Compact fluorescent light bulbs, with their cool, blue glow, will replace their warmer and less energy-efficient incandescent counterparts in five years, under a new federal plan.

It has many cheering, but at the same time concerned that important details — such as the safe disposal of a toxic component of the bulbs — were glossed over.

"Along with a general policy to increase the use of compact fluorescent (light bulbs), which is a reasonably happy idea for the environment, it's also necessary to think about ways of promoting the capture and recycling of those," said Ron Pushchak, a professor with Ryerson University's School of Occupational Health and Safety.

The problem lies with the mercury contained in the fluorescent bulbs. There are only four or five milligrams in a compact bulb, said Pushchak, but it's still a neurotoxin and a hazardous material.

Pushchak, who studies waste disposal and environmental impacts, said more often than not, light bulbs are broken when they're tossed out with the trash.

When that happens with a compact fluorescent bulb, the mercury vaporizes, travels in a general northern direction with the atmosphere and is deposited. It then is absorbed into plant and animal systems, as well as the soil.

Health Canada issued new recommendations for fish consumption, due to rising levels of mercury that has made its way into the food chain.

What's needed, said Pushchak, is a curbside collection system for all household hazardous waste.

"Fortunately we have some time — but not much," he said.

Attendees of the Green Living show in Toronto said, in the meantime, more information is needed. Many people there said they already use compact fluorescent bulbs to light their homes, but are unsure of how to properly dispose of them.

Jon Hagan has already thrown out a bulb that blew with a burst of white light after just two months of use. He said he would like more information and even suggests a fee be factored into the cost of the already pricey light bulbs in order to fund a disposal or recycling system.

"The claim is that there's not very much (mercury), but there are a lot of light bulbs out there," he said.

Home Depot Canada, the largest retailer of lights in the country, has said the company is working, together with Phillips Lighting, on a plan to safely recycle the fluorescents.

Beth Ross, a librarian from Goderich, Ont., said she has been using the bulbs for several years, but hasn't had to replace any.

When she does, she said she's not sure how she will go about disposing of them.

For now, her concern is that the light bulbs don't fit everywhere. "Not all of my light fixtures are suitable for them, but I expect industry will come out with a design to meet all our needs," she said.

Stacey and Shinya Kumazawa also wish the light bulbs were more versatile. They too have the bulbs in their home — everywhere they fit, that is.

"I think they're great. We try and use them as much as we can," said Stacey Kumazawa.

But Shinya Kumazawa isn't crazy about the colour. The compact fluorescent bulbs give off a cooler, bluer light rather than the warm tone the incandescent bulbs emit. As an artist, it's difficult for him to work with the different lighting, which he said is also weaker than regular bulbs.

The cost of the bulbs is also seen as a barrier to some. The compact fluorescent bulbs cost around $2.50 while incandescents are just 50 cents. However, consumers will save in the long run on energy bills.

Buyer's Remorse: Questions about grid modernization affordability

Grid Modernization drives utilities to integrate DER, AMI, and battery storage while balancing reliability, safety, and affordability; regulators pursue cost-benefit analyses, new rate design, and policy actions to guide investment and protect customer-owned resources.

 

Key Points

Upgrading the grid to manage DER with digital tools, while maintaining reliability, safety, and customer affordability.

✅ Cost-benefit analyses guide prudent grid investments

✅ AMI and storage deployments enable DER visibility and control

✅ Rate design reforms support customer-owned resources

 

Utilities’ pursuit of a modern grid, including the digital grid concept, to maintain the reliability and safety pillars of electricity delivery has raised a lot of questions about the third pillar — affordability.

Utilities are seeing rising penetrations of emerging technologies, highlighted in recent grid edge trends reports, like distributed solar, behind-the-meter battery storage, and electric vehicles. These new distributed energy resources (DER) do not eliminate utilities' need to keep distribution systems safe and reliable.

But the need for modern tools to manage DER imposes costs on utilities, prompting calls to invest in smarter infrastructure even as some regulators, lawmakers and policymakers are concerned those costs could drive up electricity rates.

The result is an increasing number of legislative and regulatory grid modernization actions aimed at identifying what is necessary to serve the coming power sector transformation and address climate change risks across the grid.

 

The rise of grid modernization

Grid modernization, which is supported by both conservatives and distributed energy resources advocates, got a lot of attention last year. According to the 2017 review of grid modernization policy by the North Carolina Clean Energy Technology Center (NCCETC), 288 grid modernization policy actions were proposed, pending or enacted in 39 states.

