New twist on classic material could advance quantum computing
Researchers at Penn State University have developed a novel approach to enhance the electro-optic properties of barium titanate, a classic material known since 1941 for its strong ability to convert electrical signals into optical signals. By reshaping barium titanate into ultrathin strained thin films, the team achieved over a tenfold improvement in the conversion efficiency of electrons to photons at room temperature compared to previous results at cryogenic temperatures. This breakthrough addresses a long-standing challenge, as barium titanate had not been widely commercialized due to fabrication difficulties and stability issues, with lithium niobate dominating the electro-optic device market instead. The improved material has significant implications for quantum computing and data center energy efficiency. Quantum technologies often require cryogenic conditions, but transmitting quantum information over long distances needs room-temperature optical links, which this advancement could enable. Additionally, data centers, which consume vast amounts of energy primarily for cooling, could benefit from integrated photonic technologies that use photons rather than electrons to transmit data

The article from CleanTechnica highlights the critical but often overlooked role of refrigerants in the efficiency, cost, and environmental impact of HVAC systems, including air conditioners and heat pumps. Refrigerants are essential chemical compounds that enable cooling and heating functions, yet many systems operate with improper refrigerant levels. A common issue is undercharging, where systems have less refrigerant than designed, sometimes by about 15 percent, which can occur even at installation due to improper adjustment for specific configurations like longer piping. This undercharging leads to reduced cooling performance and increased energy consumption. Over time, refrigerant leaks caused by aging equipment, corrosion, and vibrations further degrade system efficiency. Residential HVAC systems can lose 5–11 percent of their refrigerant annually, resulting in a significant drop in the coefficient of performance (COP). Even a 10 percent refrigerant loss can reduce system efficiency noticeably, increasing energy bills by $72–$144 during summer months. Larger losses above 20 percent cause steep performance declines and soaring

The article from CleanTechnica examines the limitations of molten salt as a medium for industrial heat storage, despite its historical prominence and technical appeal. Molten salt, typically a mixture of sodium and potassium nitrate, has been used since the 1980s in concentrated solar power plants due to its high heat capacity, density, and wide liquid temperature range. Large-scale projects like Crescent Dunes in Nevada and Noor III in Morocco demonstrated molten salt's ability to store and dispatch solar heat, with Gemasolar in Spain achieving continuous 24-hour operation. This track record established molten salt as a credible technology for dispatchable solar electricity and industrial heat storage. However, the article highlights several critical drawbacks that limit molten salt's future role. The fundamental issue is its low round-trip efficiency for electricity storage, typically only 40-45%, due to significant losses when converting stored heat back into electricity via steam Rankine or advanced turbine cycles. This efficiency is far below that of lithium-ion batteries (over 85%)

The US National Science Foundation (NSF) has awarded a $2 million grant to a Lehigh University-led team to develop resilient materials for rotating detonation engines (RDEs), a new propulsion technology that promises higher power, improved fuel efficiency, and lower emissions compared to conventional rocket and jet engines. RDEs generate thrust by sustaining a supersonic detonation wave inside a ring-shaped chamber, releasing significantly more energy than traditional combustion methods. This could enable more compact, efficient engines capable of delivering satellites to precise orbits at lower cost and fuel consumption. A major challenge preventing RDEs from advancing beyond laboratory prototypes is the extreme temperatures and pressures generated by the detonation wave, which rapidly degrade existing engine materials. Current metal components fail after only a few engine cycles under these punishing conditions. The Lehigh-led team, collaborating with Carnegie Mellon University, University of California Irvine, the Air Force Research Laboratory, and industry partners, aims to overcome this by developing high-performance copper-based alloys.

The article from CleanTechnica highlights the inherent inefficiency and wastefulness of fossil fuel energy use, particularly in transportation and industrial processes. It points out that typical gasoline-powered cars are only about 15% efficient, meaning the vast majority of the energy paid for is lost as heat rather than used to move the vehicle. This inefficiency is not a minor leak but a systemic issue embedded in the fossil fuel economy, which continuously wastes huge amounts of energy to sustain its profit-driven extraction and consumption cycle. The article critiques the fossil fuel industry's narrative that fossil fuels are indispensable for modern life and economic progress, emphasizing that much of the energy consumed is wasted rather than productively used. The piece draws on insights from economist Robert Ayres and energy analyst Lloyd Alter to argue that the economy fundamentally transforms energy into goods, services, and waste heat, with fossil fuel systems being particularly wasteful. It challenges the common belief that transitioning to renewable energy is impossible due to high energy demands, citing data from the Liverm

