MidAmerican Energy expects to generate 25 percent of its electricity from wind by the end of this year after placing 142 additional wind turbines into service in January.

The turbines began operating in Pocahontas, Wright and Hamilton counties, bringing MidAmerican's Iowa total to 466. The Des Moines-based utility announced that it had activated the turbines at the Pomeroy Wind Project in Pocahontas County and the Century Project Expansion near Blairsburg.

By the end of 2008, MidAmerican expects to have another 260 wind turbines operating in Iowa, bringing the total to 726. They will be capable of supplying power to about 390,000 average homes. MidAmerican began building wind projects in 2004. The company operates more wind generation than any other regulated utility in the United States.

In addition to the turbines, MidAmerican is investing $400 million between 2004 and 2009 on environmental upgrades to reduce emissions at its fossil-fuel burning power plants. The work will reduce emissions of nitrogen oxides by 44 percent, sulfur dioxide by 38 percent and mercury by 35 percent.

President Bill Fehrman acknowledged the company's role in fighting climate change.

"Global climate change is a complex issue, and there are many factors over which the company has no control; however, we will continue to take responsible actions that help us do our part to economically move toward a lower-carbon society in our country," he said in a statement.

About 25 percent of the electricity produced by MidAmerican will come from non-carbon resources at the end of 2008. Officials said the company's unit price of electricity is now lower than it was in 1994, and it has pledged to keep electric rates stable until at least 2014.

Iowa has more wind generation capacity than all except three other states, according to the American Wind Energy Association. Wind developers added 337 megawatts of generating capacity in Iowa last year, bringing the total to 1,273 megawatts from 936 at the end of 2006, the association said.

The Pomeroy project developed for MidAmerican by enXco was the largest wind project developed in the state last year, the group said.

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.

More Managers Charged For Price Fixing At Ukraine Power Producer

DTEK Rotterdam+ price-fixing case scrutinizes alleged collusion over coal-based electricity tariffs in Ukraine, with NABU probing NERC regulators, market manipulation, consumer overpayment, and wholesale pricing tied to imported coal benchmarks.

 

Key Points

NABU probes alleged DTEK-NERC collusion to inflate coal power tariffs via Rotterdam+; all suspects deny wrongdoing.

✅ NABU alleges tariff manipulation tied to coal import benchmarks.

✅ Four DTEK execs and four NERC officials reportedly charged.

✅ Probe centers on 2016-2017 overpayments; defendants contest.

 

Two more executives of DTEK, Ukraine’s largest private power and coal producer and recently in energy talks with Octopus Energy, have been charged in a criminal case on August 14 involving an alleged conspiracy to fix electricity prices with the state energy regulator, Interfax reported.

They are Ivan Helyukh, the CEO of subsidiary DTEK Grid, which operates as Ukraine modernizes its network alongside global moves toward a smart electricity grid, and Borys Lisoviy, a top manager of power generation company Skhidenergo, according to Kyiv-based Concorde Capital investment bank.

Ukraine’s Anti-Corruption Bureau (NABU) alleges that now four DTEK managers “pressured” and colluded with four regulators at the National Energy and Utilities Regulatory Commission to manipulate tariffs on electricity generated from coal that forced consumers to overpay, reflecting debates about unjustified profits in the UK, $747 million in 2016-2017.

 

DTEK allegedly benefited $560 million in the scheme.

All eight suspects are charged with “abuse of office” and deny wrongdoing, similar to findings in a B.C. Hydro regulator report published in Canada.

There is “no legitimate basis for suspicions set out in the investigation,” DTEK said in an August 8 statement.

Suspect Dmytro Vovk, the former head of NERC, dismissed the investigation as a “wild goose chase” on Facebook.

In separate statements over the past week, DTEK said the managers who are charged have prematurely returned from vacation to “fully cooperate” with authorities in order to “help establish the truth.”

A Kyiv court on August 14 set bail at $400,000 for one DTEK manager who wasn’t named, as enforcement actions like the NT Power penalty highlight regulatory consequences.

The so-called Rotterdam+ pricing formula that NABU has been investigating since March 2017, similar to federal scrutiny of TVA rates, was in place from April 2016 until July of this year.

It based the wholesale price of electricity by Ukrainian thermal power plants on coal prices set in the Rotterdam port plus delivery costs to Ukraine.

NABU alleges that at certain times it has not seen documented proof that the purchased coal originated in Rotterdam, insisting that there was no justification for the price hikes, echoing issues around paying for electricity in India in some markets.

