More than $50 billion is being wasted each year by the owners of 2.8 million U.S. commercial, industrial, and institutional buildings that rely on outmoded lighting systems that waste energy and money, especially when they fail to deliver the array of High-Benefit Lighting” savings otherwise available.

Citing a letter issued by Secretary of Energy Samuel W. Bodman, National Lighting Bureau Chair Robert W. Colgan, Jr. noted that “the return on investment that can be generated by upgrading these outmoded systems will never be better. The Commercial Building Tax Deduction [CBTD] introduced through the Energy Policy Act of 2005 has been extended through December 31, 2013. The CBTD gives owners a tax benefit of as much as 60 cents per square foot for qualifying lighting systems, effectively lowering the investment required to update or replace an outmoded system.

“The return – in the form of utility bill savings and the bottom-line benefits of providing better seeing conditions – creates a genuinely huge financial incentive at a time when building owners could really use one.”

In his letter to building-industry leaders, Secretary Bodman wrote, “More than 75 percent of the Nation’s five million commercial, industrial, and institutional buildings were built prior to the introduction of many groundbreaking energy efficient technologies currently available today. These buildings consume nearly 900 billion kilowatt-hours of electricity, at a cost exceeding $115 billion each year. While cost-effective lighting technologies are available now to cut energy costs by up to 50 percent, only 25 percent of the buildings have been upgraded.”

Mr. Colgan said that the upgrade incentives comprise far more than the tax benefits that can significantly offset the capital investment required to improve. “The energy cost savings can be substantial,” he said, noting that, using Department of Energy estimates, lighting upgrades alone could avoid some $50 billion of needless energy expense each year.

“But energy savings are only part of the picture,” he added, commenting that most of the buildings in question also pay “demand charges,” that is, fees imposed by electric utilities based on the maximum amount of electricity the buildings use during a given “demand interval,” often a period of 15 consecutive minutes.

Mr. Colgan explained, “Although two utility customers may consume the identical amount of electricity in a month, the utility will have to invest far more to meet the demands of a customer that uses that amount all in one day versus the customer that consumes about 3.33 percent of the amount each day of the month. Demand charges typically are imposed on nonresidential customers as separate elements of the utility bill, and they can in some cases amount to as much as or even more than energy charges.”

Despite the often-substantial savings afforded by lower utility bills, the most significant value likely to be derived from lighting-system upgrades comes from what the National Lighting Bureau calls High-Benefit Lighting; that is, lighting systems designed specifically for the tasks, workers, and spaces involved. According to Mr. Colgan, “National Lighting Bureau case histories show that, when new or upgraded lighting is well-designed, properly installed, and commissioned to ensure it achieves the design intent, people can perform their tasks faster and with fewer errors.

“Consider this: A two-shift, 100-person-per-shift manufacturer may spend about $15,000 per year on lighting energy when it operates six days per week. If so, a 70% energy-use reduction would yield an energy-cost benefit of $10,500 per year. If that same new lighting were well-designed and so improved worker productivity by just 2% per year, the manufacturer would derive an additional benefit worth about $150,000 per year.”

Productivity improvements are not the only benefits of High-Benefit Lighting, Mr. Colgan said. He commented that additional benefits stem from fewer errors, fewer accidents, reduced absenteeism, improved security, increased retail sales, and, in a number of cases, higher resale value for the property involved.

And still, thatÂ’s not all.

“The nation’s number-one source of greenhouse gas emissions is coal-fired power plants,” Mr. Colgan said. “Reducing electrical requirements reduces the amount of coal burned each year and that can have an extremely positive effect on our environment, and can significantly reduce the costs we’d otherwise have to bear to clean up the pollution involved and counteract the warming effects otherwise created.”

Mr. Colgan commented that the CBTD applies to more than lighting and, for that reason, the National Electrical Manufacturers Association – a founder and long-term sponsor of the National Lighting Bureau – has been working with Secretary Bodman in developing a multifaceted, national energy-conservation effort.

As Secretary Bodman wrote, “I challenged the National Electrical Manufacturers Association (NEMA) to commit to a national building energy efficiency campaign…[and] NEMA has responded with enthusiasm, resources, and dedication….The benefits to be gained from its initiative are described in detail at its website, www.NEMAsaveseneregy.org.”

