Accountants Face Grilling in Enron Trial

U.S. Climate Change Donation Survey reveals Americans' willingness to fund sustainability via government incentives, electrification, and renewable energy. Public opinion favors wind, solar, and decarbonization, highlighting policy support post-pandemic amid economic recovery efforts.

Key Points

A 2020 U.S. poll on climate attitudes: donation willingness, renewable support, and views on government incentives.

✅ 70% would donate income; 31% would donate nothing.

✅ 59% prefer government incentives; 47% support taxes, conservation.

✅ 85% land wind, 83% offshore wind, 90% solar support.

A new study of American consumers' attitudes toward climate change finds that more than two-thirds of respondents (70%) indicate their willingness to give or donate a percentage of their personal income to support the fight against climate change and the path to net-zero electricity emissions by mid-century. 

Twenty-eight percent indicated they were willing to provide less than 1% of their income; 33% said they would be willing to contribute 1-5% of their income; 6% said they would give between 6-10% of their income; and 3% indicated they would contribute more than 10% of their income. Just under one-third (31%) of those surveyed indicated they were unwilling to give or donate any percentage of their income to support the fight against climate change.

The U.S. findings are part of a series of surveys commissioned by Nexans in the U.S., UK and France, in order to determine public opinion on climate change and related issues in the wake of the COVID-19 pandemic. The U.S. study was conducted online by Researchscape from August 20 – 24, 2020. It had 1,013 respondents, ages 18 or older, with the results weighted to be representative of the overall population (variables available upon request).

Nexans, is headquartered in Paris with a major offshore wind cable manufacturing facility in Charleston, S.C. and an industrial cable manufacturing facility in El Dorado, Ark. The company is fully committed to fighting climate change and is helping to make sustainable electrification possible. The survey was developed as part of its celebration of the first Climate Day in Paris which included a roundtable event with world-renowned experts, the release of an unprecedented global study by Roland Berger on the challenges raised by the electrification of the world, the question of whether the global energy transition is on track, and Nexans' own commitment to be carbon neutral by 2030.

Paying the Tab to Address Climate Change

Participants were given the opportunity to choose from seven multiple responses to the question "How should the fight against climate change be paid for?" The majority (59%) replied it should be paid for by "government incentives for both businesses and consumers." It was followed by "federal, state and/or local taxes" and "conservation programs" (tied at 47%); "business investments" (42%), such as carbon-free electricity initiatives, and "consumer-driven purchases" (33%). Just 9% selected none of the above and 2% selected other.

"Through the organization of this Climate Day, Nexans is asserting itself not only as an actor but also a thought leader of the energy transition for a sustainable electrification of the world. This electrification raises a number of challenges and paradoxes that must be overcome. And it will only happen with the direct involvement of the populations concerned. These surveys provide a better understanding of the level of information and disinformation, including climate change denial, in public opinion as well as their level of acceptability of these lifestyle changes," said Christopher Guérin, CEO, Nexans.

Among other findings, 44% are dissatisfied with the job that federal and state governments are doing to address climate change, while utilities like Duke Energy face investor pressure to release climate reports, 35% are somewhat satisfied and 21% are either very satisfied or completed satisfied with government's role.

Americans expressed overwhelmingly favorable views of wind and solar renewable energy proposals, as carbon emissions fall when electricity producers move away from coal. Specifically, 85% stated being in favor of wind turbines on land (15% against), 83% in favor of wind turbines off the coast (17% against) and 90% in support of solar panel farms (10% opposed).

Those surveyed were asked about their current and changing priorities towards climate change as influenced by the coronavirus pandemic and impacts like extreme heat on electricity bills. Thirty-nine percent indicated that climate change was no more and no less a priority due to the current health emergency; just under a third (31%) indicated that climate change is more of a priority while 30% said it was less of a priority.

In similar research conducted by Nexans in the United Kingdom, nearly two thirds (65.8%) of UK respondents said they would be willing to donate part of their salary to fight climate change. Furthermore, nearly a third (29%) of the UK's consumers believe that combating climate change has become more of a priority in light of the coronavirus pandemic. The UK research was conducted online by Savanta from August 21 – 24, 2020. A total of 2210 respondents, aged 16 and above, representative of the UK population took part.

