power on
Flip the switch and, voila!, there is light. It's something I do everyday, without really thinking about it. I take electricity for granted and I know that I shouldn't, mainly because I found myself at the heart of the so-called Triangle of Darkness during the ice storm that ravaged Quebec in 1998. For twenty-eight days (minus the few hours between when John purchased a generator and when he deemed it defective because, in addition to generating power, it was generating an unsettling blue flame) lightbulbs were useless and I was forced to appreciate what life was like before Franklin's potentially idiotic kite experiment.
Given that producing light is as simple as flipping the switch, it's easy to ignore where the power comes from and even easier to leave lights on unnecessarily. In addition to turning superfluous lights off, my efforts to reduce my carbon footprint have included purchasing compact fluorescent bulbs in order to reduce power consumption for the purpose of illumination. The equation is simple: less power consumed = less power generated = less carbon emissions.
In the two places I've lived before now, the nature of the source of the electricity was implicit in the names printed on my utility bills: Hydro Québec and BC Hydro. I was always left wondering what impacts my effort to reduce my electricity consumption had if the bulk of the environmental impacts associated with producing the power were incurred in the past, when the dam was built and the landscape was flooded and the power lines were erected. The ongoing generation of hydroelectricity is considered relatively clean so the equation isn't so simple. Where hydroelectricity is concerned, reducing consumption limits demand in an effort to reduce the need to construct additional dams or power plants in the future, rather than reducing emissions now.
Our utility now does not have 'hydro' in its name and I was curious as to our current source of power. So I did some research and found some data for our zip code, which I've graphed:
So, in California, the link between turning off the lights and minimizing my footprint is more obvious, along with the fact that my footprint is probably larger here given the mix of energy sources. About 75% of the pie is non-renewable and fossil fuels make up more than half of the non-renewable energy sources, while the remaining piece is nuclear. Long story short, the pie is neither sustainable nor appetizing. Here's hoping that the recipe is tweaked sooner than later.