“There are so many right reasons for upgrading or replacing outmoded lighting systems right now,” Mr. Colgan said. “And the return on one’s investment can be truly spectacular.”

Lighting-system designers available to help achieve High-Benefit Lighting in every state of the union are listed at the National Lighting Bureau website (www.nlb.org).

“We identified these people and are providing their listings at no charge to help jump-start the decision process,” Mr. Colgan said. “We have encouraged every lighting-system designer in the nation to sign up.”

The Bureau’s website also provides guidance on how to select lighting-system designers and lists individuals who are authorized to certify that a given lighting system complies with the CBTD requirements. “Lighting systems must be certified in order to be eligible for the tax deduction,” Mr. Colgan noted.

“Lighting systems can be certified by qualified contractors and engineers as well as lighting-system designers, and the Bureau invites certifying firms and individuals to list free of charge on the NLB website. We want to make it easy for businesses to take advantage of these great incentives.”

The BureauÂ’s website also provides free guidance literature, as well as numerous articles and case histories describing the benefits of High-Benefit Lighting.

Why the promise of nuclear fusion is no longer a pipe dream

ITER Nuclear Fusion advances tokamak magnetic confinement, heating deuterium-tritium plasma with superconducting magnets, targeting net energy gain, tritium breeding, and steam-turbine power, while complementing laser inertial confinement milestones for grid-scale electricity and 2025 startup goals.

 

Key Points

ITER Nuclear Fusion is a tokamak project confining D-T plasma with magnets to achieve net energy gain and clean power.

✅ Tokamak magnetic confinement with high-temp superconducting coils

✅ Deuterium-tritium fuel cycle with on-site tritium breeding

✅ Targets net energy gain and grid-scale, low-carbon electricity

 

It sounds like the stuff of dreams: a virtually limitless source of energy that doesn’t produce greenhouse gases or radioactive waste. That’s the promise of nuclear fusion, often described as the holy grail of clean energy by proponents, which for decades has been nothing more than a fantasy due to insurmountable technical challenges. But things are heating up in what has turned into a race to create what amounts to an artificial sun here on Earth, one that can provide power for our kettles, cars and light bulbs.

Today’s nuclear power plants create electricity through nuclear fission, in which atoms are split, with next-gen nuclear power exploring smaller, cheaper, safer designs that remain distinct from fusion. Nuclear fusion however, involves combining atomic nuclei to release energy. It’s the same reaction that’s taking place at the Sun’s core. But overcoming the natural repulsion between atomic nuclei and maintaining the right conditions for fusion to occur isn’t straightforward. And doing so in a way that produces more energy than the reaction consumes has been beyond the grasp of the finest minds in physics for decades.

But perhaps not for much longer. Some major technical challenges have been overcome in the past few years and governments around the world have been pouring money into fusion power research as part of a broader green industrial revolution under way in several regions. There are also over 20 private ventures in the UK, US, Europe, China and Australia vying to be the first to make fusion energy production a reality.

“People are saying, ‘If it really is the ultimate solution, let’s find out whether it works or not,’” says Dr Tim Luce, head of science and operation at the International Thermonuclear Experimental Reactor (ITER), being built in southeast France. ITER is the biggest throw of the fusion dice yet.

Its $22bn (£15.9bn) build cost is being met by the governments of two-thirds of the world’s population, including the EU, the US, China and Russia, at a time when Europe is losing nuclear power and needs energy, and when it’s fired up in 2025 it’ll be the world’s largest fusion reactor. If it works, ITER will transform fusion power from being the stuff of dreams into a viable energy source.


Constructing a nuclear fusion reactor
ITER will be a tokamak reactor – thought to be the best hope for fusion power. Inside a tokamak, a gas, often a hydrogen isotope called deuterium, is subjected to intense heat and pressure, forcing electrons out of the atoms. This creates a plasma – a superheated, ionised gas – that has to be contained by intense magnetic fields.

The containment is vital, as no material on Earth could withstand the intense heat (100,000,000°C and above) that the plasma has to reach so that fusion can begin. It’s close to 10 times the heat at the Sun’s core, and temperatures like that are needed in a tokamak because the gravitational pressure within the Sun can’t be recreated.

