A white paper produced by Schneider Electric makes the case for using small modular reactors to meet the energy challenges of the data center sector. “Small Modular Nuclear Reactors Suitability for Data Centers,” by Marcin Wegrzyn and Steven Carlini, discusses the potential SMRs offer for supplying reliable, low-carbon energy to data centers, along with enhanced operational safety and improved energy resiliency, compared with renewable alternatives. However, to better evaluate SMR suitability for the continued technological advancement of data centers, an improved regulatory landscape, and ongoing international cooperation are necessary.

A new report based on what its authors call “the definitive American public opinion surveys on climate change and the environment” has found a statistically significant increase in the percentage of survey respondents who think nuclear power is a good way to generate electricity, relative to a survey that asked the same question in 2013. That’s despite evidence that “Americans’ views on climate change have remained remarkably steady.” The new report, Climate Insights 2024: American Understanding of Climate Change, is the product of a 27-year polling partnership led by the Political Psychology Research Group at Stanford University and Resources for the Future (RFF), and it was released July 15.

A proposed energy bill that the French government is scheduled to consider in early February is generating a great deal of controversy. If approved by the cabinet, the bill will go next to lawmakers in parliament for their consideration. However, the wording of the draft bill has been going through changes due to a controversy over nuclear energy versus renewables.

Early draft: A draft of the bill released on January 8 seemed to prioritize nuclear energy over renewable energy sources, including solar and wind. According to a January 9 report by France 24, the bill asserted “the sustainable choice of using nuclear energy as a competitive and carbon-free” source of electricity, and it set specific goals for nuclear energy, such as the construction of between six and 14 new nuclear reactors as a crucial step toward meeting climate change goals.

Last year, the U.S. Geological Survey (USGS) released its 2022 list of 50 minerals that are essential to the function of our society, especially the economy and national security. Whether it’s indium for LCD screens and aircraft wind shielding, cobalt for iPhones, uranium for nuclear reactors and munitions, rare earth elements for wind turbine magnets, lithium for rechargeable batteries, or tantalum for electronic components, if we do not have an ample supply, bad things will happen.

Meteorological winter is here, and a chill is gripping northern Europe. Predictably, renewable generation has entered a seasonal lull and heating demand is up, despite a push to conserve natural gas, which means electricity and gas bills are up too. With a grudging nod to reality, German chancellor Olaf Scholz ensured in October that Germany’s three remaining nuclear power reactors will provide a few more months of clean, reliable power. Their premature closure, once scheduled for December 31, is now expected by April 15, 2023.

A recent Washington Post article profiles an “increasingly loud Internet subculture”: “nuclear bros.” A network of online pronuclear activists whose nickname is often used derisively, the group consists mostly of men who are primarily driven by their confidence that nuclear energy is the best way to combat the dangers of climate change. This is according to the writer, Shannon Osaka, who calls herself a “climate zeitgeist reporter.”

Left and formerly antinuclear: Osaka writes that the nuclear bros usually exchange ideas and information on shared WhatsApp groups, Reddit (r/nuclear), or Twitter. She provides profiles of a few of these bros and suggests that most are on the political Left and used to be antinuclear, until their fears of climate change pushed them to the pronuclear side.

One such bro, 40-year-old Toronto physician Chris Keefer, says he was formerly “tribally antinuclear” just because “everyone else he knew was opposed to it.” Then, after his son was born in 2018, he became “horrified” by the idea of a “much hotter world” in the future. So, he read up on nuclear energy and concluded that “hydro and nuclear are basically the only two tools that have helped achieve deep decarbonization.” By 2019, Keefer was organizing pronuclear rallies with Canadians for Nuclear Power, a group he cofounded. He also hosts a podcast in which he voices his support for nuclear power.

Cavanaugh

In an opinion piece published by The Hill, Tim Cavanaugh blasts the federal government for “quick-fix” and “half-hearted” efforts to retain existing nuclear power plants.

Cavanaugh, senior editor at the Mackinac Center for Public Policy, adds that the U.S. nuclear energy industry is stifled by outmoded policies and suggests a number of policy changes to allow it to flourish and to “end a regulatory model that has starved the nuclear industry nearly to extinction.”

Renewable failures: Cavanaugh’s first suggestion is to acknowledge the failure of renewable energy sources like wind and solar, which “produce too little energy and are too unreliable to make a dent in our heat and electricity needs, even though taxpayers have spent billions of dollars on green pork.”

Examining Supply-Side Options to Achieve 100% Clean Electricity by 2035 was written by research staff at the National Renewable Energy Laboratory, so its reliance on solar and wind energy to decarbonize the grid by 2035 is not surprising. But that’s a big ask for any variable energy technology, especially if the nation’s largest source of clean power—nuclear energy—is relegated to a supporting role. Massive additions of solar and wind energy on the order of 2 TW would require a supporting infrastructure of new transmission lines, as well as batteries and hydrogen for daily and seasonal energy storage that would drive demand and capacity requirements higher.

