Climate & Energy News: 2 November 2026

Tesla launched Heat Pump Optimization for Powerwall 3 and three-phase Powerwall 3P, letting the battery tell a compatible heat pump when to run harder and store cheap or surplus solar energy as hot water. The feature is live in Europe only and uses SG-Ready signals, with no cloud integration and no app on/off toggle. A 300-liter tank heated an extra 30 degrees can store 10.5 kWh of thermal energy, using 3.5 kWh of electricity at a COP of 3.

Two new reports say methane measurements are being manipulated and underestimated, with one analysis commissioned by Greenpeace International examining global warming potential, or GWP. Researchers warn that rich, livestock-heavy countries could use GWP to measure livestock emissions while continuing to emit large amounts of methane. The debate arrives before COP31, after a U.N. report said the world has a vanishing chance of limiting warming.

Janus Electric, an Australian firm, is bringing Class 8 heavy duty electric truck conversions to North America, with a battery-as-a-service model that includes charging and swapping. A modern swapping station can change a spent electric car battery for a fresh one in minutes. That matters in trucking, where waiting for a charging station can be a non-starter.

US startup Revoy announced a swappable battery retrofit for Class 8 diesel trucks last summer.

BYD sold 305,743 battery electric vehicles in October, a record that exceeds the 262,500 EVs sold in the US during the entire third quarter. The company's total new energy vehicle sales reached 490,168 units, up 11% year over year. BYD exported 170,194 vehicles in October and expects overseas shipments to reach 2 million by the end of 2026.

RWE and partners announced that renewable hydrogen produced at Lingen reached Marl Chemical Park, roughly 120 kilometers away. The milestone marks the first time the hydrogen backbone achieved this distance, but the announcement did not disclose the quantity received or the price paid. Germany's approved hydrogen core network covers 9,040 kilometers with expected investment costs of 18.9 billion euros.

Carbon Brief has compiled positions from around 100 documents as delegates prepare for COP31 in Antalya, where climate finance and the just transition mechanism are on the agenda. Australia will lead the negotiations while Turkey hosts, and Turkey is also promoting electrification, oceans and green industrialisation. Parties remain divided over the scope of the Belém-Antalya mechanism and whether it should be tied to finance.

Electric trucks made up 50.3% of heavy trucks sold in China in September, 33,100 units, up 37% from a year earlier. China's diesel demand is on track to fall about 230,000 barrels per day this year, with battery and natural gas trucks driving the shift. CATL says new energy trucks will be half of China's annual truck sales by 2028.

Envision Energy said it deployed the world's first commercial integrated 800 V DC power system in a large-scale AI data center, at its Galaxy campus in Ulanqab, China. The system combines solid-state transformers and battery storage to match power with computing demand and absorb GPU load swings. The campus began operating in August 2026, has a planned 3 GW capacity, and is expected to draw more than 80% of its power from renewables.

Corporate funding in the global solar sector grew 45% year over year through the first three quarters of 2026, reaching $25.1 billion across 170 deals. Debt financing drove much of the growth, totaling $20.4 billion, while public market financing also increased. Venture capital funding for the sector contracted by 31% during the same period.

Armenia introduced interest rate subsidies for loans and leasing of storage systems paired with solar energy. Businesses can receive subsidies of 6 to 10 percentage points for up to seven years, depending on the financing arrangement and currency. The measure aims to support the country's growing solar sector, which accounted for 16.3% of electricity generation last year.

Greenpeace activists dropped boulders in the Southern North Sea marine protected area to create a barrier against bottom trawlers. The action closed 116 square kilometers of the area to industrial fishing, aiming to protect harbor porpoises. Greenpeace stated that bottom trawlers logged more than 37,200 fishing hours in the zone in 2025.

Japan's environment ministry and METI proposed that commercial solar owners disposing of 50 metric tons or more of panels file an advance disposal plan. The threshold would set which operators face the strictest duties under a new recycling law expected to take effect around early December 2027. The ministries said 50 metric tons would cover 7,398 facilities and capture 38.3% of panel waste expected from 2027 to 2050.

Aida Havel, a Dare County commission candidate, said a 45-minute drive has become a four-hour logistical exercise after Highway 12 closed again on Hatteras Island. The Outer Banks are in North Carolina's first congressional district, where a race has cost more than $52 million and made it the most expensive in US history. A lackluster response to flooding disasters is eroding Republican support in one county.

Forecast models suggest the stratospheric polar vortex could weaken significantly over the next 10 days, earlier than usual for the season. A major sudden stratospheric warming event is possible, which could increase the chance of persistent high pressure and colder conditions across northern Europe in coming weeks. A Mediterranean low is also expected to bring heavy rain and strong winds to central and southern Italy on Monday.

China is targeting renewable sources for more than 80 percent of electricity used by new data centers in major computing hubs. Envision Energy began operating a data center campus in Inner Mongolia powered by renewable electricity, with plans to expand beyond 2 gigawatts. China aims to expand its AI computing capacity more than sixfold by 2030.

A poll of 1,167 likely US voters found that 58% believe climate change will hinder their ability to achieve or maintain the American Dream over the next 20 years. This includes 42% of Republicans. More than half of voters are worried that climate change will make life more expensive, a concern that outweighs fears about warmer temperatures or extreme weather.

Starting in February 2027, new e-bike batteries sold in the European Union must carry a digital battery passport accessible via QR code. The system provides information on battery health, capacity, and carbon footprint, which could help consumers assess used e-bike batteries. While the rules are European, the increased transparency may eventually benefit American e-bike riders.

Two Brookings reports show DOGE eliminated $468 million from Indian Country, about half for environmental and natural resources, while the One Big Beautiful Bill Act killed many Inflation Reduction Act funding streams. In Kotzebue, Alaska, a canceled $20 million EPA wind grant leaves a community that relies on diesel with a paused project that would have cut diesel reliance to 40% to 50%.

The Osage Nation's Department of Natural Resources has plugged about 160 orphan wells since its federally funded program began, with 70 to 80 this year. Crews have inspected at least 2,500 to 2,700 wells and found records often wrong, including a well open to 2,400 feet despite a reported cement plug. The pace picked up after the Orphan Wells Plugging Office revised tribal grant guidelines in March.

A Guardian investigation found vessels from Grimaldi Group, Corsica Ferries, Baleària and Moby Lines often crossed the Pelagos sanctuary at 15 knots or more. The IMO advised ships of 300 gross tonnes or more to sail at 10 to 13 knots in the area, where collisions at 15 knots or above almost always kill cetaceans. The area holds about two-thirds of the Mediterranean's fin whales and more than a fifth of its sperm whales.

After decommissioning, a used solar module can take hundreds of different pathways. Different policies, technologies and capabilities make each recycling process unique, so the optimal route can vary greatly with regional issues and other factors.

A conservative commentator says Australia's Coalition is abandoning climate measures by seeking to remove net zero targets from law and abolish the Net Zero Economy Agency. The plans diminish renewable and clean energy bodies, remove EV tax concession, battery rebates and Scope 3 reporting, and cancel the annual Climate Change Statement. The writer argues the changes may face Senate resistance and depart from conservative conservation values.

A UN-backed report says Earth's ice and snow face permanent damage if warming overshoots 1.5C, even briefly. It urges removing carbon to bring long-term warming ideally below 1C by 2150. Scientists say high overshoot under current policies could thaw near-surface permafrost and disrupt ocean circulation.
