- Wind Power
- Advantages
- No pollutants after manufacture
- Takes up little land
- Good for remote areas
- Disadvantages
- Unreliable - doesn't blow constantly and strength is unpredictable
- Low energy density
- Cannot store kinetic energy
- Visual pollution
- Intermittent
- Noise pollution
- Many turbines needed
- Bright lights reflect off blades
- Electromagnetic field causes radio/radar interference
- Kills birds and bats
- Location
- High latitudes
- Few wind fluctuations
- Uplands, open planes, coasts, shallow areas
- Large areas of land
- Horizontal Axis
- Most common
- Must face wind
- Tall tower needed that supports blade weight
- Vertical Axis
- Less advanced technology
- 40%-60% wind power harnessed (good)
- Large blades needed (visual pollution)
- Advantages
