A transition to renewable sources of energy will prompt a surge in demand for base metals in the coming years, Wood Mackenzie has predicted.

In a report published Monday, analysts at the energy consultancy said that as governments fulfil commitments to limit global warming, a growing reliance on solar power would boost demand for several non-ferrous metals.

Three metals in particular were named by Wood Mackenzie as commodities to watch: aluminum, copper and zinc.

The report’s authors outlined three possible scenarios for the metals, with demand growth for each depending on the success of international efforts to limit global warming.

Under the Paris Agreement — a landmark deal adopted in 2015 and signed by 196 countries — nations agreed to a framework to prevent global temperatures from rising by any more than 2 degrees Celsius compared to pre-industrial levels, although the treaty aims to prevent global temperature rises exceeding 1.5 degrees Celsius.

Aluminum

Wood Mackenzie’s base case scenario assumes that by the end of the century, temperatures will have risen by 2.8 to 3 degrees Celsius from pre-industrial times.

In this situation, aluminum demand from the solar power sector would rise from 2.4 million tons in 2020 to 4.6 million tons in 2040.

Typically, aluminum is used in solar panel frames and their structural parts, Kamil Wlazly, a senior research analyst at Wood Mackenzie, noted.

If the global temperature rise was kept between 1.5 and 2 degrees Celsius, however, it would mean that aluminum demand for solar power had reached between 8.5 million tons and 10 million tons a year by 2040, the analysts said.

In the most optimistic climate scenario, where renewable sources of energy were embraced more readily to cap warming at 1.5 degrees Celsius, demand from the solar sector would account for 12.6% of total global aluminum consumption by 2040 — up from 3% in 2020.

Copper

Demand for copper — used in high and low voltage transmission cables and thermal solar collectors — is also set for “notable gains” as solar energy becomes more mainstream, Wood Mackenzie said.

The report’s base case scenario predicted that demand for copper arising from solar power generation would rise from 0.4 million tons in 2020 to 0.7 million tons a year by 2040.

Copper consumption in the solar sector would increase to 1.3 million tons by 2040 if global warming was capped at 2 degrees Celsius. 

If temperature rises could be limited to 1.5 degrees Celsius, the industry’s consumption of the red metal was expected to jump to 1.6 million tons a year within the next two decades, the report claimed.

Zinc

Meanwhile, analysts noted that only zinc coatings could offer cheap, long-lasting corrosion protection, with the metal used in solar panels’ structural parts.

Currently, solar power installations account for around 0.4 million tons of annual global zinc consumption, Wood Mackenzie said.

If global temperatures were on track to rise by 2.8 to 3 degrees Celsius by the end of this century, this number was projected to grow to 0.8 million tons by 2040.

With temperature rises limited to 2 degrees Celsius, zinc consumption would increase to 1.7 million tons a year by 2040. If warming was successfully limited to 1.5 degrees Celsius, zinc consumption in the solar sector would rise to 2.1 million tons a year by 2040, analysts predicted.

Wood Mackenzie’s predictions for the three metals were only around demand coming from the solar power industry, and did not speculate on total global demand.

Wlazly pointed out in Wood Mackenzie’s note on Monday that falling production costs and efficiency gains had lowered the price of solar power around the world.

“As a result, solar has become cheaper than any other technology in many parts of the U.S. and several other countries across the globe,” he said. “As costs continue to fall, solar’s share of power supply will rise and begin to displace other forms of generation. This presents a huge opportunity for the base metals sector.”

New ‘world’s lightest, most efficient’ e-bike motor lands on another model

New 'world's lightest, most efficient' e-bike motor lands on another model

Last week, we reported that the e-bike world had a new motor claiming to be the lightest and most efficient. Now, we’re already seeing TQ’s new TQHPR40 motor proliferate on more road and gravel e-bikes, including the recently announced E-ASTR from Ridely.

Ridley’s new E‑ASTR brings lightweight electric assistance to its already impressive ASTR gravel platform, powered by the cutting-edge TQ HPR40 mid-drive system. Unlike bulkier e‑bike setups, this system adds just 1.17 kg (2.6 lb) at the crank and a discreet 1.46 kg (3.2 lb) and 290 Wh battery hidden within the downtube, keeping the frame’s silhouette nearly identical to the non-electric version of the same bike. According to BikeRumor, riders looking closely might spot only a slightly fatter downtube, internal cable routing, and a handlebar-end LED indicator, giving visual clues without shouting “electric bike.”

What the E‑ASTR gives up in sheer power from the petite motor, it gains in ride feel. The HPR40 is said to deliver a modest 40 Nm of torque and up to 200W of assist, or enough to smooth out climbs or offer a tailwind on gravel without overpowering the rider. With support cut off at 25 km/h (15.5 mph), pedal responsiveness remains natural and fluid. Combined with the ASTR’s race-inspired geometry, the bike looks to offer sharp handling and comfort suited to the rigors of modern gravel routes.

Ridley is currently offering the E‑ASTR in three spec levels: a value SRAM Apex XPLR AXS build €7,199 (or approximately US $8,500), a mid-range SRAM Rival XPLR AXS 1×13 version for €8,199 (or approximately US $9,700), and a top-tier Shimano GRX 2×12 Di2 model for €8,899 (or approximately US $10,500). Each features high-end drivetrains, integrated cockpit options, carbon wheels, and industry-standard gravel brakes and tires. With its race-ready frame and stealthy, lightweight e‑assistance, the E‑ASTR is positioning itself as a high-performance gravel machine that stays true to its roots, delivering help when needed, without overshadowing the rider.

Wait, you’re telling me that’s an electric bike?!

Ultra-lightweight motors like the TQHPR40 are quietly reshaping the e-bike industry by making electric assistance almost invisible, both in looks and in feel. As systems shrink and integrate more seamlessly into traditional bike frames, they’re opening the door to new categories of performance-oriented e-bikes that preserve the ride dynamics of analog bikes while offering just enough support when it counts.

For riders who value a natural pedaling experience but still want a little help on climbs or longer days, and especially for aging riders who want to maintain their riding habits despite father time taking an impact on joints and muscles, these minimalist systems are proving that you don’t need a bulky battery or a massive motor to get the benefits of going electric. The result is a wave of stealthy, high-performance e-bikes that are less about replacing effort and more about enhancing the ride.

Hyundai is about to reveal a new EV and it could be the affordable IONIQ 2

Hyundai is getting ready to shake things up. A new electric crossover SUV, likely the Hyundai IONIQ 2, is set to debut in the coming months. It will sit below the Kona Electric as Hyundai expands its entry-level EV lineup.

Is Hyundai launching the IONIQ 2 in 2026?

After launching the Inster late last year, Hyundai is already preparing to introduce a new entry-level EV in Europe.

Xavier Martinet, President and CEO of Hyundai Europe, confirmed that the new EV will be revealed “in the next few months.” It will be built in Europe and scheduled to go on sale in mid-2026.

Hyundai’s new electric crossover is expected to be a twin to the Kia EV2, which will likely arrive just ahead of it next year.

It will be underpinned by the same E-GMP platform, which powers all IONIQ and Kia EV models (EV3, EV4, EV5, EV6, and EV9).

Like the Kia EV3, it will likely be available with either a 58.3 kWh or 81.4 kWh battery pack option. The former provides a WLTP range of 267 miles while the latter is rated with up to 372 miles. All trims are powered by a single electric motor at the front, producing 201 hp and 209 lb-ft of torque.
