Solar’s Dirty Secret: Expensive and Unfit for the Grid

To store twelve hours worth of the 1.6 TW total installed global solar power capacity would cost about 12.9 trillion Canadian dollars
Solar energy’s promise of a green, abundant future is captivating—but beneath the shiny panels lies a story of unreliability, hidden costs, and grid instability.
Green enthusiasts endorse solar energy to reduce carbon dioxide (CO2) emissions from traditional energy sources such as coal, oil, and natural gas. The source of solar power, the sun, is free, abundant, and always available somewhere. However, these claims are misleading. Solar energy is costly and unreliable in ways its proponents commonly disguise. If adopted extensively, solar energy will generally make energy and electric power grids more unreliable and expensive.
The solar industry has burgeoned remarkably, with an estimated average compound annual growth rate (CAGR) of about 39 percent from 2021 to 2024. Earlier this century, the growth rate was even faster. As a result, global installed solar capacity has reached 1.6 terawatts (TW), according to the U.S. Energy Department. This capacity is theoretically sufficient to power a billion homes at 1.5 kilowatts per home. However, the term “theoretically” poses a significant challenge. Solar power, without affordable energy storage solutions, is only available during daylight hours.
The minimum amount of storage required to make global solar power truly “dispatchable”—i.e., independent of other backup energy sources—would be twelve hours of storage. Options include batteries, pumped hydro, compressed air, or other technologies. Since batteries are today’s standard method, the following calculation estimates the cost of the minimum amount of battery storage to ensure reliable solar power.
Twelve hours per day multiplied by 1.6 terawatts and dividing the result by one kilowatt-hour (kWh), we arrive at a final requirement of 19.2 billion kWh of storage. According to a meta-study by the National Renewable Energy Lab, the utility-grade cost of battery storage is C$670.99 per kWh.
To store twelve hours worth of the 1.6 TW total installed global solar power capacity would cost about 12.9 trillion Canadian dollars; a safer twenty-four hours’ storage would be double that. Total storage available in 2023 was, the International Energy Agency notes, approximately two hundred and sixty gigawatts (GW) of power – a tiny fraction of power production of 3.2 million GW in 2022, using figures from Statista.
No firms or governments can have the necessary storage to make solar viable even if the entire globe was involved, as the total global GDP was about C$148 trillion in 2023, according to World Bank figures. That is not solar’s only problem. The most harmful effect is how it undermines power grids. The misleading, ‘levelized’ near-zero cost undercuts traditional, reliable on-demand energy sources such as coal, natural gas and nuclear power.
Importantly, high solar and wind power output can make prices turn negative, as an Institute for Energy Research article noted, but can swiftly revert to high prices when winds calm or the sun sets, as the fixed costs of traditional power plants are spread over lower production. Baseload traditional energy sources are essential because the frequent unavailability of renewables can be dangerous. Consequently, overall costs for customers are higher when renewables are included in the energy mix. Solar mandates in California made its power supply wildly erratic.
Without affordable energy storage, solar is a seductive illusion; its unchecked adoption risks turning power grids into unreliable, costly experiments at the expense of energy stability.

