CanadaÂ’s former nuclear watchdog is seeking a judicial review into her firing by the Conservative government resulting from the shutdown of a nuclear research reactor.

Linda Keen, a long-time bureaucrat, had angered Prime Minister Stephen Harper with her handling of the Chalk River reactor shutdown that left the Conservative government scrambling and embarrassed as it coped with the shortage of medical isotopes.

The motion, submitted to the Federal Court, is the latest development in the bitter dispute between Keen and the Conservatives. She was fired as president of the Canadian Nuclear Safety Commission (CNSC) when she wouldnÂ’t okay the start-up of the aging Chalk River reactor.

“By this application for judicial review, Ms. Keen is asking the Federal Court to declare that she was unlawfully removed as president and that the November 2005 Order in Council, which reappointed her as president, remains in full force and effect,” said Ottawa lawyer Allan O’Brien.

Keen, who remains on the CNSC board, recently told ParliamentÂ’s natural resources committee that it is not the job of a nuclear regulator to ensure the production of isotopes but rather that the public is protected from nuclear accidents.

The reactor was voluntarily taken out of service by Atomic Energy Canada Ltd. because of ongoing safety concerns.

The Harper government brought in emergency legislation to override KeenÂ’s safety warnings and restart the reactor in mid-December. The CNSC is an independent quasi-judicial body meant to work at armÂ’s length from the government.

It was a month later that Natural Resources Minister Gary Lunn told Keen that the government had lost confidence in her, but when he appeared before the committee he could not cite one reason for the decision to dump Keen, who was to serve as president until 2010.

The Chalk River reactor, run by Atomic Energy of Canada Ltd., was shut down on Nov. 18 for routine maintenance, but an inspection by the regulatory staff found that mandatory safety upgrades – connecting vital cooling pumps to an emergency power supply that would work even if the area was hit with an earthquake – had not been done.

$550 Million in Clean Energy Funding to Benefit More than 250 Million Americans

EECBG Program Funding empowers states, Tribes, and local governments with DOE grants to deploy clean energy, energy efficiency, EV infrastructure, and community solar, cutting emissions, lowering utility bills, and advancing net-zero decarbonization.

 

Key Points

EECBG Program Funding is a $550M DOE grant for states, Tribes, and governments to deploy clean energy and efficiency.

✅ Supports EV infrastructure and community solar deployment

✅ Cuts emissions and lowers utility costs via efficiency

✅ Prioritizes Justice40 benefits for underserved communities

 

The Biden-Harris Administration, through the U.S. Department of Energy (DOE), today released a Notice of Intent announcing $550 million to support community-based clean energy in state, Tribal, and local governments — serving more than 250 million Americans. This investment in American communities, through the Energy Efficiency and Conservation Block Grant (EECBG) Program, will support communities across the country to develop local programming and deploy clean energy technologies to cut emissions, advance a 90% carbon-free electricity goal nationwide, and reduce consumers’ energy costs, and help meet President Biden’s goal of a net-zero economy by 2050. 

“This funding is a streamlined and flexible tool for local governments to build their electricity future with clean energy,” said U.S. Secretary of Energy Jennifer M. Granholm. “State, local, and Tribal communities nationwide will be able to leverage this funding to drive greater energy efficiency and conservation practices to lower utility bills and create healthier environments for American families.”   

The EECBG Program will fund 50 states, five U.S. territories, the District of Columbia, 774 Tribes, and 1,878 local governments in a variety of capacity-building, planning, and infrastructure efforts to reduce carbon emissions and energy use and improve energy efficiency in the transportation, building, and other related sectors. For example, communities with this funding can build out electric vehicle infrastructure and deploy community solar to serve areas that otherwise do not have access to electric vehicles or clean energy, particularly through a rural energy security program where appropriate.  

