The technology of renewable energy exploits nature's fuel such as sunlight, wind and water to provide a sustainable source of power. It captures, stores and releases in ways that minimize ENVIRONMENTAL impact huge amounts of electricity: So it is not just production technology but also a form of usage philosophy for lighting up the world. Technological features vary by type: photovoltaic cells in solar panels, turbines at wind farms and dams on hydroelectric power stations etc In addition, they are designed to be simple and efficient with other intelligent features. Their uses are widespread, from residential solar systems to large wind farms that power whole communities. This shows their versatility and importance in the transition to a greener future as we nned to pay attension for our living century to happen.
