About Hawaii?That milestone broke new ground in the clean energy transition because no other state had attempted to eliminate coal without building new fossil gas plants. Hawaii sought to show that renewables and batteries are ready to take over from the most carbon-emitting power plant fuel.

But the undertaking has demonstrated how small-scale clean energy can solve problems when big clean energy projects fall behind.
