PureSelfMade, a company based in Germany, is developing a how-to book with designs for small wind turbines ranging from 600W to 3kW. Michel from Sweden attended a course to learn how to build a turbine for his home, highlighting the growing interest in renewable energy solutions. The company sells pre-manufactured parts made from transparent and locally sourced materials like wood, making assembly easy. Wind turbines can complement solar panels, especially in areas with limited sunlight, but the challenge remains in making them affordable. PureSelfMade offers models at a lower cost compared to traditional options, aiming to make small wind turbines more accessible for homeowners looking to reduce their carbon footprint.
