According to the National Lighting Bureau (NLB), just-released NEMA Lighting Systems Index data reveal fourth-quarter-2008 lighting-equipment shipments to be the lowest in the IndexÂ’ history, a dubious distinction previously held by third-quarter 2008 Index performance, when shipments contracted 4.3% from the second quarter.
In its latest tumble, the Index contracted 4.8 percent from the third quarter to the fourth, resulting in a year-over-year decline of 11.2 percent.
Established in 1998, the NEMA Lighting Systems Index is a composite measure of lamps, luminaires, ballasts, emergency lighting, exit signs, and other lighting products shipped nationally and internationally from the United States by the 450 companies that comprise the National Electrical Manufacturers Association (NEMA), one of the National Lighting BureauÂ’s founding sponsors.
NEMA members manufacture a wide range of products used in the generation, transmission, distribution, and control of electricity, as well as innumerable end-use products in addition to those used in lighting.
The value of NEMA membersÂ’ annual shipments totals $100 billion.
The Index uses 2002 data for its 100-point benchmark; fourth-quarter 2008 performance receded to the 87-point level.
NLB Communications Director John P. Bachner commented that “the residential market’s desultory condition is a major factor in the decline. Homebuilding is at its lowest level on record and a turn-around is unlikely this year. Large inventories of foreclosed homes are glutting local markets, and consumers’ ability to buy is hampered by growing joblessness and tighter lending requirements. Even compact fluorescent-lamp sales have declined, because incandescent lamps are cheaper to purchase.”
The only glimmering for the past year has emanated from the nonresidential market, and now thatÂ’s started to fade, too. According to NEMA Economic Analysis Director Brian Lego, overall construction of lodging, office, retail, and other new income properties fell for the second consecutive quarter, and more declines are predicted.
“Virtually all major end markets for lighting equipment are struggling,” he said, adding that the first quarter of 2009 is not likely to show any improvement.
Germany's Economic Downturn reflects an energy crisis, deindustrialization risks, export weakness, and manufacturing stress, amid Russia gas loss, IMF and EU recession forecasts, and debates over electricity price caps and green transition.
Key Points
An economic contraction from energy price shocks, export weakness, and bottlenecks in manufacturing and digitization.
✅ Energy shock after loss of cheap Russian gas
✅ Exports slump amid China slowdown and weak demand
✅ Policy gridlock on power price cap and permits
Germany went from envy of the world to the worst-performing major developed economy. What happened?
For most of this century, Germany racked up one economic success after another, dominating global markets for high-end products like luxury cars and industrial machinery, selling so much to the rest of the world that half the economy ran on exports.
Jobs were plentiful, the government’s financial coffers grew as other European countries drowned in debt, and books were written about what other countries could learn from Germany.
No longer. Now, Germany is the world’s worst-performing major developed economy, with both the International Monetary Fund and European Union expecting it to shrink this year.
It follows Russia’s invasion of Ukraine and the loss of Moscow’s cheap Russian gas that underpinned industry — an unprecedented shock to Germany’s energy-intensive industries, long the manufacturing powerhouse of Europe.
The sudden underperformance by Europe’s largest economy has set off a wave of criticism, handwringing and debate about the way forward.
Germany risks “deindustrialization” as high energy costs and government inaction on other chronic problems threaten to send new factories and high-paying jobs elsewhere, said Christian Kullmann, CEO of major German chemical company Evonik Industries AG.
From his 21st-floor office in the west German town of Essen, Kullmann points out the symbols of earlier success across the historic Ruhr Valley industrial region: smokestacks from metal plants, giant heaps of waste from now-shuttered coal mines, a massive BP oil refinery and Evonik’s sprawling chemical production facility.
These days, the former mining region, where coal dust once blackened hanging laundry, is a symbol of the energy transition, as the power sector’s balancing act continues with wind turbines and green space.
The loss of cheap Russian natural gas needed to power factories “painfully damaged the business model of the German economy,” Kullmann told The Associated Press. “We’re in a situation where we’re being strongly affected — damaged — by external factors.”
