As she began to examine questions about life-cycle analysis and resource efficiency, she says “I realized…to get a sense of what’s going on, you can use fairly simple math. I decided that would be a great place to bring in students, to give them the confidence to apply straightforward mathematics to analyze complex situations.”
This urge to combine a personal passion for sustainability with her career resulted in Dr. Mason’s first-year seminar, Counting on Sustainable Energy: Does it Add Up?, which she is currently teaching for a second time this spring. The simple addition, multiplication, and conversion involved in the course are far from her traditional research field of combinatorics, but Dr. Mason’s course demonstrates how “pretty basic mathematics can be used to do some powerful things.”
Counting on Sustainable Energy fosters a greater understanding of alternative energy and arms students with the ability to critically evaluate assertions about the relative environmental impacts of various fuel sources. “One of the biggest things that I want my students to get out of this class is getting comfortable taking claims and evaluating them for themselves. If someone says something is better for the environment, I want my students to be able to go home and verify that claim.”
Over the course of a semester, Dr. Mason’s students will investigate a wide array of alternative energy sources, including solar, hydro, wind, and geothermal. They will examine how much energy these sources could produce on Wake Forest’s campus and how much energy a Wake Forest student consumes each day. By the end of the semester, students will find an answer to the course’s central question: Could we, with our current consumption patterns, rely on sustainable energy at Wake Forest University? If the answer is yes, students will explain exactly how a switch to sustainable energy might be feasible in their final paper. If the answer is no, students will lay out a plan to reduce energy consumption.
Much of Dr. Mason’s FYS is hands-on. Her students began the course by measuring their own electricity consumption with a Kill-a-watt, an exercise designed to give them an idea of scale when they use the watt or kilowatt hour (kWh) as a unit of measure. Recently, her students completed the construction of miniature wind turbines, an exercise designed to familiarize them with the mechanics of wind energy. As part of their final project, students will develop and staff interactive educational booths at Food for Thought, this spring’s Earth Day celebration for the Wake Forest community.
In addition to readings and class projects, Counting on Sustainable Energy includes a line-up of guest speakers, including a representative from Volt energy (the company responsible for the solar panels on The Barn) and an environmental engineer working in wind turbine installation. Students will visit a land fill and a geothermal installation. So far, Dr. Mason’s students have matched an impressive syllabus with impressive work product. Dr. Mason reports her students are highly motivated by the subject matter, explaining “because they are passionate about [sustainability], they are willing to do the leg work.”
The latest version of Counting on Sustainability is a result of Dr. Mason’s participation in the Magnolias Project, a WFU faculty workshop on integrating sustainability across the curriculum. An assigned reading on the moral ecology of everyday life (from Higher Education for Sustainability) inspired Dr. Mason to take the focus of Counting on Sustainability from a national level down to a campus level; her students have benefited from an opportunity to relate to their course material directly.
Not only did the Magnolias Project allow Dr. Mason to refine her syllabus, she also made valuable connections to faculty from different disciplines. This network continues to be source of ideas and feedback, which Dr. Mason finds particularly valuable as a mathematician teaching a writing-intensive course. This spring, she will co-lead the second iteration of the Magnolias Project with Dr. Lucas Johnston, a faculty member in the Religion department and another member of the Magnolias Project’s first cohort.
Unsurprisingly, Dr. Mason also integrates sustainability into her life beyond the classroom. When moving to Winston-Salem, she intentionally purchased a home within walking distance from campus and often uses a bicycle for transportation. An avid hiker, she partially attributes her interest in sustainability to a love of the outdoors, saying “I love hiking and I really value being able to explore untouched places. I worry our society is moving towards less and less of these beautiful, spectacular places.”
A passion for sustainability runs in Dr. Mason’s family. The environmental engineer who spoke to her class about wind turbines was her father and her brother is an urban planner, currently tackling solutions for mass transit in developing countries. Her brother also helped her tackle a compost bin project in her backyard and Dr. Mason plans to put her compost to good use this year. She muses “I love being able to go out and make a salad with ingredients straight from my backyard, there is something really satisfying about that.”
Dr. Mason’s academic innovation is possible through the generous support of the university, for which she is continually grateful. Her students are equivalently grateful for Dr. Mason, especially those like sophomore Caroline Waco, whose experience in Dr. Mason’s FYS last year inspired her to do independent research on the factors impacting the payback period for solar photovoltaic panels. Dr. Mason explains that her promotion of sustainability at Wake Forest naturally flows from her interest in the topic. She says “I’ve always believed in following my passions, and hopefully that leads to a strong contribution to my community.”
