The debate over new carbon dioxide limits for power plants has centered on carbon capture technology, with the US Environmental Protection Agency (EPA) defending its readiness despite industry skepticism.
The EPA had finalized a rule establishing carbon emissions standards for coal- and new gas-fired generation, effectively requiring carbon capture technology for many power plants. This climate policy was first revealed in April last year.
Under the new EPA mandate, coal plants must implement carbon capture and storage (CCS) technology. This technology involves capturing CO2 from power plant emissions and then storing it underground to prevent it from entering the atmosphere.
The EPA’s New Mandate for Coal Plants
The directive is a bold ultimatum for coal-fired power plants to either capture their smoketstack emissions or face shut down. The new rule aligns with President Joe Biden’s pledge to combat carbon pollution from fossil fuel-fired electric plants by 2035 and economy-wide by 2050.
The latest restrictions on GHG emissions represent the Biden administration’s most aggressive stance to fight global warming. President Biden’s National Climate Advisor Ali Zaidi, made a promise that,
“This year, the United States is projected to build more new electric generation capacity than we have in two decades – and 96 percent of that will be clean,”

Here are the main points of the EPA’s new carbon emissions rule for power plants:
- Existing coal-fired plants intending long-term operation and all new baseload gas-fired plants must control 90% of their carbon pollution.
- Boost the Mercury and Air Toxics Standards (MATS) for coal-fired power plants, tightening toxic metal emissions standards by 67% and finalizing a 70% reduction in mercury emissions from existing lignite-fired sources
- Cut pollutants discharged through wastewater from coal-fired power plants by over 660 M pounds/year, guaranteeing cleaner water for impacted communities, particularly those with environmental justice concerns facing disproportionate impacts.
- Safe management of coal ash in previously unregulated areas, including disposal sites prone to leakage and groundwater contamination.
Coal remains the largest energy source for electricity generation, steelmaking, and cement production. However, it’s also the largest source of man-made carbon dioxide (CO2) emissions.
The Rule’s Climate Impact and Benefits
The EPA’s finalized rule on carbon emissions standards for power plants is projected to have significant financial and climate impacts.
According to EPA estimates, industry compliance with the rule could cost between $7.5 billion and $19 billion through 2047. However, the agency also anticipates substantial climate and public health benefits, totaling to $370 billion over the next two decades.
- In terms of emissions reductions, the rule is forecasted to prevent 38 million metric tons of CO2 emissions in 2028 and 123 million metric tons in 2035.
Mona Dajani, global co-chair of energy, infrastructure, and hydrogen at Baker Botts, emphasized that the rule sends a clear message to power plant operators about the end of unlimited carbon pollution. While carbon capture technology will contribute to emissions reductions, the EPA projects that the greatest impact will come from coal plant retirements prompted by the rule.
By 2035, the agency expects US coal-fired capacity to decrease to about 20 GW, comprising 19 GW with carbon capture and 1 GW with natural gas co-firing. This contrasts with a scenario without the regulations, where coal-fired capacity would consist of 11 GW with carbon capture and 41 GW of unabated coal plants.

Regarding gas-fired generation, the EPA anticipates 1GW of capacity with carbon capture and 484 GW without carbon capture by 2035. Additionally, the EPA announced plans to set carbon limits for existing gas-fired power plants in a future rulemaking process.
However, this decision has ignited debate from industrialists and environmental stalwarts. Trade groups also criticized the standards, questioning the feasibility of capturing and storing CO2 emissions, echoing concerns raised after the EPA’s initial proposal in May 2023.
Challenges and Controversies
Dan Brouillette, president and CEO of the Edison Electric Institute (EEI), stated that CCS is not yet ready for full-scale deployment and that there isn’t enough time to develop the necessary infrastructure for compliance by 2032.
While CCS involves scrubbing CO2 from emissions sources like power plants for underground storage, operational implementations are not enough. Currently, only one utility-scale US power plant, W.A. Parish 5-8, utilizes carbon capture technology, with the captured gas used for oil extraction. The abandonment of another project in Kemper County, Miss., led to significant costs for Southern Co., raising doubts about CCS.
Some industry groups, such as the National Rural Electric Cooperative Association (NRECA), have challenged the legality of the rule. NRECA CEO Jim Matheson criticized the rule as unlawful, unrealistic, and unachievable, arguing that it undermines electric reliability and poses risks to an already strained electric grid.
-
However, the EPA highlighted technological advancements and federal incentives making CCS more economically viable in its final rule.
The expansion of tax credits for carbon capture under the US Inflation Reduction Act in 2022, now valued at up to $85 per metric ton of CO2 stored, has bolstered support. Additionally, process improvements from previous CCS deployments have contributed to cost reductions.
The EPA noted that some companies have already planned to install CCS on their units independent of regulatory requirements, indicating growing industry interest in the technology’s potential.
The new rule’s first provision allows units to respond to declared grid emergencies without being held accountable for their CO2 emissions, providing a short-term mechanism to address urgent situations. The second provision permits US states to delay compliance measures for certain units in the event of unanticipated grid reliability issues.
States have the option to include both reliability exceptions in the plans they submit to the EPA for implementing the new rule.
As the debate rages on, the EPA’s carbon emission standards mark a pivotal moment in the nation’s energy transition, highlighting the delicate balance between environmental goals and industry realities.

