4. Population density for Great Britain: 250 people / km2 in kWh/day: ?

5. Population density for Great Britain: 250 people / km2 in kWh/day: 200 kWh/day

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

7. Be realistic and assume that only 10% of the land in Great Britain If we want wind power to truly make a difference, thewind farms must cover a very large area.

8. Importance of Averaging

9. Estimate potential wind energy production in Turkey.

10. Estimate potential wind energy production in Turkey. Total area: 814.578 km2 Total Population: 80 million

11. Estimate potential wind energy production in Turkey. Total area: 814.578 km2 Total Population: 80 million = 2 W/m2 x 10000 m2/person = 20 kW/person = 480 kWh/day-person

15. 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 windspeed is one third of the arriving wind speed, the power extracted is 16/27of the total power in the wind. 16/27 is 0.59.In practice let’s guess that awindmill might be 50% efficient.

19. Variation of wind speed with height