The article discusses an initiative by the Malawian-UK NGO Tiyeni to improve crop yields in Malawi through climate-smart agriculture, specifically a technique called Deep Bed Farming (DBF). This method involves breaking up a compacted soil layer known as "hardpan," which restricts root growth, water infiltration, and air penetration, thereby limiting crop productivity. By disrupting this hardpan layer, farmers can more than double their crop yields in the first year. Traditionally, breaking the hardpan is labor-intensive, requiring manual hoeing. To ease this process, a small electric tractor powered by solar energy has been introduced and tested in Malawi. This tractor, which functions similarly to a rototiller, can break up the hardpan with significantly less physical effort than manual labor. The electric tractor is charged using solar panels connected to a nearby microgrid, leveraging Malawi’s abundant sunlight. This approach is more economical and environmentally friendly compared to diesel-powered machinery, as Malawi imports all its petroleum products, which are

A breakthrough at the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) promises to expand the use of friction stir welding (FSW) in manufacturing, particularly on automotive assembly lines. FSW is an energy-efficient welding technique that uses a spinning tool to generate heat and deformation, joining metals without rivets or adhesives. However, its adoption has been limited because the process exerts tremendous force—up to 5,000 pounds—that traditionally requires a rigid anvil underneath the materials to constrain and ensure precise welds. This constraint has made it difficult to apply FSW broadly on assembly lines. PNNL researchers have developed a novel “self-fixturing” friction stir welding system that integrates both the spinning tool and a miniature backing plate into a robotic arm attachment. This innovation eliminates the need for a separate rigid anvil, allowing the welding tool to be more maneuverable and adaptable to complex parts. The team is also incorporating a hydraulic system that captures the forces generated during welding,

Verdagy Hydrogen, a California-based company, has developed a reengineered alkaline water electrolyzer platform called “Dynamic AWE” that significantly improves hydrogen production efficiency beyond conventional systems. By adapting chlor-alkali chemistry and employing a unique single-cell architecture that virtually eliminates shunt currents—electrical losses common in traditional alkaline stacks—Verdagy claims to have surpassed US Department of Energy (DOE) efficiency targets years ahead of schedule. The company validated its efficiency gains through rigorous benchmarking, normalizing performance data to atmospheric pressure and accounting for compression power, enabling fair comparisons across different electrolyzer designs. The efficiency improvements translate directly into substantial economic benefits. For example, a 1 kWh/kg efficiency gain at an electricity price of $50/MWh results in savings of $0.50 per kilogram of hydrogen produced. At scale, such as a 100-megawatt plant, this could amount to $3.65 million in annual savings. While this alone may not fully close the cost gap with

A new air-conditioning system called the Energy Storing and Efficient Air Conditioner (ESEAC), co-developed by the National Renewable Energy Laboratory (NREL) and Blue Frontier Inc., promises to significantly reduce cooling costs and electricity demand on the grid. Tested in a Florida trial, the 20-ton ESEAC unit demonstrated the ability to cut peak air-conditioning power demand by over 90% and reduce cooling bills by approximately 45%. The system achieves these savings by integrating energy storage with cooling and humidity control, shifting the most energy-intensive parts of the cooling process to off-peak hours or times when renewable energy is abundant. ESEAC operates by decoupling dehumidification from cooling, using a liquid desiccant to absorb moisture from incoming air and then applying ultra-efficient indirect evaporative cooling. This approach contrasts with conventional vapor-compression air conditioners that cool and dehumidify simultaneously, often leading to inefficiencies.

The article highlights an innovative benefit of heat pump water heaters (HPWHs): they provide free, filtered cool air as a byproduct of heating water. Unlike traditional water heaters that emit pollution, HPWHs extract heat from the surrounding air to warm water, exhausting only cool air similar to an air conditioner. This process makes them highly efficient, delivering about four units of heat for every unit of energy consumed, resulting in low electricity costs (typically $100-$150 annually). The author has installed multiple HPWHs and, after initially ducting the cool air outside, recently began exhausting it indoors, effectively using the system as a free air conditioner during hot summer days. By increasing the water temperature setting from 120°F to 140°F during peak solar production hours, the HPWH runs its heat pump for several hours, producing cooling equivalent to a small window AC unit without additional electricity costs. This strategy cools the living space during the hottest part of the day, with built-in anti-scald

