Problems with wind turbines.
The average cost of a small roof-mounted turbine (between 0.5 kW to 2.5 kW), is about £2,000 5. But these don’t generate very much electricity, so it will take a very long time to recoup that cost. On average, a free-standing 5kW wind turbine may cost between £20,000 and £25,000.

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.The future of wind energy in the US is floating turbines as tall as 30 Rock.
