Manpower is tweaking candlepower as it seeks the sweet spot in the automated lighting systems for its new downtown Milwaukee headquarters.
Late-night observers who noticed the building fully lighted along the Milwaukee River earlier this month should start getting a dimmer view. The 5,100 or so lights inside the four-story building were set to go off from 7:30 p.m. to 5:30 a.m. Most of the lights at Manpower's riverside plaza fade out at 10 p.m.
The light show reflects how the global employment services company is balancing aesthetics and efficiency. Manpower is seeking "green" certification of its building under the Leadership in Energy and Environmental Design rating system. But it also wants to keep a spotlight on its $78 million headquarters, what Mayor Tom Barrett has hailed as "front and center" in Milwaukee's renaissance.
"We do want to be energy efficient, of course," said Jennifer Dettman, director of strategic sourcing and corporate real estate for Manpower. "But we also want to make sure that we stay in tune with the look and the feel of downtown and how it is lit up at night." Manpower will continue working with contractors to fine tune the lighting system, Dettman said.
She expects strategic exterior lights to stay on, including those on the flags - which represent a fraction of the 73 countries where Manpower has offices - and the water wall. All of those fixtures are energy efficient and shine downward, minimizing light pollution, Dettman said.
The 280,000-square-foot building is positioned to use daylight to illuminate more than 90% of the work spaces for the headquarters' 900 employees. Interior lights by the windows can automatically dim by 50% when the sun shines. Other lights use occupancy sensors to shut off when no one is around. Overall, the lighting remains a work in progress, Dettman said.
"We will probably continue to look at even further tuning down some of the lights as we take a look at it in the evenings," Dettman said.
H2 Gateway Hydrogen Network accelerates clean energy in B.C., building electrolysis plants and hydrogen fueling stations for zero-emission vehicles, heavy-duty trucks, and long-haul transit, supporting decarbonization, green hydrogen supply, and infrastructure investment.
Key Points
A $900M B.C. initiative by HTEC to build electrolysis plants and 20 hydrogen fueling stations for zero-emission transport.
✅ $900M project with HTEC, CIB, and B.C. government
✅ 3 electrolysis plants plus byproduct liquefaction in North Vancouver
✅ Up to 20 stations; 14 for heavy-duty vehicles in B.C. and Alberta
British Columbia is taking a significant step towards a cleaner future with a brand new $900 million project. This initiative, spearheaded by hydrogen company HTEC and supported by the CIB in B.C. and the B.C. government, aims to establish a comprehensive hydrogen network across the province. This network will encompass both hydrogen production plants and fueling stations, marking a major leap in developing hydrogen infrastructure in B.C.
The project, dubbed "H2 Gateway," boasts several key components. At its core lies the construction of three brand new electrolysis hydrogen production plants. These facilities will be strategically located in Burnaby, Nanaimo, and Prince George, ensuring a wide distribution of hydrogen fuel. An additional facility in North Vancouver will focus on liquefying byproduct hydrogen, maximizing resource efficiency.
The most visible aspect of H2 Gateway will undoubtedly be the network of hydrogen fueling stations. The project envisions up to 20 stations spread across British Columbia and Alberta, complementing the province's Electric Highway build-out, with 18 being situated within B.C. itself. This extensive network will significantly enhance the accessibility of hydrogen fuel, making it a more viable option for motorists. Notably, 14 of these stations will be designed to handle heavy-duty vehicles, catering to the transportation sector's clean energy needs.
The economic and environmental benefits of H2 Gateway are undeniable. The project is expected to generate nearly 300 jobs, aligning with recent grid job creation efforts, providing a much-needed boost to the B.C. economy. More importantly, the widespread adoption of hydrogen fuel promises significant reductions in greenhouse gas emissions. Hydrogen-powered vehicles produce zero tailpipe emissions, making them a crucial tool in combating climate change.