Researchers at Texas A&M University, led by Dr. Patrick Shamberger, are advancing "ice battery" technology to improve energy efficiency in heating and cooling large buildings. Ice batteries store thermal energy by freezing water or similar materials at night when electricity demand and costs are low, then release the stored cold during the day to cool buildings. This approach reduces daytime electricity demand, easing stress on the power grid and lowering consumer costs. However, current systems require significant nighttime power and their efficiency heavily depends on the materials used, which must be stable, reversible, and durable over decades. The research focuses on optimizing materials such as salt hydrates—salts containing water molecules in their crystal structures—that can absorb and release thermal energy effectively. By tailoring these materials to operate at temperatures compatible with advanced HVAC and heat pump systems, the ice batteries can better integrate with building energy needs and support flexible energy use. A key challenge is preventing phase segregation, where materials separate into different phases during cycling, which degrades performance.

The article "Body, not brain: Why humanoid robots still fail outside the lab" argues that despite advances in AI and impressive demonstrations by humanoid robots like Boston Dynamics’ Atlas and Tesla’s Optimus, fundamental limitations in robot body design prevent these machines from performing robustly in real-world environments. Experts highlight that current robots have rigid, inflexible bodies with limited joints and sensor capabilities, which restrict their ability to move naturally and adapt to complex, unpredictable terrain. This results in high energy consumption, frequent breakdowns, and limited endurance compared to humans, who benefit from mechanically intelligent bodies that passively assist movement and adaptation. Hamed Rajabi, director of the Mechanical Intelligence Research Group, critiques the prevailing “brain-first” approach that relies heavily on software to compensate for mechanical shortcomings.

The article discusses how traditional coffee roasting techniques contribute significantly to the coffee industry’s carbon footprint, accounting for up to 15% of its total emissions. Conventional roasting methods, largely unchanged since the early 1900s, rely on fossil fuels and involve heating roasters to around 600°C in batch processes that are energy-inefficient and environmentally harmful. This outdated approach not only increases greenhouse gas emissions but also leads to higher operational costs and growing pressure from consumers demanding sustainable products. To address these challenges, Belgium-based company CEE has developed an innovative continuous roasting system using Siemens’ Digital Twin technology and software tools such as Solid Edge, Simcenter, and NX. This new method moves coffee beans along a conveyor through precision-controlled chambers, using hot air at less than half the temperature of traditional roasters and recirculating it multiple times. The result is a roasting process that uses two to three times less energy, enabling easier electrification and the potential for fully renewable or hybrid energy use. Siemens

A research team at Chiba University, led by Professor Hiroo Sekiya, has developed a machine learning-based design method for wireless power transfer (WPT) systems that maintain stable output regardless of load changes, a property known as load-independent (LI) operation. Traditional WPT systems require precise component values based on idealized equations, but real-world factors like parasitic capacitance and manufacturing tolerances often cause unstable output voltage and loss of zero voltage switching (ZVS), which reduces efficiency. The new approach models the WPT circuit with differential equations incorporating real component behaviors and uses a genetic algorithm to optimize circuit parameters for stable voltage, high efficiency, and low harmonic distortion. Testing their method on a class-EF WPT system, the researchers achieved voltage fluctuations under 5% across varying loads, significantly better than the 18% typical in conventional systems.

The article discusses the potential and challenges of integrating artificial intelligence (AI) into electric vehicles (EVs), particularly focusing on improving battery efficiency and longevity. AI can enhance the accuracy of the State of Charge (SOC) measurement, a critical metric indicating the remaining battery capacity that ensures safety by preventing overcharging or depletion. However, the adoption of AI in EV battery management has been slow due to safety concerns, as AI systems are often seen as "black boxes" with unclear causality, making it difficult to verify and assign liability in case of failures. Recent advances show promise in using AI to capture complex battery aging patterns and optimize performance more effectively than traditional methods. Yet, testing reveals that even minor sensor faults can cause AI to produce dangerously inaccurate SOC readings, risking sudden shutdowns or battery fires. To address this, researchers propose a “safety cage” system—a rigorously tested monitoring layer that supervises AI outputs by cross-checking simple physical parameters like voltage and temperature.

