Bringing Solar Energy Technology to Campus

Have you ever used solar energy to charge your laptop or cellphone? Have you ever had the chance to watch a battery’s charging meter go up as it takes in power from the sun? Would you like to learn more about the efficiency and potential of solar electric technology?

A study is about to begin on campus involving solar energy technology. Goal Zero is a leader in portable solar equipment technology, and eight of their systems are now here on campus. Two of these systems are meant for larger scale use (for a family or group housing situation); six of them are smaller, relatively portable, and meant for individual usage. A collaborative project between Dr. Joshua Pearce’s lab and Dr. Chelsea Schelly of the Department of Social Sciences, the goal of the project is to temporarily install these systems into Greek housing, shared student houses, dorms rooms and university apartments so that students can get firsthand experience using solar energy technology. After they’ve spent some time living with solar electricity, participants will be asked about their energy behaviors – how they use and think about energy. This project was recently discussed in the Lode.

Solar electric technology provides one means of decreasing our reliance on fossil fuels and localizing energy production. Participating in this study will provide students with exposure to the latest in portable and small scale solar electricity generation, and will provide researchers with information regarding how technology impacts our energy behaviors and attitudes. If you live in Greek organization housing, share a house with other students, or would be interested in participating as an individual, we’d love to hear from you! Please contact cschelly@mtu.edu.

Saying goodbye

Conservation biology is an often-dismal discipline. For every story with a happy ending, there are hundreds with a tragic one – and often beyond that, thousands that end without us ever knowing. The loss of species that endear themselves to us is always a particularly difficult goodbye.

The monarch butterfly is swiftly approaching a sad fate. Robbed of its critical food supply (milkweed) by industrial agriculture in the midwestern region of North America, fewer monarchs are able to reproduce and migrate back down to its wintering habitat in Mexico. This year, surveys of Mexican forests have recorded the lowest number of returning monarch butterflies since these surveys began. The monarch migration is a fantastic spectacle; these butterflies migrate thousands of miles in spring and fall. Their large size and colorful markings make them familiar to most, and hence their declining numbers are likely to be noticed. That is the good news.

In this conservation case, everyone can help. Planting milkweed (the native species to North America, not tropical species such as Asclepias curassavica) in your front and back yard will help replace the feeding stations that the butterflies have lost with agriculture, and allow them to build up their numbers. Large populations help the butterfly persist through late springs (which disrupt their breeding schedule) and extreme weather events that can kill them outright.
