Energy policy: general principles

EU energy policy is based on the principles of decarbonisation, competitiveness, security of supply and sustainability. Its objectives include ensuring the functioning of the energy market and a secure energy supply within the EU, as well as promoting energy efficiency and savings, the development of renewable energies and the interconnection of energy networks. A variety of measures aiming to achieve a complete Energy Union is at the core of the EU’s energy policy.

Legal basis

Article 194 of the Treaty on the Functioning of the European Union (TFEU).

Specific provisions:

  • Security of supply: Article 122 TFEU;
  • Energy networks: Articles 170-172 TFEU;
  • Coal: Protocol 37 clarifies the financial consequences resulting from the expiry of the Treaty establishing the European Coal and Steel Community in 2002;
  • Nuclear energy: the Treaty establishing the European Atomic Energy Community (Euratom Treaty) serves as the legal basis for most EU actions in the field of nuclear energy.

Other provisions affecting energy policy:

  • Internal energy market: Article 114 TFEU;
  • External energy policy: Articles 216-218 TFEU.


According to the Energy Union (2015), the five main aims of the EU’s energy policy are to:

  • Diversify Europe’s sources of energy, ensuring energy security through solidarity and cooperation between EU countries;
  • Ensure the functioning of a fully integrated internal energy market, enabling the free flow of energy through the EU through adequate infrastructure and without technical or regulatory barriers;
  • Improve energy efficiency and reduce dependence on energy imports, cut emissions, and drive jobs and growth;
  • Decarbonise the economy and move towards a low-carbon economy in line with the Paris Agreement;
  • Promote research in low-carbon and clean energy technologies, and prioritise research and innovation to drive the energy transition and improve competitiveness.

Article 194 TFEU makes some areas of energy policy a shared competence, in which each Member State maintains its right to ‘determine the conditions for exploiting its energy resources, its choice between different energy sources and the general structure of its energy supply’ (Article 194(2)).


A. General policy framework

The current European energy policy is based on the Energy Union strategy, which aimed to give EU households and businesses a secure, sustainable, competitive and affordable energy supply. The current EU energy targets for 2030 include:

  • An increase in the share of renewable energies in final energy consumption to 42.5%, with the aim of achieving 45%;
  • An 11.7% reduction in primary (indicative) and final energy consumption, compared to 2020 projections;
  • The interconnection of at least 15% of the EU’s electricity systems.

The current European regulatory framework for energy was built on the EU’s substantial ‘Fit For 55’ package, which was initially aimed at aligning all climate and energy targets. This was successively modified by the REPowerEU plan, whose aim was to rapidly and completely phase out dependency on Russian fossil fuels.

The framework is composed of several provisions covering the promotion of renewable energy (Directive (EU) 2018/2001), energy efficiency (Directive (EU) 2018/2002), governance and electricity interconnectivity (Regulation (EU) 2018/1999), electricity market design (Directive (EU) 2019/944 and Regulation (EU) 2019/943), risk-preparedness (Regulation (EU) 2019/941), the energy performance of buildings (Directive (EU) 2018/844), decarbonised gas and hydrogen markets (Directive 2009/73/EC and Regulation (EC) No 715/2009), energy taxation (Directive 2003/96/EC), trans-European energy infrastructures (Regulation (EU) 2022/869), cooperation of energy regulators (Regulation (EU) 2019/942), batteries (Regulation (EU) 2023/1542), and air and maritime transport initiatives (Regulation (EU) 2023/2405 and Regulation (EU) 2023/1805). Under the current framework, EU countries need to establish 10-year integrated national energy and climate plans for the period from 2021 to 2030, submit a progress report every two years and develop consistent national long-term strategies to meet the agreed energy targets and the goals of the Paris Agreement.

B. Completing the internal energy market

A fully integrated and properly functioning internal energy market ensures affordable energy prices, gives the necessary price signals for investments in green energy, secures energy supplies and opens up the least costly path to climate neutrality. The internal energy market legislation was initially based on the principles of cross-border cooperation and fair retail markets. The legislation later focused on risk-preparedness, coordination, incentives for consumers, decarbonisation and security of energy supply.

As a result of the REPowerEU modifications, the energy framework was extended to include rules for minimum gas storage filling levels of 90% ahead of winter (Regulation (EU) 2022/1032), voluntary gas demand reduction targets for EU countries of 15% (Regulation (EU) 2022/1369; the period for voluntary demand reduction was extended to March 2025), voluntary demand aggregation of gas (Regulation (EU) 2022/2576; EU Energy Platform), electricity demand reduction targets of 10% and 5% during peak hours and time-limited emergency interventions to address high energy prices (Regulation (EU) 2022/1854) (see fact sheet 2.1.9 on the internal energy market).

