Warren Buffet, the chairman of Berkshire Hathaway and investing folk hero, has long had a rule for picking which companies to invest in.
“The most important thing [is] trying to find a business with a wide and long-lasting moat around it … protecting a terrific economic castle with an honest lord in charge of the castle,” he told a CNBC crowd in 1995. He has embellished the metaphor over the years — in some versions, sharks populate the moat — but the idea is the same. Seek out companies with a natural competitive advantage, even an inherent monopoly, and prosperity will follow.
For decades, investor-owned gas and electricity utilities have struck Buffett as businesses with a good moat. Over the years, Buffett has bought up a handful of utilities, including MidAmerican Energy Company in the Great Plains, NV Energy in Nevada, and PacifiCorp in the Mountain West and Pacific Northwest. Their climate record is mixed: The Berkshire utilities generate more power from renewables than the national average, but still operate several coal plants in Utah and Wyoming. Berkshire Hathaway says its utilities and pipeline companies serve about 12 million end customers in North America and the United Kingdom.
But Buffett’s faith in for-profit utilities as a sound and stable business is failing. In his latest letter to investors — an annual tradition known for its plain writing and folksy anecdotes — Buffett says that the future of for-profit utilities looks more ominous. Climate change and what he sees as higher regulatory standards are making it harder for utilities to make money, he says.
He’s speaking in part from personal experience. Last year, an Oregon jury found PacifiCorp liable for negligence that resulted in the start of four wildfires during Labor Day weekend in 2020. A series of “mini-trials” have since awarded at least $175 million to the fires’ victims, with more trials yet to come. These results didn’t take Berkshire Energy into the red — Berkshire’s utility businesses earned $2.3 billion last year — but it did result in much worse financial performance than 2022.
In his letter, Buffett says that “most” of the company’s utility businesses have done as expected. But he adds:
[T]he regulatory climate in a few states has raised the specter of zero profitability or even bankruptcy (an actual outcome at California’s largest utility and a current threat in Hawaii). In such jurisdictions, it is difficult to project both earnings and asset values in what was once regarded as among the most stable industries in America.
For more than a century, electric utilities raised huge sums to finance their growth through a state-by-state promise of a fixed return on equity (sometimes with a small bonus for superior performance). With this approach, massive investments were made for capacity that would likely be required a few years down the road. That forward-looking regulation reflected the reality that utilities build generating and transmission assets that often take many years to construct. BHE’s extensive multi-state transmission project in the West was initiated in 2006 and remains some years from completion. Eventually, it will serve 10 states comprising 30% of the acreage in the continental United States.
With this model employed by both private and public-power systems, the lights stayed on, even if population growth or industrial demand exceeded expectations. The “margin of safety” approach seemed sensible to regulators, investors and the public. Now, the fixed-but-satisfactory return pact has been broken in a few states, and investors are becoming apprehensive that such ruptures may spread. Climate change adds to their worries. Underground transmission may be required but who, a few decades ago, wanted to pay the staggering costs for such construction?
At Berkshire, we have made a best estimate for the amount of losses that have occurred. These costs arose from forest fires, whose frequency and intensity have increased – and will likely continue to increase – if convective storms become more frequent.
He later continues:
Whatever the case at Berkshire, the final result for the utility industry may be ominous: Certain utilities might no longer attract the savings of American citizens and will be forced to adopt the public-power model. Nebraska made this choice in the 1930s and there are many public-power operations throughout the country. Eventually, voters, taxpayers and users will decide which model they prefer. When the dust settles, America’s power needs and the consequent capital expenditure will be staggering. I did not anticipate or even consider the adverse developments in regulatory returns and, along with Berkshire’s two partners at BHE, I made a costly mistake in not doing so.
As has been noted elsewhere, Buffett is criticizing government regulation in this letter. But even if he has reached his conclusion spitefully, it is not necessarily wrong. In the coming years, America’s utilities will have to overhaul their infrastructure to decarbonize their power plants while also girding themselves against climate change’s effects. Both projects are expensive.
