The restructuring of the German power generation landscape is progressing in leaps and bounds. In 2017, renewable energy sources already accounted for around 36 per cent of electricity consumption. This share will continue to increase and, according to plans by the federal government, reach 65 per cent in 2030. The figures show that the influence of renewable energy sources on our power supply is growing. The weather is an ever more important factor here. When there is lots of wind and sun, much more green electricity may be generated than consumed at that moment. If weather conditions are unfavourable, the electricity must come from conventional sources – or looking further to the future, from storage facilities.
This makes sector coupling all the more important – i.e. converting electricity from renewable energy sources into other forms of energy and enabling it to be used by other sectors such as industry, heating or transport. The advantages: On the one hand, this would efficiently reduce the “ecological footprint” of our economy. Furthermore, the technology offers a way of enabling fluctuating renewable energy to be stored.
