Renewable energy (RE) sectors can be known by different names such as marine energy, solar PV energy and wind energy. These sectors generate electricity from renewable natural sources. They consist of complex arrangements of sub-systems, including structures installed outside without protective environments. Direct interaction with the natural environment affects the reliability and performance of these systems.
 
These sectors include the equipment and processes to produce energy, as well as the equipment to manufacture, transport and service the energy-producing equipment. Relevant standards exist for specific industry sectors to which the conformity assessment and certification of the IECRE System is provided.