Carbon Footprint
Why a forest with more species stores more carbon
A forest is not just trees. The number of species it holds, from canopy giants to understorey shrubs to soil fungi, directly determines how much carbon it can absorb, and, more importantly, how much it can keep over time. Buyers of carbon credits increasingly ask a reasonable question: Is the carbon in this project long-lasting? The science of biodiversity has a clear answer.

OpenAI Hits Pause on $40B UK AI Project: Energy Costs Shake Data Center Economics
ChatGPT developer OpenAI has paused its flagship UK data center project, known as “Stargate UK,” citing high energy costs and regulatory uncertainty. The project was part of a broader £31 billion ($40+ billion) investment plan aimed at expanding artificial intelligence (AI) infrastructure in the country.
The initiative was designed to deploy up to 8,000 GPUs initially, with plans to scale to 31,000 GPUs over time. It was aimed to boost the UK’s “sovereign compute” capacity. This means building local infrastructure to support AI development and reduce reliance on foreign systems.
However, the company has now paused development. An OpenAI spokesperson stated that they:
“…support the government’s ambition to be an AI leader. AI compute is foundational to that goal – we continue to explore Stargate UK and will move forward when the right conditions such as regulation and the cost of energy enable long-term infrastructure investment.”
Energy Costs Are Now a Core Constraint
The main issue is energy. AI data centers require large amounts of electricity to run GPUs and cooling systems.
In the UK, industrial electricity prices are among the highest in developed markets. Recent estimates show costs at around £168 per megawatt-hour, compared to £69 in France and £38 in Texas. This gap creates a major disadvantage for large-scale data center investments.
AI workloads are especially power-intensive. A single large data center can consume as much electricity as tens of thousands of homes. As AI adoption grows, this demand is rising quickly.
Globally, the International Energy Agency estimates that data centers could consume over 1,000 terawatt-hours (TWh) of electricity by 2030, up sharply from about 415 TWh in 2024. This growth is largely driven by AI.

The result is clear. Energy is no longer just a cost. It is a key factor in where AI infrastructure gets built.
Regulation Adds Another Layer of Risk
Energy is only part of the challenge. Regulation is also slowing investment. In the UK, uncertainty around AI rules, especially copyright laws for training data, has created hesitation among companies.
Earlier proposals to allow AI firms to use copyrighted content were withdrawn after backlash. This left companies without clear guidance on compliance.
For large infrastructure projects, this uncertainty increases risk. Data centers require billions in upfront investment. Companies need stable rules before committing capital.
Planning delays and grid connection timelines also add friction. These factors increase both cost and project timelines.
Together, energy costs and regulatory uncertainty create a difficult environment for hyperscale AI infrastructure.
OpenAI’s Global Infrastructure Expands, But More Selectively
Despite the pause, ChatGPT-maker is still expanding globally. The company is investing heavily in AI infrastructure through partnerships with Microsoft, NVIDIA, and Oracle. It is also linked to a much larger $500 billion “Stargate” initiative in the United States, focused on building next-generation AI data centers.
At the same time, the company faces rising costs. Reports suggest OpenAI could lose billions of dollars annually as it scales infrastructure to meet demand.
This reflects a broader industry shift. AI is becoming more like energy or telecom infrastructure. It requires large capital investment, long timelines, and stable operating conditions.
The pause also highlights a deeper issue. AI growth is increasing pressure on energy systems and the environment.
The Hidden Carbon Cost Behind Every AI Query
ChatGPT and similar tools rely on large data centers. These facilities already account for about 1% to 1.5% of global electricity use. Projections for their energy use vary widely due to various factors.
Each individual query may seem small. A typical ChatGPT request can use about 0.3 watt-hours of electricity, which is relatively low. However, usage at scale changes the picture.
ChatGPT now serves hundreds of millions of users. Even small energy use per query adds up quickly. Training models is even more energy-intensive. For example, training GPT-3 required about 1,287 megawatt-hours of electricity and produced roughly 550 metric tons of CO₂.

