1.5 billion people lack proper access to electricity. Many buy kerosene, which can cost 30 percent of their income. It sends millions of metric tons of carbon dioxide into the atmosphere every year.

The only way we really create change is to enter any situation with the humility to listen and to recognize the world as it is, and then the audacity to dream what it could be, to have the patience to start and let the work teach you, to be willing to lead when you need to lead, and to listen. To have a sense of generosity and empathy, but not over-empathy, because accountability is so critical to building solutions that work.