Trump’s oil tariffs could spell deficits for Alberta government
From the Fraser Institute
By Tegan Hill
After recently meeting with president-elect Donald Trump, Premier Danielle Smith warned that Trump’s tariffs could include oil. That’s just one more risk factor added to Alberta’s already precarious fiscal situation, which could mean red ink in the near future.
Trump has threatened a 25 per cent tariff on Canadian goods, which includes oil, and could come as early as January 20 when he’s sworn in as president. Such tariffs would likely widen the price differential between U.S. West Texas Intermediate (WTI) crude oil and Alberta’s Western Canadian select (WCS) heavy oil.
In other words, the average price difference between Canadian oil (WCS) and U.S. oil (WTI) could increase, reflecting a larger discount on Canadian oil. According to the Alberta government’s estimate, every $1 that WCS is sold at discount is a $600 million hit to the government’s budget.
To maintain its $4.6 billion projected budget surplus this fiscal year (2024/25), the Smith government is banking on oil prices (WTI) averaging US$74.00 per barrel in 2024/25. But every $1 decline in oil prices leads to a $630 million swing in Alberta’s bottom line. And WTI has dropped as low as US$67.00 per barrel in recent months.
Put simply, Trump’s proposed tariffs would flip Alberta’s budget surplus to a budget deficit, particularly if paired with lower oil prices.
While Smith has been aggressively trying to engage with lawmakers in the United States regarding the tariffs and the inclusion of oil, there’s not much she can do in the short-run to mitigate the effects if Trump’s tariff plan becomes a reality. But the Smith government can still help stabilize Alberta’s finances over the longer term. The key is spending restraint.
For decades, Alberta governments have increased spending when resource revenues were relatively high, as they are today, but do not commensurately reduce spending when resource revenues inevitably decline, which results in periods of persistent budget deficits and debt accumulation. And Albertans already pay approximately $650 each in provincial government debt interest each year.
To its credit, the Smith government has recognized the risk of financing ongoing spending with onetime windfalls in resource revenue and introduced a rule to limit increases in operating spending (e.g. spending on annual items such as government employee compensation) to the rate of population growth and inflation. Unfortunately, the government’s current plan for restraint is starting from a higher base level of spending (compared to its original plan) due to spending increases over the past two years.
Indeed, the government will spend a projected $1,603 more per Albertan (inflation-adjusted) this fiscal year than the Smith government originally planned in its 2022 mid-year budget update. And higher spending means the government has increased its reliance on volatile resource revenue—not reduced it. Put simply, Smith’s plan to grow spending below the rate of inflation and population growth isn’t enough to avoid budget deficits—more work must be done to rein in high spending.
Trump’s tariffs could help plunge Alberta back into deficit. To help stabilize provincial finances over the longer term, the Smith government should focus on what it can control—and that means reining in spending.

Why U.S. tariffs on Canadian energy would cause damage on both sides of the border

More than 450,000 kilometres of pipelines link Canada and the U.S. – enough to circle the Earth 11 times
As U.S. imports of Canadian oil barrel through another new all-time high, leaders on both sides of the border are warning of the threat to energy security should the incoming Trump administration apply tariffs on Canadian oil and gas.
“We would hope any future tariffs would exclude these critical feedstocks and refined products,” Chet Thompson, CEO of the American Fuel & Petrochemical Manufacturers (AFPM), told Politico’s E&E News.
AFPM’s members manufacture everything from gasoline to plastic, dominating a sector with nearly 500 operating refineries and petrochemical plants across the United States.
“American refiners depend on crude oil from Canada and Mexico to produce the affordable, reliable fuels consumers count on every day,” Thompson said.
The United States is now the world’s largest oil producer, but continues to require substantial imports – to the tune of more than six million barrels per day this January, according to the U.S. Energy Information Administration (EIA).
Nearly 70 per cent of that oil came from Canada.
Many U.S. refineries are set up to process “heavy” crude like what comes from Canada and not “light” crude like what basins in the United States produce.
“New tariffs on [Canadian] crude oil, natural gas, refined products, or critical input materials that cannot be sourced domestically…would directly undermine energy affordability and availability for consumers,” the American Petroleum Institute, the industry’s largest trade association, wrote in a recent letter to the United States Trade Representative.
More than 450,000 kilometres of oil and gas pipelines link Canada and the United States – enough to circle the Earth 11 times.
The scale of this vast, interconnected energy system does not exist anywhere else. It’s “a powerful card to play” in increasingly unstable times, researchers with S&P Global said last year.
Twenty-five years from now, the United States will import virtually exactly the same amount of oil as it does today (7.0 million barrels per day in 2050 compared to 6.98 million barrels per day in 2023), according to the EIA’s latest outlook.
“We are interdependent on energy. Americans cutting off Canadian energy would be like cutting off their own arm,” said Heather Exner-Pirot, a special advisor to the Business Council of Canada.
Trump’s threat to apply a 25 per cent tariff on imports from Canada, including energy, would likely “result in lower production in Canada and higher gasoline and energy costs to American consumers while threatening North American energy security,” Canadian Association of Petroleum Producers CEO Lisa Baiton said in a statement.
“We must do everything in our power to protect and preserve this energy partnership.”
Energy products are Canada’s single largest export to the United States, accounting for about a third of total Canadian exports to the U.S., energy analysts Rory Johnston and Joe Calnan noted in a November report for the Canadian Global Affairs Institute.
The impact of applying tariffs to Canadian oil would likely be spread across Canada and the United States, they wrote: higher pump prices for U.S. consumers, weaker business for U.S. refiners and reduced returns for Canadian producers.
“It is vitally important for Canada to underline that it is not just another trade partner, but rather an indispensable part of the economic and security apparatus of the United States,” Johnston and Calnan wrote.
