In Texas, home to some of the world's biggest oil companies, you might think the case for renewable energy would be tough to make. As it happened it was tough, but not impossible.

It was simply a case of showing that technologies like massive wind turbines and solar roof shingles would do the job with costs that were in line with power generated from fossil fuel, said Jim Marston, of the Texas office of Environmental Defense, an advocacy group.

Texas is one of more than 20 states which, lacking a lead from central government in Washington and spurred by mounting evidence of the threat of global warming, have pressed ahead with their own measures to boost renewable energy use and curb emissions of carbon dioxide, held largely responsible for pushing up world temperatures.

President George W. Bush, having rejected the ground-breaking Kyoto Protocol on curbing carbon dioxide on the ground that the U.S. economy could not afford it, in January acknowledged the challenge of climate change in his State of the Union address and spoke of new technologies and alternative fuels as possible solutions.

Initiatives taken in the United States, the world's largest greenhouse gas polluter accounting for nearly one quarter of all carbon emissions, are watched closely by scientists and governments round the world, hoping Bush's recognition of the need to curb emissions will be followed by meaningful action.

Just days after Bush's address, the Intergovernmental Panel on Climate Change released a report in Paris saying that global warming was "unequivocal" and that human use of fossil fuels almost certainly caused the rise in world temperatures recorded over the last half-century.

The panel forecast further temperature rises in the coming decades that would bring more severe storms, worse droughts and rising seas, threatening coastal areas and possibly forcing millions of people from low-lying land.

The Democratic victory in mid-term congressional elections last year has led to predictions by environmental groups, and some legislators, that the U.S. will set mandatory limits on carbon emissions by the end of this congressional session in 2008.

Some 20 states, refusing to wait for a change of course in Washington, have already taken a variety of steps to tackle climate change, including setting requirements for renewable energy use ranging from 2.2 percent of total electricity generation in Wisconsin to 25 percent in Minnesota.

In Texas, Marston of Environmental Defense said direct action had proved convincing.

"We literally brought in a truck with the wind turbines... then we also showed some of the really interesting cutting-edge technology that's happening in solar, literally having solar panels built into roof shingles," he said in a telephone interview.

That helped convince Texas lawmakers to require that some part of the state's electric power needs be met with alternative energy, he said. To keep the pressure on after the law was passed in 1999, environmental advocates used an age-old spur: competition.

"What we do in Texas is, we talk about keeping up with your neighbors," Marston said. "We were really proud when we passed our law in 1999... within a few years a lot of other states had passed us by, so we caught up to become number one again."

That meant raising the amount of renewable energy required, or what bureaucrats call the 'renewable portfolio standard.'

On the other hand Texas, where Bush has a ranch, remains one of the country's biggest energy users and one company is trying to build 12 more coal-fired plants there, which would dent the state's green credentials.

California, a longtime leader in the drive for renewables, approved a law last September to require cuts in greenhouse gases, while eight eastern states joined in a regional plan to cut emissions of carbon dioxide.

California Gov. Arnold Schwarzenegger and Sen. John McCain of Arizona have called for California's new low-carbon fuel standard, meant to cut the carbon content of transportation fuels by 10 percent by 2020, to be rolled out nationwide.

"We have been working toward this commitment to renewable energy and to the environment for 30 years, and our first global climate change legislation went into effect in 1986," said Claudia Chandler of the California Energy Commission.

Does that mean the states are the place to press the case for alternative energy? Not entirely, according to Chuck Kutscher of the National Renewable Energy Laboratory.

"Climate change is such a big problem, I really do think we need to attack this on several different levels," Kutscher said in a telephone interview from Boulder, Colorado.

Kutscher noted that the use of renewable energy, including biofuels and geothermal power, was only part of the solution.

Data in a report he edited, "Tackling Climate Change in the U.S.", showed energy efficiency would offset more carbon emissions than all available renewable energies combined.

"We don't have to convince everybody," Kutscher said. "People who are passionate about this can influence policy. I think the new Congress is reacting to the segment of the population that is really demanding action."

Alberta Faces Challenges with Solar Energy Expansion

Alberta Solar Energy Expansion confronts high installation costs, grid integration and storage needs, and environmental impact, while incentives, infrastructure upgrades, and renewable targets aim to balance reliability, land use, and emissions reductions provincewide.