British Columbia's investment in hydrogen infrastructure aligns with a global trend. As countries strive to achieve ambitious climate goals, hydrogen is increasingly viewed as a promising clean energy source. Hydrogen fuel cells offer several advantages over traditional electric vehicles, and while B.C. leads the country in going electric, they boast longer driving ranges and shorter refueling times, making them particularly attractive for long-distance travel and heavy-duty applications.
While H2 Gateway represents a significant step forward, challenges remain. The production of clean hydrogen, often achieved through electrolysis using renewable energy sources, faces power supply challenges and requires substantial initial investment. Additionally, the number of hydrogen-powered vehicles on the road is still relatively low.
However, projects like H2 Gateway are crucial in overcoming these hurdles. By creating a robust hydrogen infrastructure, B.C. is sending a strong signal to the industry and, alongside BC Hydro's EV charging expansion across southern B.C., is building a comprehensive clean transportation network. This investment will not only benefit the environment but also incentivize the development and adoption of hydrogen-powered vehicles. As the technology matures and production costs decrease, hydrogen fuel has the potential to revolutionize transportation and play a key role in a sustainable future.
The road ahead for hydrogen may not be entirely smooth, but British Columbia's commitment to H2 Gateway demonstrates a clear vision. By investing in clean energy infrastructure, the province is not only positioning itself as a leader in the fight against climate change, with Canada and B.C. investing in green energy solutions to accelerate progress, but also paving the way for a more sustainable transportation landscape.
Texas Gulf Coast Power Outages from Harvey continue as flooding, high winds, and downed lines paralyze Houston and coastal utilities, while restoration crews from out-of-state work to repair infrastructure and restore electricity across impacted communities.
Key Points
Power disruptions across Houston and the Gulf Coast from Harvey, driven by flooding, wind damage, and blocked access.
✅ CenterPoint warns multi-day outages in flooded zones.
✅ AEP Texas aided by crews from Kentucky, Illinois, Missouri.
✅ Entergy expects more outages as storm nears Galveston.
Hundreds of thousands of Texans were without power along the Gulf Coast as Tropical Storm Harvey left parts of the Houston area under water, with extended Houston outages compounding response efforts.
There were roughly 280,000 customers without power along the Texas's coast and in Houston and the surrounding areas on Monday, according to reported outages by the state's investor-owned utilities. Harvey, which made landfall on Friday, caused devastating flooding and knocked out power lines along its destructive path, similar to the Louisiana grid rebuild after Laura that required weeks of restoration.
CenterPoint Energy reported more than 100,000 outages earlier on Monday, though that figure was down to 91,744 shortly after 1 p.m. on Monday.
The company said it was unable to access hard-hit areas until floodwaters recede and electric infrastructure dries out, a challenge that, as seen in Florida power restoration efforts elsewhere, has taken weeks to resolve. Outages in the most flooded areas could last for several days, CenterPoint warned.
AEP Texas's coverage area south of Houston had 150,500 customers without electricity as of 11 a.m. ET on Monday. That was down from the peak of its outages on Saturday afternoon, which affected 220,000 customers.
Former FEMA deputy director: Texas has already begun recovery from storm 1:54 PM ET Mon, 28 Aug 2017 | 05:57
Corpus Christi and the surrounding areas along the Gulf Coast were still experiencing the most outages, while persistent Toronto outages after a spring storm underscored how long recovery can take in urban areas. AEP credited assistance from out-of-state workers for helping to get the lights back on.
"Thousands of resources have arrived from across the country to help AEP Texas with restoration efforts following this historic weather event. Crews from Kentucky, Illinois, Missouri and other states have arrived and are working on restoring power to those impacted by Hurricane Harvey," AEP said in a statement.
Entergy reported 29,500 customers were without power on Monday in areas north of Houston. The company warned that additional outages were expected if Harvey moves inland near the island city of Galveston on Wednesday as anticipated, a pattern similar to New Orleans during Ida where electricity failed despite levees holding.
