In the Navajo Nation, electricity may be a fragile commodity as climate change intensifies. Other tribes in the United States face similar energy quandaries. The United States Department of Energy (DOE) announced on Sept. 2 that it is requesting applications to co-fund renewable energy, energy efficiency, and combined heat and power to help increase the climate resilience of indigenous communities. The available funding is estimated to total around $4-6 million. Applications are due by Dec. 10.
