Power plants for LNG supplies proposed

Rio Tinto waste heat-to-electricity initiative captures underground mining thermal energy at Resolution Copper, Arizona, converting it to renewable power for cooling systems and microgrids, advancing decarbonization, energy efficiency, and the miner's 2050 carbon-neutral goal.

Key Points

A program converting underground thermal energy into on-site electricity to cut emissions and support mine cooling.

✅ Captures low-grade heat from rock and geothermal water.

✅ Generates electricity for ventilation, refrigeration, microgrids.

✅ Scalable, safe, and grid- or storage-ready for peak demand.

The world’s second-largest miner, Rio Tinto announced that it is accepting proposals for solutions that transform waste heat into electricity for reuse from its underground operations.

In a press release, the company said this initiative is aimed at drastically reducing greenhouse gas emissions, even as energy-intensive projects like bitcoin mining operations expand, so that it can achieve its goal of becoming carbon neutral by 2050.

Initially, the project would be implemented at the Resolution copper mine in Arizona, which Rio owns together with BHP (ASX, LON: BHP). At this site, massive electrically-driven refrigeration and ventilation systems, aligned with broader electrified mining practices, are in charge of cooling the work environment because of the latent heat from the underground rock and groundwater. 

THE INITIATIVE IS AIMED AT REDUCING GREENHOUSE GAS EMISSIONS SO THAT RIO CAN ACHIEVE ITS GOAL OF BECOMING CARBON NEUTRAL BY 2050

“When operating, the Resolution copper mine will be a deep underground block cave mine some 7,000 feet (~2 kilometres) deep, with ambient air temperatures ranging between 168°F to 180°F (76°C to 82°C), conditions that, during heat waves, when bitcoin mining power demand can strain local grids, further heighten cooling needs, and underground water at approximately 194°F (90°C),” the media brief states.

“Rio Tinto is seeking solutions to capture and reuse the heat from underground, contributing towards powering the equipment needed to cool the operations. The solution to capture and convert this thermal energy into electrical energy, such as emerging thin-film thermoelectrics, should be safe, environmentally friendly and cost-effective.”

The miner also said that, besides capturing heat for reuse, the solution should generate electrical energy from low range temperatures below the virgin rock temperature and/or from the high thermal water coming from the underground rock, similar to using transformer waste heat for heating in the power sector. 

At the same time, the solution should be scalable and easily transported through the many miles of underground tunnels that will be built to ventilate, extract and move copper ore to the surface.

Rio requires proposals to offer the possibility of distributing the electrical energy generated back into the electrical grid from the mining operation or stored and used at a later stage when energy is required during peak use periods, especially as jurisdictions aim to use more electricity for heat in colder seasons.

Germany 2025 Energy Costs forecast electricity and heating price trends amid gas volatility, renewables expansion, grid upgrades, and policy subsidies, highlighting impacts on households, industries, efficiency measures, and the Energiewende transition dynamics.

Key Points

Electricity stabilizes, gas-driven heating stays high; renewables, subsidies, and efficiency measures moderate costs.

✅ Power prices stabilize above pre-crisis levels

✅ Gas volatility keeps heating bills elevated

✅ Subsidies and efficiency upgrades offset some costs

As Germany moves into 2025, the country is facing significant shifts in heating and electricity costs. With a variety of factors influencing energy prices, including geopolitical tensions, government policies, and the ongoing transition to renewable energy sources, consumers and businesses alike are bracing for potential changes in their energy bills. In this article, we will explore how heating and electricity costs are expected to evolve in Germany in the coming year and what that means for households and industries.

Energy Price Trends in Germany

In recent years, energy prices in Germany have experienced notable fluctuations, particularly due to the aftermath of the global energy crisis, which was exacerbated by the Russian invasion of Ukraine. This geopolitical shift disrupted gas supplies, which in turn affected electricity prices and strained local utilities across the country. Although the German government introduced measures to mitigate some of the price increases, many households have still felt the strain of higher energy costs.

