Energy transition is generally defined as a long-term structural change in energy systems.[1] These have occurred in the past, and still occur worldwide. Historic energy transitions are most broadly described by Vaclav Smil.[2] Contemporary energy transitions differ in terms of motivation and objectives, drivers and governance.

An example of transition toward sustainable energy, is the shift by Germany (German: Energiewende), to decentralised renewable energy, and energy efficiency. Although so far these shifts have been replacing nuclear energy, their declared goal is the abolishment of coal, reducing non-renewable energy sources[3] and the creation of an energy system based on 60% renewable energy by 2050.[4]

Renewable energy encompasses wind, hydropower, solar power, geothermal, and ocean power. These renewable sources are to serve as an alternative to fossil fuels (oil, coal, natural gas) and nuclear fuel (uranium). Solving the energy/global warming problem is regarded as the most important challenge facing humankind in the 21st century.[5]

Piecemeal measures often have only limited potential, so a timely implementation for the energy transition requires multiple approaches in parallel. Energy conservation and improvements in energy efficiency thus play a major role. An example of an effective energy efficiency measure is improved insulation for buildings. Smart electric meters can schedule energy consumption for times when electricity is available inexpensively.

After such a transitional period, with a continuing increase in renewable energy production these are expected to make up most, if not all, of the world's energy production in 50 years according to a 2011 projection by the International Energy Agency, dramatically reducing the emissions of greenhouse gases.[6]

The term 'energy transition'[edit]

The term 'energy transition' designates a significant change in energy policy: The term encompasses a reorientation of policy from demand to supply and a shift from centralized to distributed generation (for example, producing heat and power in very small cogeneration units), which should replace overproduction and avoidable energy consumption with energy-saving measures and increased efficiency.

In a broader sense the energy transition also entails a democratization of energy:[7] In the traditional energy industry, a few large companies with large centralized power stations dominate the market as an oligopoly and consequently amass a worrisome level of both economic and political power. Renewable energies, in contrast, can as a rule be established in a decentralized manner. Public wind farms and solar parks can involve many citizens directly in energy production.[8] Photovoltaic systems can even be set up by individuals. Municipal utilities can also benefit citizens financially, while the conventional energy industry profits a relatively small number of shareholders. Also significant, the decentralized structure of renewable energies enables creation of value locally and minimizes capital outflows from a region. Renewable energy sources therefore play an increasingly important role in municipal energy policy, and local governments often promote them. There is lots of room for growth with wind, solar, geothermal, and biomass for power, they represented 2% of global final energy consumption in 2012.[9]

The speed at which a transition in the energy sector needs to take place will be historically rapid.[10] Moreover, the underlying technological, political and economic structures will need to change radically — a process one author calls regime shift.[11]

Status in specific countries[edit]


Austria embarked on its energy transition (Energiewende) some decades ago. Due to geographical conditions, energy production in Austria relies heavily on renewable energies, notably hydropower. 78.4% of domestic production in 2013 came from renewable energy, 9.2% from natural gas and 7.2% from petroleum. (rest: waste). On the basis of the Federal Constitutional Law for a Nuclear-Free Austria, no nuclear power stations are in operation in Austria. But domestic energy production makes up only 36% of Austria's total energy consumption, which among other things encompasses transport, electricity production, and heating. In 2013, oil accounts for about 36.2% of total energy consumption, renewable energies 29.8%, gas 20.6%, and coal 9.7%. In the past 20 years, the structure of gross domestic energy consumption has shifted from coal and oil to new renewables, in particular between 2005 and 2013 (plus 60%). The EU target for Austria require a renewables share of 34% by 2020 (gross final energy consumption). Austria is on a good way to achieve this target (32.5% in 2013). Energy transition in Austria can be also seen on the local level, in some villages, towns and regions. For example, the town of Güssing in the state of Burgenland is a pioneer in independent and sustainable energy production. Since 2005, Güssing has already produced significantly more heating (58 gigawatt hours) and electricity (14 GWh) from renewable resources than the city itself needs.[12]


Denmark, as a country reliant on imported oil, was impacted particularly hard by the 1973 oil crisis. This roused public discussions on building nuclear power stations to diversify energy supply. A strong anti-nuclear movement developed, which fiercely criticized nuclear power plans taken up by the government,[13] and this ultimately led to a 1985 resolution not to build any nuclear power stations in Denmark.[14] The country instead opted for renewable energy, focusing primarily on wind power. Wind turbines for power generation already had a long history in Denmark, as far back as the late 1800s. As early as 1974 a panel of experts declared "that it should be possible to satisfy 10% of Danish electricity demand with wind power, without causing special technical problems for the public grid."[15] Denmark undertook the development of large wind power stations — though at first with little success (like with the Growian project in Germany).

Small facilities prevailed instead, often sold to private owners such as farms. Government policies promoted their construction; at the same time, positive geographical factors favored their spread, such as good wind power density and Denmark's decentralized patterns of settlement. A lack of administrative obstacles also played a role. Small and robust systems came on line, at first in the power range of only 50-60 kilowatts — using 1940s technology and sometimes hand-crafted by very small businesses. In the late seventies and the eighties a brisk export trade to the United States developed, where wind energy also experienced an early boom. In 1986 Denmark already had about 1200 wind power turbines,[16] though they still accounted for just barely 1% of Denmark's electricity.[17] This share increased significantly over time. In 2011, renewable energies covered 41% of electricity consumption, and wind power facilities alone accounted for 28%.[18] The government aims to increase wind energy's share of power generation to 50% by 2020, while at the same time reducing carbon dioxide emissions by 40%.[19] On 22 March 2012, the Danish Ministry of Climate, Energy and Building published a four-page paper titled "DK Energy Agreement," outlining long-term principles for Danish energy policy.[20]

