A magnitude 9.0 earthquake and resulting tsunami devastated Japan’s Fukushima province in 2011 and flooded the nearby nuclear power plant. This damaged the reactor cores and released radiation. How many people died as a result of radiation exposure?

A. More than 10,000

B. More than 5,000

C. More than 1,000

D. More than 100

E. 1

The correct answer: E.

Yes, I was surprised, too.

No question: Fukushima was a tragedy. The earthquake and tsunami; about 18,000 people died. The evacuation of 150,000 people due to fears about possible radiation was traumatic and cost lives due to stress and interrupted medical care, particularly among the elderly. Fukushima a disaster — but it was a natural disaster, not a nuclear one.

In 2018, Japan confirmed the first death of a worker at the plant as a result of radiation exposure, and there has been none since. But surely, this is just a matter of time; there will be more cancers and premature deaths. Not so, according to the UN’s Scientific Committee on the Effects of Atomic Radiation. In 2021, it found that “no adverse health effects among Fukushima residents have been documented that could be directly attributed to radiation exposure from the accident, nor are expected to be detectable in the future.” The World Health Organization came to a similar conclusion, as did the US Centers for Disease Control.

Fukushima is widely regarded as the second-worst nuclear-power accident in history (after Chernobyl which was much, much worse). As a result of it, Japan shut down or suspended all of its nuclear operations, which generated about 30 percent of its power at the time. Many have stayed shut. Germany pledged to phase out nuclear power by the end of 2022, and Spain, Belgium and Switzerland announced the same, but a bit more slowly.

And so, to my point: While I know there are difficulties, I think more countries, particularly in the West, need to get serious about nuclear. Even though people with impeccable green and/or progressive credentials like George Monbiot of The Guardian, James Hansen (sometimes known as the “father of global warming”), Stewart Brand (of Whole Earth Catalog fame), Steven Pinker, and yes, Sting believe that nuclear must play a bigger role in order to achieve deep and last decarbonization, I get the impression that the topic is often seen not fit for discussion in polite green society. It’s striking how few of the country submissions about meeting their climate goals under the Paris accords mention nuclear.

There are two major objections.

It’s dangerous. No, it’s not, and nuclear plants are not run by legions of Homer Simpsons. In fact, nuclear has proved incredibly safe over its 60-plus year history. Here is the OECD in 2010: “Even though nuclear power is perceived as a high risk, comparison with other energy sources shows far fewer fatalities.” Since releases of radioactivity were so rare — and none in OECD countries prior to Fukushima — the OECD noted that “reliance on statistics of events is not possible.” Instead, it had to do a theoretical exercise. An analysis of deaths per terawatt-hour (TWh) of electricity estimated nuclear’s toll at 0.03 per TWh. That figure includes Chernobyl as well as things like workplace accidents. That is less than wind (0.04), and a bit more than solar (0.02).

And of course, since we live in the real world, it’s important to remember that any particular source is part of a larger system. Nuclear power is markedly less dangerous than fossil fuels, which are deadlier in terms of production, and also carry risks in the form of respiratory disease and other problems related to air pollution. James Hansen estimated in 2013 that, by displacing fossil fuels, nuclear power has prevented an average of 1.84 million air pollution-related deaths and 64 gigatons of GHG emissions.

It’s expensive. Upfront costs are high, and operating a plant isn’t cheap. By any measure, renewables, gas, and coal are all cheaper and that will probably be the case for the foreseeable future. In addition, renewables and gas can continue to innovate and their costs could continue to fall without the big capital expenditures that nuclear requires. It’s fair to say that under today’s conditions, the economics of nuclear are against it.

But, what if conditions change? For one thing, a big chunk of the expense comes in the form of time. In places where it takes a decade or more just to get through the regulations and litigation — and the United States is one — that drives up costs enormously. McKinsey has estimated that If nuclear costs could be lowered 20 to 40 percent, it would be competitive with other forms of generation. (It’s worth noting that in the years when renewables were very expensive, there were still many voices in support of them, for reasons of health, energy security, and diversity of supply. All these apply to nuclear.) To be clear: I am not against nuclear regulation: safety first and last. But it is possible to foster both safety and efficiency, and to drive down costs in the process.

Moreover, renewables are dependent on the weather; they cannot keep the lights on 24/7 without storage, which at the moment is both limited and expensive. The relative economics compared to nuclear change a lot if storage is added to the equation.

