Wal-Mart Stores Inc. opens its latest generation of energy-efficient test stores with a Las Vegas Supercenter that uses new cooling technology to cut overall energy use by up to 45 percent.

The Las Vegas store opening builds on advances in earlier pilot stores that reduced energy use in areas including lighting, refrigeration and water flow.

The previous pilot stores in the Midwest cut energy use up to 25 percent compared to a typical Supercenter built in 2005, the year Wal-Mart launched a broad environmental program to reduce energy use and packaging waste and to sell more sustainable products.

Wal-Mart said the new Las Vegas store adds to those savings with a new cooling system based on water evaporation for total energy savings of between 35 percent and 45 percent.

Wal-Mart has said it is the biggest private user of electricity in the world and has huge potential to cut back on greenhouse gases from fossil fuels burned to create electricity. It aims to use technologies proven in the pilot stores to develop a prototype in 2009 for all new Supercenters that will be between 25 percent and 30 percent more energy efficient.

An outside engineering and efficiency expert said Wal-Mart's advances in saving energy, including the new Las Vegas store, are leading the field for big-box retailers.

"This is not just a baby step. This is a big step," said Terry Townsend, past president of the American Society of Heating, Refrigerating and Air-Conditioning Engineers.

Townsend said Wal-Mart's pilot stores are important because they show other retailers how to use available technology to improve energy efficiency. Wal-Mart says it is sharing its lessons with retail industry groups.

The latest store is built specifically for the arid climate of Western states, where water evaporates faster than in the more-humid East.

It uses rooftop cooling towers to chill water that then runs in conduits under the floor of the store. The radiant cooling from the floor replaces traditional electricity-powered air conditioning.

The store also incorporates innovations from the previous pilot stores that include recycling heat from refrigerators and combining low-power LED lights in freezer cases with sensors that turn off those lights when no customers are around.

Germany agrees 200 bln euro package to shield against surging energy prices

Germany Energy Price Defensive Shield counters soaring gas and electricity costs with a gas price brake, VAT cut, subsidies for households and SMEs, LNG terminals, renewables, temporary nuclear extension, and targeted borrowing to curb inflation.

 

Key Points

A 200 billion euro package to cap energy costs, subsidize basics, and stabilize inflation for firms and households.

✅ Gas price brake and VAT cut reduce consumer and SME energy bills.

✅ Temporary electricity subsidies and nuclear extension aid winter supply.

✅ Funded via new borrowing; supports LNG and renewable expansion.

 

German Chancellor Olaf Scholz set out a 200 billion euro ($194 billion) "defensive shield", including a gas price brake and a cut in sales tax for the fuel, to protect companies and households from the impact of soaring energy prices in Germany.

Europe's biggest economy is trying to cope with surging gas and electricity costs, with local utilities seeking help, caused largely by a collapse in Russian gas supplies to Europe, which Moscow has blamed on Western sanctions following its invasion of Ukraine in February.

Germany agrees 200 bln euro package to shield against surging energy prices
By Holger Hansen and Kirsti Knolle

"Prices have to come down, so the government will do everything it can. To this end, we are setting up a large defensive shield," said Scholz.

Under the plans, to run until spring 2024, the government will introduce an emergency price brake on gas, the details of which will be announced next month, while Europe weighs emergency measures to limit electricity prices across the bloc. It is scrapping a planned gas levy meant to help firms struggling with high spot market prices. 

A temporary electricity price brake will subsidise basic consumption for consumers and small and medium-sized companies, and complements an electricity subsidy for industries under discussion. Sales tax on gas will fall to 7% from 19%.

In its efforts to cut its dependence on Russian energy, Germany is also promoting the expansion of renewable energy and developing liquefied gas terminals, but rolling back European electricity prices remains complex.

To help households and companies weather any winter supply disruption, amid rising heating and electricity costs this winter, especially in southern Germany, two nuclear plants previously due to close by the end of this year will be able to keep running until spring 2023.

The package will be financed with new borrowing this year, as Berlin makes use of the suspension of a constitutionally enshrined limit on new debt of 0.35% of gross domestic product.