 

Key Points

Alberta Solar Energy Expansion is growth in solar tempered by costs, grid limits, environmental impact, and incentives.

✅ High capex and financing challenge utility-scale projects

✅ Grid integration needs storage, transmission, and flexibility

✅ Site selection must mitigate land and wildlife impacts

 

Alberta's push towards expanding solar power is encountering significant financial and environmental hurdles. The province's ambitious plans to boost solar power generation have been met with both enthusiasm and skepticism as stakeholders grapple with the complexities of integrating large-scale solar projects into the existing energy framework.

The Alberta government has been actively promoting solar energy as part of its strategy to diversify the energy mix in a province that is a powerhouse for both green energy and fossil fuels today and reduce greenhouse gas emissions. Recent developments have highlighted the potential of solar power to contribute to Alberta's clean energy goals. However, the path forward is fraught with challenges related to costs, environmental impact, and infrastructure needs.

One of the primary issues facing the solar energy sector in Alberta is the high cost of solar installations. Despite decreasing costs for solar technology in recent years, the upfront investment required for large-scale solar farms remains substantial, even as some facilities have been contracted at lower cost than natural gas in Alberta today. This financial barrier has led to concerns about the economic viability of solar projects and their ability to compete with other forms of energy, such as natural gas and oil, which have traditionally dominated Alberta's energy landscape.

Additionally, there are environmental concerns associated with the development of solar farms. While solar energy is considered a clean and renewable resource, the construction of large solar installations can have environmental implications. These include potential impacts on local wildlife habitats, land use changes, where approaches like agrivoltaics can co-locate farming and solar, and the ecological effects of large-scale land clearing. As solar projects expand, balancing the benefits of renewable energy with the need to protect natural ecosystems becomes increasingly important.

Another significant challenge is the integration of solar power into Alberta's existing energy grid. Solar energy production is variable and dependent on weather conditions, especially with Alberta's limited hydro capacity for flexibility, which can create difficulties in maintaining a stable and reliable energy supply. The need for infrastructure upgrades and energy storage solutions is crucial to address these challenges and ensure that solar power can be effectively utilized alongside other energy sources.

Despite these challenges, the Alberta government remains committed to advancing solar energy as a key component of its renewable energy strategy. Recent initiatives include financial incentives and support programs aimed at encouraging investment in solar projects and supporting a renewable energy surge that could power thousands of jobs across Alberta today. These measures are designed to help offset the high costs associated with solar installations and make the technology more accessible to businesses and homeowners alike.

Local communities and businesses are also playing a role in the growth of solar energy in Alberta. Many are exploring opportunities to invest in solar power as a means of reducing energy costs and supporting sustainability efforts and, increasingly, to sell renewable energy into the market as demand grows. These smaller-scale projects contribute to the overall expansion of solar energy and demonstrate the potential for widespread adoption across the province.

The Alberta government has also been working to address the environmental concerns associated with solar energy development. Efforts are underway to implement best practices for minimizing environmental impacts and ensuring that solar projects are developed in an environmentally responsible manner. This includes conducting environmental assessments and working with stakeholders to address potential issues before projects are approved and built.

In summary, while Alberta's solar energy initiatives hold promise for advancing the province's clean energy goals, they are also met with significant financial and environmental challenges. Addressing these issues will be crucial to the successful expansion of solar power in Alberta. The government's ongoing efforts to support solar projects through incentives and infrastructure improvements, coupled with responsible environmental practices, will play a key role in determining the future of solar energy in the province.

The Innovative Solution Bringing Electricity To Crisis Stricken Areas

Toyota and Honda Moving e delivers hydrogen backup power via a fuel cell bus, portable batteries, and power exporters for disaster relief, emergency electricity, and grid outage support near charging stations and microgrids.

 

Key Points

A hydrogen mobile power system using a fuel cell bus and batteries to supply emergency electricity during disasters.

