The U.S. mining industry provides essential raw materials like coal, metals, minerals, sand, and gravel to the nation’s manufacturing and construction industries, utilities and other businesses. Nearly 24 tons of material are consumed annually per capita in the United States;4 further, common consumer products can use a vast variety of mined materials, for example, a telephone is manufactured from as many as 42 different mined materials, including aluminum, beryllium, coal, copper, gold, iron, limestone, and silica. Mining these materials consumes significant energy – in 2002, the mining industry spent $3.2 billion on energy, or 21% of the total cost of its supplies (not including labor).5 Given the large role mining industry plays in the U.S. economy and the energy intensity of the mining processes, tapping into the potential for energy savings across different mined commodities could yield significant impact. The magnitude of these potential savings can be quantified using the energy bandwidth analysis – a method for estimating the opportunity in various processes based on their theoretical energy consumption and the practical minimum energy use achievable by implementing R&D results and best practices.
