GM to launch Volt by 2010

Ontario Electricity Grid Decarbonization outlines the IESO's net-zero pathway: $400B investment, nuclear expansion, renewables, hydrogen, storage, and demand management to double capacity by 2050 while initiating a 2027 natural gas moratorium.

Key Points

A 2050 plan to double capacity, retire gas, and invest $400B in nuclear, renewables, and storage for a net-zero grid.

✅ $400B over 25 years to meet net-zero electricity by 2050

✅ Capacity doubles to 88,000 MW; demand grows ~2% annually

✅ 2027 gas moratorium; build nuclear, renewables, storage

Ontario will need to spend $400 billion over the next 25 years in order to decarbonize the electricity grid and embrace clean power according to a new report by the province’s electricity system manager that’s now being considered by the Ford government.

The Independent System Electricity Operator (IESO) was tasked with laying out a path to reducing Ontario’s reliance on natural gas for electricity generation and what it would take to decarbonize the entire electricity grid by 2050.

Meeting the goal, the IESO concluded, will require an “aggressive” approach of doubling the electricity capacity in Ontario over the next two-and-a-half decades — from 42,000 MW to 88,000 MW — by investing in nuclear, hydrogen and wind and solar power while implementing conservation policies and managing demand.

“The process of fully eliminating emissions from the grid itself will be a significant and complex undertaking,” IESO president Lesley Gallinger said in a news release.

The road to decarbonization, the IESO said, begins with a moratorium on natural gas power generation starting in 2027 as long as the province has “sufficient, non-emitting supply” to meet the growing demands on the grid.

The approach, however, comes with significant risks.

The IESO said hydroelectric and nuclear facilities can take 10 to 15 years to build and if costs aren’t controlled the plan could drive up the price of clean electricity, turning homeowners and businesses away from electrification.

“Rapidly rising electricity costs could discourage electrification, stifle economic growth or hurt consumers with low incomes,” the report states.

The IESO said the province will need to take several “no regret” actions, including selecting sites and planning to construct new large-scale nuclear plants as well as hydroelectric and energy storage projects and expanding energy-efficiency programs beyond 2024.

Ontario’s minister of energy didn’t immediately commit to implementing the recommendations, citing the need to consult with stakeholders first.

“I look forward to launching a consultation in the new year on next steps from today’s report, including the potential development of major nuclear, hydroelectric and transmissions projects,” Todd Smith said in a statement.

Currently, electricity demand is increasing by roughly two per cent per year, raising concerns Ontario could be short of electricity in the coming years as the manufacturing and transportation sectors electrify and as more sectors consider decarbonization.

At the same time, the province’s energy supply is facing “downward pressure” with the Pickering nuclear power plant slated to wind down operations and the Darlington nuclear generating station under active refurbishment.

To meet the energy need, the Ford government said it intended to extend the life of the Pickering plant until 2026.

But to prepare for the increase, the Ontario government was told the province would also need to build new natural gas facilities to bridge Ontario’s electricity supply gap in the near term — a recommendation the Ford government agreed to.

The IESO said a request for proposals has been opened and the province is looking for host communities, with the expectation that existing facilities would be upgraded before projects on undeveloped land would be considered.

The IESO said the contract for any new facilities would expire in 2040, and all natural gas facilities would be retired in the 2040s.

Ukraine Nuclear Plant Ownership Proposal outlines U.S. management of Ukrainian reactors amid the Russia-Ukraine war, citing nuclear safety, energy security, and IAEA oversight; Kyiv rejects ownership transfer, especially regarding Zaporizhzhia under Russian control.

Key Points

U.S. control of Ukraine's nuclear plants for safety; Kyiv rejects transfer, citing sovereignty risks at Zaporizhzhia.

✅ U.S. proposal to manage Ukraine's reactors amid war

✅ Kyiv refuses ownership transfer; open to investment

✅ Zaporizhzhia under Russian control raises safety risks

In the midst of the ongoing conflict between Russia and Ukraine, U.S. President Donald Trump has proposed a controversial idea: Ukraine should give its nuclear power plants to the United States for safekeeping and management. This suggestion came during a phone call with Ukrainian President Volodymyr Zelenskyy, wherein Trump expressed the belief that American ownership of these nuclear plants could offer them the best protection amid the ongoing war. But Kyiv, while open to foreign support, has firmly rejected the idea of transferring ownership, especially as the Zaporizhzhia nuclear plant remains under Russian occupation.

