Environmental Benefits of 270 MW Wind Energy Compared to Coal-Fired Generation

In 1998, the Ontario Medical Association declared air pollution a public health crisis in Ontario with coal-fired power plants being major contributors to the smog problem. The Province committed to phasing out coal-fired generation in 2002, and the development of wind energy helped Ontario meet that goal in 2014. Today, wind turbines are harnessing the wind across the Province and generating clean, homegrown energy without producing any harmful emissions and without using water to operate.

Benefits of Wind Energy

  • Is an inexhaustible resource,
  • Reduces reliance on imported fuel,
  • Benefits the environment and helps fight climate change,
  • Is compatible with mixed land use: grazing, agriculture, and hunting,
  • Creates job opportunities in local areas,
  • Provides a steady income to farmers and property-owners,
  • Strengthens the local tax base, helping to improve town services, including schools, police and fire departments,
  • Provides more direct economic impacts than new fossil fuel plants,
  • Produces energy with stable production costs, offering a hedge against other energy sources with volatile fuel markets