Houston, Beaumont and Victoria are expected to see continued periods of torrential rain through Tuesday, before Harvey begins to move north on Wednesday and out of the flood zone by Thursday.
"Our crews are safely restoring power as quickly as possible, but the continued wind, rain and flooding are having an impact on restoration efforts," Entergy said in a statement.
South of Houston, about 7,500 Texas New Mexico Power Company customers were still experiencing outages, according to the company's outage map.
Ontario Nuclear Refurbishment Economic Impact powers growth as Bruce Power's MCR and OPG's Darlington unit 2 refurbishment drive jobs, supply-chain spending, medical isotopes, clean baseload power, and lower GHG emissions across Ontario and Canada.
Key Points
It is the measured gains from Bruce Power's MCR and OPG's Darlington refurbishment in jobs, taxes, and clean energy.
✅ CAD7.6B-10.6B impact in Ontario; CAD8.1B-11.6B nationwide.
✅ Supports 60% nuclear supply, jobs, and medical isotopes.
✅ MCR and Darlington cut GHGs, drive innovation and supply chains.
The 13-year Major Component Replacement (MCR) project being undertaken as part of Bruce Power's life-extension programme, which officially began with a reactor taken offline earlier this year, will inject billions of dollars into Ontario's economy, a new report has found. Meanwhile, the major project to refurbish Darlington unit 2 remains on track for completion in 2020, Ontario Power Generation (OPG) has announced.
The Ontario Chamber of Commerce (OCC) said its report, Major Component Replacement Project Economic Impact Analysis, outlines an impartial assessment of the MCR programme and related manufacturing contracts across the supply chain. The report was commissioned by Bruce Power.
"Our analysis shows that Bruce Power's MCR project is a fundamental contributor to the Ontario economy. More broadly, the life-extension of the Bruce Power facility will provide quality jobs for Ontarians, produce a stable supply of medical isotopes for the world's healthcare system, and deliver economic benefit through direct and indirect spending," OCC President and CEO Rocco Rossi said."As Ontario's energy demand grows, nuclear truly is the best option to meet those demands with reduced GHG [greenhouse gas] emissions. The Bruce Power MCR Project will not only drive economic growth in the region, it will position Ontario as a global leader in nuclear innovation and expertise."
According to the OCC's economic analysis, the MCR's economic impact on Ontario is estimated to be between CAD7.6 billion (USD5.6 billion) and CAD10.6 billion. Nationally, its economic impact is estimated to be between CAD8.1 billion and CAD11.6 billion. It estimates that the federal government will receive CAD144 million in excise tax and CAD1.2 billion in income tax, while the provincial government will receive CAD300 million and CAD437 million. Ontario’s municipal governments are estimated to receive a collective CAD192 million in tax.
The nuclear industry currently provides 60% of Ontario’s daily energy supply needs, with Pickering life extension plans bolstering system reliability, and is made up of over 200 companies and more than 60,000 jobs across a diversity of sectors such as operations, manufacturing, skilled trades, healthcare, and research and innovation, the report notes.
Greg Rickford, Ontario's minister of Energy, Northern Development and Mines, and minister of Indigenous Affairs, said continued use of the Bruce generating station which recently set an operating record would create jobs and advance Ontario’s nuclear industrial sector. "It is great to see projects like the MCR that help make Ontario the best place to invest, do business and find a job," he said.
The MCR is part of Bruce Power's overall life-extension programme, which started in January 2016. Bruce 6 will be the first of the six Candu units to undergo an MCR which will take 46 months to complete and give the unit a further 30-35 years of operational life. The total cost of refurbishing Bruce units 3-8 is estimated at about CAD8 billion, in addition to CAD5 billion on other activities under the life-extension programme, which is scheduled for completion by 2053.
Darlington milestones
OPG's long-term refurbishment programme at Darlington, alongside SMR plans for the site announced by the province, began with unit 2 in 2016 after years of detailed planning and preparation. Reassembly of the reactor, which was disassembled last year, is scheduled for completion this spring, and the unit 2 refurbishment project remains on track for completion in early 2020. At the same time, final preparations are under way for the start of the refurbishment of unit 3.
