100% Green energy

It's important to see the differences between electrons, and we here at Holaluz see it. We recognize that the origin, the source of these electrons makes a big different in helping us achieve one of our objectives: to change and improve the world. #laluzverde respects the environment and helps to build a better future.

What is green energy?

Green energy, or energy from a renewable source, is what is produced through the natural resources which are unlimited! Renewable energies include wind energy, hydraulic energy, solar energy and biomass.

For us, green energy isn't an option, it's the solution. We can't conceive of a world which isn't heading toward sustainability and so it is essential to support, promote and work each and every day with the producers of renewable energies.

In Holaluz, our DNA is green

  • We represent renewable production plants on the market, helping them to reduce their costs and increase their revenues, which is a fundamental step to transforming the entire system toward clean energies.
  • All the energy that we offer is clean so that the more clients we have, the more we'll support renewable energies.
  • Through the CNMC, we certify that the energy from our producers is 100% green and that's what we sell to our clients with no exception.

We want to take this journey with you.

For us, the present of the energy sector has gone past its expiration date and we're now here building the future.

We want all electricity consumers to be able to generate their own energy (photovoltaic plates, windmills...).

Installing solar panels at home is only the beginning.

We here at Holaluz are going to be the energy exchange platform that will make it possible for users who are producing more energy than they need to be able to place it in our system allowing other users to "reserve" it.

We also support self-consumption

We strongly believe in self-consumption. As a power company seeking to change the sector (and the world!) we must give it our full support.

So we defend the net balance, which is based on the possibility that a user who produces their own green energy at home with their own solar panels or wind turbines can still have a contract with an electricity marketer at the same time.

The balance is established so that if users produce more green energy than they need at any given time, the excess energy is sent back into the general grid. If it's the other way around, users obtain the energy which they're missing through their power company.

This would be a possible starting point. But there's a long road ahead of us and we want to do it together with the people who entrust their energy to us.

Green gas from Holaluz.

The day when the entire market can be supplied with renewable energy and our clients can provide their own power, we'll stop providing gas. In the meantime, we need to offer this option because otherwise it would be irresponsible.

Using clean and manufactured energy, like electricity, to heat up a house or to get hot water is a loss in terms of efficiency. It's best to convert the gas which arrives to the house directly into heat rather than having to process the energy twice to get the same result.

We offer Gas as a complementary service for our electricity clients because it's logical and it's what they need.

This is where we obtain your energy

48% Energy Recovery

This is the name of an energy source, the least well known source.


Wastes contain energy and this process takes care of two things: recovering this inherent energy and also preventing the process of degradation. The wastes that are used are paper, cardboard, plastics and some organic wastes.

We owe it all to him; light is life and the sun is the origin of it all.


Solar energy reaches us mainly in the form of light, heat and ultraviolet rays. Solar panels take advantage of this inexhaustible energy source through thermal conversion or photovoltaic conversion. This is why there are two types of equally efficient solar panels: thermal panels and photovoltaic panels.

Use the useless to create something new; this is the principle of biomass. It is a renewable energy source which is obtained by using organic materials of vegetable or animal origin, residues and organic wastes.


Energy is obtained through the organic matter from waste waters or sewage, as well as the organic part of the solid urban wastes, or wastes derived from industries.

The power of water. By accumulating water in reservoirs and dams and freeing it at once, the movement generates electrical energy inside of hydroelectric plants.


Hydraulic energy is a clean and easily-stored energy source which only depends on the weather conditions to be operating at full capacity.

Certified 100% guaranteed renewable origin

That's what it's called. This is the official certification that we have to explain that we are 100% green energy. The certified 100% guaranteed renewable origin (GDO) is issued by the CNMC (National Commission on Markets and Competition)

To be able to provide us these certificates, every six months the CNMC confirms that, at a minimum, in Holaluz, we present the same volume of renewable energy as the amount that we need in order to satisfy our clients' demand.

The guarantees are requested one year after you have enjoyed your electricity in Holaluz. In fact, it's something that you can verify yourself.
