More than a century into its existence, Philips is once again betting heavily on semiconductors. This time the consumer electronics firm is looking to harness their potential as a source of light.

The producer of one in four of the world's lights, which sold its semiconductor business in 2006 after it was undercut by Asian rivals, has invested more than 4 billion euros (US $5.47 billion) to ride the clean-tech wave and defend its world-leading position.

But this time, Philips is better prepared for competition.

The company is betting on a shift in the lighting market, away from inefficient incandescent light bulbs and toward light-emitting diodes or LEDs — perhaps best known for their use in the flashing indicators found on most consumer devices.

"In terms of value around 2015, LED will be bigger than conventional light sources," said Philips executive Niels Haverkorn. In the fourth quarter of 2009, LED-based products made up more than 10 percent of Philips' lighting sales for the first time.

Made of diodes, or chips, the first practical LED was a red light developed in 1962. Now the technology has advanced to enable them to produce light colors across the color spectrum.

To help draw attention to LEDs' potential to scale up, come down in price and reduce carbon dioxide emissions, Philips at the turn of the year converted the famous numerals on the Times Square Ball — which is raised and lowered to signify the coming of a new year — to LED technology.

Other stunts have included a display of LED lights at the world heritage-listed windmills at Kinderdijk in the Netherlands and a solar-powered LED streetlamp at the Copenhagen climate talks.

LEDs' advantages include long life, energy efficiency and the fact they do not contain mercury, as opposed to compact fluorescent lamps (CFLs), which after they became commercial in the 1980s were the first alternative to conventional bulbs.

Philips estimates LEDs made up just 6-8 percent of the 45-50 billion euros in global lighting sales in 2009. The company, which had about 6.5 billion euros in annual lighting sales in 2009, expects the global lighting market to grow to more than 80 billion euros by 2015.

To some extent, it is banking on regulation. The European Union — which is phasing out old-style incandescent bulbs ahead of a total ban in 2012 — sees LEDs as a crucial step in reducing carbon dioxide emissions, because they use up to 80 percent less energy and last much longer.

About 16 billion conventional light bulb fixtures globally have to be replaced in the coming decades with LED lights. Researchers at consultancy iSuppli expect the LED market to continue to grow despite the economic crisis, estimating that in 2013 sales from LEDs globally will be around $15 billion.

Although lighting is seen as a crucial driver of Philips' future earnings growth, analysts see it as more of a long-term rather than short-term support for Philips' stock.

"The lighting market is set to shift both in terms of light source and applications. Philips is trying to ride this curve and, in our view, has all the right ingredients in place if the industry were indeed to move in this direction," said Jan Hein de Vroe, technology analyst at ING, who has a "buy" recommendation on the stock.

Of 37 analysts tracking Philips shares, 19 have a "strong buy" or "buy" rating, while 14 have a "hold" and 4 a "sell" or "strong sell" recommendation, according to StarMine data.

Analysts also warn competition in the market will be brutal. Philips' main rivals in the sector are Siemens' Osram, General Electric, Sharp, Samsung, and Cree of the United States.

Anticipating this — and building on lessons it learnt from sliding semiconductor prices — the 119-year old company is scaling up its LED output. Where before it used to sell just light bulbs, in LEDs the offer is a packaged "solution," such as a luminaire, or the lamp and fitting combined.

"The manufacturing technique is quite similar to that seen in semiconductor manufacturing, where foundries compete mainly on price," said De Vroe. "In that sense we think it is wise on the part of Philips to move their focus toward 'solutions'."

Philips sold a majority in its semiconductors business to a private equity consortium in 2006, retaining a minority interest in the company, renamed NXP. But it remains committed to lighting: in the business since 1891, it's a veteran of illumination.

But even if the company has a savvier strategy in approaching the modern LED market, the challenges it faces include current high prices which are deterring some retailers from stocking the products.

The quality of LED that can deliver a light that feels "warm" — a type that only large companies like Philips are currently able to produce — is very expensive.

It now costs about $46 to deliver 1,000 lumens — a measure of the power of light — or units of "warm" light, compared with $25 for the "cold" light variety.

By 2015, the cost of "warm" LED lights is expected to slide to $4 per 1,000 lumens versus $2 for "cold" lights, according to estimates from the U.S. Department of Energy. To produce incandescent globes, it said, currently costs $0.29 per 1,000 lumens.

