Florine Patrick was one of 50 homeowners in the Pleasant City neighborhood of West Palm Beach treated to a Home Energy Makeover recently.

Florida Power & Light energy consultants and 60 volunteers teamed with the city to perform energy efficient upgrades for 50 low-income homes in the historic community. To complete all 50 makeovers in one day, 12 teams of four to five volunteers that included FPL energy specialists visited the homes of residents who were pre-qualified through an application process with the city to identify homes in eligible low-income neighborhoods.

The teams, sometimes with the assistance of contractors, spent a few hours in each home, installing energy efficient upgrades from weather stripping and new air-conditioning filters, to repairing holes in ducts or closets that hampered air conditioning.

FPL has previously performed such energy makeovers in Sarasota and Broward counties.

Mayor Lois Frankel marked the event by proclaiming Nov. 13 Energy Awareness Day in West Palm Beach. Frankel said "It is my hope that all of our residents will be motivated to embrace energy-efficient practices in their own homes."

Bomb Cyclone Leaves Half a Million Without Power in Western Washington

Western Washington Bomb Cyclone unleashed gale-force winds, torrential rain, and coastal flooding, causing massive power outages from Seattle to Tacoma; storm surge, downed trees, and blocked roads hindered emergency response and infrastructure repairs.

 

Key Points

A rapidly deepening storm with severe winds, rain, flooding, and major power outages across Western Washington.

✅ Rapid barometric pressure drop intensified the system

✅ Gale-force winds downed trees and power lines

✅ Coastal flooding and storm surge disrupted transport

 

A powerful "bomb cyclone" recently hit Western Washington, causing widespread destruction across the region. The intense storm left more than half a million residents without power, similar to B.C. bomb cyclone outages seen to the north, with outages affecting communities from Seattle to Olympia. This weather phenomenon, marked by a rapid drop in atmospheric pressure, unleashed severe wind gusts, heavy rain, and flooding, causing significant disruption to daily life.

The bomb cyclone, which is a rapidly intensifying storm, typically features a sharp drop in barometric pressure over a short period of time. This creates extreme weather conditions, including gale-force winds, torrential rain, and coastal flooding, as seen during California storm impacts earlier in the season. In Western Washington, the storm struck just as the region was beginning to prepare for the winter season, catching many off guard with its strength and unpredictability.

The storm's impact was immediately felt as high winds downed trees, power lines, and other infrastructure. By the time the worst of the storm had passed, utility companies had reported widespread power outages, with more than 500,000 customers losing electricity. The outages were particularly severe in areas like Seattle, Tacoma, and the surrounding communities. Crews worked tirelessly in difficult conditions to restore power, but many residents faced extended outages, underscoring US grid climate vulnerabilities that complicate recovery efforts, with some lasting for days due to the scope of the damage.

The power outages were accompanied by heavy rainfall, leading to localized flooding. Roads were inundated, making it difficult for first responders and repair crews to reach affected areas. Emergency services were stretched thin as they dealt with downed trees, blocked roads, and flooded neighborhoods. In some areas, floodwaters reached homes, forcing people to evacuate. In addition, several schools were closed, and public transportation services were temporarily halted, leaving commuters stranded and businesses unable to operate.

As the storm moved inland, its effects continued to be felt. Western Washington’s coastal regions were hammered by high waves and storm surges, further exacerbating the damage. The combination of wind and rain also led to hazardous driving conditions, prompting authorities to advise people to stay off the roads unless absolutely necessary.

While power companies worked around the clock to restore electricity, informed by grid resilience strategies that could help utilities prepare for future events, challenges persisted. Fallen trees and debris blocked access to repair sites, and the sheer number of outages made it difficult for crews to restore power quickly. Some customers were left in the dark for days, forced to rely on generators, candles, and other makeshift solutions. The storm's intensity left a trail of destruction, requiring significant resources to address the damages and rebuild critical infrastructure.

