The value of user-centered design is indisputable. If we want to design products and services that work for the end-users, we have to take their feedback onboard and design with their active participation. That's how to ensure that we meet their needs the solutions are highly relevant and usable. Same applies to the design of energy technologies, whether it’s solar home systems (SHSs), pico-solar lanterns, or energy systems connected to mini-grids. However, the question I had to ask myself when conducting research on the users of SHSs in Rwanda was: Are we really including all users in this critical process?
The realization that we might accidentally be excluding some users while designing energy access solutions
came in April 2016. I was sampling participants for a study related to my PhD research at University College London, collaborating with BBOXX, one of the providers of SHSs in East Africa and elsewhere. I saw how many of the registered owners of SHSs in Rwanda were male and female: 94 percent vs. 6 percent, respectively. If we were to only go with random sampling, we would end up with hardly any women while getting customer feedback by conducting interviews, regular satisfaction surveys or focus groups. The numbers would be heavily skewed towards men, by default.
This is particularly important for providers of products and services in communities where men tend to be the heads of households and men are in charge of managing household resources (purchases, expenditures etc.). In those populations, men are the ones who are likely to answer the phone when a provider calls to get feedback. And yet, as I quickly learned in focus groups that I held before conducting household surveys in my research, despite not being the owners of the systems, women are their primary users, along with children.
They are the ones who stay at home during the day and use the services that are made available, i.e. lighting, mobile phone charging, access to information via radios or TVs, more than their male counterparts. Children also spend more time at home and benefit from having access to electricity in considerable ways by having a cleaner, improved study and play environment, and no longer having to wander off at night to seek a bright place where they can meet friends or do their homework.
For the in-household part of surveys I conducted, I decided to go for purposive sampling, a method of selectively choosing participants based on the population and objectives of the study. I chose the method in order to reach more women than I would have reached through random sampling. That’s exactly what happened: among 97 in-household surveys (where purposive sampling was applied) 45 percent were female vs. 55 percent male, whereas among the 168 telephone survey participants (where random sampling was applied) only 16 percent were female vs. 84 percent male (still a higher overall proportion of women than in the total population, as demonstrated above). I found that it was much easier to reach women for in-household surveys precisely because they are the ones more likely to be at home during the day, as opposed to men who work outside of their homes and are only there in the evenings.
Collectively, among all survey participants (265), when asked about who in the household uses the SHS the most, 61 percent of men said it was their spouses and 66 percent of women said it was themselves. Focus groups and participatory photography workshops (which doubled as data-collection tools) confirmed that split. As a result, the impact on the women
has been found to be more significant than on men. Being responsible for household chores, women can now extend their work hours into the evening and no longer have to wake up early to make sure they complete their tasks before the sun goes down. Now they can easily perform them in the evening, having a much brighter, safer and cleaner source of light than the candles or kerosene lanterns they used to rely on prior to purchasing a SHS. The improved well-being also comes with the ability to cook in a brighter place, without having to worry about tripping over kitchen appliances, or the need to hold a lamp, a candle or a torch while preparing meals.
As one male participant reported: “It's my wife who pushed me to buy the system. There is [a] big challenge that she used to face. Whenever we could afford a torch, my wife would do some activities holding that torch in her mouth, for example to cook, and she used to tell me that she was feeling pain and we were always wondering how we would explain to the doctors about her illness. I would also wonder how this was going to end. But now she no longer holds a torch in her mouth and she also tells me that she no longer feels pain. She can also testify herself, it is not a joke.” (Male, Nyamata, Rwanda).
Men often talked about women when asked about impact of having access to electricity in their homes. Another one compared what was challenging for his wife before and how her daily activities have been made easier since system adoption: “My wife is also able to cook, help kids to take shower in the evening. Before, it used to be very difficult because the lantern brightness could not reach all the places of the house. But with the system she can do all the activities from whichever side she wants. She can also wash dishes in the evening all this because of the brightness of the lights.” (Male, Musanze, Rwanda)
Nursing her baby at night with much more ease, with a bright light available at a push of a switch, was one of the key changes for the better for a female participant in Musanze: “I do all my activities in a bright place and now that I gave birth; the place is bright. The fact that the place is bright it is enough for me.” (Female, Musanze, Rwanda)
It is clear that in order to engineer solutions
to satisfy the needs of those without access to basic services we need end-user feedback. The iterative process of user-centric design, from planning, researching, designing, adapting and measuring (on repeat), can only bring true value if all end-users are involved. That includes the obvious ones and the ‘hidden’ ones, who can often be the ones using and benefiting from energy technologies the most.
This feedback is pivotal as the daily experience of using a technology translates into a lot of learning about how to improve it. However, the voices of those who are yet to gain access, be it to SHSs or other technologies offering energy access, should also be integral to the process, and should include both men and women, as different needs and aspirations might exist among them.
In many other Sub-Saharan African countries, where over 500 million people are currently without electricity, the gendered roles are similar to those in Rwanda. Missing out on including women’s voices can result in poorly engineered solutions, or, at best, solutions engineered for some, not all. If the problem persists, the United Nations' Sustainable Development Goal 7 (SDG7), 'Ensuring access to affordable, reliable and modern energy for all,' can never truly be achieved.