Finance Minister Christian Lindner has said he wants to comply with the limit again next year, even as the EU outlines gas price cap strategies for the market.

Lindner, of the pro-business Free Democrats (FDP) who share power with Scholz's Social Democrats and the Greens, said on Thursday the country's public finances were stable.

"We can put it no other way: we find ourselves in an energy war," said Lindner. "We want to clearly separate crisis expenditure from our regular budget management, we want to send a very clear signal to the capital markets."

He also said the steps would act as a brake on inflation, which hit its highest level in more than a quarter of century in September.

Opposition conservative Markus Soeder, premier of the southern state of Bavaria, said the steps gave the right signal.

"It gives industry and citizens confidence that we can get through the winter," he said.

4 ways the energy crisis hits U.S. electricity, gas, EVs

U.S. Energy Crunch disrupts fuel and power markets, driving natural gas price spikes, coal resurgence, utility mix shifts, supply chain strains for EV batteries, and inflation pressures, complicating climate policy, OPEC outreach and LNG trade

 

Key Points

Supply-demand gaps raise fuel costs, revive coal, strain EV materials, and complicate U.S. climate policy and plans.

✅ Natural gas spikes shift generation from gas to coal

✅ Supply chain shortages hit nickel, silicon, and chips

✅ Policy tensions between price relief and decarbonization

 

A global energy crunch is creating pain for people struggling to fill their tanks and heat their homes, as well as roiling the utility industry’s plans to change its mix of generation and complicating the Biden administration’s plans to tackle climate change.

The ripple effects of a surge in natural gas prices include a spike in coal use and emissions that counter clean energy targets. High fossil fuel prices also are translating into high prices and a supply crunch for key minerals like silicon used in clean energy projects. On a call with investors yesterday, a Tesla Inc. executive said the company is having a hard time finding enough nickel for batteries.

The crisis could pose political problems for the Biden administration, which spent the last few months fending off criticism about rising fuel prices and inflation (Energywire, Oct. 14).

“Energy issues at this moment are as salient to the American public as they have been in quite some time,” said Christopher Borick, who directs the Muhlenberg College Institute of Public Opinion in Pennsylvania, where Biden stopped yesterday to pitch his infrastructure plan.

While gasoline prices have gotten headlines all summer, natural gas prices have risen faster than motor fuels, more than doubling from an average $1.92 per thousand cubic feet in September 2020 to $5.16 last month. By comparison, gasoline prices have risen about 55 percent in the last year, to $3.36 per gallon nationwide this week, according to AAA.

The roots of the problem go back to the beginning of the pandemic and the recession in 2020. Oil and gas prices fell so fast then that many producers, particularly in the U.S., simply stopped drilling.

Oil companies began predicting a few months later that the abrupt shutdown would eventually lead to shortages and price spikes when the economy recovered. Those predictions turned out to be accurate.

With the economy beginning to recover, demand for gas has gone up, but there’s not enough supply to go around.

While the U.S. energy crunch isn’t as severe as Europe’s energy crisis today, and analysts predict that gas prices will gradually fall next year, consumers could be in for a rough couple of months.

Here’s four ways the global energy crisis is impacting the United States, from the electricity sector to the political landscape:

What are the political repercussions?
For the Biden administration, the energy price hikes come amid fears of rising inflation and persistent supply bottlenecks at the nation’s ports as its climate ambitions face headwinds in Congress.

“The confluence of energy prices, logistical challenges and the need to move on climate have raised this to the top tier,” said Borick, who in the past has polled on energy and environmental issues in Pennsylvania.

Borick noted the administration is facing counterpressures: Even as it pushes to decarbonize the nation’s electric system, it wants to keep gas prices in check. High gasoline prices have been linked to declining political approval ratings, including for presidents, even if much of the price hikes are beyond their control.

White House press secretary Jen Psaki said earlier this month that the administration can take steps to address what it called “short-term supply issues,” but also needs to focus on the long term — and climate.

In hopes of capping prices, the White House has spoken with members of OPEC about increasing oil production — though OPEC has little control over natural gas prices. And earlier this month, the administration talked to U.S. oil and gas producers about helping to bring down prices.