For 2024, experts predict that electricity prices will likely stabilize but remain higher than pre-crisis levels. While electricity prices nearly doubled in 2022, they have gradually started to decline, and the market has adjusted to the new realities of energy supply and demand. Despite this, the cost of electricity is expected to stay elevated as Germany continues to phase out coal and nuclear energy while ramping up the use of renewable sources, which often require significant infrastructure investments.

Heating Costs: A Mixed Outlook

Heating costs in Germany are heavily influenced by natural gas prices, which have been volatile since the onset of the energy crisis. Gas prices, although lower than the peak levels seen in 2022, are still considerably higher than in the years before. This means that households relying on gas heating can expect to pay more for warmth in 2024 compared to previous years.

The government has implemented measures to cushion the impact of these increased costs, such as subsidies for vulnerable households and efforts to support energy efficiency upgrades. Despite these efforts, consumers will still feel the pinch, particularly in homes that use older, less efficient heating systems. The transition to more sustainable heating solutions, such as heat pumps, remains a key goal for the German government. However, the upfront cost of such systems can be a barrier for many households.

The Role of Renewable Energy and the Green Transition

Germany has set ambitious goals for its energy transition, known as the "Energiewende," which aims to reduce reliance on fossil fuels and increase the share of renewable energy sources in the national grid. In 2024, Germany is expected to see further increases in renewable energy generation, particularly from wind and solar power. While this transition is essential for reducing carbon emissions and improving long-term energy security, the shift comes with its own challenges already documented in EU electricity market trends reports.

One of the main factors influencing electricity costs in the short term is the intermittency of renewable energy sources. Wind and solar power are not always available when demand peaks, requiring backup power generation from fossil fuels or stored energy. Additionally, the infrastructure needed to accommodate a higher share of renewables, including grid upgrades and energy storage solutions, is costly and will likely contribute to rising electricity prices in the near term.

On a positive note, Germany's growing investment in renewable energy is expected to make the country less reliant on imported fossil fuels, particularly natural gas, which has been a major source of price volatility. Over time, as the share of renewables in the energy mix grows, the energy system should become more stable and less susceptible to geopolitical shocks, which could lead to more predictable and potentially lower energy costs in the long run.

Government Interventions and Subsidies

To help ease the burden on consumers, the German government has continued to implement various measures to support households and businesses. One of the key programs is the reduction in VAT (Value Added Tax) on electricity, which has been extended in some regions. This measure is designed to make electricity more affordable for all households, particularly those on fixed incomes facing EU energy inflation pressures that have hit the poorest hardest.

Moreover, the government has been providing financial incentives for households and businesses to invest in energy-efficient technologies, such as insulation and energy-saving heating systems, complementing the earlier 200 billion euro energy shield announced to buffer surging prices. These incentives are intended to reduce overall energy consumption, which could offset some of the rising costs.

The outlook for heating and electricity costs in Germany for 2024 is mixed, even as energy demand hit a historic low amid economic stagnation. While some relief from the extreme price spikes of 2022 may be felt, energy costs will still be higher than they were in previous years. Households relying on gas heating will likely see continued elevated costs, although those who invest in energy-efficient solutions or renewable heating technologies may be able to offset some of the increases. Similarly, electricity prices are expected to stabilize but remain high due to the country’s ongoing transition to renewable energy sources.

While the green transition is crucial for long-term sustainability, consumers must be prepared for potentially higher energy costs in the short term. Government subsidies and incentives will help alleviate some of the financial pressure, but households should consider strategies to reduce energy consumption, such as investing in more efficient heating systems or adopting renewable energy solutions like solar panels.

As Germany navigates these changes, the country’s energy future will undoubtedly be shaped by a delicate balance between environmental goals and the economic realities of transitioning to a greener energy system.

Duke Energy zero-coal 2050 plan outlines a decarbonized energy mix, aligning with Paris goals, cutting greenhouse gas emissions, driven by investor pressure, shifting to natural gas, extending nuclear power, and phasing out coal.

Key Points

An investor-driven scenario to end coal by 2050, shift to natural gas, extend nuclear plants, and manage climate risk.

