Photo Credit: Alex Wilson In the years that I’ve been writing about energy and energy conservation (longer than I really want to admit), I’ve reported on several dramatic transitions in how we illuminate the exit signs in commercial buildings. For an energy geek, it’s been an exciting technology to watch. Why care about exit signs? Why do we even pay attention to exit signs—those ubiquitous red or green illuminated signs that direct our escape from a building should the need arise? They can’t use very much energy, can they? Each one uses relatively little electricity, but they are on all the time. And we have a lot of them in our schools, factories, and office buildings.
