Benefits of Wind Energy

  • Is a clean, renewable and inexhaustible resource,
  • Reduces reliance on new large hydro power and imported electricity,
  • Benefits the environment and helps fight climate change,
  • Is compatible with mixed land use: forestry, oil and gas, agriculture, and hunting,
  • Creates job opportunities in local areas,
  • Provides a steady income to land-owners and government,
  • Strengthens the tax base, helping to improve services, including schools, police and fire departments.
