Renewable energies

Shape the future of energy through optimised management of consumption and the adoption of alternative energy sources.

By following the principles of energy sobriety, our primary objective is to reduce energy needs and minimise losses through efficient equipment and practices. In line with this approach, we propose sustainable energy production solutions, favouring local sources wherever possible.

Relying on our in-depth expertise in equipment, as well as in the obstacles and challenges associated with its use, we develop solutions adapted to the resources available such as wood energy, solar, photovoltaic, wind, heat, geothermal, biogas or marine energies. We assess the potential of each energy source, taking into account recovery and storage opportunities. We also offer training and capacity building to develop the skills of public and private organisations.

Training engineering

Become enlightened players in the energy and ecological transition.

Our assistance service includes the transmission of high-level knowledge and skills, tailored to your needs:

For the general public: a comprehensive understanding of energy issues and a technical basis to understand energy systems.

For energy professionals (design offices, craftspeople, corporate energy managers): in-depth technical expertise in equipment, thermal engineering, efficient use of systems, maintenance, regulation, energy audits and energy management. Specialised study trips can be organised with partners.

For elected representatives and public energy services managers: a detailed understanding of the energy potential and constraints specific to each area, tried and tested solutions in similar contexts, as well as a technical basis on energy systems.

For companies: an understanding of the challenges and benefits of energy efficiency, as well as its integration with other environmental aspects such as territorial and industrial ecology, CSR, the circular economy and functionality.