After Russia cut off most of its gas to the European Union, spurring an energy crisis in the 27-nation bloc that had sourced 40% of the fuel from Moscow, the German government asked Evonik to turn to coal by keeping its 1960s coal-fired power plant running a few months longer.
The company is shifting away from the plant — whose 40-story smokestack fuels production of plastics and other goods — to two gas-fired generators that can later run on hydrogen amid plans to become carbon neutral by 2030 and following the nuclear phase-out of recent years.
One hotly debated solution: a government-funded cap on industrial electricity prices to get the economy through the renewable energy transition, amid an energy crisis that even saw a temporary nuclear extension to stabilize supply.
The proposal from Vice Chancellor Robert Habeck of the Greens Party has faced resistance from Chancellor Olaf Scholz, a Social Democrat, and pro-business coalition partner the Free Democrats. Environmentalists say it would only prolong reliance on fossil fuels, while others advocate a nuclear option to meet climate goals.
Kullmann is for it: “It was mistaken political decisions that primarily developed and influenced these high energy costs. And it can’t now be that German industry, German workers should be stuck with the bill.”
The price of gas is roughly double what it was in 2021, with a senior official arguing nuclear would do little to solve that gas issue, hurting companies that need it to keep glass or metal red-hot and molten 24 hours a day to make glass, paper and metal coatings used in buildings and cars.
A second blow came as key trade partner China experiences a slowdown after several decades of strong economic growth.
These outside shocks have exposed cracks in Germany’s foundation that were ignored during years of success, including lagging use of digital technology in government and business and a lengthy process to get badly needed renewable energy projects approved.
Duke Energy Net Metering Proposal updates rooftop solar compensation with time-of-use rates, lower grid credits, and a minimum charge, aligning payments with electricity demand in North Carolina pending regulators' approval.
Key Points
A plan to swap flat credits for time-of-use rates and a minimum charge for rooftop solar customers in North Carolina.
✅ Time-of-use credits vary by grid demand
✅ $10 minimum use charge plus $14 basic fee
✅ Aims to align solar payouts with actual electricity value
Duke Energy has proposed new rules for how owners of rooftop solar panels are paid for electricity they send to the electric grid. It could mean more complexity and lower payments, but the utility says rates would be fairer.
State legislators have called for changes in the payment rules — known as "net metering" policies that allow households to sell power back to energy firms.
Right now, solar panel owners who produce more electricity than they need get credits on their bills, equal to whatever they pay for electricity. Under the proposed changes, the credit would be lower and would vary according to electricity demand, said Duke spokesperson Randy Wheeless.
"So in a cold winter morning, like now, you would get more, but maybe in a mild spring day, you would get less," Wheeless said Tuesday. "So, it better reflects what the price of electricity is."
Besides setting rates by time of use, solar owners also would have to pay a minimum of $10 a month for electricity, even if they don't use any from the grid. That's on top of Duke's $14 basic charge. Duke said it needs the extra revenue to pay for grid infrastructure to serve solar customers.
The proposal is the result of an agreement between Duke and solar industry groups — the North Carolina Sustainable Energy Association; the Southern Environmental Law Center, which represented Vote Solar and the Southern Alliance for Clean Energy; solar panel maker Sunrun Inc.; and the Solar Energy Industries Association.
The deal is similar to one approved by regulators in South Carolina last year, while in Nova Scotia a solar charge was delayed after controversy.
Daniel Brookshire of the North Carolina Sustainable Energy Association said he hopes the agreement will help the solar industry.
"We reached an agreement here that we think will provide certainty over the next decade, at least, for those interested in pursuing solar for their homes, and for our members who are solar installers," Brookshire said.
But other environmental and consumer groups oppose the changes, amid debates over who pays for grid upgrades elsewhere. Jim Warren with NC WARN said the rules would slow the expansion of rooftop solar in North Carolina.
"It would make it even harder for ordinary people to go solar," Warren said. "This would make it more complicated and more expensive, even for wealthier homeowners."
