Over 30% of Global Electricity from Renewables

Global Renewable Electricity Milestone signals solar, wind, hydro, and geothermal surpass 30% of power generation, driven by falling costs, battery storage, smart grids, and ambitious policy targets that strengthen energy security and decarbonization.

 

Key Points

It marks renewables exceeding 30% of global power, enabled by cheaper tech, storage, and strong policy.

✅ Costs of solar and wind fall, boosting competitiveness

✅ Storage and smart grids improve reliability and flexibility

✅ Policies target decarbonization while ensuring just transition

 

A recent report by the energy think tank Ember marks a significant milestone in the global energy transition. For the first time ever, according to their analysis, renewable energy sources like solar, wind, hydro, and geothermal now account for more than 30% of the world's electricity generation, a milestone echoed by wind and solar growth globally. This achievement signifies a pivotal shift towards a cleaner and more sustainable energy future.

The report attributes this growth to several key factors. Firstly, the cost of renewable energy technologies like solar panels and wind turbines has plummeted in recent years, making them increasingly competitive with traditional fossil fuels. Secondly, advancements in battery storage technology are facilitating the integration of variable renewable sources like solar and wind into the grid, addressing concerns about reliability. Thirdly, a growing number of countries are implementing ambitious renewable energy targets and policies, driven by environmental concerns and the desire for energy security.

The rise of renewables is not uniform across the globe. Europe leads the pack, with the European Union generating a staggering 44% of its electricity from renewable sources in 2023. Countries like Denmark, Germany, and Spain are at the forefront of this clean energy revolution. Developing nations are also starting to embrace renewables, driven by factors like falling technology costs and the need for affordable electricity access.

However, challenges remain. Fossil fuels still dominate the global energy mix, accounting for roughly two-thirds of electricity generation. Integrating a higher proportion of variable renewables into the grid necessitates robust storage solutions and smart grid technologies. Additionally, the transition away from fossil fuels needs to be managed carefully to ensure a just and equitable outcome for workers in the coal, oil, and gas sectors.

Despite these challenges, the report by Ember paints an optimistic picture. The rapid growth of renewables demonstrates their increasing viability and underscores the global commitment to a cleaner energy future, and in the United States, for example, renewables are projected to reach one-fourth of U.S. electricity generation, reinforcing this trajectory. The report also highlights the economic benefits of renewables, with new jobs created in the clean energy sector and reduced reliance on volatile fossil fuel prices.

Looking ahead, continued technological advancements, supportive government policies, and increased investment in renewable energy infrastructure are all crucial for further growth, with scenarios such as BNEF's 2050 outlook suggesting wind and solar could provide half of electricity, underscoring the importance of sustained effort. Furthermore, international cooperation is essential to ensure a smooth and equitable global energy transition. Developed nations can play a vital role by sharing technology and expertise with developing countries.

The 30% milestone is a significant step forward, but it's just the beginning. As the world strives to combat climate change and ensure energy security for future generations, renewables are poised to play a central role in powering a sustainable future, with wind and solar surpassing coal in the U.S. offering a clear signal of the shift. The report by Ember serves as a powerful reminder that a clean energy future is not just a dream, but a rapidly unfolding reality.

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.

Egypt, Eni ink MoU on hydrogen production projects

Egypt-ENI Hydrogen MoU outlines joint feasibility studies for green and blue hydrogen using renewable energy, carbon capture, and CO2 storage, targeting domestic demand, exports, and net-zero goals within Egypt's energy transition.

 

Key Points

A pact to study green and blue hydrogen in Egypt, leveraging renewables, CO2 storage, and export/demand pathways.

✅ Feasibility study for green and blue hydrogen projects

✅ Uses renewables, SMR, carbon capture, and CO2 storage

✅ Targets local demand, exports, and net-zero alignment

 

The Egyptian Electricity Holding Company (EEHC) and the Egyptian Natural Gas Holding Company (EGAS) signed a memorandum of understanding (MoU) with the Italian energy giant Eni to assess the technical and commercial feasibility of green and blue hydrogen production projects in Egypt, which many see as central to power companies' future strategies worldwide today.

Under the MoU, a study will be conducted to assess joint projects for the production of green hydrogen using electricity generated from renewable energy and supported by regional electricity interconnections where relevant, and blue hydrogen using the storage of CO2 in depleted natural gas fields, according to a statement by the Ministry of Petroleum on Thursday.

The study will also estimate the potential local market consumption of hydrogen and export opportunities, taking cues from Ontario's hydrogen economy proposal to align electricity rates for growth.

This agreement is part of Eni's objective to achieve zero net emissions by 2050 and Egypt's strategy towards diversifying the energy mix and developing hydrogen projects in collaboration with major international companies, taking note of Italy's green hydrogen initiatives in Sicily as a comparable effort.

It signed the deal with Egyptian Natural Gas Holding (EGAS) and Egyptian Electricity Holding Co. (EEHC).

