1. Wind

3. W per person ? Population density for Great Britain: 250 people / km 2

4. in kWh/day: ? Population density for Great Britain: 250 people / km 2

5. in kWh/day: 200 kWh/day Population density for Great Britain: 250 people / km 2

6. Be realistic and assume that only 10% of the land in Great Britain

7. If we want wind power to truly make a difference, the wind farms must cover a very large area.

8. Importance of Averaging

9. Estimate potential wind energy production in Turkey.

10. Total area: 814.578 km 2 Total Population: 80 million

11. Estimate potential wind energy production in Turkey. Total area: 814.578 km 2 Total Population: 80 million = 2 W/m 2 x 10000 m 2 /person = 20 kW/person = 480 kWh/day-person

14. The Physics of Wind Power

16. The windmill slows the air down quite a lot, but it has to leave the air with some kinetic energy, otherwise that slowed-down air would get in the way. If the departing wind speed is one third of the arriving wind speed, the power extracted is 16/27 of the total power in the wind. 16/27 is 0.59. In practice let’s guess that a windmill might be 50% efficient.

19. Variation of wind speed with height
