Home Power Feb Mar 2011 lists the importance of Native American properties as a place for alternative energy production:
"The energy potential of Native American lands is large. There are 565 federally recognized tribes in the United States. These tribes own and manage more than 95 million acres of land across the nation--11 million more than the National Park Service and almos 5% of the total area of the United States.
According to the US Dept of Energy's Tribal Energy Program, those lands hold an estimated 10% fo teh country's resources, including the potential for 535 billion kilowatt-hours of electricity per year from wind power. Solar has even greater promise, at 17 trillion kwh per year---the equivalent of 4.5 times the total national energy generation in 2004."
