I’m writing a mid-week reflection on our intensive teaching week for the Energy Practices module. What struck me is a realization of how energy practices penetrate almost every aspect of our lives. Dr. Sandra Bell lectured us on Practice Theory and Dr. Simone Abram followed up with a lecture on Actor Network Theory. Both of these frameworks illuminate the way in which practices pertaining to energy use associate with an essentially unlimited amount of different actors. If there is one lesson to glean from both of these presentations it is that most actors, to include human and non-human beings, are connected in unexpected ways. These perspectives provide the scholar a vocabulary for explaining these associations. We were asked to think of an energy practice such as turning off the lights when leaving the house. At first glance this practice may seem like simply a matter of individual choice. However, upon examination, it is clear that many actors play distinct roles in this practice. For instance, some cultures highly value entering a ‘warmly’ lite home. Some people, especially those who live alone, feel a sense of comfort when entering a house with lights. Additionally, lights provide a sense of security for some when they are away from the house as a means to ward off predators. For people with limited mobility, the low placement of switches may be too much of a hassle. From a different perspective, cheap electricity (or electricity perceived as clean from low-carbon sources) lower the incentive to switch off the light when leaving the house. It is clear from this small list of factors that the practice of turning on or switching off lights is not only a matter of individual choice or a product of structure, but a practice positioned within a web or interrelated actors.
