Margaret Rudolph worked on an energy efficiency guidebook and prepared case studies to engage more sites in energy efficiency.


Margaret Rudolph spent her summer at Cummins, a manufacturer of large diesel and natural gas engines as well as related components headquartered in Columbus, Indiana. Rudolph, an MBA student at the Mason School of Business, College of William & Mary, looked at ways to expand the reach of the existing energy efficiency program in the 36,000 employee company. The existing program had already created annual savings of more than $10 million in utility costs and more than 200,000 tons of greenhouse gas emissions from a variety of sites.


Rudolph worked with a team of facility and environmental leaders to create an energy efficiency guidebook and to prepare case studies of successful implementations of energy efficiency solutions. The guidebook will serve as a tool to educate employees and managers across the company on the potentials of actively participating in the energy efficiency program. Case studies show the benefits of implementing energy efficiency, serve as a depository of ideas to evaluate at each site and provide a basis to leverage best practices. Cummins projects continue to save 10 percent of energy costs at each site that implements an active energy efficiency program with a projected program expansion at a rate of 20 sites per year.

Potential Impact

Estimated savings generated by engaging more sites add up to a potential saving of 144 metric tons of CO2 emissions per year.
