The share of solar and wind power has also been rising in the U.S. for years now. While Europe already produces so much electricity from renewables that the systems have to be shut down at times and storage technologies have therefore moved to the centre of research, U.S. researchers are also starting to tackle the issue.
Curtailment is the horror term for the renewable energy sector. If so much solar and wind energy is produced that the grids can no longer absorb the electricity, the plants must be switched off. This can be remedied by innovative technologies such as storage and batteries. In Germany, the topic has been the subject of a massive public debate in recent weeks, not least because the
