US energy mix shows how the electric grid blends renewables, fossil fuels, nuclear, and hydro, varying by ISO/RTO markets, utilities, and state policies, affecting carbon emissions, pricing, reliability, and access.

 

Key Points

The US energy mix is the grid's source breakdown by region: fossil fuels, renewables, nuclear, and hydro.

✅ Check ISO or RTO dashboards for real-time generation by fuel source.

✅ Utilities may offer green power plans or RECs at modest premiums.

✅ Energy mix shifts with policy, pricing, and grid reliability needs.

 

There are few resources more important than energy. Sure, you may die if you don't eat for days. But your phone will die if you go too long without charging it. Energy feeds tech, the internet, city infrastructure, refrigerators, lights, and has evolved throughout U.S. history in profound ways. You get the idea. Yet unlike our other common needs, such as food, energy sources aren't exactly front of mind for most people. 

"I think a lot of people don't put a lot of bandwidth into thinking about this part of their lives," said Richard McMahon, the SVP of energy supply and finance at Edison Electric Institute, a trade group that represents investor-owned electric companies in the US. 

It makes sense. For most Americans, electricity is always there, and in many locations, there's not much of a choice involved, even as electricity demand is flat across the U.S. today. You sign up with a utility when you move into a new residence and pay your bills when they're due. 

But there's an important reality that indifference eschews: In 2018, a third of the energy-related carbon-dioxide emissions in the US came from the electric power sector, according to the US Energy Information Administration (EIA). 

A good chunk of that is from the residential sector, which consistently uses more energy than commercial customers, per EIA data.

Just as many people exercise choice when they eat, you typically also have a choice when it comes to your energy supply. That's not to say your current offering isn't what you want, or that switching will be easy or affordable, but "if you're a customer and want power with a certain attribute," McMahon said, "you can pretty much get it wherever you are." 

But first, you need to know the energy mix you have right now. As it turns out, it's not so straightforward. At all.

This brief guide may help. 

For some utility providers, you can find out if it publishes the energy mix online. Dominion Energy, which serves Idaho, North Carolina, Ohio, South Carolina, Utah, Virginia, West Virginia, and Wyoming, provides this information in a colored graphic. 

"Once you figure out who your utility is you can figure out what mix of resources they use," said Heidi Ratz, an electricity markets researcher at the World Resources Institute.

But not all utilities publish this information.

It has to do with their role in the grid and reflects utility industry trends in structure and markets. Some utility companies are vertically integrated; they generate power through nuclear plants or wind farms and distribute those electrons directly to their customers. Other utilities just distribute the power that different companies produce. 

Consider Consolidated Edison, or Con Ed, which distributes energy to parts of New York City. While reporting this story, Business Insider could not find information about the utility's energy mix online. When reached for comment, a spokesperson said, "we're indifferent to where it comes from."

That's because, in New York, distribution utilities like Con Ed often buy energy through a wholesale marketplace.

Take a look at this map. If you live in one of the colored regions, your electricity is sold on a wholesale market regulated by an organization called a regional transmission organization (RTO) or independent system operator (ISO). Distribution utilities like Con Ed often buy their energy through these markets, based on availability and cost, while raising questions about future utility revenue models as prices shift. 

Still, it's pretty easy to figure out where your energy comes from. Just look up the ISO or RTO website (such as NYISO or CAISO). Usually, these organizations will provide energy supply information in near-real time. 

That's exactly what Con Edison (which buys energy on the NYISO marketplace) suggested. As of Friday morning, roughly 40% of the energy on the market place was natural gas or other fossil fuels, 34% was nuclear, and about 22% was hydro. 

If you live in another region governed by an ISO or RTO, such as in most of California, you can do the same thing. Like NYISO, CAISO has a dashboard that shows (again, as of Friday morning) about 36% of the energy on the market comes from natural gas and more than 20% comes from renewables. 

In the map linked above, you'll notice that some of the ISOs and RTOs like MISO encompass enormous regions. That means that even if you figure out where the energy in your market comes from, it's not going to be geographically specific. But there are a couple of ways to drill down even further. 

The Environmental Protection Agency has a straightforward tool called Power Profiler. You can enter your zip code to see the fuel mix in your area. But it's not perfect. The data are from 2016 and, in some regions of the country like the upper Midwest, they aren't much more localized, and some import dirty electricity due to regional trading. 

The World Resources Institute also has a tool that allows you to see the electricity mix by state, based on 2017 data from EIA. These numbers represent power generation, not the electricity actually flowing into your sockets, but they offer a rough idea of what energy resources are operating in your state. 

One option is to check with your utility to see if it has a "green power" offering. Over 600 utilities across the country have one, according to the Climate Reality Project, though they often come at a slightly higher cost. It's typically on the scale of just a few more cents per kilowatt-hour. 

