THE GERMAN FEDERAL GOVERNMENT WANTS TO ESTABLISH THE AGE OF RENEWABLE ENERGIES BY 2050 AND QUIT USING NUCLEAR ENERGY BY THE END OF 2022, AT THE LATEST.

Even without nuclear energy, the emission of greenhouse gases is to be reduced 40 percent by 2020 and at least 80 percent by 2050 (compared to 1990). The share of solar energy, wind, and other regenerative energy sources in the power consumption is to be stepped up to at least 35 percent. Currently, this share is about 17 percent.

Power from wind plays an important role, especially offshore wind energy from the North Sea and Baltic Sea. Other sources include hydropower, photovoltaics, geothermal energy, and biomass.

Renewable energies must be combined with modern conventional power plants and power storage units to form a stable supply system. The grid feed-in, which can fluctuate substantially, must be duly controlled. To ensure reliable supply, it must be possible to buffer energy. This is where new, modern energy storage systems come in.

 

As the power grids are currently not designed for the transport of renewable energies, the grid development must be accelerated. Moreover, intelligent grids and storage units must be implemented, and intelligent power meters must be used.

By 2050, the goal is to cut the need for primary energy by 50 percent. This necessitates massive energy savings and increased energy efficiency. This is partly possible by employing high-end drive, closed-loop, and open-loop technologies.

Still, the affordability, cost efficiency, and effectiveness of all measures must be guaranteed. Energy suppliers need to compensate the wind-up costs resulting from the exit from nuclear energy with potent measures to increase the effectiveness and efficiency. Another challenge is the much higher complexity in the construction, operation, and maintenance of all network components.