✅ Eliminates coal from the generation mix by 2050

✅ Prioritizes natural gas transitions without CCS breakthroughs

✅ Extends nuclear plant licenses to limit carbon emissions

One of America’s largest utility companies, Duke Energy, is set to release a report later this month that sketches a drastically changed electricity mix in a carbon-constrained future.

The big picture: Duke is the latest energy company to commit to releasing a report about climate change in response to investor pressure, echoing shifts such as Europe's oil majors going electric across the sector, conveyed by non-binding but symbolically important shareholder resolutions. Duke provides electricity to more than seven million customers in the Carolinas, the Midwest and Florida.

Gritty details: The report is expected to find that coal, currently 33% of Duke’s mix, gone entirely from its portfolio by 2050 in a future scenario where the world has taken steps to cut greenhouse gas emissions, and where global coal-fired electricity use is falling markedly, to a level consistent with keeping global temperatures from rising two degrees Celsius. That’s the big ambition of the 2015 Paris climate deal, but the current commitments aren’t close to reaching that.

What they're saying: “What’s difficult about this is we are trying to overlay what we understand currently about technology,” Lynn Good, Duke CEO, told Axios in an interview on the sidelines of a major energy conference here.

She went on to say that this scenario of zero coal by 2050 doesn’t assume any breakthroughs in technology that captures carbon emissions from coal-fired power plants. “We don’t see that technology today, and we need to make economic decisions to get those units moving and replacing them with natural gas.”

Good also stressed the benefits of its several nuclear power plants, highlighting the role of sustaining U.S. nuclear power in decarbonization, which emit no carbon emissions. She said Duke isn’t considering investing in new nuclear plants, but plans to seek federal relicensing of current plants.

“If I turn them off, the resource that would replace them today is natural gas, so carbon will go up,” Good said. “Our objective is to continue to keep those plants as long as possible.”

What’s next: A spokesman said the other details of their 2050 scenario estimates will be available when the report is officially released by month’s end.

Axios reports that Duke Energy will release a report later this month that detail the utility's efforts to mitigate climate change risks and plan carbon-free electricity investments across its operations. The report includes a scenario that eliminates coal entirely from the company's power mix by 2050. Coal currently makes up about a third of Duke's generation.

Duke CEO Lynn Good told the news outlet the scenario ending coal-fired generation assumes no technological advances in emissions capture, seemingly leaving open the possibility.

Last year, a report by the Union of Concerned Scientists concluded one in four of the remaining operating coal-fired plants in the U.S. are slated for closure or conversion to natural gas, amid falling power-sector carbon emissions across the country. Duke's report is expected to be released by the end of the month.

Duke's report on its carbon plans comes at the behest of shareholders, a trend utility companies have seen growing among investors who are increasingly concerned about companies' sustainability and their financial exposure to climate policy.

Last year, a majority of shareholders of Pennsylvania utility PPL Corp. called on company management to publish a report on how climate change policies and technological innovations will affect the company's bottom line. Almost 60% of shareholders voted in favor of the non-binding proposal.

The vote, reportedly a first for the power sector, followed a similar decision by shareholders of Occidental Petroleum, which was supported by about 66% of shareholders.

Duke's Good told Axios that right now the utility does not see the coal technology on the horizon that would keep it operating plants. “We don't see that technology today, and we need to make economic decisions to get those units moving and replacing them with natural gas," Good said. However, it does not mean the utility is making near-term efforts to erase coal from its power mix. However, some utilities are taking those steps as they prepare for en energy landscape with more carbon regulations.

In addition to the 25% of coal plants heading for closure or conversion, the UCS report also said that another 17% of the nation’s operating coal plants are uneconomic compared with natural gas-fired generation, and could face retirement soon. But there is plenty of ongoing research into "clean coal" possibilities, and the federal government has expressed an interest in smaller, modular coal units.

France-Germany Energy Solidarity underscores EU energy crisis cooperation: gas supply swaps, electricity imports, price cap talks, and curbs on speculation as Russian pipeline flows halt and winter demand rises across the bloc.

Key Points

A pact where France sends gas to Germany as Germany supplies power, bolstering EU cooperation and winter security.

✅ Gas to Germany; power to France amid nuclear outages.