Heathrow Airport Power Outage 2025 disrupted operations with mass flight cancellations and diversions after a grid failure, exposing infrastructure resilience gaps, crisis management flaws, and raising passenger compensation and safety oversight concerns.

Key Points

A grid failure closed Heathrow, causing mass cancellations and diversions, exposing resilience and communication lapses.

✅ Grid fire triggered airport-wide shutdown

✅ 1,400+ flights canceled or diverted

✅ Inquiry probes resilience, communication, compensation

On March 21, 2025, Heathrow Airport, Europe's busiest, suffered a catastrophic power outage, similar to another high-profile outage seen at major events, that led to the cancellation and diversion of over 1,400 flights, affecting nearly 300,000 passengers and costing airlines an estimated £100 million. The power failure, triggered by a fire at an electricity substation in west London, left Heathrow with a significant operational crisis. This disruption is even more significant considering that Heathrow is one of the most expensive airports globally, which raises concerns about its infrastructure resilience and broader electricity system resilience across Europe.

In a parliamentary committee meeting, Heathrow officials admitted that vulnerabilities in the airport’s power supply were flagged just days before the outage. Nigel Wicking, Chief Executive of the Heathrow Airline Operators' Committee (HAOC), informed MPs that concerns regarding power resilience had been raised on March 15, following disruptions caused by cable thefts impacting runway lights. Despite these warnings, the airport’s management did not address the vulnerabilities urgently, even as UK net zero policies continue to reshape infrastructure planning, which ultimately led to the disastrous outage.

The airport was closed for a day, with serious consequences for not only airlines but also the surrounding community and businesses. British Airways alone faced millions of pounds in losses, and passengers experienced significant emotional distress, missing vital life events like weddings and funerals due to flight cancellations. The committee is now questioning officials from National Grid and Scottish and Southern Electricity Networks to better understand why Heathrow’s infrastructure failed, in the context of a cleaner grid following the British carbon tax that reduced coal use, how it communicated with affected parties, and what measures will be taken to compensate impacted passengers.

Heathrow’s Chief Executive, Thomas Woldbye, defended the closure decision, stating it would have been disastrous to keep the airport open under such circumstances. He noted that continuing operations would have left tens of thousands of passengers stranded and would have posed safety risks due to the failure of fire surveillance and CCTV systems. However, Wicking, representing the airlines, pointed out that Heathrow’s lack of resilience was unacceptable given the amount spent on the airport, emphasizing the need for better infrastructure, including addressing SF6 in switchgear during upgrades, and more transparent management practices.

Looking forward, the MPs intend to investigate the airport’s emergency preparedness, why the resilience review from 2018 wasn’t shared with airlines, and whether enough preventative measures were in place amid surging data demand that could strain electricity supplies. The outcome of this inquiry could have lasting effects on how Heathrow and other major airports handle their infrastructure and crisis management systems, as drought-driven hydro challenges demonstrate the wider climate stresses on power networks.

European Green Deal Electrification accelerates decarbonization via renewables, electric vehicles, heat pumps, and clean industry, backed by sustainable finance, EIB green lending, just transition funds, and energy taxation reform to phase out fossil fuels.

Key Points

An EU plan to replace fossil fuels with renewable electricity in transport, buildings, and industry, supported by green finance.

✅ Doubles electricity's share to cut CO2 and phase out fossil fuels.

✅ Drives EVs, heat pumps, and electrified industry via renewables.

✅ Funded by EIB lending, EU budget, and just transition support.

The European Union is preparing an ambitious plan to completely decarbonize by 2050. Increasing the share of electricity in Europe’s energy system – electricity that will increasingly come from renewable sources - will be at the center of this strategy, aligning with the broader global energy transition under way, the new head of the European Commission’s energy department said yesterday.

This will mean more electric cars, electric heating and electric industry. The idea is that fossil fuels should no longer be a primary energy source, heating homes, warming food or powering cars. In the medium term they should only be used to generate electricity, a shift mirrored by New Zealand's electricity shift efforts, which then powers these things, resulting in less CO2 emissions.

“First assessments show we need to double the share of electricity in energy consumption by 2050,” Ditte Juul-Jørgensen said at an event in Brussels this week, a goal echoed by recent calls to double investment in power systems from world leaders. “We’ve already seen an increase in the last decade, but we need to go further”.

