Ask the Japanese how they have been generating electricity since shutting down their nuke plants after the Fukushima incident.  They are generating power with coal and lot's of it.  Why, because it's cheap and reliable. If you've ever been to Tokyo or any big Japanese city it becomes quite apparent they require massive amounts of electricity to light their cities and cool their homes and offices.  Wind and solar are woefully inadequate for that scale of power generation.  Also, heavy manufacturing for which the Japanese are well known also relies on large amounts of reliable and inexpensive power.  Call me crazy but I can't see wind and solar power filling that niche anytime soon.  The insane 100% renewable goal will be disastrous for Hawaii driving up already obscenely high electric rates for those who can least afford it.
