Energy Management

In 2010, the company’s commitment to energy management translated into an investment of nearly $16 million in projects to increase operational energy efficiency. CEMEX USA reduced its total primary energy consumption in 2010 equal to a reduction of nearly 11,000 metric tons of CO2 emissions. The amount of energy saved is equivalent to providing electricity to approximately 1,500 American homes for a year.

Dayton Power & Light

CEMEX’s cement plant in Fairborn, Ohio decreased electric power consumption used for compressed air by more than half, earning the company a $226,000 rebate from Dayton Power & Light (DP&L). The decrease in electricity consumption also reduces the amount of CO2 emitted into the atmosphere annually by more than 1,475 metric tons.

CEMEX USA’s rebate is the largest that DP&L has paid to date as part of its energy efficiency programs offered to customers to meet Ohio’s energy efficiency targets to reduce electricity consumption by 22 percent by the end of 2025.

ENERGY STAR

Five of CEMEX’s U.S. cement manufacturing plants received the 2011 ENERGY STAR® award. Our plants in Clinchfield, Ga.; Louisville, Ky.; Miami, Fla.; New Braunfels, Texas; and Demopolis, Ala. received the awards in recognition of superior energy performance. 2011 marks the fifth consecutive year for the plants in Clinchfield, Ga., and Louisville, Ky. to receive the award and the third consecutive year for the plant in Demopolis, Ala.

Over the last year, these plants have conducted process surveys, installed variable-frequency drives to replace damper control on fans, installed area power metering equipment to better analyze consumption, installed more efficient motors, and conducted energy audits to reduce unnecessary power usage. All of the plants improved their energy performance using the ENERGY STAR® guidelines for Energy Management developed by the EPA and DOE.