There are also independent, consumer-facing companies like Arcadia and Green Mountain Energy that allow you to source renewable energy, by virtually connecting you to community solar projects or purchasing Renewable Energy Certificates, or RECs, on your behalf, as America goes electric and more options emerge. 

"RECs measure an investment in a clean energy resource," Ratz said, in an email. "The goal of putting that resource on the grid is to push out the need for dirtier resources."

The good news: Even if you do nothing, your energy mix will get cleaner. Coal production has fallen to lows not seen since the 1980s, amid disruptions in coal and nuclear sectors that affect reliability and costs, while renewable electricity generation has doubled since 2008. So whether you like it or not, you'll be roped into the clean energy boom one way or another.

Energy freedom and solar’s strategy for the South

South Carolina Energy Freedom Act lifts net metering caps, reforms PURPA, and overhauls utility planning to boost solar competition, grid resiliency, and consumer choice across the Southeast amid Santee Cooper debt and utility monopoly pressure.

 

Key Points

A bipartisan reform lifting net metering caps, modernizing PURPA, and updating utility planning to expand solar.

✅ Lifts net metering cap to accelerate rooftop and community solar.

✅ Reforms PURPA contracts to enable fair pricing and transparent procurement.

✅ Modernizes utility IRP and opens markets to competition and customer choice.

 

The South Carolina House has approved the latest version of the Energy Freedom Act, a bill that overhauls the state’s electricity policies, including lifting the net metering caps and reforming PURPA implementation and utility planning processes in a way that advocates say levels the playing field for solar at all scales.

With Governor Henry McMaster (R) expected to sign the bill shortly, this is a major coup not just for solar in the state, but the region. This is particularly notable given the struggle that solar has had just to gain footing in many parts of the South, which is dominated by powerful utility monopolies and conservative politicians.

Two days ago when the bill passed the Senate we covered the details of the policy, but today we’re going to take a look at the politics of getting the Energy Freedom Act passed, and what this means for other Southern states and “red” states.

 

Opportunity amid crisis

The first thing to note about this bill is that it comes within a crisis in South Carolina’s electricity sector. This was the first legislative session following state-run utility Santee Cooper’s formal abandonment of a project to build two new reactors at the Virgil C. Sumner nuclear power plant, on which work stopped nearly two years ago.

Santee Cooper still holds $4 billion in construction debt related to the nuclear projects. According to an article in The State, this is costing its customers $5 per month toward the current debt, and this will rise to $13 per month for the next 40 years.

Such costs are particularly unwelcome in South Carolina, which has the highest annual electricity bills in the nation due to a combination of very high electricity usage driven by widespread air conditioning during the hot summers and higher prices per unit of power than other Southern states.

Following this fiasco, Santee Cooper’s CEO has stepped down, and the state government is currently considering selling the utility to a private entity. According to Maggie Clark, southeast state affairs senior manager for Solar Energy Industries Association, all of this set the stage for the bill that passed today.

“South Carolina is in a really ripe state for transformational energy policy in the wake of the VC Sumner nuclear plant cancellation,” Clark told pv magazine. “They were looking for a way forward, and I think this bill really provided them something to champion.”

 

Renewable energy policy for red states

This major win for solar policy comes in a state where the Republican Party holds majorities in both houses of the state’s legislature and sends bills to a Republican governor.

Broadly speaking, Republican politicians seldom show the level of interest in supporting renewable energy that Democrats do either at the state or national level, and show even less inclination to act to address greenhouse gas emissions. In fact, the 100% clean energy mandates that are being implemented in four states and Washington D.C. have only passed with Democratic trifectas, in other words with Republicans controlling neither house of the state legislature nor the governor’s office. (Note: This does not apply to Puerto Rico, which has a different party structure to the rest of the United States)

However, South Carolina shows there are Republican politicians who will support pro-renewable energy policies, and circumstances under which Republican majorities will vote for legislation that aids the adoption of solar. And these specific circumstances speak to both different priorities and ideological differences between the two parties.

SEIA’s Maggie Clark emphasizes that the Energy Freedom Act was about reforming market rules. “This was a way to provide a program that did not provide subsidies or incentives in any way, but to really open the market to competition,” explains Clark. “I think that appealing to conservatives in the South about energy independence and resiliency and ultimately cost savings is the winning message on this issue.”

Such messaging in South Carolina is not an accident. Not only has such messaging been successful in the past, but coalition partner Vote Solar paid for polling to find what messages resounded with the state’s voters, and found that choice and competition were likely to resound.

And all of this happened in the context of what Clark describes as an “extremely well-resourced effort”, with SEIA in particular dedicating national attention and resources to the state – as part of an effort by President and CEO Abigail Hopper to shift attention more towards state-level policy. Maggie Clark is one of two new regional staff who Hopper has hired, and SEIA’s first staff member focused on Southern states.

