Both metal and copper oxidize when exposed to oxygen and this is a natural process. Copper that is exposed to the outside environment is more likely to turn green and that is why copper vases and decorative pieces in gardens are often green.
A 21st Century Solution. As the effects of climate change are more apparent the need to focus on renewable energy is even more important. Because copper is a highly efficient conduit it is used in renewable energy systems to generate power from solar, hydro, thermal and wind energy across the world. The use of copper helps reduce CO 2 emissions and lowers the amount energy needed to produce electricity! In many renewable energy systems 12-times more copper is used than in traditional systems to ensure efficiency. Copper is also one of the few materials that can be 100% recycled over and over again without a loss in performance. Today, renewable sources provide nearly one-quarter of the worldâs power and copper plays an important role in making it as efficient as possible, with minimal impact on the environment.
