Our commitment to energy efficiency

Energy efficiency is a basic tool of environmental quality. That is why the activities of the Naturgy Foundation focus on promoting information, training and raising public awareness of improved energy efficiency and technological innovation in relation to energy, in a way that is consistent with respect for and protection of the environment. These include the Energy Efficiency Studies which are carried out periodically to check the capacity for energy improvement in homes and Spanish SMEs.