Juul-Jørgensen, who started in her job as director-general of the commission’s energy department in August, has come to the role at a pivotal time for energy. The 2050 decarbonization proposal from the Commission, the EU’s executive branch, is expected to be approved next month by EU national leaders. A veto from Poland that has blocked adoption until now is likely to be overcome if Poland and other Eastern European countries are offered financial assistance from a “just transition fund”, according to EU sources.

Ursula von der Leyen, the incoming President of the Commission, has promised to unveil a “European Green Deal” in her first 100 days in office designed to get the EU to its 2050 goal. Juul-Jørgensen will be working with the incoming EU Energy Commissioner, Kadri Simson, on designing this complex strategy. The overall aim will be to phase out fossil fuels, and increase the use of electricity from green sources, amid trends like oil majors pivoting to electric across Europe today.

“This will be about how do we best make use of electricity to feed into other sectors,” Juul-Jørgensen said. “We need to think about transforming it into other sources, and how to best transport it.”

“But the biggest challenge from what I see today is that of investment and finance - the changes we have to make are very significant.”

Financing problems

The Commission is going to try to tackle the challenges of financing the energy transition with two tools: dedicated climate funding in the EU budget, and dedicated climate lending from the European Investment Bank.

“The EIB will play an increasing role in future. We hope to see agreement [with the EIB board] on that in the coming months so there’s a clear operator in the EIB to support the green transition. We’re looking at something around €400 billion a year.”

The Commission’s proposed dedicated climate spending in the next seven-year budget must still be approved by the 28 EU national governments. Juul-Jørgensen said there is unanimous agreement on the amount: 25% of the budget. But there is disagreement about how to determine what is green spending.

“A lot of work has been ongoing to ensure that when it comes to counting it reflects the reality of the investments,” she said. “We’re working on the taxonomy on sustainable finance - internally identifying sectors contributing to overall climate objectives.”

Electricity pact

Juul-Jørgensen was speaking at an event organized by the the Electrification Alliance, a pact between nine industry organizations to lobby for electricity to be put at the heart of the European green deal. They signed a declaration at the event calling for a variety of measures to be included in the green deal, reflecting debates over a fully renewable grid by 2030 in other jurisdictions, including a change to the EU’s energy taxation regime which incentivizes a switch from fossil fuel to electricity consumption.

“Electrification is the most important solution to turn the vision of a fossil-free Europe into reality,” said Laurence Tubiana, CEO of the European Climate Foundation, one of the signatories, and co-architect of the Paris Agreement.

“We are determined to deliver, but we must be mindful of the different starting points and secure sufficient financing to ensure a fair transition”, said Magnus Hall, President of electricity industry association Eurelectric, another signatory.

The energy taxation issue has been particularly tricky for the EU, since any change in taxation rules requires the unanimous consent of all 28 EU countries. But experts say that current taxation structures are subsidizing fossil fuels and punishing electricity, as recent UK net zero policy changes illustrate, and unless this is changed the European Green Deal can have little effect.

“Yes this issue will be addressed in the incoming commission once it takes up its function,” Juul-Jørgensen said in response to an audience question. “We all know the challenge - the unanimity requirement in the Council - and so I hope that member states will agree to the direction of work and the need to address energy taxation systems to make sure they’re consistent with the targets we’ve set ourselves.”

But some are concerned that the transformation envisioned by the green deal will have negative impacts on some of the most vulnerable members of society, including those who work in the fossil fuel sector.

This week the Centre on Regulation in Europe sent an open letter to Frans Timmermans, the Commission Vice President in charge of climate, warning that they need to be mindful of distributional effects. These worries have been heightened by the yellow vest protests in France, which were sparked by French President Emmanuel Macron’s attempt to increase fuel taxes for non-electric cars.

“The effectiveness of climate action and sustainability policies will be challenged by increasing social and political pressures,” wrote Máximo Miccinilli, the center’s director for energy. “If not properly addressed, those will enhance further populist movements that undermine trust in governance and in the public institutions.”

Miccinilli suggests that more research be done into identifying, quantifying and addressing distributional effects before new policies are put in place to phase out fossil fuels. He proposes launching a new European Observatory for Distributional Effects of the Energy Transition to deal with this.

