Let's leave aside the internal contradiction implied by "cheap" and "clean" coal power plants.  There is not a single lump of coal to be mined anywhere in Hawaii.  Dependence on a non-renewable resource that must be 100% shipped in, and for which Hawaii will face increasing price competition both domestically and internationally, is a horrible step backward. 

It's also not 𝙥𝙤𝙣𝙤  to impose environmental degradation elsewhere to provide more power here at the expense of people elsewhere -- something that will inevitably happen, since the current federal administration is already commanding sane environmental policies to be jettisoned.  Hawaiian culture demands that we take great care to 𝙢𝙖𝙡𝙖𝙢𝙖 𝙠𝙖 𝙝𝙤𝙣𝙪𝙖. 

Our only rational course is to pursue local energy self-sufficiency using environmentally sound, locally renewable resources such as solar, wind and ocean energy.  We can do that, and save the hoary bats too -- because that's what 𝙧𝙚𝙖𝙡 adults do.