Advanced reactor developers are designing many new nuclear energy products, targeting commercial demonstration before 2030. These products aim to provide different products and grid services beyond what is provided by the first generations of commercial nuclear plants, namely, gigawatt-scale electricity production. These reactors are intended for deployment in many novel scenarios, including being closer to population centers. They will be sited in governmental processes that encourage far more public participation than was possible when many of the existing plants were sited and built in the 1960s and 1970s. This means that community engagement and approval likely will be critical for project success. This article, which discusses this issue of social license, is an adaptation of “Social license in the deployment of advanced nuclear technology,” published in Energies in 2021.¹ A more detailed discussion can be found in the original article.

Can nuclear power plants prosper in the grid of 2030 or 2035, when new wind and solar farms will make electricity prices even more volatile? Can plants install energy storage that will help them keep running at full power, 24/7, to ride out times of surplus and sell their energy only when prices are high?

In a May 15 piece, the editorial board of The Denver Gazette has weighed in on Colorado’s continuing controversy regarding how the state gets its electricity. While the current discourse in the state primarily pits fossil fuels against wind and solar, the board asks, “How about an energy source that generates almost limitless power, leaves no carbon footprint, and produces practically no emissions? It’s nuclear power—as green as you can get.”

Coal-fired plants fed the most power to Germany's electricity grid in the first half of 2021, while wind power dropped to its lowest level since 2018. As a September 13 article published on the German news site DW.com explained, the situation was blamed in part on a wind energy shortfall that is causing power price spikes across Europe.

Energy prices surged across Europe recently as markets were stricken by reduced output from wind turbines. Low supplies of natural gas had already boosted the cost of the gas–powered generation required to make up for dips in renewable energy sources. The result: a series of dire headlines, soaring prices for natural gas, and the startup of idled coal power plants.

America’s electric utility workers and nuclear engineers are ready to work together to help rapidly decarbonize and electrify the economy. We welcome provisions in the bipartisan infrastructure bill that aim to prevent premature closures of our nuclear power plants. Through measures such as production tax credits, President Biden can safeguard America’s largest carbon-free energy source by recognizing the clean-air contributions of nuclear energy.

Despite strong growth over the next two years, renewables such as hydropower, wind, and solar won’t keep up with the projected increase in global electricity demand in 2021 and 2022, according to the International Energy Agency’s Electricity Market Report—July 2021. The result could be a sharp rise in the use of coal power that risks pushing carbon dioxide emissions from the electricity sector to record levels next year.

The German animation studio Kurzgesagt released a new video to its English YouTube channel last week to answer the question, “Do we need nuclear energy to stop climate change?” The studio’s channel on YouTube is self-described as a small team working to make science look beautiful. Its videos discuss a variety of scientific, technological, philosophical, and psychological questions, and it has more than 14 million subscribers. The channel recently discussed the question of deaths caused by radiation—spoiler alert, nuclear is among the safest of all energy production.

A recent U.S. Energy Information Administration report, Short-Term Energy Outlook, notes that in 2020, nuclear power plants generated more electricity in the United States than coal-fired plants for the first time ever. Last year also marked the first time that coal generation was not the first or second largest U.S. electricity producer in more than 70 years.

Two factors led to the decrease in coal-fired generation, according to the EIA: one is the drop in the number of operating coal-fired plants, and the other is the lower utilization of those remaining coal-fired plants as the nation moves toward cleaner energy production. Coal, however, is not to be abandoned yet, according to the EIA.

The next couple of years will see changes in energy production, according to the EIA report. The EIA believes that "increases in natural gas prices will make coal more competitive in the electric power sector. This expected increase in coal's utilization more than offsets the upcoming retirement of 2.8 GW of coal capacity in 2021 and another 8.5 GW in 2022," based on information reported to the EIA by coal-fired plant owners and developers.

The Economist published a video earlier this month trying to answer the question of why is nuclear so unpopular. The video is paired with a story that appeared on The Economist's website advocating for a well-regulated nuclear industry. The video starts off with very dramatic images of nuclear weapons and scenes from popular culture like Godzilla, The Simpsons, and the recent HBO miniseries Chernobyl. The video provides a quick history of nuclear science and technology starting with Eisenhower's Atoms for Peace speech in an attempt to prove to the viewer that "nuclear is one of the safest, most reliable, and sustainable forms of energy, and decarbonizing will be much more difficult without it."

Granholm

U.S. Energy Secretary Jennifer Granholm gave her first international address as part of the Berlin Energy Transition Dialogue 2021 conference, held on March 16 and 17. Granholm started her speech by stating that “America is back,” putting climate change policies front and center as part of the Biden administration’s agenda. She said that President Biden has set ambitious goals for climate policies that will set the United States on “an irreversible path toward net zero carbon emissions by 2050.”

Granholm’s message: Granholm focused her talk on renewable energy investment and she discussed how the United States is dedicated to working with the rest of the world to cut emissions to get to net-zero. She touched on assorted topics, including investing in renewables, creating a resilient grid, installing hundreds of miles of new transmission lines to reach new renewable energy sources, improving carbon removal from current fossil fuels, promoting hydrogen production, researching next-generation battery storage, and realizing the potential massive economic boom that could come with all this investment by the U.S. Department of Energy.

There was one glaring omission from that list: Nuclear.
