The future of energy is crucial for human mobility and well-being on a finite planet. What energy types are available to cover global needs? To what extent can they be produced and consumed safely? How can the negative effects of global warming, climate change, and environmental degradation be avoided? Who will benefit, and who will be at risk? Faced with such urgent questions, it was timely that the World Expo 2017 was dedicated to the theme of “Future Energy.” Held from June to September in Kazakhstan’s capital, Astana, a total of 115 countries, 22 international organizations, and several transnational corporations set up their own pavilions and exhibition spaces. Close to four million people visited the three-month-long expo, including an estimated five hundred thousand from abroad.