Newer models are even larger. Some estimates suggest training advanced models like GPT-4 could emit up to 15,000 metric tons of CO₂, depending on the energy source.
At the system level, the impact is growing fast. AI systems could generate between 32.6 and 79.7 million tons of CO₂ emissions in 2025 alone. By 2030, AI-driven data centers could add 24 to 44 million tons of CO₂ annually.

Looking further ahead, global generative AI emissions could reach up to 245 million tons per year by 2035 if growth continues. These numbers show a clear pattern. Efficiency is improving, but total demand is rising faster.
Big Tech Scrambles to Balance AI Growth and Emissions
OpenAI has not published a detailed standalone net-zero target. However, its operations rely heavily on partners such as Microsoft, which has committed to becoming carbon negative by 2030.
The company has acknowledged that energy use is a real concern. Leadership has pointed to the need for more renewable energy, including nuclear and clean power, to support AI growth.
Across the industry, companies are responding in several ways:
- Improving model efficiency to reduce energy per query
- Investing in renewable energy and long-term power contracts
- Exploring new cooling systems to reduce water and energy use
Efficiency gains are already visible. Some AI systems have reduced energy per query by more than 30 times within a year, showing how quickly technology can improve. Still, total emissions continue to rise because demand is scaling faster than efficiency gains.
The Global AI Infrastructure Race
The pause in the UK highlights a larger trend. AI infrastructure is becoming a global competition shaped by energy, policy, and cost.
Regions with lower energy prices and faster permitting processes have an advantage. The United States and parts of the Middle East are attracting large-scale AI investments due to cheaper power and supportive policies.
At the same time, governments are trying to attract these projects. The UK has pledged billions to support AI growth and improve compute capacity. But this case shows that policy ambition alone is not enough. Companies need reliable energy, clear rules, and predictable costs.
AI’s Next Phase Will Be Decided by Energy, Not Code
The decision by OpenAI does not signal a retreat from AI investment. Instead, it reflects a shift in priorities.
Companies are becoming more selective about where they build infrastructure. They are focusing on locations that offer the right mix of energy access, cost stability, and regulatory clarity.
The UK project may still move forward, but only if conditions improve. For now, the message is clear. The future of AI will not be shaped by technology alone. It will also depend on energy systems, policy frameworks, and long-term investment conditions.

U.S. Uranium Mining Returns: UEC Launches First New Mine in a Decade
Uranium Energy Corporation (NYSE: UEC) has started production at its Burke Hollow project in South Texas. This is the first new uranium mine to open in the U.S. in over ten years.
The project started production in April 2026 after getting final regulatory approval. This marks a big step for domestic uranium supply. It’s also the world’s newest in-situ recovery (ISR) uranium mine, which shows a move toward less harmful extraction methods.
Burke Hollow was originally discovered in 2012 and spans roughly 20,000 acres, with only about half of the site explored so far. This suggests significant long-term expansion potential as additional wellfields are developed.
The mine’s output will go to UEC’s Hobson Central Processing Plant in Texas. This plant can produce up to 4 million pounds of uranium each year.
A Scalable ISR Platform Expands U.S. Uranium Capacity
The Burke Hollow launch transforms UEC into a multi-site uranium producer in the United States. The company runs two active ISR production platforms. The second one is at its Christensen Ranch facility in Wyoming; both are shown in the table from UEC.


This “hub-and-spoke” model allows uranium from multiple wellfields to be processed through centralized facilities, improving efficiency and scalability. UEC’s operations in Texas and Wyoming are now active. This gives them a licensed production capacity of about 12 million pounds per year across the U.S.
ISR mining plays a key role in this strategy. Unlike conventional mining, ISR involves circulating solutions underground to dissolve uranium and pump it to the surface. This reduces surface disturbance and can lower environmental impact compared to open-pit or underground mining.
Burke Hollow is the largest ISR uranium discovery in the U.S. in the last ten years. This boosts its long-term value as a domestic resource.
Unhedged Strategy Pays Off as Uranium Prices Rise
UEC’s production launch comes at a time of strong uranium market conditions. The company uses a fully unhedged strategy. This means it sells uranium at current market prices instead of securing long-term contracts.
This approach has recently delivered strong financial results. In early 2026, UEC sold 200,000 pounds of uranium for $101 each. This price was about 25% higher than average market rates. The sale brought in over $20 million in revenue and around $10 million in gross profit.
The strategy allows the company to benefit directly from rising uranium prices, which have been supported by:
- Growing global nuclear energy demand
- Supply constraints in key producing regions
- Increased long-term contracting by utilities
Unhedged exposure raises risk in downturns, but offers more upside in strong markets. UEC is currently taking advantage of this.
Nuclear Energy Growth Is Driving Demand for Uranium
The timing of Burke Hollow’s launch aligns with a broader global shift back toward nuclear energy. Governments are increasingly turning to nuclear power as a reliable, low-carbon energy source.