That comes even as environmentalists have pushed Biden to ban federal fossil fuel leasing and drilling and stop new projects.

The moves to curb prices have prompted ridicule from Republicans, who have accused Biden of declaring war on U.S. energy by canceling the Keystone XL pipeline.

“The Biden administration won’t say it out loud, yet let’s admit it: There is a crisis,” Sen. John Barrasso (R-Wyo.) said this week on the Senate floor. “It is one that Joe Biden and his administration has created. It is a crisis of Joe Biden’s own making.”

The situation has also resurfaced comparisons to former President Carter, who struggled politically in the 1970s with gasoline shortages and other energy pressures. Some political scientists say, though, the comparison between the two isn’t apples to apples.

"In 1979, the crisis began with the Iranian Revolution, producing a supply shortage. In the USA, some states rationed the supply. That’s not occurring now. Oil prices were also regulated, another difference, “ said Terry Madonna, a senior fellow in residence for political affairs at Millersville University.

A Morning Consult poll released yesterday carried warning signs for Democrats with worries about the economy on the rise across the political spectrum.

Voters, however, were evenly split on how Biden is handling energy. Forty-two percent of respondents approve of Biden’s energy policy, compared with 45 percent who disapproved. The margin of error is 2 percentage points.

Will the electricity mix change?
Higher gas prices are giving coal a boost in some markets.

Atlanta-based Southern Co. told CNBC earlier this week, for instance, that coal was about 17 percent of the company’s power mix last year. That has changed in 2021.

“The unintended consequence of high gas prices is that coal becomes more economic, and so my sense is … our coal production has bumped up above 20 percent,” Southern CEO Tom Fanning said. “Now, how long that’ll persist, I don’t know.”

Fanning said “what we’re seeing right now, and the real challenge in America, is this notion of energy in transition.”

But the U.S. power sector has been evolving for years, with more renewables and less coal on the grid, and experts say the current energy crunch won’t change long-term utility trends in the industry.

“In general, I wouldn’t place too much emphasis on short-term fluctuations,” Jay Apt, a professor at Carnegie Mellon University, said in an email. “There is still a robust supply chain for most components needed for low-pollution power, including renewables.”

In fact, elevated fossil fuel prices, and high natural gas prices in particular, could accelerate the move toward wind, solar and batteries in some areas. That’s because power plants that run on coal and natural gas can be affected by rising and volatile fuel prices, as illustrated by the recent move in commodities globally. That means higher costs to run the facilities, even if power prices often climb along with gas prices.

“If I were a utility planner, this would cause me to double down on new generation from [wind] and solar and storage as opposed to building additional natural gas plants where, you know, I could be having these super high and volatile operating costs,” said Bri-Mathias Hodge, an associate professor in the Department of Electrical, Computer and Energy Engineering at the University of Colorado, Boulder.

Ed Hirs, an energy fellow at the University of Houston, said the current global situation doesn’t change the U.S. power sector’s overall move toward generation with lower operating costs.

For example, he said nuclear and coal plants can require hundreds of employees, and both have fuel costs. Hirs said a gas facility also needs fuel and may need dozens of employees. Wind and solar facilities often need a smaller number of workers and don’t require fuel in their operations, he noted.

“Eventually the cheap wins out,” Hirs said.

That isn’t even factoring in climate change — the reason world leaders are seeking to slash greenhouse gas emissions. Indeed, lowering emissions remains a priority among many states and big companies in the U.S.

Over the next 10 to 15 years, Hirs said, a key question will be whether battery technology can compete economically in terms of backing up renewables. He said a national carbon price, if enacted, would aid renewables and enhance returns on batteries.

“The real battle is going to be between natural gas and battery storage,” Hirs said.

Apt and M. Granger Morgan, who’s also a Carnegie Mellon professor, noted in a Hill piece last month that the U.S. gets about 40 percent of its power from carbon-free sources, including nuclear.

