Tapping of Lost Velocity of Air For Wind Mill with Second Rotor Set -Up

Wind power is more efficient and affordable than it has ever been which has helped drive its popularity. I is important to understand that greater use of nation’ s abundant wind resources for electric power generat ion will help stabilize energy costs, enhance energy security, an d improve our environment. Also, wind energy has been of prime importance as wind turbines can be used as stand-alo ne applications, or they can be connected to a util ity power grid or even combined with a photovoltaic (solar cell) syste m. For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form a wind plant. Several electricity providers today use wind plants to supply power to their customers. Recent studies have highlighted the negative impacts of its use of envi ronment and life especially on birds. But there should be a trade-off between its use and its impact.
