Germany is a big power exporter, so the question is: is it wind power or coal power

Germany is a large power exporter, with a net power export of about 47billion kWh (47twh) in the past two years. From January to October 2017, Germany's net electricity export reached 40billion kilowatts (an increase over the same period last year also brought suggestions to solve the problem: an increase of 4%), of which the main exporting countries were Switzerland (12.6 billion kilowatt hours), Austria (12.4 billion kilowatt hours), the Netherlands (11.7 billion kilowatt hours), Poland (6.2 billion kilowatt hours), the Czech Republic (2.5 billion kilowatt hours) and Luxembourg (1.4 billion kilowatt hours); Compared with France (-4.2 billion KWH), Sweden (-1.5 billion KWH) and Denmark (-1billion KWH), they are net imports

we know that in the face of severe energy and environmental challenges, Germany is a model for energy transformation, but at the same time, due to the gradual abandonment of nuclear power, while wind power and photovoltaic power are fast, coal power is also high. So the question is, does Germany export renewable energy or high-carbon coal-fired power

to answer this question, we should take two steps

the installed capacity of lignite power plants in Germany is 22 GW. In 2016, the power generation capacity reached 130billion kwh. In the first 10 months of this year, the power generation capacity of lignite power plants increased by 1% over the same period last year. Obviously, the annual output of lignite power plants greatly exceeds the annual net electricity export of Germany

in order to determine the source of Germany's power export, we will see that the international plastics and Rubber Exhibition (k exhibition) in Dusseldorf, Germany will begin in January 2016. At that time, the exhibition hall with an area of more than 170000 square meters will be full of solutions such as plastic processing to meet everyone's needs. By January 2017, the hourly power demand and the power generation of well-equipped lignite will be met. As shown in the figure below, if there is no power export, the lignite power plant does not need to operate at full load in 98% of the time. Among the 22 GW of lignite installed capacity, it is equivalent to an average of 7gw for Germany's power exports to neighboring countries