When atomic nuclei do start to fuse, vast amounts of energy are released. While the experimental reactors currently in operation release that energy as heat, in a fusion reactor power plant, the heat would be used to produce steam that would drive turbines to generate electricity, even as some envision nuclear beyond electricity for industrial heat and fuels.

Tokamaks aren’t the only fusion reactors being tried. Another type of reactor uses lasers to heat and compress a hydrogen fuel to initiate fusion. In August 2021, one such device at the National Ignition Facility, at the Lawrence Livermore National Laboratory in California, generated 1.35 megajoules of energy. This record-breaking figure brings fusion power a step closer to net energy gain, but most hopes are still pinned on tokamak reactors rather than lasers.

In June 2021, China’s Experimental Advanced Superconducting Tokamak (EAST) reactor maintained a plasma for 101 seconds at 120,000,000°C. Before that, the record was 20 seconds. Ultimately, a fusion reactor would need to sustain the plasma indefinitely – or at least for eight-hour ‘pulses’ during periods of peak electricity demand.

A real game-changer for tokamaks has been the magnets used to produce the magnetic field. “We know how to make magnets that generate a very high magnetic field from copper or other kinds of metal, but you would pay a fortune for the electricity. It wouldn’t be a net energy gain from the plant,” says Luce.


One route for nuclear fusion is to use atoms of deuterium and tritium, both isotopes of hydrogen. They fuse under incredible heat and pressure, and the resulting products release energy as heat


The solution is to use high-temperature, superconducting magnets made from superconducting wire, or ‘tape’, that has no electrical resistance. These magnets can create intense magnetic fields and don’t lose energy as heat.

“High temperature superconductivity has been known about for 35 years. But the manufacturing capability to make tape in the lengths that would be required to make a reasonable fusion coil has just recently been developed,” says Luce. One of ITER’s magnets, the central solenoid, will produce a field of 13 tesla – 280,000 times Earth’s magnetic field.

The inner walls of ITER’s vacuum vessel, where the fusion will occur, will be lined with beryllium, a metal that won’t contaminate the plasma much if they touch. At the bottom is the divertor that will keep the temperature inside the reactor under control.

“The heat load on the divertor can be as large as in a rocket nozzle,” says Luce. “Rocket nozzles work because you can get into orbit within minutes and in space it’s really cold.” In a fusion reactor, a divertor would need to withstand this heat indefinitely and at ITER they’ll be testing one made out of tungsten.

Meanwhile, in the US, the National Spherical Torus Experiment – Upgrade (NSTX-U) fusion reactor will be fired up in the autumn of 2022, while efforts in advanced fission such as a mini-reactor design are also progressing. One of its priorities will be to see whether lining the reactor with lithium helps to keep the plasma stable.


Choosing a fuel
Instead of just using deuterium as the fusion fuel, ITER will use deuterium mixed with tritium, another hydrogen isotope. The deuterium-tritium blend offers the best chance of getting significantly more power out than is put in. Proponents of fusion power say one reason the technology is safe is that the fuel needs to be constantly fed into the reactor to keep fusion happening, making a runaway reaction impossible.

Deuterium can be extracted from seawater, so there’s a virtually limitless supply of it. But only 20kg of tritium are thought to exist worldwide, so fusion power plants will have to produce it (ITER will develop technology to ‘breed’ tritium). While some radioactive waste will be produced in a fusion plant, it’ll have a lifetime of around 100 years, rather than the thousands of years from fission.

At the time of writing in September, researchers at the Joint European Torus (JET) fusion reactor in Oxfordshire were due to start their deuterium-tritium fusion reactions. “JET will help ITER prepare a choice of machine parameters to optimise the fusion power,” says Dr Joelle Mailloux, one of the scientific programme leaders at JET. These parameters will include finding the best combination of deuterium and tritium, and establishing how the current is increased in the magnets before fusion starts.

The groundwork laid down at JET should accelerate ITER’s efforts to accomplish net energy gain. ITER will produce ‘first plasma’ in December 2025 and be cranked up to full power over the following decade. Its plasma temperature will reach 150,000,000°C and its target is to produce 500 megawatts of fusion power for every 50 megawatts of input heating power.

“If ITER is successful, it’ll eliminate most, if not all, doubts about the science and liberate money for technology development,” says Luce. That technology development will be demonstration fusion power plants that actually produce electricity, where advanced reactors can build on decades of expertise. “ITER is opening the door and saying, yeah, this works – the science is there.”

