Climate taxes, not cap and trade markets alone, will lead to the vast technological changes the world's energy system needs to fight global warming, a top U.S. economist said.

Cap and trade has emerged as the dominant attempt to slow global warming. Global deals in permits to emit greenhouse gas emissions have hit nearly $65 billion a year. The European Union, under the Kyoto Protocol, has embraced cap and trade since 2005 and voluntary markets have developed in the United States, the developed world's top carbon polluter.

But a straight carbon tax on energy production — at an oil wellhead or refinery for instance — would be simpler and cheaper than putting a cap on tens of thousands of polluters, Jeffrey Sachs, a special advisor to the U.N. secretary general and director of the Earth Institute at Columbia University told a panel.

As the world prepares to form a successor agreement to the Kyoto Protocol by the end of next year, focus is sharpening on how well cap and trade markets are fighting emissions.

Carbon taxes would quickly cut emissions across all sectors of the economy, including vehicles and manufacturing, said Sachs. It could also be more efficient than spreading the trade of permits across the financial system.

"Having a lot of people engineer financial instruments for carbon when there are much more direct ways to do this strikes me as not really a great investment," Sachs said.

"I'm also not so keen on sending our best and brightest off to do more financial engineering," he said. "I think the kind of (financial) meltdown we have right is a little bit of an example of how we've taken a generation of young people and put them in tasks that don't really solve social problems."

Yvo de Boer, the U.N. climate chief, told the panel he doubted voters in the United States and other countries would accept new taxes.

Sachs admitted that the United States is "neurotic" about new taxes, but said they would be the best way to fund research and development and subsidies for big low-carbon energy projects such as nuclear plants and transmission systems to bring solar power from the Southwest and wind power from the Great Plains states to cities on the coasts.

Sachs criticized one of the mainstays of climate trade that has developed in the European Union. Under the Kyoto Protocol the Clean Development Mechanism allows rich countries to offset their carbon footprints by investing in clean energy projects like small wind farms or hydroelectric dams in developing countries.

"Things like the CDM are just unfortunately very marginal small tools that aren't going to change the broad framework of how energy is produced and how technology is developed and distributed," said Sachs.

De Boer said the CDM has met its goals but that a range of tools could be developed to improve it. Investments could be widened, for instance, to improve whole sectors of developing countries, such as mass transit systems in large cities.

Berlin Geothermal Plant in El Salvador Set to Launch This Year

El Salvador Geothermal Expansion boosts renewable energy with a 7 MW Berlin binary ORC plant, upgrades at Ahuachapan, and pipeline projects, strengthening clean power capacity, grid reliability, and sustainable growth in Central America.

 

Key Points

A national push adding binary-cycle capacity at Berlin and Ahuachapan, boosting geothermal supply and advancing sites.

✅ 7 MW Berlin binary ORC plant entering service.

✅ Ahuachapan upgrade adds 2 MW, total geothermal 204 MW.

✅ Next: Chinameca, San Miguel, San Vicente, World Bank backed.

 

El Salvador is set to expand its renewable energy capacity with the inauguration of the 7-MW Berlin binary geothermal power plant, slated to go online later this year. This new addition marks a significant milestone in the country’s geothermal energy development, highlighting its commitment to sustainable energy solutions. The plant, which has already been installed and is currently undergoing testing, is expected to boost the nation’s geothermal capacity, contributing to its growing renewable energy portfolio.

The Role of Geothermal Energy in El Salvador’s Energy Mix

Geothermal energy plays a pivotal role in El Salvador's energy landscape. With the combined output from the Ahuachapan and Berlin geothermal plants, geothermal energy now accounts for about 21% of the country's net electricity supply. This makes geothermal the second-largest source of energy generation in El Salvador, underscoring its importance as a reliable and sustainable energy resource alongside emerging options like advanced nuclear microreactor technologies in the broader low-carbon mix.

In addition to the Berlin plant, El Salvador has made significant improvements to its Ahuachapan geothermal power plant. Recent upgrades have increased its generation capacity by 2 MW, further enhancing the country’s geothermal energy output. Together, the Ahuachapan and Berlin plants bring the total installed geothermal capacity to 204 MW, positioning El Salvador as a regional leader in geothermal energy development.