“Absolutely the South is a prioritized region,” Hopper told pv magazine, noting that three Southern states – the Carolinas and Florida – are among the 12 states that the organization has identified to work on this year. “It became clear that as a region it needed more attention.”

SEIA is not expecting fly-by-night victories, and Hopper attributes the success in South Carolina not only to a broad coalition, but to years of work on the ground in the state.

Nor is SEIA the only organization to grow its presence in the region. Vote Solar now has two full time staff located in the South, whereas two years ago its sole staff member dedicated to the region was located in Washington D.C.

 

Ideology versus reality in the South

The Energy Freedom Act aligns with conservative ideas about small government and competition, but the American right is not monolithic, nor do political ideas and actions always line up neatly, as other successful policies in other states in the region show

By far the largest deployment of renewable energy in the nation has been in Texas, aside from in California which leads overall. Here a system of renewable energy zones in the sparsely populated but windy and sunny west, north and center of the state feed cities to the east with power from wind and more recently solar.

This was enabled by transmission lines whose cost was socialized among the state’s ratepayers – a tremendous irony given that the state’s politicians would be some of the last in the nation to want to be identified with socializing anything.

Another example is Louisiana, which saw a healthy residential solar market over the last decade due to a 50% state rebate. The policy has expired, but when operating it was exactly the sort of outright subsidy that right-wing media and politicians rail against.

Of course there is also North Carolina, which built the 2nd-largest solar market in the nation on the back of successful state-level implementation of PURPA, a federal law. Finally there is Virginia, where large-scale projects are booming following a 2018 law that found that 5 GW of solar is in the public interest.

Furthermore, while conservatives continually expound the virtues of the free market, the reality of the electricity sector in the “deep red” South is anything but that. The region missed out on the wave of deregulation in the 1990s, and remains dominated by monopoly utilities regulated by the state: a union of big business and big government where competition is non-existent.

This has also meant that the solar which has been deployed in the South is mostly not the kind of rooftop solar that many think of as embodying energy independence, but rather large-scale solar built in farms, fields and forests.

 

Where to from here?

With such contradictions between stated ideology and practice, it is less clear what makes for successful renewable energy policy in the South. However, opening up markets appears to be working not only in South Carolina, but also in Florida, where third-party solar companies are making inroads after the state’s voters rejected a well-funded and duplicitous utilities’ campaign to kill distributed solar.

SEIA’s Hopper says that she is “aggressively optimistic” about solar in Florida. As utilities have dominated large-solar deployment in the state, even as the state declined federal solar incentives earlier this year, she says that she sees opening up the state’s booming utility-scale solar market to competition as a priority.

Some parts of the region may be harder than others, and it is notable that SEIA has not had as much to say about Alabama, Mississippi or Louisiana, which are largely controlled by utility giants Southern Company and Entergy, or the area under the thumb of the Tennessee Valley Authority, one of the most anti-solar entities in the power sector.

Abby Hopper says ultimately, demand from customers – both individuals and corporations – is the key to transforming policy. “You replicate these victories by customer demand,” Hopper told pv magazine. “That combination of voices from the customer are what’s going to drive change.”

Energy minister unveils Ontario's plan to address growing energy needs

Powering Ontario's Growth accelerates clean electricity, pairing solar, wind, and hydro with energy storage, efficiency investments, and new nuclear, including SMRs, to meet rising demand and net-zero goals while addressing supply planning across the province.

 

Key Points

Ontario's clean energy plan adds renewables, storage, efficiency, and nuclear to meet rising electricity demand.

✅ Over $1B for energy-efficiency programs through 2030+

✅ Largest clean power procurement in Canadian history

✅ Mix of solar, wind, hydro, storage, nuclear, and SMRs

 

Energy Minister Todd Smith has announced a new plan that outlines the actions the government is taking to address the province's growing demand for electricity.

The government is investing over a billion dollars in "energy-efficiency programs" through 2030 and beyond, Smith said in Windsor.

Experts at Ontario's Independent Electricity System recommended the planning start early to meet demand they predict will require the province to be able to generate 88,000 megawatts (MW) in 20 years.

"That means all of our current supply ... would need to double to meet the anticipated demand by 2050," he said during the announcement.

"While we may not need to start building today, government and those in the energy sector need to start planning immediately, so we have new clean, zero emissions projects ready to go when we need them."

The project is called Powering Ontario's Growth and will advance new clean energy generation from a number of sources, including solar, hydroelectric and wind.

He said this would be the biggest acquisition of clean energy in Canada's history.

Smith made the announcement at Hydro One's Keith Transmission Station.

He said the new planned procurement of green power will pair well with recent energy storage procurements, so that power generated by solar panels, for example, can be stored and injected into the system when needed.

