DESIGNS ON DECARBONIZATION

The initiative to stop providing natural gas hookups takes place within a broader strategy of decarbonization, which shifts domestic energy use away from fossil fuels like oil and natural gas. While some may be able to consider alternatives like geothermal systems, many users and their equipment would typically rely on electricity instead. (Thus, decarbonization and electrification are terms commonly used interchangeably in some energy conversations.)

Heating plays a significant role in overall energy consumption. Existing building stock includes many gas-reliant units that will remain in service for years. Not too much can be done about that, so decarbonization advocates see stopping the flow of new gas appliance installations as the most straightforward step toward curtailing fossil fuel use.

Greater reliance on electricity, however, is not an end in and of itself. Electrification only pays off if the electric grid is supported by an increasing share of renewable energy sources such as solar and wind energy. In that scenario, the thought goes, the result would be a markedly more sustainable energy landscape for the U.S.

CITY TO CITY

Unlike the potential comprehensive national HFC phasedown strategy, reducing or eliminating natural gas connections is more of a piecemeal proposition. Multiple jurisdictions passed some sort of measure on the matter last year, with some of those taking effect as early as this year.

Several New England states have joined California in establishing comprehensive decarbonization targets, setting aggressive goals for 2050. In Massachusetts, Brookline took the lead among localities, barring new construction from using either oil or gas as of 2021.

Elsewhere in that state, Concord is considering its own plan for moving the entire city’s energy use to renewables. Its renewable energy strategy reflects the multifaceted reality of the task, looking for advances in transportation and overall electricity use as well as heating and cooling.

In California, Berkeley moved first last year with a local ban on natural gas hookups. Approximately 20 localities have done similarly around the state regarding new construction, although differences in substance and timing exist from restriction to restriction. Some don’t ban natural gas infrastructure outright but allow its use conditionally, depending on a building’s overall efficiency.

San Jose passed a ban that applied to residential but not yet to commercial buildings. In that case, the city is pursuing an existing net zero goal for new residential as of this year and for commercial buildings by 2030.

While San Jose’s measure passed unanimously and Berkeley’s decision was met with applause by those in attendance, things don’t always proceed so smoothly. In Seattle, a proposed ban on natural gas hookups in both commercial and residential new stock received sufficient opposition to prevent approval.

Nevertheless, Seattle Mayor Jenny A. Durkin issued a recent executive order eliminating fossil fuel systems in “every new or substantially altered municipal building” starting in 2021.

FEELING THE PINCH

In the 1970s, President Gerald R. Ford’s administration incentivized development of energy sources other than natural gas and oil, and it proposed increased taxes on imported gas to conserve fuel. That era had sufficient pipeline capacity but suffered from a shortage of natural gas itself.

Now, the U.S. enjoys fairly abundant natural gas resources, but some regions are experiencing trouble meeting demand with existing pipeline capacity. Steve Goreham wrote an article for the Master Resource website mentioning some eye-opening developments in the Northeast last year.

“Con Edison announced a moratorium on new natural gas customers in Westchester County, New York,” he wrote, adding that a Massachusetts utility also announced “it can no longer accept new natural gas service requests due to a lack of supply.”

Last summer, New York utility National Grid responded to lack of progress on a proposed new pipeline by ceasing new hookups altogether in Queens, Long Island, and Brooklyn.

Pipeline-related environmental objections, opposition to fracking, and general climate change concerns all contribute to the rockier terrain surrounding the creation of new capacity these days, separate from any other logistical or financial hurdles such projects might face.

CONTRACTOR IMPACT

ACCA responded to an invitation to comment by reiterating its support for preserving choices for homeowners and equipment availability for contractors, regardless of fuel type.

Todd Washam, the association’s vice president of public policy and industry relations, suggested that the concerns underlying some natural gas opposition might be better redirected.

“If policymakers and environmentalists are so concerned about efficiency and carbonization, then they need to start working on solutions for proper installation practices so that the equipment that we have today — the high-end, very efficient equipment — is going to work as it was designed to work.”

Washam also highlighted a specific intersection of contractor relevance and this piece of electrification strategy: Some HVAC contractors also work as fuel oil or propane dealers. He said he knew of several in the Washington area.

Contractors do the same in other areas without access to natural gas, and/or in areas where homeowners have traditionally dealt with more extreme winters by having primary and secondary heating systems.

TUG OF WAR

New ordinances and pipeline shortages are creating a scattered but still relatively sudden inability to get a natural gas hookup where it previously had been available. Pushback will likely continue from the natural gas and propane industries, among others. Back in Berkeley, the restaurant industry has filed a lawsuit challenging that city’s ban as it fights for the right to keep cooking with gas.

Meanwhile, simple energy demand for restaurant stoves and everything else veers upward. BP’s “Statistical Review of World Energy” reported that global energy consumption increased at a rate of 2.9 percent in 2018, “almost double its 10-year average.”

While renewable sources continue to develop at a relatively strong pace according to the study, natural gas topped global growth in energy consumption, rising at a quick 5.3 percent clip led by demand in the U.S.
