Kaua’i Island Utility Cooperative
Renewable Energy Technology Assessments 1.0 Executive Summary
• Socioeconomic impact (7.5 percent)
• Incentives/Barriers (5 percent)
Cost of energy accounts for 50 percent of the overall screening score, with the rest
of the criteria contributing varying degrees to the remaining 50 percent. As some of the
scores will change over time as a technology matures or KIUC’s needs change, screening
of technologies was done at intervals of 3, 5, 10 and 20 years in the future. Highlights of
the screening include the cost of energy (Figure 1-1) and Kauai resource potential (Figure
1-2).