"We've entered a critical phase on the project," Senior Vice President of Nuclear Refurbishment Mike Allen said. "OPG and our project partners continue to work as an integrated team to meet our commitments on Unit 2 and our other three reactors at Darlington Nuclear Generating Station."
A 350-tonne generator stator manufactured by GE in Poland is currently in transit to Canada, where it will be installed in Darlington 3's turbine hall as the province also breaks ground on its first SMR this year.
The 10-year Darlington refurbishment is due to be completed in 2026, while the province plans to refurbish Pickering B to extend output beyond that date.
UK Nuclear Power Expansion is vital for low-carbon baseload, energy security, and Net Zero, complementing renewables like wind and solar, reducing gas reliance, and unlocking investment through clear financing rules and proven, dependable reactor technology.
Key Points
Accelerating reactor build-out for low-carbon baseload to boost energy security and help deliver the UK Net Zero target.
✅ Cuts gas dependence and stabilizes grids with firm capacity.
✅ Complements wind and solar for reliable, low-carbon supply.
✅ Needs clear financing to unlock investment and lower costs.
Leading nuclear industry figures will today call for a major programme of new power stations to hit ambitious emissions reduction targets.
The 19th Nuclear Industry Association annual conference in London will highlight the need for a proven, dependable source of low carbon electricity generation alongside growth in weather-dependent solar and wind power, and particularly the rapid expansion of wind and solar generation across the UK.
Without this, they argue, the country risks embedding a major reliance on carbon-emitting gas fired power stations as Europe loses nuclear capacity at a critical time for energy security for generations to come.
Annual public opinion polling released today to coincide with the conference revealed 75% of the population want the UK Government to take more action to reduce CO2 emissions.
The survey, conducted by YouGov in October 2019, has tracked opinion trends on nuclear for more than a decade. It shows continued and consistent public support for an energy mix including nuclear and renewables, with 72% of respondents agreeing this was needed to ensure a reliable supply of electricity.
Nuclear power was also perceived as the most secure energy source for keeping the lights on, compared to other sources such as oil, gas, coal, wind power, fracking and solar power.
Last month both the Labour and Conservative Parties committed to new nuclear power as part of their election Manifestos and the government's wider green industrial revolution plans for clean growth. At the same time, 27 leading figures in the fields of environment, energy, and industry signed an open letter addressed to parliamentary candidates, which set out the benefits of nuclear and underscored the consequences of not, at least, replacing the UK's current fleet of power stations.
The Nuclear Industry Association said there is no time to be lost in clarifying the ambition and the financing rules for new nuclear power which would bring down costs and unlock a major programme of investment.
Tom Greatrex, Chief Executive of the NIA, said "We have to grow the industry's contribution to a low carbon economy. The independent Committee on Climate Change said earlier this year that we need a variety of technologies including nuclear power/1 for net zero to reach the UK's Net Zero emissions target by 2050".
"This is a proven, dependable, technology with lower lifecycle CO2 emissions than solar power and the same as offshore wind/2. It is also an important economic engine for the UK, supporting uses beyond electricity and creating high quality direct and indirect employment for around 155,000 people."
"Right now nuclear provides 20%/3 of all the UK's electricity but all but one of our existing fleet will close over the next decade, amid the debate over nuclear's decline as power demand will only increase with a shift to electric heating and vehicles."
"The countries and regions which have most successfully decarbonised, like Sweden, France and Ontario in Canada, have done so by relying on nuclear, aligning with Canada's climate goals for affordable, safe power today. You are not serious about tackling climate change if you are not serious about nuclear".
Nighttime Thermoelectric Generator converts radiative cooling into renewable energy, leveraging outer space cold; a Stanford-UCLA prototype complements solar, serving off-grid loads with low-power output during peak evening demand, using simple materials on a rooftop.
