In order to combat global warming, structural changes in terms of production and consumption are necessary to reduce emissions of greenhouse gases. One of the main paths explored by research laboratories is to promote the use of non-conventional and renewable energies, or even nuclear energy. The laboratories of Grenoble INP are thus carrying out research in the field of solar, wind and hydro energy. For example, the LEGI has recently signed the Hydro'like industrial research chair, in partnership with Alstom and the Grenoble INP Partnership Foundation, to develop the hydroelectric power of the future. Its ambition is to develop turbines that will respond to increased demands for flexibility of operation. In parallel to these channels that are being developed to meet the growing demand for electrical energy while limiting carbon emissions, nuclear power retains its key position in industrialised countries and is developing in new countries. Since 1955, Grenoble INP - Phelma has offered training to cover all the needs of the sector. Its purpose is, on one hand, to extend the life of existing nuclear power plants while meeting all the necessary criteria of safety and reliability, and, on the other hand, to prepare for the future by participating in the development of the EPR and the fourth generation of nuclear reactors.