In addition to the immediate impacts on power and transportation, the bomb cyclone raised important concerns about climate change and the increasing frequency of extreme weather events. Experts note that storms like these are becoming more common, with rapid intensification leading to more severe consequences and compounding pressures such as extreme-heat electricity costs for households. As the planet warms, scientists predict that such weather systems will continue to grow in strength, posing greater challenges to cities and regions that are not always prepared for such extreme events.

In the aftermath of the storm, local governments and utility companies faced the daunting task of not only restoring services but also assessing the broader impact of the storm on communities. Many areas, especially those hit hardest by flooding and power outages, will require substantial recovery efforts. The devastation of the bomb cyclone highlighted the vulnerability of infrastructure in the face of rapidly changing weather patterns and water availability, as seen in BC Hydro drought adaptations nearby, and reinforced the need for greater resilience in the face of future storms.

The storm's impact on the Pacific Northwest is a reminder of the power of nature and the importance of preparedness. As Western Washington recovers, there is a renewed focus on strengthening infrastructure, including expanded renewable electricity to diversify supply, improving emergency response systems, and ensuring that communities are better equipped to handle the challenges posed by increasingly severe weather events. For now, residents remain hopeful that the worst is behind them and are working together to rebuild and prepare for whatever future storms may bring.

The bomb cyclone has left an indelible mark on Western Washington, but it also serves as a call to action for better preparedness, more robust infrastructure, and a greater focus on combating climate change to mitigate the impact of such extreme weather in the future.

Four Facts about Covid and U.S. Electricity Consumption

COVID-19 Impact on U.S. Electricity Consumption shows commercial and industrial demand dropped as residential use rose, with flattened peak loads, weekday-weekend convergence, Texas hourly data, and energy demand as a real-time economic indicator.

 

Key Points

It reduced commercial and industrial demand while raising residential use, shifting peaks and weekday patterns.

✅ Commercial electricity down 12%; industrial down 14% in Q2 2020

✅ Residential use up 10% amid work-from-home and lockdowns

✅ Peaks flattened; weekday-weekend loads converged in Texas

 

This is an important turning point for the United States. We have a long road ahead. But one of the reasons I’m optimistic about Biden-Harris is that we will once again have an administration that believes in science.

To embrace this return to science, I want to write today about a fascinating new working paper by Tufts economist Steve Cicala.

Professor Cicala has been studying the effect of Covid on electricity consumption since back in March, when the Wall Street Journal picked up his work documenting an 18% decrease in electricity consumption in Italy.

The new work, focused on the United States, is particularly compelling because it uses data that allows him to distinguish between residential, commercial, and industrial sectors, against a backdrop of declining U.S. electricity sales over recent years.

Without further ado, here are four facts he uncovers about Covid and U.S. electricity demand during COVID-19 and consumption.

 

Fact #1: Firms Are Using Less
U.S. commercial electricity consumption fell 12% during the second quarter of 2020. U.S. industrial electricity consumption fell 14% over the same period.

This makes sense. The second quarter was by some measures, the worst quarter for the U.S. economy in over 145 years!

Economic activity shrank. Schools closed. Offices closed. Factories closed. Restaurants closed. Malls closed. Even health care offices closed as patients delayed going to the dentist and other routine care. All this means less heating and cooling, less lighting, less refrigeration, less power for computers and other office equipment, less everything.

The decrease in the industrial sector is a little more surprising. My impression had been that the industrial sector had not fallen as far as commercial, but amid broader disruptions in coal and nuclear power that strained parts of the energy economy, the patterns for both sectors are quite similar with the decline peaking in May and then partially rebounding by July. The paper also shows that areas with higher unemployment rates experienced larger declines in both sectors.

 

Fact #2: Households Are Using More
While firms are using less, households are using more. U.S. residential electricity consumption increased 10% during the second quarter of 2020. Consumption surged during March, April, and May, a reflection of the lockdown lifestyle many adopted, and then leveled off in June and July – with much less of the rebound observed on the commercial/industrial side.

