Off-Grid Country Lighting Assessment Methodology

The off-grid lighting market model estimates the fuel-based off-grid lighting energy consumption and savings potential derived from replacing kerosene lanterns, candles and torches (flashlights) with solar LED lanterns, based on a one-for-one replacement. The model incorporates electrification rates, GDP, population, fuel prices and other inputs.  The model also assigns off-grid technology mixes on a per-capita basis based on a sample of country studies. The CO2 savings are calculated based on the combustion data for kerosene and candles, and a life-cycle assessment of dry-cell batteries (for torches).  More detailed information for the off-grid Country Lighting Assessments can be found here.