The $550 million made available through the Bipartisan Infrastructure Law (BIL) represents the second time that the EECBG Program has been funded, the first of which was through the American Recovery and Reinvestment Act of 2009. With this most recent funding, communities can build on prior investments and leverage additional clean energy funding from DOE, other federal agencies, and the private sector to achieve sustained impacts, supported by a Clean Electricity Standard where applicable, that can put their communities on a pathway to decarbonization. 

Through the EECBG Program and the Office of State and Community Energy Programs (SCEP), DOE will support the many diverse state, local, and tribal communities across the U.S., including efforts to revitalize coal communities through clean energy, as they implement this funding and other clean energy projects. To ensure no communities are left behind, the program aligns with President’s Justice40 initiative and efforts toward equity in electricity regulation to help ensure that 40% of the overall benefits of clean energy investments go to underserved and overburdened communities.

Biden administration pushes to revitalize coal communities with clean energy projects

Coal-to-Clean Energy Hubs leverage Bipartisan Infrastructure Law and Inflation Reduction Act funding to repurpose mine lands with microgrids, advanced nuclear, carbon capture, and rare earth processing, boosting energy security, jobs, and grid modernization.

 

Key Points

They are federal projects converting coal communities and mine lands into clean energy hubs, repurposing infrastructure.

✅ DOE demos on mine lands: microgrids, nuclear, carbon capture.

✅ Funding from BIL, CHIPS and IRA targets energy communities.

✅ Rare earths from coal waste bolster EV supply chains.

 

The Biden administration is channeling hundreds of millions of dollars in clean energy funding from recent legislation into its efforts to turn coal communities into clean energy hubs, the White House said.

The administration gave an update on its push across agencies to kick-start projects nationwide with funding Congress approved during Biden’s first two years in office. The effort includes $450 million from the Bipartisan Infrastructure Law that the Department of Energy will allocate to an array of new clean energy demonstration projects on former mine lands.

“These projects could focus on a range of technologies from microgrids to advanced nuclear to power plans with carbon capture,” Energy Secretary Jennifer Granholm said on a call with reporters Monday. “They’ll prove out the potential to reactivate or repurpose existing infrastructure like transmission lines and substations across an aging U.S. power grid, and these projects could spur new economic development in these communities.”

Among the projects the White House highlighted, it said $16 million from the infrastructure law will go to the University of North Dakota and West Virginia University to create design studies for the first-ever full-scale refinery facility in the U.S. that could extract and separate rare earth elements and minerals from coal mine waste streams. The materials are critical for electric vehicle-battery components that are currently heavily sourced from outside the U.S.

“Those efforts will pave the way toward building a first of its kind facility that produces essential materials for solar panels, wind turbines, EVs and more while cleaning up polluted land and water and creating good-paying jobs for local workers,” Granholm said.

Biden created an interagency working group focused on revitalizing coal-power communities through federal investments when he took office. In 2021, the group selected 25 priority areas ranging from West Virginia to Wyoming to focus on development, as high natural gas prices strengthened the case for clean electricity. There are nearly 18,000 identified mine sites across 1.5 million acres in the United States, according to the White House.

The massive effort fits into a broader Biden administration push to both fight climate change and support communities that have lost economic activity during a transition away from fossil fuel sources such as coal. While Biden’s most ambitious clean energy plans fell flat in Congress in the face of opposition from Republicans and some Democrats after the previous administration’s power plant overhaul, three major laws still unlocked funding for his administration to deploy.

Many of the initiatives are made possible through the Bipartisan Infrastructure Law, Chips and Science Act and the Inflation Reduction Act, even without a clean electricity standard on the books. The task force aims to make sure communities most affected by the changing energy landscape are taking maximum advantage of the federal benefits.

“Those new and expanded operations are coming to energy communities and creating good paying jobs,” Biden’s senior advisor for clean energy innovation and implementation John Podesta said on the call. “These laws can provide substantial federal support to energy communities like capping abandoned oil and gas wells, extracting critical minerals, building battery factories and launching demonstration projects in carbon capture or green hydrogen.”

