Ontario Getting Out of Coal-fired Generation

Celsias

 

Not often we hear good news in the clean energy sector from Canada so we are pleased to see that Ontario will shut the last of its coal plants in southern Ontario by the end of 2013, a year ahead of schedule. 

coal According to a 2005 independent study, "Cost Benefit Analysis: Replacing Ontario's Coal-Fired Electricity Generation," this will save approximately $4.4 billion annually when health and environmental costs are taken into consideration.

The closure of coal plants has already produced significant health and environmental benefits for Ontarians. For example, 2011 sulphur dioxide and nitrogen oxides emissions were 93 per cent and 85 per cent lower, respectively, than they were in 2003.  And in 2011, Ontario's coal plants emitted 43 kilograms of mercury, the lowest on record in over 45 years.

The Ministry of Energy reports it has  already shut down 11 of 19 coal units. By theontario wind end of 2013 we will have shut down 17 out of 19. Ontario's electricity sector greenhouse gas emissions will decrease dramatically as a result of becoming coal-free, from a high of 41.4 megatonnes in 2000 to  five megatonnes post-2020.

In 2003, coal accounted for 25 per cent of our generation. Coal-fired generation made up less than three per cent of Ontario's total electricity generation in 2011.

Ontario is replacing coal with a mix of emission-free energy sources like nuclear and renewables, along with lower-emission energy sources like natural gas. Natural gas emits nearly 70 per cent less particulate matter than coal and virtually eliminates mercury and sulphur dioxide emissions. In 2011 over 80 per cent of our electricity generated was emissions-free.

If you see any unhelpful comments, please let us know immediately.

At least they were honest - yes, reducing coal - which is great - but replaced by 'emission free' nuclear and 'lower-emission' gas.
Ontario produces most of its energy using nuclear (about 60%) and nuclear is expanding.

and the lobby against wind-generated power is strong, especially in rural communities
