The recent announcement by TVA of plans to build a natural gas-fired electric plant in Rogersville, may lead to the development of TennesseeÂ’s substantial natural gas potential, according to one industry source.

“TVA will need up to 160 million cubic feet of natural gas a day for the plant scheduled to come on line in late 2011. Tennessee is now producing about 16 million cubic feet of gas, but has immense potential to produce a great deal more gas,” said Scott Gilbert, President, Tennessee Oil& Gas Association (TOGA).

Gilbert, lead geologist for Vinland Energy, Oak Ridge, said that at least half of the counties in Tennessee have oil and gas potential.

“At this time, we are producing oil and gas from just 11 eastern and middle Tennessee counties, but there is reason to believe that most other eastern and middle Tennessee counties have potential for the production of gas or oil,” he added.

Gilbert noted that while there are several shallow and deep horizons capable of producing oil and gas in Tennessee, the most potential lies in a shale formation, called the Chattanooga Shale.

“The Chattanooga Shale lies like a blanket under the entire Cumberland Plateau and Highland Rim of eastern and middle Tennessee and in scattered locations in the rest of East Tennessee, at a depth of less than 1,000 feet to more than 4,000 feet,” Gilbert said. He noted that the shale gets deeper as you travel east.

“This rock formation, called the Chattanooga Shale in Tennessee is similar to the Marcellus Shale of New York and Pennsylvania and the Huron Shale of Eastern Kentucky. All three are Devonian Shales and underlie almost the entire Appalachian Basin from New York to Alabama.

“Geologists agree that as a resource, the shale is huge, but the challenges are many. Shales are different from conventional source rocks and we are just now learning how to unlock the shale’s potential,” he said.

Gilbert noted that the “shale play” started with the Barnett Shale play in Texas nearly a decade ago. The Barnett field is proven to have 2.5 trillion cubic feet of natural gas and is estimated to contain as much as 30 trillion cubic feet.

“The economic success of the Barnett Shale, which began production in 1999, has spurred companies to search for other sources of shale gas including the Antrim Shale in Michigan, the Fayetteville Shale in Arkansas, the Haynesville shale in Louisiana as well as the Marcellus Shale in Pennsylvania and now the Chattanooga Shale in Tennessee.

“The Chattanooga Shale is not as deep as the Marcellus. Deeper wells have higher pressure, which generally result in more production but also higher costs,” Gilbert pointed out. “However, the Chattanooga shale is certainly worth exploring for and producing. Several Tennessee companies already have commercially successful Chattanooga Shale wells, both vertical and horizontal. Now with a very large potential market for our gas to TVA, we lack only the infrastructure, which will come with the additional leasing and drilling we anticipate,” Gilbert predicted.

The proposed natural gas plant is to be located beside the John Sevier coal fired power plant, which supplies electricity to upper east Tennessee. The purpose is to reduce the emissions from the existing plant. The large majority of the coal currently burned in the John Sevier Plant is imported from neighboring states.

“The new gas fired plant will allow the State of Tennessee to provide homegrown, clean burning natural gas, which will result in more jobs and increased taxes going into state coffers in the form of severance tax from the production of the natural gas,” Gilbert noted.

Geothermal Power Plant In Hawaii Nearing Dangerous Meltdown?

Geothermal Power Plant Risks include hydrogen sulfide leaks, toxic gases, lava flow hazards, well blowouts, and earthquake-induced releases at sites like PGV and the Geysers, threatening public health, grid reliability, and environmental safety.

 

Key Points

Geothermal Power Plant Risks include toxic gases, lava impacts, well failures, and induced quakes that threaten health.

✅ Hydrogen sulfide exposure can cause rapid pulmonary edema.

✅ Lava can breach wells, venting toxic gases into communities.

✅ Induced seismicity may disrupt grids near PGV and the Geysers.

 

If lava reaches Hawaii’s PGV geothermal power plant, it could release of deadly hydrogen sulfide gas. That’s the latest potential danger from the Kilauea volcanic eruption in Hawaii. Residents now fear that lava flow will trigger a meltdown at the Puna Geothermal Venture (PGV) power plant that would release even more toxic gases into the air.

Nobody knows what will happen if lava engulfs the PGV because magma has never engulfed a geothermal power plant, Reuters reported. A geothermal power plant uses steam and gas heated by lava deep in the earth to run turbines that make electricity.