The installation of oil and gas heating is banned in newly constructed buildings from the start of 2013; beginning in 2016 this will also apply to existing buildings. At the same time an assistance program for heater replacement was launched. Denmark's goal is to reduce the use of fossil fuels 33% by 2020. The country is scheduled to attain complete independence from petroleum and natural gas by 2050.[21]


Since 2012, political discussions have been developing in France about the energy transition and how the French economy might profit from it.[22]

In September 2012, Minister of the Environment Delphine Batho coined the term "ecological patriotism." The government began a work plan to consider starting the energy transition in France. This plan should address the following questions by June 2013:[23]

  • How can France move towards energy efficiency and energy conservation? Reflections on altered lifestyles, changes in production, consumption, and transport.
  • How to achieve the energy mix targeted for 2025? France's climate protection targets call for reducing greenhouse gas emissions 40% by 2030, and 60% by 2040.
  • Which renewable energies should France rely on? How should the use of wind and solar energy can be promoted?
  • What costs and funding models will likely be required for alternative energy consulting and investment support? And how about for research, renovation, and expansion of district heating, biomass, and geothermal energy? One solution could be a continuation of the CSPE, a tax that is charged on electricity bills.

The Environmental Conference on Sustainable Development on 14 and 15 September 2012 treated the issue of the environmental and energy transition as its main theme.[24]

On 8 July 2013, the national debate leaders submits some proposals to the government. Among them, there were environmental taxation, and smart grid development.[25]

In 2015, the National Assembly has adopted legislation for the transition to low emission vehicles.[26]

France is second only to Denmark as having the worlds lowest carbon emissions in relation to gross domestic product.[27]


Market share of Germany's power generation 2014[28]

The key policy document outlining the Energiewende was published by the German government in September 2010, some six months before the Fukushima nuclear accident.[29] Legislative support was passed in September 2010. Important aspects include:

Key Energiewende policy targets (with actual figures for 2014)[30]:4
Target 2014 2020 2030 2040 2050
Greenhouse gas emissions
Greenhouse gas emissions (base year 1990) −27.0% −40% −55% −70% −80 to −95%
Renewable energy
Share of gross final energy consumption 13.5% 18% 30% 45% 60%
Share of gross electricity consumption 27.4% 35% 50% 65% 80%
Efficiency and consumption
Primary energy consumption (base year 2008) −8.7% −20% −50%
Gross electricity consumption (base year 2008) −4.6% −10% −25%
Final energy consumption in transport (base year 2005) 1.7% −10% −40%

In addition, there will be an associated research and development drive.

The policy has been embraced by the German federal government and has resulted in a huge expansion of renewables, particularly wind power. Germanys share of renewables has increased from around 5% in 1999 to 17% in 2010, reaching close to the OECD average of 18% usage of renewables.[31] Producers have been guaranteed a fixed feed-in tariff for 20 years, guaranteeing a fixed income. Energy co-operatives have been created, and efforts were made to decentralize control and profits. The large energy companies have a disproportionately small share of the renewables market. Nuclear power stations were closed, and the existing nine stations will close earlier than necessary, in 2022.

The reduction of reliance on nuclear stations has had the consequence of increased reliance on fossil fuels. One factor that has inhibited efficient employment of new renewable energy has been the lack of an accompanying investment in power infrastructure to bring the power to market. It is believed 8300 km of power lines must be built or upgraded.[31]

Different Länder have varying attitudes to the construction of new power lines. Industry has had their rates frozen and so the increased costs of the Energiewende have been passed on to consumers, who have had rising electricity bills. Germans in 2013 had some of the highest electricity costs in Europe.[32] Nonetheless, for the first time in more than ten years, electricity prices for household customers fell at the beginning of 2015.[30]


On 14 September 2012 the Japanese government decided at a ministerial meeting in Tokyo to phase out nuclear power by the 2030s, or 2040 at the very latest. The government said that it would take "all possible measures" to achieve this goal.[33] A few days later the government retrenched the planned nuclear phaseout after the industry pushed for reconsideration. Arguments cited were that a nuclear phaseout would burden the economy, and that imports of oil, coal, and gas would bring high added costs. The government then approved the energy transition, but left open the time-frame for decommissioning the nuclear power stations.[34]


United Kingdom[edit]

The United Kingdom is mainly focusing on wind power, both onshore and offshore, and in particular is strongly promoting the establishment of offshore wind power. With an installed capacity of 2.1 GW (about half of the world's installed offshore wind power), Britain is the worldwide leader. At the end of 2012, the country had an 8.4 GW of overall installed wind power capacity, putting it in fourth place worldwide, after China, the United States, and Germany. It was initially promoted with a quota system, but expansion targets were missed repeatedly. This led the government to implement a feed-in tariff instead.[35]

United States[edit]

The Obama administration made a large push for green jobs, particularly in his first term.[36]

In the United States, the share of renewable energy (excluding hydropower) in electricity generation has grown from 3.3 percent (1990) to 5.5 percent (2013).[37]

In December 2016, Block Island Wind Farm became the first commercial US offshore wind farm. It consists of five 6 MW turbines (together 30 MW) located near-shore (3.8 miles (6.1 km) from Block Island, Rhode Island) in the Atlantic Ocean. At the same time, Norway-based oil major Statoil laid down nearly $ 42.5 million on a bid to lease a large offshore area off the coast of New York.[38]