The administration touted the potential benefits of the Inflation Reduction Act, a bill passed by Democrats to spur clean energy investments last year, even as early assessments show mixed results to date. At the time, U.S. consumers were dealing with decades-high inflation fueled in part by an energy crisis and high gas prices that drove debate — a point Republicans emphasized as the plan moved through Congress.

Deputy Treasury Secretary Wally Adeyemo said the Inflation Reduction Act aims to both “lower the deficit, as well as promote our energy security, lowering energy costs for consumers and combatting climate change.”

“As the Treasury works to implement the law, we’re focused on ensuring that all Americans benefit from the growth of the clean energy economy, particularly those who live in communities that have been dependent on the energy sector for job for a long time,” Adeyemo told reporters. “Economic growth and productivity are higher when all communities are able to reach their full potential.”

Working From Home Will Drive Up Electricity Bills for Consumers

Remote Work Energy Costs are rising as home offices and telecommuting boost electricity bills; utilities, broadband usage, and COVID-19-driven stay-at-home policies affect productivity, consumption patterns, and household budgets across the U.K. and Europe.

 

Key Points

Remote Work Energy Costs are increased household electricity and utility expenses from telecommuting and home office use.

✅ WFH shifts energy load from offices to households.

✅ Higher device, lighting, and heating/cooling usage drives bills.

✅ Broadband access gaps limit remote work equity.

 

Household electricity bills are set to soar, with rising residential electricity use tied to the millions of people now working at home to avoid catching the coronavirus.

Running laptops and other home appliances will cost consumers an extra 52 million pounds ($60 million) each week in the U.K., according to a study from Uswitch, a website that helps consumers compare the energy prices that utilities charge.

For each home-bound household, the pain to the pocketbook may be about 195 pounds per year extra, even as some utilities pursue pandemic cost-cutting to manage financial pressures.

The rise in price for households comes even as overall demand is falling rapidly in Europe, with wide swaths of the economy shut down to keep workers from gathering in one place, and the U.S. grid overseer issuing warnings about potential pandemic impacts on operations.

People stuck at home will plug in computers, lights and appliances when they’d normally be at the office, increasing their consumption.

With the Canadian government declaring a state of emergency due to the coronavirus, companies are enabling work-from-home structures to keep business running and help employees follow social distancing guidelines, and some utilities have even considered housing critical staff on site to maintain operations. However, working remotely has been on the rise for a while.

“The coronavirus is going to be a tipping point. We plodded along at about 10% growth a year for the last 10 years, but I foresee that this is going to really accelerate the trend,” Kate Lister, president of Global Workplace Analytics.

Gallup’s State of the Workplace 2017 study found that 43% of employees work remotely with some frequency. Research indicates that in a five-day workweek, working remotely for two to three days is the most productive. That gives the employee two to three days of meetings, collaboration and interaction, with the opportunity to just focus on the work for the other half of the week.

Remote work seems like a logical precaution for many companies that employ people in the digital economy, even as some federal agencies sparked debate with an EPA telework policy during the pandemic. However, not all Americans have access to the internet at home, and many work in industries that require in-person work.

According to the Pew Research Center, roughly three-quarters of American adults have broadband internet service at home. However, the study found that racial minorities, older adults, rural residents and people with lower levels of education and income are less likely to have broadband service at home. In addition, 1 in 5 American adults access the internet only through their smartphone and do not have traditional broadband access. 

Full-time employees are four times more likely to have remote work options than part-time employees. A typical remote worker is college-educated, at least 45 years old and earns an annual salary of $58,000 while working for a company with more than 100 employees, according to Global Workplace Analytics, and in Canada there is growing interest in electricity-sector careers among younger workers. 

New York, California and other states have enacted strict policies for people to remain at home during the coronavirus pandemic, which could change the future of work, and Canadian provinces such as Saskatchewan have documented how the crisis has reshaped local economies across sectors.

