Wind turbines(风力发电涡轮机) and solar panels that generateelectricity are examples of "green” technology. A new study finds that such renewable energy might be green inanother sense. Large collections of those turbines or solar panels appear capable of bringing rain to the desert andwould allow...
Wind turbines (涡轮) and solar panels (太阳电池板) that produce electricity are examples of “green” technology. A new study finds that such renewable energy might be green in another sense. Large collections of those turbines or solar panels appear capable of bringing rains to the desert and...
Wind tunnel testing of airfoils is an indispensable part of the wind turbine design process. Especially very large wind turbines with 100m+ blades demand robust airfoils with highly accurate aerodynamic data during the design phase which requires special attention for wind tunnel testing. This chapter...
While they were hailed as an alternative source of renewable energy in the past, research has suggested that the noise and effects of wind turbines on humans and wildlife can be quite adverse. This includes not only birds dying due to collisions with the turbines but also the noise pollution ...
Since the batteries in these cars can also be used to store the carbon-free energy that can be utilized by home-based solar cells and wind turbines, these vehicles could dramatically transform the way we light and heat our homes. In a real sense, your car battery could be your home’s ...

Companies and organizations seeking more sustainable energy sources have a number of ways toprocure renewable energy. They can invest in and install their own equipment, from solar panels to wind turbines, for on-site generation. Many utilities offer the option for companies to purchase green power...

Typically, wind turbines don’t produce emissions capable of polluting the air or water. Also, they don’t need to be cooled by water. Though rare, they can have some negative effects on the environment if they leak lubricating fluids or catch fire. They can also negatively impact bird life...
