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

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.

IEA peak-oil reversal gives Alberta long-term leverage

The peak-oil narrative has collapsed, and the IEA’s U-turn marks a major strategic win for Alberta
After years of confidently predicting that global oil demand was on the verge of collapsing, the International Energy Agency (IEA) has now reversed course—a stunning retreat that shatters the peak-oil narrative and rewrites the outlook for oil-producing regions such as Alberta.
For years, analysts warned that an oil glut was coming. Suddenly, the tide has turned. The Paris-based IEA, the world’s most influential energy forecasting body, is stepping back from its long-held view that peak oil demand is just around the corner.
The IEA reversal is a strategic boost for Alberta and a political complication for Ottawa, which now has to reconcile its climate commitments with a global outlook that no longer supports a rapid decline in fossil fuel use or the doomsday narrative Ottawa has relied on to advance its climate agenda.
Alberta’s economy remains tied to long-term global demand for reliable, conventional energy. The province produces roughly 80 per cent of Canada’s oil and depends on resource revenues to fund a significant share of its provincial budget. The sector also plays a central role in the national economy, supporting hundreds of thousands of jobs and contributing close to 10 per cent of Canada’s GDP when related industries are included.
That reality stands in sharp contrast to Ottawa. Prime Minister Mark Carney has long championed net-zero timelines, ESG frameworks and tighter climate policy, and has repeatedly signalled that expanding long-term oil production is not part of his economic vision. The new IEA outlook bolsters Alberta’s position far more than it aligns with his government’s preferred direction.
Globally, the shift is even clearer. The IEA’s latest World Energy Outlook, released on Nov. 12, makes the reversal unmistakable. Under existing policies and regulations, global demand for oil and natural gas will continue to rise well past this decade and could keep climbing until 2050. Demand reaches 105 million barrels per day in 2035 and 113 million barrels per day in 2050, up from 100 million barrels per day last year, a direct contradiction of years of claims that the world was on the cusp of phasing out fossil fuels.
A key factor is the slowing pace of electric vehicle adoption, driven by weakening policy support outside China and Europe. The IEA now expects the share of electric vehicles in global car sales to plateau after 2035. In many countries, subsidies are being reduced, purchase incentives are ending and charging-infrastructure goals are slipping. Without coercive policy intervention, electric vehicle adoption will not accelerate fast enough to meaningfully cut oil demand.
The IEA’s own outlook now shows it wasn’t merely off in its forecasts; it repeatedly projected that oil demand was in rapid decline, despite evidence to the contrary. Just last year, IEA executive director Fatih Birol told the Financial Times that we were witnessing “the beginning of the end of the fossil fuel era.” The new outlook directly contradicts that claim.
The political landscape also matters. U.S. President Donald Trump’s return to the White House shifted global expectations. The United States withdrew from the Paris Agreement, reversed Biden-era climate measures and embraced an expansion of domestic oil and gas production. As the world’s largest economy and the IEA’s largest contributor, the U.S. carries significant weight, and other countries, including Canada and the United Kingdom, have taken steps to shore up energy security by keeping existing fossil-fuel capacity online while navigating their longer-term transition plans.
The IEA also warns that the world is likely to miss its goal of limiting temperature increases to 1.5 °C over pre-industrial levels. During the Biden years, the IAE maintained that reaching net-zero by mid-century required ending investment in new oil, gas and coal projects. That stance has now faded. Its updated position concedes that demand will not fall quickly enough to meet those targets.
Investment banks are also adjusting. A Bloomberg report citing Goldman Sachs analysts projects global oil demand could rise to 113 million barrels per day by 2040, compared with 103.5 million barrels per day in 2024, Irina Slav wrote for Oilprice.com. Goldman cites slow progress on net-zero policies, infrastructure challenges for wind and solar and weaker electric vehicle adoption.
“We do not assume major breakthroughs in low-carbon technology,” Sachs’ analysts wrote. “Even for peaking road oil demand, we expect a long plateau after 2030.” That implies a stable, not shrinking, market for oil.
OPEC, long insisting that peak demand is nowhere in sight, feels vindicated. “We hope … we have passed the peak in the misguided notion of ‘peak oil’,” the organization said last Wednesday after the outlook’s release.
Oil is set to remain at the centre of global energy demand for years to come, and for Alberta, Canada’s energy capital, the IEA’s course correction offers renewed certainty in a world that had been prematurely writing off its future.