Ukraine started facing thermal-coal shortages after fighting between government forces and Russia-backed separatists in the eastern part of the country erupted in April 2014. A vast majority of the anthracite-coal mines on which many Ukrainian plants rely are located on territory controlled by the separatists.

Overnight, Ukraine went from being a net exporter of coal to a net importer and started purchasing coal from as far away as South Africa and Australia.

China's nuclear energy on steady development track, say experts

China Nuclear Power Expansion accelerates with reactor approvals, Hualong One and CAP1400 deployments, rising gigawatts, clean energy targets, carbon neutrality goals, and grid reliability benefits to meet coastal demand and reduce emissions.

 

Key Points

An accelerated reactor buildout to add clean capacity, curb emissions, and improve grid reliability nationwide.

✅ Approvals surge for Hualong One and CAP1400 third-gen reactors

✅ Capacity targets approach 100 GW installed by 2030

✅ Supports carbon neutrality, energy security, and lower costs

 

While China has failed to accomplish its 2020 nuclear target of 58 gigawatts under operation and 30 GW under construction, insiders are optimistic about prospects for the nonpolluting energy resource in China over the next five years as the country has stepped up nuclear approvals and construction since 2020.

China expects to record 49 operating nuclear facilities and capacity of more than 51 GW as of the end of 2020. Nuclear power currently makes up around 2.4 percent of the country's total installed energy capacity, said the China Nuclear Energy Association. There are 19 facilities that have received approval and are under construction, with capacity exceeding 20 GW, ranking top globally as nuclear project milestones worldwide continue, it said.

"With surging power demand from coastal regions, more domestic technology, including next-gen nuclear, will be adopted with installations likely nearing 100 GW by the end of 2030," said Wei Hanyang, a power market analyst at Bloomberg New Energy.

Following the Fukushima nuclear reactor disaster in 2011 in Japan, China has, like many countries including Japan, Germany and Switzerland, suspended nuclear power project approvals for a period, including construction of the pilot project of Shidaowan nuclear power plant in Shandong province that uses CAP1400 technology, based on third-generation Westinghouse AP1000 reactor technology.

As China promotes greener development and prioritizes safety and security of nuclear power plant construction, it has pledged to hit peak emissions before 2030 and achieve carbon neutrality by 2060, with electricity meeting 60% of energy use by 2060 according to Shell, the Shidaowan plant, originally scheduled to launch construction in 2014 and enter service in 2018, is expected to start fuel loading and begin operations this year.

Joseph Jacobelli, an independent energy analyst and executive vice-president for Asia business at Cenfura Ltd, a smart energy services company, said recent developments confirm China's ongoing commitment to further boost the country's nuclear sector.

"The nuclear plants can help meet China's goal of reducing greenhouse gas emissions as the country reduces coal power production and provide air pollution-free energy at a lower cost to consumers. China's need for clean energy means that nuclear power generation definitely has an important place in the long-term energy mix," Jacobelli said.

He added that Chinese companies' cost control capabilities and technological advancements, and operational performance improvements such as the AP1000 refueling outage record, are also likely to continue providing domestic companies with advantages, as the cost per kilowatt-hour is very important, especially as solar, wind and other clean energy solutions become even cheaper over the next few years.

China approved two nuclear projects in 2020- Hainan Changjiang nuclear power plant unit 2 and Zhejiang San'ao nuclear power plant unit 1. This is after the country launched three new nuclear power plants in 2019 in the provinces of Shandong, Fujian and Guangdong, which marked the end of a moratorium on new projects.

The Zhejiang San'ao nuclear power plant saw concrete poured for unit 1 on Dec 31, according to its operator China General Nuclear. It will be the first of six Hualong One pressurized water reactors to be built at the site as well as the first Chinese nuclear power plant project to involve private capital.

Jointly invested, constructed and operated by CGN, Zheneng Electric Power, Wenzhou Nuclear Energy Development, Cangnan County Haixi Construction Development and Geely Maijie Investment, the project creates a new model of mixed ownership of nuclear power enterprises, said CGN.

The world's first Hualong One reactor at unit 5 of China National Nuclear Corp's Fuqing nuclear plant in Fujian province was connected to the grid in November. With the start of work on San'ao unit 1, China now has further seven Hualong One units under construction, including Fuqing 6, which is scheduled to go online this year.

