Our new relationship with electricity: How Span.IO and Quilt aim to give homeowners control

In 2023, the movement for mass electrification has come home (literally). Gas-fired stoves and heating systems are under fire for carbon emissions. Heat pumps, lauded as the future of HVAC, have become a trendy technology (and political litmus test). Homeowners with solar can in some areas sell excess energy back to the grid operator. To help Americans afford cleaner devices, the Inflation Reduction Act (IRA) provides significant tax credits for solar panels, battery storage systems, upgraded electric panels, induction stoves, and electric vehicles. 

So how will those forces driving home electrification  alter the way consumers manage their electricity consumption and invest in new technologies to make that easier?  

The SOSV Climate Tech Summit (Sept 26-27 / free & virtual) hosted two entrepreneurs focused on this electrified future of the home. We got their take on the state of electrification and further innovations and policies needed to cut the gas lines for good. 

The IEA estimates that to achieve net-zero emissions by 2050, electricity needs to be decarbonized by 2040 and account for half of total energy consumption, up from 19% in 2018. To make matters more difficult, there may be an additional 2 billion people on Earth by 2050, and rising living standards in the Global South (check out the panel) will increase per capita energy demand. Mass electrification won’t count for much unless the whole world—not just wealthy, climate-conscious consumers—get on board.        

This panel featured two companies on the forefront of home energy management and electrified cooling and heating.  

SPAN’s smart electrical Panel enables homeowners to manage and reduce energy costs, circuit by circuit, via  a smartphone app. The company also provides Drive, a smart EV charging system that minimizes energy usage and costs, and an energy backup technology that extends the life of battery systems by 40% on average according to SPAN. The company has raised over $230M from backers including Wellington Management, Congruent Ventures, Capricorn Investment Group, Qualcomm Ventures, Fifth WallMunich Re Ventures, A/O PropTech, and Amazon’s Alexa Fund. SPAN founder and CEO Arch Rao joined the discussion.

Quilt, founded by three former Googlers, is developing next-gen, ductless heat pumps that are easy on the eyes, cheap to install, and optimized for energy efficiency by an AI. In May 2023, Quilt raised a $9M seed round led by Lowercarbon Capital and Gradient Ventures with Incite Ventures, MCJ Collective, Garage Capital, Climate Capital, and Spacecadet participating. Quilt currently has a waitlist for its product, set to launch sometime in 2024. Paul Lambert, CEO and founder of Quilt, joined the panel.

Emily Pontecorvo, Founding Staff Writer at Heatmap News, moderated this discussion.
