Energy Labeling

The electrical energy we consume is different from that consumed by our neighbors or other consumers connected to the same electrical system, so it is very important to provide this information to our customers. This way it is possible to present the origin of the production of electrical energy that it actually consumes.

Why is Audax concerned about the type of electricity it sells?

The impacts of the electrical energy we consume depend on the sources used in its production.

Audax, as an energy trader, plays a fundamental role in promoting renewable energy and the use of thermal production from fossil fuels with a lower carbon content, as well as improving efficiency in emissions, transport and the final use of energy. This way we offer our consumers green energy, at no additional cost. Another way to help the environment is by avoiding paper waste, so Audax calls for the use of electronic invoices.  

Renewable energies (sun, wind, and waves) have less harmful impacts on the environment and the population, as there is no emission of greenhouse gases and polluting gases into the atmosphere. However, renewable energy can have some impacts on the landscape, habitats and ecosystems, which are minimized through careful selection of the most suitable site and project.

The same does not apply to non-renewable energy, where the use of fossil fuels (coal, gas and oil) releases polluting gases such as carbon dioxide (CO2), nitrogen oxides (NOx), dioxide and sulfur (SO2). ) and carbon monoxide (CO). The emission of these gases has an environmental impact on the greenhouse effect, contributing to the intensification of global warming and climate change.

Environmental impacts – Curiosities

What do greenhouse gas emissions consist of?
Carbon dioxide (CO2) is the main gas resulting from emissions (60%), produced when burning fossil fuels, such as coal, gas or oil. CO2 is naturally assimilated by plants and transformed into oxygen in the well-known process of photosynthesis, however the abnormal amount of this gas emitted into the atmosphere today and throughout the 20th century and continuous deforestation makes the natural cycle carbon dioxide is unregulated, causing what is also known as global warming.

What is and what are the consequences of global warming?
Global warming is a phenomenon characterized by climate change and the increase in the planet's average temperature.
The consequences of global warming include melting ice, rising ocean levels, desertification, changes in rainfall patterns, floods and a reduction in biodiversity.

What are the tools to reduce emissions?
They are varied.
They include electrical production through clean and renewable sources, such as wind, solar and hydropower, as well as new CO2 capture and storage technologies.

Energy Source Categories:

To the renewable energy are obtained from Nature. They regenerate themselves, like the Sun or the Wind.

 Renewable energy



Renewable cogeneration


Other Renewables


  • Wind: energy obtained by the action of the wind, which can be converted into electricity using wind turbines;
  • Hydro: energy obtained by the action of water, which can be converted into electricity by taking advantage of rivers, tides and waves, such as dams;
  • Renewable cogeneration: combined production of thermal energy and electrical energy, using non-fossil resources as fuel;
  • Geothermal: energy obtained from the Earth, which can be converted into heat to heat the environment and water;
  • Other Renewables: production of electrical energy based on renewable energy sources such as: solar energy, Biomass, Biogas; Waves and tidal waves.

Non-renewable energies These are energy sources that are present in nature in limited quantities, that is, they cannot be renewed if they run out.

Non-Renewable Energy

Fossil cogeneration

Natural gas



Fuel oil



Fossil cogeneration: combined production of electrical and thermal energy, using fossil resources as fuel;

Urban solid waste may or may not be renewable energy.
