Energía renovable en España: dónde estamos hoy y por qué gestionar bien tu consumo
Renewable energy has been gaining ground in Spain for years, and it is no coincidence. They are clean, virtually inexhaustible sources and increasingly competitive in price, which makes them a key piece both for reducing energy dependence and for moving towards a productive model with fewer emissions.
The most recent data confirms this trend. According to the renewable energy report by Red Eléctrica, in 2025 renewable energy reached 55.5% of electricity generation in Spain, a figure that rises to 56.6% if the estimate for self-consumption is added. Wind was the leading technology in the mix, followed closely by photovoltaics, and in terms of installed power, renewables already represent close to 69% of the Spanish generation fleet (70.5% counting self-consumption). These are the best historical records of the Spanish electricity system to date.
This growth is not just good environmental news. The greater the weight of renewables in the mix, the lower the wholesale price of electricity tends to be, since it is the only source that, when its production increases, pulls the price down instead of making it more expensive. For any company with significant electricity consumption, this translates into a real opportunity to reduce costs while making progress in sustainability.
Public administrations have been joining this movement for some time. More and more Spanish municipalities are contracting their electricity supply with retailers certified by the National Markets and Competition Commission (CNMC), which guarantees that the energy supplied comes 100% from renewable sources. This commitment is usually accompanied by other mobility and urban efficiency measures, such as the promotion of electric public transport in several Spanish cities.
The private sector is not lagging behind either. Major international companies have been committed for years to covering a large part of their consumption with renewable energy, and this momentum has spread to companies in very different sectors. In Spain, for example, hotel chains like NH have committed to energy management certifications such as ISO 50001 as part of their sustainability strategy.
On a global level, the challenge remains enormous: there are still hundreds of millions of people without access to electricity, and guaranteeing this access without skyrocketing emissions requires accelerating both renewable production and consumption efficiency. Years ago, countries like Portugal or Costa Rica demonstrated that it was possible to sustain their electricity demand solely with renewable sources for entire days, milestones that at the time served as a reference for the rest of the world and are today much more common thanks to technological progress.
Smarkia has been part of this journey for a long time, participating, for example, in European urban energy efficiency projects such as Remourban, contributing its management and measurement platform for cities like Valladolid.
More renewables in the mix is great news, but it only translates into real savings if energy is managed well. Monitoring consumption, detecting deviations, and acting on them in real time is what allows a company to truly take advantage of this transition, instead of simply watching it from the outside.
