California needs an equitable emissions reduction strategy. If we are to reach the state’s policy objectives, a building decarbonization strategy must be robust enough to enable the participation of California’s low- and moderate-income (LMI) and renter households, who together represent more than 40 percent of the state’s population. The Building Decarbonization Coalition launched the Accessible Financing Project to address these barriers and expand access to clean energy upgrades with a combination of funding and financing.

Rural, economically-distressed areas across North Carolina consist heavily of low-income residents who face high levels of energy burden. Energy burden, or the share of income spent on energy bills, limits what households can spend on other necessities such as food, medical supplies, and transportation. High energy burden often results when a dwelling lacks proper air sealing, insulation, and maintained equipment. Residents facing high energy burden can face greater health risks such as reduced air quality, mold, and pest infestations. In 2015, REC launched its energy efficiency program Upgrade to $ave to offer relief to member-owners facing high energy bills.

PAYS for Clean Transport reduces the upfront cost of electric vehicles, starting with transit buses, by harnessing a utility’s capacity to invest in on-board batteries and recover its cost as a service charge. In the cities that implement it, the mechanism can lower costs of rapid transit, while completely eliminating tailpipe emissions from transit buses.

For years, utilities have resisted the distributed energy revolution already underway. Yet, electrification of the transportation sector presents a historic opportunity for growth, and it is a critical path for climate stabilization. What’s new? In the last year, plummeting battery costs have helped the some vehicles — specifically, long-range electric transit buses — finally approach cost parity on a lifecycle basis when compared to diesel buses. At the same time, an innovative finance mechanism is gaining traction in the utility sector that would allow utilities to invest and recover costs for the on-board batteries. With these developments, utilities could drop the upfront cost of all-electric vehicles, set off a surge in sales, and rapidly capture the prize of market share for transportation fuels. But will they?