It expects the cost of producing LEDs to fall below that of compact fluorescent lamps in about 2013, but still be more expensive than an incandescent bulb.

Business users are enthusiastic, said Yvan Dejaeghere, director at wholesaler Technische Unie, a subsidiary of French electronics equipment distributor Sonepar.

"In our business-to-business professional segment we are seeing huge demand for new applications and new fixtures," Dejaeghere said. The cost of replacing one conventional globe with an LED could be earned back within two years, he said.

LEDs are most frequently being used to replace conventional bulbs in restaurants and hotel lobbies, where they can take on a decorative effect due to their ability to change colors. Factories have yet to switch due to the high cost.

Philips' business clients include the Marriott hotel chain and Heineken, which uses LED lighting in its Amsterdam brewery shop. Vodafone is also a client, while supermarkets Sainsbury and Tesco use LEDs in their refrigeration displays.

For consumers, it's not so simple. The array of choices in lighting outlets can be dazzling: LEDs, conventional bulbs, fluorescent tubes or halogen lights?

Ralf Buehler, vice president for Europe and Middle East and Africa at LED lighting specialist Cree, said it may still take a while before LEDs will be available to all customers.

"We are five to six years away from a situation where you would go to one of the large do-it-yourself stores where they have lots and lots of these products at a commercially viable price in stock," he said.

Gert Spaargaren, a professor in the Environmental Policy Group at Wageningen University in the Netherlands, said lighting retailers are proving slow to embrace the new technology.

"What is needed is that retailers... embrace the new products, integrate them into their mainstream assortment," he said. "Consumers show a really high willingness to go along with sustainable alternatives if they are offered in an appropriate way by appropriate providers."

Berlin urged to remove barriers to PV

Germany Solar Cap Removal would accelerate photovoltaics, storage, and renewables, replacing coal and nuclear during phaseout with 10GW per year toward 162GW by 2030, boosting grid resilience, O&M jobs, and domestic clean energy growth.

 

Key Points

A policy change to scrap the 52GW limit, enabling 10GW/year PV and storage to replace coal and nuclear capacity.

✅ Scrap 52GW cap to prevent post-2020 market slump

✅ Add 10GW PV annually; scale residential, commercial, grid storage

✅ Create jobs in planning, installation, and O&M through 2030

 

The German Solar Association (BSW) has called on the government to remove barriers to the development of new solar power capacity in Germany and storage capacity needed to replace coal and nuclear generation that is being phased out.

A 52GW cap should be scrapped, otherwise there is a risk that a market slump will occur in the solar industry after 2020, BSW said, especially as U.S. solar expansion plans signal accelerating global demand.

BSW managing director Carsten Körnig said: “Time is running out, and further delays are irresponsible. The 52GW mark will already be reached within a few months.”
A new report from BSW, in cooperation with Bonn-based marketing and social research company EuPD Research and The smarter E Europe initiative, said 10GW a year is needed as well as an increase in battery storage capacity.

This would lead to cumulative photovoltaic capacity of 162GW and 15GW residential, commercial and grid storage systems by 2030, in line with global renewable records being set, leading to new job opportunities.

The number of jobs in the domestic photovoltaic and storage industries could increase to 78,000 by the end of the next decade from today’s level of 26,400, aligning with forecasts of wind and solar reaching 50% by mid-century, said 'The Energy Transition in the Context of the Nuclear and Coal Phaseout – Perspectives in the Electricity Market to 2040' study.

Job growth would take place for the most part in the fields of planning, installation and operations and maintenance of PV systems, as solar uptake in Poland increases, the report said.

In maintenance alone, employment would increase from 9,200 to 26,000, with additional opened up by tapping into the market potential of medium- to long-term storage systems, alongside changing electricity prices in Northern Europe that favor flexibility, it said.

The report added that industry revenue could grow from €5bn to €12.5bn in the coming decade.

The report was supported by BayWa Re E3/DC, Fronius, Goldbeck Solar, IBC Solar, Panasonic, Sharp, Siemens, Sonnen, Suntech, Tesvolt and Varta.

Carbon emissions fall as electricity producers move away from coal

Global Electricity Emissions Decline highlights a 2% drop as coal power falls, while wind and solar surge. EU and US decarbonize faster; China expands coal and gas, challenging Paris Agreement climate targets.

