Copper is a strategic metal that plays a key role in the world’s move to clean energy. It appears on critical mineral lists in many countries, including the United States, Canada, India, South Korea, and Japan. Copper is highly recyclable and has excellent electrical and thermal conductivity. It is used in power grids, electric vehicles, wind turbines, solar panels, and digital infrastructure.
Renewable energy systems need up to five times more copper than conventional energy systems. The International Energy Agency predicts that copper demand for clean energy could almost double by 2050. Mining forecasts show that copper demand over the next decade may surpass the total mined in history. Copper reduces energy losses and helps integrate renewable energy into electricity grids.
Copper is one of the most recyclable metals on Earth. Nearly 80 percent of all mined copper is still in use today. About one-third of global copper demand is met through recycling. Recycling reduces the need for new mining and lowers environmental impacts. Mining companies are improving water and energy use, working with communities, and managing environmental impacts.
Malachite is a vibrant green copper ore. It has been used as a copper source and pigment since Neolithic times. Malachite has also featured in jewellery, art, and spiritual objects. It forms when copper-rich minerals like chalcopyrite and bornite are exposed to water, oxygen, or carbon dioxide. The copper then combines with other chemicals to form deposits. Malachite comes in many shapes, such as rounded lumps, fibres, icicle-like coatings, or powdery crusts. It is often found in volcanic areas.
Copper and malachite are central to the clean energy transition. Copper’s conductivity and recyclability make it essential for renewable technologies. Malachite highlights the potential of sustainable mineral recovery. Responsible mining and recycling of strategic metals like copper will help power the global energy transition while protecting the environment.
