Cooling smarter: reducing building electricity use

As summers get hotter, AC demand climbs, but researchers are pursuing a mix of strategies—blocking heat entry with smart windows and shading, reflective roofs, and passive cooling materials; improving efficiency with desiccant-based cooling, built-in storage to ease peak load, and smarter ventilation—tailored to climate and building type. No single fix fits all, but reducing peak demand can lessen the need for new power generation while keeping people cool and safe.

Newsom Defends California’s Low-Res Tire Rules Amid Price Backlash

California Gov. Gavin Newsom defended the state’s controversial tire rules, arguing that mandating lower-resistance, energy-efficient tires will save drivers money and reduce fuel use, with the California Energy Commission estimating nearly $1 billion in annual savings in fuel and electricity; the policy could affect about 70% of replacement tires, drawing opposition from Goodyear and some Republicans who warn higher costs, while other manufacturers voiced caution on enforcement and affordability.

Liquid cooling could curb data centers' water hunger

Rising AI workloads are driving a boom in data centers that currently rely on water-intensive cooling. Air cooling is energy-inefficient and its evaporative methods strain water supplies; liquid cooling—especially direct-to-chip systems—could dramatically cut both water use and electricity, with potential for heat reuse and rainwater harvesting. Adoption faces retrofit costs and safety concerns, so a gradual shift toward liquid cooling and smarter water management may offer the best path to reducing the sector’s environmental footprint.

California to phase out less efficient replacement tires

California to phase out less efficient replacement tires

California’s Energy Commission approved a two-phase rule to curb replacement tires with higher rolling resistance. Beginning in 2029, tires must meet a maximum rolling resistance of 9.1 N/kN, then drop to 7.2 N/kN in 2033, ensuring sold replacements are as energy-efficient as original equipment. Regulators estimate phase 1 could save about $79 in four months and phase 2 about $153 in seven months, while tire makers warn costs could rise and a large share of current tires could be banned. Enforcement will involve a lab testing program and retailer checks, with numerous exclusions (e.g., competition, winter, used/treaded, space-saver, and some off-road tires).

Dell's XPS 13 Delivers Surprising Power Efficiency Against Apple Silicon

Jeff Geerling’s comparison pits the MacBook Neo against Dell’s XPS 13 in a Linpack-style efficiency test: the MacBook hits 57.0 GFLOPS at 10.6W (5.38 GFLOPS/W), while the Dell posts 127.9 GFLOPS at 20.6W (6.21 GFLOPS/W); Dell also scores for Linux support and a backlit keyboard, with idle energy use similar to the MacBook. The takeaway: modern x86 hardware can rival ARM in energy efficiency, depending on workload.

Europe Chooses Cooling: Heat Waves Drive Air Conditioning from Niche to Necessity

Record heat across Western Europe is pushing air conditioners from a luxury into a growing necessity, with European brands reporting double‑digit sales gains in markets like Italy, Spain, France, and the UK. Market observers say the trend is structural, driven by rising temperatures, aging housing, and public health concerns, even as Europe’s AC penetration remains far lower than the U.S. (about 1 in 5 households vs ~9 in 10 in the U.S.).

Sun-powered Vermont retreat on 52 acres blends privacy with mountain views

A solar-powered home on 52.6 acres in Tunbridge, Vermont, designed for energy efficiency and privacy, is on the market for $595,000. The property features elm kitchen countertops, a wide glass slider with mountain views, a primary bedroom with a barn-door wardrobe, a vintage clawfoot tub in the bath, and an on-site studio that mirrors the home’s design near the historic Cilley Covered Bridge.

Turning Heat Fluctuations Into Computation: The Promise of Thermodynamic Machines

Thermodynamic computing seeks to harness ambient thermal noise and energy flow as a computational resource, using either equilibrium dynamics or driven nonequilibrium trajectories to solve problems with far less energy and heat than conventional digital hardware. Early silicon-based prototypes and startup efforts show potential for tasks like matrix inversion and generative AI workloads, offering a path that could complement or compete with quantum approaches and providing new insights into how information processing occurs in biology.

Starlink's V5 Dish Drops Weight, Cuts Power—Speed Stays Flat

Starlink unveiled the V5 satellite dish, a smaller, lighter (2.4 lb) and more power-efficient unit than the V4 (75–100W down to 35–50W), but with a slightly lower max speed (375+ Mbps vs 400+ Mbps). The V5 excludes a new router and will be bundled with the Router Mini; it includes a roof pipe adapter and is available now in select US residential areas as production expands. Pricing isn't announced, and the V5 may co-exist with the V4 across plans while Starlink eyes broader deployment.

MIT advances photonic links to petabit-speed data transfer

MIT's FUTUR-IC program unveils advances in electronically-photonic integration to push data transmission toward and beyond one petabit per second with lower energy use, including evanescent and GRIN optical couplers plus a third previously developed one—optical 'solder bumps' linking photonic devices. These approaches can be manufactured with existing semiconductor equipment, and Earthster models environmental impact while the initiative trains a workforce for semiconductor efficiency. The aim is to separate computation (electronics) from communication (photonic) to reduce data-center energy as AI and cloud services scale.

Trump push to loosen home-appliance efficiency standards faces backlash

The Energy Department proposes weakening or pausing future efficiency updates for home appliances (air conditioners, refrigerators, washing machines), arguing it preserves consumer choice and lowers costs, but critics warn it would increase energy use and strain the grid, undo decades of efficiency gains, and could face lawsuits from Democratic-led states; the move mirrors earlier Trump-era efforts and follows other rollbacks since he returned to office.

EU dodges pro/con on home air conditioning amid blistering heatwave

Amid a brutal heatwave, the European Commission declined to take a pro or con stance on private-home air conditioning, saying it won’t micromanage consumer choices and that the issue should be addressed through energy efficiency and building renovations; it left room to revisit if political context changes and highlighted an Electrification Action Plan to power heating and cooling from cleaner energy. The debate ties into the broader Green Deal rethink toward net-zero and decarbonisation, with renewables accounting for about 47% of EU electricity in 2025.