C. Energy Efficiency

The cornerstone of the EU’s energy efficiency policy is the new Energy Efficiency Directive (Directive (EU) 2023/1791), which established an 11.7% target for the reduction of the primary (indicative) and final energy consumption of the EU by 2030, compared to 2020 projections. This is equivalent to no more than 992.5 (indicative) and 763 million tonnes of oil equivalent respectively. The directive is based on the ‘energy efficiency first’ principle, which sets an obligation for EU countries to ensure that energy efficiency solutions are considered in planning, policy and investment decisions (see fact sheet 2.4.8 on energy efficiency).

D. Renewable Energy

The cornerstone of EU renewable energy policy is the new Renewable Energy Directive, which established a 42.5% target for the share of renewable energies (solar power, wind, ocean and hydropower, biomass and biofuels) in the final energy consumption of the EU by 2030, with the aim of achieving 45%. The directive promotes renewable energies with national support and EU financing schemes as energy markets alone cannot deliver the desired level of renewables in the EU (see fact sheet 2.4.9 on renewable energy).

E. Strengthening external energy relations

Following the decision to phase out Russian energy imports, the current EU external energy policy is driven by the diversification of its energy supply. In March 2022, the REPowerEU communication proposed massive and fast reductions in EU fossil gas use of at least 155 billion cubic metres, equivalent to the volume imported from Russia in 2021. In line with the REPowerEU plan, the EU worked with international partners to diversify supplies, secure liquefied natural gas imports and increase new pipeline gas deliveries. It created the EU Energy Platform, a voluntary coordination mechanism supporting the joint EU purchase of gas and hydrogen, and published the EU External Energy Strategy supporting Ukraine, Moldova and other countries.

F. Improving security of energy supply

After the Russian invasion of Ukraine, security of energy supply became the main energy priority of the EU. The current energy security policy includes coordination measures and rules to prevent and respond to accidents on offshore installations and disruptions to energy supply and emergency oil and gas stocks, including exploration and production licences.

The EU’s trans-European infrastructure policy is covered by the Trans-European Networks (TENs) regulations (see fact sheet 3.5.1 on TENs). Adopted in June 2022, the TEN-E regulation on trans-European energy infrastructure identifies 11 priority corridors in different geographic regions for electricity, offshore grid and hydrogen infrastructure. It defines EU projects of common interest within EU countries and projects of mutual interest between the EU and non-EU countries, ends support for new natural gas and oil projects and introduces mandatory sustainability criteria for all projects. TENs policies are funded by the Connecting Europe Facility 2021-2027, established by Regulation (EU) 2021/1153 (see fact sheet 3.5.2 on financing TENs).

G. Research, development and demonstration projects

Horizon Europe is the framework programme running from 2021 to 2027 and the main EU tool for promoting energy research, with a budget of EUR 95.5 billion (in 2018 prices), including EUR 5.4 billion from the NextGenerationEU programme (see fact sheet 2.4.6 on research policy)

The European strategic energy technology plan identified 10 technologies (including batteries, photovoltaics, offshore wind, etc.) and actions for research and innovation, covering the whole green energy innovation chain.

Role of the European Parliament

Parliament has always expressed its strong support for a common energy policy addressing decarbonisation, competitiveness, security and sustainability issues. It has called numerous times for coherence, determination, cooperation and solidarity between EU countries in facing current and future challenges in the internal market and for the political commitment of all Member States.

Parliament’s latest resolutions on energy have seen an increase in the relevance and ambition of all climate and environmental objectives underpinning EU energy policy. In November 2019, Parliament declared the climate and environmental emergency in Europe. In October 2020, in a series of amendments to the proposal for a regulation establishing the framework for achieving climate neutrality, it called for an EU reduction target of 60% for all greenhouse gas emissions by 2030 and for a phase-out of all fossil fuel subsidies by 2025 at the latest. As a reaction to the COVID-19 pandemic, it reaffirmed the green and digital strategies as the cornerstones of the EU Energy Union. In September 2022, it supported more ambitious energy efficiency and renewable energy targets.

On 1 March 2022, Parliament published a resolution on the Russian aggression against Ukraine, which condemned Russia’s illegal, unprovoked and unjustified military invasion of Ukraine. In April 2022, Parliament called for an immediate full embargo on Russian imports of oil, coal, nuclear fuel and gas. In October 2022, in its resolution on the EU’s response to the increase in energy prices in Europe, Parliament called on EU countries to avoid evictions of vulnerable households and the cutting off of their energy supplies, and expressed regret that the Commission tabled many of its proposals in the form of a Council regulation instead of using a co-decision procedure. It also adopted several other resolutions on specific aspects of the conflict: welcoming the granting of EU candidate status to Ukraine and Moldova and a European perspective for Georgia; enhancing the EU’s protection of children and young people fleeing the war in Ukraine; and highlighting the impact of the war on women.

Parliament supports the diversification of energy sources and routes of supply. It has stressed the importance of the gas and electricity interconnections through central and south-eastern Europe along a north-south axis for creating more interconnections, diversifying liquefied natural gas terminals and developing pipelines. In highlighting the significant role of research in ensuring a sustainable energy supply, Parliament stressed the need for common efforts in the field of new energy technologies, as well as for additional public and private funding.
