Innovations: Introduction to Copper: Mining & Extraction

Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. However, by far the greatest extension in the use of copper resulted from Michael Faraday's discovery of electromagnetic induction in 1831 and the way that the effect could be used to generate electricity.

Geothermal heat pump Wikipedia

A geothermal heat pump (GHP) or ground source heat pump (GSHP) is a central heating and/or cooling system that transfers heat to or from the ground. It uses the earth all the time, without any intermittency, as a heat source (in the winter) or a heat sink (in the summer). This design takes advantage of the moderate temperatures in the ground