“I don’t think we’ll go back to the same way we used to operate,” Jennifer Christie, chief HR officer at Twitter, told CNBC. “I really don’t.”

Ontario, Quebec to swap energy in new deal to help with electricity demands

Ontario-Quebec Energy Swap streamlines electricity exchange, balancing peak demand across clean grids with hydroelectric and nuclear power, enhancing reliability, capacity banking, and interprovincial load management for industry growth, EV adoption, and seasonal heating-cooling needs.

 

Key Points

10-year, no-cash power swap aligning peaks; hydro and nuclear enhance reliability and let Ontario bank capacity.

✅ Up to 600 MW exchanged yearly; reviews adjust volumes

✅ Peaks differ: summer A/C in Ontario, winter heating in Quebec

✅ Capacity banking enables future-year withdrawals

 

Ontario and Quebec have agreed to swap energy to build on an electricity deal to help each other out when electricity demands peak.

The provinces' electricity operators, the Independent Electricity System Operator holds capacity auctions and Hydro-Quebec, will trade up to 600 megawatts of energy each year, said Ontario Energy Minister Todd Smith.

“The deal just makes a lot of sense from both sides,” Smith said in an interview.

“The beauty as well is that Quebec and Ontario are amongst the cleanest grids around.”

The majority of Ontario's power comes from nuclear energy while the majority of Quebec's energy comes from hydroelectric power, including Labrador power in regional transmission networks.

The deal works because Ontario and Quebec's energy peaks come at different times, Smith said.

Ontario's energy demands spike in the summer, largely driven by air conditioning on hot days, and the province has occasionally set off-peak electricity prices to provide temporary relief, he said.

Quebec's energy needs peak in the winter, mostly due to electric heating on cold days.

The deal will last 10 years, with reviews along the way to adjust energy amounts based on usage.

“With the increase in energy demand, we must adopt more energy efficiency programs like Peak Perks and intelligent measures in order to better manage peak electricity consumption,” Quebec's Energy Minister Pierre Fitzgibbon wrote in a statement.

Smith said the energy deal is a straight swap, with no payments on either side, and won't reduce hydro bills as the transfer could begin as early as this winter.

Ontario will also be able to bank unused energy to save capacity until it is needed in future years, Smith said.

Both provinces are preparing for future energy needs, as electricity demands are expected to grow dramatically in the coming years with increased demand from industry and the rise of electric vehicles, and Ontario has tabled legislation to lower electricity rates to support consumers.

Why Is Central Asia Suffering From Severe Electricity Shortages?

Central Asia power shortages strain grids across Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, and Turkmenistan, driven by drought-hit hydropower, aging coal and gas plants, rising demand, cryptomining loads, and winter peak consumption risks.

 

Key Points

Regionwide blackouts from drought, aging plants and grids, rising demand, and winter peaks stressing Central Asia.

✅ Drought slashes hydropower in Kyrgyzstan, Tajikistan, Uzbekistan

✅ Aging coal and gas TPPs and weak grids cause frequent outages

✅ Cryptomining loads and winter heating spike demand and stress supply

 

Central Asians from western Kazakhstan to southern Tajikistan are suffering from power and energy shortages that have caused hardship and emergency situations affecting the lives of millions of people.

On October 14, several units at three power plants in northeastern Kazakhstan were shut down in an emergency that resulted in a loss of more than 1,000 megawatts (MW) of electricity.

It serves as an example of the kind of power failures that plague the region 30 years after the Central Asian countries gained independence and despite hundreds of millions of dollars being invested in energy infrastructure and power grids, and echo risks seen in other advanced markets such as Japan's near-blackouts during recent cold snaps.

Some of the reasons for these problems are clear, but with all the money these countries have allocated to their energy sectors and financial help they have received from international financial institutions, it is curious the situation is already so desperate with winter officially still weeks away.


The Current Problems
Three power plants were affected in the October 14 shutdowns of units: Ekibastuz-1, Ekibastuz-2, and the Aksu power plant.

