Mark Braby recommended five different energy efficiency projects for Raytheon.


Mark Braby spent his summer as a Climate Corps fellow at Raytheon, a global aerospace and defense company headquartered in Waltham, Mass. Braby, an MBA student at Duke University, worked with Raytheon's Network Centric Systems (NCS) division in Dallas, to identify energy reduction opportunities within the company. NCS is a significant consumer of electricity, using almost 225 million kWh of electricity annually.


Based on his analysis of the division's energy use, Braby recommended several initiatives including reducing the company's computing footprint by replacing a portion of their PC environment with thin clients. Thin clients run programs and store data centrally on central servers. They are significantly more energy efficient than PCs, using as little as 6 to 20 watts of electricity (compared to 70 to 150 watts to run PCs). For companies with large computing environments, like Raytheon, switching to thin clients can add up to significant savings.

Potential Impact

Implementing this virtualization project, along with four other energy-efficiency projects Braby recommended, could save Raytheon up to $3.4 million in operating costs over the life of the projects and avoid up to 1,586 metric tons of CO2 emissions annually.