The PGV power plant produces 25% of the power used on Hawaii’s “Big Island.” The plant is considered a source of clean energy because geothermal plants burn no fossil fuels and produce little pollution under normal circumstances, even as nuclear retirements like Three Mile Island reshape low-carbon options.

 

The Potential Danger from Geothermal Energy

The fear is that the lava would release chemicals used to make electricity at the plant. The PGV has been shut down and authorities moved an estimated 60,000 gallons of flammable liquids away from the facility. They also shut down wells that extract steam and gas used to run the turbines.

Another potential danger is that lava would open the wells and release clouds of toxic gases from them. The wells are typically sealed to prevent the gas from entering the atmosphere.

The most significant threat is hydrogen sulfide, a highly toxic and flammable gas that is colorless. Hydrogen sulfide normally has a rotten egg smell which people might not detect when the air is full of smoke. That means people can breathe hydrogen sulfide in without realizing they have been exposed.

The greatest danger from hydrogen sulfide is pulmonary edema; the accumulation of fluid in the lungs, which causes a person to stop breathing. People have died of pulmonary edema after just a few minutes of exposure to hydrogen sulfide gas. Many victims become unconscious before the gas kills them. Long-term dangers that survivors of pulmonary edema face include brain damage.

Hydrogen sulfide can also cause burns to the skin that are similar to frostbite. Persons exposed to hydrogen sulfide can also suffer from nausea, headaches, severe eye burns, and delirium. Children are more vulnerable to hydrogen sulfide because it is a heavy gas that stays close to the ground.

 

Geothermal Danger Extends Far Beyond Hawaii

The danger from geothermal energy extends far beyond Hawaii. The world’s largest collection of geothermal power plants is located at the Geysers in California’s Wine Country, and regulatory timelines such as the postponed closure of three Southern California plants can affect planning.

The Geysers field contains 350 steam production wells and 22 power plants in Sonoma, Lake, and Mendocino counties. Disturbingly, the Geysers are located just north of the heavily-populated San Francisco Bay Area and just west of Sacramento, where preemptive electricity shutdowns have been used during extreme fire weather. Problems at the Geysers might lead to significant blackouts because the field supplies around 20% of the green energy used in California.

Another danger from geothermal power is earthquakes because many geothermal power plants inject wastewater into hot rock deep below to produce steam to run turbines, a factor under review as SaskPower explores geothermal in new settings. A geothermal project in Switzerland created Earthquakes by injecting water into the Earth, Zero Hedge reported. A theoretical threat is that quakes caused by injection would cause the release of deadly gases at a geothermal power plant.

The dangers from geothermal power might be much greater than its advocates admit, potentially increasing reliance on natural-gas-based electricity during supply shortfalls.

France Demonstrates the Role of Nuclear Power Plants

France Nuclear Power Strategy illustrates a low-carbon, reliable baseload complementing renewables in the energy transition, enhancing grid reliability, energy security, and emissions reduction, offering actionable lessons for Germany on infrastructure, policy, and public acceptance.

 

Key Points

France's nuclear strategy is a low-carbon baseload model supporting renewables, grid reliability, and energy security.

✅ Stable low-carbon baseload complements intermittent renewables

✅ Enhances grid reliability and national energy security

✅ Requires long-term investment, safety, and waste management

 

In recent months, France has showcased the critical role that nuclear power plants can play in an energy transition, offering valuable lessons for Germany and other countries grappling with their own energy challenges. As Europe continues to navigate its path towards a sustainable and reliable energy system, France's experience with nuclear energy underscores its potential benefits and the complexities involved, including outage risks in France that operators must manage effectively.

France, a long-time proponent of nuclear energy, generates about 70% of its electricity from nuclear power, making it one of the most nuclear-dependent countries in the world. This high reliance on nuclear energy has allowed France to maintain a stable and low-carbon electricity supply, which is increasingly significant as nations aim to reduce greenhouse gas emissions, even as Europe's nuclear capacity declines in several markets, and combat climate change.

