Though most people are now aware that global warming is a problem, awareness does not necessarily spur a change in behavior. For me, a sense of urgency developed by degrees. A photo seen, an article read--all describing a radically changed world because of our consumption of ancient fuels. Oftentimes, matter-of-fact descriptions had a greater impact than high volume soundings of alarm. At some point--maybe it was a description of how our CO2 emissions are fundamentally changing the chemistry and ecological destiny of the oceans--I realized the status quo could not continue.
Strangely, the realization need not lead to a burden of guilt but instead to a sense of empowerment. Each of us has the power to reduce our impact. The first thing to do is to discern when you're consuming fossil fuels and when you're not. This is not so easy, particularly around the house, where silent appliances can nonetheless be consuming large quantities of electricity. Unfortunately, your electric meter is of little use, since it's hard to read and located outside somewhere in the bushes. Not a convenient setup for providing feedback. (A separate post will describe how to measure your energy use at any particular moment.)
Just as my sense of urgency was fed by quiet descriptions rather than loud pronouncements of imminent doom, there is another sort of quiet that can power change in our lifestyles. The silence I refer to in the title of this post has more to do with awareness than with sound. Right now, my computer is drawing nearly 200 watts, the refrigerator several rooms over is cycling on and off, using another 200 or so when it's on. The TV and cordless phone are drawing a few watts, even though they are turned off. Beyond that, things are pretty "quiet" around here. If I decided to use the electric dryer rather than a clothesline, the house would suddenly be drawing an extra 3700 watts! Though the dryer's quiet as a whisper, it's possible to "hear" this as a raucous noise of consumption.
Fortunately, the clothes are air-drying, and if I turn off the computer, the house's power consumption gets quieter still. To be aware of this sound of silence is to relax in a new way. This awareness can be applied to your personal energy consumption at any moment in your day. Even though the street traffic may be loud, to walk or bike somewhere is to experience silence, whereas to drive a car is to hear a racket (consumption speaking), even if the windows are up.
The impact each of us has on the world as we consume fossil fuels is abstract. But the evidence is in--our collective impact is real. As each of us comes to realize what is at stake, it's understandable if we all feel a growing sense of tension between our lifestyles and the planet's future. Develop an awareness, "listen" to how much power you're consuming, find ways to turn down the volume, and discover in this all-too noisy and abstract world a new feeling of relaxation that has silence at its core.
