Christina Gomez, energy and sustainability manager for the National Aquarium in Maryland, is looking back at the success the organization has had over the past two years in shrinking its environmental footprint. It is impressive. But bigger challenges lie ahead. The organization has a huge electricity bill, totaling $1.5 million in 2013 alone. She has three options she is considering to lower the bill and green the aquarium’s operations further. Students are asked to weigh the pros and cons of each and choose the best solution.