NDP Opposition Leader Marit Stiles said Monday's announcement lacks specifics.

"It's light on details, including key questions of cost, climate impact, waste management and financial risk," said Stiles.

"Ford's Conservatives should be playing catch-up after undermining clean energy in their first term. Instead, they're offering generalities and a vague sense of what they might do."

The Green Party criticized the move Monday afternoon, noting that clean, affordable electricity remains a key Ontario election issue today.

"Ontario is facing an energy crunch – and the Ford government is making it worse by choosing more expensive, dirtier options," said MPP for Guelph Mike Schreiner in the statement.

He said Premier Doug Ford has "grossly" mismanaged the province's energy supply by cancelling 750 renewable energy projects and slashing efficiency programs.

"Now, faced with an opportunity to become a leader in a world that's rapidly embracing renewable energy, this government has chosen to funnel taxpayer dollars into polluting fossil gas plants and expensive new nuclear that will take decades to come online," said Schreiner.

Smith announced last week the plan for three more small modular reactors at the site of the Darlington nuclear power plant. The province also shared its intention to add a third nuclear generating station to Bruce Power near Kincardine. 

"With this backwards approach, the Ford government is squandering a once-in-a-generation opportunity to make Ontario a global leader in attracting investment dollars and creating better jobs in the trillion-dollar clean energy sector," said Schreiner.

"Kill the viability": big batteries to lose out from electricity grid rule change

AEMC Storage Charging Rules spark industry backlash as Tesla, Snowy Hydro, and investors warn transmission charges on batteries and pumped hydro could deter grid-scale storage, distort the National Electricity Market, and slow decarbonisation.

 

Key Points

AEMC Storage Charging Rules are proposals to bill grid storage for network use, shaping costs and investment.

✅ Charges apply when batteries draw power; double-charging concerns.

✅ Tesla and Snowy Hydro warn of reduced viability and delays.

✅ AEMO recommends exemptions; investors seek certainty.

 

Tesla, Snowy Hydro and other big suppliers of storage capacity on Australia’s main electricity grid warn proposed rule changes amount to a tax on their operations that will deter investors and slow the decarbonisation of the industry.

The Australian Energy Market Commission (AEMC) will release its final decision this Thursday on new rules for integrating batteries, pumped hydro and other forms of storage.

The AEMC’s draft decision, released in July, angered many firms because it proposed charging storage providers for drawing power, ignoring a recommendation by the Australian Electricity Market Operator (AEMO) that they be exempt.

Battery maker Tesla, which has supplied some of the largest storage to the National Electricity Market, said in a submission that the charges would “kill the commercial viability of all grid storage projects, causing inefficient investment in alternative network”, with consumers paying higher costs.

Snowy Hydro, which is building the giant Snowy 2 pumped storage project and already operates a smaller one, said in its submission the proposed changes if implemented would jeopardise investment.

“This is a major policy change, amounting to a tax on infrastructure critical to achieving a renewable future,” Snowy Hydro said.

AEMO itself argued it was important storage providers were not “disincentivised from connecting to the transmission network, as they generally provide a net benefit to the power system by charging at periods of low demand”.

Australia’s electricity grid faces economic and engineering challenges, similar to Ontario's storage push as it adjusts to the arrival of lower cost and also lower carbon alternatives to fossil fuels.

While rule changes are necessary to account for operators that can both draw from and supply power, how they are implemented can have long-lasting effects on the technologies that get encouraged or repelled, including control of EV charging issues, independent experts say.

“It doesn’t have to be this way,” said Bruce Mountain, director of the Victoria Energy Policy Centre. “In Britain, where the UK grid transformation is underway, the regulator dealing with the same issues has said that storage devices don’t pay the system charges when they withdraw electricity from the grid,” he said.

The prospect that storage operators will have to pay transmission charges could “drastically” affect their profitability since their business models rely on the difference between the price their pay for power and how much they can sell it for. Gas generators and network monopolies would benefit from the change, Mountain said.

An AEMC spokesperson said the commission had consulted widely, including from those who objected to the payment for transmission access.

“The market is moving towards a future that will be increasingly reliant on energy storage to firm up the growing volume of renewable energy and deliver on the increasing need for critical system security services, with examples such as EVs supporting grid stability in California as the ageing fleet of thermal generators retire,” the spokesperson said, declining to elaborate on the final ruling before it is published.

“The regulatory framework needs to facilitate this transition as the energy sector continues to decarbonise,” the official said.

AusNet, which operates the Victorian energy transmission grid, said that while “technological neutrality is paramount for battery and hybrid unit connections to both the distribution and transmission networks,” it did not back charging storage access to networks in all cases.

“[Ausnet] supports a clear exemptions framework for energy storage providers,” a spokesperson said. “We recommend that batteries and other hybrid facilities should have transmission use of system charges waived if they provide a net benefit to network customers.”

