The growth momentum of renewable energy is gratifying

In 2015, wind and solar power accounted for 23% of the world's total electricity generation. With the increase of wind power and solar power production capacity, the proportion is expected to rise to 30% by 2020.

Demand for renewable energy has remained high throughout the world. From wind turbines to solar panels, copper is a key component of renewable energy technologies. Wind turbines use copper as grounding material, transmission cables, transformers, frequency converters, surge protectors, and parts of their generators and control systems. [13] Only one wind power plant will use 4 million pounds (1800 tons) to 15 million pounds (6,800 tons) of copper.
