DAR ES SALAAM, Sept. 29 -- THE green-energy revolution is reshaping the global economy, with rapid growth in solar power, wind energy, electric vehicles, batteries, green hydrogen and energyefficient technologies.

However, this transition demands significant quantities of minerals, metals, manufacturing capacity, transport and infrastructure.

From an economic standpoint, this reveals a key paradox: A truly green economy cannot exist if the supply chain for green technologies remains environmentally damaging, socially harmful or highly carbon-intensive.

Manufacturing solar panels, batteries, electric vehicles and wind turbines relies heavily on minerals such as copper, lithium, nickel, cobalt, graphite and rare earth elements. Extractin...