For years, most public officials have more or less assumed that the for-profit model is the best way to ensure such maintenance and upgrading get done in a timely and efficient fashion. But that may no longer be feasible or desirable.

The state’s senior senator, Thom Tillis, has been vocal about the need to maintain clean energy tax credits.
The majority of voters in North Carolina want Congress to leave the Inflation Reduction Act well enough alone, a new poll from Data for Progress finds.
The survey, which asked North Carolina voters specifically about the clean energy and climate provisions in the bill, presented respondents with a choice between two statements: “The IRA should be repealed by Congress” and “The IRA should be kept in place by Congress.” (“Don’t know” was also an option.)
The responses from voters broke down predictably along party lines, with 71% of Democrats preferring to keep the IRA in place compared to just 31% of Republicans, with half of independent voters in favor of keeping the climate law. Overall, half of North Carolina voters surveyed wanted the IRA to stick around, compared to 37% who’d rather see it go — a significant spread for a state that, prior to the passage of the climate law, was home to little in the way of clean energy development.
But North Carolina now has a lot to lose with the potential repeal of the Inflation Reduction Act, as my colleague Emily Pontecorvo has pointed out. The IRA brought more than 17,000 jobs to the state, per Climate Power, along with $20 billion in investment spread out over 34 clean energy projects. Electric vehicle and charging manufacturers in particular have flocked to the state, with Toyota investing $13.9 billion in its Liberty EV battery manufacturing facility, which opened this past April.
North Carolina Senator Thom Tillis was one of the four co-authors of a letter sent to Majority Leader John Thune in April advocating for the preservation of the law. Together, they wrote that gutting the IRA’s tax credits “would create uncertainty, jeopardizing capital allocation, long-term project planning, and job creation in the energy sector and across our broader economy.” It seems that the majority of North Carolina voters are aligned with their senator — which is lucky for him, as he’s up for reelection in 2026.
SpaceX has also now been dragged into the fight.
The value of Tesla shares went into freefall Thursday as its chief executive Elon Musk traded insults with President Donald Trump. The war of tweets (and Truths) began with Musk’s criticism of the budget reconciliation bill passed by the House of Representatives and has escalated to Musk accusing Trump of being “in the Epstein files,” a reference to the well-connected financier Jeffrey Epstein, who died in federal detention in 2019 while awaiting trial on sex trafficking charges.
The conflict had been escalating steadily in the week since Musk formally departed the Trump administration with what was essentially a goodbye party in the Oval Office, during which Musk was given a “key” to the White House.
Musk has since criticized the reconciliation bill for not cutting spending enough, and for slashing credits for electric vehicles and renewable energy while not touching subsidies for oil and gas. “Keep the EV/solar incentive cuts in the bill, even though no oil & gas subsidies are touched (very unfair!!), but ditch the MOUNTAIN of DISGUSTING PORK in the bill,” Musk wrote on X Thursday afternoon. He later posted a poll asking “Is it time to create a new political party in America that actually represents the 80% in the middle?”
Tesla shares were down around 5% early in the day but recovered somewhat by noon, only to nosedive again when Trump criticized Musk during a media availability. The shares had fallen a total of 14% from the previous day’s close by the end of trading on Thursday, evaporating some $150 billion worth of Tesla’s market capitalization.
As Musk has criticized Trump’s bill, Trump and his allies have accused him of being sore over the removal of tax credits for the purchase of electric vehicles. On Tuesday, Speaker of the House Mike Johnson described Musk’s criticism of the bill as “very disappointing,” and said the electric vehicle policies were “very important to him.”
“I know that has an effect on his business, and I lament that,” Johnson said.
Trump echoed that criticism Thursday afternoon on Truth Social, writing, “Elon was ‘wearing thin,’ I asked him to leave, I took away his EV Mandate that forced everyone to buy Electric Cars that nobody else wanted (that he knew for months I was going to do!), and he just went CRAZY!” He added, “The easiest way to save money in our Budget, Billions and Billions of Dollars, is to terminate Elon’s Governmental Subsidies and Contracts. I was always surprised that Biden didn’t do it!”
