Introduction
Eco-friendly metals are materials essential for green technologies and crucial to decarbonizing energy, transport, and industry. Their unique properties support clean electricity, battery storage, and light-weighting of vehicles. Surging global demand for these metals fuels the growth of renewables and electric vehicles yet puts pressure on supply chains and sustainability. World investments exceeding $2.1 2.1trillion are required by 2050 to meet net-zero needs, with projected supply deficits of 30% for copper and 40% for lithium by 2035..

Copper: The Energy Backbone
Copper is the primary metal enabling energy transition technologies. Its global output reached approximately 22 million tons in 2023, with demand projected to soar beyond 50 million tons by 2050. Wind turbines, solar panels, and EVs rely on copper wiring and components, and renewables use five times more copper per installed megawatt than fossil fuel plants. By 2025, demand from solar, wind, and EVs could account for 2.8million tons, nearly 11% of total copper use.

Aluminum: Lightweight Versatility
Aluminum is lightweight and resists corrosion, making it invaluable for solar panel frames, wind turbine blades, and transmission lines. Annually, global aluminum demand in renewables is rising by around 5%, underpinned by solar installation growth. Aluminum makes up over 85% of solar panel components today and is central to light-weighting EVs for better range. Its recyclability underpins sustainability.You want to know more about eco friendly metals also check this
