Why Wind is Wrong

By: JC Westling; Claire Anderson

Environmental Impacts

  • 20,000-30,000 birds are killed annually in the U.S. alone
  • Construction destroys underground habitats

Expenses of Wind Energy

Cost of Wind vs. Coal

  • A windmill that produces 4,700,000 kWh of energy annually costs $3-$4 million
  • To produce that much with coal it coasts $812,000
  • Coal is more than 4x cheaper

Side Expenses

  • Set up for a M2 windmill costs around $500,000
  • Spare parts can be from a simple screw, to a new gearbox which can be spendy.

Social Impacts


  • Windmills can produce a peak sound of 105 decibels
  • At a distance they can produce sound at low frequencies that can be bad for the ear

Flying Objects

  • 30,000 - 40,000 birds die annually
  • The windmills produce turbulent pockets of air for three miles behind them

Negative Factors of Wind Energy

  • There's not always wind
  • Gearbox wear out
  • Birds hit the blades
  • The air is very turbulent around them
  • People have disturbed sleep patterns who live by them
