4.4.2 Kauai Resource Potential
The developable potential was estimated for each renewable technology for the
next 3, 5, 10 and 20 years. The background to these estimates is documented for each
technology in the previous section under the “Kauai Outlook” subsections. The annual
electricity generation (GWh/yr) estimates are shown in Figure 4-3.