Recent events in France have highlighted several key aspects of nuclear power's role in energy transition:

  1. Reliability and Stability: During periods of high renewable energy generation or extreme weather events, nuclear power plants have proven to be a stable and reliable source of electricity. Unlike solar and wind power, which are intermittent and depend on weather conditions, nuclear plants provide a consistent and continuous supply of power. This stability is crucial for maintaining grid reliability and ensuring that energy demand is met even when renewable sources are not producing electricity.

  2. Low Carbon Footprint: France’s commitment to nuclear energy has significantly contributed to its low carbon emissions. By relying heavily on nuclear power, France has managed to reduce its greenhouse gas emissions substantially compared to many other countries. This achievement is particularly relevant as Europe strives to meet ambitious climate targets, with debates over a nuclear option in Germany highlighting climate trade-offs, and reduce overall carbon footprints. The low emissions associated with nuclear power make it an important tool for achieving climate goals and transitioning away from fossil fuels.

  3. Energy Security: Nuclear power has played a vital role in France's energy security. The country’s extensive network of nuclear power plants ensures a stable and secure supply of electricity, reducing its dependency on imported energy sources. This energy security is particularly important in the context of global energy market fluctuations and geopolitical uncertainties. France’s experience demonstrates how nuclear energy can contribute to a nation’s energy independence and resilience.

  4. Economic Benefits: The nuclear industry in France also provides significant economic benefits. It supports thousands of jobs in construction, operation, and maintenance of power plants, as well as in the supply chain for nuclear fuel and waste management. Additionally, the stable and relatively low cost of nuclear-generated electricity can contribute to lower energy prices for consumers and businesses, enhancing economic stability.

Germany, in contrast, has been moving away from nuclear energy, particularly following the Fukushima disaster in 2011. The country has committed to phasing out its nuclear reactors by 2022 and focusing on expanding renewable energy sources such as wind and solar power. While Germany's renewable energy transition has made significant strides, it has also faced challenges related to grid stability, as Germany's energy balancing act illustrates for policymakers, energy storage, and maintaining reliable power supplies during periods of low renewable generation.

France’s experience with nuclear energy offers several lessons for Germany and other nations considering their own energy strategies:

  • Balanced Energy Mix: A diverse energy mix that includes nuclear power alongside renewable sources can help ensure a stable and reliable electricity supply, as ongoing discussions about a nuclear resurgence in Germany emphasize for policymakers today. While renewable energy is essential for reducing carbon emissions, it can be intermittent and may require backup from other sources to maintain grid reliability. Nuclear power can complement renewable energy by providing a steady and consistent supply of electricity.

  • Investment in Infrastructure: To maximize the benefits of nuclear energy, investment in infrastructure is crucial. This includes not only the construction and maintenance of power plants but also the development of waste management systems and safety protocols. France’s experience demonstrates the importance of long-term planning and investment to ensure the safe and effective use of nuclear technology.

  • Public Perception and Policy: Public perception of nuclear energy can significantly impact its adoption and deployment, and ongoing Franco-German nuclear disputes show how politics shape outcomes across borders. Transparent communication, rigorous safety standards, and effective waste management are essential for addressing public concerns and building trust in nuclear technology. France’s successful use of nuclear power is partly due to its emphasis on safety and regulatory compliance.

In conclusion, France's experience with nuclear power provides valuable insights into the role that this technology can play in an energy transition. By offering a stable, low-carbon, and reliable source of electricity, nuclear power complements renewable energy sources and supports overall energy security. As Germany and other countries navigate their energy transitions, France's example underscores the importance of a balanced energy mix, robust infrastructure, and effective public engagement in harnessing the benefits of nuclear power while addressing associated challenges, with industry voices such as Eon boss on nuclear debate underscoring the sensitivity of cross-border critiques.

Is a Resurgence of Nuclear Energy Possible in Germany?

Germany Nuclear Phase-Out reflects a decisive energy policy shift, retiring reactors as firms shun new builds amid high costs, radioactive waste challenges, climate goals, insurance gaps, and debate over small modular reactors and subsidies.

 

Key Points

Germany's policy to end nuclear plants and block new builds, emphasizing safety, waste, climate goals, and viability.

✅ Driven by safety risks, waste storage limits, and insurance gaps

✅ High capital costs and subsidies make new reactors uneconomic

✅ Political debate persists; SMRs raise cost and proliferation concerns

 

A year has passed since Germany deactivated its last three nuclear power plants, marking a significant shift in its energy policy.