These numbers from NCCETC's first annual review of policy activity set a benchmark against which future years' activity can be measured.

The most common type of state actions, by far, were those that focused on the deployment of advanced metering infrastructure (AMI) and battery energy storage. Those are two of the 2017 trends identified in NCCETC’s 50 States of Grid Modernization report. But deployment of those technologies, while foundational to an updated grid, only begins to prepare distribution systems for the coming power sector transformation.

Bigger advances, including the newest energy system management tools, are being held back by 2017’s other policy actions requiring more deliberation and fact-finding, even as grid vulnerability report cards underscore the risks that modernization seeks to mitigate.

Utilities’ proposals to more fully prepare their grids to deliver 21st century technologies are being met with questions about completeness and cost.

Utilities are being asked to address these questions in comprehensive, public utility commission-led cost-benefit analyses and studies. This is also one of NCCETC’s top 2017 policy action trends for grid modernization. The outcome to date appears to be an increased, but still incomplete, understanding of what is needed to build a 21st century grid.

Among the top objectives of those driving the policy actions are resolving questions about private sector participation in grid modernizaton buildouts and developing new rate designs to protect and support customer-owned distributed energy resources. Actions on those topics are also on NCCETC’s list of 2017 policy trends.

Altogether, the trend list is dominated by actions that do not lead to completion of grid modernization but to more work on it.

U.S. Senate Looks to Modernize Renewable Energy on Public Land

PLREDA 2019 advances solar, wind, and geothermal on public lands, guiding DOI siting, improving transmission access, streamlining permitting, sharing revenues, and funding conservation to meet climate goals while protecting wildlife and recreation.

 

Key Points

A bipartisan bill to expand renewables on public lands fund conservation, speed permitting and advance U.S. climate aims.

✅ Targets 25 GW of public-land renewables by 2025

✅ Establishes wildlife conservation and recreation access funds

✅ Streamlines siting, transmission, and equitable revenue sharing

 

The Senate unveiled its version of a bill the House introduced in July to help the U.S. realize the extraordinary renewable energy potential of our shared public lands.

Senator Martha McSally (R-AZ) and a bipartisan coalition of western Senators introduced a Senate version of draft legislation that will help the Department of the Interior tap the renewable energy potential of our shared public lands. The western Senators represent Arizona, New Mexico, Colorado, Montana, and Idaho.

Elsewhere in the West, lawmakers have moved to modernize Oregon hydropower to streamline licensing, signaling broad regional momentum.

The Public Land Renewable Energy Development Act of 2019 (PLREDA) facilitates siting of solar, wind, and geothermal energy projects on public lands, boosts funding for conservation, and promotes ambitious renewable energy targets that will help the U.S. take action on the climate crisis.

Like the House version, the Senate bill enjoys strong bi-partisan support and industry endorsement. The Senate version makes few notable changes to the bill introduced in July by Representatives Mike Levin (D-CA) and Paul Gosar (R-AZ). It includes:

  • A commitment to enhance natural resource conservation and stewardship via the establishment of a fish and wildlife conservation fund that would support conservation and restoration work and other important stewardship activities.
  • An ambitious renewable energy production goal for the Department of the Interior to permit a total of 25 gigawatts of renewable energy on public lands by 2025—nearly double the current generating capacity of projects currently on our public lands.
  • Establishment of criteria for identifying appropriate areas for renewable energy development using the 2012 Western Solar Plan as a model. Key criteria to be considered include access to transmission lines and likelihood of avoiding or minimizing conflict with wildlife habitat, cultural resources, and other resources and values.
  • Improved public access to Federal lands for recreational uses via funds made available for preserving and improving access, including enhancing public access to places that are currently inaccessible or restricted.
  • Sharing of revenues raised from renewable energy development on public lands in an equitable manner that benefits local communities near new renewable energy projects and supports the efficient administration of permitting requirements.
  • Creating incentives for renewable energy development by giving Interior the authority to reduce rental rates and capacity fees to ensure new renewable energy development remains competitive in the marketplace.

NRDC strongly supports this legislation, and we will do our utmost to facilitate its passage into law. There is no question that in our era of runaway climate change, legislation that balances energy production with environmental conservation and stewardship of our public lands is critical.

PLREDA takes a balanced approach to using our public lands to help lead the U.S. toward a low-carbon future, as states pursue 100% renewable electricity goals nationwide. The bill outlines a commonsense approach for federal agencies to play a meaningful role in combatting climate change.

