The Pinoleville Pomo Nation (PPN) is a federally recognized, self-governing Native American tribe located in Northern California's Mendocino County on the outskirts of the city of Ukiah; it is dedicated to ensuring that its 'members enjoy safe, healthy, and environmentally benign environments, both natural and built'. This report aims to present and analyze information on the potential of renewable energy power systems and electric vehicle charging near the PPN to provide an environmentally-friendly, cost-effective energy and transportation options for development. For each renewable energy option we examine, solar, wind, microhydro, and biogas in this case, we compiled technology and cost information for construction, estimates of energy capacity, and data on electricity exports rates. During the one year anemometer testing, it was determined that wind speeds were higher than expected (several over 20 MPH), but that the average wind speeds were between 4-8 mph which makes a wind farm or wind utility unfeasible for the PPN. For a biogas utility, it was determined that it had the lowest levelized cost of energy (LCOE) ($133.43/M Wh) of the energy sources tested and that there were several sources of organic feedstock for an anaerobic digester; however, it was unknown how much feedstock these sites produce or if PPN would have reliable access to the feedstock. For micro hydro, the head from Ackerman Creek at one of its largest velocities was 0.453 feet (0.138 meters); however, CARES determined that approximately 4 m of head is need for microhydro system to be viable. For a solar electric vehicle charging system, it was determined that the land area required for peak traffic locations becomes restrictive and thus makes a purely off grid solar EV charging system untenable. Finally, it was determined that a 1-3 MW solar utility was the most viable option for the PPN due to its LCOE of $233.07/MWh and its abundant feedstock that is more easily accessible.