The companies will carry out a joint study on producing renewable energy powered green hydrogen, informed by electrolyzer investments in similar projects, where applicable. They will also work on blue hydrogen. This involves reforming natural gas and capturing the resulting CO2, in this instance in depleted natural gas fields.

The study will also consider domestic hydrogen use and export options, including funding models like the Hydrogen Innovation Fund now in Ontario.

Eni said the MoU was in line with its plans to eliminate net emissions and emissions cancel emission intensity by 2050. The company noted the agreement was in line with Egypt’s plan for the energy transition, in which it pursues hydrogen plans with major international companies, alongside broader clean-tech collaboration such as Tesla cooperation discussions in Dubai, to accelerate progress.

U.S. Speeds Up Permitting for Geothermal Energy

Geothermal Emergency Permitting accelerates BLM approvals on public lands via categorical exclusions for exploratory drilling and geophysical surveys, boosting domestic energy security, cutting timelines by up to a year, and streamlining low-impact reviews.

 

Key Points

A policy fast-tracking geothermal exploration on public lands, using BLM categorical exclusions to cut review delays.

✅ Categorical exclusions speed exploratory drilling approvals

✅ Cuts permitting timelines by up to one year

✅ Focused on public lands to enhance energy security

 

In a significant policy shift, the U.S. Department of the Interior has introduced emergency permitting procedures aimed at expediting the development of geothermal energy projects. This initiative, announced on May 30, 2025, is part of a broader strategy to enhance domestic energy production, seen in proposals to replace Obama's power plant overhaul and reduce reliance on foreign energy sources.

Background and Rationale

The decision to fast-track geothermal energy projects comes in the wake of President Donald Trump's declaration of a national energy emergency, which faces a legal challenge from Washington's attorney general, on January 20, 2025. This declaration cited high energy costs and an unreliable energy grid as threats to national security and economic prosperity. While the emergency order includes traditional energy resources such as oil, gas, coal, and uranium and nuclear energy resources, it notably excludes renewable sources like solar, wind, and hydrogen from its scope.

Geothermal energy, which harnesses heat from beneath the Earth's surface to generate electricity, is considered a reliable and low-emission energy source. However, its development has been hindered by lengthy permitting processes and environmental reviews, with recent NEPA rule changes influencing timelines. The new emergency permitting procedures aim to address these challenges by streamlining the approval process for geothermal projects.

Key Features of the Emergency Permitting Procedures

Under the new guidelines, the Bureau of Land Management (BLM) has adopted categorical exclusions to expedite the review and approval of geothermal energy exploration on public lands. These exclusions allow for faster permitting of low-impact activities, such as drilling exploratory wells and conducting geophysical surveys, without the need for extensive environmental assessments.

Additionally, the BLM has proposed a new categorical exclusion that would apply to operations related to the search for indirect evidence of geothermal resources. This proposal is currently open for public comment and, if finalized, would further accelerate the discovery of new geothermal resources on public lands.

Expected Impact on Geothermal Energy Development

The implementation of these emergency permitting procedures is expected to significantly reduce the time and cost associated with developing geothermal energy projects. According to the Department of the Interior, the new measures could cut permitting timelines by up to a year for certain types of geothermal exploration activities.

This acceleration in project development is particularly important given the untapped geothermal potential in regions like Nevada, which is home to some of the largest undeveloped geothermal resources in the country.

Industry and Environmental Reactions

The geothermal industry has largely welcomed the new permitting procedures, viewing them as a necessary step to unlock the full potential of geothermal energy. Industry advocates argue that reducing permitting delays will facilitate the deployment of geothermal projects, contributing to a more reliable and sustainable energy grid amid debates over electricity pricing changes that affect market signals.

However, the exclusion of solar and wind energy projects from the emergency permitting procedures has drawn criticism from some environmental groups. Critics argue that a comprehensive approach to energy development should include all renewable sources, not just geothermal, to effectively address climate change, as reflected in new EPA pollution limits for coal and gas power plants, and promote energy sustainability.

The U.S. government's move to implement emergency permitting procedures for geothermal energy development marks a significant step toward enhancing domestic energy production and reducing reliance on foreign energy sources. By streamlining the approval process for geothermal projects, the administration aims to accelerate the deployment of this reliable and low-emission energy source. While the exclusion of other renewable energy sources from the emergency procedures has sparked debate, especially after states like California halted an energy rebate program during a federal freeze, the focus on geothermal energy underscores its potential role in the nation's energy future.

Explainer: Why nuclear-powered France faces power outage risks

France Nuclear Power Outages threaten the grid as EDF reactors undergo stress corrosion inspections, maintenance delays, and staff shortages, driving electricity imports, peak-demand curtailment plans, and potential rolling blackouts during a cold snap across Europe.

 

Key Points

EDF maintenance and stress corrosion cut reactor output, forcing imports and blackouts as cold weather lifts demand.

