a rural off-grid electricity program in Burundi lead by UNICEF with a randomized assignment of village level power stations (two pictures above) from 2014 to 2017.  I added an in-house air pollution measurement component to this exercise, using a device developed by the Berkeley Air Monitoring Group (http://berkeleyair.com/).
