renewable energy
Solar, wind and other non-fossil-fuel power generation — a fast-growing source of demand for copper, silver, aluminium and rare-earth metals used in panels, turbines and grid equipment.

Overview
Renewable energy — mainly solar photovoltaic and wind power, alongside hydropower and smaller contributions from geothermal and biomass — has grown into one of the fastest-expanding sources of metal demand anywhere in the industrial economy. Global installed renewable capacity reached 5,149 gigawatts by the end of 2025, according to the International Renewable Energy Agency, after a record single-year addition of 692 gigawatts, with solar photovoltaic alone accounting for roughly three-quarters of that year's new capacity.
What makes renewable energy unusually significant for metals markets isn't just its growth rate but its metal intensity: generating a given amount of electricity from solar or wind typically requires several times more copper, and often more of several other metals, than generating the same electricity from a conventional gas or coal plant, since renewable generation depends on more cabling, more power electronics and, in wind's case, large magnets.
Metals Used in Renewable Technologies
Solar panels rely heavily on silver for the conductive paste in their cells, along with aluminium framing and copper wiring connecting panels into arrays — solar has, in recent years, become one of the largest single sources of industrial silver demand, competing directly with silver's traditional investment and jewellery uses. Wind turbines, particularly the larger offshore models, use substantial quantities of copper in their generators and cabling, along with neodymium-based permanent magnets in many turbine designs, tying wind power directly to rare-earth magnet supply chains. Grid-scale battery storage, increasingly paired with both solar and wind to smooth out intermittent generation, adds lithium, cobalt and nickel demand on top of the generation hardware itself.
Growth Trajectory and Supply Pressure
With annual capacity additions still accelerating rather than plateauing, renewable energy's share of total global metal demand — particularly for copper, silver and rare-earth magnets — is widely expected to keep climbing for years to come, adding a structural demand layer on top of these metals' traditional industrial and consumer uses. That structural growth is part of why supply-side developments in these specific metals — a new mine, a smelter disruption, a critical-minerals policy announcement — tend to draw outsized market attention: the renewable buildout gives any resulting price move an unusually durable demand backdrop to play out against.
