Embodied energy is the energy consumed by all of the processes associated with the production of a material or an assembly like a building, from the mining and processing of natural resources to manufacturing, transport and product delivery. EE does not include the operation and disposal of the building material, which would be considered in a life cycle approach. EE is the ‘upstream’ or

Energy-intensive manufacturing accounted for a little more than half of total industrial energy use. Although the cement industry used only one-quarter of one percent of total U.S. energy, it is the most energy-intensive of all manufacturing industries, with a share of national energy use roughly 10 times its share of the nation''s gross output of goods and services .

Though “cement” and “concrete” are often used interchangeably, concrete is actually the final product made from cement. The primary component of cement is limestone. To produce cement, limestone and other clay-like materials are heated in a kiln at 1400°C and then ground to form a lumpy, solid substance called clinker; clinker is then combined with gypsum to form cement.
