption of the canton of Appenzell Ausserrhoden.
Despite the increase in installations, the analysis finds that there is still a great deal of untapped potential for solar power. About half of all Zurich systems are installed on single-family homes. There is still a need to catch up with multi-family houses and buildings that are not used for residential purposes. The latter also offer space for larger systems with a higher installed capacity.
The analysis identifies further potential in new buildings. When the new cantonal energy law comes into force in September 2022, all new buildings will have to contribute to covering their electricity demand. It can therefore be assumed that new systems will be installed in the coming years.
The Canton of Zurich wants to achieve zero greenhouse gas emissions by 2040 – or by 2050 at the latest. Accordingly, according to its own information, it attaches great importance to the use of the existing potential for renewable electricity production. ce/ssp