✅ EU price cap, anti-speculation, joint gas purchasing.

✅ No new Spain-France pipeline unless case improves.

France will send gas to Germany if needed while Germany stands ready to provide it with electricity, President Emmanuel Macron said on Monday, saying this showcased European solidarity in the face of the energy crisis stemming from the war in Ukraine, which many view as a wake-up call to ditch fossil fuels across the bloc.

European gas prices surged, share prices slid and the euro sank on Monday after Russia stopped pumping gas via a major supply route, and Germany's 200 billion euro package sought to cushion the blow, in another warning to the 27-nation EU as it scrambled to respond to the crisis ahead of winter. read more

"Germany needs our gas and we need power from the rest of Europe, notably Germany," France's president told a news conference as EU electricity reform remains under debate following a phone call with German Chancellor Olaf Scholz.

The necessary connections for France to deliver gas to Germany when needed would be finalised in the coming weeks, he said, adding that France, which had long been a net exporter of electricity, will need help from its neighbours because of technical problems its nuclear plants face. read more

Macron, however, said that he did not understand demand for a third gas link between France and Spain, rejecting calls to increase capacity with a new pipeline.

He added he was open to changing his mind on that point, especially as Germany's utility troubles deepen, should Scholz or Prime Minister Pedro Sanchez argue convincingly for it.

Ahead of a meeting on Friday of EU energy ministers, Macron said France was in favour of buying gas at a European rather than a national level, as emergency electricity measures are weighed, and called for European Union measures to control energy prices.

He said it was necessary to act against speculation on energy prices at EU level, as the EU outlines possible gas price cap strategies for discussion, and also said France was in favour of putting a cap on the price of pipeline Russian gas.

Macron also repeated calls for all to turn down air conditioners when it's hot and to limit heating to 19 degrees Celsius this winter, noting that rolling back electricity prices is tougher than it appears this year.

"Everyone has to do their bit," he said.

Site C Dam Controversy highlights Peace River risks, BC Hydro claims, Indigenous rights under Treaty 8, environmental assessment findings, and potential impacts to agriculture and the Peace-Athabasca Delta across Alberta and the Northwest Territories.

Key Points

Debate over BC Hydro's Site C dam: clean energy vs Indigenous rights, Peace-Athabasca Delta impacts, and agriculture.

✅ Potential drying of Peace-Athabasca Delta and wildlife habitat

✅ Treaty 8 rights and First Nations legal challenges

✅ Loss of prime Peace Valley farmland; alternatives in renewables

One of the leading opponents of the Site C dam in northeastern B.C. is sharing her concerns with northerners this week.

Proponents of the Site C dam say it will be a cost-effective source of clean electricity, even as a major Alberta wind farm was scrapped elsewhere in Canada, and that it will be able to produce enough energy to power the equivalent of 450,000 homes per year in B.C. But a number of Indigenous groups and environmentalists are against the project.

Wendy Holm is an economist and agronomist who did an environmental assessment of the dam focusing on its potential impacts on agriculture.

On Tuesday she spoke at a town hall presentation in Fort Smith, N.W.T., organized by the Slave River Coalition. She is also speaking at an event in Yellowknife on Friday, as small modular reactors in Yukon receive study as a potential long-term option.

Worried about downstream impacts, Northern leaders urge action on Site C dam

"I learned that people outside of British Columbia are as concerned with this dam as we are," Holm said.

"There's just a lot of concern with what's happening on the Peace River and this dam and the implications for Alberta, where hydro's share has diminished in recent decades, and the Northwest Territories."

If completed, BC Hydro's Site C energy project will be the third dam on the Peace River in northeast B.C. and the largest public works project in B.C. history. The $10.7-billion project was approved by both the provincial and federal governments as B.C. moves to streamline clean energy permitting for future projects.

Amy Lusk, co-ordinator of the Slave River Coalition, said many issues were discussed at the town hall, but she also left with a sense of hope.

"I think sometimes in our little corner of the world, we are up against so much when it comes to industrial development and threats to our water," she said.

