The share of renewable energies in the German electricity mix has increased in the past year, for the first time, more than 40 percent. According to calculations of the Fraunhofer Institute for Solar energy systems (ISE) – produced Wind, Solar, biomass and hydro power plants in 2018, a total of nearly 219 terawatt hours (219 billion kilowatt-hours) of electricity, up by 40.3 percent of the total net electricity generation.

especially Solar and wind power plants delivered, according to Fraunhofer ISE significantly more electricity to the grid as of 2017; at that time, the renewable sources had a total of 38.2 percent share. In return, in particular the production of Gas – and coal-fired power plants declined; and the brown coal-fired power plants, however, hardly.

The net electricity generation is the electricity, the power plants into the public grid feed-in: after deduction of their own electricity needs, their own energy losses and without the need for industrial self-generation of electricity. The Freiburg-based Fraunhofer Institute bases its calculations on data from the electricity exchange, EEX, of the network operators and the Federal Statistical office.

“The share of Renewable has risen now and 2018, but it’s not happening fast enough,” said Bruno Burger, Professor at the Fraunhofer ISE, the MIRROR. “If Germany continues with this speed, we will miss our targets for 2030”.

The Federal government has made to increase, by 2030, the renewable electricity share to 65 percent. With the current energy policy, this was not achieved, however, says Burger. “The photovoltaics will be slowed down” – although the once extremely high state-guaranteed feed-in tariff for solar installations had fallen dramatically.

Nevertheless, in 2018 and shot in the production of solar power by 16 percent, according to Burger, mainly due to the hot and dry summer. In the first week of July about solar modules, two-fifths of the entire German net delivered electricity generation.

wind farms, which in the summer often lull experience, running in the Winter is in full swing. In the week to Nicholas, you provided more than 60 per cent; over the year as a whole, they contributed to 2018, for the first time, more than a fifth of the electricity mix. With a production of 111 billion kilowatt-hours of wind power, Germany’s second most important source of power.

number one is still the brown coal 131 terawatt-hours. Although the prices of allowances for emissions of carbon dioxide (CO2) increased in the course of the year strongly, particularly CO2-intensive production of brown coal in electricity only two percent. The main reason for this is that electricity from brown coal in Germany, is cheaper to produce than from other fossil sources such as natural gas. And Germany’s largest brown coal fossil Romer, the energy giant RWE, already for several years in advance of cheap CO2 certificates.

For his own supply could get by on Germany is probably with significantly less brown-coal electricity. According to the Fraunhofer ISE-Pay exported electricity generators in 2018, a net of more than 45 billion kilowatt-hours abroad. “The brown coal-fired power plants in the Rhine area close to the border. You can move directly into electricity via high-voltage lines in the Netherlands,” says Burger. “We have to get out to 2030 from the brown coal, otherwise we can’t get the climate goals.”

at the beginning of February, the Federal government appointed the coal Commission is to submit with representatives from politics, business, economic, and environmental associations of their master plan to the Coal phase – out. A possible closure of all brown coal-fired power plants and mines up to 2030 is considered highly unlikely.