Ekibastuz-1 is the largest power plant in Kazakhstan, capable of generating some 4,000 MW, roughly 13 percent of Kazakhstan’s total power output.

The Kazakhstan Electricity Grid Operating Company (KEGOC) explained the problems resulted partially from malfunctions and repair work, but also from overuse of the system that the government would later say was due to cryptominers, a large number of whom have moved to Kazakhstan recently from China after Beijing banned the mining needed by Bitcoin and other cryptocurrencies, amid its own China's power cuts across several provinces in 2021.

But between November 8 and 9, rolling blackouts were reported in the East Kazakhstan, North Kazakhstan, and Kyzylorda provinces, as well as the area around Almaty, Kazakhstan’s biggest city, and Shymkent, its third largest city.

People in Uzbekistan say they, too, are facing blackouts that the Energy Ministry described as “short-term outages,” even as authorities have looked to export electricity to Afghanistan to support regional demand, though it has been clear for several weeks that the country will have problems with natural gas supplies this winter.


Power lines in Uzbekistan
Kyrgyz President Sadyr Japarov continues to say there won't be any power rationing in Kyrgyzstan this winter, but at the end of September the National Energy Holding Company ordered “restrictions on the lighting of secondary streets, advertisements, and facades of shops, cafes, and other nonresidential customers.”

Many parts of Tajikistan are already experiencing intermittent supplies of electricity.

Even in Turkmenistan, a country with the fourth-largest reserves of natural gas in the world, there were reports of problems with electricity and heating in the capital, Ashgabat.


What Is Going On?
The causes of some of these problems are easy to see.

The population of the region has grown significantly, with the population of Central Asia when the Soviet Union collapsed in late 1991 being some 50 million and today about 75 million.

Kyrgyzstan and Tajikistan are mountainous countries that have long been touted for their hydropower potential and some 90 percent of Kyrgyzstan’s domestically produced electricity and 98 percent of Tajikistan’s come from hydropower.

But a severe drought that struck Central Asia this year has resulted in less hydropower and, in general, less energy for the region, similar to constraints seen in Europe's reduced hydro and nuclear output this year.

Tajik authorities have not reported how low the water in the country’s key reservoirs is, but Kyrgyzstan has reported the water level in the reservoir at its Toktogul hydropower plant (HPP) is 11.8 billion cubic meters (bcm), the lowest level in years and far less than the 14.7 bcm of water it had in November 2020.

The Toktogul HPP, with an installed capacity of 1,200 MW, provides some 40 percent of the country's domestically produced electricity, but operating the HPP this winter to generate desperately needed energy brings the risk of leaving water levels at the reservoir critically low next spring and summer when the water is also needed for agricultural purposes.

This year’s drought is something Kyrgyzstan and Tajikistan will have to take into consideration as they plan how to provide power for their growing populations in the future. Hydropower is a desirable option but may be less reliable with the onset of climate change, prompting interest in alternatives such as Ukraine's wind power to diversify generation.

Uzbekistan is also feeling the effects of this year’s drought, and, like the South Caucasus where Georgia's electricity imports have increased, supply shortfalls are testing grids.

According to the International Energy Agency, HPPs account for some 12 percent of Uzbekistan’s generating capacity.

Uzbekistan’s Energy Ministry attributed low water levels at HPPs that have caused a 23 percent decrease in hydropower generation this year.


A reservoir in Kyrgyzstan
Kazakhstan and Uzbekistan are the most populous Central Asian countries, and both depend on thermal power plants (TPP) for generating most of their electricity.

Most of the TPPs in Kazakhstan are coal-fired, while most of the TPPs in Uzbekistan are gas-fired.

Kazakhstan has 68 power plants, 80 percent of which are coal-fired TPPs, and most are in the northern part of the country where the largest deposits of coal are located. Kazakhstan has the world's 10th largest reserves of coal.