 

Key Points

A 2% annual fall in power-sector CO2, led by less coal and rising wind and solar in the EU and US.

✅ Coal generation fell 3% globally despite China growth

✅ EU and US cut coal; wind and solar up 15% worldwide

✅ Gas gains in US; rapid renewables rollout needed for targets

 

Carbon emissions from the global electricity system fell by 2% last year, the biggest drop in almost 30 years, as countries began to turn their backs on coal-fired power plants.

A new report on the world’s electricity generation revealed the steepest cut in carbon emissions since 1990, with IEA data indicating global totals flatlined in 2019 as the US and the EU turned to cleaner energy sources.

Overall, power from coal plants fell by 3% last year, even as China’s reliance on coal plants climbed for another year to make up half the world’s coal generation for the first time.

Coal generation in the US and Europe has halved since 2007, and last year collapsed by almost a quarter in the EU and by 16% in the US.

The report from climate thinktank Ember, formerly Sandbag, warned that the dent in the world’s coal-fired electricity generation relied on many one-off factors, including milder winters across many countries.

“Progress is being made on reducing coal generation, but nothing like with the urgency needed to limit climate change,” the report said.

Dave Jones, the lead author of the report, said governments must dramatically accelerate the global energy transition so that global coal generation collapses throughout the 2020s.

“To switch from coal into gas is just swapping one fossil fuel for another. The cheapest and quickest way to end coal generation is through a rapid rollout of carbon-free electricity such as wind and solar,” he said.

“But without concerted policymaker efforts to boost wind and solar, we will fail to meet climate targets. China’s growth in coal, and to some extent gas, is alarming but the answers are all there.”

The EU has made the fastest progress towards replacing coal with wind and solar power, while the US has increased its reliance on gas as Wall Street’s energy strategy shifted following its shale boom in recent years.

The report revealed that renewable wind and solar power rose by 15% in 2019 to make up 8% of the world’s electricity.

In the EU, wind and solar power made up almost a fifth of the electricity generated last year, and Europe’s oil majors are turning electric as the bloc stayed ahead of the US which relied on these renewable sources for 11% of its electricity. In China and India, renewable energy made up 8% and 9% of the electricity system, respectively.

To meet the Paris climate goals, the world needs to record a compound growth rate of 15% for wind and solar generation every year – which will require “a colossal effort”, the report warned.

The electricity generation report was published as a separate piece of research claimed that 38 out of 75 of the world’s largest asset managers are stalling on taking action on environmental, social and governance (ESG) issues, and amid investor pressure on utilities to release climate reports.

The latest ranking by Asset Owners Disclosure Project, a scheme managed by the investment campaign group ShareAction, found that the 38 asset managers have weak or nonexistent policy commitments and fail to account for their real-world impacts across their mainstream assets.

The survey also claimed that the investment managers often lack appropriate engagement and escalation processes on climate change, human rights and biodiversity.

Scores were based on a survey of activities in responsible investment governance, climate change, human rights, and biodiversity and ranged between AAA to E. Not a single asset manager was granted an AAA or AA rating, the top two scores available.

Felix Nagrawala, ShareAction analyst, said: “While many in the industry are eager to promote their ESG credentials, our analysis clearly indicates that few of the world’s largest asset managers can lay claim to having a truly sustainable approach across all their investments.”

ShareAction said the world’s six largest asset managers – including BlackRock (rated D), State Street (D) and Vanguard (E) – were among the worst performers.

Vanguard said it was committed to companies making “appropriate disclosures on governance, strategy and performance on relevant ESG risks”. BlackRock and State Street did not respond to a request for comment.

The nuclear power dispute driving a wedge between France and Germany

Franco-German Nuclear Power Divide shapes EU energy policy, electricity market reform, and decarbonization strategies, as Paris backs reactors and state subsidies while Berlin prioritizes renewables, hydrogen, and energy security after Russian gas shocks.

 

Key Points

A policy rift over nuclear shaping EU market reform, subsidies, and the balance between reactors and renewables.

✅ Nuclear in EU targets vs. renewables-first strategy

✅ Market design disputes over long-term power prices

✅ Energy security after Russian gas; hydrogen definitions

 

Near the French village of Fessenheim, facing Germany across the Rhine, a nuclear power station stands dormant. The German protesters that once demanded the site’s closure have decamped, in a sign of Europe's nuclear decline, and the last watts were produced three years ago. 