✅ EDF inspects stress corrosion cracks in reactor piping

✅ Maintenance backlogs and skilled labor shortages slow repairs

✅ Government plans demand cuts, imports, and rolling blackouts

 

France is bracing for possible power outages in the coming days as falling temperatures push up demand while state-controlled nuclear group EDF struggles to bring more production on line.


WHY CAN'T FRANCE MEET DEMAND?
France is one of the most nuclear-powered countries in the world, with a significant role of nuclear power in its energy mix, typically producing over 70% of its electricity with its fleet of 56 reactors and providing about 15% of Europe's total power through exports.

However, EDF (EDF.PA) has had to take a record number of its ageing reactors offline for maintenance this year just as Europe is struggling to cope with cuts in Russian natural gas supplies used for generating electricity, with electricity prices surging across the continent this year.

That has left France's nuclear output at a 30-year low, and mirrors how Europe is losing nuclear power more broadly, forcing France to import electricity and prepare plans for possible blackouts as a cold snap fuels demand for heating.


WHAT ARE EDF'S MAINTENANCE PROBLEMS?
While EDF normally has a number of its reactors offline for maintenance, it has had far more than usual this year due to what is known as stress corrosion on pipes in some reactors, and during heatwaves river temperature limits have constrained output further.

At the request of France's nuclear safety watchdog, EDF is in the process of inspecting and making repairs across its fleet since detecting cracks in the welding connecting pipes in one reactor at the end of last year.

Years of under-investment in the nuclear sector mean that there is precious little spare capacity to meet demand while reactors are offline for maintenance, and environmental constraints such as limits on energy output during high river temperatures reduce flexibility.

France also lacks specialised welders and other workers in sufficient numbers to be able to make repairs fast enough to get reactors back online.

 

WHAT IS BEING DONE?
In the very short term, after a summer when power markets hit records as plants buckled in heat, there is little that can be done to get more reactors online faster, leaving the government to plan for voluntary cuts at peak demand periods and limited forced blackouts.

In the very short term, there is little that can be done to get more reactors online faster, leaving the government to plan for voluntary cuts at peak demand periods and limited forced blackouts.

Meanwhile, EDF and others in the French nuclear industry are on a recruitment drive for the next generation of welders, pipe-fitters and boiler makers, going so far as to set up a new school to train them.

President Emmanuel Macron wants a new push in nuclear energy, even as a nuclear power dispute with Germany persists, and has committed to building six new reactors at a cost his government estimates at nearly 52 billion euros ($55 billion).

As a first step, the government is in the process of buying out EDF's minority shareholders and fully nationalising the debt-laden group, which it says is necessary to make the long-term investments in new reactors.

Failed PG&E power line blamed for Drum fire off Hwy 246 last June

PG&E Drum Fire Cause identified as a power line failure in Santa Barbara County, with arcing electricity igniting vegetation near Buellton on Drum Canyon Road; 696 acres burned as investigators and CPUC review PG&E safety.

 

Key Points

A failed PG&E power line sparked the 696-acre Drum Fire near Buellton; the utility is conducting its own probe.

✅ Power line failed between poles, arcing ignited vegetation.

✅ 696 acres burned; no structures damaged or injuries.

✅ PG&E filed CPUC incident report; ongoing investigation.

 

A downed Pacific Gas and Electric Co. power line was the cause of the Drum fire that broke out June 14 on Drum Canyon Road northwest of Buellton, a reminder that a transformer explosion can also spark multiple fires, the Santa Barbara County Fire Department announced Thursday.

The fire broke out about 12:50 p.m. north of Highway 246 and burned about 696 acres of wildland before firefighters brought it under control, although no structures were damaged or mass outages like the Los Angeles power outage occurred, according to an incident summary.

A team of investigators pinpointed the official cause as a power line that failed between two utility poles and fell to the ground, and as downed line safety tips emphasize, arcing electricity ignited the surrounding vegetation, said County Fire Department spokesman Capt. Daniel Bertucelli.

In response, a PG&E spokesman said the utility is conducting its own investigation and does not have access to whatever data investigators used, and, as the ATCO regulatory penalty illustrates, such matters can draw significant oversight, but he noted the company filed an electric incident report on the wire with the California Public Utilities Commission on June 14.

"We are grateful to the first responders who fought the 2020 Drum fire in Santa Barbara County and helped make sure that there were no injuries or fatalities, outcomes not always seen in copper theft incidents, and no reports of structures damaged or burned," PG&E spokesman Mark Mesesan said.

"While we are continuing to conduct our own investigation into the events that led to the Drum fire, and as the Site C watchdog inquiry shows, oversight bodies can seek more transparency, PG&E does not have access to the Santa Barbara County Fire Department's report."

He said PG&E remains focused on reducing wildfire risk across its service area while limiting the scope and duration of public safety power shutoffs, including strategies like line-burying decisions adopted by other utilities, and that the safety of customers and communities it serves are its most important responsibility.
