The gas pipeline from PA to New England was never going to pencil out. The actual cost savings is tiny relative to the capital required to build and maintain such a pipeline (basically the most expensive real estate per-mile in pipeline history).

The price differential between New England and the rest of the country is not much, it spikes right now as both Europe and New England share climate conditions, and is exacerbated by Putin/Ukraine.

New England is going to have some of the highest energy demand per square foot (note: not household) in the continental US due to the realities of: average oldest buildings, highest density most northern settled area, and the most days requiring moderate to heavy indoor temperate adjustment in the U.S.

In New England, the absolute best improvement people can make is insulation, heat pump retrofits, upgrade lights/appliances, and solar/geothermal systems.

Subsidizing wasting more energy is not a good idea, regardless of how you feel about “green” tech.
