Wind Energy
Think Small. And Vertical
Unlike the giant windmills erected by utilities, small wind-energy turbines can be used in both rural neighborhoods and urban environments.
Vertical-axis wind turbines (VAWT), like the one shown here, collect wind from every direction, not just one.
They also tend to be safer and easier to build, because they can be mounted close to the ground, and they can handle the complex turbulence created by urban architecture – all while providing a safe, attractive source of “green” energy..