Hydro One launches Ultra-Low Overnight Electricity Price Plan

Ultra-Low Overnight Price Plan delivers flexible electricity pricing from Hydro One and the Ontario Energy Board, with TOU, tiered options, off-peak EV charging savings, balanced billing, and an online calculator to optimize bills.

 

Key Points

An Ontario pricing option with ultra-low night rates, helping Hydro One customers save by shifting usage to off-peak.

✅ Four periods with ultra-low overnight rate for EV charging

✅ Compare TOU vs tiered with Hydro One's online calculator

✅ Balanced billing and due date choice support budget control

 

Hydro One has announced that customers have even more choice and flexibility when it comes to how they are billed for electricity with the company's launch of the Ontario Energy Board's new Ultra-Low Overnight Electricity Price Plan for customers. A new survey of Ontario customers, conducted by Innovative Research Group, shows that 74 per cent of Ontarians find having choice between electricity pricing plans useful.

"As their trusted energy advisor, we want our customers to know we have the insights and tools to help them make the right choice when it comes to their electricity plans," said Teri French, Executive Vice President, Safety, Operations and Customer Experience. "We know that choice and flexibility are important to our customers, and we are proud to now offer them a third option so they can select the plan that best fits their lifestyle."

The same survey revealed that fewer than half of Ontarians are familiar with either tiered or the new ultra-low overnight price plans. To better support its customers Hydro One is providing an online calculator to help them choose which pricing plan best suits their lifestyle. The company also offers additional flexibility and assistance in managing household budgets by providing customers with the ability to choose their billing due date and flatten usage spikes from temperature fluctuations through balanced billing.

During the pandemic, Ontario introduced electricity relief to support families, small businesses and farms, complementing these customer options.

"By offering families and small businesses more choice, we are putting them back in control of their energy bills," said Todd Smith, Minister of Energy. "Starting today Hydro One customers have a new option - the Ultra-Low Electricity Price Plan - which could help them save money each year, while making our province's grid more efficient."

Electricity price plan options

  • New Ultra-Low Overnight price plan (ULO): Designed for customers who use more electricity at night, such as those who charge their electric vehicle, this new price plan can help customers keep costs down and take control of their electricity bill by shifting usage to the ultra-low overnight price period and related off-peak electricity rates when province-wide electricity demand is lower.
  • This plan has four price periods that are the same in the summer as they are in the winter and includes an ultra-low overnight rate.
  • Time-of-Use price plan (TOU): TOU provides customers with more control over their electricity bill by adjusting their usage habits with time-of-use rates used in other jurisdictions as well.
  • In this plan, electricity prices change throughout each weekday, when demand is on-peak, and peak hydro rates can affect overall costs.
  • Tiered price plan (RPP): Tiered pricing provides customers with the flexibility to use electricity at any time of day at the same low price up until the threshold is exceeded during the month, after that usage is charged at a higher price.
  • For residential customers, the winter period (November 1 – April 30) threshold is 1,000 kWh per month and the summer period (May 1 – October 31) threshold is 600 kWh per month. 
  • For small business customers, the threshold is 750 kWh throughout the year, while broader stable electricity pricing supports industrial and commercial companies.

Climate change poses high credit risks for nuclear power plants: Moody's

Nuclear Plant Climate Risks span flood risk, heat stress, and water scarcity, threatening operations, safety systems, and steam generation; resilience depends on mitigation investments, cooling-water management, and adaptive maintenance strategies.

 

Key Points

Climate-driven threats to nuclear plants: floods, heat, and water stress requiring resilience and mitigation.

✅ Flooding threats to safety and cooling systems

✅ Heat stress reduces thermal efficiency and output

✅ Water scarcity risks limit cooling capacity

 

 

Climate change can affect every aspect of nuclear plant operations like fuel handling, power and steam generation and the need for resilient power systems planning, maintenance, safety systems and waste processing, the credit rating agency said.

However, the ultimate credit impact will depend upon the ability of plant operators to invest in carbon-free electricity and other mitigating measures to manage these risks, it added.
Close proximity to large water bodies increase the risk of damage to plant equipment that helps ensure safe operation, the agency said in a note.

Moody’s noted that about 37 gigawatts (GW) of U.S. nuclear capacity is expected to have elevated exposure to flood risk and 48 GW elevated exposure to combined rising heat, extreme heat costs and water stress caused by climate change.

