COUNTRY DATA: Overview

Country Data: Overview > Country Reports > Methodology

This area of the LuminaNET site contains a series of 80 draft Country Lighting Assessments based on a modeling effort that quantifies the magnitude of fuel-based off-grid lighting around the world.  Prepared by the UNEP/GEF en.lighten initiative in close collaboration with the Lumina Project at Lawrence Berkeley National Lab, these country reports offer estimates of off-grid lighting energy consumption, CO2 emissions, and the savings potential for switching from fuel-based lighting to solar LED systems. Taken together, these 80 countries represent 1.3 billion people living in 285 million off-grid households around the world.  

We are inviting LuminaNET members to review the initial reports, and provide feedback under each relevant country profile including corrections, updated data, and impressions about the draft results.

In particular we would appreciate country-specific data on:

  • the types of off-grid light sources
  • the number of lights per household or business
  • the hours of use per household or business
  • the prices of fuel/candles/batteries
  • the fraction of lighting fuels that have been saved in practice by switch to Solar+LED or other alternatives

When posting your comments or suggestions, if you have any supporting material (e.g., reports, spreadsheets, links, etc.) please include it with your comment.

New assessments will then be published for the countries, taking this input into account. 

Reviewers may be aware that there is very limited detailed market data for off-grid lamps/luminaires used by households, as well as a great deal of uncertainty around the operating hours, end-use prices and other critical inputs to the market model. A separate page summarizes the methodology and assumptions followed, and any comments and suggestions on the approach can be posted there. A good deal of key information has already been gathered which will be incorporated into the next update of the reports.

We thank you very much for your time and assistance with this effort. With your input, we will be able to improve the estimates and publish a revised set of country reports over the coming months.  We look forward to your feedback.

This work was prepared by the UNEP/GEF en.lighten initiative, with support from Evan Mills from the Lumina Project. The work also benefited from the expert input from the Global Off-Grid Lighting Association (GOGLA), Lighting AfricaOSRAM, and Philips Lighting. We thank these organisations for their contributions to the analysis.

Note that manufacturers' FOB price is not the destination market's off-the-shelf price.

The price of the average usable solar lantern in Nigeria is not $18. Solar lanterns in this price range are basically the least priced and often of little of desired or required value. At the beginning of somewhat usable or useful solar lanterns are products priced above $40. Average usable and practical solar lanterns are priced beyond $80. This $18 figure significantly impairs the worth of off-grid lighting market in Nigeria at the going rate.

Dear UNEP team,

As per Evan's comment on my mapping blog, would you be interested to have these pdf documents' data put into a tabular format online, so people can search through the data online, and so we can map the data across all countries on our mapping platform, to allow easier cross-country comparisons in visual and tabular formats?

If this was of interest, we would require access to the pdf documents in editable form, preferable Excel or database format, or at minimum, .doc format so we can build up a database.

Am really excited to see some systematic, large-scale market analysis reports now available, rather than ad-hoc and fairly random efforts that we've seen in the past, so that we can truly take steps towards Energy for All.

Thanks to Evan for making me aware of this post and its potential for mapping, as well. I also note that the en.lighten UNEP team is based in Paris, which I'll be visitng on July 11th, so perhaps we can meet in person.

Warm regards,
Stewart

Joshua - that's great to hear.  We hope more LuminaNET members contribute and add value to this for everyone's benefit.

Evan,

We are getting a ton of mileage from this! Thanks a million.
