This year we were determined to cut our usage as much as possible so rather that depending on the built in thermostats on the air conditioners, we actively monitored our comfort and turned the window units off when we weren't in the the room and at night.
We also built a clothes line and utilized it as often weather permitted. The clothes line consists of a pulley attached to the house just off the front porch and another mounted fifty or sixty feet across the yard on a post, with a nylon rope looped between. It's very convenient and we can hang or retrieve the laundry without ever leaving the porch.2008 was a very hot summer, but not the worst we've ever had by any stretch. Oil prices were up for an extended period last summer too, so we're aware that some of the money we've saved this year are not just due to our conservation efforts. We really worked at becoming more aware of our power consumption.
Our power bill contains a graph showing the last thirteen months of usage as well as exact usage for the current billing period and twelve months ago. I am pleased to report that for the past three or four months, our usage compared with the same period last year was drastically lower. On our most recent bill, covering the period from 9/11/09 to 10/12/09, our usage was 817 kW/h, a great improvement compared to the same period twelve months ago, when our usage was 1606 kW/h.
The point is that it's not that hard to conserve energy if you simply practice mindfulness. You don't have to sit around in the dark, or sweat through each night in discomfort to make a big difference in your power consumption. Keeping your awareness focused on eliminating waste, like turning the air conditioner down or off when you won't be home to enjoy it, or hanging your laundry instead of running the clothes dryer for an hour can really make a difference in your power bill and your bank account. More important, it makes a big difference in our dependence on dirty coal and foreign oil used to generate most of our electrical needs, thus reducing the need for more mountaintop destruction and global resource wars.
Many in the peak oil community doubt that renewable energy sources can ever provide all of our nation's power needs, and at current levels of usage, I would have to agree. But if we're mindful of our consumption I believe that in the long run we can reduce our electrical needs enough that renewable energy, especially point of use generation, will become viable means of replacing our current, unsustainable power grid.
