The production of cement is an energy-intensive process. Typically, energy consumption accounts for 20-40% of production costs. In 2008, the U.S. cement industry spent about $1.7 billion to purchase energy; around $0.75 billion of this was for electricity and $0.9 billion for fuels. The production of cement results in the emission of carbon dioxide from both the consumption