Chinese scientists from the Lanzhou Institute of Chemical Physics, led by Professors Zhang Junyan and Gong Zhenbin, have experimentally observed quantum friction in folded graphene for the first time. By precisely folding graphene layers to create controlled curvature and internal strain, they altered electron behavior at the nanoscale. This strain forced electrons into fixed energy states called pseudo-Landau levels, reducing energy loss as heat and resulting in a nonlinear, sometimes decreasing friction pattern as the number of graphene layers increased. Their findings challenge classical friction models and provide the first direct evidence of quantum friction occurring between two solid surfaces. The research, conducted at ultra-low temperatures using a carefully engineered graphene system, opens new avenues for understanding friction at the atomic scale. The team plans to investigate whether similar quantum friction effects occur in other materials and under more practical conditions. Ultimately, this work could lead to technologies that better manage or minimize energy loss in nanoscale electronics and quantum computing devices by exploiting quantum friction phenomena. The study was published in Nature Communications

The article discusses BrainChip’s Akida processor, a neuromorphic AI chip inspired by the brain’s energy-efficient event-driven processing. Unlike traditional AI chips that process every data frame regardless of changes, Akida leverages spiking neural networks to compute only when input signals exceed a threshold, significantly reducing redundant calculations. This approach exploits data sparsity by processing only changes between frames, leading to power savings of up to 100 times in scenarios with minimal activity, such as a static security camera feed. However, in highly dynamic scenes with frequent changes, these savings diminish. Akida’s architecture uses a digital implementation of spiking neural networks, employing activation functions like ReLU to trigger computations selectively. This mimics biological neurons that fire only when stimulated beyond a threshold, enabling progressively fewer computations across network layers. Despite these efficiency gains, neuromorphic chips like Akida remain niche due to limitations such as 8-bit precision constraints and gaps in development tooling.

Researchers at the Hong Kong University of Science and Technology (HKUST) have developed a groundbreaking photocatalytic system using manganese-doped CdS/ZnS quantum dots (QDs) that can break strong chemical bonds with 99% less energy than traditional methods. By harnessing a quantum effect known as the two-photon spin-exchange Auger process, these QDs efficiently generate "hot electrons"—high-energy electrons capable of driving challenging reactions previously thought too difficult for light-based catalysis. This approach allows two low-energy photons to combine their energy inside a quantum dot, producing a powerful electron that can cleave tough bonds such as C–Cl, C–Br, C–I, C–O, C–C, and N–S, and perform reductions on molecules with extremely negative potentials (down to −3.4 V vs. SCE). The system notably enables reactions like the Birch reduction, traditionally requiring harsh conditions like liquid ammonia and alkali metals, to proceed under

Researchers at Fuzhou University in China have developed a novel machine vision sensor that adapts to extreme lighting conditions about five times faster than the human eye, achieving adaptation in roughly 40 seconds. This sensor uses quantum dots—nano-sized semiconductors that efficiently convert light into electrical signals—engineered to trap and release electric charges in a manner analogous to how human eyes store light-sensitive pigments to adjust to darkness. The device’s layered structure, incorporating lead sulfide quantum dots with polymer and zinc oxide, enables rapid and energy-efficient adaptation to harsh light changes, mimicking key behaviors of human vision. Beyond speed, the sensor improves energy efficiency by filtering visual data at the source, reducing the computational load typical of conventional machine vision systems that process all data indiscriminately. This selective preprocessing is similar to the human retina’s function of focusing on relevant visual information, which could benefit applications like autonomous vehicles and robots operating in variable lighting environments. The research team plans to expand the technology by integrating larger sensor arrays

Researchers at Finland’s Aalto University have developed an innovative wafer-thin “cloud” metasurface coating that can dynamically switch between bright white and deep grey states, enabling surfaces to either cool by reflecting sunlight or heat by absorbing it, all while remaining nearly invisible to infrared (thermal) cameras. This dual-function coating mimics the behavior of cumulus clouds, adapting its optical properties to manage heat passively and without energy input. Unlike traditional white paints that cool by scattering sunlight but become conspicuous in thermal imaging, or black surfaces that absorb heat but emit strong infrared signals, this metasurface maintains very low mid-infrared emissivity (8–13 microns), effectively camouflaging heat signatures in both modes. The coating’s unique performance arises from a disordered array of metallic nanostructures that manipulate light through multiple scattering and “polarizonic reflection.” In the white state, solar photons are reflected back into space, providing radiative cooling under full sun, while in the grey state,

According to the U.S. Energy Information Administration’s (EIA) Annual Energy Outlook 2025 (AEO2025) Reference case, electricity consumption for commercial computing in the U.S. is projected to grow rapidly, increasing from about 8% of commercial sector electricity use in 2024 to 20% by 2050. This growth is expected to outpace improvements in computing energy efficiency and surpass electricity use for other major commercial end uses such as lighting, space cooling, and ventilation. The rise in computing demand is significant enough to reverse the previous trend of declining commercial electricity intensity (measured in kWh per square foot). The growth in commercial computing energy use is driven largely by data centers, which are far more energy intensive than general computing devices like desktops and laptops. By 2050, data centers could require additional energy for up to 7% of all U.S. commercial floorspace, spanning many building types including healthcare and large offices.

