The heat and light provided by the sun provides an abundant source of energy for Hawai’i and can be harnessed in many ways.  Sunlight or solar energy generates hot water heating and electricity that can be used to power homes and other buildings.

Hawai’i has an endless supply of renewable wind power.  In ancient times, Hawaiians depended on the trade winds to help sail their canoes.  Today, one way we harness the power of the wind is through wind turbines which produce electricity.  In Hawai’i, wind farms are already supplying electricity to consumers on Maui and Hawai’i island and plans are under way to install wind turbines on Lana’i, Moloka’i, and O’ahu.

Sea:
