Experts at Rensselaer Polytechnic InstituteÂ’s Lighting Research Center (LRC) estimate that about half of the approximately 13 million streetlights in the United States have the opportunity to significantly reduce energy consumption by as much as 50 percent, translating to an annual savings of 1 billion kWh, and a reduction in power plant CO2 emissions of 546,000 tons per year.

LRC researchers demonstrated in multiple field tests that, by using what they describe as a Unified System of Photometry, a street lighting system can be designed to reduce energy use while maintaining or improving perceptions of visibility, safety, and security.

“In nighttime conditions, the human eye is more sensitive to short-wavelength light, which produces ‘cool’ tones like blue or green, as opposed to long-wavelength light, which produces ‘warm’ tones like yellow and red,” said LRC Director of Energy Programs Peter Morante. “By replacing traditional, yellowish high-pressure sodium (HPS) lights with ‘cool’ white light sources, such as induction, fluorescent, ceramic metal halide, or LEDs, we can actually reduce the amount of electric power used for lighting while maintaining or even improving visibility in nighttime conditions.”

The eye has two types of visual receptors in the retina, cones and rods. The current system of photometry — the measurement of visible light in terms of human perception for certain activities like reading and seeing fine details — is based on how some cones respond to different wavelengths. Cones are the dominant visual receptor under photopic (daylight) lighting conditions. Rods function primarily under very dim conditions.

According to Morante, it is necessary to redefine the luminous efficacy functions needed for nighttime applications where electric lighting is used and both rods and cones contribute to vision The LRCÂ’s Unified System of Photometry was designed to characterize light at any level, including the mesopic level where both rods and cones operate.

LRC field demonstration results from the past few years in rural and suburban areas of Connecticut, Massachusetts, and Texas verified that by implementing the Unified System of Photometry the street lighting system consumed 30 to 50 percent less electric power and the residents believed they could see better and said they felt safer, when compared to lighting systems designed using the traditional system of photometry. The Unified System of Photometry provides an objective method for optimizing light source spectra for minimal energy use while maintaining good visibility, according to the LRC researcher team.

There is now renewed interest in the research, according to Morante, as an increasing number of cities and towns across the U.S. are examining ways to save energy either through a reduction or a change in outdoor lighting. And the interest seems to be spreading.

According to LRC Director Mark Rea, Ph.D., researchers around the world are also concluding that the current system of photometry could use some updating to better characterize light source performance under nighttime conditions. The International Commission on Illumination, also known as the CIE from its French title, the Commission Internationale de l'Eclairage, will be releasing its own form of unified photometry for outdoor lighting, explained Rea, a long-standing CIE member.

Is Ontario embracing clean power?

Ontario Clean Energy Expansion signals IESO-backed renewables, energy storage, and low-CO2 power to meet EV-driven demand, offset Pickering nuclear retirement, and balance interim gas-fired generation while advancing grid reliability, decarbonization, and net-zero targets.

 

Key Points

Ontario Clean Energy Expansion plans to grow renewables and storage, manage short-term gas, and meet rising demand.

✅ IESO long-term procurements for renewables and storage

✅ Interim reliance on gas to replace Pickering capacity

✅ Targets align with net-zero grid reliability goals

 

After cancelling hundreds of renewable power projects four years ago, the Doug Ford government appears set to expand clean energy to meet a looming electricity shortfall across the province.

Recent announcements from Ontario Energy Minister Todd Smith and the province’s electric grid management agency suggest the province plans to expand low-CO2 electricity with new wind and solar plans in the long-term, even as it ramps up gas-fired power over the next five years.

The moves are in response to an impending electricity shortfall as climate-conscious drivers switch to electric vehicles, farmers replace field crops with greenhouses and companies like ArcelorMittal Dofasco in Hamilton switch from CO2-heavy manufacturing to electricity-based production. Forecasters predict Canada will need to double its power supply by 2050.

While Ontario has a relatively low-CO2 power system, the province’s electricity supply will be reduced in 2025 when Ontario Power Generation closes the 50-year-old Pickering nuclear station, now near the end of its operating life. This will remove 3,100 megawatts of low-CO2 generation, about eight per cent of the province’s 40,000-megawatt total.

The impending closure has created a difficult situation for the Independent Electricity System Operator (IESO), the provincial agency managing Ontario’s grid. Last year, it forecasted it would need to sharply increase CO2-polluting natural gas-fired power to avoid widespread blackouts.

This would mean drivers switching to electric vehicles or companies like Dofasco cutting CO2 through electrification would end up causing higher power system emissions.