✅ Fuel cell bus outputs up to 18 kW, 454 kWh capacity

✅ Portable batteries and power exporter deliver site power

✅ Supports disaster relief near hydrogen charging stations

 

Without the uninterrupted supply of power and electricity, modern economies would be unable to function. A blackout can impact everything from transport to health care, communication, and even water supplies, as seen in a near-blackout in Japan that strained the grid. It is one of the key security concerns for every government on earth, a point underscored by Fatih Birol on electricity options during the pandemic, and the growth in the market for backup power reflects that fact. In 2018, the global Backup Power market was $14.9 billion and is expected to reach $22 billion by the end of 2025, growing at a CAGR of 5.0 percent between 2019 and 2025.

It is against this backdrop that Toyota and Honda have come up with a new and innovative solution to providing electricity during disasters. The two transport giants have launched a mobile power generation system that consists of a fuel cell bus that can carry a large amount of hydrogen, aligned with Japan's hydrogen energy system efforts underway, portable external power output devices, and portable batteries to disaster zones. The system, which is called ‘Moving e’ includes Toyota’s charging station fuel cell bus, Honda’s power exporter 9000 portable external power output device, two types of Honda’s portable batteries, and a Honda Mobile Power Pack Charge & Supply Concept charger/discharger for MPP. 

In simple terms, the bus would drive to a disaster zone, and while other approaches such as gravity energy storage are advancing, the portable batteries and power output devices would be used to extract electricity from the fuel cell bus and provide it wherever it is needed. The bus itself can generate 454kWh and has a maximum output of 18kW. That is more than enough energy to supply electricity for large indoor areas such as an evacuation area. The bus is also fitted with space for people to nap or rest during a disaster.

The two companies plan to test the effectiveness of the Moving e at multiple municipalities and businesses. These locations will have to be within 100km of a hydrogen station that is capable of refueling the bus. If the bus has to drive 200km, then its electricity supply to the disaster zone would drop from 490kwh to 240kWh. While there aren’t currently enough hydrogen stations to make this a realistic scenario for all disaster zones, especially as countries push for hydrogen-ready power plants in Germany and related infrastructure, hydrogen is growing increasingly competitive with gasoline and diesel.

While gas generators are still considered more reliable and generally cheaper than backup batteries for home use, cleaner backup power is growing increasingly popular, and novel storage like power-to-gas in Europe is also advancing across grids. This latest development by Toyota and Honda is another step forward for the battery and fuel cell industry, with initiatives like PEM hydrogen R&D in China accelerating progress, – especially considering the meteoric rise of hydrogen energy in recent years.

Snohomish PUD Hikes Rates Due to Severe Weather Impact

Snohomish PUD rate increase addresses storm recovery after a bomb cyclone and extended cold snap, stabilizing finances and grid reliability while offering assistance programs, payment plans, and energy efficiency for customers.

 

Key Points

Temp 5.8% residential hike in Feb 2025 to recover storm costs, meet cold snap demand, and uphold reliable service.

✅ 5.8% residential increase effective Feb 2025

✅ Driven by bomb cyclone damage and cold snap demand

✅ Aid includes payment plans, efficiency rebates, low income support

 

In early February 2025, the Snohomish County Public Utility District (PUD) announced a temporary increase in electricity rates to offset the financial impact of severe weather events, including a bomb cyclone and an extended cold snap, that occurred in late 2024. This decision aims to stabilize the utility's finances, a pattern seen at other utilities such as Florida Power & Light, which pursued a hurricane surcharge to recover storm costs, while ensuring continued service reliability for its customers.

Background of the Weather Events

In November 2024, the Pacific Northwest experienced a powerful bomb cyclone—a rapidly intensifying storm characterized by a significant drop in atmospheric pressure. This event brought heavy rainfall, strong winds, and widespread power outages across the region. Compounding the situation, a prolonged cold weather period in December 2024 and January 2025 led to increased energy demand, and similar conditions drove up Pennsylvania power rates in the same winter season, as residents and businesses relied heavily on heating systems.

Impact on Snohomish PUD

The combination of the bomb cyclone and the subsequent cold weather placed considerable strain on the Snohomish PUD's infrastructure and financial resources. The utility incurred substantial costs for emergency repairs, restoration efforts, and the procurement of additional electricity to meet the heightened demand during the cold snap. These unforeseen expenses prompted the PUD to seek a temporary rate adjustment to maintain financial stability and continue providing reliable service to its customers.