“Modelers and many power system operators agree that it is possible that renewables can cost-effectively make up roughly 80% of electricity generation,” the professors wrote, adding that other sources could include “storage and gas turbines powered with hydrogen, synfuels, or natural gas with carbon capture.”

What about EVs and renewables?
As for electric vehicles, executives with Tesla said on a call yesterday that supply-chain problems are the major brake on production for both vehicles and batteries.

Chief Financial Officer Zachary Kirkhorn said that the company’s factories aren’t running at full capacity because of an ongoing shortage of semiconductor chips. Customers are waiting longer for vehicles, he said, and wait lists are growing.

The challenges extend to raw materials. In batteries, Kirkhorn said, the company is having trouble finding enough nickel, and in vehicles, it is scrounging for aluminum. He said the problem is "not small," and that prices may rise as supply contracts come up for renewal.

The supply problems are creating "cost headwinds," he said, and so are rising labor costs. Tesla is not immune from the worker shortages that are plaguing the entire U.S. economy.

The production woes aren’t limited to Tesla: Automakers around the world have have had their output crimped by the chip shortage that accompanied the economic rebound after pandemic lockdowns. Unlike many other automakers, Tesla hasn’t been forced to pause its factory lines.

Tesla said it is poised to greatly expand its production of batteries for the electric grid — with a caveat.

Last month, Tesla broke ground on a new California factory to make Megapack, its 3 megawatt-per-hour lithium-ion batteries for use by power companies. That future factory’s capacity, 40 gigawatt per hour a year, is vastly more than the 3 GWh it made in the last calendar year.

However, today’s supply-chain problems are braking the making of both Megapack and Powerwall, Tesla’s battery for homes, Kirkhorn said. He added that production will increase "as soon as parts allow us."

Other advocates for EVs and renewable power expressed little concern about the supply crunch’s meaning for their industries, noting that higher prices alone don’t automatically trigger a broader green revolution on their own.

Those problems likely wouldn’t change the immediate course of the energy transition, researchers said.

"Short-term trends, week to week or even month to month, don’t matter much for investors or policy makers," wrote John Graham, a former budget official with the Bush administration and professor at Indiana University’s O’Neill School of Public and Environmental Affairs, in an email to E&E News.

The crunch may give policymakers a glimpse of the future, however, according to one minerals analyst.

"This isn’t going to be an outlier. I think increasingly you’re going to see pockets of the world start to feel these strains," said Andrew Miller, product director at Benchmark Mineral Intelligence, which focuses its research on battery minerals and battery supply chains.

The U.S. and its allies are only now beginning to develop their own supply chains for batteries and other key clean energy technologies, he noted. "The issue you’re facing, and this is one coming over time, is to have the platform in place. You have to have the supply chain of raw materials," he said.

"I think you’re going to see the most turbulence over the coming decade. … It’s not going to be a smooth transition,” added Miller.

How long will gas prices stay high?
The gap between natural gas demand and supply has led to severe price spikes in Europe, where utilities and other gas buyers have to compete against China for cargoes of liquefied natural gas, according to a research note from IHS Markit Ltd.

Here in the U.S., the causes are the same, but the results aren’t as extreme. Less than 10 percent of domestic gas production is exported as LNG, so American customers don’t have to compete as much against overseas buyers.

Instead, gas-hungry sectors of the economy have run into another problem, IHS analyst Matthew Palmer said in an interview. Gas producers have been cautious about increasing their output, largely because of pressure from investors to limit their spending.

“That theme has really put a governor on production,” he said.

The disconnect will likely mean higher home gas bills and higher electric prices this winter, although deep freeze events or warm weather could disrupt the trend, he said. The U.S. Energy Information Administration is predicting that average heating bills for homes that use gas furnaces will rise 30 percent this winter.

This comes as U.S. gas supply remains high, according to a biennial assessment from the Potential Gas Committee, a group of volunteer geoscientists, engineers and other experts.

Including reserves, future gas supply in the U.S. stands at a record 3,863 trillion cubic feet, up 25 tcf from levels reported in 2019, the group said Tuesday at an event co-hosted with the American Gas Association.

