Coal Casts Cloud over Germany’s Energy Revolution

The energy market in Germany’s saw a spectacular change last year as renewable energy became the major source of its electricity supply − leaving lignite, coal and nuclear behind.

But researchers calculate that, allowing for the mild winter of 2014, the cut in fossil fuel use in energy production meant CO2 emissions fell by only 1%.

Wind, solar, hydropower and biomass reached a new record, producing 27.3% (157bn kilowatt hours) of Germany’s total electricity and overtaking lignite (156bn kWh), according to AGEB, a joint association of energy companies and research institutes.

This was an achievement that many energy experts could not have imagined just a few years ago.

Lowest level

Beyond that, Germany’s primary energy consumption – which includes the energy used in power generation, heating and transport − fell to its lowest level since reunification with East Germany in 1990, AGEB reports.  It shrank by 4.8% compared with 2013.

Estimates by AGEB indicate that Germany’s CO2 emissions will have fallen in 2014 by around 5% compared with 2013, as consumption of all fossil fuels fell and the contribution from renewables rose.  Half the CO2 savings came from power generation.

Germany’s use of hard coal − sometimes called black coal, which emits much less CO2 than brown coal, as lignite is known − in electricity generation was 7.9% lower than in 2013, and lignite 2.3%.  The share of fossil fuels in the overall energy mix fell from 81.9% in 2013 to 80.8%.

At first sight, that looks like a big success story.  But it comes after several years of rising emissions that have cast doubt on the “Energiewende” − the ambitious German energy transition plan for a simultaneous phase-out of nuclear power and a move to a carbon-free economy.

While all of Germany’s remaining nine nuclear power plants must by law be shut down no later than the end of 2022, there is no such legally-binding phase-out for the coal industry.  So no one can tell how long Germany will go on burning the worst climate change contributors, lignite and hard coal.
