prime minister mark carney’s plan to use nuclear power and natural gas to cement canada’s status as a global clean energy superpower should have started a decade ago under justin trudeau.
the question now is whether canada can make that plan a reality at “speeds not seen in generations,” given the 10-year delay in starting it.
based on the lack of action up to now on a policy that should have been obvious from the beginning, the jury is out.
coal-fired electricity is the world’s no. 1 source of greenhouse gas emissions.
nuclear power and natural gas can be used to replace it, ensuring both a safe and reliable source of electricity while dramatically reducing industrial greenhouse gas emissions, because nuclear power is emissions-free while natural gas burns at half the carbon dioxide intensity of coal.
canada is already a global leader in clean electricity — 80% of our generation comes from clean energy sources such as hydro and nuclear power and only 6% from coal — compared to countries such as china, where coal accounts for more than 50% of electricity generation, and 75% in india.
domestically, we already have had a real-world demonstration of how replacing coal-fired electricity with nuclear power and natural gas is feasible.
in 2003, coal-fired electricity was responsible for 25% of all power generation in ontario.
the then liberal provincial government eliminated its use in 11 years — one of the largest and fastest reductions in emissions anywhere in the world — mainly through the use of nuclear power and natural gas.
nuclear power provides base load power to the electricity grid on demand, while natural gas, which can be fired up or shut down quickly, is used to manage the peaks and troughs in daily demand.
alternative energy sources such as wind and solar power are part of ontario’s energy mix, but because they are intermittent — only producing energy when the wind blows and the sun shines — they need to be backed up by natural gas in any event.