Details of the Rate Increase

Effective February 2025, the Snohomish PUD implemented a temporary electricity rate increase of 5.8% for residential customers, compared with a 3% BC Hydro increase in the same region for context. This adjustment is designed to recover the additional costs incurred during the severe weather events. The PUD has communicated that this rate increase is temporary and will be reevaluated after a specified period to determine if further adjustments are necessary.

Customer Impact and Assistance Programs

While the rate increase is intended to be temporary, it may still pose a financial burden for some customers, even as some markets expect rates to stabilize in 2025 in other jurisdictions. To mitigate this impact, the Snohomish PUD has outlined several assistance programs:

  • Payment Plans: Customers facing financial hardship can enroll in extended payment plans to spread the cost of the increased rates over a longer period.

  • Energy Efficiency Programs: The PUD offers incentives and resources to help customers reduce energy consumption, potentially lowering their overall bills.

  • Low-Income Assistance: Eligible low-income customers may qualify for additional support through state and federal assistance programs.

The utility encourages customers to contact their customer service department to explore these options and find the best solutions for their individual circumstances.

Community Response and Future Considerations

The announcement of the rate increase has elicited mixed reactions from the community. Some residents express understanding, recognizing the necessity of maintaining infrastructure and service reliability. Others have voiced concerns about the financial impact, particularly among vulnerable populations, a debate also seen with higher BC Hydro rates in nearby British Columbia.

Looking ahead, the Snohomish PUD is committed to enhancing its infrastructure to better withstand future extreme weather events, an approach aligned with other utilities' multi-year rate proposals to fund upgrades. This includes investing in grid modernization, implementing advanced weather forecasting tools, and developing comprehensive emergency response plans. The utility also plans to engage with the community through public forums and surveys to gather feedback and collaboratively develop strategies that balance financial sustainability with customer affordability.

The temporary electricity rate increase by the Snohomish County Public Utility District reflects the financial challenges posed by severe weather events and parallels regional trends, including BC Hydro's 3.75% over two years adjustments, and underscores the importance of proactive infrastructure investment and community engagement. While the rate adjustment aims to stabilize the utility's finances, the PUD remains focused on supporting its customers through assistance programs and ongoing efforts to enhance service reliability and resilience against future climate-related events.

Energy groups warn Trump and Perry are rushing major change to electricity pricing

DOE Grid Resilience Pricing Rule faces FERC review as energy groups challenge an expedited timeline to reward coal and nuclear for reliability in wholesale markets, impacting natural gas, renewables, baseload economics, and grid pricing.

 

Key Points

A DOE proposal directing FERC to compensate coal and nuclear plants for reliability attributes in wholesale markets.

✅ Industry coalition seeks normal FERC timeline and review

✅ Impacts wholesale pricing, baseload economics, reliability

✅ Request for 90-day comments and reply period

 

A coalition of 11 industry groups is pushing back on Energy Secretary Rick Perry's efforts to quickly implement a major change to the way electric power is priced in the United States.

The Energy Department on Friday proposed a rule that stands to bolster coal and nuclear power plants by forcing the regional markets that set electricity prices to compensate them for the reliability they provide. Perry asked the Federal Energy Regulatory Commission to consider and finalize the rule within 60 days, including a 45-day period during which stakeholders can issue comments.

On Monday, groups representing petroleum, natural gas, electric power and renewable energy interests including ACORE urged FERC to reject the expedited process, as well as the Department of Energy's request that the regulatory commission consider putting in place an interim rule.

They say the time frame is "aggressive" and the department didn't provide adequate justification for fast-tracking a process that could have huge impacts on wholesale electricity markets.

"This is one of the most significant proposed rules in decades related to the energy industry and, if finalized, would unquestionably have significant ramifications for wholesale markets under the Commission's jurisdiction," the groups said in the motion filed with FERC.

"The Energy Industry Associations urge the Commission to reject the proposed unreasonable timelines and instead proceed in a manner that would afford meaningful consideration of public comments and be consistent with the normal deliberative process that it typically affords such major undertakings," they said.

