Power to the People – Bringing clean energy & water to rural Navajo elders

By John Connell

Navajo people living in the Four Corners Region of Arizona, New Mexico, and Utah have some of the most abundant sunlight

in North America. In fact, they are the major electric supplier for the entire southwest through coal mining and coal-ired

plants. Perhaps surprisingly, however, over 20,000 Navajo still live in homes without electricity, running water, or sanitation.

Among the hardest hit are elders with disabilities and health problems. Most have to A solar system torture test
