1. Bringing Power to the People A solution for bringing electricity to remote locations.

3. 10,000 Homes without electricity. Current means for alternatives –Refrigeration Ice box –Nearest ice supply 30 miles away. –Gasoline Generators for Electricity Expensive ( $0.75/kilowatt-hour), Noisy, Emissions, Relatively low efficiency. –Heating Firewood, Kerosene Heaters –Kerosene is not a clean burning fuel, and can be a fire hazard. –Lighting Kerosene lamps, Candles, Fire –Not bright enough, toxic emissions, fire hazards.

5. Do Nothing Imagine living without electricity in the 21 st century. –No lights –No internet –No appliances –Current means of electricity generation are expensive and alternatives are efficient or safe.

6. Put in Power Lines

7. Cost of Power Lines It costs $500,000-$3,000,000/mile to bury cable, depending on soil conditions and other factors. It costs $120,000/mile to install overhead power lines. Some houses on the reservation are not near any other houses. The cost of running power lines to one house or even a group of houses that are isolated by miles of open space gets expensive very quickly. Overhead power lines are not visually appealing and buried power lines lead to soil disruption and erosion.

8. Build a Wind Farm

9. Wind in NM at 50 meters

10. Build a Power Plant Very Expensive Does not eliminate the cost of a grid Fossil Fuel –Emissions –Reliance on fossil fuels

11. Sacred Power Inc. A Native-American owned company based out of Albuquerque. Works with the Navajo Nation, US Dept. of Agriculture, and US Dept. of Interior to bring power to remote locations in the Navajo Reservation. In 2002, Sacred Power Inc, got a $607,000 contract with the Dept. of Interior for 16 mobile hybrid power systems ($37,937.50/unit).

12. SP 1200 Stand-alone PV-Hybrid System 14 feet long, 10 feet high Constructed on wheels or skids. Built in solar tracking array for maximum efficiency. Solar collection batteries for energy storage. Back-up, high grade propane generator w/ 1 month supply tank. Maintenance free components. Capable of providing a continuous output of 2.5 kilowatts/hour under normal conditions for the area. –2.5 kW/h x 1h x 24 hours/day x 30 days/month –1800 kWh/month. Cost of operation is about $0.50/kWh. Some emissions from burning propane (much cleaner than gasoline).

15. Renewable Success 2001, Sacred Power Inc. got a $431,000 contract to design and build a solar power system that can be used for teaching. 2002, Sacred Power Inc. got a $588,000 contract for 12 solar telecommunications shelters for remote locations. –4 employees –Subcontract some work –Built a new 7500 square foot manufacturing facility

18. Renewable Success Cont. 2005, Sacred Power Inc, was awarded an $825,000 grant to build and deliver 50 new solar/wind hybrid units to remote homes on the Navajo Reservation. ($16,500/unit) –No propane required –Enough electricity to power a highly efficient refrigerator and lighting system (supplied by Sacred Power), and a small appliance. –Operational cost is $0.

20. Cheaper from 2002 to 2005 From $37,937.50 /unit for the propane/solar hybrid To $16,500.00 /unit for the wind/solar hybrid system Wind turbine much cheaper than the high grade propane generator, but has lower power output. Production is much cheaper since in 2002, Sacred Power opened its own manufacturing facility.

21. Ranking Alternatives 1.Hybrid Renewable Energy Systems Cheap, clean, no grid access needed, sustainable. 2.Power lines Added stress on existing power generation facilities (drives cost up). 3.Power generation Renewable energy source (biomass, wind, solar) Fossil Fuel power plant. 4.Do nothing
