» What is renewable energy?
Energy generated from sources that by their very nature are replenished or cannot be depleted in the foreseeable future of humankind is classified as “renewable energy”.
The use of renewable energy does not jeopardise natural resources for future generations (unlike traditional energy sources, which are not renewable and will eventually run out, such as oil, natural gas and coal). The classification of energy sources is often inconsistent and often the term “alternative energy” is used because the sources are “different” from “traditional” or “conventional” ones.
Therefore, “renewable energy sources” are usually considered to be: the sun (thermal and photovoltaic solar energy), wind (wind power), the sea (tidal power), the heat of the Earth (geothermal energy) and water (hydroelectric power).
» Which renewable sources does ERG use to produce electricity?
At present, ERG, through its subsidiary ERG Renew, produces electricity from wind energy; this is produced and converted on its wind farms in Italy, in France, in Germany and in Bulgaria , giving a total installed capacity of 1.232 MW. ERG Renew is also participating in a next generation solar power (so called organic photovoltaics) research and development project.
» How is electricity obtained from the wind turbines?
Wind farms consist of wind-power generators that can transform the kinetic energy of wind into mechanical energy, which is used in turn to generate electricity.
