As a way of celebrating Earth Day today, I've taken inventory of how much "greener" we, as a family, are this year compared to last.
The biggest greening has come from our moving into a new home that's only a mile from my office. Not only has my daily commute shrunk from 59 miles to 2 miles, with all the carbon emission reductions that come from not having to lug my butt those 285 miles to work each week, but the house we live in now is greener, too.
Our old house was in a nice sunny neighborhood in Campbell (outside San Jose), but there was no topography to speak of. We were in a flatlands surrounded by other houses/condos/businesses, and the micro-climate of our area meant we consistently ran temperatures 10 degrees warmer than other towns around us (love those
Bay Area microclimates!). Lots of trees in our neighborhood, including two huge camphor trees in our front yard, but that didn't mean it was any less hot in the summers. To help cope with the heat in our old place, we had air conditioning installed when we replaced the ancient furnace with a new energy-efficient one. While we lived more comfortably, we paid for it in our energy bills. The Springs and Autumns were the cheapest since we didn't have to pay to heat or cool the place, but we got used to shelling out over $200 a month in energy costs.
Flash forward to this year in our new home. We now live on the slope of a hill overlooking downtown Redwood City which means we get gentle breezes every afternoon and can leave the windows open most of the spring and summer to enjoy the natural cooling. Not only is the location of our home more conducive to natural climate control, but we have solar panels on the roof and an electric meter that spins both ways: when the panels generate more energy than we use, we feed back into the grid. At night and on cloudy days, we pull from the grid since the panels aren't generating anything. These solar panels have had an amazing impact on our electricity bill. Since we moved in last August, we've consumed
less than $200 TOTAL electricity (compared with
$200 a month in the old place). Wow.
The house we're in now is about 1,100 square feet bigger than our old home, to boot, but thanks to a dual zone furnace, we only heat the upstairs floor (where we spend 95% of our time living) and leave the well-insulated downstairs floor to its own devices.
There are other things we can do to get greener by next Earth Day, like cutting water consumption, growing our own veggies and my walking/biking to work several days a week (oh, and raising chickens!), but we've made huge strides in the last year. Here's hoping more and more of us can have similar impacts in lessening our footprint on the earth.
Happy Earth Day!