Is Hydrogen The Future For Power Companies?

Hydrogen Energy Transition accelerates green hydrogen, electrolyzers, renewables, and fuel cells, as the EU and US scale decarbonization, NextEra tests hydrogen-to-power, and DOE funds pilots to replace natural gas and cut CO2.

 

Key Points

A shift to deploy green hydrogen tech to decarbonize power, industry, and transport across EU and US energy systems.

✅ EU targets 40 GW electrolyzers plus 40 GW imports by 2030

✅ DOE funds pilots; NextEra trials hydrogen-to-power at Okeechobee

✅ Aims to replace natural gas, enable fuel cells, cut CO2

 

Last month, the European Union set out a comprehensive hydrogen strategy as part of its goal to achieve carbon neutrality for all its industries by 2050. The EU has an ambitious target to build out at least 40 gigawatts of electrolyzers within its borders by 2030 and also support the development of another 40 gigawatts of green hydrogen in nearby countries that can export to the region by the same date. The announcement came as little surprise, given that Europe is regarded as being far ahead of the United States in the shift to renewable energy, even as it looks to catch up on fuel cells with Asian leaders today.

But the hydrogen bug has finally arrived stateside: The U.S. Department of Energy has unveiled the H2@Scale initiative whereby a handful of companies including Cummins Inc. (NYSE: CMI), Caterpillar Inc.(NYSE: CAT), 3M Company (NYSE: MMM), Plug Power Inc.(NASDAQ: PLUG) and EV startup Nikola Corp.(NASDAQ: NKLA), even as the industry faces threats to the EV boom that investors are watching, will receive $64 million in government funding for hydrogen research projects.

Hot on the heels of the DoE initiative: American electric utility and renewable energy giant, NextEra Energy Inc.(NYSE: NEE), has unveiled an equally ambitious plan to start replacing its natural gas-powered plants with hydrogen.

During its latest earnings call, NextEra’s CFO Rebecca Kujawa said the company is “…particularly excited about the long-term potential of hydrogen” and discussed plans to start a pilot hydrogen project at one of its generating stations at Okeechobee Clean Energy Center owned by its subsidiary, Florida Power & Light (FPL). NextEra reported Q2 revenue of $4.2B (-15.5% Y/Y), which fell short of Wall Street’s consensus by $1.12B while GAAP EPS of $2.59 (+1.1% Y/Y) beat estimates by $0.09. The company attributed the big revenue slump to the effects of Covid-19.

Renewable energy and hydrogen stocks have lately become hot property as EV adoption hits an inflection point worldwide, with NEE up 16% in the year-to-date; PLUG +144%, Bloom Energy Corp. (NYSE: BE) +62.8% while Ballard Power Systems (NASDAQ: BLDP) has gained 98.2% over the timeframe.

NextEra’s usual modus operandi involves conducting small experiments with new technologies to establish their cost-effectiveness, a pragmatic approach informed by how electricity changed in 2021 across the grid, before going big if the trials are successful.

CFO Kujawa told analysts:
“Based on our ongoing analysis of the long-term potential of low-cost renewables, we remain confident as ever that wind, solar, and battery storage will be hugely disruptive to the country’s existing generation fleet, while reducing cost for customers and helping to achieve future CO2 emissions reductions. However, to achieve an emissions-free future, we believe that other technologies will be necessary, and we are particularly excited about the long-term potential of hydrogen.”

NextEra plans to test the electricity-to-hydrogen-to-electricity model at its natural gas-powered Okeechobee Clean Energy Center that came online in 2019. Okeechobee is already regarded as one of the cleanest thermal energy facilities anywhere on the globe. However, replacing natural gas with zero emissions hydrogen would be a significant step in helping the company achieve its goal to become 100% emissions-free by 2050.

Kujawa said the company plans to continue evaluating other potential hydrogen opportunities to accelerate the decarbonization of transportation fuel, amid the debate over the future of vehicles between electricity and hydrogen, and industrial feedstock and also support future demand for low-cost renewables.

Another critical milestone: NextEra finished the quarter with a renewables backlog of approximately 14,400 megawatts, its largest in its 20-year development history. To put that backlog into context, NextEra revealed that it is larger than the operating wind and solar portfolios of all but two companies in the world.

