Who we are - What we do

Welcome to the Middle Tennessee Chapter of the Sierra Club! We are an active local group, made up of volunteers dedicated to exploring, preserving and sharing the beauty of our nation's and Tennessee’s wild spaces.

Nationwide, Sierra Club members and supporters are made up of more than 1.3 million people, just like you. We are the largest and most influential grassroots environmental organization in the United States. Come dream, discuss and discover with us. Together we can make a real difference for today and into the future.


We are outdoor enthusiasts, exploring and protecting all that Tennessee has to offer. Together we host group hikes, floats, informative monthly programs and group outings and provide our community with environmental education programs, legislative support, and opportunities to learn from and share our love of the outdoors.

CRITICAL TENNESSEE VALLEY AUTHORITY (TVA) BOARD MEETING: August 21, 2015 (Friday) – Come to the TVA Board Meeting in Knoxville to show TVA that Tennessee wants to maximize solar and wind power and energy efficiency in the next five years to protect health, clean our air and water, lower utility bills, and slow climate change! We want a BIG TURNOUT for the public comment session and press event. You are asked to arrive at 8:00 a.m. Free transportation will be available from the Nashville area either Thursday evening or Friday morning. Participants are asked to wear business attire, white shirt if possible.

At the meeting, the TVA board of directors will be voting to approve TVA’s long-term energy plan, which will set the course for how TVA will generate energy for the next 20 years.
