I am moving to jamaica which is obviously a great place for solar. I have done lots of research on the solar thing, what i am trying to figure out is what kind of "earthship" or green home to build. Sand and bamboo is free, so i would like to utilize that. But there are plenty of resourses to use there also. I would love any suggestions and be very thankful. Also I need a plan to keep it cool, wich shouldnt be too bad because it will be a small  place.

Well, Earth Sheltering should help keep it cool(depending on ground temps), and provide a secure place during hurricanes. Solar can easily provide most of your hot water, and if needed your electricity(pricey).

Good Luck!