The Berlin Binary Geothermal Plant: A Technological Milestone

The Berlin binary geothermal power plant is especially noteworthy for several reasons. It is the first geothermal power plant to be constructed in El Salvador since 2007, marking a significant step in the country's ongoing efforts to expand its renewable energy infrastructure while reinforcing attention to risk management in light of Hawaii geothermal safety concerns reported elsewhere. The plant utilizes a binary cycle geothermal system, which is known for its efficiency in extracting energy from lower temperature geothermal resources, making it an ideal solution for regions like Berlin, where geothermal resources are abundant but at lower temperatures.

The plant was built by Turboden, an Italian company specializing in organic Rankine cycle (ORC) technology. The binary cycle system operates by transferring heat from the geothermal fluid to a secondary fluid, which then drives a turbine to generate electricity. This system allows for the efficient use of geothermal resources that might otherwise be too low in temperature for traditional geothermal plants, enabling pairing with thermal storage demonstration solutions to optimize output.

Future Geothermal Developments in El Salvador

El Salvador is not stopping with the Berlin geothermal plant. The country is actively working on other geothermal projects, including those in Chinameca, San Miguel, and San Vicente. These developments are expected to add 50 MW of additional capacity in their first phase, reflecting a broader shift as countries pursue hydrogen-ready power plants to reduce emissions, with a second phase, supported by the World Bank, planned to add another 100 MW.

The Chinameca, San Miguel, and San Vicente projects represent the next wave of geothermal development in El Salvador. When completed, these plants will significantly increase the country’s geothermal capacity, further diversifying its energy mix and reducing reliance on fossil fuels, and will require ongoing grid upgrades, a task complicated elsewhere by Germany grid expansion challenges highlighted in Europe.

International Support and Collaboration

El Salvador’s geothermal development efforts are supported by various international partners, including the World Bank, which has been instrumental in financing the expansion of geothermal projects, as utilities such as SaskPower geothermal plans in Canada explore comparable pathways. This collaboration highlights the global recognition of El Salvador’s potential in geothermal energy and its efforts to position itself as a hub for geothermal energy development in Central America.

Additionally, the country’s expertise in geothermal energy, especially in binary cycle technology, has attracted international attention. El Salvador’s progress in the geothermal sector could serve as a model for other countries in the region that are looking to harness their geothermal resources to reduce energy costs and promote sustainable energy development.

The upcoming launch of the Berlin binary geothermal power plant is a testament to El Salvador’s commitment to sustainable energy. As the country continues to expand its geothermal capacity, it is positioning itself as a leader in renewable energy in the region. The binary cycle technology employed at the Berlin plant not only enhances energy efficiency but also demonstrates El Salvador’s ability to adapt and innovate within the renewable energy sector.

With the continued development of projects in Chinameca, San Miguel, and San Vicente, and ongoing international collaboration, El Salvador’s geothermal energy sector is set to play a crucial role in the country’s energy future. As global demand for clean energy grows, exemplified by U.S. solar capacity additions this year, El Salvador’s investments in geothermal energy are helping to build a more sustainable, resilient, and energy-independent future.

SaskPower eyes buying $300M worth of electricity from Flying Dust First Nation

SaskPower-Flying Dust flare gas power deal advances a 20 MW, 20-year Power Purchase Agreement, enabling grid supply from FNPA-backed generation, supporting renewable strategy, lower carbon footprint targets, and First Nation economic development in Saskatchewan.

 

Key Points

A 20 MW, 20-year PPA converting flare gas to grid power, with SaskPower buying from Flying Dust First Nation via FNPA.

✅ 20 MW of flare gas generation linked to Saskatchewan's grid

✅ 20-year term; about $300M total value to SaskPower

✅ FNPA-backed project; PPA targeted in 6-12 months

 

An agreement signed between SaskPower, which reported $205M income in 2019-20, and Flying Dust First Nation is an important step toward a plan that could see the utility buy $300 million worth of electricity from Flying Dust First Nation, according to Flying Dust's chief.

"There's still a lot of groundwork that needs to be done before we get building but you know we're a lot closer today with this signing," Jeremy Norman told reporters Friday.

Norman's community was assisted by the First Nations Power Authority (FNPA), a non-profit that helps First Nations get into the power sector, with examples like the James Bay project showing what Indigenous ownership can achieve.

The agreement signed Friday says SaskPower will explore the possibility of buying 20 megawatts of flare gas power from FNPA, which it will look to Flying Dust to produce.