EU national leaders are expected to vote on the 2050 decarbonization target, building on member-state plans such as Spain's 100% renewable electricity goal by mid-century, at a summit in Brussels on December 12, and Von der Leyen will likely unveil her European Green Deal in March.

Ontario Electricity Capacity Gap threatens reliability as IESO forecasts shortfalls from the Pickering shutdown and rapid electrification, requiring new low-emission nuclear generation to meet net-zero targets, maintain baseload, and stabilize the grid.

Key Points

Expected 2030 shortfalls from Pickering closure and electrification, requiring new low-emission nuclear to meet net-zero.

✅ IESO projects a 3.6-9.5 GW capacity gap by 2030

✅ Pickering shutdown removes baseload, stressing reliability

✅ New low-emission nuclear needed to meet net-zero targets

Ontario faces an electricity supply shortage and reliability risks in the next four to eight years and will not meet net-zero objectives without building new low-emission, nuclear generation starting as soon as possible, according to a report released yesterday by the Power Workers' Union (PWU). The capacity needed to fill the expected supply gap will be equivalent to doubling the province's planned nuclear fleet in eight years.

The planned closure of the Pickering nuclear power plant in 2025 and the increase in demand from electrification of the economy are the drivers behind a capacity gap in 2030 of at least 3.6 GW which could widen to as much as 9.5 GW, Electrification Pathways for Ontario to Reduce Emissions, finds. Ontario's Independent Electricity System Operator (IESO) has since 2013 been forecasting a significant gap in the province's electricity supply due the closure of Pickering, but has been underestimating the impact of electrification, the report says.

In addition, the electrification of buildings, transport and industry sectors that will be needed to achieve goals of net-zero emissions by 2050 that being set by the federal government and civil society will see the province's electricity demand increase by at least 130% over current planning forecasts, and potentially by over 190%. Leveraging electricity, natural gas and hydrogen synergies can reduce supply needs, but 55 GW of new electricity capacity, including new large-scale nuclear plants, will still be needed by 2050 - four times Ontario's current nuclear and hydro assets - the report finds.

These findings underscore the urgent need for a paradigm shift in Ontario's electricity planning and procurement process, the authors say, adding that immediate action is needed both to mitigate the system reliability risks and enable the significant societal benefits needed to pursue net-zero objectives. Planning for procurement to replace Pickering's capacity, or to pursue life extension options, must begin as soon as possible.

"Policymakers around the world realise climate change can't be tackled without nuclear. Ontario's nuclear fleet has delivered emissions reductions for over 50 years," PWU President Jeff Parnell said. "In fact, without building new nuclear units, Ontario will miss its emission reduction targets and carbon emissions from electricity generation will rise dramatically, as explored in why Ontario's power could get dirtier today."

"This report clearly shows that Ontario cannot sustain the low-carbon status of its hydro and nuclear-based electricity system, decarbonise its economy and meet its carbon reduction targets without new nuclear or continued operation at Pickering in the near term. Most disturbing is the fact that we are already well behind and needed to start planning for this capacity yesterday," he said.

The six operating Candu reactors at Ontario Power Generation's Pickering plant have been kept in operation to provide baseload electricity during the refurbishment of units at the Darlington and Bruce plants. Currently, the company plans to shut down Pickering units 1 and 4 in 2024 and units 5 to 8 in 2025, even as Ontario moves to refurbish Pickering B to extend life.

Solar-Wind-Water West Africa integrates hydropower with solar and wind to boost grid flexibility, clean electricity, and decarbonization, leveraging the West African Power Pool and climate data modeling reported in Nature Sustainability.

Key Points

A strategy using hydropower to balance solar and wind, enabling reliable, low-carbon electricity across West Africa.

✅ Hydropower dispatch covers solar and wind shortfalls.

✅ Regional interconnection via West African Power Pool.

✅ Cuts CO2 versus gas while limiting new dam projects.

