Renewable Energy Sources are the first energy sources humanity used long before fossil fuels like coal or petroleum. The need to develop technologies for the exploitation of renewable energy sources arose after the energy crisis of the 1970s. They are energy sources abundant in nature, practically inexhaustible, found everywhere (geographically), have relatively low operating costs and, most importantly, are environmentally friendly.
Their utilization depends exclusively on the development of reliable technologies for benefiting from their potential. They are an excellent solution for saving money and contributing significantly to the energy balance of the planet. The main forms of renewable energy sources are solar energy (through solar panels), geothermal energy, wind power (through wind turbines), biomass energy and marine energy.
