The first portion of the presentation establish models to evaluate parameters effectiveness to the energy system. It’s a useful tool to do trade studies to determine the priorities of system design optimization. Similar approach could be tailored to different systems or parameters. This approach provides a means to take the system holistically instead of individual components.

The HOMER presentation presented similar approach for different power system architecture in rural area.

AKM Azad presented solar home system component qualification testing procedure. This is the first presentation that works with qualifying actual of the shield product. To provide a comparison, figure of metric is also established.

Nathan presented a study for the new cookstove adoption to the rural area. The figure of merit not only takes the cookfuel efficiency, which includes time to prepare biomass, but also the adaption rate for the cookstove. It shows that a great product may have great performance but lacks of the adaption greatly reduces the value of the product. Also, there is no solution fits all because the “customer” need simply varies from cooking 5lbs to 100lbs food. Differentiation for different needs are needed.

Yaser, the last presenter, adds an new element to the figure of merit on the global level- Peace, to address the conflict of energy resources. It’s an new thought to integrate the energy solution to a larger global scale.

Tutorial 1A. Village energy systems: Understanding the problem and comparing rural energy options
Speaker: Nathan Johnson, HOMER Energy

How should we help solve rural energy poverty?
“… the user knows more about their life and environment than you do, keep an open mind”
“Focus on need not the absence of a particular technology”
“Try considering the user as a consumer”
“Poverty alleviation has many paths”

Tutorial 1A. Village energy systems: Understanding the problem and comparing rural energy options
Speaker: Nathan Johnson, HOMER Energy

Speaking from his experience in Uganda, Mali, Vietnam, China, and other rural areas, Nathan is telling us what typical leads to failures of engineering projects (infrastructure, durable goods – pumps, stoves, consumable goods) in rural areas. Some have poor problem definitions to start with, others rely on good linkages between Technology, Policies, Funding, Management to succeed. I must agree, solving the technological challenges is just one part of a bigger puzzle.
