Stephen Hren

Stephen Hren is a restoration carpenter, builder and teacher who specializes in sustainable design and passive and active solar heating technologies. He was inspired to write about those who “seek forgiveness rather than asking permission” after his off-grid cob home came to the attention of the local tax assessor, triggering a lengthy and painstaking after-the-fact inspection process. Along the way Stephen has helped to start a local food co-op and an edible landscaping collective, and retrofitted an existing home to not use any fossil fuels. He is the co-author of The Carbon-Free Home and A Solar Buyer's Guide for the Home and Office.
