Maximilian Obwexer

Founder & CEO, 21energy

CEO of 21energy, the Austrian company that turned Bitcoin mining into a heating system — with thousands of devices already warming homes across Europe while securing the network. Now partnered with one of Europe’s largest heating manufacturers to build a Bitcoin-powered central heating system designed to replace the continent’s millions of gas boilers. Bitcoin is not just the future of money — it’s how Europe will heat its homes, stabilize its grid, and reclaim energy sovereignty.

How Is Bitcoin Changing the Energy Game?

Learn how Bitcoin mining is turning "waste" into a gold mine, and how you can capitalize on the most significant infrastructure shift of the century.

Bitcoin is no longer just a consumer of energy — it's becoming a vital tool for grid stabilization and renewable energy development. This panel examines how Bitcoin is "changing the energy game" by incentivizing the build-out of stranded energy resources, reducing methane emissions, and providing the flexible load necessary for a modern and more resilient power grid.
