Holiday Reflections On Living Smaller, Living Lighter

Observing the obsessions of most people during this season that seems to revolve almost exclusively around consumption, the simple ideas of living smaller and living lighter on our environment might appear almost sacrilegious. Last weekend, I had the opportunity to visit a local big-box retailer to pick up a couple of modest items.

An oversized furnace is a very wasteful shortcut taken by many LEED homebuilders and HVAC service providers. The result is that many unsuspecting homeowners are straddled with an appliance that overly dries their indoor air, wastes copious energy, and sends a lot of money right up the chimney.

Sustainable Food: Food Myths Busted

Sustainable Foods Under Attack Big Agribusiness loves to throw around dire predictions of impending world hunger.

The Kill A Watt Energy Meter: A green gadget lover’s dream

The Kill A Watt Energy Meter is a simple and remarkably useful device for revealing how much appliances are costing you to operate. A few experiments with one of these meters have saved me hundreds of dollars in energy waste and hundreds more in unnecessary appliance upgrades that I probably otherwise would have made. A while back, I was ready to replace our ten year old upright freezer with a new energy efficient freezer. I assumed that, given the age…
