From the Fraser Institute

By Kenneth P. Green

After accounting for backup, energy storage and associated indirect costs—estimated solar power costs skyrocket from US$36 per megawatt hour (MWh) to as high as US$1,548, and wind generation costs increase from US$40 to up to US$504 per MWh.

At a recent energy conference in Houston, U.S. Energy Secretary Chris Wright said the Trump administration will end the Biden administration’s “irrational, quasi-religious policies on climate change that imposed endless sacrifices on our citizens.” He added that “Natural gas is responsible for 43 per cent of U.S. electricity production,” and beyond the obvious scale and cost problems, there’s “simply no physical way that wind, solar and batteries could replace the myriad uses of natural gas.”

In other words, as a federal election looms, once again the United States is diverging from Canada when it comes to energy policy.

Indeed, wind power is particularly unattractive to Wright because of its “incredibly high prices,” “incredibly huge investment” and “large footprint on the local communities,” which make it unattractive to people living nearby. Globally, Wright observes, “Natural gas currently supplies 25 per cent of raw energy globally, before it is converted into electricity or some other use. Wind and solar only supply about 3 per cent.”

And he’s right. Renewables are likely unable, physically or economically, to replace natural gas power production to meet current or future needs for affordable, abundant and reliable energy.

In a recent study published by the Fraser Institute, for example, we observed that meeting Canada’s predicted electricity demand through 2050 using only wind power (with natural gas discouraged under current Canadian climate policies) would require the construction of approximately 575 wind-power installations, each the size of Quebec’s Seigneurie de Beaupré wind farm, over 25 years. However, with a construction timeline of two years per project, this would equate to 1,150 construction years. This would also require more than one million hectares of land—an area nearly 14.5 times the size of Calgary.

Solar power did not fare much better. According to the study, to meet Canada’s predicted electricity demand through 2050 with solar-power generation would require the construction of 840 solar-power generation stations the size of Alberta’s Travers Solar Project. At a two-year construction time per facility, this adds up to 1,680 construction years to accomplish.

And at what cost? While proponents often claim that wind and solar sources are cheaper than fossil fuels, they ignore the costs of maintaining backup power to counter the unreliability of wind and solar power generation. A recent study published in Energy, a peer-reviewed energy and engineering journal, found that—after accounting for backup, energy storage and associated indirect costs—estimated solar power costs skyrocket from US$36 per megawatt hour (MWh) to as high as US$1,548, and wind generation costs increase from US$40 to up to US$504 per MWh.

The outlook for Canada’s switch to renewables is also dire. TD Bank estimated that replacing existing gas generators with renewables (such as solar and wind) in Ontario could increase average electricity costs by 20 per cent by 2035 (compared to 2021 costs). In Alberta, electricity prices would increase by up to 66 per cent by 2035 compared to a scenario without changes.

Under Canada’s current greenhouse gas (GHG) regulatory regime, natural gas is heavily disfavoured as a potential fuel for electricity production. The Trudeau government’s Clean Electricity Regulations (CER) would begin curtailing the use of natural gas beginning in 2035, leading largely to a cessation of natural gas power generation by 2050. Under CER and Ottawa’s “net-zero 2050” GHG emission framework, Canada will be wedded to a quixotic mission to displace affordable reliable natural gas power-generation with expensive unreliable renewables that are likely unable to meet expected future electricity demand.

With a federal election looming, Canada’s policymakers should pay attention to new U.S. energy policy on natural gas, and pull back from our headlong rush into renewable power. To avoid calamity, the next federal government should scrap the Trudeau-era CER and reconsider the entire “net-zero 2050” agenda.
