The front of the blade is referred to as the leading edge and the back is referred to as the trailing edge, as illustrated in Figure 1a. Figure 1 Air Moving Past a Turbine. . The performance, efficiency, and lifespan of a wind turbine largely depend on its blade design and construction. The aerodynamics behind blades are not simple; they are closer to aircraft wings. . The blades are the turbine's “catchers' mitt. A poor blade design means wasted wind, higher stress on components, and lower energy output. On an airplane wing, the top surface is rounded, while the other surface is relatively flat. . The tower stands 80 meters tall, and that's not including the blades, which make it taller still. It is an upright, cylindrical structure, several meters in diameter, tapering as its height increases. This is the most common modern tower.

How much does electricity cost in Portugal?
Starting January 2025, electricity price in Portugal increased by 2.1%, as reported by Idealista. This rise is linked to inflation and adjustments in energy production costs.Currently, residential electricity prices range from €0.20 to €0.25 per kilowatt-hour (kWh), depending on consumption levels and providers.
Why do electricity prices fluctuate in Portugal?
This dependency makes prices vulnerable to global energy market fluctuations. Portuguese electricity bills include various fees, such as VAT (6% for basic tariffs) and network maintenance costs. These additional charges significantly impact the final price paid by consumers. Curious about solar panels?
Does Portugal have a green energy plan?
Portugal is building one of the cleanest and smartest electricity systems in Europe. Between surging renewables and flexible tariffs, it's never been easier for households and businesses to go green — and save money doing it. Time to rethink your energy plan?
What is Portugal's energy mix?
Hydroelectric power, benefiting from Portugal's river systems, and wind energy are among the most significant contributors to the country's energy mix. Solar power is also on the rise, taking advantage of the country's sunny climate. Portugal's commitment to renewable energy is evident in its ambitious targets and policies.

For variable speed wind turbines, one of two types of generators can be used: a (doubly fed ) or an FRC (fully rated converter). A DFIG generator draws from the transmission system; this can increase the vulnerability of a transmission system in the event of a failure. A DFIG configuration will require the generator to be a wound rotor; squirrel cage rotors cannot be used for such a configuration.

Wind turbines use blades to collect the wind's kinetic energy. The blades are connected to a drive shaft that turns an electric generator, which produces (generates). . Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn.
