Top 10: European Renewable Energy Companies
Renewables made up nearly a quarter of Europe’s power generation in 2022 according to the European Environment Agency (EEA).
The EEA says that the energy sector is responsible for around 75% of the continent’s emissions, so the amount of renewable energy needs to continue to rise.
Across Europe, renewable energy companies are taking action to decarbonise energy.
Sustainability Magazine has ranked 10 of the top European renewable energy companies.

RWE has added renewable energy to its portfolio and aims to become climate neutral by 2040.
In July 2025, it energised its Langford Solar Farm, the company’s first solar project in the UK to enter operation.
Katja Wünschel, CEO for RWE Renewables Europe & Australia, said: “The energisation of Langford Solar Farm marks an important step for RWE’s solar ambitions in the UK and is a testament to the dedication, expertise and passion of our team.”
7. ENGIE
CEO: Catherine MacGregot
Headquarters: Paris, France
Founded: 2008
Renewable capacity: 19 GW
ENGIE is one of Europe’s largest utilities and operates electricity and energy supply chains in 48 countries.
The company has deployed an investment plan of up to US$27.8bn by 2028 to reinforce its sustainable energy supply and aims to reduce total greenhouse gas emissions 55% by 2030.
“We aim to become the best utility in the energy transition, with a target of 95 GW of installed renewable and storage capacity by 2030,” says Catherine MacGregor, CEO at ENGIE.
6. Statkraft
CEO: Birgitte Ringstad Vartdal
Headquarters: Oslo, Norway
Founded: 1992
Renewable capacity: 21 GW
With more than a century of experience in hydropower, Statkraft generates a significant amount of renewable energy.
The company has applied to build a project in Norway with a budget of more than US$550m.
Statkraft CEO Birgitte Ringstad Vartdal said: “Electricity is the backbone of our society and the foundation for value creation across the country.
“By building a new Aura power plant, we can deliver more capacity - and slightly more energy - without adding more water.”
5. TotalEnergies
CEO: Patrick Pouyanné
Headquarters: Paris, France
Founded: 1924
Renewable capacity: 28 GW
By 2030, TotalEnergies aims to reach 100 GW of installed renewable capacity with a focus on wind and solar.
In June 2025, the company acquired a pipeline of eight solar and battery projects in the UK as part of its Integrated Power strategy.
Olivier Jouny, SVP renewables at TotalEnergies, said: “The acquisition of these solar and battery projects located in the south of England will complement our integrated electricity portfolio in the UK.”
4. Iberdrola
CEO: Pedro Azagra
Headquarters: Bilbao, Spain
Founded: 1992
Renewable capacity: 45 GW
Iberdrola is the largest producer of wind power in Europe and is investing in other renewable sources like solar and hydroelectric.
In April 2025, the company received planning approval for the Windanker offshore wind farm in the German Baltic Sea, now scheduled to be operational in 2026.
Felipe Montero, CEO of Iberdrola Germany, says: "We are continuing our growth course and clearly demonstrating Iberdrola's commitment to the German renewable energy market."
3. Enel
CEO: Flavio Cattaneo
Headquarters: Rome, Italy

Hybridisation and repowering are two parts of Enel’s strategy to improve the efficiency of renewable energy.
In Venaus, Italy, it has built its first floating solar park as part of a hybrid plant, using double-sided photovoltaic modules to use the natural reflection of water to maximise power generation.
2. Siemens Energy
CEO: Christian Bruch
Headquarters: Munich, Germany
Founded: 2020
Renewable capacity: 117 GW
Siemens Energy was spun off from Siemens in 2020 and later brought Siemens Gamesa with it, the world’s second largest wind turbine manufacturer. A sixth of global energy generation is based on the company’s technology.
These technologies are at the core of many major renewable energy projects, including 1.4 GW offshore wind farm East Anglia THREE and a 1 GW electrolyser in Berlin for green hydrogen production.
Siemens Energy’s roots spread back through Siemens’ founding in 1847.
“Long before April 2020, our engineers were already electrifying cities, industries and entire countries,” said Christian Bruch, CEO at Siemens Energy, on the company’s five-year anniversary.
“At a time when electricity was still a marvel, they were already building the foundations of the energy systems we rely on today. That same drive to energise society has never faded.”
1. Vestas
CEO: Henrik Andersen
Headquarters: Aarhus, Denmark
Founded: 1945
Renewable capacity: 189 GW
Vestas has installed more wind power capacity than any other firm – more than 189 GW, including more than 10 GW offshore.
The company came to be through a blacksmith shop established in 1898 before beginning to produce household appliances in 1945. In 1979 Vestas entered the wind energy sector, dedicating itself exclusively to producing wind turbines from 1989.
It has an international presence in more than 80 countries and produces turbines as tall as 280 metres – taller than all buildings in London except the Shard. The V236-15.0 MW has a rotor diameter of 236 metres.
In May 2025, Vestas signed a deal for a blades factory in Poland to manufacture wind turbine parts for its onshore wind solutions.
Vestas Chief Technology and Operations Officer Anders Nielsen says: “Europe needs secure, affordable and sustainable energy more than ever and we’re pleased to expand our European manufacturing footprint to support wind energy’s growing role in Europe’s energy system.”
