EnergyEnergy plays an essential role in all aspects of a community, whether it’s the gas and electricity we consume directly in offices and homes or that which we consume indirectly in the air conditioning systems in shops and the streetlights that illuminate our paths at night. Choices about how and when to use energy are ways that individual community members can impact total energy use.

Review Longmont’s Greenhouse Gas Reduction Report.

100% Renewable Energy Resolution

On January 9th, 2018, City Council passed a resolution to commit Longmont to 100% renewable energy supply for electricity supply by 2030. Sustainability staff will be working with Longmont Power & Communications and Platte River Power Authority to make this goal possible.  

As part of this commitment, the City will develop a Just Transition Plan that engages and works with low-income households and marginalized communities to develop a more equitable transition to 100% renewable electricity.

What is Longmont’s current renewable energy supply?

Approximately 30% of Longmont’s electricity supply came from renewable energy in 2017 – including hydro, wind and solar.
