Q1 What is the German Energiewende?
The German Energiewende is a long-term energy and climate strategy that is based on developing renewable energy and improving energy efficiency. It involves a fundamental transformation A of Germany’s power system, including a shift from coal and nuclear to renewable energy. The Energiewende first started decades ago. A broad consensus has emerged on the need for this transformation.
The German Energiewende: a long-term Energiewende is an integrated policy that addresses energy and climate strategy all sectors of the economy. It is driven by four main political objectives: fighting climate change (through The German Energiewende (roughly, “energy transi- a reduction of CO₂ emissions), phasing-out nuclear tion”) is a long-term strategy for the development of power, improving energy security (through a reduc- a low-carbon energy system that is based on renew- tion of fossil-fuel imports) and guaranteeing indus- able energy and improved energy efficiency.

The Energiewende first started decades ago and a broad consensus has emerged on its objectives and necessity
The Energiewende has its roots in public opposition to nuclear power, in the sustainable development movement, and in public support for action on climate change. A program to develop nuclear energy was launched in West Germany in the 1950s, although it faced heavy public opposition from the start. In the 1970s and 80s, a fierce anti-nuclear protest move- ment blocked development at potential reactor sites; several planned nuclear facilities were never realized. The Chernobyl disaster in 1986 was a first turning point in government policy. No new reactors were constructed in Germany after the accident. Then, in 2002, a first law was adopted to phase out nuclear energy by approximately 2022. Eight years later, in 2010, the government decided after a controversial debate to delay the nuclear phase-out until 2036. However, this decision was immediately reversed after the nuclear accident at Fukushima Daiichi in March 2011. In June 2011, the government reinstated the previous nuclear phase-out policy in an historic instance of cross-party support.

Q2 How is Germany progressing with its Energiewende?
Renewable energy has become a key pillar of the power system. In 2016, renewables accounted for about 30 per cent of Germany’s power production. After years of falling costs, wind energy and solar A PV have become the backbone of the German power system transformation. Progress in the area of energy efficiency has been more moderate, as power consumption is only 4 per cent below its 2008 levels.

The LCOE is a metric used to compare the generation costs (EUR/kWh) of diff erent technologies, taking into account fi xed and variable costs, as well as cost of capital (WACC). In general, feed-in tariff s are slightly higher than the LCOE, as energy producers usually include revenue margins in their calculations.

and sustainability concerns. Wind and solar PV have undergone considerable development, primar- ily thanks to the feed-in tariff system introduced by the German Renewable Energy Act (EEG) (see Q10). In recent years the costs of these technologies have dropped dramatically due to technological progress and economies of scale. Cost declines have been par- ticularly dramatic for solar PV, which experienced a 80 per cent decline between 2005 and 2015. Wind energy and solar PV are now competitive with con- ventional energy sources for new investment: in 2016 generation costs in Germany stood at 5–9 cts€/kWh for wind energy and 6–9 cts€/kWh for solar PV (see Figure 2). Moreover, future cost declines are expected.
In 2016, the cumulative installed capacity of those two technologies exceeded 89 GW (onshore wind: 44.8 GW, offshore wind: 4.1 GW, photovoltaics: 40.4 GW), thus comprising approximately 15 per cent of national power consumption. At current growth rates, renewable energy sources will be able to more than compensate for the phase-out of nuclear by 2022.

Q3 Does Germany import nuclear and coal electricity from neighbouring countries to compensate for the nuclear phase-out?
No. Germany has been a net exporter of power to its neighbours since 2003, reaching a new export A record in 2015. Renewable energy sources have more than compensated for the closure of nuclear power plants since Fukushima nuclear accident.
Germany is a net exporter of power tria, France, the Netherlands are the main import- to its neighbours, despite the nuclear ers of power from Germany. Germany is a strong phase-out exporter because it has the second-lowest power prices in Europe after Scandinavia. These low prices Germany has been a net exporter of electricity since are attributable to the rapid expansion of renewable 2003.
