Rising global energy use remains a major challenge, with cities and regions being central players in making energy more secure, clean and sustainable. To transform from a linear to a circular economy there is a growing need to take advantage of renewable resources, including energy. ICLEI supports the cities and regions initiatives aiming at 100% Renewable Energy. Since 2007, ICLEI has offered an international forum for discussion and exchange among policymakers and practitioners from various levels of government, energy experts, energy services providers, researchers and business representatives.
