Germany’s Dangerously Flawed Energy Policies

There are two options for Berlin's energy strategy: Either to convert coal-fired power plants into gas plants or to buy foreign nuclear power, perhaps even to build new nuclear power plants. A column by Hans-Werner Sinn.

French President Emmanuel Macron thinks an overhaul of Germany’s economic model is overdue. As far as energy is concerned, he is probably right.

While France produces over 70% of its electricity in nuclear power plants and is trying to convert to electric vehicles (EV) running on nuclear energy, Germany relies on wind farms and other forms of green energy, and plans to phase out nuclear power by 2022, and coal power by 2038. Yet the attempt to turn the wheels of German industry with wind faces growing political resistance, as the country is already littered with so many wind turbines – some of them nearly 250 meters (820 feet) high – that even its most beautiful vistas are coming to resemble industrial landscapes.

Farmers and forest owners, of course, have welcomed the opportunity to convert their land to industrial sites. Usually, only landowners on the outskirts of big cities enjoy such windfalls, but with legislation facilitating the erection of wind turbines in rural areas, German farmers and forest owners have struck gold.

Potential of solar and wind is limited

Nonetheless, the expansion of wind turbines is stalling, owing to a growing chorus of citizens who object to the destruction of the natural environment. Protest movements against what is seen as environmental vandalism are sprouting like mushrooms. Even the German Nature and Biodiversity Conservation Union (NABU) is beginning to reconsider its position on wind turbines, owing to the loss of insects, birds, and bats on a massive scale. And while solar energy and biogas plants still represent potential alternatives to wind, they are also facing limits, given that Germany is not a sun-kissed country, and the table-or-tank problem – whether to use land to grow food or fuel – represents a serious ethical dilemma.

The main problem is the volatility of wind and solar energy. Sometimes there is too little electricity, and sometimes there is too much. If the wind isn’t blowing and the sun isn’t shining, conventional power plants must shore up the electricity supply. Hence, no matter how many wind- and solar-powered plants Germany builds, it still cannot dismantle its conventional plants.

Moreover, when wind and solar generate too much electricity, they regularly drive the price of electricity below zero. These distortions will grow dramatically if the market share of wind and solar power, currently at 25%, increases beyond 30%, because production spikes will then begin to overshoot electricity demand.

Electric vehicles won’t help

Worse, as the market share of directly usable wind and solar power approaches 100%, so, too, does the proportion of surplus energy. Even if Germany and its neighbors were to create a perfect electricity network stretching from the Alps to Norway, with as many pumped-storage plants as geologically possible being built in the participating countries, the market share of wind and solar power could not surpass 50% without ever-larger portions of the excess current peaks being dumped or degenerated by a change in the entropy level (conversion into heat or gas).

Confronted with this problem, many people point to electric vehicles as a solution. There can be little doubt that EVs are the future, given the European Union’s massive regulatory interventions in the automobile market (at France’s urging) to make it so. But, far from alleviating Germany’s energy problems, EVs will make them even worse.

Drawing an ever-greater proportion of their energy from green sources, German households already pay the highest electricity prices in Europe, ahead of Denmark, which also relies heavily on wind power. If the German transportation sector is forced to become electric, the resulting increase in power demand will lead to further price increases, inflicting sustained damage on the country’s industrial base.

At odds with France

If Germany wants to keep energy prices constant, it must temper its green ambitions. But without further reducing its carbon dioxide emissions, it will miss its binding EU targets for reducing greenhouse-gas emissions and have to pay fines to the EU.

There are only two ways out of this quandary. The first is to convert existing coal-fired power plants into gas plants, which produce only half as much CO2. That, at least, would allow Germany to reduce its annual CO2 emissions from 900 million to 770 million tons. This option would require new gas pipelines similar to Nord Stream 2, a joint German-Russian project that already faces stiff resistance from the European Commission and particularly France. Indeed, just a week after signing a new Franco-German friendship treaty in January, Macron suddenly stopped supporting German Chancellor Angela Merkel’s effort to block the EU asserting control over the pipeline, even though it crosses no other member state’s territory and would not normally be subject to EU regulation.

Germany’s second energy option is to buy foreign nuclear power or start building new nuclear power plants on its own territory. Germany would tacitly accept the former, but for the latter to happen, it would have to undergo a politically painful process of returning to reality and retiring the generation of politicians who have insisted on a nuclear phase-out. In 2009, Sweden, the first European country to abandon nuclear power after the Three Mile Island accident in 1979, reversed its decision. Germany may have to do the same at some stage. While it has already lost most of its own nuclear expertise, the country wouldn’t have to look far for new nuclear-power plants: they’re available for purchase from France.
