⚡ Part 1: Wind Energy Science

1. Which blade shape would generate the most efficient energy capture?

Flat rectangular blades

Curved aerofoil blades with twisted design

Triangular pointed blades

Circular disc blades

2. A wind turbine generates 2.5 megawatts of power. How much energy (in kilowatt-hours) would it produce in 24 hours?

3. Which factors affect wind turbine efficiency? (Select all that apply)

Wind speed and direction

Blade angle and pitch

Tower height

Air density and temperature

Nacelle orientation

4. The relationship between wind speed and power generation follows the formula: Power ∝ Wind Speed³. If wind speed doubles from 10 m/s to 20 m/s, the power output will increase by a factor of:

2 times

4 times

6 times

8 times

🔧 Part 2: Design Optimisation Challenge

5. Design an innovative wind turbine for extreme weather conditions. Consider materials, blade design, and safety features. Sketch your design and label key components:

6. Compare carbon fibre and fibreglass as blade materials. Analyse their advantages and disadvantages for turbine performance:

7. A wind farm needs to power 50,000 homes. Each home uses an average of 25 kWh per day. If each turbine generates 3 MW at 35% capacity factor, how many turbines are needed?

🌍 Part 3: Innovation and Critical Thinking

8. Propose three innovative solutions to overcome the challenge of intermittent wind energy (when wind doesn't blow consistently):

9. Environmental impact assessment: Discuss both positive and negative effects of large-scale wind farms on ecosystems and communities:

10. Future innovation challenge: Design a wind turbine system that could work effectively in urban environments. Consider noise, space constraints, and efficiency:
