Depending on the technology used, electricity from renewable energies can be produced significantly cheaper than electricity generated in conventional power plants. This is shown by a study by the Fraunhofer Institute for Solar Energy Systems ISE. Accordingly, electricity from gas turbines and hard coal-fired power plants is the most expensive to produce.

 

Photovoltaic systems convert solar radiation into electrical energy using solar cells. In a global comparison, Germany was recently one of the leading countries, along with China, the USA and Japan, in the use of photovoltaics to generate electricity.

 

In Germany, the installed capacity of photovoltaic systems increased continuously. In 2020, photovoltaic systems with an output of around 54 gigawatts were installed in Germany. The electricity generated by this amounted to around 51 terawatt hours of electricity in the same year. The largest capacities for generating solar power are in the south of Germany. Bavaria is currently by far the federal state with the largest capacities, followed by Baden-Württemberg.

  • China and the Neijuan of systematic overinvestment: State capitalism as a growth accelerator and structural trap

    ▶️ China and the Neijuan of systematic overinvestment: State capitalism as a growth accelerator and structural trap

    Beijing protects its monetary sovereignty and clearly opposes stablecoin projects by global tech giants. | China's regulators are relying on control over foreign digital currencies to preserve monetary policy autonomy. | The promotion of the digital yuan is at the heart of the strategy to strengthen state oversight and financial stability. | | Strict rules aim to contain risks such as capital flight, market manipulation, and data protection gaps. | The measure has geopolitical dimensions and reduces the influence of Western tech companies in payments. | Tech companies face technological hurdles and legal barriers that complicate their stablecoin plans. | Consumer and market interests are being weighed against national security and oversight needs. | In the short term, this mistrust can slow innovation; in the long term, it strengthens Beijing's control over money flows. | International cooperation is becoming more important, but China prefers clear rules and national solutions.
