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.

The association between wind turbines and health effects is highly debated. Some argue that reported health effects are related to wind turbine operation [electromagnetic fields (EMF), shadow flicker, audible noise, low-frequency noise, infrasound]. Others suggest that when turbines are sited correctly, effects are more likely attributable to a number of …
