Hurricane Katrina helped University of Texas professor, Alexis Kwasinski, formulate a new plan for the U.S. telecom system: a de-centralized power architecture that would have kept the lights and phones on in New Orleans.

Kwasinski maintains that a microgrid-based power plant with its own local power sources and independent control would be more dependable, efficient, and cost effective than traditional telecom power systems.

Microgrids would also be a quick and inexpensive way to include renewable energy sources for both existing and developing systems.

"There has been surprisingly little research on disaster damage and restoration of telecommunications systems," says Kwasinski. "My survey of the Gulf coast after Katrina showed how devastating a single downed line or incapacitated substation can be. The answer is diverse power input. You integrate different types of local power sources with diverse energy delivery infrastructures through multiple-input converter modules."

Since the communications industry power standard is direct current (DC) local networks, Kwasinski is exploring DC generation systems using a microgrid-based telecom power plant with a modular distributed architecture. Energy would come from a mixture of renewable energy sources, microturbines, fuel cells, and interconnection to the existing utility grid. Converters in secondary distribution frames would isolate short circuit currents. Since the utility grid is a secondary source, the microgrid would be protected against the grid's surges and failures.

The savings would be generous. Microgrids could "sell" excess power to the utility grid.

Costs decrease because of reduced energy storage, less down time, equipment operating at maximum efficiency, lower hardware expense, and optimal power input control based on energy costs.

"I think the most exciting aspect of the research is how flexible this approach is," says Kwasinski. "It works for developing countries who can add components to the system as they can afford it. Existing systems can easily be retrofitted with a microgrid system operating as a secondary distribution method. Small devices like solar panels and windmills can be added ad hoc, making for a painless transition to renewable energy at a competitive cost."

Wind Power Surges in U.S. Electricity Mix

U.S. Wind Power 2025 drives record capacity additions, with FERC data showing robust renewable energy growth, IRA incentives, onshore and offshore projects, utility-scale generation, grid integration, and manufacturing investment boosting clean electricity across key states.

 

Key Points

Overview of record wind additions, IRA incentives, and grid expansion defining the U.S. clean electricity mix in 2025.

✅ FERC: 30.1% of new U.S. capacity in Jan 2025 from wind

✅ Major projects: Cedar Springs IV, Boswell, Prosperity, Golden Hills

✅ IRA incentives drive onshore, offshore builds and manufacturing

 

In early 2025, wind power has significantly strengthened its position in the United States' electricity generation portfolio. According to data from the Federal Energy Regulatory Commission (FERC), wind energy accounted for 30.1% of the new electricity capacity added in January 2025, and as the most-used renewable source in the U.S., it also surpassed the previous record set in 2024. This growth is attributed to substantial projects such as the 390.4 MW Cedar Springs Wind IV and the 330.0 MW Boswell Wind Farm in Wyoming, along with the 300.0 MW Prosperity Wind Farm in Illinois and the 201.0 MW Golden Hills Wind Farm Expansion in Oregon. 

The expansion of wind energy capacity is part of a broader trend where solar and wind together accounted for over 98% of the new electricity generation capacity added in the U.S. in January 2025. This surge is further supported by the federal government's Inflation Reduction Act (IRA) and broader policy support for renewables, which has bolstered incentives for renewable energy projects, leading to increased investments and the establishment of new manufacturing facilities. 

By April 2025, clean electricity sources, including wind and solar, were projected to surpass 51% of total utility-scale electricity generation in the U.S., building on a 25.5% renewable share seen in recent data, marking a significant milestone in the nation's energy transition. This achievement is attributed to a combination of factors: a seasonal drop in electricity demand during the spring shoulder season, increased wind speeds in key areas like Texas, and higher solar production due to longer daylight hours and expanded capacity in states such as California, Arizona, and Nevada, supported by record installations across the solar and storage industry. 

Despite a 7% decline in wind power production in early April compared to the same period in 2024—primarily due to weaker wind speeds in regions like Texas—the overall contribution of wind energy remained robust, supported by an 82% clean-energy pipeline that includes wind, solar, and batteries. This resilience underscores the growing reliability of wind power as a cornerstone of the U.S. electricity mix. 

