The Power of
The future isn't either/or. Houston made it both.
It all started on a flooded Houston lawn.

August 2018 — Mayor Turner meets Katie Mehnert on her lawn, one year after Harvey
When Hurricane Harvey tore through Houston in August 2017, Katie Mehnert watched floodwaters swallow her home and business. Evacuated by boat with her young daughter, she took to social media with a clarion call of anger, grief, and resolve — a voice that resonated with thousands across the city.
A year later, on the anniversary of Harvey's landfall, a remarkable conversation began — right back on that same lawn. Houston Mayor Sylvester Turner, a Democrat, and Katie, a Republican, stood together as political opposites united by a shared crisis. The discussion wasn't about partisan politics. It was about the future of Houston, the undisputed energy capital of the world — and the power of &: energy & climate, people & planet, oil & innovation.

"We need to bring everyone together across our city and the industry to drive the energy future for Houston."
— Mayor Sylvester Turner
Mayor Turner encouraged Katie to leverage everything she had built — her love for Houston, her deep roots in the energy workforce, and her ability to bring people together across divides — to champion this shared vision. He asked for her help and she made him a promise: she would.
A City Born by the Ampersand
The Ampersand Effect is what happens when you stop choosing sides and start building bridges.
Energy & climate. People & planet. Profit & purpose — not opposites, partners.
From the devastation of a hurricane, a new kind of storm was born: innovation, collaboration, and unstoppable progress.