About 88 percent of Uzbekistan’s electricity comes from TTPs, most of which use natural gas.

Uzbekistan’s proven reserves are some 800 billion cubic meters, but gas production in Uzbekistan has been decreasing.

In December 2020, Uzbek President Shavkat Mirziyoev ordered a halt to the country’s gas exports and instructed that gas to be redirected for domestic use. Mirziyoev has already given similar instructions for this coming winter.


How Did It Come To This?
The biggest problem with the energy infrastructure in Central Asia is that it is generally very old. Nearly all of its power plants date back to the Soviet era -- and some well back into the Soviet period.

The use of power plants and transmission lines that some describe as “obsolete” and a few call “decrepit” has unfortunately been a necessity in Central Asia, even as regional players pursue new interconnections like Iran's plan to transmit electricity to Europe as a power hub.

Reporting on Kazakhstan in September 2016, the Asian Development Bank (ADB) said, “70 percent of the power generation infrastructure is in need of rehabilitation.”

The Ekibastuz-1 TPP is relatively new by the power-plant standards of Central Asia. The first unit of the eight units of the TPP was commissioned in 1980.

The first unit at the AKSU TPP was commissioned in 1968, and the first unit of the gas- and fuel-fired TPP in southern Kazakhstan’s Zhambyl Province was commissioned in 1967.

A Texas-Sized Gas-for-Electricity Swap

Texas Heat Pump Electrification replaces natural gas furnaces with electric heating across ERCOT, cutting carbon emissions, lowering utility bills, shifting summer peaks to winter, and aligning higher loads with strong seasonal wind power generation.

 

Key Points

Statewide shift from gas furnaces to heat pumps in Texas, reducing emissions and bills while moving grid peak to winter.

✅ Up to $452 annual utility savings per household

✅ CO2 cuts up to 13.8 million metric tons in scenarios

✅ Winter peak rises, summer peak falls; wind aligns with load

 

What would happen if you converted all the single-family homes in Texas from natural gas to electric heating?

According to a paper from Pecan Street, an Austin-based energy research organization, the transition would reduce climate-warming pollution, save Texas households up to $452 annually on their utility bills, and flip the state from a summer-peaking to a winter-peaking system. And that winter peak would be “nothing the grid couldn’t evolve to handle,” according to co-author Joshua Rhodes, a view echoed by analyses outlining Texas grid reliability improvements statewide today.

The report stems from the reality that buildings must be part of any comprehensive climate action plan.

“If we do want to decarbonize, eventually we do have to move into that space. It may not be the lowest-hanging fruit, but eventually we will have to get there,” said Rhodes.

Rhodes is a founding partner of the consultancy IdeaSmiths and an analyst at Vibrant Clean Energy. Pecan Street commissioned the study, which is distilled from a larger original analysis by IdeaSmiths, at the request of the nonprofit Environmental Defense Fund.

In an interview, Rhodes said, “The goal and motivation were to put bounding on some of the claims that have been made about electrification: that if we electrify a lot of different end uses or sectors of the economy...power demand of the grid would double.”

Rhodes and co-author Philip R. White used an analysis tool from the National Renewable Energy Laboratory called ResStock to determine the impact of replacing natural-gas furnaces with electric heat pumps in homes across the ERCOT service territory, which encompasses 90 percent of Texas’ electricity load.

Rhodes and White ran 80,000 simulations in order to determine how heat pumps would perform in Texas homes and how the pumps would impact the ERCOT grid.

The researchers modeled the use of “standard efficiency” (ducted, SEER 14, 8.2 HSPF air-source heat pump) and “superior efficiency” (ductless, SEER 29.3, 14 HSPF mini-split heat pump) heat pump models against two weather data sets — a typical meteorological year, and 2011, which had extreme weather in both the winter and summer and highlighted blackout risks during severe heat for many regions.