Key Points
A device converting nighttime radiative cooling into electricity, complementing solar for low-power evening needs.
✅ Uses thermocouples to convert temperature gradients to voltage.
✅ Exploits radiative cooling to outer space for night power.
✅ Complements solar; low-cost parts suit off-grid applications.
Two years ago, one freezing December night on a California rooftop, a tiny light shone weakly with a little help from the freezing night air. It wasn't a very bright glow. But it was enough to demonstrate the possibility of generating renewable power after the Sun goes down.
Working with Stanford University engineers Wei Li and Shanhui Fan, University of California Los Angeles materials scientist Aaswath Raman put together a device that produces a voltage by channelling the day's residual warmth into cooling air, effectively generating electricity from thin air with passive heat exchange.
"Our work highlights the many remaining opportunities for energy by taking advantage of the cold of outer space as a renewable energy resource," says Raman.
"We think this forms the basis of a complementary technology to solar. While the power output will always be substantially lower, it can operate at hours when solar cells cannot."
For all the merits of solar energy, it's just not a 24-7 source of power, although research into nighttime solar cells suggests new possibilities for after-dark generation. Sure, we can store it in a giant battery or use it to pump water up into a reservoir for later, but until we have more economical solutions, nighttime is going to be a quiet time for renewable solar power.
Most of us return home from work as the Sun is setting, and that's when energy demands spike to meet our needs for heating, cooking, entertaining, and lighting.
Unfortunately, we often turn to fossil fuels to make up the shortfall. For those living off the grid, it could require limiting options and going without a few luxuries.
Shanhui Fan understands the need for a night time renewable power source well. He's worked on a number of similar devices, including carbon nanotube generators that scavenge ambient energy, and a recent piece of technology that flipped photovoltaics on its head by squeezing electricity from the glow of heat radiating out of the planet's Sun-warmed surface.
While that clever item relied on the optical qualities of a warm object, this alternative device makes use of the good old thermoelectric effect, similar to thin-film waste-heat harvesting approaches now explored.
Using a material called a thermocouple, engineers can convert a change in temperature into a difference in voltage, effectively turning thermal energy into electricity with a measurable voltage. This demands something relatively toasty on one side and a place for that heat energy to escape to on the other.
The theory is the easy part – the real challenge is in arranging the right thermoelectric materials in such a way that they'll generate a voltage from our cooling surrounds that makes it worthwhile.
To keep costs down, the team used simple, off-the-shelf items that pretty much any of us could easily get our hands on.
They put together a cheap thermoelectric generator and linked it with a black aluminium disk to shed heat in the night air as it faced the sky. The generator was placed inside a polystyrene enclosure sealed with a window transparent to infrared light, and linked to a single tiny LED.
For six hours one evening, the box was left to cool on a roof-top in Stanford as the temperature fell just below freezing. As the heat flowed from the ground into the sky, the small generator produced just enough current to make the light flicker to life.
At its best, the device generated around 0.8 milliwatts of power, corresponding to 25 milliwatts of power per square metre.
That might just be enough to keep a hearing aid working. String several together and you might just be able to keep your cat amused with a simple laser pointer. So we're not talking massive amounts of power.
But as far as prototypes go, it's a fantastic starting point. The team suggests that with the right tweaks and the right conditions, 500 milliwatts per square metre isn't out of the question.
"Beyond lighting, we believe this could be a broadly enabling approach to power generation suitable for remote locations, and anywhere where power generation at night is needed," says Raman.
While we search for big, bright ideas to drive the revolution for renewables, it's important to make sure we don't let the smaller, simpler solutions like these slip away quietly into the night.
Global Electricity Demand Surge strains power markets, fuels price volatility, and boosts coal and gas generation as renewables lag, driving emissions, according to the IEA, with grids and clean energy investment crucial through 2024.
Key Points
A surge in power use that strained supply, raised prices, and drove power-sector CO2 emissions to record highs.
