Constructing forward-looking visions

Updated 08/26/2021

ADEME leads forward-planning efforts that contribute to defining the focus and priorities of research in its areas of action.


Since 2008, ADEME has coordinated groups of experts to establish strategic roadmaps.
These technological roadmaps are the result of the collective work of experts from ADEME, industry, research bodies, institutes, public authorities, consulting firms and associations. The strategic roadmaps present the shared visions of how technology will be rolled out to meet the major environmental, economic and societal challenges of the future.

Scenarios for 2030-2050: A proactive vision of energy

Work is being undertaken to gain a future perspective on different challenges relating to the ecological transition.  This work determines a path for the energy transition that corresponds to France's economic and energy reality. The scenarios for 2030-2050 put forward
  • a projection, applicable from the present day, which seeks to maximise the possible energy savings and renewable energy production in an ambitious but realistic manner, until 2030;
  • a normative projection, which aims to achieve a fourfold reduction in greenhouse gas emissions generated in France by 2050 (Factor 4).
The 2050 scenario shows it is possible to achieve Factor 4 and that the road to sustainable growth can be found by supporting the green economy, and by opening to the business sectors of the future such as energy efficiency, renewable energy production, energy recovery from waste, recycling and eco-design.

The lifestyles of 16 witness families

The day-to-day lives of 16 families living in 2030 and 2050 have been set out to underline the diversity of possible lifestyles in a future based on a system with low use of highly renewable energy. The diversity of households' situations and individual lifestyles is matched by a range of alternatives and solutions that, when combined, enable the collective greenhouse gas emission reduction target to be achieved.


A 100% renewable electricity mix? - Analyses and optimisations

After publishing its energy transition scenarios 2030/2050, ADEME achieves a technical study testing various electricity mixes to ensure the electricity grid is balanced when the share of renewable electricity generation is massively increased.
This study is based on an advanced optimisation of electricity system that seeks to ensure balance between supply and demand on hourly basis and searches for the lowest cost. Thus, it identifies the technical measures to be implemented (strengthening electricity grids, load shedding and storage) to support a policy of growth in renewable electricity generation. It is also being used to identify the key factors for developing renewable technologies at lower cost such as lower costs of technologies, demand-side management, development of flexibility, support of R&D of least-mature technologies and the social acceptance of renewable electricity installations.
