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.

Do Nothing

• Imagine living without electricity in the 21st
  century.
• No lights
• No internet
• No appliances
• Current means of electricity generation are
  expensive and alternatives are efficient or safe.

Put in Power Lines

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.

Build a Wind Farm

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

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).

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

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.

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.

Ranking Alternatives

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