Hydrogen Bubble?
That said, not everybody is buying the hydrogen hype.

Barron’s Bill Apton says Wall Street has discovered hydrogen this year and that hydrogen stocks are a bubble, even as hybrid vehicles gain momentum in the U.S. market according to recent reports. Apton says the huge runup by Plug Power, Ballard Energy, and Bloom Energy has left them trading at more than 50x future cash flow, making it hard for them to grow into their steep valuations. He notes that smaller hydrogen companies are up against big players and deep-pocketed manufacturers, including government-backed rivals in China and the likes of Cummins.

According to Apton, it could take a decade or more before environmentally-friendly hydrogen can become competitive with natural gas on a cost-basis, while new ideas like flow battery cars also vie for attention, making hydrogen stocks better long-term picks than the cult stocks they have become.

Looming Coal and Nuclear Plant Closures Put ‘Just Transition’ Concept to the Test

Just Transition for Coal and Nuclear Workers explains policy frameworks, compensation packages, retraining, and community support during decarbonization, plant closures, and energy shifts across Europe and the U.S., including Diablo Canyon and Uniper strategies.

 

Key Points

A policy approach to protect and retrain legacy power workers as coal and nuclear plants retire during decarbonization.

✅ Germany and Spain fund closures with compensation and retraining.

✅ U.S. lacks federal support; Diablo Canyon is a notable exception.

✅ Firms like Uniper convert coal sites to gas and clean energy roles.

 

The coronavirus pandemic has not changed the grim reality facing workers at coal and nuclear power plants in the U.S. and Europe. How those workers will fare in the years ahead will vary greatly based on where they live and the prevailing political winds.

In Europe, the retirement of aging plants is increasingly seen as a matter of national concern. Germany this year agreed to a €40 billion ($45 billion) compensation package for workers affected by the country's planned phaseout of coal generation by 2038, amid its broader exit from nuclear power as part of its energy transition. Last month the Spanish authorities agreed on a just transition plan affecting 2,300 workers across 12 thermal power plants that are due to close this year.

In contrast, there is no federal support plan for such workers in the U.S., said Tim Judson, executive director at the Maryland-based Nuclear Information and Resource Service, which lobbies for an end to nuclear and fossil-fuel power.

For all of President Donald Trump’s professed love of blue-collar workers in sectors such as coal, “where there are economic transitions going on, we’re terrible at supporting workers and communities,” Judson said of the U.S. Even at the state level, support for such workers is "almost nonexistent,” he said, “although there are a lot of efforts going on right now to start putting in place just transition programs, especially for the energy sector.”

One example that stands out in the U.S. is the support package secured for workers at utility PG&E's Diablo Canyon Power Plant, California's last operating nuclear power plant that is scheduled for permanent closure in 2025. “There was a settlement between the utility, environmental groups and labor unions to phase out that plant that included a very robust just transition package for the workers and the local community,” Judson said.

Are there enough clean energy jobs to replace those being lost?
Governments are more likely to step in with "just transition" plans where they have been responsible for plant closures in the first place. This is the case for California, Germany and Spain, all moving aggressively to decarbonize their energy sectors and pursue net-zero emissions policy goals.

Some companies are beginning to take a more proactive approach to helping their workers with the transition. German energy giant Uniper, for example, is working with authorities to save jobs by seeking to turn coal plants into lower-emissions gas-fired units.

Germany’s coal phaseout will force Uniper to shut down 1.5 gigawatts of hard-coal capacity by 2022, but the company has said it is looking at "forward-looking" options for its plants that "will be geared toward tomorrow's energy world and offer long-term employment prospects."

Christine Bossak, Uniper’s manager of external communications, told GTM this approach would be adopted in all the countries where Uniper operates coal plants.

Job losses are usually inevitable when a plant is closed, Bossak acknowledged. “But the extent of the reduction depends on the alternative possibilities that can be created at the site or other locations. We will take care of every single employee, should he or she be affected by a closure. We work with the works council and our local partners to find sustainable solutions.”

Diana Junquera Curiel, energy industry director for the global union federation IndustriALL, said such corporate commitments looked good on paper — but the level of practical support depends on the prevailing political sentiment in a country, as seen in Germany's nuclear debate over climate strategy.