The groups are requesting a 90-day comment period, as well as another period for reply comments. FERC, which has authority to regulate interstate transmission and sale of electricity and natural gas, is not required to decide in favor of the rule but, amid a recent FERC decision that drew industry criticism, must consider it.

Expediting the process or imposing an interim rule is generally limited to emergencies, the groups said. The Energy Department's letter to FERC does not even attempt to establish that an immediate threat to U.S. electricity reliability exists, they allege.

 

  • A coalition of energy industry groups asked regulators to reject a rule proposed by the U.S. Department of Energy on Friday.
  • The rule would bolster coal-fired and nuclear power plants by requiring wholesale markets to compensate them for certain attributes.
  • The groups say the Energy Department proposed "unreasonable timelines" for stakeholders to offer feedback on a rule with "significant ramifications for wholesale markets."

 

The groups cite a recent Energy Department report on grid reliability that concluded: "reliability is adequate today despite the retirement of 11 percent of the generating capacity available in 2002, as significant additions from natural gas, wind, and solar have come online since then."

The Department of Energy did not return a request for comment.

The Energy Department's rule marks a flashpoint in the battle between natural gas-fired and renewable energy and so-called baseload power sources like coal and nuclear.

Separately, coal and business groups have supported the EPA in litigation over the Affordable Clean Energy rule, as documented in legal challenges brought during the rule's defense.

Gas, wind and solar power have eaten into coal and nuclear's share of U.S. electric power generation in recent years. That is thanks to a boom in U.S. gas production that has pushed down prices, the rapid adoption of subsidized renewable energy and President Barack Obama's efforts to mitigate emissions from power plants, which the Trump administration has sought to replace with a tune-up as policies shift.

Electric power is priced in deregulated, wholesale markets in many parts of the country. Utilities typically draw on the cheapest power sources first.

Some worry that the retirement of coal-fired and nuclear power plants undermines the nation's ability to reliably and affordably deliver electricity to households and businesses.

President Donald Trump has vowed to revive the ailing coal industry, declaring an end to the 'war on coal' in public remarks. Trump, Perry and other administration officials reject the consensus among climate scientists that carbon emissions from sources like coal-fired plants are the primary cause of global warming.

Trump Is Seen Replacing Obama’s Power Plant Overhaul With a Tune-Up

Clean Power Plan Rollback signals EPA's shift to inside-the-fence efficiency at coal plants, emphasizing heat-rate improvements over sector-wide decarbonization, renewables, natural gas switching, demand-side efficiency, and carbon capture under Clean Air Act constraints.

 

Key Points

A policy shift by the EPA to replace broad emissions rules with plant-level efficiency standards, limiting CO2 cuts.

✅ Inside-the-fence heat-rate improvements at coal units

✅ Potential CO2 cuts limited to about 6% per plant

✅ Alternatives: fuel switching, renewables, carbon capture

 

President Barack Obama’s signature plan to reduce carbon dioxide emissions from electrical generation took years to develop and touched every aspect of power production and use, from smokestacks to home insulation.

The Trump administration is moving to scrap that plan and has signaled that any alternative it might adopt would take a much less expansive approach, possibly just telling utilities to operate their plants more efficiently.

That’s a strategy environmentalists say is almost certain to fall short of what’s needed.

The Trump administration is making "a wholesale retreat from EPA’s legal, scientific and moral obligation to address the threats of climate change," said former Environmental Protection Agency head Gina McCarthy, the architect of Obama’s Clean Power Plan.

President Donald Trump promised to rip up the initiative, echoing an end to the 'war on coal' message from his campaign, which mandated that states change their overall power mix, displacing coal-fired electricity with that from wind, solar and natural gas. The EPA is about to make it official, arguing the prior administration violated the Clean Air Act by requiring those broad changes to the electricity sector, according to a draft obtained by Bloomberg.

 

Possible Replacements

Later, the agency will also ask the public to weigh in on possible replacements. The administration will ask whether the EPA can or should develop a replacement rule -- and, if so, what actions can be mandated at individual power plants, though some policymakers favor a clean electricity standard to drive broader decarbonization.

