While there’s huge, expensive projects you can undertake to cut these factors, there’s two simple things we did which cut our impact roughly by a quarter.
Below is a picture of our “new” (1980s) home gas use (we’re the blue line). In October things started to cool off here and you’ll notice we were running at the same gas use of an “efficient” neighbor, but since then we did just the two improvements below and now use 26% less natural gas than an “efficient” neighbor.Continue reading
