The Mayor’s Office of Sustainability's (OS) fourth Solarize Louisville campaign is a wrap. We are happy to announce this year was our best yet. A heartfelt thank you to our program installers, Daily Green Power and Pure Power Solar, for making the work happen.
-
Contracts: Solarize ‘25 produced a record 89 contracts in the amount of $3,389,846.00
- Coverage: 1,115 kW worth of panels installed, a generation capacity offsets ~1,220 metric tons of CO2 per year, or the equivalent taking ~265 cars off the road, or planting ~55,000 trees
- Storage: 36 battery systems were placed into service, with 719.7 kWh in storage capacity
Though the sunset of residential solar tax credits (December 31, 2025) and changing market conditions are likely to impact Solarize Louisville moving forward, the program will return for a 5th campaign, and we will be excited to share more with the community on its structure in the coming months!

dbird Days infographic
Each spring and fall, millions of birds migrate at night. Many perish due to collisions with buildings and windows caused by artificial lighting. This issue results in billions of bird fatalities and injuries annually in the U.S., including in Louisville.
The Louisville Audubon Society’s Lights Out Louisville program, in partnership with OS and Parks and Recreation, organized dBird* Days to collect critical data on bird collisions, protect migrating birds, and prevent bird deaths through community advocacy.
By the numbers:
- 5 dBird days hosted
- 45 dbirds collected
- 68 volunteers**
*dBird is an online crowd-sourced data collection tool that provides a way for the public to report incidents of dead and injured birds, helping to contextualize and guide research and advocacy efforts thataim to reduce human-caused hazards to birds.
**Volunteers across all five days.

The OS team took a trip out to Jefferson Memorial Forest for team building and much needed time in nature. Fall is a great time to hike around Louisville with cool temps and colorful fall foliage.
Thank you to our guides, John and Autumn from the Natural Areas Division of Louisville Parks & Rec, for teaching us about conservation and being open to incorporating new sustainability initiatives!
Over the holidays as you celebrate with family and friends, conservation can take a back seat to other more pressing matters (like eating pie and opening presents), so we want to give you a quick reminder on how to be as sustainable as you can during this holiday season. Here are a few tips that you can easily integrate into your holiday routine:
- When you’re unwrapping gifts, make a pile of all the discarded wrappings so it’s easily brought to the recycling bin once you’re finished.
- Instead of sending uneaten food scraps to the landfill, compost them!
- To reduce waste & give responsibly, gift an experience and provide someone with a memory they won’t forget.

A recent study found that 92% of Americans would rather receive an experience than a physical gift. It can be something as simple as a local dinner or tickets to a show.
Fill out the survey to share your thoughts on data centers in Louisville.
Recently, LG&E received approval from the Public Service Commission (PSC) to construct two new gas-operated power plants to accommodate projected data center growth in and around Louisville.
In anticipation of that data center growth, Metro Council has tasked the Office of Planning (OP) with drafting zoning regulations specifically for data centers. OP held various public meetings in late October/early November and currently have a survey open for public comment.
The OS has been working closely with OP on drafting these regulations to ensure responsible data center development within Louisville Metro.
Help protect vacant and unsecured buildings from hazards this winter.
As the colder months approach, vacant properties in our neighborhoods face a higher risk of crime, fires, break-ins, and other safety hazards. Unsecured buildings can threaten the safety of our entire community. The Department of Codes and Regulations urges residents and property owners to act now so we can protect our community together.
Property owners are required to keep vacant properties clean and secure to prevent emergencies and stay compliant with city codes. Taking proactive steps now helps avoid costly incidents and keeps everyone safer as temperatures drop.
If you have concerns regarding a vacant or abandoned property, or require guidance in securing your own, please contact our office at (502) 574-2508. Your help plays a vital role in maintaining safe and healthy neighborhoods throughout the winter season.
Let's join forces to freeze out fire risk and protect our community - your action matters!
