Right. And the way to balance environmental concerns with the objective of lower rates is to calculate the least-cost generation portfolio, including environmental costs to Hawaii residents. By that standard, natural gas comes out lean, clean, and green. 
Btw, Chairman Iwase is disingenuous when he refers to the 100% clean energy goal. He knows perfectly well that the requirement is for total renewable (including rooftop solar) divided by NET utility sales to be at least 100%. That can be satisfied with a portfolio that includes 50% of total generation coming from coal, oil, and natural gas.)