Scientists at National Yang Ming Chiao Tung University in Taiwan have developed a new type of perovskite solar cell (PeSC) that achieves a remarkable 38.7% power conversion efficiency (PCE) under low indoor lighting conditions of around 2,000 lux, typical of office environments. While traditional silicon solar cells perform better under direct sunlight (up to 26% PCE), these perovskite cells excel in dimmer settings, producing energy even on cloudy days or indoors. The PeSCs are thin, lightweight, flexible, and semi-transparent, offering advantages over rigid and heavy silicon panels, which are limited to flat, durable surfaces. The researchers enhanced the solar cells by adjusting the bandgap through molecular composition changes in the perovskite layers, enabling efficient absorption of indoor light—a capability not achievable with silicon cells. This breakthrough suggests potential applications for powering small devices in indoor or low-light environments, reducing reliance on traditional power sources and expanding solar technology use beyond outdoor

Researchers at KAIST have developed an advanced smart window technology called RECM (Reversible Electrodeposition and Electrochromic Mirror) that significantly enhances energy efficiency and urban comfort. Unlike traditional windows that passively respond to light and temperature, the RECM smart window actively controls the transmission of visible light and near-infrared radiation through electrical signals. This technology addresses major issues such as heat gain through glass surfaces, which contributes to substantial energy loss in buildings, and urban glare caused by reflected light, improving both indoor climate control and pedestrian visual comfort. The RECM window operates in three modes: a transparent mode allowing sunlight and heat to warm interiors during cold periods; a deep blue tinted mode that absorbs light and heat for privacy and temperature regulation; and a reflective mode where a silver coating reflects sunlight and heat while reducing glare for pedestrians. Testing with a miniature model house demonstrated that the RECM window could reduce indoor temperatures by approximately 81°F (27.2°C) compared to conventional glass, highlighting its

LNG Canada, a large liquefied natural gas facility in Kitimat, British Columbia, is nearing full operation and represents a significant development in Canada's energy and climate landscape. The project, led by Shell with international partners, aims to export 14 million tons of LNG annually, sourced from British Columbia’s Montney Formation and transported via the 670-kilometer Coastal GasLink pipeline. While LNG Canada incorporates efficiency measures such as using hydroelectric power for part of its liquefaction energy and employing high-efficiency turbines, the overall LNG supply chain remains energy-intensive and emits substantial greenhouse gases. The facility primarily serves Asian markets, with shorter shipping routes compared to U.S. Gulf Coast LNG exports, which somewhat reduces transit emissions.

The article from CleanTechnica highlights the ongoing political battle over clean energy and electric vehicle (EV) tax credits in the United States. It underscores that Republican politicians, historically funded by the fossil fuel industry, have consistently opposed legislation promoting clean energy, energy efficiency, and EV incentives despite growing evidence of environmental harm caused by fossil fuels. While Democrats enacted significant clean energy tax credits through the Inflation Reduction Act of 2022 when they controlled the federal government, the current Republican majority in the White House, House, and Senate is moving to repeal or drastically reduce these incentives. Recent developments indicate that the Senate Republicans are poised to phase out clean energy and energy efficiency tax credits, albeit at a slower pace than the House’s more aggressive budget bill. However, EV incentives face rapid and severe cuts. Critics, including the Natural Resources Defense Council and Senator Ron Wyden, warn that these actions will lead to higher energy prices, job losses in manufacturing, factory closures, and exacerbate the climate crisis.

Researchers have developed a novel quantum clock design that significantly reduces energy waste while maintaining high precision in timekeeping. Traditional quantum clocks measure time by counting discrete, irreversible events, each generating entropy and requiring energy, leading to a direct trade-off between precision and energy consumption. The new approach abandons this model by allowing quantum excitations to evolve coherently and uninterrupted across a system, tracking the overall flow of time rather than individual ticks. This method, based on coherent quantum transport, avoids repeated measurements that produce entropy, thereby breaking the previously assumed linear relationship between precision and entropy production. The innovative clock operates on principles drawn from quantum many-body systems, where particles exhibit coordinated, wave-like behavior, enabling precise control with minimal thermodynamic cost. By trading off precision with resolution—similar to waiting for a larger quantity of sand to fall in an hourglass rather than counting individual grains—the clock achieves greater accuracy without proportionally increasing entropy. Theoretical models validate this concept, and experimental efforts, such as those underway at Ch

