Does small wind energy or backyard wind turbines make sense? Why do we see so much rooftop solar, but so little rooftop wind? Bookmarks 00:00 Intro - Rooftop solar's domination in the urban renewables sector 00:38 Why don't we see more rooftop wind turbines? 01:38 Quality of solar resources - Solar irradiation in different places around the world 02:40 Quality of wind resources - Urban wind effects, wind shear effects, available power in wind 04:53 Available wind power in Kolding vs Canberra 05:40 Other points of comparison - Benefits gained from a rural location, noise and vibration issues, maintenance required 07:47 Applications for urban wind technologies - Off-grid properties, high-wind speed locations, rural farms, non-utility and aesthetic purposes, backyard engineering or DIY 09:54 Outro 10:11 Thanks to Brilliant for sponsoring this video! In this video I'll take you through the science and engineering reasons why rooftop solar is much easier than small wind, and show that the same wind turbine on a roof is likely to generate less than 10% of the energy a turbine of the same size would generate in a nearby wind farm. And, because I know most of you found this video because you already know you want to do a DIY wind energy project (they're fun!) or have an off-grid project that needs wind energy to diversify your energy, I have included some resources (Hugh Piggott's great books on DIY wind energy and certified small wind turbines if you want to buy one).
