Remember the big, somewhat bulky Mercedes Benz cars of the early 1990s? State-of-the-art at that time, they left their competitors behind on Germany\u2019s autobahn. Mercedes is still here today, but the autobahns are not what they were: Germans fear that two decades of neglect after reunification might have seriously damaged the country\u2019s once superb infrastructure.<\/p>\n

Similarly, Germany once possessed one of the world\u2019s most well engineered power systems. Yet in 2014 the country urgently needs new power grids \u2013 or \u201cstromautobahnen\u201d (electricity highways) \u2013- to keep supply stable in the face of growing proportions of volatile renewable energy. There are concerns over<\/a> whether it can keep pace with the phase-out of nuclear power, a decision taken in the wake of the Fukushima disaster three years ago. Nuclear helps to stabilise demand on the grid but eight out of 17 reactors have now been shut down, with the rest due to close by 2022.<\/p>\n

Der energiewende<\/h2>\n

Electricity generation from renewables has risen lately to new unprecedented highs, overtaking lignite coal to become<\/a> the number one single source in the nine months to September 2014. This is part of the government\u2019s policy of \u201cenergiewende\u201d \u2013 the rapid transformation of the power system towards green energy. The stated target is for renewables to provide 55% to 60% of German electricity by 2035 \u2013 among the most ambitious in the world.<\/p>\n

The changing German energy mix<\/strong><\/p>\n

But there are doubts as to whether it is realistic, and whether it might turn out to be harmful for Germany\u2019s industry. One indicator is that electricity tariffs have almost doubled<\/a> since 2000, for example. Meanwhile CO2<\/sub> emissions have not decreased, but actually increased<\/a> over the last few years because coal-fired power has been on the rise while nuclear wanes.<\/p>\n

It is also no secret that Germany\u2019s energy companies are not<\/a> doing well, as pointed out by the chief executive of French rival EDF recently in a general attack on the state of the German energy sector. Both RWE and E.ON have had to accept huge write-downs in the value of their domestic nuclear and fossil-fuel-powered assets. Is Germany thus in the process of sacrificing the once famous reliability of its power sector for little more than problems? And if so, what might be the way forward? Back to nuclear energy?<\/p>\n

The policy only Germans understand<\/h2>\n

The disastrous state<\/a> of Germany\u2019s repositories for radioactive waste such as Brunsb\u00fcttel and Asse in the north are not encouraging. And public support for both renewables and nuclear phase-out is still great<\/a>. But further afield the German decision to live without nuclear has perplexed many observers. To the great amusement of the participants at a business conference in Berlin in 2010, Vladimir Putin offered<\/a> the Germans firewood from Siberia to heat the country once its nuclear power stations had been switched off. Clearly the energiewende has not exactly impressed the Russians.<\/p>\n

How about others? Japan, which has more reason to back the energiewende than almost anyone, is relaunching<\/a> its nuclear programme. The United States is happy with its shale gas, and at home in Europe, not many countries have joined the Germans either. On top of this, G\u00fcnther Oettinger, Germany\u2019s accomplished top official in the European Commission, is no longer responsible for energy. It would seem then that Germany\u2019s energy policy has not many influential supporters left.<\/p>\n

The tech dimension<\/h2>\n

There remains the idea to sell German-engineered green tech to the world. Siemens is a world leader in renewable technology, for example. Yet the technical level of difficulty is not necessarily high enough to serve as the basis of a high-tech industry in which the Germans can have a competitive advantage in the long term \u2013 it is too easy for other players to fabricate equivalent structures. This was illustrated by the Desertec project to build huge solar parks in the North African desert. It collapsed<\/a>, where Siemens had already walked away a few months earlier. It wasn\u2019t seen as a big deal for the Germans, since many components for the project may have come from China anyway. If the same thing happened with the production of wind turbines, however, it would be a serious setback to the idea of Germany relying on green tech as a base for future industrial production because it would be undercut by other countries who could make the same products more cheaply.<\/p>\n

\"\"<\/a><\/figure>\n

But most things in life have two sides. The great hope is that German engineering will once more surprise the world with technical solutions for difficult problems in difficult times. The central issue is the power grid. One of the key challenges is to find an electricity storage mechanism<\/a> that can allow a quick and flexible response to changes in the amount of wind and solar power \u2013 currently the availability drops when the wind stops blowing or the sun stops shining.<\/p>\n

Another big challenge is persuading consumers to react more flexibly to these ups and downs, most likely by altering the price of power accordingly. Solve these problems and the fact that renewables have no fuel costs would make them a serious alternative to other energy sources.<\/p>\n

The power grid and its components, not Putin\u2019s firewood, could become the \u201cwunderwaffe\u201d<\/a> (\u201cwonder weapon\u201d) able to solve Germany\u2019s energy problems. But these new techniques need to be affordable, otherwise the effect will be negligible and only perpetuate the existing problems.<\/p>\n

To end on a positive note, there is one much less debated issue around the country\u2019s nuclear phase-out programme. If Germany sticks with its chosen course, the development of third-generation nuclear plants will be in the hands of countries such as France, Britain and Poland. But German industry is famous for its ability to occupy profitable technological niches. Given that there are many nuclear power stations to be dismantled, and a lot of nuclear waste already rotting in the country, the Germans will have to find solutions to deal with it. If they still are the engineers they used to be, they will. This could become a very lucrative thing to then sell to the rest of the world.<\/p>\n