Looking ahead, the U.S. Department of Energy projects that wind energy capacity will continue to grow, with expectations of adding between 7.3 GW and 9.9 GW in 2024, and potentially increasing to 14.5 GW to 24.8 GW by 2028. This growth is anticipated to be driven by both onshore and offshore wind projects, with onshore wind representing the majority of new additions, continuing a trajectory since surpassing hydro capacity in 2016 in the U.S.

Early 2025 has witnessed a notable increase in wind power's share of the U.S. electricity generation mix. This trend reflects the nation's ongoing commitment to expanding renewable energy sources, especially after renewables surpassed coal in 2022, supported by favorable policies and technological advancements. As the U.S. continues to invest in and develop wind energy infrastructure, the role of wind power in achieving a cleaner and more sustainable energy future becomes increasingly pivotal.

Global push needed to ensure "clean, affordable and sustainable electricity" for all

SDG7 Energy Progress Report assesses global energy access, renewables, clean cooking, and efficiency, citing COVID-19 setbacks, financing needs, and UN-led action by IEA, IRENA, World Bank, and WHO to advance sustainable, reliable, affordable power.

 

Key Points

A joint study by IEA, IRENA, UN, World Bank, and WHO tracking energy access, renewables, efficiency, and financing gaps.

✅ Tracks disparities in electricity access amid COVID-19 setbacks

✅ Emphasizes renewables, clean cooking, and efficiency targets

✅ Calls for scaled public finance to unlock private investment

 

The seventh Sustainable Development Goal (SDG), SDG7, aims to ensure access to affordable, reliable, sustainable and modern energy for all.  

However, those nations which remain most off the grid, are set to enter 2030 without meeting this goal unless efforts are significantly scaled up, warns the new study entitled Tracking SDG 7: The Energy Progress Report, published by the International Energy Agency (IAE), International Renewable Energy Agency (IRENA), UN Department of Economic and Social Affairs (UN DESA), World Bank, and World Health Organization (WHO). 

“Moving towards scaling up clean and sustainable energy is key to protect human health and to promote healthier populations, particularly in remote and rural areas”, said Maria Neira, WHO Director of the Department of Environment, Climate Change and Health.  

COVID setbacks 
The report outlines significant but unequal progress on SDG7, noting that while more than one billion people globally gained access to electricity over the last decade, COVID’s financial impact so far, has made basic electricity services unaffordable for 30 million others, mostly in Africa, intensifying calls for funding for access to electricity across the region.  

“The Tracking SDG7 report shows that 90 per cent of the global population now has access to electricity, but disparities exacerbated by the pandemic, if left unaddressed, may keep the sustainable energy goal out of reach, jeopardizing other SDGs and the Paris Agreement’s objectives”, said Mari Pangestu, Managing Director of Development Policy and Partnerships at the World Bank. 

While the report also finds that the COVID-19 pandemic has reversed some progress, Stefan Schweinfest, DESA’s Director of the Statistics Division, pointed out that this has presented “opportunities to integrate SDG 7-related policies in recovery packages and thus to scale up sustainable development”. 

Modernizing renewables 
The publication examines ways to bridge gaps to reach SDG7, chief among them the scaling up of renewables, as outlined in the IRENA renewables report, which have proven more resilient than other parts of the energy sector during the COVID-19 crisis. 

While sub-Saharan Africa, facing a major electricity challenge, has the largest share of renewable sources in its energy supply, they are far from “clean” – 85 per cent use biomass, such as burning wood, crops and manure. 

“On a global path to achieving net-zero emissions by 2050, we can reach key sustainable energy targets by 2030, aligning with renewable ambition in NDCs as we expand renewables in all sectors and increase energy efficiency”, said IAE Executive Director, Fatih Birol.  

And although the private sector continues to source clean energy investments, the public sector remains a major financing source, central in leveraging private capital, particularly in developing countries, including efforts to put Africa on a path to universal electricity access, and in a post-COVID context. 

Amid the COVID-19 pandemic, which has dramatically increased investors’ risk perception and shifting priorities in developing countries, international financial flows in public investment terms, are more critical than ever to underpin a green energy recovery that can leverage the investment levels needed to reach SDG 7, according to the report.   