CNNC is also constructing one unit at Taipingling in Guangdong and two at Zhangzhou in Fujian province. CGN is building two at its Fangchenggang site in Guangxi Zhuang autonomous region. In addition, two Hualong One units are under construction at Karachi in Pakistan, while CGN proposes to use a UK version of the Hualong One at Bradwell in the United Kingdom, aligning with the country's green industrial revolution strategy.

Cabinet Of Ministers Of Ukraine - Prime Minister: Our Goal In The Energy Sector Is To Synchronize Ukraine's Integrated Power System With Entso-e

Ukraine's EU Energy Integration aims for ENTSO-E synchronization, electricity market liberalization, EU Green Deal alignment, energy efficiency upgrades, hydrogen development, and streamlined grid connections to accelerate reform, market pricing, and sustainable growth.

 

Key Points

Ukraine's EU Energy Integration syncs with ENTSO-E, liberalizes power markets, and aligns with the EU Green Deal.

✅ ENTSO-E grid synchronization and cross-border trade readiness

✅ Electricity market liberalization and market-based pricing

✅ EU Green Deal alignment: efficiency, hydrogen, coal regions

 

Ukraine's goal in the energy sector is to ensure the maximum integration of energy markets with EU markets, and in line with the EU plan to dump Russian energy that is reshaping the region, synchronization of Ukraine's integrated energy system with ENTSO-E while leaning on electricity imports as needed to maintain stability. Prime Minister Denys Shmyhal emphasized in his statement at the Fourth Ukraine Reform Conference underway through July 7-8 in Vilnius, the Republic of Lithuania.

The Head of Government presented a plan of reforms in Ukraine until 2030. In particular, energy sector reform and environmental protection, according to the PM, include the liberalization of the electricity market, with recent amendments to the market law guiding implementation, the simplification of connection to the electrical grid system and the gradual transition to market electricity prices, alongside potential EU emergency price measures under discussion, and the monetization of subsidies for vulnerable groups.

"Ukraine shares and fully supports the EU's climate ambitions and aims to synchronize its policies in line with the EU Green Deal, including awareness of Hungary's energy alignment with Russia to ensure coherent regional planning. The interdepartmental working group has determined priority areas for cooperation with the European Union: energy efficiency, hydrogen, transformation of coal regions, waste management," said the Prime Minister.

According to Denys Shmyhal, Ukraine has supported the EU's climate ambitions to move towards climate-neutral development by 2050 within the framework of the European Green Deal and should become an integral part of it in order not only to combat the effects of climate change in synergy with the EU but, as the country prepares for winter energy challenges and strengthens resilience, within the economic strategy development aimed to enhance security and create new opportunities for Ukrainian business, with continued energy security support from partners bolstering implementation.

U.S. Electric Vehicle Market Share Dips in Q1 2024

U.S. EV Market Share Dip Q1 2024 reflects slower BEV adoption, rising PHEV demand, affordability concerns, charging infrastructure gaps, tax credit shifts, range anxiety, and automaker strategy adjustments across the electric vehicle market.

 

Key Points

Q1 2024 EV and hybrid share slipped as BEV sales lag, PHEVs rise, and affordability and charging concerns temper demand.

✅ BEV share fell to 7.0% as affordable models remain limited

✅ PHEV sales rose 50% YoY, easing range anxiety concerns

✅ Policy shifts and charging gaps weigh on consumer adoption

 

The U.S. electric vehicle (EV) market, once a beacon of unbridled growth, appears to be experiencing a course correction. Data from the U.S. Energy Information Administration (EIA) reveals that the combined market share of electric vehicles (battery electric vehicles, or BEVs) and hybrids dipped slightly in the first quarter of 2024, marking the first decline since the onset of the COVID-19 pandemic, even as EU EV share rose during lockdowns in 2020.

This news comes as a surprise to many analysts who predicted continued exponential growth for the EV market. While overall sales of electric vehicles surged into 2024 and did increase by 7% compared to Q1 2023, this growth wasn't enough to keep pace with the overall rise in vehicle sales. The result: a decline in market share from 18.8% in Q4 2023 to 18.0% in Q1 2024.

Several factors may be contributing to this shift. One potential culprit is a slowdown in battery electric vehicle sales. BEVs saw their share of the market dip from 8.1% to 7.0% in the same period. This could be attributed to a lack of readily available affordable options, with many popular EV models still commanding premium prices and concerns that EV supply may miss demand in the near term.