This pattern makes sense, too. In Professor Cicala’s words, “people are spending an inordinate amount of time at home”. Many of us switched over to working from home almost immediately, and haven’t looked back. This means more air conditioning, more running the dishwasher, more CNN (especially last week), more Zoom, and so on.

The paper also examines the correlates of the decline. Areas in the U.S. where more people can work from home experienced larger increases. Unemployment rates, however, are almost completely uncorrelated with the increase.

 

Fact #3: Firms are Less Peaky
The paper next turns to a novel dataset from Texas, where Texas grid reliability is under active discussion, that makes it possible to measure hourly electricity consumption by sector.

As the figure above illustrates, the biggest declines in commercial/industrial electricity consumption have occurred Monday through Friday between 9AM and 5PM.

The dashed line shows the pattern during 2019. Notice the large spikes in electricity consumption during business hours. The solid line shows the pattern during 2020. Much smaller spikes during business hours.

 

Fact #4: Everyday is Like Sunday
Finally, we have what I would like to nominate as the “Energy Figure of the Year”.

Again, start with the pattern for 2019, reflected by the dashed line. Prior to Covid, Texas households used a lot more electricity on Saturdays and Sundays.

Then along comes Covid, and turned every day into the weekend. Residential electricity consumption in Texas during business hours Monday-Friday is up 16%(!).

In the pattern for 2020, it isn’t easy to distinguish weekends from weekdays. If you feel like weekdays and weekends are becoming a big blur – you are not alone.

 

Conclusion
Researchers are increasingly thinking about electricity consumption as a real-time indicator of economic activity, even as flat electricity demand complicates utility planning and investment. This is an intriguing idea, but Professor Cicala’s new paper shows that it is important to look sector-by-sector.

While commercial and industrial consumption indeed seem to measure the strength of an economy, residential consumption has been sharply countercylical – increasing exactly when people are not at work and not at school.

These large changes in behavior are specific to the pandemic. Still, with the increased blurring of home and non-home activities we may look back on 2020 as a key turning point in how we think about these three sectors of the economy.

More broadly, Professor Cicala’s paper highlights the value of social science research. We need facts, data, and yes, science, if we are to understand the economy and craft effective policies on energy insecurity and shut-offs as well.

Cheap material converts heat to electricity

Polycrystalline Tin Selenide Thermoelectrics enable waste heat recovery with ZT 3.1, matching single crystals while cutting costs, powering greener car engines, industrial furnaces, and thermoelectric generators via p-type and emerging n-type designs.

 

Key Points

Low-cost tin selenide devices that turn waste heat into power, achieving ZT 3.1 and enabling p-type and n-type modules.

✅ Oxygen removal prevents heat-leaking tin oxide grain skins.

✅ Polycrystalline ingots match single-crystal ZT 3.1 at lower cost.

✅ N-type tin selenide in development to pair with p-type.

 

So-called thermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, providing what seems like a free lunch. But despite helping power the Mars rovers, the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermoelectrics that work just as well as the pricey kind. The work could pave the way for a new generation of greener car engines, industrial furnaces, and other energy-generating devices.

“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist at Beihang University who was not involved with the work. He notes there are still a few more steps to take before these materials can become high-performing thermoelectric generators. However, he says, “I think this will be used in the not too far future.”

Thermoelectrics are semiconductor devices placed on a hot surface, like a gas-powered car engine or on heat-generating electronics using thin-film converters to capture waste heat. That gives them a hot side and a cool side, away from the hot surface. They work by using the heat to push electrical charges from one to the other, a process of turning thermal energy into electricity that depends on the temperature gradient. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.

 Over the past 2 decades, researchers have produced thermoelectric materials with increasing ZTs, while related advances such as nighttime solar cells have broadened thermal-to-electric concepts. The record came in 2014 when Mercouri Kanatzidis, a materials scientist at Northwestern University, and his colleagues came up with a single crystal of tin selenide with a ZT of 3.1. Yet the material was difficult to make and too fragile to work with. “For practical applications, it’s a non-starter,” Kanatzidis says.

