text: Peak copper is the point in time at which the maximum global copper production rate is reached. Since copper is a finite resource, at some point in the future new production from mining will diminish, and at some earlier time production will reach a maximum. When this will occur is a matter of dispute. Unlike fossil fuels, copper is scrapped and reused, and it has been estimated that at least 80% of all copper ever mined is still available (having been repeatedly recycled).
  Copper is among the most important industrial metals, ranking third after iron and aluminium in terms of quantity used. It is valued for its heat and electrical conductivities, ductility, malleability and resistance to corrosion. Electrical uses account for about three quarters of total copper consumption, including power cables, data cables and electrical equipment. It is also used in cooling and refrigeration tubing, heat exchangers, water pipes and consumer products.
  Copper has been used by humans for at least 10,000 years. More than 97% of all copper ever mined and smelted has been extracted since 1900. The increased demand for copper due to the growing Indian and Chinese economies since 2006 has led to increased prices and an increase in copper theft.