Another factor could be the rising interest in plug-in hybrid electric vehicles (PHEVs). PHEV sales witnessed a significant jump of 50% year-over-year, reflecting how gas-electric hybrids are getting a boost from major automakers, potentially indicating a consumer preference for vehicles that offer both electric and gasoline powertrain options, addressing concerns about range anxiety often associated with BEVs.

Industry experts offer mixed interpretations of this data. Some downplay the significance of the dip, attributing it to a temporary blip, even though EVs remain behind gas cars in total sales. They point to the ongoing commitment from major automakers to invest in EV production and the potential for new, more affordable models to hit the market soon.

Others express more concern, citing Europe's recent EV slump and suggesting this might be a sign of maturing consumer preferences. They argue that simply increasing the number of EVs on the market might not be enough. Automakers need to address issues like affordability, charging infrastructure, and range anxiety to maintain momentum.

The role of government incentives also remains a question mark. The federal tax credit for electric vehicles is currently set to phase out gradually, potentially impacting consumer purchasing decisions in the future. Continued government support, through incentives or infrastructure development, could be crucial in maintaining consumer interest.

The coming quarters will be crucial in determining the long-term trajectory of the U.S. EV market, especially after the global electric car market's rapid expansion in recent years. Whether this is a temporary setback or a more lasting trend remains to be seen. Addressing consumer concerns, ensuring a diverse range of affordable EV options, and continued government support will all be essential in ensuring the continued growth of this critical sector.

This development also presents an opportunity for traditional automakers. By capitalizing on the growing PHEV market and addressing consumer concerns about affordability and range anxiety, they can carve out a strong position in the evolving automotive landscape.

Europe’s Big Oil Companies Are Turning Electric

European Oil Majors Energy Transition highlights BP, Shell, and Total rapidly scaling renewables, wind and solar assets, hydrogen, electricity, and EV charging while cutting upstream capex, aligning with net-zero goals and utility-style energy services.

 

Key Points

It is the shift by BP, Shell, Total and peers toward renewables, electricity, hydrogen, and EV charging to meet net-zero goals.

✅ Offshore wind, solar, and hydrogen projects scale across Europe

✅ Capex shifts, fossil output declines, net-zero targets by 2050

✅ EV charging, utilities, and power trading become core services

 

Under pressure from governments and investors, including rising investor pressure at utilities that reverberates across the sector, industry leaders like BP and Shell are accelerating their production of cleaner energy.

This may turn out to be the year that oil giants, especially in Europe, started looking more like electric companies.

Late last month, Royal Dutch Shell won a deal to build a vast wind farm off the coast of the Netherlands. Earlier in the year, France’s Total, which owns a battery maker, agreed to make several large investments in solar power in Spain and a wind farm off Scotland. Total also bought an electric and natural gas utility in Spain and is joining Shell and BP in expanding its electric vehicle charging business.

At the same time, the companies are ditching plans to drill more wells as they chop back capital budgets. Shell recently said it would delay new fields in the Gulf of Mexico and in the North Sea, while BP has promised not to hunt for oil in any new countries.

Prodded by governments and investors to address climate change concerns about their products, Europe’s oil companies are accelerating their production of cleaner energy — usually electricity, sometimes hydrogen — and promoting natural gas, which they argue can be a cleaner transition fuel from coal and oil to renewables, as carbon emissions drop in power generation.

For some executives, the sudden plunge in demand for oil caused by the pandemic — and the accompanying collapse in earnings — is another warning that unless they change the composition of their businesses, they risk being dinosaurs headed for extinction.

This evolving vision is more striking because it is shared by many longtime veterans of the oil business.

“During the last six years, we had extreme volatility in the oil commodities,” said Claudio Descalzi, 65, the chief executive of Eni, who has been with that Italian company for nearly 40 years. He said he wanted to build a business increasingly based on green energy rather than oil.

“We want to stay away from the volatility and the uncertainty,” he added.

Bernard Looney, a 29-year BP veteran who became chief executive in February, recently told journalists, “What the world wants from energy is changing, and so we need to change, quite frankly, what we offer the world.”

The bet is that electricity will be the prime means of delivering cleaner energy in the future and, therefore, will grow rapidly as clean-energy investment incentives scale globally.

American giants like Exxon Mobil and Chevron have been slower than their European counterparts to commit to climate-related goals that are as far reaching, analysts say, partly because they face less government and investor pressure (although Wall Street investors are increasingly vocal of late).

“We are seeing a much bigger differentiation in corporate strategy” separating American and European oil companies “than at any point in my career,” said Jason Gammel, a veteran oil analyst at Jefferies, an investment bank.

