If we keep subsidizing wind, will the cost of wind energy ...

Wind costs follow what economists call a learning curve: For every doubling of wind production, the cost goes down by a fixed percentage. For example, if the price of electricity from wind is 10 cents per kilowatt-hour with a given number of wind farms, a 10 percent "learning rate" means that wind electricity would cost 10 percent less, or 9 cents per kilowatt-hour, if one doubles the ...

The propeller produces airflow, which turns helically around the fuselage of the aircraft. For conventional aircraft this means that there's a kind of "wind" pushing on the side of the vertical stabilizer, which causes some yaw tendency. All of these are corrected with a bit of right trim in the ailerons and rudder, or compensated for manually.

Vertical Axis Wind Turbine: All You Wanted to Know

Vertical Axis Wind Turbine (VAWT) A wind turbine cannot be a wind turbine unless it has few blades. Likewise, the horizontal axis turbines, vertical axis ones also have a set of blades. But instead of spinning horizontally, they spin vertically. So, the rotational axis of a VAWT is in the vertical direction, and that's why it got such a name.