Of that total, so-called technically recoverable resources — or those in the ground but not yet recovered — are 3,368 tcf, the PGC said, down less than 0.2 percent from the last assessment.

The amount of technically recoverable gas went relatively unchanged from year-end 2018 for several reasons, including a lack of company activity in exploration efforts last year due to COVID, said Alexei Milkov, the group’s executive director.

Another factor is that basins mature and shale plays “cannot increase in resources forever,” said Milkov, also a professor of geology and geological engineering at the Colorado School of Mines.

Still, Milkov added, “We cannot tell you right now if we are on a new plateau, or if we are going to start seeing more growth in gas resources again, right, because it’s a complex issue.”

The EIA predicts that gas production will increase and prices will begin to drop in 2022.

David Flaherty, CEO of the Republican polling firm Magellan Strategies in Colorado, said prices could particularly hit seniors. But he said he expected the energy crunch to ease in the U.S. well before the election.

“By early summer, this is likely to be behind us,” he said.

Renewable growth drives common goals for electricity networks across the globe

Energy Transition Grid Reforms address transmission capacity, interconnection, congestion management, and flexibility markets, enabling renewable integration and grid stability while optimizing network charges and access in Australia, Ireland, and Great Britain.

 

Key Points

Measures to expand transmission, boost flexibility, and manage congestion for reliable, low-carbon electricity systems.

✅ Transmission upgrades and interconnectors ease congestion

✅ Flexible markets, DER, and storage bolster grid stability

✅ Evolving network charges and access incentivize siting

 

Electricity networks globally are experiencing significant increases in the volume of renewable capacity as countries seek to decarbonise their power sectors, even as clean energy's 'dirty secret' highlights integration trade-offs, without impacting the security of supply. The scale of this change is creating new challenges for power networks and those responsible for keeping the lights on.

The latest insight paper from Cornwall Insight – Market design amidst global energy transition – looks into this issue. It examines the outlook for transmission networks, and how legacy design and policies are supporting decarbonisation, aligning with IRENA findings on renewables and shaping the system. The paper focuses on three key markets; Australia, Ireland and Great Britain (GB).

Australia's main priority is to enhance transmission capacity and network efficiency; as concerns over excess solar risking blackouts grow in distribution networks, without this, the transmission system will be a barrier to growth for decentralised flexibility and renewables. In contrast, GB and Ireland benefit from interconnection with other national markets. This provides them with additional levers that can be pulled to manage system security and supply. However, they are still trying to hone and optimise network flexibility in light of steepening decarbonisation objectives.

Unsurprisingly, renewable energy resources have been growing in all three markets, with Ireland regarded as a leader in grid integration, with this expected to continue for the foreseeable future. Many of these projects are often located in places where network infrastructure is not as well developed, creating pressure on system operation as a result.

In all three markets, unit charges are rising, driven by a reduced charging base as decentralised energy grows quickly. This combination of changes is leading to network congestion, a challenge mirrored by the US grid overhaul for renewables underway, as transmission network development struggles to keep up, and flexibility markets are being optimised and changed.

In summary, reforms are on-going in each jurisdiction to accommodate the rapid physical transformation of the generation mix. Each has its objectives and tensions which are reflective of wider global reform programmes being undertaken in most developed, liberalised and decarbonising energy markets.

Gareth Miller, CEO of Cornwall Insight, said: “Despite differences in market design and characteristics, all three markets are grappling with similar issues, that comes from committing to deep decarbonisation. This includes the most appropriate methods for charging for networks, managing access to them and dealing with issues such as network congestion and constraint.

“In all three countries, renewable projects are often placed in isolated locations, as seen in Scotland where more pylons are needed to keep the lights on, away from the traditional infrastructure that is closer to demand. However, as renewable growth is set to continue, the networks will need to transition from being demand-centric to more supply orientated.

“Both system operators and stakeholders will need to continually evaluate their market structures and designs to alleviate issues surrounding locational congestion and grid stability. Each market is at very different stages in the process in trying to improve any problems implementing solutions to allow for higher efficiencies in renewable energy integration.

