Preface  daily power consumption  kilowatt-hour (kWh) = electricial power (watt=W) times power-on time (hour=h)  1 kilowatt-hour equals watt-hours (kWh)  example to describe power per time unit (e.g. watch TV for 15 hours or work 7 hours on the laptop)

1. fundament 2. tower 3. engine pod 4. rotor blade 5. hub 6. transformator Structure

 modern constructions  4 mill. - 7 mill. kWh per year.  produced power of a construction depends on : › the height of the hub › diameter of the rotor › speed of the wind › topograhpy › the site

 Offshore windengines produce less energy than those near the shores or on shores  the bigger the engine the more it produces

 A big, modern wind engine produces 6 MW  medium sized nuclear power station  1200 Megawatt  200 modern wind engines = 1 nuclear power station

These are : 1374,3 MW

900 engines produce MW. This is enough energy for over one Million houses!