It would also fly in the face of the federal government’s ambition to create a net-zero national electricity system by 2035, a critical part of Canada’s pledge to reduce CO2 emissions to zero by 2050.

Yet the Ford government has appeared reluctant to expand clean energy. In the 2018 election, clean electricity was a key issue as it appealed to anti-turbine voters in rural Ontario and cancelled more than 700 renewable energy contracts shortly after taking office, taking 400 megawatts out of the system.

But there are signs the government is having a change of heart. IESO recently released a list of 55 companies approved to submit bids for 3,500 megawatts of long-term electricity contracts starting between 2025 and 2027, and the energy minister has outlined a plan to address growing energy needs as well.

The companies include a variety of potential producers, ranging from Canadian and global renewable companies to local utilities and small startups. Most are renewable power or energy storage companies specializing in low- or zero-emission power. IESO plans additional long-term bid offerings in the future.

This doesn’t mean gas generation will be turned off. IESO will contract yearly production from existing gas plants until 2028 (the annual contract in 2023 will be for about 2,000 megawatts). As well, IESO has issued contracts to four gas-fired producers, a small wind company and a storage company to begin production of about 700 megawatts to boost gas plant output starting between 2024 and 2026.

While this represents an expansion of existing gas-fired generation, Smith has asked IESO to report on a gas moratorium, saying he doesn’t believe new gas plants will be needed over the long term.

The NDP and Greens criticized the government for relying on gas in the near term. But clean energy advocates greeted the long-term plans positively.

The IESO process “will contribute to a clean, reliable and affordable grid,” said the Canadian Renewable Energy Association.

Rachel Doran, director of policy and strategy at Clean Energy Canada, said in an email the potential gas generation moratorium “is an encouraging step forward,” although she criticized the “unfortunate decision to replace near-term nuclear power capacity with climate-change-causing natural gas.”

There will have to be a massive clean energy expansion to green Ontario’s grid well beyond what has been announced in recent days for Ontario to meet its future energy needs (think a doubling of Ontario’s current 40,000-megawatt capacity by 2050).

But these first steps hold promise that Ontario is at least starting on the path to that goal, rather than scrambling to keep the lights on with CO2-polluting natural gas.

Residential electricity use -- and bills -- on the rise thanks to more working from home

Work From Home Energy Consumption is driving higher electricity bills as residential usage rises. Smart meter data, ISO-New-England trends, and COVID-19 telecommuting show stronger power demand and sensitivity to utility rates across regions.

 

Key Points

Higher household electricity use from telecommuting, shifting load to residences and raising utility bills.

✅ Smart meters show 5-22 percent residential usage increases.

✅ Commercial demand fell as home cooling and IT loads rose.

✅ Utility rates and AC use drive bill spikes during summer.

 

Don't be surprised if your electric bills are looking higher than usual, with a sizable increase in the amount of power that you have used.

Summer traditionally is a peak period for electricity usage because of folks' need to run fans and air-conditioners to cool their homes or run that pool pump. But the arrival of the coronavirus and people working from home is adding to amount of power people are using.

Under normal conditions, those who work in their employer's offices might not be cooling their homes as much during the middle of the day or using as much electricity for lights and running computers.

For many, that's changed.

Estimates on how much of an increase residential electric customers are seeing as result of working from home vary widely.

ISO-New England, the regional electric grid operator, has seen a 3 percent to 5 percent decrease in commercial and industrial power demand, even as the grid overseer issued pandemic warnings nationally. The expectation is that much of that decrease translates into a corresponding increase in residential electricity usage.

But other estimates put the increase in residential electricity usage much higher. A Washington state company that makes smart electric meters, Itron, estimates that American households are using 5 percent to 10 percent more electricity per month since March, when many people began working from home as part of an effort to prevent the spread of the coronavirus.

Another smart metering company, Cambridge, Mass.-based Sense, found that average home electricity usage increased 22 percent in April compared to the same period in 2019, a reflection of people using more electricity while they stayed home. Based on its analysis of data from 5,000 homes across 30 states, Sense officials said a typical customer's monthly electric bill increased by between $22 and $25, with a larger increase for consumers in states with higher electricity rates.

Connecticut-specfic data is harder to come by.

Officials with Orange-based United Illuminating declined to provide any customer usage data, though, like others in the power industry, they did acknowledge that residential customers are using more electricity. And the state's other large electric distribution utility, Eversource, was unable to provide any recent data on residential electric usage. The company did tell Connecticut utility regulators there was a 3 percent increase in residential power usage for the week of March 21 compared to the week before.

