• Faced with the climate challenge, what response, what solution and what system can reduce greenhouse gas emissions and reduce our energy consumption?


A balanced mix that is adapted to uses, geographies and environmental impact.

ENGIE is committed to:

  • Saving energy and reducing consumption by improving energy efficiency in buildings, in industry, in urban infrastructures and in how we travel,
  • Decarbonizing the energy mix by exploiting each form of energy’s greening potential: gas and green gas (biomethane and hydrogen) and renewable electricity.

In a few weeks’ time, through the Multiannual Energy Plan and the French National Low-Carbon Strategy, France will decide on its choices with respect to its energy policy for the period 2018-2028, with the target of achieving carbon neutrality by 2050.

At ENGIE, we firmly believe that the energy transition has to be a driver of harmonious development towards a world that is increasingly decarbonized, decentralized and digitalized, in which the share of each energy will vary from one geography to another and will depend on the resources available locally. It will be a mixed world in which large energy infrastructures combine with small local structures consisting of renewable energies, energy storage and micro-networks.

In our opinion, the energy transition will only succeed if we are able to combine the strengths of all sources of energy. The true solution, the right compromise, is based on the various energy vectors – electricity, heating and cooling networks and gas – complementing each other to obtain the greatest benefit from each one and ensure that the energy system is both reliable and flexible.

Un mix énergétique où le gaz et le gaz vert ont toute leur place

An energy mix where natural gas and green gas have their place

At a time when the energy landscape is looking less carbon-intensive, natural gas is positioned in the future energy mix as the energy of transition: it is abundant, low carbon and can be a real partner for renewable energies.

What is the energy mix?

To satisfy its energy needs, every country uses the energies it possesses in different proportion. This is what we call the energy mix.

For each region or country, the composition of the energy mix depends on:

  • the availability of usable resources produced locally or importable;
  • the scale and nature of the energy needs that have to be met;
  • political choices stemming from the historical, economic and social, demographic, environmental and geopolitical context.

The energy mix defines the distribution of the different primary energy sources (nuclear, coal, oil, gas, wind, etc.) used to produce a clearly defined amount of energy. The share of each primary energy source is expressed as a percentage. These primary energies are used to produce electricity and fuels for transportation, heat or cold for housing and industry, etc.