Ukraine’s nuclear energy infrastructure has always been a vital component of its power generation. Before the war, the country’s four nuclear plants supplied nearly half of its electricity. As Russia's military forces target Ukraine's energy infrastructure, including power plants and coal mines, international watchdogs like the IAEA have warned of nuclear risks as these nuclear facilities have become crucial to maintaining the nation’s energy stability. The Zaporizhzhia plant, in particular, has attracted international concern due to its size and the ongoing threat of a potential nuclear disaster.

Trump’s Proposal and Ukraine’s Response

Trump’s proposal of U.S. ownership came as a response to the ongoing threats posed by Russia’s occupation of the Zaporizhzhia plant. Trump argued that the U.S., with its expertise in running nuclear power plants, could safeguard these facilities from further damage and potential nuclear accidents. However, Zelenskyy quickly clarified that the discussion was only focused on the Zaporizhzhia plant, which is currently under Russian control. The Ukrainian president emphasized that Kyiv would not entertain the idea of permanently transferring ownership of its nuclear plants, even though they would welcome investment in their restoration and modernization, particularly after the war.

The Zaporizhzhia nuclear plant has been a focal point of geopolitical tensions since Russia's occupation in 2022. Despite being in "cold shutdown" to prevent further risk of explosions, the facility remains a major concern due to its potential to cause a nuclear disaster. Ukrainian officials, along with international observers, have raised alarm about the safety risks posed by the plant, including mines at Zaporizhzhia reported by UN watchdogs, which is situated in a war zone and under the control of Russian forces who are reportedly neglecting proper safety protocols.

The Fear of a Nuclear Provocation

Ukrainians have expressed concerns that Trump’s proposal could embolden Russia to escalate tensions further, even as a potential agreement on power-plant attacks has been discussed by some parties. Some fear that any attempt to reclaim the plant by Ukraine could trigger a Russian provocation, including a deliberate attack on the plant, which would have catastrophic consequences for both Ukraine and the broader region. The analogy is drawn with the destruction of the Nova Kakhovka dam, which Ukraine accuses Russia of sabotaging, an act that severely disrupted water supplies to the Zaporizhzhia plant. Ukrainian military officials, including Ihor Romanenko, a former deputy head of Ukraine’s armed forces, warned that Trump’s suggestion might be an exploitation of Ukraine’s vulnerable position in the ongoing war.

Despite these fears, there are some voices within Ukraine, including former employees of the Zaporizhzhia plant, who believe that a deliberate attack by Russian forces is unlikely. They argue that the Russian military needs the plant in functioning condition for future negotiations, with Russia building new power lines to reactivate the site as part of that calculus, and any damage could reduce its value in such exchanges. However, the possibility of Russian negligence or mismanagement remains a significant risk.

The Strategic Role of Ukraine's Nuclear Plants

Ukraine's nuclear plants were a cornerstone of the country’s energy sector long before the conflict began. In recent years, as Ukraine lost access to coal resources in the Donbas region due to Russian occupation, nuclear power became even more vital, alongside a growing focus on wind power to improve resilience. The country’s reliance on these plants grew as Russia launched a sustained campaign to destroy Ukraine’s energy infrastructure, including attacks on nuclear power stations.

The Zaporizhzhia plant, in particular, holds strategic importance not only due to its size but also because of its location in southeastern Ukraine, an area that has been at the heart of the conflict. Despite being in Russian hands, the plant’s reactors have been safely shut down, reducing the immediate risk of a nuclear explosion. However, the plant’s future remains uncertain, as Russia’s long-term control over it could disrupt Ukraine’s energy security for years to come.

Wider Concerns About Aging Nuclear Infrastructure

Beyond the geopolitical tensions, there are broader concerns about the aging infrastructure of Ukraine's nuclear power plants. International watchdogs, including the environmentalist group Bankwatch, have criticized these facilities as “zombie reactors” due to their outdated designs and safety risks. Experts have called for Ukraine to decommission some of these reactors, fearing that they are increasingly unsafe, especially in the context of a war.