Parts of the Midwest and southern Florida face the highest levels of heat stress, while the Rocky Mountain region and California face the greatest reduction in the availability of future water supply, illustrating the need for adapting power generation to drought strategies, it said.

Nuclear plants seeking to extend their operations by 20, or even 40 years, beyond their existing 40-year licenses in support of sustaining U.S. nuclear power and decarbonization face this climate hazard and may require capital investment adjustments, Moody’s said, as companies such as Duke Energy climate report respond to investor pressure for climate transparency.

“Some of these investments will help prepare for the increasing severity and frequency of extreme weather events, highlighting that the US electric grid is not designed for climate impacts today.”

Extensive Disaster Planning at Electric & Gas Utilities Means Lights Will Stay On

Utility Pandemic Preparedness strengthens grid resilience through continuity planning, critical infrastructure protection, DOE-DHS coordination, onsite sequestration, skeleton crews, and deferred maintenance to ensure reliable electric and gas service for commercial and industrial customers.

 

Key Points

Plans that sustain grid operations during outbreaks using staffing limits, access controls, and deferred maintenance.

✅ Deferred maintenance and restricted site access

✅ Onsite sequestering and skeleton crew operations

✅ DOE-DHS coordination and control center staffing

 

Commercial and industrial businesses can rest assured that the current pandemic poses no real threat to our utilities, with the U.S. grid remaining reliable for now, as disaster planning has been key to electric and gas utilities in recent years, writes Forbes. Beginning a decade ago, the utility and energy industries evolved detailed pandemic plans, outlining what to know about the U.S. grid during outbreaks, which include putting off maintenance and routine activities until the worst of the pandemic has passed, restricting site access to essential personnel, and being able to run on a skeleton crew as more and more people become ill, a capability underscored by FPL's massive Irma response when crews faced prolonged outages.

One possible outcome of the current situation is that the US electric industry may require essential staff to live onsite at power plants and control centers, similar to Ontario work-site lockdown plans under consideration, if the outbreak worsens; bedding, food and other supplies are being stockpiled, reflecting local response preparations many utilities practice, Reuters reported. The Great River Energy cooperative, for example, has had a plan to sequester essential staff in place since the H1N1 bird flu crisis in 2009. The cooperative, which runs 10 power plants in Minnesota, says its disaster planning ensured it has enough cots, blankets and other necessities on site to keep staff healthy.

Electricity providers are now taking part in twice-weekly phone calls with officials at the DOE, the Department of Homeland Security, and other agencies, as Ontario demand shifts are monitored, according to the Los Angeles Times. By planning for a variety of worst case scenarios, including weeks-long restorations after major storms, “I have confidence that the sector will be prepared to respond no matter how this evolves,” says Scott Aaronson, VP of security and preparedness for the Edison Electric Institute.

Electricity is civilization": Winter looms over Ukraine battlefront

Ukraine Power Grid Restoration accelerates across liberated Kharkiv, restoring electricity, heat, and water amid missile and drone strikes, demining operations, blackouts, and winterization efforts, showcasing resilience, emergency repairs, and critical infrastructure recovery.

 

Key Points

Ukraine's rapid push to repair war-damaged grids, restore heat and water, and stabilize key services before winter.

✅ Priority repairs restore electricity and water in liberated Kharkiv.

✅ Crews de-mine lines and work under shelling, drones, and missiles.

✅ Winterization adds generators, mobile stoves, and large firewood supplies.

 

On the freshly liberated battlefields of northeast Ukraine, a pile of smashed glass windows outside one Soviet-era block of apartments attests to the violence of six months of Russian occupation, and of Ukraine’s sweeping recent military advances.

Indoors, in cramped apartments, residents lived in the dark for weeks on end.

Now, with a hard winter looming, they marvel at the speed and urgency with which Ukrainian officials have restored another key ingredient to their survival: electric power, a critical effort to keep the lights on this winter across communities.

Among those things governments strive to provide are security, opportunity, and minimal comfort. With winter approaching, and Russia targeting Ukraine’s infrastructure, add to that list heat and light, even as Russia hammers power plants nationwide. It’s requiring a concerted effort.

“Thank God it works! Electricity is civilization – it is everything,” says Antonina Krasnokutska, a retired medical worker, looking affectionately at the lightbulb that came on the day before, and now burns again in her tiny spotless kitchen.

“Without electricity there is no TV, no news, no clothes washing, no charging the phone,” says Ms. Krasnokutska, her gray hair pulled back and a small crucifix around her neck.