But disagreements over how the plant from 1977 should be repurposed persist, speaking to a much deeper divide over nuclear power, which Eon chief's warning to Germany underscored, between the two countries on either side of the river’s banks.

German officials have disputed a proposal to turn it into a centre to treat metals exposed to low levels of radioactivity, Fessenheim’s mayor Claude Brender says. “They are not on board with anything that might in some way make the nuclear industry more acceptable,” he adds.

France and Germany’s split over nuclear power is a tale of diverging mindsets fashioned over decades, including since the Chernobyl disaster in USSR-era Ukraine. But it has now become a major faultline in a touchy relationship between Europe’s two biggest economies.

Their stand-off over how to treat nuclear in a series of EU reforms has consequences for how Europe plans to advance towards cleaner energy. It will also affect how the bloc secures power supplies as the region weans itself off Russian gas, even though nuclear would do little for the gas issue, and how it provides its industry with affordable energy to compete with the US and China. 

“There can be squabbles between partners. But we’re not in a retirement home today squabbling over trivial matters. Europe is in a serious situation,” says Eric-André Martin, a specialist in Franco-German relations at French think-tank IFRI. 

France, which produces two-thirds of its power from nuclear plants and has plans for more reactors, is fighting for the low-carbon technology to be factored into its targets for reducing emissions and for leeway to use state subsidies to fund the sector.

For Germany, which closed its last nuclear plants this year and, having turned its back on nuclear, has been particularly shaken by its former reliance on Russian gas, there’s concern that a nuclear drive will detract from renewable energy advances.

But there is also an economic subtext in a region still reeling from an energy crisis last year, reviving arguments for a needed nuclear option for climate in Germany, when prices spiked and laid bare how vulnerable households and manufacturers could become.

Berlin is wary that Paris would benefit more than its neighbours if it ends up being able to guarantee low power prices from its large nuclear output as a result of new EU rules on electricity markets, amid talk of a possible U-turn on the phaseout, people close to talks between the two countries say.

Ministers on both sides have acknowledged there is a problem. “The conflict is painful. It’s painful for the two governments as well as for our [EU] partners,” Sven Giegold, state secretary at the German economy and climate action ministry, where debates about whether a nuclear resurgence is possible persist, tells the Financial Times. 

Agnès Pannier-Runacher, France’s energy minister, says she wants to “get out of the realm of the emotional and move past the considerable misunderstandings that have accumulated in this discussion”.

In a joint appearance in Hamburg last week, German chancellor Olaf Scholz and French president Emmanuel Macron made encouraging noises over their ability to break the latest deadlock: a disagreement over the design of the EU’s electricity market. Ministers had been due to agree a plan in June but will now meet on October 17 to discuss the reform, aimed at stabilising long-term prices.

But the French and German impasse on nuclear has already slowed down debates on key EU policies such as rules on renewable energy and how hydrogen should be produced. Smaller member states are becoming impatient. The delay on the market design is “a big Franco-German show of incompetence again”, says an energy ministry official from another EU country who requested anonymity.

Is The Global Energy Transition On Track?

Global Decarbonization Strategies align renewable energy, electrification, clean air policies, IMO sulfur cap, LNG fuels, and the EU 2050 roadmap to cut carbon intensity and meet Paris Agreement targets via EVs and efficiency.

 

Key Points

Frameworks that cut emissions via renewables, EVs, efficiency, cleaner marine fuels, and EU policy roadmaps.

✅ Renewables scale as wind and solar outcompete new coal and gas.

✅ Electrification of transport grows as EV costs fall and charging expands.

✅ IMO 2020 sulfur cap and LNG shift cut shipping emissions and particulates.

 

Are we doing enough to save the planet? Silly question. The latest prognosis from the United Nations’ Intergovernmental Panel on Climate Change made for gloomy reading. Fundamental to the Paris Agreement is the target of keeping global average temperatures from rising beyond 2°C. The UN argues that radical measures are needed, and investment incentives for clean electricity are seen as critical by many leaders to accelerate progress to meet that target.

Renewable power and electrification of transport are the pillars of decarbonization. It’s well underway in renewables - the collapse in costs make wind and solar generation competitive with new build coal and gas.