"To kind of take away that message of, this is not a done deal, and that we do have a few options in place to try and stop this and not to lose hope, I think was a very important message for the community."

Drying of the Peace-Athabasca Delta

Holm said her main concern for the Northwest Territories is how it could affect the Peace-Athabasca Delta. She said the two dams already on the river are responsible for two-thirds of the drying that's happening in the delta.

"These are very real issues and very present in the minds of northerners who want to stay connected to a traditional lifestyle, want to have access to those wild foods," she said.

Lusk said northerners are fed up with defending waters "time after time after time."

BC Hydro, however, said studies commissioned during the environmental assessment of Site C show the project will have no measurable effect on the delta, which is located 1,100 kilometres away.

Holm said the fight against the Site C dam is also important when it comes to First Nations treaty rights.

The West Moberly and Prophet River First Nations applied for an injunction to halt construction on Site C, as well as a treaty infringement lawsuit against the B.C. government. They argue the dam would cause irreparable harm to their territories and way of life, which are rights protected under Treaty 8.

Agricultural land

While the project is located in B.C., Holm said its impacts on prime horticulture land would also affect northerners, something that's important given issues of food security and nutrition.

"This is some of the best agriculture land in all of Canada," she said of the Peace Valley.

According to BC Hydro, around 2.6 million hectares of land in the Peace agricultural region would remain available for agricultural production while 3,800 hectares would be unavailable. It has also proposed a number of mitigation efforts, including a $20-million agricultural compensation fund.

Holm said renewable energy, including tidal energy for remote communities, will be cheaper and less destructive than the dam, and there's a connection between the dams on the Peace River and water sharing with the U.S.

"When you run out of water there's nothing else you can use. You can't use orange juice to irrigate your fields or to run your industries or to power your homes," she said.

Iran Electricity Exports to Iraq address power shortages and blackouts, supplying 1,200-1,500 MW and gas for 2,500 MW, amid sanctions, aging grid losses, rising peak demand, and TAVANIR plans to expand cross-border energy capacity.

Key Points

Energy flows from Iran supply Iraq with 1,200-1,500 MW plus gas yielding 2,500 MW, easing shortages and blackouts.

✅ 1,200-1,500 MW direct power; gas adds 2,500 MW generation

✅ Iraq exempt on Iranian gas, but faces US pressure

✅ Aging grid loses 25%; $30B upgrades needed

“Iran exports 1,200 megawatts to 1,500 megawatts of electricity to Iraq per day, reflecting broader regional power trade dynamics, as Iraq is dealing with severe power shortages and frequent blackouts,” Hamid Hosseini said.

As he added, Iran also exports 37 million to 38 million cubic meters of gas to the country, much of it used in combined-cycle power plants to save energy and boost generation.

On September 11, Iraq’s electricity minister, Luay al Khateeb, said the country needs Iranian gas to generate electricity for the next three or four years, as energy cooperation discussions continue between Baghdad and Tehran.

Iraq was exempted from sanctions concerning Iranian gas imports; however, the U.S. has been pressing all countries to stop trading with Tehran.

Iraq's population has been protesting to authorities over power cuts. Iran exports 1,200 megawatts of direct power supplies and its gas is converted into 2,500 MW of electricity. According to al Khateeb, the current capacity is 18,000 MW, with peak demand of 25,000 MW possible during the hot summer months when consumption surges, a figure that rises every year.

Any upgrades would need investment of at least $30 billion, with grid rehabilitation efforts underway to modernize infrastructure, as the grid is 50 years old and loses 25 percent of its capacity due to Isis attacks.

In late July, Managing Director of Gharb (West) Regional Electricity Company Ali Asadi said Iran has high capacity and potential to export electricity up to twofold of the current capacity to neighboring Iraq, as it eyes transmitting electricity to Europe to serve as a regional hub as well.

He pointed to the new strategy of Iran Power Generation, Transmission & Distribution Management Company (TAVANIR) for increasing electricity export to neighboring Iraq and reiterated, “the country enjoys high potential to export 1,200 megawatts electricity to neighboring Iraq,” while Iraq is also exploring nuclear power plants to tackle electricity shortages.
