||Rosa lives in Kakuma, a border town located in North-Western Kenya. Her husband left her to raise their three children alone. She sells food at the market but loses one full day per week trekking to the surrounding hills to collect firewood. Rosa's low earnings mean that she cannot afford to buy firewood or kerosene: "For me getting energy for cooking and lighting is a daily worry. It's so hard to find firewood that I cook for my family only once a day in the evening. The fire provides the light for cooking and eating a meal with my children. After eating is bedtime." The lack of lighting means that the children cannot do their homework or get help from their mother after dark.