“Greater efforts to mobilize and scale up investment are essential to ensure that energy access progress continues in developing economies”, he added.  

Scaling up clean and sustainable energy is key to protect human health -- WHO's Maria Neira

Other key targets 
The report highlighted other crucial actions needed on clean cooking, energy efficiency and international financial flows. 

A healthy and green recovery from COVID-19 includes the importance of ensuring a quick transition to clean and sustainable energy”, said Dr. Neira. 

Feeding into autumn summit 
This seventh edition of the report formerly known as the Global Tracking Framework comes at a crucial time as Governments and others are gearing up for the UN High-level Dialogue on Energy in September 2021 aimed to examine what is needed to achieve SDG7 by 2030, including discussions on fossil fuel phase-out strategies, and mobilize voluntary commitments and actions through Energy Compacts.  

The report will inform the summit-level meeting on the current progress towards SDG 7, “four decades after the last high-level event dedicated to energy under the auspices of UN General Assembly”, said Mr. Schweinfest.

Big prizes awarded to European electricity prediction specialists

Electricity Grid Flow Prediction leverages big data, machine learning, and weather analytics to forecast power flows across smart grids, enhancing reliability, reducing blackouts and curtailment, and optimizing renewable integration under EU Horizon 2020 innovation.

 

Key Points

Short-term forecasting of power flows using big data, weather inputs, and machine learning to stabilize smart grids.

✅ Uses big data, weather, and ML for 6-hour forecasts

✅ Improves reliability, cuts blackouts and energy waste

✅ Supports smart grids, renewables, and grid balancing

 

Three European prediction specialists have won prizes worth €2 million for developing the most accurate predictions of electricity flow through a grid

The three winners of the Big Data Technologies Horizon Prize received their awards at a ceremony on 12th November in Austria.

The first prize of €1.2 million went to Professor José Vilar from Spain, while Belgians Sofie Verrewaere and Yann-Aël Le Borgne came in joint second place and won €400,000 each.

The challenge was open to individuals groups and organisations from countries taking part in the EU’s research and innovation programme, Horizon 2020.

Carlos Moedas, Commissioner for Research, Science and Innovation, said: “Energy is one of the crucial sectors that are being transformed by the digital grid worldwide.

“This Prize is a good example of how we support a positive transformation through the EU’s research and innovation programme, Horizon 2020.

“For the future, we have designed our next programme, Horizon Europe, to put even more emphasis on the merger of the physical and digital worlds across sectors such as energy, transport and health.”

The challenge for the applicants was to create AI-driven software that could predict the likely flow of electricity through a grid taking into account a number of factors including the weather and the generation source (i.e. wind turbines, solar cells, etc).

Using a large quantity of data from electricity grids, EU smart meters, combined with additional data such as weather conditions, applicants had to develop software that could predict the flow of energy through the grid over a six-hour period.

Commissioner for Digital Economy and Society Mariya Gabriel said: “The wide range of possible applications of these winning submissions could bring tangible benefits to all European citizens, including efforts to tackle climate change with machine learning across sectors.”

The decision to focus on energy grids for this particular prize was driven by a clear market need, including expanding HVDC technology capabilities.

Today’s energy is produced at millions of interconnected and dispersed unpredictable sites such as wind turbines, solar cells, etc., so it is harder to ensure that electricity supply matches the demand at all times.

This complexity means that huge amounts of data are produced at the energy generation sites, in the grid and at the place where the energy is consumed.

Being able to make accurate, short-term predictions about power grid traffic is therefore vital to reduce the risks of blackouts or, by enabling utilities to use AI for energy savings, limit waste of energy.

Reliable predictions can also be used in fields such as biology and healthcare. The predictions can help to diagnose and cure diseases as well as to allocate resources where they are most needed.

Ultimately, the winning ideas are set to be picked up by the energy sector in the hopes of creating smarter electricity infrastructure, more economic and more reliable power grids.

Nearly 600 Hong Kong families still without electricity after power supply cut by Typhoon Mangkhut

Hong Kong Typhoon Mangkhut Power Outages strain households with blackouts, electricity disruption, and humid heat, impacting Tin Ping Estate in Sheung Shui and outlying islands; contractor-led restoration faces fines for delays and infrastructure repairs.