The International Atomic Energy Agency projects that global nuclear capacity could double by 2050, depending on policy and investment trends. This would require a significant increase in uranium supply.
In the United States, nuclear energy accounts for around 20% of electricity generation. It also produces zero carbon emissions during operations. This makes it a key component of many net-zero strategies.
There are several factors supporting renewed nuclear demand, including:
- Development of small modular reactors (SMRs)
- Extension of existing nuclear plant lifetimes
- Government funding to maintain nuclear capacity
- Rising electricity demand from data centers and electrification
As demand grows, securing a reliable uranium supply becomes increasingly important.

Reducing Import Risk: A Strategic Domestic Supply Push
The Burke Hollow project also addresses a major vulnerability in U.S. energy policy. The country currently imports about 95% of its uranium needs, leaving it exposed to global supply risks.
A large share of uranium production and enrichment capacity is concentrated in a few countries, including Russia and Kazakhstan. This concentration has raised concerns about supply disruptions and geopolitical risk.

By expanding domestic production, UEC is helping to reduce reliance on imports and strengthen the U.S. nuclear fuel supply chain.
The company’s broader strategy includes building a vertically integrated platform covering mining, processing, and, eventually, uranium conversion. This approach aligns with U.S. government efforts to rebuild domestic nuclear fuel capabilities.
Federal programs have allocated billions to boost uranium production and enrichment. This shows how important the sector is.
Two Hubs, One Strategy: Wyoming Supports the Texas Breakthrough
While Burke Hollow is the main focus, UEC’s Christensen Ranch operation in Wyoming remains an important part of its production base.
The Wyoming site has recently received approvals for expanded wellfield development, allowing it to increase output alongside the Texas operation.
Together, the two sites form the foundation of UEC’s dual-hub production model. However, it is the Texas project that marks the first new U.S. uranium mine in over a decade, making it the central milestone in the company’s growth strategy.
Investor Momentum Builds Around Uranium Revival
The restart of U.S. uranium production is drawing strong attention from investors and industry players. Uranium markets have tightened in recent years, driven by rising demand and limited new supply.
UEC’s production launch has already had a positive market impact. The company’s share price rose following the announcement, reflecting investor confidence in its growth strategy.

At the same time, utilities are increasing long-term contracting activity to secure fuel supply. This trend is expected to continue as new nuclear capacity comes online and existing plants extend operations.
Industry forecasts suggest that uranium demand will remain strong through the 2030s, supporting higher prices and increased investment in new production.
Lower Impact Mining, Higher ESG Expectations
The use of ISR mining at Burke Hollow reflects a broader shift toward more sustainable extraction methods. ISR typically reduces land disturbance and avoids large-scale excavation.
However, environmental management remains critical. Key issues include groundwater protection, chemical use, and long-term site restoration.
UEC has emphasized environmental controls and regulatory compliance in its operations. These efforts are important for maintaining social license and meeting ESG expectations.
From a climate perspective, uranium production plays an indirect but important role. Supporting nuclear energy, it helps enable low-carbon electricity generation and reduces reliance on fossil fuels.
The Bottom Line: A Defining Moment for U.S. Uranium Production
The launch of the Burke Hollow mine marks a major milestone for the U.S. uranium sector. It ends a decade-long gap in new mine development and signals renewed momentum in domestic production.
In the short term, it strengthens supply and supports rising uranium markets. In the long term, it highlights the growing role of nuclear energy in global decarbonization strategies.
UEC’s Burke Hollow shows that new uranium projects can advance in today’s market. There are still challenges, like scaling production and handling environmental risks, but progress is possible.
As demand for nuclear energy continues to grow, domestic projects like Burke Hollow will play a key role in shaping the future of energy security and low-carbon power.
