Renewable Project Status Board
We are committed to increasing Hawaii's use of clean energy and reducing our dependency on imported oil. This status board tracks the progress of new and upcoming renewable energy projects and the impact that they will have in increasing our overall RPS % points – essentially, the percentage of renewable energy on the grid – to meet our clean energy goals.
