New zinc battery technology shows promise as a cheaper alternative to lithium batteries to store renewable energy like wind or solar. Zinc also protects steel against weather and corrosion, producing brass and bronze, and in die-casting to produce a wide range of metal products. Zinc can increase crop yields and crop quality. And, as an essential nutrient in human development and disease prevention.
Copper is essential for energy storage, electrical propulsion (e.g. electric vehicles), and renewable energy. As the adoption of wind and solar technologies grows, so will the need for copper