Nuclear fission once heralded as the future of energy in Germany during the 1960s, was initially embraced with minimal concern for the potential risks of nuclear accidents. As Heinz Smital from Greenpeace recalls, the early optimism was partly driven by national interest in nuclear weapon technology rather than energy companies' initiatives.

Jochen Flasbarth, State Secretary in the Ministry of Development, reflects on that era, noting Germany's strong, almost naive, belief in technology. Germany, particularly the Ruhr region, grappled with smog-filled skies at that time due to heavy industrialization and coal-fired power plants. Nuclear energy presented a "clean" alternative at the time.

This sentiment was also prevalent in East Germany, where the first commercial nuclear power plant came online in 1961. In total, 37 nuclear reactors were activated across Germany, reflecting a widespread confidence in nuclear technology.

However, the 1970s saw a shift in attitudes. Environmental activists protested the construction of new power plants, symbolizing a generational rift. The 1979 Three Mile Island incident in the US, followed by the catastrophic Chornobyl disaster in 1986, further eroded public trust in nuclear energy.

The Chornobyl accident, in particular, significantly dampened Germany's nuclear ambitions, according to Smital. Post-Chernobyl, plans for additional nuclear power plants in Germany, once numbering 60, drastically declined.

The emergence of the Green Party in 1980, rooted in anti-nuclear sentiment, and its subsequent rise to political prominence further influenced Germany's energy policy. The Greens, joining forces with the Social Democrats in 1998, initiated a move away from nuclear energy, facing opposition from the Christian Democrats (CDU) and Christian Social Union (CSU).

However, the Fukushima disaster in 2011 prompted a policy reversal from CDU and CSU under Chancellor Angela Merkel, leading to Germany's eventual nuclear phase-out in March 2023, after briefly extending nuclear power amid the energy crisis.

Recently, the CDU and CSU have revised their stance once more, signaling a potential U-turn on the nuclear phaseout, advocating for new nuclear reactors and the reactivation of the last shut-down plants, citing climate protection and rising fossil fuel costs. CDU leader Friedrich Merz has lamented the shutdown as a "black day for Germany." However, these suggestions have garnered little enthusiasm from German energy companies.

Steffi Lemke, the Federal Environment Minister, isn't surprised by the companies' reluctance, noting their longstanding opposition to nuclear power, which she argues would do little to solve the gas issue in Germany, due to its high-risk nature and the long-term challenge of radioactive waste management.

Globally, 412 reactors are operational across 32 countries, even as Europe is losing nuclear power during an energy crunch, with the total number remaining relatively stable over the years. While countries like China, France, and the UK plan new constructions, there's a growing interest in small, modern reactors, which Smital of Greenpeace views with skepticism, noting their potential military applications.

In Germany, the unresolved issue of nuclear waste storage looms large. With temporary storage facilities near power plants proving inadequate for long-term needs, the search for permanent sites faces resistance from local communities and poses financial and logistical challenges.

Environment Minister Lemke underscores the economic impracticality of nuclear energy in Germany, citing prohibitive costs and the necessity of substantial subsidies and insurance exemptions.

As things stand, the resurgence of nuclear power in Germany appears unlikely, with economic factors playing a decisive role in its future.

Trump's Canada Tariff May Spike NY Energy Prices

25% Tariff on Canadian Imports threatens New York energy markets, disrupting hydroelectric power and natural gas supply chains, raising electricity prices, increasing gas costs, and intensifying trade tensions, policy uncertainty, and cross-border logistics risks.

 

Key Points

A U.S. policy imposing 25% duties on Canadian goods, risking higher New York electricity and natural gas costs.

✅ Hydroelectric and gas imports face costlier cross-border flows

✅ Higher utility bills for NY households and businesses

✅ Supply chain volatility and policy uncertainty increase

 

President Donald Trump announced the imposition of a 25% tariff on all imports from Canada, citing concerns over drug trafficking and illegal immigration. This decision has raised significant concerns among experts and residents in New York, who warn that the tariff could lead to increased electricity and gas prices in the state.

Impact on New York's Energy Sector

New York relies heavily on energy imports from Canada, particularly electricity and natural gas. Canada is a major supplier of hydroelectric power to the northeastern United States, including New York, with its electricity exports at risk amid trade tensions. The imposition of a 25% tariff on Canadian goods could disrupt this supply chain, leading to higher energy costs for consumers and businesses in New York. Justin Wilcox, an energy analyst, stated, "If the tariff is implemented, it could lead to increased costs for electricity and gas, affecting both consumers and businesses."