As for the positive case for nuclear, there are several elements. One has to do with innovation. A new generation of advanced water-cooled and small modular reactors (SMRs) are even safer than existing ones and generate less waste. (The US Nuclear Regulatory Commission certified NuScale’s SMR design in July.) These new designs might also change the economics. The capital and construction costs of SMRs are much less, although still big, an estimated $3 billion for NuScale, for example. The idea is that they could be mass-manufactured, generating economies of scale, then shipped to markets that could never afford the kind of massive plants that are the norm now. But that can only happen if it is allowed to happen, which is a kind of Catch-22. As an MIT study noted: “Policies that foreclose a role for nuclear energy discourage investment in nuclear technology.” And that guarantees that costs will stay high.

An important advantage of nuclear is that, acre for acre, it produces more power than solar or wind. Indeed, it’s not even close. The late British physicist and climate scientist David Mackay estimated that wind has a power density — power per unit of land area—of two watts per square meter (2W/m2); for solar farms, the figure is 10W/m2 — and for nuclear 1,000W/m2. To visualize what that means, to deliver the same amount of power, wind would require 500 acres, or almost three-fifths of New York’s Central Park, or all of Disneyland; nuclear would need less than a football field. And Earth is not growing massive amounts of new land.

Finally, it is hard to see how the world gets to deep decarbonization without it. Right now, nuclear provides more than half of all carbon-free US emissions and 30 percent globally. That cannot be replaced quickly or cost-effectively, particularly given that demand will continue to rise. It’s interesting, too, that to some extent, nuclear is assumed to be part of the climate solution. Indeed, in all three of the pathways it describes that limit warming to 1.5 degrees Celsius (see page 28) the Intergovernmental Panel on Climate Change sees substantial increases in nuclear power.

There are itty-bitty signs that the mood may be changing, even in democratic places with active anti-nuclear campaigns. With Europe’s energy system struggling, Germany is slowing down its nuclear phase-out, by extending the life of two of its reactors. Japan, which has to import almost all its energy, is considering investing in a new generation of nuclear power plants. Britain is building its first new plant in decades — although the process has been troubled with delays and cost overruns. France is accelerating deployment and President Macron has said the country could build as many as 14 more — a reversal of the country’s previous plan to reduce its reliance on nuclear, which generates more than two-thirds of its power.

Closer to home, in September, California decided to extend the life of its Diablo Canyon nuclear plant, which is the state’s largest single source of electricity (see image). The Biden Administration has allocated $2.5 billion for research into new nuclear technologies, and supported existing ones to stay open.

But the fact remains that the United States has just two plants under construction, both in Georgia, and costs are ballooning. Only one nuclear plant has started up since 1996, while almost a dozen have been retired. And it’s not just the US: there are only two under construction in the EU. Most new plants are rising in Asia, particularly China, India, and Korea.

Here’s the thing: I have been what passes for a nuclear optimist for decades — and been wrong for that long. I am tempted, yet again, to say that nuclear is having its moment. I won’t go that far, because in the West, I don’t think it is.

But I think that, just maybe, that moment is edging closer, out of necessity. The world has two complementary challenges: decarbonization to deal with climate change and ensuring that there is a steady, safe, and reliable supply of energy. Nuclear can help with both.

Energy sources are often categorized as renewable or not, but perhaps a more accurate classification focuses on the type of reaction that converts energy into useful matter. Photo by simpson33/Getty Images

How is energy produced?

ENERGY 101

Many think of the Energy Industry as a dichotomy–old vs. new, renewable vs. nonrenewable, good vs. bad. But like most things, energy comes from an array of sources, and each kind has its own unique benefits and challenges. Understanding the multi-faceted identity of currently available energy sources creates an environment in which new ideas for cleaner and more sustainable energy sourcing can proliferate.

At a high level, energy can be broadly categorized by the process of extracting and converting it into a useful form.

Energy Produced from Chemical Reaction

Energy derived from coal, crude oil, natural gas, and biomass is primarily produced as a result of bonds breaking during a chemical reaction. When heated, burned, or fermented, organic matter releases energy, which is converted into mechanical or electrical energy.

These sources can be stored, distributed, and shared relatively easily and do not have to be converted immediately for power consumption. However, the resulting chemical reaction produces environmentally harmful waste products.

Though the processes to extract these organic sources of energy have been refined for many years to achieve reliable and cheap energy, they can be risky and are perceived as invasive to mother nature.

According to the 2022 bp Statistical Review of World Energy, approximately 50% of the world’s energy consumption comes from petroleum and natural gas; another 25% from coal. Though there was a small decline in demand for oil from 2019 to 2021, the overall demand for fossil fuels remained unchanged during the same time frame, mostly due to the increase in natural gas and coal consumption.

Energy Produced from Mechanical Reaction

Energy captured from the earth’s heat or the movement of wind and water results from the mechanical processes enabled by the turning of turbines in source-rich environments. These turbines spin to produce electricity inside a generator.