 

Key Points

They are blackout events after Typhoon Mangkhut, bringing heat stress, food spoilage, and delayed power restoration.

✅ 16 floors in Tin Ping Estate lost power after meter room blast.

✅ Contractor faces HK$100,000 daily fines for late restoration.

✅ Kat O and Ap Chau families remain off-grid in humid heat.

 

Nearly 600 Hong Kong families are still sweltering under the summer heat and facing dark nights without electricity after Typhoon Mangkhut cut off power supply to areas, echoing mass power outages seen elsewhere.

At Sheung Shui’s Tin Ping Estate in the New Territories, 384 families were still without power, a situation similar to the LA-area blackout that left many without service. They were told on Tuesday that a contractor would rectify the situation by Friday, or be fined HK$100,000 for each day of delay.

In remote areas such as outlying islets Kat O and Ap Chau, there were some 200 families still without electricity, similar to Tennessee storm outages affecting rural communities.

The power outage at Tin Ping Estate affected 16 floors – from the 11th to 26th – in Tin Cheung House after a blast from the meter room on the 15th floor was heard at about 5pm on Sunday, and authorities urged residents to follow storm electrical safety tips during repairs.

“I was sitting on the sofa when I heard a loud bang,” said Lee Sau-king, 61, whose flat was next to the meter room. “I was so scared that my hands kept trembling.”

While the block’s common areas and lifts were not affected, flats on the 16 floors encountered blackouts.

As her fridge was out of power, Lee had to throw away all the food she had stocked up for the typhoon. With the freezer not functioning, her stored dried seafood became soaked and she had to dry them outside the window when the storm passed.

Daily maximum temperatures rose back to 30 degrees Celsius after the typhoon, and nights became unbearably humid, as utilities worldwide pursue utility climate adaptation to maintain reliability. “It’s too hot here. I can’t sleep at all,” Lee said.

Doug Ford ‘proud’ of decision to tear up hundreds of green energy contracts

Ontario Renewable Energy Cancellations highlight Doug Ford's move to scrap wind turbine contracts, citing electricity rate relief and taxpayer savings, while critics, the NDP, and industry warn of job losses, termination fees, and auditor scrutiny.

 

Key Points

Ontario's termination of renewable contracts, defended as cost and rate relief, faces disputes over savings and jobs.

✅ PCs cite electricity rate relief and taxpayer savings.

✅ Critics warn of job losses and termination fees.

✅ Auditor inquiry sought into contract cancellation costs.

 

Ontario Premier Doug Ford, whose new stance on wind power has drawn attention, said Thursday he is “proud” of his decision to tear up hundreds of renewable energy deals, a move that his government acknowledges could cost taxpayers more than $230 million.

Ford dismissed criticism that his Progressive Conservatives are wasting public money, telling a news conference that the cancellation of 750 contracts signed by the previous Liberal government will save cash, even as Ontario moves to reintroduce renewable energy projects in the coming years.

“I’m so proud of that,” Ford said of his decision. “I’m proud that we actually saved the taxpayers $790 million when we cancelled those terrible, terrible, terrible wind turbines that really for the last 15 years have destroyed our energy file.”

Later Thursday, Ford went further in defending the cancelled contracts, saying “if we had the chance to get rid of all the wind mills we would,” though a court ruling near Cornwall challenged such cancellations.

The NDP first reported the cost of the cancellations Tuesday, saying the $231 million figure was listed as “other transactions”, buried in government documents detailing spending in the 2018-2019 fiscal year.

The Progressive Conservatives have said the final cost of the cancellations, which include the decommissioning of a wind farm already under construction in Prince Edward County, Ont., has yet to be established, amid warnings about wind project cancellation costs from developers.

The government has said it tore up the deals because the province didn’t need the power and it was driving up electricity rates, and the decision will save millions over the life of the contracts. Industry officials have disputed those savings, saying the cancellations will just mean job losses for small business, and ignore wind power’s growing competitiveness in electricity markets.

NDP Leader Andrea Horwath has asked Ontario’s auditor general to investigate the contracts and their termination fees, amid debates over Ontario’s electricity future among leadership contenders. She called Ford’s remarks on Thursday “ridiculous.”

