Blake, I'm more than happy to discuss these issues.  First of all, you're right, we would certainly prefer if HART or the City were developing dedicated renewable electricity production to power the rail system. But ultimately, as you may be aware, we fought for many years to get the 100% RPS standard by 2045 passed two years ago.  No matter where the rail system gets it power, whether purchased from HECO, or HART owned power generating facilities; we are 100% confident it will be 100% renewable by 2045 at the latest.
Secondly, the City and County of Honolulu has no way to significantly add public transit capacity without building the rail system. TheBus has been at-capacity since the early 1980's due to the phenomenon called "bus bunching".  It's too technical to explain in detail here, but to summarize Honolulu's narrow geography squeezes too many buses onto too few major east-west roadways and the buses are getting backed up behind each other. Buses average 4-8mph in urban Honolulu.
