- high power, geared transmissions were developed centuries ago by windmill designers
- Dependent on wind speed & direction
- Too little force no power
- Too much force damage to infrastructure
- Blades on turbine turn as wind blows
- Rotates shaft connected to generator
- Spinning magnets of generator convert rotational energy into electricity
- Minimum wind speed: 10-15km/h
- Turbine cut out: 90km/h
- Turbine performance is exponential
- Wind speeds of 30km/h 8x more productive than winds of 15km/h
- Two main categories
- Onshore & Offshore
- Offshore advantages more wind
- Offshore disadvantages higher costs
- Efficiency 20-50% for modern turbines