“Every jurisdiction around the world is trying to figure out how to bring more renewables onto their electricity grids,” she said. “This government is taking us backwards and costing us at the very least $231 million in tearing these energy contracts.”

At the federal level, a recent green electricity contract with an Edmonton company underscores that shift.

Germany is first major economy to phase out coal and nuclear

Germany Coal Phase-Out 2038 advances the energy transition, curbing lignite emissions while scaling renewable energy, carbon pricing, and hydrogen storage amid a nuclear phase-out and regional just-transition funding for miners and communities.

 

Key Points

Germany's plan to end coal by 2038, fund regional transition, and scale renewable energy while exiting nuclear.

✅ Closes last coal plant by 2038; reviews may accelerate.

✅ 40b euros aid for lignite regions and workforce.

✅ Emphasizes renewables, hydrogen, carbon pricing reforms.

 

German lawmakers have finalized the country's long-awaited phase-out of coal as an energy source, backing a plan that environmental groups say isn't ambitious enough and free marketeers criticize as a waste of taxpayers' money.

Bills approved by both houses of parliament Friday envision shutting down the last coal-fired power plant by 2038 and spending some 40 billion euros ($45 billion) to help affected regions cope with the transition, which has been complicated by grid expansion woes in recent years.

The plan is part of Germany's `energy transition' - an effort to wean Europe's biggest economy off planet-warming fossil fuels and generate all of the country's considerable energy needs from renewable sources. Achieving that goal is made harder than in comparable countries such as France and Britain because of Germany's existing commitment to also phase out nuclear power entirely by the end of 2022.

"The days of coal are numbered in Germany," Environment Minister Svenja Schulze said. "Germany is the first industrialized country that leaves behind both nuclear energy and coal."

Greenpeace and other environmental groups have staged vocal protests against the plan, including by dropping a banner down the front of the Reichstag building Friday. They argue that the government's road map won't reduce Germany's greenhouse gas emissions fast enough to meet the targets set out in the Paris climate accord.

"Germany, the country that burns the greatest amount of lignite coal worldwide, will burden the next generation with 18 more years of carbon dioxide," Greenpeace Germany's executive director Martin Kaiser told The Associated Press.

Kaiser, who was part of a government-appointed expert commission, accused Chancellor Angela Merkel of making a "historic mistake," saying an end date for coal of 2030 would have sent a strong signal for European and global climate policy. Merkel has said she wants Europe to be the first continent to end its greenhouse gas emissions, by 2050, even as some in Berlin debate a possible nuclear U-turn to reach that goal faster.

Germany closed its last black coal mine in 2018, but it continues to import the fuel and extract its own reserves of lignite, a brownish coal that is abundant in the west and east of the country, and generates about a third of its electricity from coal in recent years. Officials warn that the loss of mining jobs could hurt those economically fragile regions, though efforts are already under way to turn the vast lignite mines into nature reserves and lakeside resorts.

Schulze, the environment minister, said there would be regular government reviews to examine whether the end date for coal can be brought forward, even as Berlin temporarily extended nuclear operations during the energy crisis. She noted that by the end of 2022, eight of the country's most polluting coal-fired plants will have already been closed.

Environmentalists have also criticized the large sums being offered to coal companies to shut down their plants, a complaint shared by libertarians such as Germany's opposition Free Democratic Party.

Katja Suding, a leading FDP lawmaker, said the government should have opted to expand existing emissions trading systems that put a price on carbon, thereby encouraging operators to shut down unprofitable coal plants.

Katja Suding, a leading FDP lawmaker, said the government should have opted to expand existing emissions trading systems, rather than banking on a nuclear option, that put a price on carbon, thereby encouraging operators to shut down unprofitable coal plants.

"You just have to make it so expensive that it's not profitable anymore to turn coal into electricity," she said.

This week, utility companies in Spain shut down seven of the country's 15 coal-fired power plants, saying they couldn't be operated at profit without government subsidies.

But the head of Germany's main miners' union, Michael Vassiliadis, welcomed the decision, calling it a "historic milestone." He urged the government to focus next on an expansion of renewable energy generation and the use of hydrogen as a clean alternative for storing and transporting energy in the future, amid arguments that nuclear won't fix the gas crunch in the near term.
