Big Island major producer of geothermal energy
The volcanic origins of our islands make Hawai‘i an
ideal place for the production of geothermal energy. The
word geothermal comes from the Greek word “geo” meaning
earth and “thermal” referring to heat, thus;
geothermal energy is derived from heat within the earth.
Because our islands are young in geological terms, the resources
necessary for geothermal production can often be found less
than a mile below the surface. [More]

Marine ornamental aquaculture: pursuing the yellow tang
In Hawai‘i we are surrounded by beautiful
ocean and coral reefs which contain a vast array of colorful
wildlife. Recently, more and more people here, and around the
world, have aimed to recreate a small piece of this amazing
environment in their homes by maintaining marine aquaria. This
increased appreciation for coral reefs, and the colorful fish
that dwell among them, has led to a billion dollar industry
that could ultimately undermine the environment that originally
inspired it. [More] |
The flame angelfish is the first success
of OI’s coral reef ornamental breeding programs.
