Environmental technologyhu:Perma/TECH Focus: Equipment, energy systems, and appropriate technology. Description: This knowledge domain focuses on the development and use of tools, technologies, and energy systems that are sustainable, accessible, and adaptable to local contexts. This includes renewable energy solutions (solar, wind, biogas), low-tech innovations, and open-source designs that empower communities to meet their needs without reliance on centralized or environmentally harmful systems. The emphasis is on simplicity, durability, and the ability to repair and repurpose tools, fostering self-reliance and resilience. Here, in Open Book of Permaculture you can share your knowledge - proven ideas and practical insights to help develop a manual on this topic. Energy Supply Solar Panel System Photovoltaic panels that convert sunlight into electrical energy. Green Computing Study and practice of using computing resources efficiently.. Wind Turbine Generator A device that converts wind energy into electrical energy. Micro Hydro Power Plant A system that harnesses energy from smaller watercourses. Biogas Reactor A device that produces gas from organic waste for energy generation. Solar Collector System A device that converts sunlight into thermal energy, typically used for hot water preparation and heating assistance. Heat Pump Extracts environmental thermal energy (from air, soil, or water) and transfers it at a higher temperature into the building for heating or cooling using a compression principle. Biomass Boiler Generates thermal energy by burning solid organic materials (e.g., wood, pellets, briquettes) for heating and domestic hot water. Heat Recovery Ventilator Utilizes the heat from outgoing stale air to preheat incoming fresh air, minimizing heat loss from ventilation. Water Movement Systems Drip Irrigation System An efficient irrigation technique that slowly delivers water. Rainwater Harvesting System A system for collecting and storing rainwater. Organizations Open Source Ecology An open source, libre economy is an efficient economy which increases innovation by open collaboration.
