Problems with re-newables in Hawaii are the same as other places, but they do have better opportunities: 1. The big island, Hawaii, has quite a bit of wind power, but they are at their limit (about 10%). If you go much higher then the system is unstable (wind changes speed quickly). 2. 20 years ago someone, maybe the utility, Helco wanted to put a geothermal plant on the island. Environmentalists stopped it. Just as well, a later eruption would have destroyed it. The big island is the only one that can use geothermal. 3. Maui may be getting some wind power in the near future. The only practical places to put it is on the big island and Maui which only have about 15% of the population. 4. Solar has a big disadvantage that most do not recognize. It will only save on fuel costs, and will not decrease generation facility expense and real estate area. You still have to have plenty of other generation capacity for when solar is not working. That capacity is partly idle during a bright sunny time. SOLAR REQUIRES BIG INVESTMENTS AND NOT JUST THE SOLAR CELLS. Solar PV is a long long way from being economical for general use.
