Detroit’s Bright Idea: How One Startup is Cutting the Cost of Green Homes

The Problem: Efficiency Upgrades Are Too Damn Expensive
Why homeowners keep putting off fixes that save money
Let’s be real: nobody gets excited about attic insulation or a new HVAC system. But here’s the kicker—these upgrades can slash energy bills by 30% or more. The problem? The upfront cost makes most homeowners balk. A $10,000 heat pump might pay for itself in five years, but try explaining that to someone living paycheck to paycheck.
Enter Radiant, a Detroit-based startup that’s flipping the script. Instead of begging banks for loans or waiting for government subsidies, they’re cutting deals with utility companies. The pitch? Utilities already waste billions propping up aging grids during peak demand. What if they just paid to make homes more efficient instead?
The Utility Playbook
How Radiant turned power companies into unlikely allies
Radiant’s founder, Marcus Boone, spent years in energy consulting before realizing utilities were sitting on a goldmine of demand-side data. 'They know exactly which neighborhoods overload transformers on hot days,' he says. 'We showed them it’s cheaper to insulate 100 homes than build a new substation.'
The math works like this: For every dollar utilities invest in efficiency upgrades, they save $2.50 in avoided infrastructure costs. Radiant’s pilot with DTE Energy in Michigan wrapped 1,200 homes in better insulation last winter—and peak demand dropped by 8% in those areas. That’s the kind of number that makes CFOs sit up straight.
The Ripple Effect
From lower bills to union jobs
This isn’t just about kilowatt-hours. Radiant’s model requires local contractors to do the installations, and Boone insists on union-scale wages. In a city where 30% of residents live below the poverty line, that’s intentional. 'We’re not parachuting in Silicon Valley solutions,' he says. 'Detroiters should own this transition.'
The environmental justice angle is hard to ignore. Low-income neighborhoods often have the leakiest homes and highest energy burdens. Fix that, and you’re not just cutting carbon—you’re putting real money back in people’s pockets. One homeowner, Lydia Carter, saw her January gas bill drop from $280 to $90 after Radiant’s upgrades. 'That’s groceries for two weeks,' she says.
The Bigger Fight
Why utilities might kill this in the crib
Not every power company is lining up to embrace Radiant’s model. Some still make guaranteed profits on infrastructure projects—a holdover from the monopoly era. 'There’s a cultural inertia,' admits Boone. 'You’re asking engineers who’ve built power lines for 30 years to think differently.'
Then there’s the political minefield. In states like Texas, where deregulation favors gas plants, efficiency programs get labeled as 'government overreach.' Radiant’s next move? Partner with cities to bundle upgrades into property tax assessments. 'If utilities won’t play ball,' Boone says, 'we’ll find another way.'
The Bottom Line
This isn’t just about Detroit
Radiant’s approach could rewrite the playbook for the $30B home efficiency industry. If scaled nationally, the EPA estimates similar programs could cut U.S. residential emissions by 15%—equivalent to taking 20 million cars off the road.
But the real test is whether Boone can turn a clever idea into a movement. 'Utilities hate risk,' he says. 'Our job is to prove this works so well, they’d be stupid not to do it.' For anyone tired of waiting for Congress to act on climate, that’s a rallying cry worth hearing.
