The Energy Resource Center

Energy Resource Center is a non-profit construction company assisting income-qualified families through energy efficiency improvements. Work completed includes insulation, HVAC, hot water heaters, lighting, appliances, air sealing and more. These efforts save money on energy bills, reduce demand on natural resources by cutting energy waste, assist with the affordable housing crisis, and create a safe environment in which Colorado residents can thrive.

Support the ERC


We rely heavily on donations from generous individuals and business owners in the region to support our programs.

Free Services


We offer free home energy audits and weatherization assistance to income-qualified homeowners and renters.

Pay It Forward


Purchase an energy audit or energy upgrades from ERC and a portion of your fees will go to help families in need.

Life doesn’t ask permission

When times get tough, our neighbors deserve an ally that eases their home energy struggles so they can stop worrying and get back to living.

According to statistics from Colorado State University, if Americans used 30% less energy in their homes, 450 power plants across the country would not be needed. ERC services help by cutting energy waste in every home served.
