Ending the use of fossil fuels to heat homes and buildings is a key challenge for cities hoping to achieve net-zero emissions. Nowhere is that more evident than in Philadelphia, where technical and financial hurdles and a reluctant gas company stand in the way of decarbonization.
In 1836, Philadelphians mostly used whale oil and candles to light their homes and businesses. That year, the newly formed Philadelphia Gas Works caused a stir when it lit 46 downtown street lamps with gas made from coal in its plant on the Schuylkill River. By the end of the Civil War, public thoroughfares and private dwellings in the core of most large Eastern cities were illuminated by gas, supplied through cast iron pipes buried beneath the busy streets — and the whale oil lighting industry was nearly dead.
Philadelphia’s own pipe network has expanded over the past 185 years to encompass 6,000 miles of gas mains and service lines. But today, Philadelphia Gas Works (PGW) — the largest municipal gas utility in the country — is the incumbent business staring down existential threats, facing challenges from new technologies, upstart rivals, and a quickening 21st-century energy transition that aims to convert many buildings from gas to electricity.
In recognition of these forces and the city’s own climate action plan, Philadelphia has commissioned a “diversification study” to find a new low-carbon business model for the nation’s oldest gas utility, which delivers natural gas to 510,000 customers.
Earlier this year, Philadelphia announced a target of achieving net-zero greenhouse gas emissions by 2050. “There’s just no way that can happen without PGW changing,” said Tom Shuster, clean energy program director of the Sierra Club’s Pennsylvania chapter, which advocates for wider building electrification. Gas sold by the utility is the single biggest source of the city’s climate-warming pollution, accounting for 22 percent of its greenhouse gas emissions…