However, Ukrainian officials, including Petro Kotin, head of Energoatom (Ukraine's state-owned nuclear energy company), argue that these reactors are still functional and critical to Ukraine's energy needs. The ongoing conflict, however, complicates efforts to modernize and secure these facilities, which are increasingly vulnerable to both physical damage and potential nuclear hazards.

The Global Implications

Trump's suggestion to take control of Ukraine's nuclear power plants has raised significant concerns on the international stage. Some fear that such a move could set a dangerous precedent for nuclear security and sovereignty. Others see it as an opportunistic proposal that exploits Ukraine's wartime vulnerability.

While the future of Ukraine's nuclear plants remains uncertain, one thing is clear: these facilities are now at the center of a geopolitical struggle that could have far-reaching consequences for the energy security of Europe and the world. The safety of these plants and their role in Ukraine's energy future will remain a critical issue as the war continues and as Ukraine navigates its relations with both the U.S. and Russia, with the grid even having resumed electricity exports at times.

Polycrystalline Tin Selenide Thermoelectrics enable waste heat recovery with ZT 3.1, matching single crystals while cutting costs, powering greener car engines, industrial furnaces, and thermoelectric generators via p-type and emerging n-type designs.

Key Points

Low-cost tin selenide devices that turn waste heat into power, achieving ZT 3.1 and enabling p-type and n-type modules.

✅ Oxygen removal prevents heat-leaking tin oxide grain skins.

✅ Polycrystalline ingots match single-crystal ZT 3.1 at lower cost.

✅ N-type tin selenide in development to pair with p-type.

So-called thermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, providing what seems like a free lunch. But despite helping power the Mars rovers, the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermoelectrics that work just as well as the pricey kind. The work could pave the way for a new generation of greener car engines, industrial furnaces, and other energy-generating devices.

“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist at Beihang University who was not involved with the work. He notes there are still a few more steps to take before these materials can become high-performing thermoelectric generators. However, he says, “I think this will be used in the not too far future.”

Thermoelectrics are semiconductor devices placed on a hot surface, like a gas-powered car engine or on heat-generating electronics using thin-film converters to capture waste heat. That gives them a hot side and a cool side, away from the hot surface. They work by using the heat to push electrical charges from one to the other, a process of turning thermal energy into electricity that depends on the temperature gradient. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.

 Over the past 2 decades, researchers have produced thermoelectric materials with increasing ZTs, while related advances such as nighttime solar cells have broadened thermal-to-electric concepts. The record came in 2014 when Mercouri Kanatzidis, a materials scientist at Northwestern University, and his colleagues came up with a single crystal of tin selenide with a ZT of 3.1. Yet the material was difficult to make and too fragile to work with. “For practical applications, it’s a non-starter,” Kanatzidis says.

So, his team decided to make its thermoelectrics from readily available tin and selenium powders, an approach that, once processed, makes grains of polycrystalline tin selenide instead of the single crystals. The polycrystalline grains are cheap and can be heated and compressed into ingots that are 3 to 5 centimeters long, which can be made into devices. The polycrystalline ingots are also more robust, and Kanatzidis expected the boundaries between the individual grains to slow the passage of heat. But when his team tested the polycrystalline materials, the thermal conductivity shot up, dropping their ZT scores as low as 1.2.

In 2016, the Northwestern team discovered the source of the problem: an ultrathin skin of tin oxide was forming around individual grains of polycrystalline tin selenide before they were pressed into ingots. And that skin acted as an express lane for the heat to travel from grain to grain through the material. So, in their current study, Kanatzidis and his colleagues came up with a way to use heat to drive any oxygen away from the powdery precursors, leaving pristine polycrystalline tin selenide, whereas other devices can generate electricity from thin air using ambient moisture.

The result, which they report today in Nature Materials, was not only a thermal conductivity below that of single-crystal tin selenide but also a ZT of 3.1, a development that echoes nighttime renewable devices showing electricity from cold conditions. “This opens the door for new devices to be built from polycrystalline tin selenide pellets and their applications to be explored,” Kanatzidis says.

Getting through that door will still take some time. The polycrystalline tin selenide the team makes is spiked with sodium atoms, creating what is known as a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.

Zhao’s team recently reported making an n-type single-crystal tin selenide by spiking it with bromine atoms. And Kanatzidis says his team is now working on making an n-type polycrystalline version. Once n-type and p-type tin selenide devices are paired, researchers should have a clear path to making a new generation of ultra-efficient thermoelectric generators. Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial furnaces to scavenge energy from some of the 65% of fossil fuel energy that winds up as waste heat.

Minnesota 100% Carbon-Free Electricity advances renewable energy: wind, solar, hydropower, hydrogen, biogas from landfill gas and anaerobic digestion; excludes incineration in environmental justice areas; uses renewable energy credits and streamlined permitting.

Key Points

Minnesota's mandate requires utilities to deliver 100% carbon-free power by 2040 with targets and EJ safeguards.

✅ Utilities must hit 90% carbon-free by 2035; 100% by 2040.

✅ Incineration in EJ areas excluded; biogas, wind, solar allowed.

✅ Compliance via renewable credits; streamlined permitting.

Minnesota Gov. Tim Walz, D, is expected to soon sign a bill establishing a clean electricity standard requiring utilities in the state to provide electricity from 100% carbon-free sources by 2040. The bill also calls for utilities to generate at least 55% of their electricity from renewable energy sources by 2035, a trajectory similar to New Mexico's clean electricity push underway this decade.

Electricity generated from landfill gas and anaerobic digestion are named as approved renewable energy technologies, but electricity generated from incinerators operating in “environmental justice areas”, reflecting concerns about renewable facilities violating pollution rules in some states, will not be counted toward the goal. Wind, solar, and certain hydropower and hydrogen energy sources are also considered renewable in the bill. 

The bill defines EJ areas as places where at least 40% of residents are not white, 35% of households have an income that’s below 200% of the federal poverty line, and 40% or more of residents over age 5 have “limited” English proficiency. Areas the U.S. state defines as “Indian country” are also considered EJ areas.

Some of the state’s largest electric utilities, like Xcel Energy and Minnesota Power, have already pledged to move to carbon-free energy, and utilities such as Alliant Energy have outlined carbon-neutral plans in the region, but this bill speeds up that goal by 10 years, Minnesota Public Radio reported. The bill calls for public utilities operating in the state to be 80% carbon-free and other electric utilities to be 60% carbon-free by 2030. All utilities must be 90% carbon-free by 2035 before ultimately hitting the 100% mark in 2040, according to the bill.  

The bill gives utilities some leniency if they demonstrate to state regulators that they can’t offer affordable power while working toward the benchmarks, acknowledging reliability challenges seen in places like California's grid during the clean energy transition. It also allows utilities to buy renewable energy credits to meet the standard instead of generating the energy themselves. 

Patrick Serfass, executive director of the American Biogas Council, said the bill will incentivize more biogas-related electricity projects, “which means the recycling of more organic material and more renewable electricity in the state. Those are all good things,” he said. ABC sees significant potential for biogas production in Minnesota, though the federal climate law has delivered mixed results for accelerating clean power deployment.

The bill also aims to streamline the permitting process for new energy projects in the state, even as some states consider limits on clean energy that would constrain utility use, and calls for higher minimum wage requirements for workers.

Alberta Electricity Price Hikes spotlight grid reliability, renewable transition, coal phase-out, and energy poverty, as policy shifts and investor reports warn of rate increases, biomass trade-offs, and sustainability challenges impacting households and businesses.

Key Points

Projected power bill hikes from market reforms, renewables, coal phase-out, and reliability costs in Alberta.

✅ Investor report projects 3x-7x bills and $50B market transition costs

✅ Policy missteps cited in Ontario, Germany, Australia price spikes

✅ Debate: retain coal vs. speed renewables, storage, and grid upgrades

Since when did electricity become a scarce resource?

I thought all the talk about greening the grid was about having renewable, sustainable, less polluting options to fulfill our growing need for power. Yet, increasingly, we are faced with news stories that indicate using power is bad in and of itself, even as flat electricity demand worries utilities.

The implication, I guess, is that we should be using less of it. But, I don’t want to use less electricity. I want to be able to watch TV, turn my lights on when the sun sets at 4 p.m. in the winter, keep my food cold and power my devices.

We once had a consensus that a reliable supply of power was essential to a growing economy and a high quality of life, a point underscored by brownout risks in U.S. markets.