So, his team decided to make its thermoelectrics from readily available tin and selenium powders, an approach that, once processed, makes grains of polycrystalline tin selenide instead of the single crystals. The polycrystalline grains are cheap and can be heated and compressed into ingots that are 3 to 5 centimeters long, which can be made into devices. The polycrystalline ingots are also more robust, and Kanatzidis expected the boundaries between the individual grains to slow the passage of heat. But when his team tested the polycrystalline materials, the thermal conductivity shot up, dropping their ZT scores as low as 1.2.

In 2016, the Northwestern team discovered the source of the problem: an ultrathin skin of tin oxide was forming around individual grains of polycrystalline tin selenide before they were pressed into ingots. And that skin acted as an express lane for the heat to travel from grain to grain through the material. So, in their current study, Kanatzidis and his colleagues came up with a way to use heat to drive any oxygen away from the powdery precursors, leaving pristine polycrystalline tin selenide, whereas other devices can generate electricity from thin air using ambient moisture.

The result, which they report today in Nature Materials, was not only a thermal conductivity below that of single-crystal tin selenide but also a ZT of 3.1, a development that echoes nighttime renewable devices showing electricity from cold conditions. “This opens the door for new devices to be built from polycrystalline tin selenide pellets and their applications to be explored,” Kanatzidis says.

Getting through that door will still take some time. The polycrystalline tin selenide the team makes is spiked with sodium atoms, creating what is known as a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.

Zhao’s team recently reported making an n-type single-crystal tin selenide by spiking it with bromine atoms. And Kanatzidis says his team is now working on making an n-type polycrystalline version. Once n-type and p-type tin selenide devices are paired, researchers should have a clear path to making a new generation of ultra-efficient thermoelectric generators. Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial furnaces to scavenge energy from some of the 65% of fossil fuel energy that winds up as waste heat.

Russian Strikes Threaten Ukraine's Power Grid

Ukraine Power Grid Attacks intensify as missile and drone strikes hit substations and power plants, causing blackouts, humanitarian crises, strained hospitals, and emergency repairs, with winter energy shortages and civilian infrastructure damage worsening nationwide.

 

Key Points

Strikes on energy infrastructure causing blackouts, service disruption, and heightened humanitarian risk in winter.

✅ Missile and drone strikes cripple plants, substations, and lines

✅ Blackouts disrupt water, heating, hospitals, and critical services

✅ Emergency repairs, generators, and aid mitigate winter shortages

 

Ukraine's energy infrastructure remains a primary target in Russia's ongoing invasion, with a recent wave of missile strikes causing power outages in western regions and disrupting critical services across the country. These attacks have devastating humanitarian consequences, leaving millions of Ukrainians without heat, water, and electricity as winter approaches.


Systematic Targeting of Energy Infrastructure

Russia's strategy of deliberately targeting Ukraine's power grid marks a significant escalation, directly affecting the lives of civilians. Power plants, substations, and transmission lines have been hit with missiles and drones, with the latest strikes in late April causing blackouts in cities across Ukraine, including the capital, Kyiv, as the country fights to keep the lights on amid relentless bombardment.


Humanitarian Catastrophe Looms

The damage to Ukraine's electrical system hinders essential services like water supply, sewage treatment, and heating. Hospitals and other critical facilities struggle to operate without reliable power. With winter around the corner, the ongoing attacks threaten a humanitarian catastrophe even as authorities outline plans to keep the lights on this winter for vulnerable communities.


Ukrainian Resolve Remains Unbroken

Despite the devastation, Ukrainian engineers and workers race against time to repair damaged infrastructure and restore power as quickly as possible, while communities adopt new energy solutions to overcome blackouts to maintain essential services. The nation's energy workers have been hailed as heroes for their tireless efforts to keep the lights on amidst relentless attacks. Officials have urged civilians to reduce energy consumption whenever possible to alleviate strain on the fragile grid.