Hydropower plants can support solar and wind power, rather unpredictable by nature, in a climate-friendly manner. A new study in the scientific journal Nature Sustainability has now mapped the potential for such "solar-wind-water" strategies for West Africa: an important region where the power sector is still under development, amid IEA investment needs for universal access, and where generation capacity and power grids will be greatly expanded in the coming years. "Countries in West Africa therefore now have the opportunity to plan this expansion according to strategies that rely on modern, climate-friendly energy generation," says Sebastian Sterl, energy and climate scientist at Vrije Universiteit Brussel and KU Leuven and lead author of the study. "A completely different situation from Europe, where power supply has been dependent on polluting power plants for many decades - which many countries now want to rid themselves of."

Solar and wind power generation is increasing worldwide and becoming cheaper and cheaper. This helps to keep climate targets in sight, but also poses challenges. For instance, critics often argue that these energy sources are too unpredictable and variable to be part of a reliable electricity mix on a large scale, though combining multiple resources can enhance project performance.

"Indeed, our electricity systems will have to become much more flexible if we are to feed large amounts of solar and wind power into the grid. Flexibility is currently mostly provided by gas power plants. Unfortunately, these cause a lot of CO2 emissions," says Sebastian Sterl, energy and climate expert at Vrije Universiteit Brussel (VUB) and KU Leuven. "But in many countries, hydropower plants can be a fossil fuel-free alternative to support solar and wind energy. After all, hydropower plants can be dispatched at times when insufficient solar and wind power is available."

The research team, composed of experts from VUB, KU Leuven, the International Renewable Energy Agency (IRENA), and Climate Analytics, designed a new computer model for their study, running on detailed water, weather and climate data. They used this model to investigate how renewable power sources in West Africa could be exploited as effectively as possible for a reliable power supply, even without large-scale storage, in line with World Bank support for wind in developing countries. All this without losing sight of the environmental impact of large hydropower plants.

"This is far from trivial to calculate," says Prof. Wim Thiery, climate scientist at the VUB, who was also involved in the study. "Hydroelectric power stations in West Africa depend on the monsoon; in the dry season they run on their reserves. Both sun and wind, as well as power requirements, have their own typical hourly, daily and seasonal patterns. Solar, wind and hydropower all vary from year to year and may be impacted by climate change, including projections that wind resources shift southward in coming years. In addition, their potential is spatially very unevenly distributed."

West African Power Pool

The study demonstrates that it will be particularly important to create a "West African Power Pool", a regional interconnection of national power grids to serve as a path to universal electricity access across the region. Countries with a tropical climate, such as Ghana and the Ivory Coast, typically have a lot of potential for hydropower and quite high solar radiation, but hardly any wind. The drier and more desert-like countries, such as Senegal and Niger, hardly have any opportunities for hydropower, but receive more sunlight and more wind. The potential for reliable, clean power generation based on solar and wind power, supported by flexibly dispatched hydropower, increases by more than 30% when countries can share their potential regionally, the researchers discovered.

All measures taken together would allow roughly 60% of the current electricity demand in West Africa to be met with complementary renewable sources, despite concerns about slow greening of Africa's electricity, of which roughly half would be solar and wind power and the other half hydropower - without the need for large-scale battery or other storage plants. According to the study, within a few years, the cost of solar and wind power generation in West Africa is also expected to drop to such an extent that the proposed solar-wind-water strategies will provide cheaper electricity than gas-fired power plants, which currently still account for more than half of all electricity supply in West Africa.

Better ecological footprint

Hydropower plants can have a considerable negative impact on local ecology. In many developing countries, piles of controversial plans for new hydropower plants have been proposed. The study can help to make future investments in hydropower more sustainable. "By using existing and planned hydropower plants as optimally as possible to massively support solar and wind energy, one can at the same time make certain new dams superfluous," says Sterl. "This way two birds can be caught with one stone. Simultaneously, one avoids CO2 emissions from gas-fired power stations and the environmental impact of hydropower overexploitation."

Global relevance

The methods developed for the study are easily transferable to other regions, and the research has worldwide relevance, as shown by a US 80% study on high variable renewable shares. Sterl: "Nearly all regions with a lot of hydropower, or hydropower potential, could use it to compensate shortfalls in solar and wind power." Various European countries, with Norway at the front, have shown increased interest in recent years to deploy their hydropower to support solar and wind power in EU countries. Exporting Norwegian hydropower during times when other countries undergo solar and wind power shortfalls, the European energy transition can be advanced.

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.