Potential Economic Consequences

The increased energy costs could have broader economic implications for New York, and some experts advise against cutting Quebec's exports to avoid exacerbating market volatility. Higher electricity and gas prices may lead to increased operational costs for businesses, potentially resulting in higher prices for goods and services, while tariff threats have boosted support for Canadian energy projects that could reshape regional supply. This could exacerbate the cost-of-living challenges faced by residents and strain the state's economy.

Political and Diplomatic Reactions

The tariff has also sparked political and diplomatic reactions, including threats to cut U.S. electricity exports from Ontario that raised tensions. New York Governor Kathy Hochul expressed concern over the potential economic impact, stating, "We are closely monitoring the situation and are prepared to take necessary actions to protect New York's economy." Additionally, Canadian officials have expressed their disapproval of the tariff, and Ontario Premier Doug Ford's Washington meeting underscored ongoing discussions, emphasizing the importance of the trade relationship between the two countries.

Historical Context

This development is part of a broader pattern of trade tensions between the United States and its neighbors. In 2018, the U.S. imposed tariffs on Canadian steel and aluminum, leading to retaliatory measures from Canada. The current situation underscores the ongoing challenges in international trade relations, where a recent tariff threat delayed Quebec's green energy bill and highlighted the potential domestic impacts of such policies.

The imposition of a 25% tariff on Canadian imports by President Trump has raised significant concerns in New York regarding potential increases in electricity and gas prices. Experts warn that this could lead to higher costs for consumers and businesses, with broader economic implications for the state. As the situation develops, it will be crucial to monitor the responses from both state and federal officials, as well as how Canadians support tariffs on energy and minerals may influence policy, and the potential for diplomatic negotiations to address these trade tensions.

3-layer non-medical masks now recommended by Canada's top public health doctor

Canada Three-Layer Mask Recommendation advises non-medical masks with a polypropylene filter layer and tightly woven cotton, aligned with WHO guidance, to curb COVID-19 aerosols indoors through better fit, coverage, and public health compliance.

 

Key Points

PHAC advises three-layer non-medical masks with a polypropylene filter to improve indoor COVID-19 protection.

✅ Two fabric layers plus a non-woven polypropylene filter

✅ Ensure snug fit: cover nose, mouth, chin without gaps

✅ Aligns with WHO guidance for aerosols and droplets

 

The Public Health Agency of Canada is now recommending Canadians choose three-layer non-medical masks with a filter layer to prevent the spread of COVID-19, even as an IEA report projects higher electricity needs for net-zero, as they prepare to spend more time indoors over the winter.

Chief Public Health Officer Dr. Theresa Tam made the recommendation during her bi-weekly pandemic briefing in Ottawa Tuesday, as officials also track electricity grid security amid critical infrastructure concerns.

"To improve the level of protection that can be provided by non-medical masks or face coverings, we are recommending that you consider a three-layer nonmedical mask," she said.

According to recently updated guidelines, two layers of the mask should be made of a tightly woven fabric, such as cotton or linen, and the middle layer should be a filter-type fabric, such as non-woven polypropylene fabric, as Canada explores post-COVID manufacturing capacity for PPE.

"We're not necessarily saying just throw out everything that you have," Tam told reporters, suggesting adding a filter can help with protection.

The Public Health website now includes instructions for making three-layer masks, while national goals like Canada's 2050 net-zero target continue to shape recovery efforts.

The World Health Organization has recommended three layers for non-medical masks since June, and experts note that cleaning up Canada's electricity is critical to broader climate resilience. When pressed about the sudden change for Canada, Tam said the research has evolved.

"This is an additional recommendation just to add another layer of protection. The science of masks has really accelerated during this particular pandemic. So we're just learning again as we go," she said.

"I do think that because it's winter, because we're all going inside, we're learning more about droplets and aerosols, and how indoor comfort systems from heating to air conditioning costs can influence behaviors."

She also urged Canadians to wear well-fitted masks that cover the nose, mouth and chin without gaping, as the federal government advances emissions and EV sales regulations alongside public health guidance.