State regulators still must approve the proposal, even as courts weigh aspects of the electricity monopoly in related solar cases. If state regulators approve it, rates for new net metering customers would take effect Jan. 1, 2023.
Cement-Based Conductive Composite transforms concrete into power by energy harvesting via triboelectric nanogenerator action, carbon fibers, and built-in capacitors, enabling net-zero buildings and self-sensing structural health monitoring from footsteps, wind, rain, and waves.
Key Points
A carbon fiber cement that harvests and stores energy as electricity, enabling net-zero, self-sensing concrete.
✅ Uses carbon fibers to create a conductive concrete matrix
✅ Acts as a triboelectric nanogenerator and capacitor
✅ Enables net-zero, self-sensing structural health monitoring
Engineers from South Korea have invented a cement-based composite that can be used in concrete to make structures that generate and store electricity through exposure to external mechanical energy sources like footsteps, wind, rain and waves, and even self-powering roads concepts.
By turning structures into power sources, the cement will crack the problem of the built environment consuming 40% of the world’s energy, complementing vehicle-to-building energy strategies across the sector, they believe.
Building users need not worry about getting electrocuted. Tests showed that a 1% volume of conductive carbon fibres in a cement mixture was enough to give the cement the desired electrical properties without compromising structural performance, complementing grid-scale vanadium flow batteries in the broader storage landscape, and the current generated was far lower than the maximum allowable level for the human body.
Researchers in mechanical and civil engineering from from Incheon National University, Kyung Hee University and Korea University developed a cement-based conductive composite (CBC) with carbon fibres that can also act as a triboelectric nanogenerator (TENG), a type of mechanical energy harvester.
They designed a lab-scale structure and a CBC-based capacitor using the developed material to test its energy harvesting and storage capabilities, similar in ambition to gravity storage approaches being scaled.
“We wanted to develop a structural energy material that could be used to build net-zero energy structures that use and produce their own electricity,” said Seung-Jung Lee, a professor in Incheon National University’s Department of Civil and Environmental Engineering, noting parallels with low-income housing microgrids in urban settings.
“Since cement is an indispensable construction material, we decided to use it with conductive fillers as the core conductive element for our CBC-TENG system,” he added.
The results of their research were published this month in the journal Nano Energy.
Apart from energy storage and harvesting, the material could also be used to design self-sensing systems that monitor the structural health and predict the remaining service life of concrete structures without any external power, which is valuable in industrial settings where hydrogen-powered port equipment is being deployed.
“Our ultimate goal was to develop materials that made the lives of people better and did not need any extra energy to save the planet. And we expect that the findings from this study can be used to expand the applicability of CBC as an all-in-one energy material for net-zero energy structures,” said Prof. Lee, pointing to emerging circular battery recycling pathways for net-zero supply chains.
Publicising the research, Incheon National University quipped: “Seems like a jolting start to a brighter and greener tomorrow!”
Spain Wind Turbine Factory Shutdowns disrupt manufacturing as Vestas, Siemens Gamesa, and Nordex halt Spanish plants amid COVID-19 lockdowns, straining supply chains and renewables projects across Europe, with partial operations and maintenance continuing.
Key Points
COVID-19 lockdowns pause Spanish wind factories by Vestas, Siemens Gamesa, and Nordex, disrupting supply chains.
✅ Vestas, Siemens Gamesa, Nordex halt Spanish manufacturing
✅ Service and maintenance continue under safety protocols
✅ Supply chain and project timelines face delays in Europe
Europe’s largest wind turbine makers on Wednesday said they had shut down more factories in Spain, a major hub for the continent’s renewables sector, in response to an almost total lockdown in the country to contain the coronavirus outbreak as the Covid-19 crisis disrupts the sector.
Denmark’s Vestas, the world No.1, has suspended production at its two Spanish plants, a spokesman told Reuters, adding that its service and maintenance business was still working. Vestas has also paused manufacturing and construction in India, which is under a nationwide lockdown too, he said, and similar disruptions could stall U.S. utility solar projects this year.
