Germany’s Nuclear Phase-Out & Rising Coal Consumption

Brown coal electricity production in Germany rose last year to its highest level since 1990, despite a nationwide campaign to shift to green sources of energy. Between 2011 and 2015, Germany will open 10.7 GW of new coal-fired power stations, with the expected annual electricity production to exceed that of existing solar and wind. Nuclear proponents blame the construction of coal plants on the post-Fukushima nuclear phase-out, but the truth is investment decisions for these power plants were made much earlier from 2005 to 2008. In fact, in order to fill the void rendered by shuttering its nuclear fleet, Germany's former Minister for Energy and Economics said in 2009 that the nation have to build eight to 12 coal power plants. This is exactly what he got.

January 29, 2014 | Robert Wilson,

In September 2012 Germany's Environment Minister opened a new lignite power plant, arguing the following: “If one builds a new state-of-the-art lignite power plant to replace several older and much less efficient plants, then I feel this should also be acknowledged as a contribution to our climate protection efforts.”

Peter Altmaier is not alone, recently the climate benefits of Germany's new and apparently ultra-efficient coal power plants have been extolled not only by manufacturers such as Siemens and power companies including RWE, but even some of the German nuclear phase-out's most vocal proponents.

We are also now seeing increasing numbers of people suddenly noticing an uptick in coal power, and deciding it has little to do with Germany's decision to move away from nuclear energy. These arguments require both an alternative arithmetic and an alternative history. Here’s why.

In the aftermath of Fukushima, Germany prematurely shut eight nuclear power plants. Respect for arithmetic and the intelligence of my readers dictates that I do not explain why this should lead to an increase in carbon dioxide emissions. However, the relationship between Germany's nuclear phase-out and the construction of new coal power plants deserves an explanation.

Between 2011 and 2015, Germany will open 10.7 GW of new coal-fired power stations. This is more new coal capacity than was constructed in the entire two decades after the fall of the Berlin Wall. The expected annual electricity production of these power stations will far exceed that of existing solar panels, and will be approximately the same as that of Germany's existing solar panels and wind turbines combined. Solar panels and wind turbines, however, have expected life spans of no more than 25 years. Coal power plants typically last 50 years or longer. At best you could call the recent developments in Germany's electricity sector contradictory.

These new power plants are sometimes blamed by nuclear proponents on the post-Fukushima decision to shut all nuclear power plants by 2022. This is a myth. Any large piece of infrastructure takes a long time to build, and Germany simply could not respond to Fukushima by building new coal power plants at this scale and speed. Investment decisions for these power plants were made in 2005 to 2008 (see table 2 here). In response, supporters of the nuclear phase-out claim that construction of new coal power plants had nothing to do with Germany's decision to phase-out nuclear energy. This however is historical revisionism.

A terse history lesson: in the year 2000, the government of Gerhard Schröder announced that all of Germany's nuclear power plants must close by 2022. The law was passed in 2002. This policy was revised by Angela Merkel in September 2010 to extend the lives of nuclear power plants so that the phase-out would occur by 2032. Then after Fukushima, Merkel wisely or opportunistically ­– take your pick – decided to revert largely to the earlier phase-out plan, closing eight nuclear power plants immediately and ruling that all would close by 2022.

The policy to phase out nuclear power was vital to the decisions to build new coal power plants. Closing down a quarter of your electricity generation leaves a gap that must be filled by something, and Germany realized it would largely have to be filled by one thing: coal. This is more or less beyond doubt because Germany's then Environment Minister Sigmar Gabriel said so. Gabriel, now Germany's Minister for Energy and Economics told climate scientist James Hansen that Germany had to build new coal power plants because of its nuclear phase-out, and stated elsewhere that Germany would have to build eight to 12 coal power plants to replace its nuclear fleet.

And this is exactly what he got. In the first half of this decade Germany will open nine new coal power plants.

  • It would be much wiser for Germany to build thorium (LFTR) power plants, which are safer, disaster-proof, and much more efficient than fossil burning plants.

  • Germany’s paralyzing fear (and brainwashing by the Greens) has led them to this oxymoron:  the Greens claim to be supportive of the environment but their politics has led to the shutdown of nuclear power and the gap is largely filled with lignite coal—the very worst kind.  Germany believes that wind and solar offer a panacea but they pay a very heavy price in subsidized electricity rates that hurt consumers and their carbon dioxide production is increasing.  So much for emotion ruling energy decisions.  In an effort to be purists, they are actually making things worse.

    • China and India are leading the world in thorium research.  Germany should realize that anti-pollution devices still can’t cleanup coal-burning enough, and wind and solar are nothing but a loss in the long run.

  • China is leading the world in lignite burning and CO2 polluting.
    They added 300GW if new coal (not the highly efficient German coal) in the last 4 years. That’s all of Germany’s capacity.
    Germany is instead burning less coal due to higher efficiency and will meet its co2 reduction goals as it has demonstrated in the past.
    France will follow suit and reduce it’s nuclear generation to 50% till 2020-2025…
    There are reasons for that and you can find them if you try to look beyond nuclear.
    If you think thorium will help just watch China fail that path. You could also look at high altitude solar or wind energy (kitegen, some German rigid wing designs and strato solar…)