Renewables’ share of the global power market will triple by 2040 from its current level of 6% according to our forecasts.

The consumption side is slower, awaiting technological breakthrough and informed by efforts in countries such as New Zealand’s electricity transition to replace fossil fuels with electricity. The lower battery costs needed for electric vehicles (EVs) to compete head on and displace internal combustion engine (ICE)  cars are some years away. These forces only start to have a significant impact on global carbon intensity in the 2030s. Our forecasts fall well short of the 2°C target, as does the IEA’s base case scenario.

Yet we can’t just wait for new technology to come to the rescue. There are encouraging signs that society sees the need to deal with a deteriorating environment. Three areas of focus came out in discussion during Wood Mackenzie’s London Energy Forum - unrelated, different in scope and scale, each pointing the way forward.

First, clean air in cities.  China has shown how to clean up a local environment quickly. The government reacted to poor air quality in Beijing and other major cities by closing older coal power plants and forcing energy intensive industry and the residential sector to shift away from coal. The country’s return on investment will include a substantial future health care dividend.

European cities are introducing restrictions on diesel cars to improve air quality. London’s 2017 “toxicity charge” is a precursor of an Ultra-Low Emission Zone in 2019, and aligns with UK net-zero policy changes that affect transport planning, to be extended across much of the city by 2020. Paris wants to ban diesel cars from the city centre by 2025 and ICE vehicles by 2030. Barcelona, Madrid, Hamburg and Stuttgart are hatching similar plans.

 

College Promise In California: Community-Wide Efforts To Support Student Success

Second, desulphurisation of global shipping. High sulphur fuel oil (HSFO) meets around 3.5 million barrels per day (b/d) of the total marine market of 5 million b/d. A maximum of 3.5% sulphur content is allowed currently. The International Maritime Organisation (IMO) implements a 0.5% limit on all shipping in 2020, dramatically reducing the release of sulphur oxides into the atmosphere.

Some ships will switch to very low sulphur fuel oil, of which only around 1.4 million b/d will be available in 2020. Others will have to choose between investing in scrubbers or buying premium-priced low sulphur marine gas oil.

Longer-term, lower carbon-intensity gas is a winner as liquefied natural gas becomes fuel of choice for many newbuilds. Marine LNG demand climbs from near zero to 50 million tonnes per annum (tpa) by 2040 on our forecasts, behind only China, India and Japan as a demand centre. LNG will displace over 1 million b/d of oil demand in shipping by 2040.

Third, Europe’s radical decarbonisation plans. Already in the vanguard of emissions reductions policy, the European Commission is proposing to reduce carbon emissions for new cars and vans by 30% by 2030 versus 2020. The targets come with incentives for car manufacturers linked to the uptake of EVs.

The 2050 roadmap, presently at the concept stage, envisages a far more demanding regime, with EU electricity plans for 2050 implying a much larger power system. The mooted 80% reduction in emissions compared with 1990 will embrace all sectors. Power and transport are already moving in this direction, but the legacy fuel mix in many other sectors will be disrupted, too.

Near zero-energy buildings and homes might be possible with energy efficiency improvements, renewables and heat pumps. Electrification, recycling and bioenergy could reduce fossil fuel use in energy intensive sectors like steel and aluminium, and Europe’s oil majors going electric illustrates how incumbents are adapting. Some sectors will cite the risk decarbonisation poses to Europe’s global competitiveness. If change is to come, industry will need to build new partnerships with society to meet these targets.

The 2050 roadmap signals the ambition and will be game changing for Europe if it is adopted. It would provide a template for a global roll out that would go a long way toward meeting UN’s concerns.

Consumer choice has suddenly revolutionized the electricity business in California. But utilities are striking back

California Community Choice Aggregators are reshaping electricity markets with renewable energy, solar and wind sourcing, competitive rates, and customer choice, challenging PG&E, SDG&E, and Southern California Edison while advancing California's clean power goals.

 

Key Points

Local governments that buy power, often cleaner and cheaper, while utilities handle delivery and billing.

✅ Offer higher renewable mix than utilities at competitive rates

✅ Utilities retain transmission and billing responsibilities

✅ Rapid expansion threatens IOU market share across California

 

Nearly 2 million electricity customers in California may not know it, but they’re part of a revolution. That many residents and businesses are getting their power not from traditional utilities, but via new government-affiliated entities known as community choice aggregators. The CCAs promise to deliver electricity more from renewable sources, such as solar and wind, even as California exports its energy policies across Western states, and for a lower price than the big utilities charge.