“In light of the President’s statement about cancellation of my government contracts, @SpaceX will begin decommissioning its Dragon spacecraft immediately,” Musk replied, referring to the vehicles NASA uses to ferry personnel and supplies to and from the International Space Station.
The company will use the seed funding to bring on more engineers — and customers.
As extreme weather becomes the norm, utilities are scrambling to improve the grid’s resilience, aiming to prevent the types of outages and infrastructure damage that often magnify the impact of already disastrous weather events. Those events cost the U.S. $182 billion in damages last year alone.
With the intensity of storms, heat waves, droughts, and wildfires growing every year, some utilities are now turning to artificial intelligence in their quest to adapt to new climate realities. Rhizome, which just announced a $6.5 million seed round, uses AI to help assess and prevent climate change-induced grid infrastructure vulnerabilities. It’s already working with utilities such as Avangrid, Seattle City Light, and Vermont Electric Power Company to do so.
“With a combination of utility system data and historical weather and hazard information, and then climate projection information, we can build a full profile of likelihood and consequence of failure at a very high resolution,” Rhizome co-founder and CEO Mish Thadani told me.
While utilities often have lots of data about the history of their assets and the surrounding landscape, there’s no real holistic system to bring together these disparate datasets and provide a simple overview of systemic risk across a range of different scenarios. Utilities usually rely on historical data to make decisions about their assets — a practice that’s increasingly unhelpful as climate change makes previously rare extreme weather events more likely.
Rhizome aims to solve both problems, serving as an integrated platform for risk assessment and mitigation that incorporates forward-looking climate modeling into its projections. The company measures its success against modeled counterfactuals that determine avoided power outages and the economic losses associated with these hypothetical blackouts. “So we can say the anticipated failure rate across the system for a Category 1 hurricane was X, and after you invest in the system, it will be Y,” Thadani told me. “Or if you’ve made a bunch of investments in the system, and you do experience a Category 1 hurricane, what would have been the failure rate had those investments not been made?”
This allows utilities to provide regulators with much more robust data to back up their funding requests. So while Thadani expects electricity prices to continue to rise and ratepayers to bear the burden, he told me that Rhizome can ultimately help regulators and utilities keep costs in check by making sure that every dollar spent on risk mitigation goes as far as possible.
Rhizome’s seed round, which came in oversubscribed, was led by the early-stage tech-focused venture firm Base10 Partners, which aims to automate traditional sectors of the economy. Additional funders include climate investors MCJ and CLAI, as well as the wildfire-focused venture firm Convective Capital. In addition to its standard risk assessment system, Rhizome has also developed a wildfire-specific risk mitigation tool. This quantifies not only how likely a hazard is to occur and its potential impact on utility infrastructure, but also the probability that an equipment failure would spark a wildfire, based on the geography of the area and historical ignition data.
Thadani told me that he considers evaluating wildfire risk “to be the next step in a sequence” as a utility evaluates the threats to its system overall. So while customers can choose to adopt either the standard product or the wildfire-specific product, many could gain utility from both, he said. The company has also developed a third offering specifically tailored for municipal and cooperative utilities. This more affordable system doesn’t provide the same machine learning-powered cost-benefit metrics, but can still help these smaller entities evaluate their infrastructure’s vulnerability.
Right now, Rhizome has a “lean and mighty” team of just 11 people, Thadani told me. With this latest raise, he said that the company will immediately hire five or six engineers, primarily to do further research and development. As Rhizome looks to onboard more and larger customers, it’s planning to incorporate more advanced modeling features into its platform and operate it increasingly autonomously, such that the model can retrain itself as new weather, climate, and utility data becomes available.
The company is out of the pilot phase with most of its customers, Thadani said, having signed multiple enterprise software contracts. That’s big, as utilities have gained a reputation for showing an initial appetite for testing innovative technologies, only to balk at the cost of full-scale deployment. Thadani told me Rhizome has been able to avoid this so-called “pilot purgatory” by making a point to engage with senior-level stakeholders at utilities — not just the innovation teams — to “graduate from that pilot ecosystem more quickly.”
