Local communities are at the forefront of the clean energy transition in Germany, with some villages relying 100% on renewable energy. Pavol Szalai spoke to some mayors there and found that German villagers are proud of their work.
Neuerkirch and Külz are two small villages in Western Germany – of 300 and 500 souls respectively. And yet, they feel a part of something bigger that goes even beyond the country’s energy transition, the ‘Energiewende’.
“We are happy that we don’t have to be supplied by Vladimir Putin and Saudi Arabia,” the mayor of Neuerkirch, Volker Wichter, told journalists during a visit organised by the German government’s European Climate Initiative.
Neuerkirch and Külz abandoned their old fossil fuel heating system for a 100% renewable heating system – a biomass plant supplies 75% of the energy and a solar thermal plant provides for the rest. Only a few homes are not connected to the central system.
The two villages lie in the German federal state of Rhineland-Palatinate, which brands itself as a “pioneer” of the ‘Energiewende’. Apart from the biomass and solar plants, the region is also known for its wind farm. Local communities receive hundreds of thousands of euros annually for leasing their land to the turbines. The operators can afford to pay thanks to the feed-in tariff or other forms of national subsidy.
However, the local mayors there keep repeating it: “There would be no energy transition without us – we are the ‘Energiewende’.”
Sharing the benefits, transparently
Toni Christ is the former mayor of Mastershausen, a small town of 1,000 inhabitants in the rural area of Rhineland-Palatinate.
A few years ago, the municipality invested €64 million in renewable power capacity. Investors built 14 wind turbines for €50 million and a couple of solar power plants for €11 million. The new grid connections cost them €3 million.
Based on 25-year contracts, the town now cashes in at least €260,000 per year for the land lease. The revenue can climb up to €350,000 depending on how strong the sun shines or the wind blows.
Mr. Christ had to battle hard to convince his people that the wind turbines would not impact the environment. He deliberated the issue with inhabitants before the investment decisions were made. When people voiced concerns about possible harm to the bird population or about the noise generated by the turbines, he brought in experts who reassured them.
But money and transparency were the main arguments. “The high acceptance of the turbines was based on people knowing what we do with the money,” Christ told journalists. “We were transparent about everything.”
Mastershausen used the revenue to fund the construction of a fast Internet network, roads, playgrounds and a library. The town hall gives out money to families with newborns. And it funds, of course, the local energy transition via subsidies for house insulation and public transport.
“We even have English and Dutch families moving in,” Christ rejoices, adding that thanks to the Internet and improved transport, employees can work from home.
The wind turbines dominate the skyline. When the issue of aesthetics was raised, the former president of the local Rhein-Hunsrück District, Bertram Fleck, had a clear response: “An ugly view? That is a question of value. Some people like looking at wind turbines, because they represent the Energiewende.”
More importantly, the newly empowered local communities embody the kind of “grass-roots democracy” that is enabled by renewable energies, both men argue.
To be fair, the energy transition would not have been possible without the feed-in tariffs that operators receive when selling renewable power to the regional grid. But on the other hand, the wind turbines produce much more energy than the village needs. With backup sources, it could be entirely self-sufficient.
10-year return on investment
Some German towns even own their renewable power plants. Wolfhagen in the neighbouring federal state of Hesse has a 10MW photovoltaic power plant, the largest in the state, and a 12MW wind park. There is also hydropower.
Wolfhagen has been 100% powered by renewable since 2014. The town is connected to the regional grid, which supplies most of the 13,500 inhabitants, and backs up the weather-dependent renewables. On an annual basis, the town is a net exporter of electricity.
The Wolfhagen municipal utility operator (Stadtwerke) is owned 75% by the town with the remaining 25% owned by a local cooperative. “The ‘Energiewende’ works only if people are involved,” says Markus Huntzinger from Stadtwerke Wolfhagen. “That is why this cooperative works.”
Return on investment is not a concern for Huntzinger. The money that went into the wind turbines will be recovered in 10 years thanks to the electricity trader that was hired by the utility, he says.
According to Benjamin Böhme from Windtest Grevenbroich, a development and service company, one megawatt of onshore wind energy requires an investment of €1.5 million. It takes two to five years to build a turbine and go through the whole regulatory process.
The “dark doldrums”
Windtest has a testing facility for a new generation of wind turbines in the federal state of North-Rhine-Westphalia, which is also host to Germany’s largest and dirtiest lignite power plant, Neurath.
One of these turbines supplies electricity to the Bundesland on the southern border with Rheinland-Palatinate. Thomas Griese, the State Secretary at Rhineland-Palatinate’s environment ministry, admits that his state continues to depend on electricity imports for 30% of its consumption.
But 47% of electricity produced in Rheinland-Palatinate is renewable. Griese hopes that in 2030 the green dream of 100% renewable electricity will come true on the state level. At least this is the plan.
According to Griese, there are known solutions to what he calls the “dark doldrums” when the wind is not blowing and the sun not shining: power-to-gas, demand-side management, pumped storage, batteries, expansion of the grid over weather zones and offshore wind parks – all these can act as backup power, he says.
In fact, Griese seems to be more concerned by a different issue – nuclear power. “Dismantling a nuclear power plant is very expensive. It will last decades. Fortunately, we have only one,” Griese says.
