Beyond NFTs: 11 Practical Blockchain Applications Shaping Our Future

7. Energy Grid Management

Imagine selling your rooftop solar power straight to your neighbor—no middleman utility marking up the price. That’s what peer-to-peer energy markets like Brooklyn Microgrid, powered by LO3 Energy, do using blockchain. Every watt gets logged; you can see who made it, who bought it, and prove it came from a real renewable source. Test neighborhoods using these systems saw billing accuracy and monthly savings go up, plus more homegrown green energy. It all sounds futuristic, but there are real hurdles: old infrastructure, utility companies not eager to change, and questions about scaling up. Still, if you want cheaper, cleaner power and more control, these experiments point the way.