We are not aware of anyone that supports the charging storage access to networks in all circumstances.

“Batteries and hybrid facilities that consume energy from the network should be provided no preferential treatment relative to other customers and generators.”

Jonathan Upson, a principal at Strategic Renewable Consulting, though, said the AEMC wants electricity flowing through batteries to be taxed twice to pay network charges – once when the electricity charges the battery and then again when the same electricity is sent out by the battery an hour or two later but this time with customers paying.

“The AEMC’s draft decision has the identical rationale for eliminating franking credits on all dividends, resulting in double taxing of company profits,” he said.

Christiaan Zuur, director of energy transformation at the Clean Energy Council, said that while much of AEMC’s draft proposal was constructive, “those benefits are either nullified or maybe even outweighed” by uncertainty over charges.

“Risk perception” will be important since potential newcomers won’t be sure of what charges they will pay to connect to the grid and existing operators could have their connection agreements reopened, Zuur said.

“Investors focus on the potential risk. It does factor through to the integral costs for projects,” he said.

The outcome of new charges may prompt more people to put batteries on their premises and draw power from their own solar panels, Mountain said, with rising EV adoption introducing new grid challenges, cutting their reliance on a centralised network.

“Ironically, it encourages customers to depend less and less on the grid,” he said. “It’s almost like the capture of the dominant interests playing out over time at their own expense.”

Separately, the latest edition of the Clean Energy Council Confidence Index shows leadership by state governments is helping to shore up investor appetite for investing in renewable energy amid 2021 electricity lessons even with higher 2030 emissions reduction goals from the federal government.

Overall, investor confidence increased by a point in the last six months – from 6.3 to 7.3 out of 10 – following strong commitments and policy development from state governments, particularly on the east coast, the council said.

“The results of this latest survey illustrate the economic value in policy that lowers the emissions footprint of our electricity generation, supporting regional centres and creating jobs. Investors recognise the opportunities created by limiting global temperature rise to 1.5 degrees,” said council chief executive Kane Thornton.

Among the states, NSW, Victoria and Queensland led in terms of positive investor sentiment.

Correction: this article was amended on 30 November. An earlier version stated Ausnet supported charging storage for network access. A spokesperson said it backed a waiver on charges if certain conditions are met.

Hydro One will keep running its U.S. coal plant indefinitely, it tells American regulators

Hydro One-Avista Merger outlines a utility acquisition shaped by Washington regulators, Colstrip coal plant depreciation, and plans for renewables, clean energy, and emissions cuts, while Montana reviews implications for jobs, ratepayers, and a 2027 closure.

 

Key Points

A utility deal setting Colstrip depreciation and renewables, without committing to an early coal plant closure.

✅ Washington sets 2027 depreciation for Colstrip units

✅ Montana reviews jobs, ratepayer impacts, community fund

✅ Avista seeks renewables; no binding shutdown commitment

 

The Washington power company Hydro One is buying will be ready to close its huge coal-fired generating station ahead of schedule, thanks to conditions put on the corporate merger by state regulators there.

Not that we actually plan to do that, the company is telling other regulators in Montana, where coal unit retirements are under debate, the huge coal-fired generating station in question employs hundreds of people. We’ll be in the coal business for a good long time yet.

Hydro One, in which the Ontario government now owns a big minority stake, is still working on its purchase of Avista, a private power utility based in Spokane. The $6.7-billion deal, which Hydro One announced in July, includes a 15 per cent share in two of the four generating units in a coal plant in Colstrip, Montana, one of the biggest in the western United States. Avista gets most of its electricity from hydro dams and gas but uses the Colstrip plant when demand for power is high and water levels at its dams are low.

#google#

Colstrip’s a town of fewer than 2,500 people whose industries are the power plant and the open-pit mines that feed it about 10 million tonnes of coal a year. Two of Colstrip’s generators, older ones Avista doesn’t have any stake in, are closing in 2022. The other two will be all that keep the town in business.

In Washington, they don’t like the coal plant and its pollution. In Montana, the future of Colstrip is a much bigger concern. The companies have to satisfy regulators in both places that letting Hydro One buy Avista is in the public interest.

Ontario proudly closed the last of our coal plants in 2014 and outlawed new ones as environmental menaces, and Alberta's coal phase-out is now slated to finish by 2023. When Hydro One said it was buying Avista, which makes about $100 million in profit a year, Premier Kathleen Wynne said she hoped Ontario’s “value system” would spread to Avista’s operations.

The settlement is “an important step towards bringing together two historic companies,” Hydro One’s chief executive Mayo Schmidt said in announcing it.

