ABSTRACT
This chapter, which is the longest in the book, seeks to provide the reader with technical bases on energy: it briefly presents the energy supply, that is to say the different energy sectors. After describing the different forms energy takes and explaining the possible modes of conversion between them, it introduces the main characteristics of these sectors, starting with fossil fuels (oil, natural gas, coal, synthetic hydrocarbons), followed by nuclear, power generation and renewable energies (geothermal, solar, wind, hydro, marine energy) and finally presenting the thermal or pneumatic storage.
