Little Sun is an organisation established by artist Olafur Eliasson and engineer Frederik Ottesen to spread clean, affordable energy across the world. Since 2012, Little Sun has distributed over 1.2 million personal solar devices worldwide to students, refugees, teachers, and community health workers in areas without electricity. Through these efforts, Little Sun has generated 58 million additional study hours for children, reduced 800,000 metric tons of CO2 emissions and stimulated $150 million in household-level savings by substituting kerosene with clean energy.