Even in Spain, where the closure of coal plants was being discussed 15 years ago, a final agreement had to be rushed through at the last minute upon the arrival of a socialist government, Junquera Curiel said. An earlier right-wing administration had sat on the plan for eight years, she added.

The hope is that heel-dragging over just transition programs will diminish as the scale of legacy plant closures grows.

Nuclear industry facing a similar challenge as coal
One reason why government support is so important is there's no guarantee a burgeoning clean energy economy will be able to absorb all the workers losing legacy generation jobs. Although the construction of renewable energy projects requires large crews, it often takes no more than a handful of people to operate and maintain a wind or solar plant once it's up and running, Junquera Curiel observed.

Meanwhile, the job losses are unlikely to slow. In Europe, Austria and Sweden both closed their last coal-fired units recently, even as Europe loses nuclear capacity in key markets.

In the U.S., the Energy Information Administration's base-case prediction is that coal's share of power generation will fall from 24 percent in 2019 to 13 percent in 2050, while nuclear's will fall from 20 percent to 12 percent over that time horizon. The EIA has long underestimated the growth trajectory of renewables in the mix; only in 2020 did it concede that renewables will eventually overtake natural gas as the country's largest source of power.

The Institute for Energy Economics and Financial Analysis has predicted that even a coronavirus-inspired halt to renewables is unlikely to stop a calamitous drop in coal’s contribution to U.S. generation.

The nuclear sector faces a similar challenge as coal, albeit over a longer timeline. Last year saw the nuclear industry starting to lose capacity worldwide in what could be the beginning of a terminal decline, highlighted by Germany's shutdown of its last three reactors in 2023. Last week, the Indian Point Energy Center closed permanently after nearly half a century of cranking out power for New York City.*

“Amid ongoing debates over whether to keep struggling reactors online in certain markets, the industry position would be that governments should support continued operation of existing reactors and new build as part of an overall policy to transition to a sustainable clean energy system,” said Jonathan Cobb, senior communication manager at the World Nuclear Association.

If this doesn’t happen, plant workers will be hoping they can at least get a Diablo Canyon treatment. Based on the progress of just transition plans so far, that may depend on how they vote just as much as who they work for.

Scientists generate 'electricity from thin air.' Humidity could be a boundless source of energy.

Air Humidity Energy Harvesting converts thin air into clean electricity using air-gen devices with nanopores, delivering continuous renewable energy from ambient moisture, as demonstrated by UMass Amherst researchers in Advanced Materials.

 

Key Points

A method using nanoporous air-gen devices to harvest continuous clean electricity from ambient atmospheric moisture.

✅ Nanopores drive charge separation from ambient water molecules

✅ Works across materials: silicon, wood, bacterial films

✅ Predictable, continuous power unlike intermittent solar or wind

 

Sure, we all complain about the humidity on a sweltering summer day. But it turns out that same humidity could be a source of clean, pollution-free energy, aligning with efforts toward cheap, abundant electricity worldwide, a new study shows.

"Air humidity is a vast, sustainable reservoir of energy that, unlike wind and solar power resources, is continuously available," said the study, which was published recently in the journal Advanced Materials.

While humidity harvesting promises constant output, advances like a new fuel cell could help fix renewable energy storage challenges, researchers suggest.

“This is very exciting,” said Xiaomeng Liu, a graduate student at the University of Massachusetts-Amherst, and the paper’s lead author. “We are opening up a wide door for harvesting clean electricity from thin air.”

In fact, researchers say, nearly any material can be turned into a device that continuously harvests electricity from humidity in the air, a concept echoed by raindrop electricity demonstrations in other contexts.

“The air contains an enormous amount of electricity,” said Jun Yao, assistant professor of electrical and computer engineering at the University of Massachusetts-Amherst and the paper’s senior author. “Think of a cloud, which is nothing more than a mass of water droplets. Each of those droplets contains a charge, and when conditions are right, the cloud can produce a lightning bolt – but we don’t know how to reliably capture electricity from lightning.

"What we’ve done is to create a human-built, small-scale cloud that produces electricity for us predictably and continuously so that we can harvest it.”

The heart of the human-made cloud depends on what Yao and his colleagues refer to as an air-powered generator, or the "air-gen" effect, which relates to other atmospheric power concepts like night-sky electricity studies in the field.