Emissions were calculated using Texas’ power sector data from 2017. For energy cost calculations, IdeaSmiths used 10.93 cents per kilowatt-hour for electricity and 8.4 cents per therm for natural gas.

Nothing the grid can't handle
Rhodes and White modeled six scenarios. All the scenarios resulted in annual household utility bill savings — including the two in which annual electricity demand increased — ranging from $57.82 for the standard efficiency heat pump and typical meteorological year to $451.90 for the high-efficiency heat pump and 2011 extreme weather year.

“For the average home, it was cheaper to switch. It made economic sense today to switch to a relatively high-efficiency heat pump,” said Rhodes. “Electricity bills would go up, but gas bills can go down.”

All the scenarios found carbon savings too, with CO2 reductions ranging from 2.6 million metric tons with a standard efficiency heat pump and typical meteorological year to 13.8 million metric tons with the high-efficiency heat pump in 2011-year weather.

Peak electricity demand in Texas would shift from summer to winter. Because heat pumps provide both high-efficiency space heating and cooling, in the scenario with “superior efficiency” heat pumps, the summer peak drops by nearly 24 percent to 54 gigawatts compared to ERCOT’s 71-gigawatt 2016 summer peak, even as recurring strains on the Texas power grid during extreme conditions persist.

The winter peak would increase compared to ERCOT’s 66-gigawatt 2018 winter peak, up by 22.73 percent to 81 gigawatts with standard efficiency heat pumps and up by 10.6 percent to 73 gigawatts with high-efficiency heat pumps.

“The grid could evolve to handle this. This is not a wholesale rethinking of how the grid would have to operate,” said Rhodes.

He added, “There would be some operational changes if we went to a winter-peaking grid. There would be implications for when power plants and transmission lines schedule their downtime for maintenance. But this is not beyond the realm of reality.”

And because Texas’ wind power generation is higher in winter, a winter peak would better match the expected higher load from all-electric heating to the availability of zero-carbon electricity.

 

A conservative estimate
The study presented what are likely conservative estimates of the potential for heat pumps to reduce carbon pollution and lower peak electricity demand, especially when paired with efficiency and demand response strategies that can flatten demand.

Electric heat pumps will become cleaner as more zero-carbon wind and solar power are added to the ERCOT grid, as utilities such as Tucson Electric Power phase out coal. By the end of 2018, 30 percent of the energy used on the ERCOT grid was from carbon-free sources.

According to the U.S. Energy Information Administration, three in five Texas households already use electricity as their primary source of heat, much of it electric-resistance heating. Rhodes and White did not model the energy use and peak demand impacts of replacing that electric-resistance heating with much more energy efficient heat pumps.

“Most of the electric-resistance heating in Texas is located in the very far south, where they don’t have much heating at all,” Rhodes said. “You would see savings in terms of the bills there because these heat pumps definitely operate more efficiently than electric-resistance heating for most of the time.”

Rhodes and White also highlighted areas for future research. For one, their study did not factor in the upfront cost to homeowners of installing heat pumps.

“More study is needed,” they write in the Pecan Street paper, “to determine the feasibility of various ‘replacement’ scenarios and how and to what degree the upgrade costs would be shared by others.”

Research from the Rocky Mountain Institute has found that electrification of both space and water heating is cheaper for homeowners over the life of the appliances in most new construction, when transitioning from propane or heating oil, when a gas furnace and air conditioner are replaced at the same time, and when rooftop solar is coupled with electrification, aligning with broader utility trends toward electrification.

More work is also needed to assess the best way to jump-start the market for high-efficiency all-electric heating. Rhodes believes getting installers on board is key.

“Whenever a homeowner’s making a decision, if their system goes out, they lean heavily on what the HVAC company suggests or tells them because the average homeowner doesn’t know much about their systems,” he said.

More work is also needed to assess the best way to jump-start the market for high-efficiency all-electric heating, and how utility strategies such as smart home network programs affect adoption too. Rhodes believes getting installers on board is key.
