The construction of a solar power system in 2017 was a major step towards greater sustainability for the embassy. Today, the Swiss government's buildings in Brasilia are practically energy self-sufficient as they produce almost all the electricity they need themselves. This is not self-evident in Brazil, then despite the many hours of sunshine, this renewable form of electricity production is not common in the country.
Good reasons for renewable energy
There were three key reasons why the embassy opted for a solar power system in Brazil. Firstly, Brazil receives abundant sunshine, averaging more than six hours a day and reaching up to 10 hours a day. The second reason is the rising price of electricity in Brazil. Due to climate change and prolonged periods of drought, water shortages are on the rise, and therefore less hydroelectric power is produced. As a result, prices have risen sharply in recent years, for example by 50% in 2015 compared with the previous year. The solar power system thus produces an annual energy cost saving of more than 70% so that the plant will have paid for itself in just a few years. Thirdly, the solar power generated by the embassy itself is more ecological than the electricity from the grid, as the public electricity mix is generated only partly from renewable energy sources. Therefore, the new solar power system is definitely worth the cost of installation.