In broader renewable systems, flexible resources such as West African hydropower can support variable wind and solar output, complementing atmospheric harvesting concepts as they mature.

The study builds on research from a study published in 2020. That year, scientists said this new technology "could have significant implications for the future of renewable energy, climate change and in the future of medicine." That study indicated that energy was able to be pulled from humidity by material that came from bacteria; related bio-inspired fuel cell design research explores better electricity generation, the new study finds that almost any material, such as silicon or wood, also could be used.

The device mentioned in the study is the size of a fingernail and thinner than a single hair. It is dotted with tiny holes known as nanopores, it was reported. "The holes have a diameter smaller than 100 nanometers, or less than a thousandth of the width of a strand of human hair."

Why California's Climate Policies Are Causing Electricity Blackouts

California Rolling Blackouts expose grid reliability risks amid a heatwave, as CAISO curtails power while solar output fades at sunset, wind stalls, and scarce natural gas and nuclear capacity plus PG&E issues strain imports.

 

Key Points

Grid outages during heatwaves from low reserves, fading solar, weak wind, and limited firm capacity.

✅ Heatwave demand rose as solar output dropped at sunset

✅ Limited imports and gas, nuclear shortfalls cut reserves

✅ Policy, pricing, and maintenance gaps increased outage risk

 

Millions of Californians were denied electrical power and thus air conditioning during a heatwave, raising the risk of heatstroke and death, particularly among the elderly and sick. 

The blackouts come at a time when people, particularly the elderly, are forced to remain indoors due to Covid-19, and as later heat waves would test the grid again statewide.

At first, the state’s electrical grid operator last night asked customers to voluntarily reduce electricity use. But after lapses in power supply pushed reserves to dangerous levels it declared a “Stage 3 emergency” cutting off power to people across the state at 6:30 pm.

The immediate reason for the black-outs was the failure of a 500-megawatt power plant and an out-of-service 750-megawatt unit not being available. “There is nothing nefarious going on here,” said a spokeswoman for California Independent System Operator (CAISO). “We are just trying to run the grid.”

But the underlying reasons that California is experiencing rolling black-outs for the second time in less than a year stem from the state’s climate policies, which California policymakers have justified as necessary to prevent deaths from heatwaves, and which it is increasingly exporting to Western states as a model.

In October, Pacific Gas and Electric cut off power to homes across California to avoid starting forest fires after reports that its power lines may have started fires in recent seasons. The utility and California’s leaders had over the previous decade diverted billions meant for grid maintenance to renewables. 

And yesterday, California had to impose rolling blackouts because it had failed to maintain sufficient reliable power from natural gas and nuclear plants, or pay in advance for enough guaranteed electricity imports from other states.

It may be that California’s utilities and their regulator, the California Public Utilities Commission, which is also controlled by Gov. Newsom, didn’t want to spend the extra money to guarantee the additional electricity out of fears of raising California’s electricity prices even more than they had already raised them.

California saw its electricity prices rise six times more than the rest of the United States from 2011 to 2019, helping explain why electricity prices are soaring across the state, due to its huge expansion of renewables. Republicans in the U.S. Congress point to that massive increase to challenge justifications by Democrats to spend $2 trillion on renewables in the name of climate change.

Even though the cost of solar panels declined dramatically between 2011 and 2019, their unreliable and weather-dependent nature meant that they imposed large new costs in the form of storage and transmission to keep electricity as reliable. California’s solar panels and farms were all turning off as the blackouts began, with no help available from the states to the East already in nightfall.

Electricity from solar goes away at the very moment when the demand for electricity rises. “The peak demand was steady in late hours,” said the spokesperson for CAISO, which is controlled by Gov. Gavin Newsom, “and we had thousands of megawatts of solar reducing their output as the sunset.”

The two blackouts in less than a year are strong evidence that the tens of billions that Californians have spent on renewables come with high human, economic, and environmental costs.

Last December, a report by done for PG&E concluded that the utility’s customers could see blackouts double over the next 15 years and quadruple over the next 30.

California’s anti-nuclear policies also contributed to the blackouts. In 2013, Gov. Jerry Brown forced a nuclear power plant, San Onofre, in southern California to close.

Had San Onofre still been operating, there almost certainly would not have been blackouts on Friday as the reserve margin would have been significantly larger. The capacity of San Onofre was double that of the lost generation capacity that triggered the blackout.