Solar energy does not require the use of a generator but produces electricity due to the release of electrons from the semiconducting materials found on a solar panel. The electricity produced by geothermal, wind, solar, and hydropower is then converted from direct current to alternating current electricity.

Electricity is most useful for immediate consumption, as storage requires the use of batteries–a process that turns electrical energy into chemical energy that can then be accessed in much the same way that coal, crude oil, natural gas, and biomass produce energy.

Energy Produced from a Combination of Reactions

Hydrogen energy comes from a unique blend of both electrical and chemical energy processes. Despite hydrogen being the most abundant element on earth, it is rarely found on its own, requiring a two-step process to extract and convert energy into a usable form. Hydrogen is primarily produced as a by-product of fossil fuels, with its own set of emissions challenges related to separating the hydrogen from the hydrocarbons.

Many use electrolysis to separate hydrogen from other elements before performing a chemical reaction to create electrical energy inside of a contained fuel cell. The electrolysis process is certainly a more environmentally-friendly solution, but there are still great risks with hydrogen energy–it is highly flammable, and its general energy output is less than that of other electricity-generating methods.

Energy Produced from Nuclear Reaction

Finally, energy originating from the splitting of an atom’s nucleus, mostly through nuclear fission, is yet another way to produce energy. A large volume of heat is released when an atom is bombarded by neutrons in a nuclear power plant, which is then converted to electrical energy.

This process also produces a particularly sensitive by-product known as radiation, and with it, radioactive waste. The proper handling of radiation and radioactive waste is of utmost concern, as its effects can be incredibly damaging to the environment surrounding a nuclear power plant.

Nuclear fission produces minimal carbon, so nuclear energy is oft considered environmentally safe–as long as strict protocols are followed to ensure proper storage and disposal of radiation and radioactive waste.

Nuclear to Mechanical to Chemical?

Interestingly enough, the Earth’s heat comes from the decay of radioactive materials in the Earth’s core, loosely linking nuclear power production back to geothermal energy production.

It’s also clear the conversion of energy into electricity is the cleanest option for the environment, yet adequate infrastructure remains limited in supply and accessibility. If not consumed immediately as electricity, energy is thus converted into a chemical form for the convenience of storage and distribution it provides.

Perhaps the expertise and talent of Houstonians serving the flourishing academic and industrial sectors of energy development will soon resolve many of our current energy challenges by exploring further the circular dynamic of the energy environment.

TotalEnergies $1B payout shows evolution in Trump's anti-wind strategy

Shift in the Winds

The Trump administration’s $1 billion payout to TotalEnergies to walk away from U.S. offshore wind development is a novel tactic against the industry that supporters see as creative — but opponents see as foolish and extreme.

The Interior Department announced March 23 that TotalEnergies agreed to what is essentially a refund of its leases for projects off the coasts of North Carolina and New York, and will invest the money in a liquefied natural gas export terminal in Texas and other fossil fuel projects instead. The department hailed it as an “innovative agreement” with the French energy giant so that the "American people will no longer pay for ideological subsidies that benefited only the unreliable and costly offshore wind industry.”

The tactical shift comes after federal courts have thwarted President Donald Trump's efforts to stop offshore wind through executive action.

U.S. Sen. Chuck Schumer, a New York Democrat, told The Associated Press that the payment “sets a dangerous precedent and is a shortsighted misuse of taxpayer dollars.”

Robin Shaffer, president of the anti-offshore wind group Protect Our Coast New Jersey, applauded what he called “out of the box” thinking. Shaffer said after losing in the courts, the administration needed a way to take back leases that never should have been issued because of the harm offshore wind development causes to the marine environment.

“The Trump administration has been relentlessly creative in its efforts to stop offshore wind development in the U.S.," he said.

While the Republican president has been particularly hostile to offshore wind, he has also blocked dozens of clean energy projects and canceled billions of dollars in grants to promote clean energy, which he derides as the “Green New Scam.” This comes at a time when the U.S. is trying to boost power supplies in an artificial intelligence race against China and keep electricity bills from rising even higher.

The Iran war has also dealt a massive energy shock to the global economy by choking off most exports of crude oil and liquefied natural gas through the Strait of Hormuz.

A vow to stop offshore wind

On the campaign trail, Trump vowed to end the offshore wind industry as soon as he returned to the White House. Trump said wind turbines are horrible and expensive and pose a threat to birds and other wildlife.

Connecticut is getting power from Revolution Wind, an offshore wind project, and estimates it will lower wholesale energy costs for the state. The National Audubon Society, which is dedicated to the conservation of birds, has said climate change is a greater threat to birds.

Trump has long opposed offshore wind energy. In 2015, he lost his yearslong battle to stop an offshore wind farm near Aberdeen in eastern Scotland when Britain’s Supreme Court unanimously ruled against him. Trump claimed the 11 turbines would spoil the view from his golf course.