✅ 6% demand growth in 2021; largest absolute rise ever
✅ Coal up 9%; gas +2%; renewables +6% could not meet demand
✅ Prices doubled vs 2020; volatility hit EU, China, India
Global electricity demand surged above pre-pandemic levels in 2021, creating strains in major markets, pushing prices to unprecedented levels and driving the power sector’s emissions to a record high. Electricity is central to modern life and clean electricity is pivotal to energy transitions, but in the absence of faster structural change in the sector, rising demand over the next three years could result in additional market volatility and continued high emissions, according an IEA report released today.
Driven by the rapid economic rebound, and more extreme weather conditions than in 2020, including a colder than average winter, last year’s 6% rise in global electricity demand was the largest in percentage terms since 2010 when the world was recovering from the global financial crisis. In absolute terms, last year’s increase of over 1 500 terawatt-hours was the largest ever, according to the January 2022 edition of the IEA’s semi-annual Electricity Market Report.
The steep increase in demand outstripped the ability of sources of electricity supply to keep pace in some major markets, with shortages of natural gas and coal leading to volatile prices, demand destruction and negative effects on power generators, retailers and end users, notably in China, Europe and India. Around half of last year’s global growth in electricity demand took place in China, where demand grew by an estimated 10%, highlighting that Asia is set to use half of global electricity by 2025 according to the IEA. China and India suffered from power cuts at certain points in the second half of the year because of coal shortages.
“Sharp spikes in electricity prices in recent times have been causing hardship for many households and businesses around the world and risk becoming a driver of social and political tensions,” said IEA Executive Director Fatih Birol. “Policy makers should be taking action now to soften the impacts on the most vulnerable and to address the underlying causes. Higher investment in low-carbon energy technologies including renewables, energy efficiency and nuclear power – alongside an expansion of robust and smart electricity grids – can help us get out of today’s difficulties.”
The IEA’s price index for major wholesale electricity markets almost doubled compared with 2020 and was up 64% from the 2016-2020 average. In Europe, average wholesale electricity prices in the fourth quarter of 2021 were more than four times their 2015-2020 average, and wind and solar generated more electricity than gas in the EU during the year. Besides Europe, there were also sharp price increases in Japan and India, while they were more moderate in the United States where gas supplies were less perturbed.
Electricity produced from renewable sources grew by 6% in 2021, but it was not enough to keep up with galloping demand. Coal-fired generation grew by 9%, with soaring electricity and coal use serving more than half of the increase in demand and reaching a new all-time peak as high natural gas prices led to gas-to-coal switching. Gas-fired generation grew by 2%, while nuclear increased by 3.5%, almost reaching its 2019 levels. In total, carbon dioxide (CO2) emissions from power generation rose by 7%, also reaching a record high, after having declined the two previous years.
“Emissions from electricity need to decline by 55% by 2030 to meet our Net Zero Emissions by 2050 Scenario, but in the absence of major policy action from governments, those emissions are set to remain around the same level for the next three years,” said Dr Birol. “Not only does this highlight how far off track we currently are from a pathway to net zero emissions by 2050, but it also underscores the massive changes needed for the electricity sector to fulfil its critical role in decarbonising the broader energy system.”
For 2022-2024, the report anticipates electricity demand growing 2.7% a year on average, although the Covid-19 pandemic and high energy prices bring some uncertainty to this outlook. Renewables are set to grow by 8% per year on average, and low-emissions sources are expected to serve more than 90% of net demand growth during this period. We expect nuclear-based generation to grow by 1% annually during the same period.
As a consequence of slowing electricity demand growth and significant renewables additions, fossil fuel-based generation is expected to stagnate in the coming years, and renewables are set to surpass coal by 2025 with coal-fired generation falling slightly as phase-outs and declining competitiveness in the United States and Europe are balanced by growth in markets like China, where electricity demand trends remain a puzzle in recent analyses, and India. Gas-fired generation is seen growing by around 1% a year.
