01 How It Works
Wind turbine blades act like airplane wings - as wind flows over them, it creates lift that spins the rotor. This rotational energy is transferred via a gearbox (or direct drive) to a generator. Modern utility turbines stand 150โ260 metres tall with blade spans exceeding 200 metres, capable of generating 15+ MW each. Offshore turbines take advantage of stronger, steadier coastal winds.
02 Pros & Cons
โ Advantages
- Zero fuel cost
- Low lifecycle emissions
- Offshore potential is vast
- Land can still be farmed
โ ๏ธ Disadvantages
- Variable output
- Noise and visual impact
- Bird/bat mortality
- Best sites often remote
03 Future Outlook
Floating offshore wind technology is opening up vast deep-water areas previously inaccessible. Airborne wind energy (kites, high-altitude turbines) and bladeless vortex turbines are emerging niches. Wind is projected to supply 35% of global electricity by 2050 under net-zero scenarios.
04 Fun Fact
A single modern offshore wind turbine can power over 15,000 homes for a year.
