Brainstorm E will take place Sept. 28 – 29, 2015, in Austin, Texas.

Building upon the heritage of Brainstorm Green, long the leading summit on business and the environment, Fortune has transformed it into a new conference, Brainstorm E: Where Energy, Technology and Sustainability Meet. The new conference will still focus on business and sustainability but with a heightened emphasis on energy and technology and how the two are disrupting business models for companies in all industries. Says Brainstorm E co-chair and Fortune Assistant Managing Editor Brian O’Keefe: “The world is changing fast, and we wanted to make sure our conference reflects the cutting-edge of what’s occurring in the world of business.”

Brainstorm E is for leaders from a broad range of industries that are harnessing the power of energy, efficiency, and environmental innovation—including automakers, tech giants, basic materials and chemical producers, retailers, transport, water, and consumer products companies—along with the bankers, VCs and private equity firms that are financing this revolution.

Fortune also announced Monday that its 2015 Global Forum will take place in San Francisco Nov. 2 – 4. The event, which first kicked off in 1995, hosts CEOs of the world’s largest companies — the Fortune Global 500 — along with leaders in innovation and technology from emerging companies.

Next year’s Global Forum will focus on disruptive innovation and how best to use Silicon Valley’s entrepreneurs and technology to bring corporations around the world into the 21st century.

The last Global Forum took place in 2013 in Chengdu, China, and saw participation by over 100 top global CEOs, including Jamie Dimon of JPMorgan Chase, Bob Iger of Walt Disney, Jeff Immelt of General Electric and Muhtar Kent of Coca-Cola.

In October, the Most Powerful Women Summit in Laguna Niguel, Calif., drew some of the biggest names in business, including Facebook’s COO Sheryl Sandberg, General Motors CEO Mary Barra, Warren Buffett, Melinda Gates and IBM CEO Ginni Rometty. Fortune’s MPW: Next Generation conference is debuting this week in San Francisco, Calif.

In July, Fortune’s Brainstorm Tech conference took place in Aspen, Colo., featuring Microsoft’s Satya Nadella, Intel’s Renee James and Instagram’s Kevin Systrom. It returns to Aspen July 13 – 15, 2015.
