Five trends in creating energy-efficient cities

Increased urbanization and growth of the middle class, particularly in China and India, will help drive global energy demand higher even with significant efficiency gains, as outlined in the ExxonMobil 2017 Outlook for Energy. The push for greater energy efficiency is already well underway with city governments implementing innovative sustainable solutions that are transforming city life.
