Wind Turbines

What is a renewable energy source?

• Nuclear energy

• Solar, wind, hydro, geothermal, and biomass energy

• Coal, oil, natural gas

• Wave energy

How does wind energy technology work?

• Wind energy is produced by burning fossil fuels

• Wind energy is generated by using wind turbines to convert the kinetic energy of wind into mechanical power, which is then used to generate electricity.

• Wind energy is created by harnessing the power of the sun

• Wind energy is generated by using water turbines

Why is environmental impact assessment important for wind turbines?

• To increase the cost of energy production

• To promote the use of fossil fuels

• To reduce the efficiency of wind turbines

• To evaluate potential effects on wildlife, ecosystems, and local communities and mitigate any negative impacts.

What are the key components of a wind turbine design?

• Rotor blades, nacelle, tower, control system

• Gearbox, generator, foundation, pitch system

• Blade pitch system, yaw drive, gearbox, generator

• Anemometer, wind vane, wind speed sensor, power converter

How is electricity generated from wind in a wind turbine?

• Wind creates a magnetic field that generates electricity directly

• Wind activates a chemical reaction in the turbine to generate electricity

• Wind turns the blades of the turbine, which spins a generator inside the turbine.

• Wind compresses air in the turbine to produce electricity

What are the advantages of using wind energy as a power source?

• Limited availability

• High maintenance costs

• Renewable, abundant, no greenhouse gas emissions, cost-effective, versatile

• Inconsistent power output

Explain the concept of wind turbine efficiency and its significance.

• Wind turbine efficiency has no impact on electricity generation

• Wind turbine efficiency is crucial as it directly impacts the amount of electricity generated from wind energy, affecting the overall cost-effectiveness and environmental benefits of wind power.

• Wind turbine efficiency is determined by the color of the blades

• Wind turbine efficiency only affects the appearance of the turbines