Over the same time period, Eversource officials saw a 3 percent decrease in power usage by commercial and industrial customers.

Separately, nuclear plant workers raised concerns about pandemic precautions at some facilities, reflecting operational strains.

Alan Behm of Cheshire said he normally uses 597 kilowatt hours of electricity during an average month. But in April of this year, the amount of electricity he used rose by nearly 51 percent.

With many offices closed, the expense of heating, cooking and lighting is being shifted from employer to employee, and some utilities such as Manitoba Hydro have pursued unpaid days off to trim costs during the pandemic. And one remote work expert believes some companies are recognizing the burden those added costs are placing on workers -- and are trying to do something about it.

Technology giant Google announced in late May that it was giving employees who work from home $1,000 allowances to cover equipment costs and other expenses associated with establishing a home office.

Moe Vela, chief transparency officer for the New York City-based computer software company TransparentBusiness, said the move by Google executives is a savvy one.

"Google is very smart to have figured this out," Vela said. "This is what employees want, especially millenials. People are so much happier to be working remotely, getting those two to three hours back per day that some people spend getting to and from work is so much more important than a stipend."

Vela predicted that even after a vaccine is found for the corona virus, one of the key worklife changes is likely to be a broader acceptance of telework and working from home.

Beyond the immediate shifts, more young Canadians would work in electricity if awareness improved, pointing to future talent pipelines.

"I think that's where we're headed," he said. "I think it will make an employer more attractive as they try to attract talent from around the world."

Vela said employers save an average of $11,000 per year for each employee they have working from home.

"It would be a brilliant move if a company were to share some of that amount with employees," he said. "I wouldn't do it if it's going to cause a company to not be there (in business) though."

The idea of a company sharing whatever savings it achieves by having employees work from home wasn't well received by many Connecticut residents who responded to questions posed via social media by Hearst Connecticut Media. More than 100 people responded and an overwhelming number of people spoke out against the idea.

"You are saving on gas and other travel related expenses, so the small increase in your electric bill shouldn't really be a concern," said Kathleen Bennett Charest of Wallingford.

Jim Krupp, also of Wallingford, said, "to suggest that the employers compensate the employees makes as much sense as suggesting that the employees should take a pay cut due to their reduced expenses for travel, day care, and eating lunch at work."

"Employers must still maintain their offices and incur all of the fixed expenses involved, including basic utilities, taxes and insurance," Krupp said. "The cost savings (for employers) that are realized are also offset by increased costs of creating and maintaining IT networks that allow employees to access their work sites from home and the costs of monitoring and managing the work force."

Kiki Nichols Nugent of Cheshire said she was against the idea of an employee trying to get their employer to pay for the increased electricity costs associated with working from home.

"I would not nickle and dime," Nugent said. "If companies are saving on electricity now, maybe employers will give better raises next year."

New Haven resident Chris Smith said he is "just happy to have a job where I am able to telecommute."

"When teleworking becomes more the norm, either now or in the future, we may see increased wages for teleworkers either for the lower cost to the employer or for the increase in productivity it brings," Smith said.

Restrict price charged for gas and electricity - British MPs

UK Energy Price Cap aims to protect consumers on gas and electricity bills, tackling Big Six overcharging on default and standard variable tariffs, with Ofgem and MPs pushing urgent reforms to the broken market.

 

Key Points

A temporary absolute limit on default energy tariffs to shield consumers from overcharging on gas and electricity bills.

✅ Caps standard variable and default tariffs to protect loyalty.

✅ Targets Big Six pricing; oversight by Ofgem and BEIS MPs.

✅ Aims for winter protection while maintaining competition.

 

MPs are calling for a cap on the price of gas and electricity, with questions over the expected cost of a UK price cap amid fears consumers are being ripped off.

The Business, Energy and Industrial Strategy (BEIS) Select Committee says the Big Six energy companies have been overcharging for years.

MPs on the committee backed plans for a temporary absolute cap, noting debates over EU gas price cap strategies to fix what they called a "broken" energy market.

Labour's Rachel Reeves, who chairs the committee, said: "The energy market is broken. Energy is an essential good and yet millions of customers are ripped off for staying loyal to their energy provider.

"An energy price cap is now necessary and the Government must act urgently to ensure it is in place to protect customers next winter.

"The Big Six energy companies might whine and wail about the introduction of a price cap but they've been overcharging their customers on default and SVTs (standard variable tariffs) for years and their recent feeble efforts to move consumers off these tariffs has only served to highlight the need for this intervention."