Top rival Siemens Gamesa, known for its offshore wind turbine lineup, suspended production at six Spanish factories on Monday, bringing total closures there to eight, a spokeswoman said.
Four components factories are still partially up and running, at Reinosa on the north coast, Cuenca near Madrid, Mungia and Siguiero, she added.
Germany’s Nordex, the No.8 globally which is 36% owned by Spain’s Acciona, has now shuttered all of its production in Spain, even as new projects like Enel’s 90MW build move ahead, including two nacelle casing factories in Barasoain and Vall d’Uixo, as well as a rotor blade site in Lumbier.
“Production is no longer active,” a spokeswoman said in response to a Reuters query.
The new closures take the number of idled wind power factories on the continent to 19, all in Spain and Italy, the European countries worst hit by the pandemic, with investments at risk across the sector.
Spain is second only to Italy in terms of numbers of coronavirus-related fatalities and restrictions have become even stricter in the country’s third week of lockdown at a time when renewables surpassed fossil fuels for the first time in Europe.
“Some factories have temporarily paused activity as a precautionary step to strengthen sanitary measures within the sites and guarantee full compliance with government recommendations,” industry association WindEurope said, noting that wind power grows in some markets despite the pandemic.
Ontario-U.S. Energy Tariff Dispute highlights cross-border trade tensions, retaliatory tariffs, export surcharges, and White House negotiations as Doug Ford meets U.S. officials to de-escalate pressure over steel, aluminum, and energy supplies.
Key Points
A trade standoff over energy exports and tariffs, sparked by Ontario's surcharge and U.S. duties on steel and aluminum.
✅ 25% Ontario energy surcharge paused before White House talks
✅ U.S. steel and aluminum tariffs reduced from 50% to 25%
✅ Potential energy supply cutoff remains leverage in negotiations
Ontario Premier Doug Ford's recent high-stakes diplomatic trip to Washington, D.C., underscores the delicate trade tensions between Canada and the United States, particularly concerning energy exports and Canada's electricity exports across the border. Ford's potential use of tariffs or even halting U.S. energy supplies, amid Ontario's energy independence considerations, remains a powerful leverage tool, one that could either de-escalate or intensify the ongoing trade conflict between the two neighboring nations.
The meeting in Washington follows a turbulent series of events that began with Ontario's imposition of a 25% surcharge on energy exports to the U.S. This move came in retaliation to what Ontario perceived as unfair treatment in trade agreements, a step that aligned with Canadian support for tariffs at the time. In response, U.S. President Donald Trump's administration threatened its own set of tariffs, specifically targeting Canadian steel and aluminum, which further escalated tensions. U.S. officials labeled Ford's threat to cut off U.S. electricity exports and energy supplies as "egregious and insulting," warning of significant economic retaliation.
However, shortly after these heated exchanges, Trump’s commerce secretary, Howard Lutnick, extended an invitation to Ford for a direct meeting at the White House. Ford described this gesture as an "olive branch," signaling a potential de-escalation of the dispute. In the lead-up to this diplomatic encounter, Ford agreed to pause the energy surcharge, allowing the meeting to proceed, amid concerns tariffs could spike NY energy prices, without further escalating the crisis. Trump's administration responded by lowering its proposed 50% tariff on Canadian steel and aluminum to a more manageable 25%.
The outcome of the meeting, which is set to address these critical issues, could have lasting implications for trade relations between Canada and the U.S. If Ford and Lutnick can reach an agreement, the potential for tariff imposition on energy exports, though experts advise against cutting Quebec's energy exports due to broader risks, could be resolved. However, if the talks fail, it is likely that both countries could face further retaliatory measures, compounding the economic strain on both sides.
As Canada and the U.S. continue to navigate these complex issues, where support for Canadian energy projects has risen, the outcome of Ford's meeting with Lutnick will be closely watched, as it could either defuse the tensions or set the stage for a prolonged trade battle.
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.
