But the Darrieus models use an airfoil design. Multi-megawatt wind turbines aim for a low nacelle head weight and a minimum cabling effort between the generator, converters and transformer. Worldwide interest in renewable energy options has given rise to a rash of new wind turbine designs. The result is that generating an extra kilowatt hour kWh of electricity from an operating solar panel or wind turbine costs close to zero $0.00 / kWh. Harnessing the wind's energy is the objective of a new project, which aims to provide an important breakthrough in offshore wind industrial solutions. A wind turbine airfoil works in the same way as an airplane wing. €�Vestas and Gamesa designed their turbines around the use of carbon fiber and, by virtue of that, the whole system cost is less than a system with an all glass-fiber blade,” confirms Dr. Schell, executive VP of wind energy at carbon fiber manufacturer Zoltek Corp. Offshore turbines are moving quickly from 3 MW to next-generation turbines rated at 5 MW and larger, on which blade lengths for both on- and offshore systems regularly exceed 45m/148 ft. An airfoil has a flat side and a curved side. Some of the most recent models on the market are vertical axis wind turbines (VAWTs), which manufacturers claim are quiet, efficient, economical and perfect for residential energy production, especially in urban environments.
