Building the biggest renewable energy community

At Holaluz we're building the biggest renewable energy community you can imagine: a network of energy that's clean, decentralised, decarbonised, local and accessible. We're demonstrating every day, that the Rooftop Revolution is possible, and that we're committed to a planet that's ever more sustainable and green.
And, at Holaluz, when we talk about 100% green energy, we're always referring to renewable energy. For us, green energy is the renewable energy that underpins our commitment to a more sustainable planet.
We want to transform the 10 million rooftops available in Spain into producers of renewable energy, making electricity more economical for everyone. And you're a vital part of this revolution!

Roofs with solar panels

Join the greenest community

There are various companies on the market offering clean energy tariffs. But we focus exclusively on offering 100% renewable energy, also known as green energy. This is the distinction between those that consider it to simply be just another product, and those of us who are concerned with the planet and only use energy from sources of renewable energy.

At Holaluz, we believe in a future in which renewable energy plays a leading role, and we work to make that possible every day. Join our community of people committed to the planet, and together we'll build a better, more sustainable future!

Holaluz: energy transition and renewable energy

Renewable energy, also known as green energy, is energy generated by inexhaustible natural resources. Renewable energies are wind, hydraulic, solar and biomass. These sources of energy offer us an alternative that's respectful of the environment, liberating the planet from its dependency on fossil fuels and their impact on climate change.

At Holaluz, we're taking things to the next level! We're focused on connecting people to renewable energy. But what does that mean? Through the intensive use of data and technology, we're creating a huge virtual power plant that will make it possible to decommission fossil fuel power plants and build the electricity grid of the future:

  • Electricity is produced and consumed in homes with solar panels and batteries.
  • The surplus goes into the local network so that other customers who don't have rooftops can benefit from energy that's green, cheap and local, with no transport or distribution costs.
  • Flexible assets such as batteries for solar panels and electric car chargers allow customers to use green and proximity electricity throughout the day with minimal fixed costs.

With us, if you consume energy from the grid at any time, that energy will also be of 100% renewable origin. We want to make the most of every roof's potential. Yes, yours too! Because our sole focus is on people and the planet.

Where does the renewable energy we buy come from?


Electricity obtained from the use of biomass (agricultural, forestry, etc.) as fuel.


Wind energy

Electricity obtained from the wind, which transforms mechanical energy into electrical energy.


Photovoltaic solar energy

We take advantage of the energy of the sun through photovoltaic solar panels.


Thermoelectric solar energy

Electricity generated from the sun in thermoelectric power plants.


Hydraulic energy

It comes from the water of swamps and reservoirs (when it is released suddenly, it produces electrical energy).


Biomass (waste)

The energy contained in waste (paper, cardboard, organic waste...) as fuel and which is used to generate electricity.

At Holaluz we want to make a difference and contribute to improving our world, which is why adopting sustainable measures is vital.

But we're relying on you! You can choose a company that focuses exclusively on providing green energy and working with sources of renewable energy.
