Wind Power In Hawaii
Wind power in Hawaii has the potential to provide all of the electricity generation in the electricity sector in Hawaii. The 132 commercial wind turbines in the state have a total capacity of 236 MW. In 2015, wind turbines produced 6.4% of Hawaii's electricity. In 2012, Hawaii generated 367 million kWh from wind power. Hawaii began research into wind power in the mid-1980s with a 340 kW turbine on Maui, and the 2.3MW Lalamilo Wells wind farm on Oahu and the 9MW Kamaoa wind farm on the Big Island of Hawaii . The NASA wind turbines#MOD-5B, MOD-5B, a 3.2MW wind turbine, on Oahu was the largest in the world in 1987. These early examples were all out of service by 2010. Notable projects Operational Proposed wind farms Two developers have submitted proposals for three offshore wind farms. They are under review by the Bureau of Ocean Energy Management.

Hawaiian Hoary Bat
The Hawaiian hoary bat (''Lasiurus semotus''), also known as ''ōpeapea'', is a species of bat endemic to the islands of Hawaii. Whereas the mainland hoary bat (''L. cinereus'') is found throughout North America, the Hawaiian hoary bat is distributed only among the major volcanic islands of Hawaii, making it the only extant and native terrestrial mammal in the state; although some studies also posit that the mainland hoary bat lives in sympatry on the Hawaiian Islands alongside the Hawaiian hoary bat, this has been disputed. The Hawaiian hoary bat was officially named the state land mammal of Hawaii in 2015. It is a federally listed endangered taxon of the United States. Like many species of bats, Hawaiian hoary bats are brown in color. However they are distinguished by the silver coloration that ‘frosts’ the fur on their back, ears, and neck. They typically weigh between 14 to 18 g (0.49 to 0.63 ounces), and have a wingspan of about 10.5 to 13.5 inches, with females being l ...

Wind Power In The United States
Wind power is a branch of the energy industry that has expanded quickly in the United States over the last several years. From January through December 2021, 379.8 terawatt-hours were generated by wind power, or 9.23% of electricity in the United States. The average wind turbine generates enough electricity in 46 minutes to power the average American home for one month. In 2019, wind power surpassed hydroelectric power as the largest renewable energy source in the U.S. As of January 2022, the total installed wind power nameplate generating capacity in the United States was 135,843 megawatts (MW). This capacity is exceeded only by China and the European Union. Thus far, wind power's largest growth in capacity was in 2020, when 16,913 MW of wind power was installed. Following behind it were 2021, during which 13,365 MW were installed, and 2012, which saw the addition of 11,895 MW, representing 26.5% of the new power capacity installed during that year.

Energy In Hawaii
Energy in the U.S. state of Hawaii is produced from a mixture of fossil fuel and renewable resources. Producing energy is complicated by the state's isolated location and lack of fossil fuel resources. The state relies heavily on imports of petroleum. Hawaii has the highest share of petroleum use in the United States, with about 62% of electricity coming from oil in 2017. As of 2021 renewable energy made up 34.5% . Hawaii has the highest electricity prices in the United States. As of 2016 the average cost of electricity was $0.24 per kilowatt-hour, followed by Alaska at $0.19. The U.S. average was $0.10. Consumption Hawaii's energy consumption is dominated by oil, which in 2016 provided 83% (down from 85.0% in 2008 and 99.7% in 1960). Other sources in 2016 included coal (5.6%) and renewable energy (11.2%).

Solar Power In Hawaii
The energy sector in Hawaii has rapidly adopted solar power due to the high costs of electricity, and good solar resources, and has one of the highest per capita rates of solar power in the United States. Hawaii's imported energy costs, mostly for imported petroleum and coal, are three to four times higher than the mainland, so Hawaii has motivation to become one of the highest users of solar energy. Hawaii was the first state in the United States to reach grid parity for photovoltaics. Its tropical location provides abundant ambient energy. Much of Hawaii's solar capacity is distributed solar panels on individual homes and businesses. Hawaii's grid has had to deal with this unique situation by developing new technology for balancing the energy flows in areas with large amounts of solar power. In 2017 distributed solar produced 913GWh which was 36% of all renewable energy produced in the state and about 9% of electricity sales. Utility-scale solar produced 212GWh, just over 1% o ...

Floating Wind Turbine
A floating wind turbine is an offshore wind turbine mounted on a floating structure that allows the turbine to generate electricity in water depths where fixed-foundation turbines are not feasible. Floating wind farms have the potential to significantly increase the sea area available for offshore wind farms, especially in countries with limited shallow waters, such as Japan, France and US West coast. Locating wind farms further offshore can also reduce visual pollution, provide better accommodation for fishing and shipping lanes, and reach stronger and more consistent winds. Commercial floating wind turbines are mostly at the early phase of development, with several single turbine prototypes having been installed since 2007. , there are 3 operational floating wind farms. The first is the 30 MW Hywind Scotland with 5 floating turbines, developed by Equinor ASA and commissioned in October 2017. History The concept for large-scale offshore floating wind turbines was introduce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Offshore Wind Power
Offshore wind power or offshore wind energy is the generation of electricity through wind farms in bodies of water, usually at sea. There are higher wind speeds offshore than on land, so offshore farms generate more electricity per amount of capacity installed.Madsen & KrogsgaardOffshore Wind Power 2010 ''BTM Consult'', 22 November 2010. Retrieved: 22 November 2010. Offshore wind farms are also less controversial than those on land, as they have less impact on people and the landscape. Unlike the typical use of the term "offshore" in the marine industry, offshore wind power includes inshore water areas such as lakes, fjords and sheltered coastal areas as well as deeper-water areas. Most offshore wind farms employ fixed-foundation wind turbines in relatively shallow water. As of 2020, floating wind turbines for deeper waters were in the early phase of development and deployment. As of 2020, the total worldwide offshore wind power nameplate capacity was 35.3 gigawatt (GW). Unite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaii Wind Resource Map 50m 800
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protec ...

Honolulu City Council
Honolulu City Council is the legislature of the City and County of Honolulu, the capital and largest city in Hawai'i, the fiftieth state in the United States. The City and County of Honolulu is a municipal corporation that manages government aspects traditionally exercised by both municipalities and counties in other states. Each of the nine members of its City Council is elected to a four-year term and can serve no more than two consecutive terms. Council members are elected by voters in nine administrative districts that, since 1991, are reapportioned every ten years. Like the Honolulu mayor, members of the City Council are elected via nonpartisan elections. Enacted in 1973, the City and County Charter establishes the council's legislative power and responsibility for Honolulu County, including its budget, public safety, zoning and municipal development, and other governmental affairs.
