The way to more efficient, quieter wind turbines
It may sound strange to anyone who lives in the vicinity of one or more wind turbines, but wind currently represents just  4.5-5% of the renewable energy supply in the world.
Wind turbines: new device to reduce noise and increase efficiency
Wind turbines: new device to reduce noise and increase efficiency
Noise pollution is one of the main public concerns associated with operating wind turbines. To tackle this problem, technicians at a Spanish windfarm near Burgos are assembling a new device on the blades.
Clean and affordable: the wind energy challenge
Clean and affordable: the wind energy challenge
On 22 April , it is world Earth Day . The idea is to raise awareness of the need to rely on renewable energy. The EU requires its member states to provide a a 27% share of renewable energies by 2030—up from a 23.