The customers may not be fully aware they’re served by a CCA because they’re still billed by their local utility. But with more than 1.8 million accounts now served by the new system and more being added every month, the changes in the state’s energy system already are massive.

Faced for the first time with real competition, the state’s big three utilities have suddenly become havens of innovation. They’re offering customers flexible options on the portion of their power coming from renewable energy, amid a broader review to revamp electricity rates aimed at cleaning the grid, and they’re on pace to increase the share of power they get from solar and wind power to the point where they are 10 years ahead of their deadline in meeting a state mandate.

#google#

But that may not stem the flight of customers. Some estimates project that by late this year, more than 3 million customers will be served by 20 CCAs, and that over a longer period, Pacific Gas & Electric, Southern California Edison, and San Diego Gas & Electric could lose 80% of their customers to the new providers.

Two big customer bases are currently in play: In Los Angeles and Ventura counties, a recently launched CCA called the Clean Power Alliance is hoping by the end of 2019 to serve nearly 1 million customers. Unincorporated portions of both counties and 29 municipalities have agreed in principle to join up.

Meanwhile, the city of San Diego is weighing two options to meet its goal of 100% clean power by 2035, as exit fees are being revised by the utilities commission: a plan to be submitted by SDG&E, or the creation of a CCA. A vote by the City Council is expected by the end of this year. A city CCA would cover 1.4 million San Diegans, accounting for half SDG&E’s customer demand, according to Cody Hooven, the city’s chief sustainability officer.

Don’t expect the big companies to give up their customers without a fight. Indeed, battle lines already are being drawn at the state Public Utilities Commission, where a recent CPUC ruling sided with a community energy program over SDG&E, and local communities.

“SDG&E is in an all-out campaign to prevent choice from happening, so that they maintain their monopoly,” says Nicole Capretz, who wrote San Diego’s climate action plan as a city employee and now serves as executive director of the Climate Action Campaign, which supports creation of the CCA.

California is one of seven states that have legalized the CCA concept, even as regulators weigh whether the state needs more power plants to ensure reliability. (The others are New York, New Jersey, Massachusetts, Ohio, Illinois and Rhode Island.) But the scale of its experiment is likely to be the largest in the country, because of the state’s size and the ambition of its clean-power goal, which is for 50% of its electricity to be generated from renewable sources by 2030.

California created its system via legislative action in 2002. Assembly Bill 117 enabled municipalities and regional governments to establish CCAs anywhere that municipal power agencies weren’t already operating. Electric customers in the CCA zones were automatically signed up, though they could opt out and stay with their existing power provider. The big utilities would retain responsibility for transmission and distribution lines.

The first CCA, Marin Clean Energy, began operating in 2010 and now serves 470,000 customers in Marin and three nearby counties.

The new entities were destined to come into conflict with the state’s three big investor-owned utilities. Their market share already has fallen to about 70%, from 78% as recently as 2010, and it seems destined to keep falling. In part that’s because the CCAs have so far held their promise: They’ve been delivering relatively clean power and charging less.

The high point of the utilities’ hostility to CCAs was the Proposition 16 campaign in 2009. The ballot measure was dubbed the “Taxpayers Right to Vote Act,” but was transparently an effort to smother CCAs in the cradle. PG&E drafted the measure, got it on the ballot, and contributed all of the $46.5 million spent in the unsuccessful campaign to pass it.

As recently as last year, PG&E and SDG&E were lobbying in the legislature for a bill that would place a moratorium on CCAs. The effort failed, and hasn’t been revived this year.

Rhetoric similar to that used by PG&E against Marin’s venture has surfaced in San Diego, where a local group dubbed “Clear the Air” is fighting the CCA concept by suggesting that it could be financially risky for local taxpayers and questioning whether it will be successful in providing cleaner electricity. Whether Clear the Air is truly independent of SDG&E’s parent, Sempra Energy, is questionable, as at least two of its co-chairs are veteran lobbyists for the company.

SDG&E spokeswoman Helen Gao says the utility supports “customers’ right to choose an energy provider that best meets their needs” and expects to maintain a “cooperative relationship” with any provider chosen by the city.

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.