The deal has approval from the Washington Utilities and Transportation Commission staff but is subject to a vote by the group’s three commissioners. It doesn’t commit Avista to closing anything at Colstrip or selling its share. But Avista and Hydro One will budget as if the Colstrip coal burners will close in 2027, instead of running into the 2040s as their owners had once planned, a timeline that echoes debates over the San Juan Generating Station in New Mexico.

In accounting terms, they’ll depreciate the value of their share of the plant to zero over the next nine years, reflecting what they say is the end of the plant’s “useful life.” Another of Colstrip’s owners, Puget Sound Energy, has previously agreed with Washington regulators that it’ll budget for a Colstrip closure in 2027 as well.

Avista and Hydro One will look for sources of 50 megawatts of renewable electricity, including independent power projects where feasible, in the next four years and another 90 megawatts to supplement Avista’s supply once the Colstrip plant eventually closes, they promise in Washington. They’ll put $3 million into a “community transition fund” for Colstrip.

The money will come from the companies’ profits and cash, the agreement says. “Hydro One will not seek cost recovery for such funds from ratepayers in Ontario,” it says specifically.

“Ontario has always been a global leader in the transition away from dirty coal power and towards clean energy,” said Doug Howell, an anti-coal campaigner with the Sierra Club, which is a party to the agreement. “This settlement continues that tradition, paving the way for the closure of the largest single source of climate pollution in the American West by 2027, if not earlier.”

Montanans aren’t as thrilled. That state has its own public services commission, doing its own examination of the corporate merger, which has asked Hydro One and Avista to explain in detail why they want to write off the value of the Colstrip burners early. The City of Colstrip has filed a petition saying it wants in on Montana hearings because “the potential closure of (Avista’s units) would be devastating to our community.”

Don’t get too worked up, an Avista vice-president urged the Montana commission just before Easter.

“Just because an asset is depreciated does not mean that one would otherwise remove that asset from service if the asset is still performing as intended,” Jason Thackston testified in a session that dealt only with what the deal with Washington state would mean to Colstrip. We’re talking strictly about an accounting manoeuvre, not an operational commitment.

Six joint owners will have to agree to close the Colstrip generators and there’s “no other tacit understanding or unstated agreement” to do that, he said.

Besides Washington and Montana, state regulators in Idaho, including those overseeing the Idaho Power settlement process, Alaska and Oregon and multiple federal authorities have to sign off on the deal before it can happen. Hydro One hopes it’ll be done in the second half of this year.

Soaring Electricity And Coal Use Are Proving Once Again, Roger Pielke Jr's "Iron Law Of Climate"

Global Electricity Demand Surge underscores rising coal generation, lagging renewables deployment, and escalating emissions, as nations prioritize reliable power; nuclear energy and grid decarbonization emerge as pivotal solutions to the electricity transition.

 

Key Points

A rapid post-lockdown rise in power consumption, outpacing renewables growth and driving higher coal use and emissions.

✅ Coal generation rises faster than wind and solar additions

✅ Emissions increase as economies prioritize reliable baseload power

✅ Nuclear power touted for rapid grid decarbonization

 

By Robert Bryce

As the Covid lockdowns are easing, the global economy is recovering and that recovery is fueling blistering growth in electricity use. The latest data from Ember, the London-based “climate and energy think tank focused on accelerating the global electricity transition,” show that global power demand soared by about 5% in the first half of 2021. That’s faster growth than was happening back in 2018 when electricity use was increasing by about 4% per year.

The numbers from Ember also show that despite lots of talk about the urgent need to reduce greenhouse gas emissions, coal demand for power generation continues to grow and emissions from the electric sector continue to grow: up by 5% over the first half of 2019. In addition, they show that while about half of the growth in electricity demand was met by wind and solar, as low-emissions sources are set to cover almost all new demand over the next three years, overall growth in electricity use is still outstripping the growth in renewables. 

The soaring use of electricity, and increasing emissions from power generation confirm the sage wisdom of Rasheed Wallace, the volatile former power forward with the Detroit Pistons and other NBA teams, and now an assistant coach at the  University of Memphis, who coined the catchphrase: “Ball don’t lie.” If Wallace or one of his teammates was called for a foul during a basketball game that he thought was undeserved, and the opposing player missed the ensuing free throws, Wallace would often holler, “ball don’t lie,” as if the basketball itself was pronouncing judgment on the referee’s errant call. 

I often think about Wallace’s catchphrase while looking at global energy and power trends and substitute my own phrase: numbers don’t lie.

Over the past few weeks Ember, BP, and the International Energy Agency have all published reports which come to the same two conclusions: that countries all around the world — and China's electricity sector in particular — are doing whatever they need to do to get the electricity they need to grow their economies. Second, they are using lots of coal to get that juice. 