20-year plan

The proposed deal would span 20 years and cost SaskPower around $300 million over those years, as the utility also explores geothermal power to meet 2030 targets.

The exact price would be determined once a price per metawatt is brought forward.

"We won't be able to do this ourselves," Norman said.

Flare gas power generation works by converting flares from the oil and gas sector into electricity. Under this plan, SaskPower would take the electricity provided by Flying Dust and plug it into the provincial power grid, complementing a recent move to buy more power from Manitoba Hydro to support system reliability.

"This is a great opportunity as we advance our renewable strategy, including progress on doubling renewables by 2030, and try to achieve a lower carbon footprint by 2030 and beyond," Marsh said.

Ombudsman report details dispute between senior with breathing disorder, SaskPower

Norman said the business deal presents an opportunity to raise money to reinvest into the First Nation for things like more youth programming.

For the next steps, both parties will need to sign a power purchase agreement that spells out the exact prices for the power generation.

Marsh expects to do so in the next six to 12 months, with development of the required infrastructure to take place after that.

PG&E Rates Set to Stabilize in 2025

PG&E 2024 Rate Hikes signal sharp increases to fund wildfire safety, infrastructure upgrades, and CPUC-backed reliability, with rates expected to stabilize in 2025, affecting rural residents, businesses, and high-risk zones across California.

 

Key Points

PG&E’s 2024 hikes fund wildfire safety and grid upgrades, with pricing expected to stabilize in 2025.

✅ Driven by wildfire safety, infrastructure, and reinsurance costs

✅ Largest impacts in rural, high-risk zones; business rates vary

✅ CPUC oversight aims to ensure necessary, justified investments

 

Pacific Gas and Electric (PG&E) is expected to implement a series of rate hikes that, amid analyses of why California electricity prices are soaring across the state, will significantly impact California residents. These increases, while substantial, are anticipated to be followed by a period of stabilization in 2025, offering a sense of relief to customers facing rising costs.

PG&E, one of the largest utility providers in the state, announced that its 2024 rate hikes are part of efforts to address increasing operational costs, including those related to wildfire safety, infrastructure upgrades, and regulatory requirements. As California continues to face climate-related challenges like wildfires, utilities like PG&E are being forced to adjust their financial models to manage the evolving risks. Wildfire-related liabilities, which have plagued PG&E in recent years, play a significant role in these rate adjustments. In response to previous fire-related lawsuits, including a bankruptcy plan supported by wildfire victims that reshaped liabilities, and the increased cost of reinsurance, PG&E has made it clear that customers will bear part of the financial burden.

These rate hikes will have a multi-faceted impact. Residential users, particularly those in rural or high-risk wildfire zones, will see some of the largest increases. Business customers will also be affected, although the adjustments may vary depending on the size and energy consumption patterns of each business. PG&E has indicated that the increases are necessary to secure the utility’s financial stability while continuing to deliver reliable service to its customers.

Despite the steep increases in 2024, PG&E's executives have assured that the company's pricing structure will stabilize in 2025. The utility has taken steps to balance the financial needs of the business with the reality of consumer affordability. While some rate hikes are inevitable given California's regulatory landscape and climate concerns, PG&E's leadership believes the worst of the increases will be seen next year.

PG&E’s anticipated stabilization comes after a year of scrutiny from California regulators. The California Public Utilities Commission (CPUC) has been working closely with PG&E to scrutinize its rate request and ensure that hikes are justifiable and used for necessary investments in infrastructure and safety improvements. The CPUC’s oversight is especially crucial given the company’s history of safety violations and the public outrage over past wildfire incidents, including reports that its power lines may have sparked fires in California, which have been linked to PG&E’s equipment.

The hikes, though significant, reflect the broader pressures facing utilities in California, where extreme weather patterns are becoming more frequent and intense due to climate change. Wildfires, which have grown in severity and frequency in recent years, have forced PG&E to invest heavily in fire prevention and mitigation strategies, including compliance with a judge-ordered use of dividends for wildfire mitigation across its service area. This includes upgrading equipment, inspecting power lines, and implementing more rigorous protocols to prevent accidents that could spark devastating fires. These investments come at a steep cost, which PG&E is passing along to consumers through higher rates.

