Using the Earth’s underground temperature to produce heat or electricity: that is the principle behind geothermal energy. Less well known than solar and wind energy, it is nevertheless the third most widely used renewable energy in France. This is how it works.

How can more environmentally-friendly fuels be produced for cars, trucks, planes and boats? The answer lies in advanced biofuels and e-fuels! Produced from plant residues, organic waste, renewable electricity associated with CO2 molecules captured in the atmosphere or...

The vehicle is equipped with a combined IC/electric powertrain system and two energy storage systems: a fuel tank and a battery.

Bio-based chemistry is chemistry in which fossil resources are partially or completely replaced by resources derived from biomass. In particular, it helps limit reliance on fossil resources for the production of certain types of products and reduces the environmental footprint of these products.

Technologies have progressed significantly and a whole host of different wave energy systems are in the process of being developed to convert this resource into electricity.

Sailing boats, windmills, etc. Humans have made use of wind energy for centuries. Thanks to technological progress, today it is possible to produce “green” electricity without using fossil resources. We take a closer look at its development prospects and the remaining challenges to be overcome.

Since they were invented, cars have mainly operated with 4-stroke internal combustion engines. In Europe, these have either been gasoline (spark ignition) or diesel engines.
