While making buildings more energy-efficient is the cheapest way to reduce emissions, the energy efficiency improvement rate is actually slowing down. Eskişehir, a Turkish city of 870,000, is showing cities around the world how they can lead on building efficiency.

Millions of Indians still lack power, despite significant increases in electrification in recent years. Rooftop solar is a promising solution for the country's many rural health centers.
