Germany's renewable energy sector is among the most innovative and successful worldwide. Nordex, Repower, Fuhrländer and Enercon are wind power companies based in Germany. Solon SE, Q-Cells and Conergy are solar power companies based in Germany. These companies dominate the world market. Every third solar panel and every second wind rotor is made in Germany, and German turbines and generators used in hydro energy generation are among the most popular worldwide.[1] In 2010, investments totaling 26 billion euros were made in Germany’s renewable energies sector. According to official figures, some 370,000 people in Germany were employed in the renewable energy sector in 2010, especially in small and medium sized companies. This is an increase of around 8 percent compared to 2009 (around 339,500 jobs), and well over twice the number of jobs in 2004 (160,500). About two-thirds of these jobs are attributed to the Renewable Energy Sources Act[2][3] Germany has been called "the world's first major renewable energy economy".[4]

The share of electricity produced from renewable energy in Germany has increased from 6.3 percent of the national total in 2000 to about 25 percent in the first half of 2012.[5][6] In 2011 20.5% (123.5 TWh) of Germany's electricity supply (603 TWH) was produced from renewable energy sources, more than the 2010 contribution of gas-fired power plants.[7][8] Siemens chief executive, Peter Löscher believes that Germany’s target of generating 35 per cent of its electricity from renewables by 2020 is achievable – and, most probably, profitable for Europe’s largest engineering company.

In 2012, the use of variable renewable energy is, according to the German newspaper Der Spiegel, causing increasing electricity prices and grid instability induced power outages.[9] However, based on official statistics for the period between 2007 and 2012, electricity prices for industrial consumers in Germany were decreased from €94.6 to €89.5 per MWh.[10]

Renewable energy targets [edit]

Wind and solar power accounted for over 16% of the electricity generated in Germany in 2012

Since the passage of the Directive on Electricity Production from Renewable Energy Sources in 1997, Germany and the other states of the European Union have been working towards a target of 12% renewable electricity by 2010. Germany passed this target early in 2007 when the renewable energy share in electricity consumption in Germany reached 14%.[11] In September 2010 the German government announced the following new ambitious energy targets:[12]

  • Renewable electricity - 35% by 2020, 50% by 2030, 65% by 2040, and 80% by 2050
  • Renewable energy - 18% by 2020, 30% by 2030, and 60% by 2050
  • Energy efficiency - Cutting the total energy consumption by 20% from 2008 by 2020 and 50% less by 2050
  • Total electricity consumption - 10% below 2008 level by 2020 and 25% less by 2050

The German Government reports that in 2011 renewable energy (mainly wind turbines and biomass plants) generated more than 123 TWh (billion kilowatt-hours) of electricity, providing nearly 20% of the 603 TWh of electricity supplied.[7]

Chancellor Angela Merkel, along with a vast majority of her compatriots, believes that, "As the first big industrialized nation, we can achieve such a transformation toward efficient and renewable energies, with all the opportunities that brings for exports, developing new technologies and jobs".[13]

Wind power [edit]

See main article: Wind power in Germany

Wind power in Germany describes wind power in Germany as part of energy in Germany and renewable energy in Germany. In 2011, the installed capacity of wind power in Germany was 29,075 megawatts (MW), with wind power producing about 8 percent of Germany’s total electrical power.[14] According to EWEA in a normal wind year, installed wind capacity in Germany will meet 10.6% at end 2011 and 9.3% at end 2010 of the German electricity needs.[15][16]

More than 21,607 wind turbines are located in the German federal area and the country has plans to build more wind turbines.[17][18] As of 2011, Germany's federal government is working on a new plan for increasing renewable energy commercialization,[19] with a particular focus on offshore wind farms.[20] A major challenge is the development of sufficient network capacities for transmitting the power generated in the North Sea to the large industrial consumers in southern Germany.[21]

Photovoltaic solar power [edit]

Solar Electricity potential in Germany

In July 2012, there was a cumulative installed total solar PV power of 29.7 GW.[22] Solar PV provided 18 TW·h (billion kilowatt-hours) in 2011, 3% of the total electricity demand. As solar power installations rise fastly, in first half of 2012, about 5.3% of the total electricity demand was covered by solar power.[23] At 25 May 2012, a Saturday, solar power reached a new record with feeding 22 GW, as much as 20 nuclear power stations, into the German power grid, which made 50% of the nation's midday's electricity demand.[24]

Some market analysts expect the solar electricity share could reach 25 percent by 2050.[25] Price of PV systems has decreased more than 50% in 5 years since 2006.[26]

Geothermal power [edit]

See main article: Geothermal power in Germany

The installed capacity for geothermal energy in Germany was of 8.9 MW in 2007.[27]

Hydroelectricity [edit]

The total installed capacity in Germany at the end of 2006 was 4.7 GW. Hydropower meets 3.5% of the electricity demand. Latest estimates show that in Germany in 2007 approx. 9,400 people were employed in the hydropower sector which generated a total turnover of €1.23 billion.[28]

Biofuels [edit]

Biofuel and biomass is one of Germany's most important sources of renewable energy. In 2010, biomass accounted for 30% of renewable electricity generation[29] and for 70% of all renewable energy (mostly wood).[30]

Germany has committed to blending 6.25% biofuels in petroleum by 2014 with the Biofuels Quota Act.[31][32]

Renewable energy industry [edit]

Germany's renewable energy sector is among the most innovative and successful worldwide. Nordex, Repower, Fuhrländer and Enercon are wind power companies based in Germany. SolarWorld, Q-Cells and Conergy are solar power companies based in Germany. These companies dominate the world market. Every third solar panel and every second wind rotor is made in Germany, and German turbines and generators used in hydro energy generation are among the most popular worldwide.[1]

Nearly 800,000 people work in the German environment technology sector; an estimated 214,000 people work with renewables in Germany, up from 157,000 in 2004, an increase of 36 percent.[1]

Siemens chief executive, Peter Löscher believes that Germany’s target of generating 35 per cent of its energy from renewables by 2020 is achievable – and, most probably, profitable for Europe’s largest engineering company. Its “environmental solutions” portfolio, which is firmly focused on renewables, is “already generating more than €27 billion a year, 35 per cent of Siemens’ total revenue, and the plan is to grow this to €40 billion by 2015”. Ending its involvement in nuclear industry will boost the credibility of Siemens as a purveyor of “green technology”.[33]

Germany's main competitors in solar electricity are Japan, the US and China. In the wind industry it is Denmark, Spain and the US.

