Energy Efficiency

As a city located in one of the top coal-producing states, Louisville's electricity is primarily generated by coal-fueled power plants. As a result, Louisville's energy rates are among the lowest in the nation. Even with low utility costs, Louisville Metro Government encourages the community to pursue energy efficiency, energy conservation and renewable energy options. These efforts help improve Louisville's air quality, provide cost savings for users, and reduce the city's contribution to climate change. 


Residential Energy Efficiency

Residents can conserve energy through one or all of the following programs:

  • Louisville Gas and Electric Programs
    • When you sign up for LG&E's Demand Conservation program, LG&E will install a device on your central air conditioner, electric water heater or heat pump that will reduce your energy demand during peak hours. In return for signing up, LG&E will credit your utility bills. Credit amounts start at $2 per month and vary according to the type of home. 
    • The LG&E Green Energy Program asks participants to contribute $5 per month to help regional renewable energy operators offset the higher cost of sustainable electric generation. 
    • LG&E offers an Advanced Meter Program, which allows residents and commercial customers to view their electricity usage online. This program is only available to the first 5,000 customers who subscribe.

  • Other Weatherization Programs
    • Louisville Metro Government's Weatherization Assistance Program provides financial assistance to low-income residents of Metro Louisville to make energy conservation improvements to their homes. Households assisted can either own or rent the dwelling, although renters must have the approval and cooperation of the property owner. To inquire about the Weatherization Assistance Program, please call 574-5850. 
    • Volunteer with, or sign up to receive free weatherization services from Project Warm, a local nonprofit group that helps low-income homeowners prepare for winter weather. 
Non-Residential Energy Efficiency 
  • The Energy Project Assessmnet District (EPAD) Program is a unique financing mechanism that allows property owners to repay private loans for energy efficiency projects for nonprofits, commercial entities, and multifamily housing with five units or more.
  • The Louisville Energy Alliance challenges building owners and operators in Jefferson County and the surrounding areas to realize the benefits of energy efficiency by participating in the annual Kilowatt Crackdown. To participate, all building owners need to do is benchmark their facility’s energy use with Portfolio Manager (for buildings) or Energy Tracking Tool (for industrial plants) and make improvements over the contest period. Top honors will go to the most efficient buildings and the buildings making the greatest energy improvements, but all buildings will be recognized for participating and striving to improve their environment impact.
