Telling stories of watts and of people through pictures: photography enters the challenge of universal access to modern and sustainable forms of energy, which in 2015 became one of the United Nations Sustainable Development Goals. This is Energy Portraits. With his camera Marco Garofalo enters the homes of a hundred families across four continents — Africa, South America, Europe and Asia — to recount, in one and the same format, what access to energy means in daily life: the same framing, the same light, and every time a different household.
