Energy efficiency and energy transition
Decarbonization refers to the collection of measures and techniques developed to reduce the carbon content of energy, and particularly its CO2 content. The development of these decarbonized technologies is an essential element of the ENGIE strategy: to ensure continuity of clean energy supplies for consumers, the Group is constantly diversifying its power generating base by incorporating sources of renewable energy, such as wind power, solar power and biomass.
The decentralization of power generation consists of prioritizing a large number of small generating units close to end-user consumers, rather than large-capacity generating plants on a single site. This concept of bringing local communities, customers and consumers closer together is radically changing energy systems. One of the characteristic features to emerge from the development of renewable power generating technologies is the miniaturization that makes decentralization possible and desirable.
The digitalization of energy made possible by the convergence of digital and energy technologies gives everyone the power to manage their own energy consumption using smart meters, for example.
- Carbon dioxide
This is the main greenhouse gas present in the Earth’s atmosphere. Produced as a result of natural processes, it can also be released by complete combustion of the carbon contained in fossil fuels.
- Energy efficiency
Energy efficiency is all about consuming more efficiently, so that we use less energy to receive a similar level of service. You can, for example, minimize the amount of energy you use for heating by upgrading the installation of your home. Being more energy efficient also means using new technologies to manage energy consumption more effectively. Remote boiler programming makes it possible to avoid the need to heat homes continually, for example.
- Greenhouse gas
An atmospheric gas that contributes to retaining the sun’s heat within the Earth’s atmosphere. Industry, cars, heating and farming all produce gases, and some of those gases have the result of increasing the greenhouse effect. The considerable increase in greenhouse gases as a result of human activity is one of the causes behind global warming and its consequences for our ecosystem.
The abbreviation of greenhouse gas.
- Energy mix
The energy mix refers to the collection of different energy sources used to meet the energy consumption needs of a given area and their relative proportions. ENGIE is committed to investment in diversifying its energy mix as a solution to effectively meet a very diverse range of local needs, at the same time as reducing the overall impact of human activity on the environment.
- Green mobility
Green mobility refers to the combination of technology solutions like electric vehicles and changes in our personal mobility habits that together contribute to reducing the amount of energy used to transport people and freight, and therefore to cutting greenhouse gas emissions.
- Energy poverty
Energy poverty describes the status of individuals or groups of people who have insufficient and/or irregular access to the energy sources required to meet their basic essential needs, whether at home or in their wider living environment.
- Security of supply
The guarantee of having access to the desired quantity and quality of energy under a given set of economic conditions.
- «Smart grids» ou «réseaux électriques intelligents»
Smart grids are intelligent power distribution networks managed automatically in real time to deliver more effective energy management in terms of both consumption and generation. As powerful management tools, smart grids make it possible to generate and consume electricity in much smarter ways, and therefore make a valuable contribution to the energy transition.

- Energy conservation
Energy conservation involves avoiding waste, but it also means changing our habits by – for example – using public transportation and/or vehicles fueled by gas or electricity.
- Energy storage
Energy storage refers to the storage of a given quantity of energy in a particular location in preparation for use at a later time. One of the twin aims of energy storage is to limit losses. The other is to use the stored energy to adapt more effectively to demand, especially at times of lower generating level. Energy saving solutions are also essential to offset the intermittent nature of renewables.
- Energy transition
The term energy transition refers to the process of moving away from the current model of energy generation with its main focus on non-renewable sources of energy (oil, gas, coal, etc.) to an energy mix in which the majority of sources are renewable. This involves introducing innovative technologies and practices to reduce the impact of energy generation on our planet, and building a new, more sustainable model that successfully meets our environmental challenges.
Did you know ?
In terms of energy efficiency, the 3 Ds – the decarbonization, decentralization and digitalization of energy systems – are the cornerstones of the transition to a low-carbon economy.
- Energy recovery unit
A waste incineration plant that recovers energy in the form of heat (for district heating networks and/or as steam for industry) and/or electricity.
The processes involved in reusing or recycling waste, materials or energy. A distinction is made between:
- energy reclamation: recovering the calories contained in incinerated waste to generate energy in the form of heat or electricity
- materials reclamation: processing waste in such a way as to enable the re-use or recycling of materials
- biological reclamation: using composting or methanation to treat organic waste
- The 3 Ds
This abbreviation is based on the belief that tomorrow’s energy model will be a 3D model: Decarbonated, thanks to the development of renewables, Digitalized through the introduction of smart grids, and Decentralized for greater energy self-sufficiency. ENGIE has made the Decarbonization, Decentralization and Digitalization of energy systems the basis for its commitment succeeding in the challenges posed by the energy transition..
