# Gregg Semler

> Gregg Semler is the founder and CEO of InPipe Energy, a Portland-based company that generates clean, around-the-clock electricity from the water already flowing through municipal pipelines. A serial clean-energy entrepreneur since 2000, he previously led PolyFuel, ClearEdge Power, and Lucid Energy, and spent years as a venture investor in the sustainable economy. His pitch is contrarian: instead of covering the planet with solar panels and batteries, harvest the predictable, weather-proof energy hiding in the millions of miles of pressurized pipe that move our drinking water.
