Winter is supposed to be the best season for wind power—the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing ...

Further, a HAWT can have upwind- or downwind-type rotors. An upwind turbine has its rotor fixed in front of the unit, directly facing the incoming wind stream (Figure 21). In contrast, the downwind turbines have their rotors positioned at the back side, leaving the nacelle to face the wi...

Offshore wind turbines are considered an important element of the future energy infrastructure. The majority of operational offshore wind turbines are founded on monopiles in water depths up to 30 m. Alternative foundation arrangements, however, are needed for future development rounds in deeper wate...

humpbacks more hydrodynamic when they swim and dive. Harvard University researchers have applied this adaptation to alternative energy—an example of “biomimicry” in technology. The scientists found that wind turbines with bumpy, tubercle-inspired blades generate more energy than traditionally smooth ...

These modern-day windmills convert mechanical energy from the wind into electrical power. Most wind turbines have three main parts: the tower (the long stem that connects to the ground); the blades, which connect to a central hub (the rotor); and the nacelle (a box behind the blades that...
