Germany_Moving_Towards_100__Renewable_Energy

September 6 was a historic day for the German energy industry, with the liberal-conservative government headed by Angela Merkel vowing to reverse the country's position on nuclear energy – and keep Germany's nuclear plants on, rather than shut them down.

This controversial decision, provoking strong protest, was unnecessary, as two special days show:

For most Germans, July 14 was unspectacular, as temperatures climbed above 30 degrees Celsius. The day set a record not in temperature but in solar energy. For the first time, combined electrical output of solar panels in Germany was more than 50 percent of the output of the nation’s 17 nuclear plants operating at the same time.

Renewable energy had passed a critical threshold, with the nation taking another step in the transition from nuclear and coal to renewable energy. This came seven months after Germany had received an unusual Christmas present. Heavy winds on December 26 delivered free electrical energy, and wind turbines produced up to 20.100 megawatts of power, pushing the price for electricity into the negative: It cost up to 20 cents per kilowatt hours to produce power. Coal plants had to pay for power instead of selling it.

The two days sent a signal – the goal of providing Germany with 100 percent renewable energy is reachable.

For decades the environmentalist movement, blossoming wind and solar industries, as well as Germany’s Green Party dreamed of switching completely to renewable energy. Now political support reaches across the political spectrum. Even the conservative minister for the environment, Norbert Röttgen of the Christian Democratic Union, supports it.

And the development is widely seen as technically realistic. Within the international context, Germany acts as an early adopter: Like the first user buying an iPhone or Google cellphone with Android, the nation pays a premium price, but also figures out the technology, including downsides and upsides. For other countries, the technology will be tried and tested and, due to economies of scale, much cheaper.

Germany carries the benefit of gaining expertise in a growing market. Indeed, while the leading argument for pushing renewable energy has long been action against climate change and reduced carbon emissions, the cases for energy security and job creation follow closely.

Development has not been easy. Germany is not the best suited for renewable energy, lacking volcanic energy like Iceland or a long coast with strong winds like Ireland, Great Britain or Morocco. It does not have as much sunlight as Spain, California or North Africa. Unlike Norway which powers most of its electricity for 4.8 million citizens through hydro-energy, Germany provides power for more than 80 million people and an industrial output surpassed only by China.

One lesson from this – if it can be done here, in the heart of Europe, it can be done anywhere. In 2008 Germany relied on imports of coal, gas, oil and uranium for 70 percent of its primary-energy production.

The policy goal set in the late 1990s was 10 percent renewables. In 2009, 9,800 megawatts of solar power had been installed, as well as 25,78 gigawatts of wind. Currently, 16 percent of electricity is produced by renewable sources. And the experts suggest that it’s possible to go from 16 to 100 percent. The German federal government recently updated its projection of renewables production for 2020 from 20 to 30 percent. The Bundesverband Erneuerbare Energie, an association of producers of renewable energy, goes further, claiming that 47 percent is possible by 2020.

The scientific advisory board to the German government, the Sachverständigenrat für Umweltfragen, SRU, produced its own study, mostly performed by the German Institute for Air and Space, or the DLR. Researchers calculated hour by hour throughout the whole year, comparing averages of solar and wind production to balance them with spikes of demand. The results were clear: Not only is it technically possible, but also economically viable. Increase in investment upfront is set off by savings from buying less coal and gas later.

The federal office for environment, Umweltbundesamt, also published a study focusing on regional strengths and connections: While wind is strong in the north and east, solar is stronger in the south, and there are other parts where biomass and hydro-energy can be used for storage. In total, these differences can be used to balance energy production throughout the year.

Other countries examine how Germany pursues energy independence. The most important building brick of the German policy for renewable energy is the feed-in-tariff. It guarantees a fixed price for renewable energy, which decreases according to gains in efficiency. This simple concept increased investment in renewables and has been adopted by 18 states of the European Union as well as Japan, Brazil and China. Germany avoided pumping about 74 million metric tons of carbon dioxide into the atmosphere in 2009, and the environment ministry touts another side benefit – nearly 300,000 new jobs in clean power.

The tricky question, of course, is costs. Critics like the British environmentalist George Monbiot argue that the feed-in-tariff costs too much. Indeed, In Germany, electricity prices have soared more than 60 percent over the past decade. But Germany’s environmental ministry says the tariff is responsible for less than a tenth of that increase, or about $3 per month for a typical household.

The price is worth it – considering that Germany not only tries these technologies out as an early adaptor, but shapes a worldwide market.

McKinsey & Company and the Imperial College co-authored “Roadmap 2050,” a study commissioned by the European Climate Foundation, on methods for achieving a “prosperous, low carbon Europe.” The findings: Europe can follow the German example and be powered completely by renewable energy, by developing a smart electrical grid, with strong transmission lines between North and South. Currently between France and Spain, but also Italy and its neighbors, these are lacking. Without these lines, it is impossible to share wind and solar power across Europe.

Despite many arguments for renewable energy, the topic remains highly contested. While Röttgen, minister for the environment, is all for it, he faces opposition from those in his party who favor nuclear energy. With Merkel's decision for the prolonging of nuclear, Röttgen has lost the battle. Most likely, federal courts must consider the matter as well, as opposition parties have already declared their intention to call on the courts.

Germany had decided to cease nuclear power gradually, but the conservative-liberal coalition’s change in policy would mean a certain end for the boom of renewables: Baseload power of large nuclear and coal power stations leaves little room in the electric grid for more volatile solar and wind. Returning to nuclear power would be highly profitable for four large utilities, with profits ranging around €1 million per day per nuclear plant. The topic promises to remain controversial this fall. But the voice of the public is clear, with more than 80 percent supporting renewables in a recent poll by FORSA.

Meanwhile the home base of the federal government has already switched to renewables: Offices of the parliament have solar-panel rooftops, the Reichstag has its own geothermal heating plant. Berlin is the only capital in the world powered by 100 percent of renewable energy. Whether the rest of the country follows suit will be decided in the months ahead. The decision is about political will, not technical or economic feasibility.