I’m beginning to wonder if we still have that consensus.

And more importantly, if our decision makers have determined electricity is a vice as opposed to an essential of life – as debates over Alberta electricity policy suggest – you know what is going to happen next. Prices are going to rise, forcing all of us to use less.

How much would it hurt your bottom line if your electricity bill went up three-fold? How about seven-fold? That is the grim picture that Todd Beasley painted for us on Tuesday’s show.

Last week, he launched a campaign on behalf of Albertans for Sustainable Electricity, called Stop the Shock. He shared the results of an internal investor report that concluded Alberta’s power market overhaul would cost an estimated $50 billion to implement and could result in a three to seven-fold increase in electricity bills.

Now, my typical power bill averages $70 a month. That would be like having it grow to $210 a month, or just over $2,500 a year. If it’s a seven-fold increase that would be more like $5,000 a year. That may be manageable for some families, but I can think of a lot of things I’d rather do with $5,000 than pay more to keep my fridge running so my food doesn’t spoil.

For low-income families that would be a real hardship.

Beasley said Ontario’s inept handling of its electricity market and the phase-out of coal power resulted in price spikes that left more than 70,000 individuals facing energy poverty.

Germany and Australia realized they made the same mistake and are returning some electricity to coal.

Beasley shared a long list of Canadian firms – including our own Canadian Pension Plan – that are investing in coal development around the world. Meanwhile, Canadian governments remain in a mad rush to phase it out here. That’s not the only hypocrisy.

Rupert Darwall, author of Green Tyranny: Exposing the Totalitarian Roots of the Climate Industrial Complex, revealed in a recent column what he calls “the scandal at the heart of the EU’s renewable policies.”

Turns out most of their expansion in renewable energy has come from biomass in the form of wood. Not only does burning wood produce more CO2, it also eliminates carbon sinks.

To meet the EU’s 2030 target would require cutting down trees equivalent to the combined harvest in Canada and the United States. As he puts it, “Whichever way you look at it, burning the world’s carbon sinks to meet the EU’s arbitrary renewable energy targets is environmentally insane.”

Beasley’s group is trying to bring some sanity back to the discussion. The goal should be to move to a greener grid while maintaining abundant, reliable and cheap power, and examples like Texas grid improvements show practical steps. He thinks to achieve all these goals, coal should remain part of the mix. What do you think?

Costa Rica Renewable Energy Record highlights 99.99% clean power in May 2019, driven by hydropower, wind, solar, geothermal, and biomass, enabling ICE REM electricity exports and reduced rates from optimized generation totaling 984.19 GWh.

Key Points

May 2019 benchmark: Costa Rica generated 99.99% of 984.19 GWh from renewables, shifting from imports to regional exports.

✅ 99.99% renewable share across hydro, wind, solar, geothermal, biomass

✅ 984.19 GWh generated; ICE suspended imports and exported via REM

✅ Geothermal output increased to offset dry-season hydropower variability

During the whole month of May 2019, Costa Rica generated a total of 984.19 gigawatt hours of electricity, the highest in the country’s history. What makes this feat even more impressive is the fact that 99.99% of this energy came from a portfolio of renewable sources such as hydropower, wind, biomass, solar, and geothermal.

With such a high generation rate, the state power company Instituto Costariccense de Electricidad (ICE) were able to suspend energy imports from the first week of May and shifted to exports, while U.S. renewable electricity surpassed coal in 2022 domestically. To date, the power company continues to sell electricity to the Regional Electricity Market (REM) which generates revenues and is likely to reduce local electricity rates, a trend echoed in places like Idaho where a vast majority of electricity comes from renewables.

The record-breaking power generation was made possible by optimization of the country’s renewable sources, much as U.S. wind capacity surpassed hydro capacity at the end of 2016 to reshape portfolios. As the period coincided with the tail end of the dry season, the geothermal quota had to be increased.

Costa Rica remains a leader in renewable power generation, whereas U.S. wind generation has become the most-used renewable source in recent years. In 2015, more than 98% of the country’s electrical generation came from renewable sources, while U.S. renewables hit a record 28% in April in one recent benchmark. Through the years, this figure has remained fairly constant despite dry bouts caused by the El Niño phenomenon, and U.S. solar generation also continued to rise.
