Wind turbines(风力发电涡轮机) and solar panels that generate 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 rain to the desert and would ...
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...
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 ...
Thesis Statement: Wind turbines need to be replaced with alternative sources of green energy due to their hazardous effect on human health and wildlife. The above statement makes a case against wind turbines. While they were hailed as an alternative source of renewable energy in the past, researc...

Power is defined as work per unit time. Sources of power in the real world abound. Muscles make a body lift weights, combustion engines propel a car and wind turbines spin generators. The phrase "electric power" specifically refers to power generated by
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...
