In many more environments, smart meters can coordinate the energy consumption of appliances to smooth out variations in overall energy consumption and achieve more effective use of variable renewable energy sources. Impactful loT interventions in development either improve efficiency (achieving similar levels of impact with fewer resources) or effectiveness (increasing impact with similar levels of resources).6 loT applications could help promote monitoring and evaluation, and achievement of nearly all the existing Millennium Development Goals (MDGs) and post-2015 Sustainable Development Goals (SDGs) (Table 3, pages 39-40). For example, sensors in agricultural fields are monitoring soil conditions and moisture levels.