“It is uncertain whether any of the proposed changes will fundamentally resolve the issues that come with increased renewables on the system. However, despite marked differences, they certainly could all learn from each other and elements of their network arrangements, as well as from US decarbonisation strategies research.”

Disrupting Electricity? This Startup Is Digitizing Our Very Analog Electrical System

Solid-State AC Switching reimagines electrification with silicon-based, firmware-driven controls, smart outlets, programmable circuit breakers, AC-DC conversion, and embedded sensors for IoT, energy monitoring, surge protection, and safer, globally compatible devices.

 

Key Points

Solid-state AC switching replaces mechanical switches with silicon chips for intelligent, programmable power control.

✅ Programmable breakers trip faster and add surge and GFCI protection

✅ Shrinks AC-DC conversion, boosting efficiency and device longevity

✅ Enables sensor-rich, IoT-ready outlets with energy monitoring

 

Electricity is a paradox. On the one hand, it powers our most modern clean cars and miracles of computing like your phone and laptop. On the other hand, it’s one of the least updated, despite efforts to build a smarter electricity infrastructure nationwide, and most ready-for-disruption parts of our homes, offices, and factories.

A startup in Silicon Valley plans to change all that, in California’s energy transition where reliability is top of mind, and has just signed deals with leading global electronics manufacturers to make it happen.

“The end point of the electrification infrastructure of every building out there right now is based on old technology,” Thar Casey, CEO of Amber Solutions, told me recently on the TechFirst podcast. “Basically some was invented ... last century and some came in a little bit later on in the fifties and sixties.”

Ultimately, it’s an almost 18th century part of modern homes.

Even smart homes, with add-ons like the Tesla Powerwall, still rely on legacy switching.

The fuses, breakers, light switches, and electrical outlets in your home are ancient technology that would easily understood by Thomas Edison, who was born in 1847. When you flip a switch and instantly flood your room with light, it feels like a modern right. But you are simply pushing a piece of plastic which physically moves one wire to touch another wire. That completes a circuit, electricity flows, and ... let there be light.

Casey wants to change all that. To transform our hard-wired electrical worlds and make them, in a sense, soft wired. And the addressable market is literally tens of billions of devices.

The core innovation is a transition to solid-state switches.

“Take your table, which is a solid piece of wood,” Casey says. “If you can mimic what an electromechanical switch does, opening and closing, inside that table without any actual moving parts, that means you are now solid state AC switching.”

And solid-state is exactly what Silicon Valley is all about.

“Solid state it means it can be silicon,” Casey says. “It can be a chip, it can be smaller, it can be intelligent, you can have firmware, you can add software ... now you have a mini computer.”

That’s a significant innovation with a huge number of implications. It means that the AC to DC converters attached to every appliance you plug into the wall — the big “bricks” that are part of your power cord, for instance — can now be a tiny fraction of the size. Appliance run on DC, direct current, and the electricity in your walls is AC, alternating current; similar principles underpin advanced smart inverters in solar systems, and it needs to be converted before it’s usable, and that chunk of hardware, with electrolytics, magnetics, transformers and more, can now be replaced, saving space in thermostats, CO2 sensors, coffee machines, hair dryers, smoke detectors ... any small electric device.

(Since those components generally fail before the device does, replacing them is a double win.)

Going solid state also means that you can have dynamic input range: 45 volts all the way up to 600 volts.

So you can standardize one component across many different electric devices, and it’ll work in the U.S., it’ll work in Europe, it’ll work in Japan, and it will work whether it’s getting 100 or 120 or 220 volts.

Building it small and building it solid state has other benefits as well, Casey says, including a much better circuit breaker for power spikes as the U.S. grid faces climate change impacts today.

“This circuit breaker is programmable, it has intelligence, it has WiFi, it has Bluetooth, it has energy monitoring metering, it has surge protection, it has GFCI, and here’s the best part: we trip 3000 times faster than a mechanical circuit breaker.”

What that means is much more ambient intelligence that can be applied all throughout your home. Rather than one CO2 sensor in one location, every power outlet is now a CO2 sensor that can feed virtual power plant programs, too. And a particulate matter sensor and temperature sensor and dampness sensor and ... you name it.