For homeowners and businesses, the potential for future rate stabilization offers a glimmer of hope. However, the 2024 increases are still expected to hit consumers hard, especially those already struggling with high living costs. The steep hikes have prompted public outcry, with calls for action as bills soar amplifying advocacy group arguments that utilities should absorb more of the costs related to climate change and fire prevention instead of relying on ratepayers.

Looking ahead to 2025, the expectation is that PG&E’s rates will stabilize, but the question remains whether they will return to pre-2024 levels or continue to rise at a slower rate. Experts note that California’s energy market remains volatile, and while the rates may stabilize in the short term, long-term cost management will depend on ongoing investments in renewable energy sources and continued efforts to make the grid more resilient to climate-related risks.

As PG&E navigates this challenging period, the company’s commitment to transparency and working with regulators will be crucial in rebuilding trust with its customers. While the immediate future may be financially painful for many, the hope is that the utility's focus on safety and infrastructure will lead to greater long-term stability and fewer dramatic rate increases in the years to come.

Ultimately, California residents will need to brace for another tough year in terms of utility costs but can find reassurance that PG&E’s rate increases will eventually stabilize. For those seeking relief, there are ongoing discussions about increasing energy efficiency, exploring renewable energy alternatives, and expanding assistance programs for lower-income households to help mitigate the financial strain of these price hikes.

Ontario Energy Board Sets New Electricity Rate Plan Prices and Support Program Thresholds

OESP Eligibility 2024 updates Ontario electricity affordability: TOU, Tiered, Ultra-Low-Overnight price plans, online bill calculator, higher income thresholds, monthly credits for low-income households, and a winter disconnection ban for residential customers.

 

Key Points

Raises income thresholds and credits to help low-income Ontarians cut electricity costs and choose suitable price plans.

✅ TOU, Tiered, and ULO price plans with online bill calculator

✅ Income eligibility thresholds raised up to 35% on March 1, 2024

✅ Winter disconnection ban for residences: Nov 15, 2023 to Apr 30, 2024

 

Residential, small business and farm customers can choose their price plan, either Time-Of-Use (TOU), Tiered or the ultra-low overnight rates price plan available to many customers. The OEB has an online bill calculator to help customers who are considering a switch in price plans and monitoring changes for electricity consumers this year. 

The Government of Ontario announced on Friday, October 19, 2023, that it is raising the income eligibility thresholds that enable Ontarians to qualify for the Ontario Electricity Support Program (OESP) by up to 35 percent. OESP is part of Ontario’s energy affordability framework and other support for electric bills meant to reduce the cost of electricity for low-income households by applying a monthly credit directly on to electricity bills.. The higher income eligibility thresholds will begin on March 1, 2024.

The amount of OESP bill credit is determined by the number of people living in a home and the household’s combined income, and can help offset typical bill increases many customers experience. The current income thresholds cap income eligibility at $28,000 for one-person households and $52,000 for five-person households, and temporary measures like the off-peak price freeze have also influenced bills in recent periods.

The new income eligibility thresholds, which will be in effect beginning March 1, 2024, will allow many more families to access the program as rates are about to change across Ontario.

In addition, under the OEB’s winter disconnection ban, which follows the Nov. 1 rate increase, electricity distributors cannot disconnect residential customers for non-payment from November 15, 2023, to April 30, 2024.

Ontario government wants new gas plants to boost electricity production

Ontario Gas Plant Expansion aims to boost grid reliability as nuclear refurbishments proceed, using natural gas to meet electricity demand, despite critics urging renewables, energy storage, and efficiency to reduce carbon emissions, protecting investment growth.

 

Key Points

Ontario plan to expand gas plants for reliability during nuclear outages, sparking debate on emissions and clean options.

✅ IESO data: gas share rose from 4% (2017) to 10.4% (2022).

✅ Government cites nuclear refurbishments and demand growth.

✅ Critics propose storage, wind, solar, and efficiency.

 

The Ontario government is preparing to expand gas-fired power plants in Ontario; a move critics say will make the province's electricity system dirtier and could eventually leave taxpayers on the hook.

The province is currently soliciting bids for additional gas-fired electricity generation, which means new gas plants get built, or existing gas plants get expanded. 

It's poised to be Ontario's biggest increase in the gas-fired power supply in more than a decade since the previous Liberal government scrapped two gas plants, in Mississauga and Oakville, at a cost the auditor general pegged at around $1 billion. 

