Simply Renewable: From the Alps to the North Sea

The plateau in the Berchtesgaden Alps, with its Alpine roses and Swiss pines, is as peaceful as paradise. Hikers sit on the terrace of the Traunsteiner Hütte mountain lodge, their heavy backpacks propped up against the wooden 
tables. They are quietly enjoying wheat beer and chamois soup. It was the sun that cooled their drinks and heated their meals, for (apart from an emergency diesel gener­ator) landlord Thomas Krüger gets all the energy he needs for his many guests from photovoltaics and solar heat without emitting a gram of the greenhouse gas CO2. Up here you can marvel at one facet of a revolution that few other countries can offer: the transformation of the energy system.

Germany’s first offshore wind farm, called Alpha Ventus and located 45 kilometers off the coast, supplies electricity for 70,000 households. Tourists can get a close-up view by ship or on a scenic flight. Or in the heart of Berlin: if you take a guided tour of the Federal Press Office, you will learn how offices and conference rooms can be air-conditioned with hot water – using sophisticated technology. Hikers might like to climb up to the pumped storage power plant at Wehr in Hotzenwald; it stores energy in the form of water in an artificial lake, like a gigantic battery. “The use of traveling,” the British author Samuel Johnson once said, “is to regulate imagination by reality, and instead of thinking how things may be, to see them as they are.” That sounds like a piece of fatherly 
advice for tourists: leave the well-trodden travel routes behind, and if you have a pre­judice against radical ideas on eco-friendly energy, at least take a look at how it works in reality.

  • Around 25% of electricity already comes from green sources, and the Federal Government plans to increase this to at least 80% by 2050. Scientists even believe that 100% is possible. And much earlier, too.

Leadership in Climate Policy

Other nations want to follow Germany’s example. The German Renewable Energy Act (EEG), which accelerates the development of green power plants by charging all consumers a levy, has been an export hit: 19 of the EU’s 27 member states are now using this model for their own energy transformation. And why shouldn’t the energy transformation succeed? Nature supplies enough fuel: theoretically, every single renewable source could cover the world’s appetite for energy several times over. Recent studies show that the energy transformation can also succeed financially. Calculating up to the year 2050, the costs will not be higher than if we stick with nuclear energy and coal. Even if electricity prices initially go up, they will fall by about 30 percent in the medium term. So in the end the result will be a clear advantage for consumers and industry. The Germans are currently passing through stage two of their energy transformation: they are becoming self-sufficient. Instead of feeding the power generated by the 1.1 million solar-panel-fitted roofs into the grid at subsidized prices, they are increasingly using it themselves. After all, a kilowatt-hour from the roof can now be had for twelve cents, whereas a kilowatt-hour from the local utility costs almost 30 cents.

Soon they will be recharging their electric cars – and storing surplus solar power overnight in batteries in the cellar. You might say that what landlord Krüger practices up in the Alps is now being continued by millions of people down in the valley.

The International Climate Stage: IRENA

The International Renewable Energy Agency (IRENA) is an intergovernmental organization dedicated to promote the widespread and increased adoption and sustainable use of all forms of renewable energy. It was founded in Bonn in 2009, and since its founding Germany has played a key role in developing its policies.