 

Follow the Trump Administration’s Every Move

Such changes -- such as adding automation or replacing worn turbine seals -- would yield at most a 6 percent gain in efficiency, along with a corresponding fall in greenhouse gas emissions, according to earlier modeling by the Environmental Protection Agency and other analysts. That compares to the 32 percent drop in emissions by 2030 under Obama’s Clean Power Plan.

"In these existing plants, there’s only so many places to look for savings," said John Larsen, a director of the Rhodium Group, a research firm. "There’s only so many opportunities within a big spinning machine like that."

EPA Administrator Scott Pruitt outlined such an "inside-the-fence-line" approach in 2014, later embodied in the Affordable Clean Energy rule that industry groups backed, when he served as Oklahoma’s attorney general. Under his blueprint, states would set emissions standards after a detailed unit-by-unit analysis, looking at what reductions are possible given "the engineering limits of each facility."

The EPA has not decided whether it will promulgate a new rule at all, though it has also proposed new pollution limits for coal and gas plants in separate actions. In a forthcoming advanced notice of proposed rulemaking, the EPA will ask "what inside-the-fence-line options are legal, feasible and appropriate," according to a document obtained by Bloomberg.

Increased efficiency at a coal plant -- known as heat-rate improvement -- translates into fewer carbon-dioxide emissions per unit of electric power generated.

Under Obama, the EPA envisioned utilities would make some straightforward efficiency improvements at coal-fired power plants as the first step to comply with the Clean Power Plan. But that was expected to coincide with bigger, broader changes -- such as using more cleaner-burning natural gas, adding more renewable power projects and simply encouraging customers to do a better job turning down their thermostats and turning off their lights.

Obama’s EPA didn’t ask utilities to wring every ounce of efficiency they could out of coal-fired power plants because they saw the other options as cheaper. A plant-specific approach "would be grossly insufficient to address the public health and environmental impacts from CO2 emissions," Obama’s EPA said.

That approach might yield modest emissions reductions and, in a perverse twist, might event have the opposite effect. If utilities make coal plants more efficient -- thereby driving down operating costs -- they also make them more competitive with natural gas and renewables, "so they might run more and pollute more," said Conrad Schneider, advocacy director for the Clean Air Task Force.  

In a competitive market, any improvement in emissions produced for each unit of energy could be overwhelmed by an increase in electrical output, and debates over changes to electricity pricing under Trump and Perry added further uncertainty.

"A very minor heat rate improvement program would very likely result in increased emissions," Schneider said. "It might be worse than nothing."

Power companies want to get as much electricity as possible from every pound of coal, so they already have an incentive to keep efficiency high, said Jeff Holmstead, a former assistant EPA administrator now at Bracewell LLP. But an EPA regulation known as “new source review” has discouraged some from making those changes, for fear of triggering other pollution-control requirements, he said.

"If EPA’s replacement rule allows companies to improve efficiency without triggering new source review, it would make a real difference in terms of reducing carbon-dioxide emissions," Holmstead said.

 

Modest Impact

A plant-specific approach doesn’t have to mean modest impact.

"If you’re thinking about what can be done at the power plants by themselves, you don’t stop at efficiency tune-ups," said David Doniger, director of the Natural Resources Defense Council’s climate and clean air program. "You look at things like switching to natural gas or installing carbon capture and storage."

Requirements that facilities use carbon capture technology or swap in natural gas for coal could actually come close to hitting the same goals as in Obama’s Clean Power Plan -- if not go even further, Schneider said. They just would cost more.

The benefit of the Clean Power Plan "is that it enabled states to create programs and enabled companies to find a reduction strategy that was the most efficient and made the most sense for their own content," said Kathryn Zyla, deputy director of the Georgetown Climate Center. "And that flexibility was really important for the states and companies."

Some utilities, including Houston-based Calpine Corp., PG&E Corp. and Dominion Resources Inc., backed the Obama-era approach. And they are still pushing the Trump administration to be creative now.

"The Clean Power Plan achieved a thoughtful, balanced approach that gave companies and states considerable flexibility on how best to pursue that goal," said Melissa Lavinson, vice president of federal affairs and policy for PG&E’s Pacific Gas and Electric utility. “We look forward to working with the administration to devise an alternative plan for decarbonizing the U.S. economy."

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.