California's current and former large nuclear plants are located on the coast, which allows for their electricity to travel shorter distances, and through less-constrained transmission lines than the state’s industrial solar farms, to get to the coastal cities where electricity is in highest demand.

There has been very little electricity from wind during the summer heatwave in California and the broader western U.S., further driving up demand. In fact, the same weather pattern, a stable high-pressure bubble, is the cause of heatwaves, since it brought very low wind for days on end along with very high temperatures.

Things won’t be any better, and may be worse, in the winter, with a looming shortage as it produces far less solar electricity than the summer. Solar plus storage, an expensive attempt to fix problems like what led to this blackout, cannot help through long winters of low output.

California’s electricity prices will continue to rise if it continues to add more renewables to its grid, and goes forward with plans to shut down its last nuclear plant, Diablo Canyon, in 2025.

Had California spent an estimated $100 billion on nuclear instead of on wind and solar, it would have had enough energy to replace all fossil fuels in its in-state electricity mix.

To manage the increasingly unreliable grid, California will either need to keep its nuclear plant operating, build more natural gas plants, underscoring its reliance on fossil fuels for reliability, or pay ever more money annually to reserve emergency electricity supplies from its neighbors.

After the blackouts last October, Gov. Newsom attacked PG&E Corp. for “greed and mismanagement” and named a top aide, Ana Matosantos, to be his “energy czar.” 

“This is not the new normal, and this does not take 10 years to solve,” Newsom said. “The entire system needs to be reimagined.”

Yet another Irish electricity provider is increasing its prices

Electric Ireland Electricity Price Increase stems from rising wholesale costs as energy suppliers adjust tariffs. Customers face higher electricity bills, while gas remains unchanged; switching provider could deliver savings during winter.

 

Key Points

A 4% increase in Electric Ireland electricity prices from 1 Feb 2018, driven by wholesale costs; gas unchanged.

✅ 4% electricity rise effective 1 Feb 2018

✅ Increase attributed to rising wholesale energy costs

✅ Switching supplier may reduce bills and boost savings

 

ELECTRIC IRELAND has announced that it will increase its household electricity prices by 4% from 1 February 2018.

This comes just a week after both Bord Gáis Energy and SSE Airtricity announced increases in their gas and electricity prices, while national efforts to secure electricity supplies continue in parallel.

Electric Ireland has said that the electricity price increase is unavoidable due to the rising wholesale cost of electricity, with EU electricity prices trending higher as well.

The electricity provider said it has no plans to increase residential gas prices at the moment.

Commenting on the latest announcement, Eoin Clarke, managing director of Switcher.ie, said: “This is the third largest energy supplier to announce a price increase in the last week, so the other suppliers are probably not far behind.

“The fact that the rise is not coming into effect until 1 February will be welcomed by Electric Ireland customers who are worried about the rising cost of energy as winter sets in,” he said.

However, any increase is still bad news, especially as a quarter of consumers (27%) say their energy bill already puts them under financial pressure, and EU energy inflation has disproportionately affected lower-income households.

According to Electric Ireland, this will amount to a €2.91 per month increase for an average electricity customer, amounting to €35 per year.

Meanwhile, SSE Airtricity’s change amounts to an increase of 90 cent per week or €46.80 per year for someone with average consumption on their 24hr SmartSaver standard tariff, far below the dramatic Spain electricity price surge seen recently.

Bord Gáis Energy said its announcement will increase a typical gas bill by €2.12 a month and a typical electricity bill by €4.77 a month, reflecting wider trends such as the Germany power price spike reported recently.

In a statement, Bord Gáis Energy said: “The changes, which will take effect from 1st November 2017, are due to significant increases in the wholesale cost of energy as well as higher costs associated with distributing energy on the gas and electricity networks.

“In percentage terms, the increase represents 3.4% in a typical customer’s gas bill and an increase of 5.9% in a typical customer’s electricity bill.”

Clark said that if customers haven’t switched electricity provider in over a year that they should review the deals available at the moment.

“The market is highly competitive so there are huge savings to be made by switching,” he said.

“All suppliers use the same cables to supply electricity to your home, so you don’t need to worry about any loss in service, and you could save up to 324 by switching from typical standard tariffs to the cheapest deals on the market.”
