Viable Productive Uses of Electricity Programs Remain Elusive:
A practitioner's field-based recommendations for overcoming challenges
By Brian Gurr and Allison Archambault
Productive uses of electricity such as machines that can perform agricultural processing are core to unlocking the economic development potential of community microgrids around the world. While energy access funders are now interested in this concept, the reality remains that truly transformative ‘plug and play’ applications remain elusive. Read the full paper here.
Medium Voltage Distribution Considerations in Clean Energy Community-Scale Microgrids
Community-scale clean energy microgrids have characteristics that make them different from large-scale infrastructure and even from diesel-powered microgrids. While there is little written on this topic, we posit here that choosing an appropriate medium voltage level is important for stable and efficient microgrid operation.

For Cook and Climate: Certify cookstoves in their contexts of use
By Samer Abdelnour and Crispin Pemberton-Pigott in Energy Research & Social Science, Vol. 44, 2018, pg. 196-198
"Improved cookstoves are widely promoted as health and climate improving technology, yet there remains a wide gap between their reputed benefits and the inconclusive outcomes of most interventions. An increasing number of scientists suggest that the popular lab protocols used to test, rate and model the benefits of improved cookstoves are at least partly to blame.
Insights from a recent study of improved cookstove users in Darfur, Sudan, reveal the extent to which the logic and goals of lab-based testing protocols differ from actual cooking practices. We elaborate on the climate and energy policy implications of decontextualized lab tests and conclude with a call to design, test and select for dissemination only those improved cookstoves that are rated on the basis of their intended contexts of use."
