Swiss electricity from the socket is 75 percent green
The Swiss electricity supply mix for 2019 shows that three quarters of electricity from the socket comes from renewable energy sources. Their share in the Swiss production mix is lower because green electricity is also imported from abroad.
In 2019, around 75 percent of the electricity from Swiss sockets came from renewable energies. This is evident from the data collected annually by the Federal Office of Energy ( SFOE ).
According to a media release , the data published on Monday show that 66 percent of the electricity consumed comes from large-scale hydropower. 8.4 percent is generated by solar and wind energy as well as from small hydropower and biomass. In 2019, their share rose from 7.85 percent in the previous year to 8.4 percent. Around 95 percent of this was produced in Switzerland and a good three quarters were funded by the feed-in tariff system ( ESV ).
Compared to the electricity actually supplied, the shares of renewable sources in Swiss electricity production are lower: 56 percent of the electricity produced in Switzerland comes from hydropower and 6 percent from new renewable energies. In this context, the SFOE points out that the Swiss Sockets not only supply electricity from Swiss production.
19.1 percent of the delivery mix comes from nuclear energy (2018: 17.3 percent). The share in Switzerland's production mix is significantly higher at 35 percent, some of which is exported. Almost 2 percent in the Swiss delivery mix is obtained from waste and fossil fuels.
The origin and composition of 4 percent of the electricity supplied cannot be verified. Since this so-called gray electricity is only permitted in exceptional cases from delivery year 2020, according to the SFOE, large consumers are apparently increasingly switching to domestic nuclear energy. Since most of the neighboring countries do not issue any guarantees of origin for electricity from conventional power plants, Switzerland has introduced replacement certificates. Coal electricity from abroad can be declared as such and no longer has to be summarized under gray electricity. This share of coal-fired electricity halved to half a percent between 2018 and 2019. However, electricity-intensive companies recently obtained replacement certificates for electricity from fossil and nuclear sources from European power plants.
