To implement sustainable development, we need to use renewable energy. Currently the most useful renewable energies are solar and wind power. These are major resources of renewable energy in Europe and commercialized.
Awajishima is one of the most advanced areas in Japan to use the renewable energy. You will see solar panels and wind fans everywhere on the island. In Awajishima you can see canola blossoms everywhere. From the flower seeds canola oil is extracted. The oil is converted to alcohol and used for biofuels of cars. This experimental factory is set at the Wellness park area of Goshiki town.
There is some potential energy in the Naruto whirlpools as well. High-speed tidal currents caused by the difference of tidal levels cause rapid movement of the sea current in the Naruto channel, leading to electric power generation. This type of power generation is available in South Korea. Naruto whirlpools have a high potential for the power generation, but it has a big potential as tourism business as well. Since a big movement of Awajishima residents exists to support that the whirlpools be recognized as a world heritage site, it might not become real.
