According to the Department of Energy, fossil fuels are used to generate more than 85 percent of the energy used by the country. Electricity Coal alone provides half the electricity in the United States.
Although present in small amounts, < 1%, they have a significant effect on the hydration. Typically, they are present as sulfates, in the form of K 2 SO 4, Na 2 SO 4, Na 2 SO 4 •3K 2 O (aphthitalite), and/or 2CaSO 4 •K 2 SO 4 (calcium langbeinite), and they are usually deposited on the surface of the cement particles.
Cement production is both energy and emissions intensive: 60–130 kg of fuel and 110 kWh of electricity are required to produce a ton of cement,9 leading to emissions of around 900 kgCO 2/t. 10 Emissions result from direct energyrelated emissions (from fossil .
High fuel costs are a primary issue, and alternative fuels have emerged as a potential solution. The cement industry is now burning a variety of alternative fuels or waste products in its kilns. The chemical composition of alternative fuels determines their performance as well as their pollution potential.
The cement company is looking to burn raggertail, an approximately 60 percent plastic, 40 percent paper mixture, as an alternative fuel source to coal and natural gas.

Extraction and processing. Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
Because of the mix of fuels used, expenditures for space heating and water heating tend to be lower relative to other end uses. Space heating and water heating collectively accounted for 62% of energy consumption in 2015, but they were only responsible for 44% of energy costs because of the mix of fuels used to provide these end uses.