Engineers at the University of California, San Diego have developed a groundbreaking passive cooling technology for data centers that sets a new record by handling over 800 watts per square centimeter of heat dissipation. This fiber-based cooling system uses a specially engineered membrane with interconnected pores that passively removes heat through evaporation, eliminating the need for energy-intensive fans, compressors, or pumps. Unlike traditional cooling methods, this approach leverages capillary action to wick liquid across the membrane surface, where evaporation naturally draws heat away from electronic chips, offering a quieter and more energy-efficient alternative. The innovation addresses longstanding challenges in adapting evaporative cooling to the extreme thermal loads of modern AI data centers, where conventional porous membranes either clogged or caused unstable boiling. By optimizing pore size and reinforcing the membrane mechanically, the UCSD team achieved stable, high-performance cooling over multiple hours. While the technology currently operates below its theoretical maximum, efforts are underway to integrate it into cold plates for direct processor cooling and to commercialize the solution through a startup

The innovation addresses a critical challenge in transportation—lightweighting—which can significantly improve energy efficiency, battery performance, and range in electric vehicles, drones, and spacecraft. The motor was successfully tested by powering a scale model car on asphalt roads, achieving speeds over half a meter per second and continuous operation for 60 minutes under varying loads. A key breakthrough enabling this development was a novel purification technique called the LAST (Lyotropic Liquid Crystal-Assisted Surface Texturing) process. This method removes metal catalyst impurities embedded in CNTs during production, reducing contamination from 12.7% to less than 0.8%, while preserving the nanotubes’ electrical properties. The process involves dissolving CNTs in chlorosulfonic acid to form a liquid crystal state that self-aligns the tubes; exposure to water then generates hydrochloric acid that eliminates iron impurities. The purified CNT cables achieved an electrical conductivity of 7.7 megasiemens per meter, comparable to copper but at a fraction of the weight (1.7 g/cm³ vs. copper’s 8.9 g/cm³). This advancement holds promise for significantly reducing motor weight across various applications without compromising performance.

Researchers led by the University of Vienna have demonstrated that a small-scale photonic quantum processor can outperform classical AI algorithms in machine learning classification tasks, marking a rare real-world example of quantum advantage with current hardware. Using a quantum photonic circuit developed at Italy’s Politecnico di Milano and a machine learning algorithm from UK-based Quantinuum, the team showed that the quantum system made fewer errors than classical counterparts. This experiment is one of the first to demonstrate practical quantum enhancement beyond simulations, highlighting specific scenarios where quantum computing provides tangible benefits. In addition to improved accuracy, the photonic quantum processor exhibited significantly lower energy consumption compared to traditional hardware, leveraging light-based information processing. This energy efficiency is particularly important as AI’s growing computational demands raise sustainability concerns. The findings suggest that even today’s limited quantum devices can enhance machine learning performance and energy efficiency, potentially guiding a future where quantum and classical AI technologies coexist symbiotically to push technological boundaries and promote greener, faster, and smarter AI solutions.

The Chinese electric vehicle (EV) market has been embroiled in a prolonged and intense price war over the past several years, causing significant tension among major automakers. Geely chairman Li Shufu criticized the ongoing "cutthroat price competition," calling it a "race to the bottom" and advocating instead for competition based on technology, quality, service, brand, and ethics. Great Wall Motor has been particularly vocal against BYD, accusing the latter of unfair pricing tactics and reporting BYD to Chinese regulators over alleged emissions standard violations related to two of BYD’s popular hybrid models. Great Wall claims these models used non-pressurized fuel tanks, leading to quicker fuel evaporation, and Geely has publicly supported Great Wall’s stance. In response to the escalating price war and regulatory concerns, China’s Ministry of Industry and Information Technology (MIIT) reportedly intervened by convening a special meeting with automakers to call for an end to the price battles. The ongoing conflict has also triggered a selloff in Chinese automaker stocks, reflecting market unease. The article raises the question of how much of the price decline in the Chinese EV sector is due to aggressive price cutting versus natural cost reductions driven by technological innovation, economies of scale, and industry maturation. While Geely and Great Wall see the price war as harmful and artificial, BYD argues that its competitive pricing stems from faster innovation and better consumer responsiveness. The situation remains fluid, with industry watchers awaiting further developments.
