I think these quotes from posters on another site sum it up nicely (note the thread was about the Nissan Leaf being used in Hawaii) I took the liberty of not quoting portions that were redundant or petty and I have no idea if these quotes are in thread or time order (mostly mixed them up some).
I say do Nukes and wind/solar/geothermal. The more the merrier. Of course some would object to wind turbines if it blocked their view of the ocean/scenery and some would object to geothermal (don’t want an ugly powerplant right next to Mauna Kea), and of course some would balk at paying for expensive solar cells and the expensive land to put them on… Well, on second thought, lets just put a nuke plant up.
Only one island, the Big Island, has active volcanoes. The Big Island is also, um, big enough to provide plenty of range anxiety. As Bertel says, yeah, you don’t want to be on the road to Hana (on the island of Maui) in a Leaf, either. Maui is also big enough that you wouldn’t want to be in an electric car.
The Leaf/Volt/plug-in Prius might work fine in Honolulu, but our electrical infrastructure is, in a word, lousy. Small incidents are enough to blackout the entire island. In 2006 an earthquake on the Big Island knocked out power on Oahu, 200-odd miles away.
We have the perfect site for a nuclear power plant, the deserted island of Kahoolawe, but the native Hawaiians would put up an epic fight. Our politicians might be dumb, but not that dumb.

You don’t need active volcanoes for geothermal.
My commute from Ala Moana to Waikiki is 1.8 miles. It takes 5 minutes at 5:30 AM and 20 to 25 minutes going home at about 3 PM. Most come into downtown Hono from 6 to 8 miles out. Some mornings it takes 45 minutes to travel that far, but at least 35% of the time it can take up to 2 hours if it is raining or an accident.
A bike seems like a good idea,but it rains a lot here, standing water and dodgy drivers, it’s good that speed limits are low. In my job I have to run out for meetings at many military bases. If timed wrong it can take hours. The traffic here is not the scale of LA, but the travel rate has to be lower. The average MPH on the cars computer is 15…..
Until I can refuel it in 15 minutes, no electric vehicle will meet my 3-car family’s needs
The 15-minute charge interval is an excellent vehicle selection criteria if you need to drive over 100 miles a day in that vehicle. If you don’t, EVs actually save you time because you never need to go to the gas station. An 8-hour charge interval isn’t the end of the world when the gas station is in your garage, in other words.
Hawaii, being geologically unstable, isn’t prime real estate for nuclear power plants.
I honestly don't know how much of an issue earthquakes and possible volcanic eruptions play into the safety equation of a nuclear plant.
Multiple posts mentioned the tourist factor (can't block the scenery with powerplants, windmills, solar panels), can't do tidal power in locations where surfers play as that is where a chunk of the tourist money comes from.
I suppose you could camouflage your geothermal plants? Put the Solar panels on roofs of existing buildings (avoid putting them on ground based arrays, avoid building new structures that mar the scenery). I could see off shore wind farms being doable but you'd have to be careful about placement (again the view, surfers, shipping, and such).
I'd have to assume any issues mentioned here probably hold true for most tropical islands from the Caribbean to the Pacific that can outlast a several meter sea level rise. With Geothermal being the least widely applicable solution.
