Problem Statement
• Analyze alternative energy solutions– No utility– Utility as backup– Alternative energy sources as backup
• Economic analysis• Load analysis
Solution Approach
• Research alternative energy sources– Solar, wind, fuel cells, biomass, micro hydro,
and micro turbines• Research geographical area, area
regulations, and interconnection with utility• Create website to post the solutions
Operating Environment
• Data is organized and presented on a website that can be viewed using Windows XP and Internet Explorer
Intended User
• Farmer or rural resident
• Supplement or eliminate electric utility
Intended Use
• Provide information for a rural resident interested in alternative energy
Assumptions
• The user must have basic computer skills• The user must have knowledge of power
needs• The user must have knowledge of system
requirements• Six sources where considered
– Wind, solar, fuel cells, micro hydro, micro turbines, and biomass
Limitations
• Exact cost of each alternative source • Installation cost• Maintenance cost• Fuel Cost
End Product and Other Deliverables
• Website• Informative spreadsheets with the final
results• Final Report
Present Accomplishments

Approaches Considered
• Interactive program with user inputs which gives recommendation output
• Informational website (the approach used)
Project Activities
• Research• Design• Implementation• Testing
Research
• Sources– Economic analysis– Viability for user– Energy storage
• Sources divided into two categories– Those which require no fuel– Those which require fuel
Wind Power
• Advantages– Low cost– Many turbine sizes available– No fuel required
• Disadvantages– Unreliable as primary source– Requires tower construction
Solar
• Advantages– Small size– No fuel– Good for low power applications
• Disadvantages– Expensive– Unreliable as primary source
Micro Hydro
• Advantages– Requires no fuel– Low maintenance
• Disadvantages– Unreliable as primary source– Many government regulations– Not environmentally friendly
Micro Turbines
• Advantages– Small size– Affordable for large power needs (>30 kW)– Can use multiple fuels
• Disadvantages– Expensive for small power needs– Fluctuation of fuel cost
Biomass
• Advantages– Can often be substituted as diesel fuel– Generator is low cost– Can meet many different power needs
• Disadvantages– Fluctuation of fuel costs– Noise– Takes up a lot of space
Fuel Cells
• Advantages– Useful for energy storage– No combustion required
• Disadvantages– Expensive– Requires fuel source to generate hydrogen– Involves many different components
No Utility Case
• Main source would most likely be wind• Backup source would be Diesel/biomass
generator or micro turbines
Inverter &Controller
Main Source AC Load 120 VAC
12, 24, or 48 VDC
Generator Controller
Secondary Source
Batteries 120 VAC
12, 24, or 48 VDC
Utility as Backup Case
• Main source is most likely wind• Requires safety equipment to interconnect
with utility company
Inverter &Controller
Main Source AC Load 120 VAC
12, 24, or 48 VDC
Electric Utility 120 VAC
Utility as Primary Source
• Diesel generator is most cost effective• Micro turbines and batteries also a
possibility• User would have to manually switch over
in the event of power loss
Informative Website
• Provide information about each source• Explain how to calculate monthly energy
usage (kWh)• Present spreadsheets with cost analysis• Provide links for additional information
Data Organized into Spreadsheets
Sample Webpage
Testing
• Design was tested by making comparison with systems currently in use
• Wind was most cost effective alternative source
• Diesel generator was most common form of backup
Other Activities
• Team attended an 8 hour long alternative energy workshop at the University of Minnesota
• Focused on many types of alternative energy (solar, wind, fuel cells)

Schedule
Project Evaluation
• All required deliverables were completed• All tasks completed on schedule• Project was a success
Commercialization
• No plans to commercialize this product• Not likely to be high enough demand• Possibility exists to sell advertising space
on website if popular enough
Recommendations for Additional Work
• Installation and maintenance costs• Reevaluate project within a few years due
to rapidly developing technology• Obtain funding to implement a system
Lessons Learned
• What went well– Research was effectively divided among
group members– Flexibility of scheduling meetings
• What did not go well– Lack of understanding of project definition
Technical Knowledge Gained
• User energy needs• Cost of equipment• Components required to create system• Web design
Non-technical Knowledge Gained
• Communications skills• Time management• Risk management
Risk Management
• Anticipated risks– Loss of team member– Difficulty finding sufficient data to complete
research– Unsuccessful approach
• Management of risks– Share information between group members– Frequently evaluate project approach
Risk Management
• Unanticipated risks– Lack of understanding of project definition– Loss of faculty advisor
• Management of risks– Extra effort at later stages of project to make
up for previous lost time– Additional effort on the part of remaining
faculty advisor
Closing Summary
• Informational website created• Present information in spreadsheet form• Power output and cost evaluation of each
source• Links for additional information
