Hawaii, the Green Island

I have talked about the green efforts of Jeju Island, the biggest island of S.Korea, in E-gen couple of times. Today, I would like to introduce the biggest island of the U.S., Hawaii's green efforts to reduce the carbon foot prints. Hawaii has proclaimed that the islands will reach 40 percent renewable power by 2030. Not just that, the islands have tripled renewable energy capacity since 2005, while leading in creating renewable jobs. Most new homes in Hawaii have solar water heaters as well. The Hawaii's renewable energy sources are from Sun, Wind, Sea and Land.  The Sun's plentiful heat and light provide great source of energy. The most applicable sun related technologies adopted in the Hawaiian islands are photovoltaic systems, solar hot water and passive solar design and daylighting. These technologies have applied to homes and commercial buildings which result in huge savings in operation cost. Wind plays an important role in reaching the goal of 70% clean energy in Hawaii. Hawaiians say they have endless wind supply. Lanai and Molokai islands have the best wind levels in the country, and wind is available 40% of time there. Among the many benefits the wind energy can give, a lower impact of wind turbines on birds and other wildlife sets importance in the islands. Geothermal energy excavation had not started until 1960's. However, since its first drilling, geothermal energy makes up 20% of Hawaii's big island energy consumption.  Hawaii also explores the use of biomass energy from variety of sources. H-Power(Honolulu Project of Waste Energy Recovery), the city and county of Honolulu's "garbage to energy" plant burns refuse-derived fuel to provide electricity. Kaunai and Maui islands' sugar plantations produce biomass fuel for automobiles which is made from ethanol by sugarcane molasses mixing with gasoline. Today, the state Public utilities commission announced four rulings which push Hawaiian electric companies to reduce electricity costs and generate vast amount of renewable energy. While the states in mainland are struggling and fighting to reduce carbon foot prints, Hawaii moves ahead in executing green bills and applying green systems.
