1. Wind Energy Is a Renewable Source
Wind energy is renewable and sustainable — it will never run out as long as the sun shines and the Earth rotates.
2. Wind Is Caused by the Sun
Wind forms due to uneven heating of the Earth’s surface by the Sun, which creates pressure differences — wind turbines capture this natural movement.
3. Wind Turbines Convert Kinetic Energy to Electrical Energy
Wind energy works by converting the kinetic energy of moving air into mechanical energy, and then into electrical energy using a generator.
4. Wind Turbine Blades Act Like Airplane Wings
The blades are designed to generate lift, causing them to spin — similar to how airplane wings create lift in flight.
5. A Single Wind Turbine Can Power Hundreds of Homes
One large wind turbine can produce 2–3 megawatts (MW) — enough to power 500 to 1000 homes per year depending on wind conditions.
6. Wind Energy Is Environmentally Friendly
Wind turbines produce zero air or water pollution, and they help reduce greenhouse gas emissions from fossil fuels.
7. Wind Energy Teaches Multiple Science Concepts
- Physics: Energy conversion, motion, forces, torque
- Environmental Science: Sustainability, clean energy
- Geography: Wind patterns, ideal turbine locations
8. Best Places for Wind Farms
Wind farms are built in open plains, coastal areas, or hilltops — places where wind speed is consistently high.
9. Wind Speed Affects Power Output
Power output is proportional to the cube of the wind speed. Doubling the wind speed increases power output by eight times.
10. Wind Turbines Shut Down in Too Strong Wind
To prevent damage, turbines automatically shut off during extremely high winds (usually above 90 km/h).
