The Energy Sector relates to the production and supply of energy. Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, and waves. Renewable energy replaces conventional fuels in four distinct areas, electricity generation, air and water heating/cooling, motor fuels, and rural (off-grid) energy services.
The Energy Sector is very closely linked with engineering, manufacturing and ports & logistic sectors.