The Committee also criticised Ofgem for failing to protect customers, especially the most vulnerable.

Draft legislation for an absolute cap on energy tariffs was published by the Government last year, and later developments like the Energy Security Bill have kept reform on the agenda.

But Business Secretary Greg Clark refused to guarantee that the flagship plans would be in place by next winter, despite warnings about high winter energy costs for households.

Committee members said there was a "clear lack of will" on the part of the Big Six to do what was necessary, including exploring decoupling gas and electricity prices, to deal with pricing problems.

A report from the committee found that customers are paying £1.4bn a year more than they should be under the current system.

Around 12 million households are stuck on poor-value tariffs, according to the report.

National assistance charity Citizens Advice said "loyal and vulnerable" customers had been "ripped off" for too long.

Chief executive Gillian Guy said: "An absolute cap, as recommended by the committee, is crucial to securing protection for the largest number of customers while continuing to provide competition in the market. This should apply to all default tariffs."

Magnitude 5 quake strikes near Iran nuclear plant

Iran Bushehr Earthquake rattles southern province near the Bushehr nuclear power plant, USGS reports M5.1 at 38 km depth; seismic activity along major fault lines raises safety, damage, and monitoring concerns.

 

Key Points

A magnitude 5.1 quake near Bushehr nuclear plant at 38 km depth, with no damage reported, per USGS.

✅ USGS lists magnitude 5.1 at 38 km depth

✅ Near Bushehr nuclear power plant; built for stronger quakes

✅ Iran lies on major fault lines; quake risk is frequent

 

A magnitude 5 earthquake struck southern Iran early Friday near the Islamic Republic's only nuclear power plant. There were no immediate reports of damage or injuries as Iran continues combined-cycle conversions across its power sector.

The quake hit Iran's Bushehr province at 5:23 a.m., according to the U.S. Geological Survey. It put the magnitude at 5.1 and the depth of the earthquake at 38 kilometres (24 miles), in a province tied to efforts to transmit electricity to Europe in coming years.

Iranian state media did not immediately report on the quake. However, the Bushehr nuclear power plant was designed to withstand much stronger earthquakes, a notable consideration as Iraq plans nuclear power plants to address shortages.

A magnitude 5 earthquake can cause considerable damage, including power disruptions that have seen blackouts spark protests in some Iranian cities.

Iran sits on major fault lines and is prone to near-daily earthquakes, yet it remains a key player in regional power, with Iran-Iraq energy cooperation ongoing. In 2003, a 6.6-magnitude quake flattened the historic city of Bam, killing 26,000 people, and today Iran supplies 40% of Iraq's electricity through cross-border power deals. Bam is near the Bushehr nuclear plant, which wasn’t damaged at that time, while more recently Iran finalized deals to rehabilitate Iraq's power grid to improve resilience.

If B.C. wants to electrify all road vehicles by 2055, it will need to at least double its power output: study

B.C. EV Electrification 2055 projects grid capacity needs doubling to 37 GW, driven by electric vehicles, renewable energy expansion, wind and solar generation, limited natural gas, and policy mandates for zero-emission transportation.

 

Key Points

A projection that electrifying all B.C. road transport by 2055 would more than double grid demand to 37 GW.

✅ Site C adds 1.1 GW; rest from wind, solar, limited natural gas.

✅ Electricity price per kWh rises 9%, but fuel savings offset.

✅ Significant GHG cuts with 93% renewable grid under Clean Energy Act.

 

Researchers at the University of Victoria say that if B.C. were to shift to electric power for all road vehicles by 2055, the province would require more than double the electricity now being generated.

The findings are included in a study to be published in the November issue of the Applied Energy journal.

According to co-author and UVic professor Curran Crawford, the team at the university's Pacific Institute for Climate Solutions took B.C.'s 2015 electrical capacity of 15.6 gigawatts as a baseline, and added projected demands from population and economic growth, then added the increase that shifting to electric vehicles would require, while acknowledging power supply challenges that could arise.

They calculated the demand in 2055 would amount to 37 gigawatts, more than double 15.6 gigawatts used in 2015 as a baseline, and utilities warn of a potential EV charging bottleneck if demand ramps up faster than infrastructure.

"We wanted to understand what the electricity requirements are if you want to do that," he said. "It's possible — it would take some policy direction."