Government policy [edit]

The renewable energy sector benefited when the Alliance '90/The Greens party joined the Federal Government between 1998 and 2005. The renewable energy sector was aided especially by the Renewable Energy Sources Act that promotes renewable energy mainly by stipulating feed-in tariffs that grid operators must pay for renewable energy fed into the power grid. People who produce renewable energy can sell their 'product' at fixed prices for a period of 20 or 15 years. This has created a surge in the production of renewable energy.[34] In 2012, Siemens estimated the total cost of renewable energy would come to at least €1.4 trillion (US$1.8 trillion) by 2030.[35]

For the 2005–2010 period the Federal Government set aside nearly 800 million euros for scientific research in the country. That research will be earmarked for policies of long-term development. Additionally, in 2001 a law was passed requiring the closing of all nuclear power plants within a period of 32 years. The shutdown time was extended to 2040 by a new government in 2010. After the Fukushima incident, the law was abrogated and the end of nuclear energy was set to 2022.

The cost of replacing Germany's nuclear power generation with renewable energy has been officially estimated by the German Ministry of Economics at about €0.01/(kW·h) (about €55 billion for the next decade), on top of the €13 billion per year already devoted to subsidizing renewables. However, unofficial estimates of the ministry, and of the Rhenish-Westphalian Institute for Economic Research (RWI), German Energy Agency (DENA), Federation of German Consumer Organizations (VZBV), and the government-owned development bank (KfW), put the cost several times higher, at about €250 billion ($340 B) over the next decade.[36][37]

The German energy policy is framed within the European Union, and the March 2007 European Council in Brussels approved a mandatory energy plan that requires a 20% reduction of carbon dioxide emissions before the year 2020 and the consumption of renewable energies to be 20% of total EU consumption (compared to 7% in 2006).[38] The accord indirectly acknowledged the role of nuclear energy — which is not commonly regarded as renewable, but emissions-free — in the reduction of the emission of greenhouse gasses, allowing each member state to decide whether or not to use nuclear generated electricity.[39]

Also a compromise was reached to achieve a minimum quota of 10% Biofuels in the total consumption of gasoline and diesel in transport in 2020.

Debate [edit]

A 2009 study from RWI Essen of the effects of the Renewable Energy Sources Act concluded that:

  • using photovoltaics in emission reduction is 53 times more expensive than the European Union Emission Trading Scheme's market price, while wind power is 4 times more expensive, thereby discouraging other industries from finding more cost-effective methods of reducing emissions;
  • although renewable energy subsidies increase retail electricity rates by 3%, they reduce the profits of German electrical utilities by an average of 8%, making them less competitive with other European utilities;
  • despite lavish subsidies, Germany's photovoltaic industry is losing its market share to other countries, particularly China and Japan;
  • it stifles renewable energy innovation by arbitrarily awarding subsidies to different technologies, instead of according to their cost-effectiveness.[40]

Germany's Federal Ministry for Environment, Nature Conservation and Nuclear Safety responded to the RWI Essen study, describing the criticisms as "well known and refuted a long time ago".[41]

In 2013, Peter Altmaier, an environment minister in Germany stated.[42]

The costs of our energy reform and restructuring of energy provision could amount to around 1 trillion euros by the end of the 2030s...We need a cost brake that will limit the costs of renewable energy equally for all consumers for the long term.

Germany was generating about 25 percent of its electricity from coal, about 61 percent from fossil fuels in total, 23 percent from nuclear power and about 15-20 percent from renewable sources in 2009. In 2012 The German electricity sector increased its coal usage by 4.9 percent over its coal consumption value of 2011.[43] This increase in coal usage was largely due to a power gap in Germany created after the nation shutdown 8 of its 17 nuclear power plants.[44] The shortfall in electricity supply from these 8 power plants, is primarily being filled by building more lignite coal burning power plants.[45][46] The return to coal in Germany, beginning in 2011, could undermine the nations legal commitment to the kyoto protocol's carbon dioxide reductions.[47][48][49]

In 2012, the use of variable renewable energy is, according to the German newspaper Der Spiegel, causing increasing electricity prices and grid instability induced power outages.[50][51] Based on official statistics for the period between 2007 and 2012, electricity prices for industrial consumers in Germany decreased from €94.6 to €89.5 per MWh.[52] Based on the same statistics for the period between 2006 and 2012, electricity prices for industrial consumers in Germany increased from €87.1 to €89.5 per MWh in 2012.[53] Moreover, according to a 2012 survey conducted by members of the Association of German Industrial Energy Companies in relation to power outages:[54]

The number of short interruptions to the German electricity grid has grown by 29 percent in the past three years. Over the same time period, the number of service failures has grown 31 percent, and almost half of those failures have led to production stoppages.[Machinery] Damages have ranged between €10,000 and hundreds of thousands of euros, according to company information.
