Renewable energy sources such as solar, wind, tidal, hydro, biomass, and geothermal have become significant sectors of the energy market. The rapid growth of these sources in the 21st century has been prompted by increasing costs of fossil fuels as well as their environmental impact issues that significantly lowered their use.Copper plays an important role in these renewable energy systems. Copper usage averages up to five times more in renewable energy systems than in traditional power generation, such as fossil fuel and nuclear power plants. Since copper is an excellent thermal and electrical conductor among engineering metals (second only to silver), electrical systems that utilize copper generate and transmit energy with high efficiency and with minimum environ-mental impacts.