As I discuss in my recent book, A Question of Power: Electricity and the Wealth of Nations, Electricity is the world’s most important and fastest-growing form of energy. The Ember data proves that. At a growth rate of 5%, global electricity use will double in about 14 years, and as surging electricity demand is putting power systems under strain around the world, the electricity sector also accounts for the biggest single share of global carbon dioxide emissions: about 25 percent. Thus, if we are to have any hope of cutting global emissions, the electricity sector is pivotal. Further, the soaring use of electricity shows that low-income people and countries around the world are not content to stay in the dark. They want to live high-energy lives with access to all the electronic riches that we take for granted.  

 Ember’s data clearly shows that decarbonizing the global electric grid will require finding a substitute for coal. Indeed, coal use may be plummeting in the U.S. and western Europe, where U.S. electricity consumption has been declining, but over the past two years, several developing countries including Mongolia, China, Bangladesh, Vietnam, Kazakhstan, Pakistan, and India, all boosted their use of coal. This was particularly obvious in China, where, between the first half of 2019 and the first half of 2021, electricity demand jumped by about 14%. Of that increase, coal-fired generation provided roughly twice as much new electricity as wind and solar combined. In Pakistan, electricity demand jumped by about 7%, and coal provided more than three times as much new electricity as nuclear and about three times as much as hydro. (Wind and solar did not grow at all in Pakistan over that period.) 

Hate coal all you like, but its century-long persistence in power generation proves its importance. That persistence proves that climate change concerns are not as important to most consumers and policymakers as reliable electricity. In 2010, Roger Pielke Jr. dubbed this the Iron Law of Climate Policy which says “When policies on emissions reductions collide with policies focused on economic growth, economic growth will win out every time.” Pielke elaborated on that point, saying the Iron Law is a “boundary condition on policy design that is every bit as limiting as is the second law of thermodynamics, and it holds everywhere around the world, in rich and poor countries alike. It says that even if people are willing to bear some costs to reduce emissions (and experience shows that they are), they are willing to go only so far.”

Over the past five years, I’ve written a book about electricity, co-produced a feature-length documentary film about it (Juice: How Electricity Explains the World), and launched a podcast that focuses largely on energy and power. I’m convinced that Pielke’s claim is exactly right and should be extended to electricity and dubbed the Iron Law of Electricity which says, “when forced to choose between dirty electricity and no electricity, people will choose dirty electricity every time.” I saw this at work in electricity-poor places all over the world, including India, Lebanon, and Puerto Rico. 

Pielke, a professor at the University of Colorado as well as a highly regarded author on the politics of climate change and sports governance, has since elaborated on the Iron Law. During an interview in Juice, he explained it thusly: “The Iron Law says we’re not going to reduce emissions by willingly getting poor. Rich people aren't going to want to get poorer, poor people aren't going to want to get poorer.” He continued, “If there is one thing that we can count on it is that policymakers will be rewarded by populations if they make people wealthier. We're doing everything we can to try to get richer as nations, as communities, as individuals. If we want to reduce emissions, we really have only one place to go and that's technology.”

Pielke’s point reminds me of another of my favorite energy analysts, Robert Rapier, who made a salient point in his Forbes column last week. He wrote, “Despite the blistering growth rate of renewables, it’s important to keep in mind that overall global energy consumption is growing. Even though global renewable energy consumption has increased by about 21 exajoules in the past decade, overall energy consumption has increased by 51 exajoules. Increased fossil fuel consumption made up most of this growth, with every category of fossil fuels showing increased consumption over the decade.” 

The punchline here – despite my tangential reference to Rasheed Wallace — is obvious: The claims that massive reductions in global carbon dioxide emissions must happen soon are being mocked by the numbers. Countries around the world are acting in their interest, particularly when it comes to their electricity needs and that is resulting in big increases in emissions. As Ember concludes in their report, wind and solar are growing, and some analyses suggest renewables could eclipse coal by 2025, but the “electricity transition” is “not happening fast enough.”

Ember explains that in the first half of 2021, wind and solar output exceeded the output of the world’s nuclear reactors for the first time. It also noted that over the past two years, “Nuclear generation fell by 2% compared to pre-pandemic levels, as closures at older plants across the OECD, especially amid debates over European nuclear trends, exceeded the new capacity in China.” While that may cheer anti-nuclear activists at groups like Greenpeace and Friends of the Earth, the truth is obvious: the only way – repeat, the only way – the electric sector will achieve significant reductions in carbon dioxide emissions is if we can replace lots of coal-fired generation with nuclear reactors and do so in relatively short order, meaning the next decade or so. Renewables are politically popular and they are growing, but they cannot, will not, be able to match the soaring demand for the electricity that is needed to sustain modern economies and bring developing countries out of the darkness and into modernity. 

Countries like China, Vietnam, India, and others need an alternative to coal for power generation. They need new nuclear reactors that are smaller, safer, and cheaper than the existing designs. And they need it soon. I will be writing about those reactors in future columns.