B.C. announces $4M in rebates for home and work EV charging stations across the province
The team took the planned Site C dam project into account, but that would only add 1.1 gigawatts of power. So assuming no other hydroelectric dams are planned, the remainder would likely have to come from wind and solar projects and some natural gas.

"Geothermal and biomass were also in the model," said Crawford, adding that they are more expensive electricity sources. "The model we were using, essentially, we're looking for the cheapest options."

(Eric Woolliscroft/CBC)
The electricity bill, per kilowatt hour, would increase by nine per cent, according to the team's research, but Crawford said getting rid of the gasoline and diesel now used to fuel vehicles could amount to an overall cost saving, especially when combined with zero-emission vehicle incentives available to consumers.

The province introduced a law this year requiring that all new light-duty vehicles sold in B.C. be zero emission by 2040, while the federal 2035 EV mandate adds another policy signal, so the researchers figured 2055 was a reasonable date to imagine all vehicles on the road to be electric.

Crawford said hydrogen-powered vehicles weren't considered in the study, as the model used was already complicated enough, but hydrogen fuel would actually require more electricity for the electrolysis, when compared to energy stored in batteries.

Electric vehicles are approaching a tipping point as faster charging becomes more available — here's why
The study also found that shifting to all-electric ground transportation in B.C. would also mean a significant decrease in greenhouse gas emissions, assuming the Clean Energy Act remains in place, which mandates that 93 per cent of grid electricity must come from renewable resources, whereas nationally, about 18 per cent of electricity still comes from fossil fuels, according to 2019 data. 

"Doing the electrification makes some sense — If you're thinking of spending some money to reduce carbon emissions, this is a pretty cost effective way of doing that," said Crawford.

OSW CareerMatch Offshore Wind Job Fair convenes industry leaders, supply chain employers, and skilled candidates at IPF 2020 in Providence, Rhode Island, spotlighting workforce development, training programs, and near-term hiring for U.S. offshore wind projects.

 

Key Points

An IPF 2020 job fair connecting offshore wind employers, advancing workforce development in Providence, RI.

✅ National job fair at IPF 2020, Providence, RI

✅ Connects supply chain employers with skilled candidates

✅ Includes a workforce development and education summit

 

The Business Network for Offshore Wind, the leading non-profit advocate for U.S. offshore wind at the state, federal and global levels, amid a U.S. grid warning about coronavirus impacts, will host its seventh annual International Partnership Forum (IPF) on April 21-24, 2020 in Providence, Rhode Island. 

New this year: the first-ever national offshore wind industry job fair plus a half-day workforce development summit, in partnership with Skills for Rhode Island’s Future. The OSW CareerMatch, will showcase jobs at top-tier companies seeking to grow the workforce of the future, informed by young people's interest in electricity careers, and recruit qualified candidates. The Offshore Wind Workforce Development and Education Summit, an invitation-only event, will bring together educators, stakeholders, and industry leaders to address current energy training programs, identify industry employment needs, required skillsets, and how organizations can fulfill these near-term needs. CareerMatch will take place 8:30 a.m. to 1:00 p.m. on Tuesday, April 21, and the Workforce Summit from 12:30 p.m. to 4:00 p.m., both at the Rhode Island Convention Center. 

“The U.S. offshore wind industry has reached the stage that, in order to successfully develop and meet new project demands, will require an available and qualified workforce,” said Liz Burdock, CEO and president of the Business Network for Offshore Wind, noting worker safety concerns in other energy sectors. “This first-ever national Job Fair will allow top-tier supply chain companies to connect with skilled individuals to discuss projects that are going on as they speak.” 

“Hosting the first-of-its-kind offshore wind energy job fair in The Ocean State is apropos,” said Nina Pande, executive director of Skills for Rhode Island’s Future, as future of work investments accelerate across the electricity sector. “Our organization is thrilled to have the unique opportunity to help convene talent at OSW CareerMatch to engage with the employers across the offshore wind supply chain.”

The annual IPF conference is the premier event for the offshore wind supply chain, which is now projected to be a $70 billion revenue opportunity through 2030. Fully developing this supply chain will foster local economic growth, provide thousands of jobs, adapt to shifts like working from home electricity demand, and help offshore wind energy meet its potential. If fully built out worldwide, offshore wind could power 18 times the world’s current electricity needs.    

The exhibit and conference sells out every year and is again on track to draw over 2,500 industry professionals representing over 575 companies, all focused on sharing valuable insights on how to move the emerging U.S. wind industry forward, including operational resilience such as on-site staffing plans during the outbreak. The full conference schedule may be seen online here. More details, including special guest speakers, will be announced soon.
