Energy Data Analytics Lab: Electricity Access in Developing Countries from Aerial Imagery (2017-2018)
Access to reliable electricity is strongly correlated with economic prosperity and health. Over 15% of humanity has no access to it at all, and far more have access only to intermittent supplies that preclude most productive energy uses.
Research on sustainable energy transitions being conducted at Duke and elsewhere is trying to better understand the drivers and impacts of electrification on health, land use, the environment and the local economy. However, current methods for assessing access rely almost completely on household surveys or highly aggregated (e.g., national-level) data sources.
This project designed innovative techniques to evaluate electricity access in developing countries through machine learning applied to aerial imagery data. The team filled critical gaps in energy access data collection and evaluation by piloting and then applying automated algorithms for generating spatially-disaggregated data on electricity access in developing countries using aerial imagery. The team also developed new machine learning techniques to extract information on energy infrastructure and consumption using high-resolution aerial imagery.
In 2017-2018, the team focused on producing high resolution estimates of electrification rates in the Indian states of Bihar and Uttar Pradesh. The team curated a dataset of electricity access survey data and satellite imagery for all villages in Bihar and extracted features from satellite bands to be input into an automated classifier. The team trained a gradient-boosted decision tree classifier using extracted features such as light at night, population density, and possible agricultural activity, to predict whether 16,389 individual villages in Bihar were either electrified or un-electrified based on ground truth data from the Indian government’s GARV dataset.
The team then then used this algorithm to predict electrification of villages in the neighboring state of Uttar Pradesh.