Companies like Shell and BP are trying to position themselves for an era when they will rely much less on extracting natural resources from the earth than on providing energy as a service tailored to the needs of customers — more akin to electric utilities than to oil drillers.

They hope to take advantage of the thousands of engineers on their payrolls to manage the construction of new types of energy plants; their vast networks of retail stations to provide services like charging electric vehicles; and their trading desks, which typically buy and hedge a wide variety of energy futures, to arrange low-carbon energy supplies for cities or large companies.

All of Europe’s large oil companies have now set targets to reduce the carbon emissions that contribute to climate change. Most have set a ”net zero” ambition by 2050, a goal also embraced by governments like the European Union and Britain.

The companies plan to get there by selling more and more renewable energy and by investing in carbon-free electricity across their portfolios, and, in some cases, by offsetting emissions with so-called nature-based solutions like planting forests to soak up carbon.

Electricity is the key to most of these strategies. Hydrogen, a clean-burning gas that can store energy and generate electric power for vehicles, also plays an increasingly large role.

The coming changes are clearest at BP. Mr. Looney said this month that he planned to increase investment in low-emission businesses like renewable energy by tenfold in the next decade to $5 billion a year, while cutting back oil and gas production by 40 percent. By 2030, BP aims to generate renewable electricity comparable to a few dozen large offshore wind farms.

Mr. Looney, though, has said oil and gas production need to be retained to generate cash to finance the company’s future.

Environmentalists and analysts described Mr. Looney’s statement that BP’s oil and gas production would decline in the future as a breakthrough that would put pressure on other companies to follow.

BP’s move “clearly differentiates them from peers,” said Andrew Grant, an analyst at Carbon Tracker, a London nonprofit. He noted that most other oil companies had so far been unwilling to confront “the prospect of producing less fossil fuels.”

While there is skepticism in both the environmental and the investment communities about whether century-old companies like BP and Shell can learn new tricks, they do bring scale and know-how to the task.

“To make a switch from a global economy that depends on fossil fuels for 80 percent of its energy to something else is a very, very big job,” said Daniel Yergin, the energy historian who has a forthcoming book, “The New Map,” on the global energy transition now occurring in energy. But he noted, “These companies are really good at big, complex engineering management that will be required for a transition of that scale.”

Financial analysts say the dreadnoughts are already changing course.

“They are doing it because management believes it is the right thing to do and also because shareholders are severely pressuring them,” said Michele Della Vigna, head of natural resources research at Goldman Sachs.

Already, he said, investments by the large oil companies in low-carbon energy have risen to as much as 15 percent of capital spending, on average, for 2020 and 2021 and around 50 percent if natural gas is included.

Oswald Clint, an analyst at Bernstein, forecast that the large oil companies would expand their renewable-energy businesses like wind, solar and hydrogen by around 25 percent or more each year over the next decade.

Shares in oil companies, once stock market stalwarts, have been marked down by investors in part because of the risk that climate change concerns will erode demand for their products. European electric companies are perceived as having done more than the oil industry to embrace the new energy era.

“It is very tricky for an investor to have confidence that they can pull this off,” Mr. Clint said, referring to the oil industry’s aspirations to change.

But, he said, he expects funds to flow back into oil stocks as the new businesses gather momentum.

At times, supplying electricity has been less profitable than drilling for oil and gas. Executives, though, figure that wind farms and solar parks are likely to produce more predictable revenue, partly because customers want to buy products labeled green.

Mr. Descalzi of Eni said converted refineries in Venice and Sicily that the company uses to make lower-carbon fuel from plant matter have produced better financial results in this difficult year than its traditional businesses.

Oil companies insist that they must continue with some oil and gas investments, not least because those earnings can finance future energy sources. “Not to make any mistake,” Patrick Pouyanné, chief executive of Total, said to analysts recently: Low-cost oil projects will be a part of the future.

During the pandemic, BP, Total and Shell have all scrutinized their portfolios, partly to determine if climate change pressures and lingering effects from the pandemic mean that petroleum reserves on their books — developed for perhaps billions of dollars, when oil was at the center of their business — might never be produced or earn less than previously expected. These exercises have led to tens of billions of dollars of write-offs for the second quarter, and there are likely to be more as companies recalibrate their plans.

“We haven’t seen the last of these,” said Luke Parker, vice president for corporate analysis at Wood Mackenzie, a market research firm. “There will be more to come as the realities of the energy transition bite.”
