A modern, large commercial wind turbine with a rated power of 2 MW can generate approximately 2,000 kWh (2 MWh) in an hour under perfect wind conditions. They can produce millions of kilowatt-hours of electricity annually, with the ideal wind speed being 6-9 miles per hour (mph). [PDF Version]
Do wind turbines include blades
They typically have three blades and operate “upwind”, facing into the wind. The main components of a wind turbine include propeller-like blades that act like an airplane wing. Wind turbine blades are the most important component as they catch. .

How does a leaf generator work?
Determines the amount of deformation removal (“Season:Curl” and “Season:Fold”) applied to the fallen leaves. Randomizes the orientations of leaves on the ground. If you have a force mesh applied to the leaf generator, fallen leaves will adhere to it instead of the ground.
What is a tree-shaped windmill system?
Therefore, a tree-shaped windmill system whose leaves act as mini wind turbines is capable of providing power with autonomy and ecology. French company (New Wind) has created the Wind Tree, a 3-meter-tall generator designed for urban environments which makes the most of smaller air currents.
How does a leaf reshape work?
When enabled, leaves will be placed directly on the skin of their parent (as opposed to being anchored on their spine). When enabled, leaves are rotated so that they are perpendicular to the original leaf placement. This is a shortcut for creating crossed, intersecting meshes that have the same position.
Why is a wind tree better than a larger wind turbine?
While The Wind Tree is slower to harness energy than larger wind turbines, it is actually able to generate more energy in the long run because it can operate more often and can catch wind at nearly any force.
