To wrap up my ode to John Henry (and a more sustainable lifestyle) I am going to cover a few more everyday household plug-ins by giving the current ON the grid offering, it’s OFF the grid alternative, and weigh in on whether a switch is warranted.
ON
The Fridge: We all know what it does and why we use it–so what are the OFF the grid alternatives?
OFF
The Fridge: William “The Refrigerator” Perry, former defensive lineman for my beloved 1985 Super Bowl Champion Chicago Bears. You could try contacting him to see if he’ll deliver fresh food to your door on a daily basis. I understand he’s not very busy these days.
OFF
Jarring and canning fruits and vegetables to preserve for the winter months may save some space in the fridge, but cannot replace the fridge altogether.
SWITCH?
Realistically, it’s not likely. However, the size of refrigerators in this country is insane. My parents have an enormous fridge and regularly come across 3 year old cheeses and meats that get lost under piles of their newer/fresher replacements. In lieu of a switch to William Perry (we can’t all use him–it’s simply unrealistic) we can buy a smaller, energy efficient fridge, fill it with less food (eat fresher food), and keep the door open for very short intervals (know what you’re getting before you open it). A few generations back, families typically had more members yet much smaller fridges, so it can be done–and you’ll benefit from fresher fare.

I don’t know how you spent your weekend, but we spent ours with hands outstretched, feeling for hot, attic air shooting out of electrical outlets, ventilation fans and air vents. After months of crazy-high electric bills, we decided to get to the bottom of why it was costing so darn much to cool our rather small home.
Enter the HERS Rater (Home Energy Rating System).
It turns out there are wonderful people who will come to your home, put up a strange looking contraption called a “blower door” on either your front door or entry to the attached garage. A fan is turned on, the pressure is measured (our house was brought to -50 Pascals) and the cubic feet per minute of air that is rushing out of the house is measured.
Author’s note: the following article on home heating is the third in an eight-part series. This article addresses climate conditions found in the San Francisco Bay Area, but may have applicability elsewhere.
Forced air systems are the most common heating systems in California and are used in most new construction elsewhere. They have two big advantages: they are cheap to install, and they provide heat at a moment’s notice. Having “instant-on” heat is vital for intermittent use spaces like ski cabins. Otherwise, forced air is the least energy efficient and least comfortable way of heating a typical home. Why?
Ventilation and Heat Loss
For the health and well-being of its occupants, a home must exhaust stale air and refresh it with new air drawn from outdoors. Forced air systems heat and blow this air, via ducts, throughout your house. Since new air is continually entering and leaving, you are heating the outdoors.
On April 4th, the architecture and planning firm of Weber + Thompson will move into its new headquarters, located at the intersection of Thomas Street and Terry Avenue in the South Lake Union neighborhood of downtown Seattle.
The firm sees its new headquarters as an emblem of its sustainable approach to architecture. The most innovative feature of the building is its passive cooling design; the building will not be air conditioned at all.
