In both scenarios, EVs and battery storage account for about half of the mineral demand growth from clean energy technologies over the next two decades, spurred by surging demand for battery materials. Mineral demand from EVs and battery storage grows tenfold in the STEPS and over 30 times in the SDS over the period to 2040.
Install the inverter near the main electrical panel. In some cases, use micro-inverters attached to individual panels instead of a central inverter.
After the first oil shock in 1973, researchers at the Odeillo solar furnace turned their attention more to converting solar energy into electricity and hybridizing energy production.
The Panatère adventure began five years ago when its founder, Raphaël Broye, had the idea to transform a problem into an ecological solution. “We have been active in watchmaking subcontracting for around forty years and five years ago we found ourselves faced with major problems with the supply of quality steel,” he explains. “We approached several large steelmakers in Europe but found ourselves faced with quantity problems.
“Nucor is one of the most efficient and cleanest steel producers in the world and we are always looking for ways to reduce our carbon footprint,” said Leon Topalian, President and CEO of Nucor Corporation.
Another option is to adopt HVDC systems more widely, which uses one-third less metal compared to AC systems and are capable of transporting more electricity. A wider uptake of HVDC systems could reduce combined demand for copper and aluminium in 2040 by 4 Mt (or 15%) in the SDS.

Installing solar panels on a trapezoidal metal roof requires specialized mounting brackets designed to fit the contours of the roof profile. The process involves careful planning to align with the roof’s distinctive wave-like pattern.
cem% recycled stainless steel in a short circuit and shaped by a concentrated solar oven specially developed for this type of product Up to 400 tons of steel and titanium recycled every year
Electricity networks Electricity networks are the backbone of secure and reliable power systems, and have a vital role in integrating clean energy technologies
He also wants to continue to develop his own practice, eventually having a manufacturing process for his workshop that runs completely on solar, wind and human power.
The principle is not new, but the company claims it can take it much further. “So far, the heat has reached between 500 and 600°C,” Bill Gross points out. Enough to generate electricity through rotating turbines. But doubling this temperature would open up new opportunities by unlocking a series of chemical reactions.
Over 90% of the EVs marketed today use permanent-magnet synchronous motors due to their high efficiency, compact size and high power density. However, their use of REEs such as neodymium, praseodymium, dysprosium and terbium – upwards of 1 kg per motor – raises concerns given the geographical concentration of raw material and processing in China, the lack of recycling pathways and high price fluctuations.
