Houston is the Energy Capital of the World — and the Climate Capital too.

HECW brings together the builders and backers of the energy transition in the city that powers America. No other city can claim Space City, Energy Capital, Medical Center, and AI frontier all at once.

5,000+ attendees. 150+ speakers. 250+ organizations. Two years running.

Houston Energy & Climate Week has rapidly become the premier convening for energy and climate innovation in the South — drawing Fortune 500 companies, startups, nonprofits, government, academia, and community leaders.

The future isn't either/or. Houston made it both.

HECW was founded on the belief that energy security and climate action are not opposites — they are partners. The Power of & is our thesis: builders AND backers, innovation AND community, ambition AND accountability.

Year 3 — September 13–18, 2026. Back to the Future.

The 2026 theme celebrates Houston's role as the city that keeps arriving early. From geothermal to AI, from Space City to the Medical Center, Houston is already living in the future. Come see it.

HECW is community-powered.

Every event, every sponsor, every volunteer makes HECW possible. The week is built by and for the Houston community — not a conference, but a movement.