Amber’s next-generation system-on-chip complete replacement for smart outlets
Amber’s next-generation system-on-chip complete replacement for smart outlets JOHN KOETSIER
“We put as many as fifteen functions ... in one single gang box in a wall,” Casey told me.

Solid state is the gift that keeps giving, because now every outlet can be surge-protected. Every outlet can have GFCI — ground fault circuit interruption — not just the ones in your bathroom. And every outlet and light switch in your home can participate in the sensor network that powers your home security system. Oh, and, if you want, Alexa or Siri or the Google Assistant too. Plus energy-efficient dimmers for all lighting appliances that don’t buzz.

So when can you buy Amber switches and outlets?

In a sense, never.

Casey says Amber isn’t trying to be a consumer-facing company and won’t bring these innovations to market themselves. This July, Amber announced a letter of intent with a global manufacturer that includes revenue, plus MOUs with six other major electronics manufacturers. Letters of intent can be a dime a dozen, as can memoranda of understanding, but attaching revenue makes it more serious and significant.

The company has only raised $6.7 million, according to Craft, and has a number of competitors, such as Blixt, which has funding from the European Union, and Atom Power, which is already shipping technology. But since Amber is not trying to be a consumer product and take its innovations to market itself, it needs much less cash to build a brand and a market. You’ll be able to buy Amber’s technology at some point; just not under the Amber name.

“We have over 25 companies that we’re in discussions with,” Casey says. “We’re going to give them a complete solution and back them up and support them toward success. Their success will be our success at the end of the day.”

Ultimately, of course, cost will be a big part of the discussion.

There are literally tens of billions of switches and outlets on the planet, and modernizing all of them won’t happen overnight. And if it’s expensive, it won’t happen quickly either, even as California turns to grid-scale batteries to ease strain.

Casey is a big cagey with costs — there are still a lot of variables, after all. But it seems it won’t cost that much more than current technology.

“This can’t be $1.50 to manufacture, at least not right now, maybe down the road,” he told me. “We’re very competitive, we feel very good. We’re talking to these partners. They recognize that what we’re bringing, it’s a cost that is cost effective.”

End of an Era: UK's Last Coal Power Station Goes Offline

UK Coal-Free Energy Transition highlights the West Burton A closure, accelerating renewable energy, wind, solar, nuclear, energy storage, smart grid upgrades, decarbonization, and net-zero goals while ensuring reliability, affordability, and a just transition for workers.

 

Key Points

A nationwide shift from coal power to renewables, storage, and nuclear to meet net-zero while maintaining reliability.

✅ West Burton A closure ends UK coal-fired generation

✅ Wind, solar, nuclear, storage strengthen grid resilience

✅ Government backs a just transition and worker retraining

 

The United Kingdom marks a historic turning point in its energy transition with the closure of the West Burton A Power Station in Nottinghamshire. This coal-fired power plant, once a symbol of the nation's industrial might, has now delivered its final watts of electricity to the grid, signalling the end of coal power generation in the UK.


A Landmark Shift Towards Clean Energy

The closure of West Burton A reflects a dramatic shift in the UK's energy landscape. Coal, the backbone of the UK's power generation for decades, is being phased out in favour of renewable energy sources like wind, solar, and nuclear. This transition aligns with the UK's ambitious net-zero emissions target, which aims to radically decarbonize the country's economy by 2050, though progress can falter, as when low-carbon generation stalled in 2019 amid changing market conditions.


Changing Energy Landscape

In the past, coal-fired power plants provided reliable, on-demand power. However, growing awareness of their significant environmental impact, particularly their contribution to climate change,  has accelerated the move away from coal. The UK government has set clear targets for eliminating coal power generation, and the industry has seen a steady decline as the share of coal fell to record lows in the electricity system.


Renewables Fill the Gap

The remarkable growth of renewable energy sources has enabled the transition away from coal. Wind and solar power, in particular, have experienced rapid development and falling costs, and in 2016 wind generated more electricity than coal for the first time. The UK now boasts substantial offshore and onshore wind farms and extensive solar installations. Additionally, investments in nuclear power and emerging energy storage technologies are increasing the reliability and diversity of the UK's power grid.


