In USA, 53% of total electric power is currently generated by coal-fired power plants. Typically, generation of 1 kWh of electricity by a coal-fired power plant produces 966 g of carbon dioxide (CO2). The world's total wind energy capacity is 39,294 MW. Instead wind turbines generate negligible CO2. Determine the amount of CO2 emission per year that is saved by the use of the wind turbines for replacement of coal-fired power plants.
