This piece makes use of data from the World Bank to give a performative snapshot of the energy use of the world’s most populous countries. Each performer’s tempo and total duration reflects the energy use per capita and the total population of one country. For each realization, the performers select the year(s) and countries to represent, choosing from 1993-2008 and the ten most populous countries.