Doug Ford's energy minister, Todd Smith, says Ontario needs gas plants now to help meet an expected surge in demand for electricity as the province faces a supply shortfall in the coming years and to provide power while some units of the province's nuclear stations are down for refurbishment. 

"It's really important to have natural gas as an insurance policy to keep the lights on and provide the reliability that we need," Smith said in an interview. 

"We need natural gas for the short term, especially to get us through these refurbishments."

The portion of Ontario's electricity supply that comes from natural gas matters for the environment and the province's economy. Manufacturing companies increasingly seek clean power that emits as little carbon dioxide as possible. 

The portion of Ontario's electricity supply that comes from natural gas matters for the environment and the province's economy. Manufacturing companies increasingly seek a power supply that emits as little carbon dioxide as possible. 

Increasing the amount of gas-fired generation in the electricity system puts Ontario's ability to attract such investments at risk as it complicates balancing demand and emissions across the grid, says Evan Pivnick, program manager with Clean Energy Canada, a think tank. 

"Building new natural gas (power plants) in Ontario today should be seen as an absolute last resort for meeting our energy needs," said Pivnick in an interview. 

Ontario's electricity system has among the lowest rates of CO2 emissions in North America, with roughly half of the annual supply provided by nuclear power, one-quarter from hydro dams, and one-tenth from wind turbines. 

However, Ontario's gas plants have produced a growing amount of electricity in recent years, despite an early report exploring a gas halt by the minister, and that trend will continue if new gas plants are built. 

In 2017, gas- and oil-fired generation provided just four percent of Ontario's electricity supply, according to figures from the provincial agency that manages the grid, the Independent Electricity System Operator (IESO). 

By 2022, that figure reached 10.4 percent. 

Ontario doesn't need new gas plants to meet the electricity demand, says Bryan Purcell, vice president of policy and programs at The Atmospheric Fund. This agency invests in low-carbon projects in the Greater Toronto and Hamilton Area. 

"We're quite concerned about where Ontario's electric grid is going," said Purcell. "Thankfully, there's still time to adjust course and look at other options." 

According to Purcell and Pivnick, those options to avoid gas could include power storage (in which excess generated energy is stored for later use when electricity demand rises), wind and solar projects, or energy efficiency and conservation programs.

Ireland goes 25 days without using coal to generate electricity

Ireland Coal-Free Electricity Record: EirGrid reports 25 days without coal on the all-island grid, as wind power, renewables, and natural gas dominated generation, cutting CO2 emissions, with Moneypoint sidelined by market competitiveness.

 

Key Points

It is a 25-day period when the grid used no coal, relying on gas and renewables to reduce CO2 emissions.

✅ 25 days coal-free between April 11 and May 7

✅ Gas 60%, renewables 30% of generation mix

✅ Eurostat: 6.8% drop in Ireland's CO2 emissions

 

The island of Ireland has gone a record length of time without using coal-fired electricity generation on its power system, Britain's week-long coal-free run providing a recent comparator, Eirgrid has confirmed.

The all-island grid operated without coal between April 11th and May 7th – a total of 25 days, it confirmed. This is the longest period of time the grid has operated without coal since the all-island electricity market was introduced in 2007, echoing Britain's record coal-free stretch seen recently.

Ireland’s largest generating station, Moneypoint in Co Clare, uses coal, with recent price spikes in Ireland fueling concerns about dispatchable capacity, as do some of the larger generation sites in Northern Ireland.

The analysis coincides with the European statistics agency, Eurostat publishing figures showing annual CO2 emissions in Ireland fell by 6.8 per cent last year; partly due to technical problems at Moneypoint.

Over the 25-day period, gas made up 60 per cent of the fuel mix, while renewable energy, mainly wind, accounted for 30 per cent, echoing UK wind surpassing coal in 2016 across the market. Coal-fired generation was available during this period but was not as competitive as other methods.

EirGrid group chief executive Mark Foley said this was “a really positive development” as coal was the most carbon intense of all electricity sources, with its share hitting record lows in the UK in recent years.

“We are acutely aware of the challenges facing the island in terms of meeting our greenhouse gas emission targets, mindful that low-carbon generation stalled in the UK in 2019, through the deployment of more renewable energy on the grid,” he added.

Last year 33 per cent of the island’s electricity came from renewable energy sources, German renewables surpassing coal and nuclear offering a parallel milestone, a new record. Coal accounted for 9 per cent of electricity generation, down from 12.9 per cent in 2017.
