Cutting energy consumption in the last energy crisis
People heating with oil in Massachusetts in 1978 to 1981 faced dramatic price increases. Many apparently sacrificed home comfort to control their heating bills.
How much is the efficiency of the existing housing stock improving?
Efficiency efforts have been successful over time, especially in the period after the oil price shock, but steadily through the decades.
Housing Quantity
Homes have been getting larger for decades. Data from compiiled MassGIS gives a clear view of the pace of growth.

This post attempts to summarize the environmental and consumer considerations for people seeking to electrify heating in a home.