“Before, it was like living in the Stone Age,” says her grown son, Serhii Krasnokutskyi, who is more than a head taller. “As soon as it got dark, everyone would go to sleep.”

He shows a picture on his phone from a few days earlier, of a tangle of phone and computer charging cables – including his – plugged in at a local shop with a generator.

“We are very grateful for the people who repaired this electricity, even with shelling continuing,” he says. “They have a very complicated job.”

Indeed, although a lack of power might have been a novel inconvenience during the warm summer season, it increasingly has become a matter of great urgency for Ukrainian citizens and officials.

Coping through Ukraine’s winter with dignity and any degree of security will require courage and perseverance, as the severity and suffering that the season can bring here are being weaponized by Russia, as it seeks to compensate for a string of battlefield losses.

In recent days, Russian attacks have specifically targeted Ukraine’s electrical and other civilian infrastructure – all with the apparent aim of making this winter as hard as possible for Ukrainians, even as Moscow employs other measures to spread the hardship across Europe, while Ukraine helps Spain amid blackouts through grid support.

Ukrainian President Volodymyr Zelenskyy said Monday that Russian barrages across the country with missiles and Iran-supplied kamikaze drones had destroyed 30% of Ukraine’s power stations in the previous eight days, including strikes on western Ukraine that caused outages. Thousands of towns have been left without electricity.

Kharkiv’s challenges
Emblematic of the national challenge is the one facing officials in the northeast Kharkiv region, where Ukraine recaptured more than 3,000 square miles in a September counteroffensive. Ukrainian forces are still making gains on that front, as well as in the south toward Kherson, where Wednesday Russia started evacuating civilians from the first major city it occupied, after launching its three-pronged invasion last February.

Across the Kharkiv region, Ukrainians are stockpiling as much wood, fuel, and food as possible while they still can, and adopting new energy solutions as they prepare, from sources as diverse as the floorboards of destroyed schools and the pine forests in Izium, which are pockmarked with abandoned Russian trenches adjacent to a mass burial site.

“Of course, we have this race against time,” says Serhii Mahdysyuk, the Kharkiv regional director in charge of housing, services, fuel, and energy. “Unfortunately, we probably stand in front of the biggest challenge in Ukraine.”

That is not only because of the scale of liberated territory, he says, but also because the Kharkiv region shares a long border with Russia, as well as with the Russian-controlled areas of the eastern Donbas.

“It’s a great mixture of all threats, and we are sure that shelling and bombings will continue, but we are ready for this,” says Mr. Mahdysyuk. “We know our weak spots that Russia can destroy, but we are prepared for what to do in these situations.”

Ukraine’s battlefield gains have meant a surging need to pick up the pieces after Russian occupation, even as electricity reserves are holding if no new strikes occur, to ensure habitable conditions as more and more surviving residents require services, and as others return to scenes of devastation.

Restoring electricity is the top priority, amid shifting international assistance such as the end of U.S. grid support, because that often restarts running water, too, says Mr. Mahdysyuk. But before that, the area beneath broken power lines must be de-mined.

Indeed, members of an electricity team reconnecting cables on the outskirts of Balakliia – one of the first towns to see power restored, at the end of September – say they lost two fellow workers in the previous two weeks. One died after stepping on an anti-personnel mine, another when his vehicle hit an anti-tank device.

Ukrainian electricity workers restore power lines damaged during six months of Russian military occupation in Balakliia, Ukraine, Sept. 29, 2022. Ukrainians in liberated territory say the restoration of the electrical grid, and with it often the water supply, is a return to civilization.
“For now, our biggest problem is mines,” says the team leader, who gave the name Andrii. “It’s fine within the cities, but in the fields it’s a disaster because it’s very difficult to see them. There is a lot of [them] around here – it will take years and years to get rid of.”

Yet officials only have a few weeks to execute plans to provide for hundreds of thousands of residents in this region, in their various states of need and distress. Some 50 field kitchens capable of feeding 200 to 300 people each have been ordered. Another 1,000 mobile stoves are on their way.

And authorities will provide nearly 200,000 cubic yards of firewood for those who have no access to it, and may have no other means of keeping warm – or where shelling continues to disrupt repairs, says Mr. Mahdysyuk.

“The level of opportunity and resources we have is not the same as the level of destruction,” he says. People in districts and buildings too destroyed to have services restored soon, such as in Saltivka in Kharkiv city, may be moved.
