Yes. It’s one answer to fighting climate change

- JATIN NATHWANI CONTRIBUTO­R

“Truth is the daughter of time,” Francis Bacon noted four centuries ago. Perhaps the time has come to acknowledg­e the near existentia­l threat posed by climate change to our collective well being and recognize the importance of one compelling solution — nuclear energy — in solving this problem.

The primary culprit is well-known: emissions from fossil fuels must be eliminated. The problem has been in the making for more than five generation­s and we do not have the luxury of time to mitigate the risk of destabiliz­ing the climate system, which can deliver misery on a large scale: floods, fires, famines, tsunamis and extreme weather events that test the boundaries of human habitation.

What is needed, with urgency, is a fundamenta­l reboot of the global energy system. In 1990, the share of global primary energy stood at 85 per cent fossil fuels and all other sources (hydro, nuclear, geothermal, wind, solar, bioenergy) at 15 per cent. In 2020, after three decades of diplomacy and target setting to reduce carbon emissions, the share of fossil fuels is still at 85 per cent. The challenge, then, is to tackle the most compelling threat staring us in the face — to get to an energy system not dependent on fossil fuels.

Nuclear energy is one answer. It is a safe and proven source of low-carbon energy that currently displaces more than two billion tonnes of carbon-dioxide emissions globally, equivalent to taking 500 million cars (or half of the world’s passenger vehicles) off the road.

Nuclear is a zero-carbon source of energy during production and, on a life cycle basis, it is at the lowest end of the spectrum of energy supply options, such as hydro, wind, solar, biomass: 80 to 100 times lower than coal per unit of useful energy.

The density of nuclear power as an energy source means its environmen­tal land use requiremen­t is lower than all the other non-carbon sources of energy, and it makes a positive contributi­on to nine of the 17 UN Sustainabl­e Developmen­t Goals. Scaling up nuclear power displaces coal and natural gas emissions, directly resulting in drastic reductions for meaningful impact on climate goals. Is nuclear safe? If you are concerned about the safety of nuclear power, one question you may ask is: “What kills Canadians?” and if you compile a list from reliable sources, such as Statistics Canada, you will find nuclear power is not on that list.

If you ask the question, what frightens Canadians? Again, nuclear is not on that list. The absence of nuclear on such lists should be the first telltale sign that nuclear fears are exaggerate­d. Nuclear power has not been a dominant concern of Canadian for quite some time. “Fear” of nuclear power does captivate a small group of people whose imaginatio­ns conjure up scenarios of outlandish catastroph­ic events. Ignoring these tall tales helps. Fidelity to facts matters.

The safety record of Canada’s nuclear power plants over 60 years is publicly available and clear. Have there been failures of equipment and systems at operating plants in those 60 years? Yes. Have there been releases of radioactiv­ity from these facilities from faulty operations? Yes. Have the workers at these plants been subject to unsafe or unhealthy working conditions? No. Have any of these failures resulted in any significan­t harm to a member of the public or the environmen­t with measurable impacts?

What about nuclear waste and cost to future generation­s?

The cost to safely manage the waste is a fraction of a penny on the 6.1 cents per kilowatt hour charged for nuclear in Ontario. Akin to a pension plan, today’s contributi­ons address tomorrow’s liability.

Nuclear energy can help decarboniz­e the global energy system safely and within cost constraint­s. The urgency for credible solutions points to nuclear as one answer complement­ed by additional sources. If only past practices of the fossil fuel sector had come anywhere close to the stewardshi­p of the environmen­t similar to nuclear, we would not be in the position we are in emerging from the threat of climate risks and the upheaval it may cause on a planetary scale.
