Wind Turbine Technology
Wind turbines convert kinetic energy in moving air into electrical energy. Modern turbines are engineering marvels—the largest have 260-meter rotor diameters (taller than the Eiffel Tower) and generate 15MW each.
The Power Curve: Wind turbines have three key speeds:
- Cut-in speed (3-4 m/s): Minimum wind to generate power
- Rated speed (12-15 m/s): Produces maximum rated power
- Cut-out speed (25 m/s): Turbine shuts down for safety
The Betz Limit: Physics dictates that no wind turbine can extract more than 59.3% of wind's kinetic energy (Betz Limit[W1]). Modern turbines achieve 45-50% efficiency, approaching this theoretical maximum. This isn't poor engineering—it's fundamental physics. If you extracted all the wind's energy, air would stop moving and couldn't carry more energy to the turbine.
Capacity Factors
| Location Type | Capacity Factor | Annual Hours |
|---|---|---|
| Onshore (Average) | 25-35% | 2,200-3,000 hours |
| Onshore (Best Sites) | 40-50% | 3,500-4,400 hours |
| Offshore (Average) | 40-50% | 3,500-4,400 hours |
| Offshore (Best Sites) | 50-60% | 4,400-5,300 hours |
Offshore wind has higher capacity factors because ocean winds are stronger and more consistent. However, installation and maintenance costs are 2-3x higher than onshore. The economics work because of superior production—an offshore turbine might generate twice as much energy as the same turbine onshore.
💡 Multiple Revenue Streams Through Tokenization
Wind farms generate revenue through multiple streams: electricity sales (70-80%), renewable energy certificates (10-15%), capacity payments (5-10%), and ancillary grid services (2-5%). Traditional investors capture all these revenue streams. Tokenization enables everyday investors to access the same diversified cash flows that previously required $50M+ commitments.