Ontario Power Generation's Commitment to Small Modular Reactors

OPG Small Modular Reactors advance clean energy with advanced nuclear, baseload power, renewables integration, and grid reliability; factory built, scalable, and cost effective to support Ontario energy security and net zero goals.

 

Key Points

Factory built nuclear units delivering reliable, low carbon power to support Ontario's grid, renewables, climate goals.

✅ Factory built modules cut costs and shorten schedules

✅ Provides baseload power to balance wind and solar

✅ Enhances grid reliability with advanced safety and waste reduction

 

Ontario Power Generation (OPG) is at the forefront of Canada’s energy transformation, demonstrating a robust commitment to sustainable energy solutions. One of the most promising avenues under exploration is the development of Small Modular Reactors (SMRs), as OPG broke ground on the first SMR at Darlington to launch this next phase. These innovative technologies represent a significant leap forward in the quest for reliable, clean, and cost-effective energy generation, aligning with Ontario’s ambitious climate goals and energy security needs.

Understanding Small Modular Reactors

Small Modular Reactors are advanced nuclear power plants that are designed to be smaller in size and capacity compared to traditional nuclear reactors. Typically generating up to 300 megawatts of electricity, SMRs can be constructed in factories and transported to their installation sites, offering flexibility and scalability that larger reactors do not provide. This modular approach reduces construction time and costs, making them an appealing option for meeting energy demands.

One of the key advantages of SMRs is their ability to provide baseload power—energy that is consistently available—while simultaneously supporting intermittent renewable sources like wind and solar. As Ontario continues to increase its reliance on renewables, SMRs could play a crucial role in ensuring that the energy supply remains stable and secure.

OPG’s Initiative

In its commitment to advancing clean energy technologies, OPG has been a strong advocate for the adoption of SMRs. The province of Ontario has announced plans to develop three additional small modular reactors, part of its plans for four Darlington SMRs that would further enhance the region’s energy portfolio. This initiative aligns with both provincial and federal climate objectives, and reflects a collaborative provincial push on nuclear innovation to accelerate clean energy.

The deployment of SMRs in Ontario is particularly strategic, given the province’s existing nuclear infrastructure, including the continued operation of Pickering NGS that supports grid reliability. OPG operates a significant portion of Ontario’s nuclear fleet, and leveraging this existing expertise can facilitate the integration of SMRs into the energy mix. By building on established operational frameworks, OPG can ensure that new reactors are deployed safely and efficiently.

Economic and Environmental Benefits

The introduction of SMRs is expected to bring substantial economic benefits to Ontario. The construction and operation of these reactors will create jobs, including work associated with the Pickering B refurbishment across the province, stimulate local economies, and foster innovation in nuclear technology. Additionally, SMRs have the potential to attract investment from both domestic and international stakeholders, positioning Ontario as a leader in advanced nuclear technology.

From an environmental perspective, SMRs are designed with enhanced safety features and lower waste production compared to traditional reactors, complementing life-extension measures at Pickering that bolster system reliability. They can significantly contribute to Ontario’s goal of achieving net-zero emissions by 2050. By providing a reliable source of clean energy, SMRs will help mitigate the impacts of climate change while supporting the province's transition to a sustainable energy future.

Community Engagement and Collaboration

Recognizing the importance of community acceptance and stakeholder engagement, OPG is committed to an open dialogue with local communities and Indigenous groups. This collaboration is essential to addressing concerns and ensuring that the deployment of SMRs is aligned with the values and priorities of the residents of Ontario. By fostering a transparent process, OPG aims to build trust and support for this innovative energy solution.

Moreover, the development of SMRs will involve partnerships with various stakeholders, including government agencies, research institutions, and private industry, such as the OPG-TVA partnership to advance new nuclear technology. These collaborations will not only enhance the technical aspects of SMR deployment but also ensure that Ontario can capitalize on shared expertise and resources.

Looking Ahead

As Ontario Power Generation moves forward with plans for three additional Small Modular Reactors, the province stands at a critical juncture in its energy evolution. The integration of SMRs into Ontario’s energy landscape promises a sustainable, reliable, and economically viable solution to meet growing energy demands while addressing climate change challenges.

With the support of government initiatives, community collaboration, and continued innovation in nuclear technology, Ontario is poised to become a leader in the advancement of Small Modular Reactors. The successful implementation of these projects could serve as a model for other jurisdictions seeking to transition to cleaner energy sources, highlighting the role of nuclear power in a balanced and sustainable energy future.

In conclusion, OPG's commitment to developing Small Modular Reactors not only reinforces Ontario’s energy security but also demonstrates a proactive approach to addressing the pressing challenges of climate change and environmental sustainability. The future of energy in Ontario looks promising, driven by innovation and a commitment to clean energy solutions.
