In the middle of the desert, near the Grand Canyon, workers are bringing electricity to Christine Shorty's home. Thanks to them, this Native American woman from the Navajo Nation will finally have electricity, a luxury still out of reach for more than 10,000 families in the region. "It's climate change. It's getting hotter," sighs the 70-year-old retiree. "It would be easier for us with a fan, and maybe air conditioning." While most of the United States was electrified in the 1930s, in the Navajo Nation, which spans across Arizona, New Mexico, and Utah, efforts didn't really begin until the 1960s, and the power lines are still insufficient. "We're still trying to catch up with the rest of America," explains Deenise Becenti, from the Navajo Tribal Utility Authority (NTUA), the agency responsible for managing infrastructure on the reservation. "That surprises many people. They ask, 'Why do third-world conditions still exist here in the United States?'" IMAGES AND SOUNDBITES ARRANGED IN SEQUENCES