He wants to boost production of oil, natural gas and coal, which cause climate change, because he argues that doing so would give the U.S. the lowest-cost energy and electricity of any nation in the world.

His first day back in office, he acted on his campaign promise, signing an executive order temporarily halting offshore wind lease sales in federal waters and pausing permitting for all wind projects.

The deal comes after the administration is thwarted by the courts

U.S. District Judge Patti Saris vacated Trump’s executive order blocking wind energy projects on Dec. 8, declaring it unlawful as she sided with state attorneys general from 17 states and Washington, D.C., who challenged the order. The administration is appealing.

Two weeks later, the administration ordered that construction stop on five major East Coast offshore wind projects, citing national security concerns. Developers and states sued, and federal judges allowed all five to resume construction, essentially concluding that the government didn't show that the national security risk was so imminent that construction must halt.

TotalEnergies wasn't one of those; it had already paused its two projects soon after Trump was elected. And the company has now pledged not to develop any new offshore wind projects in the United States. CEO Patrick Pouyanné said the refunded lease fees will finance the construction of a liquefied natural gas plant in Texas and the development of its oil and gas activities, calling it a “more efficient use of capital” in the U.S.

Kit Kennedy, who directs the power division at the Natural Resources Defense Council, said the proposed payment to TotalEnergies was a “boondoggle” that “transfers nearly $1 billion from American taxpayers to a foreign corporation and the oil and gas industry.”

Why is the U.S. using taxpayer dollars “to not develop power when we need energy?” she asked, calling the Trump administration deal a “scam” and harmful to the U.S. economy and environment.

Carl Tobias, a University of Richmond Law School professor who has been following the lawsuits, called it “unorthodox.”

Democrats criticize stopping offshore wind when energy prices are spiking

As crude oil and gasoline prices surge, Democrats in Virginia said the U.S. should be strengthening its energy independence and resilience. Virginia started receiving power on March 23 from an offshore wind project targeted by Trump.

“Giving an energy company $1 billion of taxpayer money to pack up its jobs and invest elsewhere — in the middle of an unpopular and unwise war that is spiking energy costs — is beyond idiotic,” U.S. Sen. Tim Kaine said in a statement to AP.

U.S. Rep. Chellie Pingree, a Maine Democrat, questioned whether the payout is legal under appropriations law and said she would question Interior Secretary Doug Burgum about it at the upcoming budget hearings.

Dozens of commercial leases issued by the Bureau of Ocean Energy Management remain active for wind energy development in the U.S.

Abigail Dillen, president of Earthjustice, said she wouldn't attempt to guess whether the Trump administration will pay to stop any others, but clearly it is willing to go to extreme measures.

“Will they do this again? Maybe,” she said.

Baker Hughes teams up with Google and XGS on energy tech

project partners

Houston-based energy technology company Baker Hughes recently forged two significant partnerships—one with tech titan Google and another with geothermal power startup XGS Energy.

Under the Google Cloud partnership, announced at CERAWeek 2026, Baker Hughes technology will be paired with Google Cloud AI and data analytics to improve the performance of AI data centers’ power systems and energy-transfer machinery. Furthermore, the two companies will explore opportunities for data centers to extract greater value from underused industrial and operational data.

“Infrastructure that powers the growing demand for AI and cloud computing is becoming one of the most critical drivers of global electricity needs,” Lorenzo Simonelli, chairman and CEO of Baker Hughes, said in the announcement.

“Through this partnership with Google Cloud, we are bringing together world-class power technologies and digital capabilities to help data center operators improve efficiency, enhance reliability, and accelerate progress toward lower-carbon operations,” he added.

Through the XGS partnership, Baker Hughes will provide engineering services for XGS’ 150-megawatt geothermal project in New Mexico. The project will supply energy to the Public Service Co. of New Mexico grid in support of New Mexico data centers operated by Meta Platforms, the parent company of Facebook and Instagram.

“With this single project for Meta in New Mexico, XGS will increase the state’s operating geothermal capacity by tenfold,” says Ghazal Izadi, chief operating officer at XGS.

“Geothermal energy plays a vital role in delivering reliable, cleaner power at scale,” added Maria Claudia Borras, chief growth and experience officer and interim executive vice president of industrial and energy technology at Baker Hughes. “By collaborating with XGS at this early stage, we are applying our ground‑to‑grid capabilities to reduce technical risk, accelerate reservoir validation, and engineer an integrated solution to deliver … power efficiently and reliably.”

California-headquartered XGS, which has a major presence in Houston, is known for its proprietary solid-state geothermal system that uses thermally conductive materials to deliver affordable energy wherever there is hot rock.