International Condemnation and Support

The systematic attacks on Ukraine's power grid have been widely condemned by the international community.  Western nations have accused Russia of war crimes, highlighting the deliberate targeting of civilian infrastructure. Aid organizations and countries are coordinating efforts to provide emergency power supplies, including generators and transformers, to help Ukraine mitigate the immediate crisis, even as the U.S. ended support for grid restoration in a recent policy shift.


Implications Beyond Ukraine

The humanitarian crisis unfolding in Ukraine due to power grid attacks carries implications far beyond its borders. The disruption of energy supplies could lead to further instability in neighbouring countries dependent on Ukraine's power exports, although officials say electricity reserves are sufficient to prevent scheduled outages if attacks subside. Additionally, a surge in Ukrainian refugees fleeing the deteriorating conditions could put a strain on resources within the European Union.


War Crimes Allegations

International human rights organizations are documenting evidence of Russia's deliberate attacks on Ukraine's civilian infrastructure. Human Rights Watch (HRW) has stated that Russia's targeting of power stations could violate the laws of war and amount to war crimes. This documentation will be crucial for holding Russia accountable for its actions in the future.


Uncertain Future for Ukraine's Power Supply

The long-term consequences of Russia's sustained attacks on Ukraine's power grid remain uncertain. While Ukrainian workers demonstrate incredible resilience, the sheer scale of repeated damage may eventually overwhelm their ability to keep pace with repairs, and, as winter looms over the battlefront, electricity is civilization for frontline communities. Rebuilding destroyed infrastructure could take years and cost billions, a daunting task for a nation already ravaged by war.

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.

Japan to host one of world's largest biomass power plants

eRex Biomass Power Plant will deliver 300 MW in Japan, offering stable baseload renewable energy, coal-cost parity, and feed-in tariff independence through economies of scale, efficient fuel procurement, and utility-scale operations supporting RE100 demand.

 

Key Points

A 300 MW Japan biomass project targeting coal-cost parity and FIT-free, stable baseload renewable power.

✅ 300 MW capacity; enough for about 700,000 households

✅ Aims to skip feed-in tariff via economies of scale

✅ Targets coal-cost parity with stable, dispatchable output

 

Power supplier eRex will build its largest biomass power plant to date in Japan, hoping the facility's scale will provide healthy margins, a strategy increasingly seen among renewable developers pursuing diverse energy sources, and a means of skipping the government's feed-in tariff program.

The Tokyo-based electric company is in the process of selecting a location, most likely in eastern Japan. It aims to open the plant around 2024 or 2025 following a feasibility study. The facility will cost an estimated 90 billion yen ($812 million) or so, and have an output of 300 megawatts -- enough to supply about 700,000 households. ERex may work with a regional utility or other partner

The biggest biomass power plant operating in Japan currently has an output of 100 MW. With roughly triple that output, the new facility will rank among the world's largest, reflecting momentum toward 100% renewable energy globally that is shaping investment decisions.

Nearly all biomass power facilities in Japan sell their output through the government-mediated feed-in tariff program, which requires utilities to buy renewable energy at a fixed price. For large biomass plants that burn wood or agricultural waste, the rate is set at 21 yen per kilowatt-hour. But the program costs the Japanese public more than 2 trillion yen a year, and is said to hamper price competition.

ERex aims to forgo the feed-in tariff with its new plant by reaping economies of scale in operation and fuel procurement. The goal is to make the undertaking as economical as coal energy, which costs around 12 yen per kilowatt-hour, even as solar's rise in the U.S. underscores evolving benchmarks for competitive renewables.

Much of the renewable energy available in Japan is solar power, which fluctuates widely according to weather conditions, though power prediction accuracy has improved at Japanese PV projects. Biomass plants, which use such materials as wood chips and palm kernel shells as fuel, offer a more stable alternative.

Demand for reliable sources of renewable energy is on the rise in the business world, as shown by the RE100 initiative, in which 100 of the world's biggest companies, such as Olympus, have announced their commitment to get 100% of their power from renewable sources. ERex's new facility may spur competition.
