The Massachusetts Department of Public Utilities has taken a significant step by issuing an order to transition the building sector off natural gas to meet greenhouse gas reduction mandates. While natural gas has been the primary fuel for heating in Massachusetts due to its low cost, this is changing rapidly as gas heating bills are expected to double within a decade. The shift is driven by the realization that heating with gas is actually worse for the climate due to methane leaks in the distribution system. Clean, renewable energy options like cold climate heat pumps are gaining traction, with successful implementations in Massachusetts and colder climates like Maine. The decreasing cost of clean energy and the increasing cost of gas heating are driving this transition. Additionally, the state's electric grid is already delivering almost 30% renewable energy, with advancements like a utility-developed geothermal system in Framingham. Despite promises from gas companies to introduce 'cleaner' gases like renewable natural gas (RNG) and hydrogen, these alternatives have been criticized for high costs, limited availability, and minimal emissions impact. Experts question the viability of these options and advocate for a transition to truly clean energy sources. This transition is not only environmentally beneficial, but it is also projected to create over 123,000 new jobs in the Northeast, offering opportunities for various skilled workers. Legislation like The Future of Clean Heat Act is proposed to facilitate this transition by removing legal barriers for gas companies to provide clean heat and aligning utility plans with emissions reduction mandates. The article emphasizes the urgent need for the Legislature to mandate this transition, as delays will only make the process more challenging and costly. The shift towards clean energy not only benefits the environment but also presents an opportunity to boost the economy and create sustainable jobs in Massachusetts.
