Food, Inc.
by
The Obamas put in the first food garden (organic, natch) on the White House grounds since Eleanor Roosevelt's victory garden during World War II. We dig that.
Skeptics may scoff that's it just symbolic, but I don't think so.
Efficient Cooking
by
Electric ranges may actually be more efficient than gas ranges.
Which is better: a gas or electric range? Most serious cooks prefer gas, because it delivers heat instantly and is highly controllable. With typical electric cooktops, it takes longer for the burner to respond when turned on and when the setting is adjusted.

You can achieve the Water Efficient Landscaping credit simply by eliminating turf grass, planting native and adaptive species, and not installing an irrigation system. If those measures go too far for your project, you can still achieve the credit as long as you have some flexibility with plant species selection, and irrigation system design and controls.
Air-Source Heat Pumps
by
The Hallowell Acadia heat pump can operate at temperatures below 0 degrees and still perform significantly better than electric-resistance heat.
Last week's column looked at efficient but also very expensive ground-source heat pumps; this week we'll look at a less expensive option that's becoming more common even in our climate: air-source heat pumps.

The ClimateMaster ground-source heat pump is recognized by the GreenSpec directory as a green product.
Last week I introduced heat pumps and described how they can deliver more heat than is contained in the electricity they consume--while being able to provide cooling as well as heating. I mentioned two different types of heat pumps: air-source and ground-source. This week I'll cover ground-source (also known as "geothermal" and "geo-exchange") heat pumps.
Grow Clean Air!
by
The myth that plants will clean the air is a seductive one: if true, we could fix indoor air quality problems without expensive changes to mechanical systems and without worrying about what materials we introduce to the indoor environment.
There is scientific evidence that plants clean the air, pulling formaldehyde and other pollutants out of the air and turning CO2 to oxygen (after all, this is what trees and outdoor plants do for the earth).