Economic and Social Impacts

The closure of the last coal-fired power station carries both economic and social impacts. While this change represents a victory for environmentalists, marked by milestones like a full week without coal power in Britain, the end of coal mining and power generation will lead to job losses in communities traditionally reliant on these industries.  The government has committed to supporting affected regions and facilitating a "just transition" for workers by retraining and creating new opportunities in the clean energy sector.


Global Implications

The UK's commitment to a coal-free future serves as a powerful example for other nations seeking to decarbonize their energy systems, including peers where Alberta's last coal plant closed recently. The nation's experience demonstrates that a transition to renewable energy sources is both possible and necessary. However, it also highlights the importance of careful planning and addressing the social and economic impacts of such a rapid energy revolution.


The Road Ahead

While the closure of West Burton A Power Station marks a historic milestone, the UK's transition to clean energy is far from complete. Maintaining a reliable and affordable energy supply, even as coal-free power records raise questions about energy bills, will require continued investment in renewable energy sources, energy storage, and advanced grid technologies.

Is 5G a waste of electricity? Experts say it's complicated

5G Energy Costs highlight base station power consumption, carrier electricity bills, and carbon emissions in China, while advances in energy efficiency, sleep modes, and cooling systems aim to optimize low-latency networks and reduce operational expenses.

 

Key Points

5G energy costs rise with power-hungry base stations, yet per-bit efficiency and sleep modes help cut bills.

✅ 5G base stations use ~4x 4G electricity

✅ Per-bit 5G energy efficiency is ~4x better than 4G

✅ Sleep modes and advanced cooling reduce OPEX and emissions

 

As 5G developers look desperately for a "killer app" to prove the usefulness of the superfast wireless technology, mobile carriers in China are complaining about the high energy cost of 5G signal towers.

And the situation is, according to experts, more complicated than many have thought.

The costly 5G

5G technology can be 10 or more times faster than 4G and significantly more responsive to users' input, but the speed comes at a cost.

A 5G base station consumes "four times more electricity" than its 4G counterpart, said Ding Haiyu, head of wireless and terminals at the China Mobile Research Institute, during a symposium on 5G and carbon neutrality in Beijing, a key focus for countries pursuing a net-zero grid by 2050 worldwide.

But concerning each bit of data transmitted, 5G is four times more energy-efficient than 4G, according to Ding.

This means that mobile carriers should fully occupy their 5G network for as long time as possible, but that can be hard at this moment, as many people are still holding 4G smartphones.

"When the 5G stations are running without people using them, they are really electricity guzzlers," said Zhu Qingfeng, head of power supply design at China Information Technology Designing and Consulting Institute Co., Ltd., who represents China Unicom at the symposium. "Each of the three telecom carrier giants are emitting about ten million tonnes of carbon in the air."

"We have to shut down some 5G base stations at night to reduce emission," he added.

Some utilities are testing fuel cell solutions to keep backup batteries charged much longer, supporting network resilience at lower emissions.

A representative from China Telecom said electricity bills of the nationwide carrier reached a new high of 100 billion yuan (about $15 billion) a year, mirroring the power challenges for utilities as data center demand booms elsewhere.

Getting better

While admitting the excessive cost of 5G, experts at the symposium also agreed that the situation is improving, even as climate pressures on the grid continue to mount.

Ding listed a series of recent technologies that is helping reduce the energy use of 5G, including chips of better process, automatic sleeping and wake-up of base stations and liquid nitrogen-based cooling system, and superconducting cables as part of ongoing upgrades.

"We are aiming at halving the 5G electricity cost to only two times of 4G in two years," Ding said.

Experts also discussed the possibility of making use of 5G's low latency features to help monitoring the electricity grid, thus making the digital grid smarter and more cost effective.

G's energy cost is seen as a hot topic for the incoming World 5G Convention in Beijing in early August, alongside smart grid transformation themes. Stay tuned to CGTN Digital as we bring you the latest news about the convention and 5G technology.
