“…As a matter of fact, the so‐called do‐it‐yourself philosophies are connected to frugal innovation (Reardon ; Banerjee ). Wind turbine blades, for example, can be made out of local wood material, if glass fiber is not available (Latoufis et al ). Locally manufactured technologies, such as wind turbines, could actually have a considerable potential for the local economies in low‐income countries (Leary et al ) linked to local employment and education.…”

Frugal innovations have recently emerged to feature low‐cost technologies and business innovations to serve consumers in emerging markets and improve their quality of life. Although the concept of frugality is well known, the present literature on frugal energy innovations, or energy frugality, is scarce, which could lead to overlooking its true characteristics. Therefore, we propose a framework for defining energy frugality based on a detailed analysis of several low‐cost sustainable energy technologies. The five‐criteria assessment method developed will help to identify potential frugal energy innovations and will increase the adoption of these technologies through better matching to local needs. Fuel‐efficient biomass cooking stoves, small‐scale photovoltaic systems, and pico‐grids are examples of such frugal energy technologies.

During the last decade, the local manufacturing of small wind turbines has become a common approach in rural electrification applications, especially among international networks of renewable energy practitioners. Locally manufactured small wind turbines (LMSWTs) used in off-grid battery based renewable energy systems, typically utilize coreless axial flux permanent magnet generators (AFPMGs) due to their simple manufacturing. Typically, low cost three phase uncontrolled diode bridge rectifiers are used for the direct coupling of the AFPMG to the battery bank, which increases significantly the total harmonic distortion (THD) content in the stator current. LMSWT users have occasionally reported AFPMG noise as contributing to the overall acoustic noise emissions of the small wind turbine, especially during low wind speeds. In this paper the relation between current harmonics and acoustic noise emissions in AFPMGs is investigated and verified experimentally, while appropriate passive filtering techniques are utilized in order to reduce their effect. Furthermore, the overall acoustic noise emissions of a LMSWT are measured experimentally in the field and are compared to noise standards for residential areas. Finally, electromagnetic and aerodynamic sources of acoustic noise are investigated experimentally in the field, while design recommendations are developed for LMSWTs towards the reduction of acoustic noise emissions.
