Iberdrola, world leader in renewable energy

We began our commitment to renewable energy more than two decades ago as the foundation on which to build its clean, reliable and smart business model.

The Iberdrola Group is today a world leader in renewable energy sources, with 42,387 MW of operational renewables by the end of the first quarter of 2024, and on the cutting edge of the energy transition towards a low-emissions economy. This commitment is reflected in our Strategic Plan 2024-2026, in which we plan to allocate €15.5bn to renewable business to grow selectively in flexible technologies and storage. More than half of this amount is focused on offshore wind in the United States, the United Kingdom, France and German; 28% on onshore wind and 18% on solar..


Benchmarks in renewables with new, landmark projects

The Iberdrola Group has opened new platforms for growth to position itself in markets with massive potential for renewables and has strengthened its presence in the main countries where it operates.

It is currently building several projects which have become real milestones because of their size and innovative nature. Renewable energy sources is a major part of these projects and Iberdrola currently has 17 of these plants in construction or development.

Leaders in wind generation, also in the sea

One of the Group's main growth vectors is offshore wind. The company currently has 1.819 GW installed. Furthermore, according to the company's strategy in the offshore wind energy sector, which is reflected in our Strategic Plan, from 2027 we will have 3,000 new MW of operational capacity, reaching 5,000 MW offshore.

Pioneers in green hydrogen development

The decarbonisation of the planet is among the objectives that countries around the world have set for 2050. To achieve this, the decarbonisation of hydrogen —which currently accounts for more than 2 % of the world's total CO2 emissions— by producing green hydrogen, will be a major step forward. This technology is based on generating hydrogen  —a universal, light and highly reactive fuel— by means of a chemical process known as electrolysis.

What are renewable energies

Renewable energy is generated using natural sources that will never run out,  because they contain a massive quantity of energy —such as the sun or the wind— or because they are able to regenerate fast, like biomass.

To meet growing global demand for energy and the imperative need to halt climate change, renewables are now established as the best option for the future of the energy sector. Let us tell you all about this type of energy.

The main renewable energy technologies are offshore and onshore wind, hydroelectric power, photovoltaics, green hydrogen and hybrid hydrogen.

What are the advantages of renewable energy?

Renewable energy has many advantages over non-renewable energy.

Icon They respect the environment

Most do not produce greenhouse gases or other pollutant emissions

Icon They are unlimited

They are drawn from nature’s inexhaustible resources and can be drawn upon permanently

Icon They are safer for our health

They do not emit gases harmful to living beings


Icon They offer greater flexibility

They can be installed anywhere: boats, motorhomes, homes, buildings, etc.

Icon They do not generate waste that is difficult to treat

They are easy to dismantle and do not neeed to be stored

Icon They promote employment

They create five times more jobs than conventional energy

Icon They promote energy independence

They develop the region’s economy, promoting its autonomy

Differences between renewable and non-renewable energy

The main difference between renewable and non-renewable energy sources is that the former can produce energy indefinitely because these sources will never run out or renew themselves within a short period of time, while non-renewable energy reserves are limited because they run out when used or regenerate extremely slowly.

Another difference is that renewable energy is highly sustainable and has a very low environmental footprint, unlike non-renewables.

What are clean energy sources?

Clean energy consists of energy production systems that do not produce any pollution, notably greenhouse gases like CO2.

Therefore, clean energies are driving our progress in protecting the environment and alleviating the crisis caused by non-renewable sources, such as gas and oil.
