As an outlying island, Hawaii is working hard to develop renewable energy sources, including solar energy, wind energy, biomass and geothermal energy. Today, one of Hawaii's five homes has a residential rooftop solar panel. One-quarter of the electricity comes from renewable sources, but Hawaii is not just a source of power generation, it is also a pioneer in energy efficiency in theUnited States.
Hawaii has set a positive goal of 100% renewable energy supply in 2045. Hawaii is not only promoting wind energy, solar energy, energy storage, but also promoting energy conservation to meet the needs of rooftop solar power supply. Hawaii plans to be in 2030. Save 4.3 billion kWh of electricity a year, or about 40% more energy than 2007.
Hawaii has been selected by the Energy Services Coalition (ESC) for five consecutive years as a nation with a higher per capita amount of energy efficiency contract programs. In 1996-2016, a total investment of 442 million US dollars, per capita investment amounted to 325.25 US dollars, much higher than The national average of $53.93 is also far ahead of the second place in Kentucky, $172.84.
Hawaii invested $442 million in contracts with 225 buildings and facilities, a total of 96 million square feet of floor-top solar power. It is expected to save $1.1 billion in electricity bills during the contract period, saving 368,426 homes household electricity consumption for 1 year. These include a single, larger energy efficiency contract in theUnited States, with nearly 50% of all Hawaiian airports, with a total contract value of $158 million.
Hawaii is also actively promoting the Energy Building (ENERGYSTAR) certification. In 2016, 166 buildings in Hawaii have been certified, including 103 public buildings and 63 private buildings. The number of ENERGY STAR certified buildings has more than doubled compared to 2014. In 2016, the city of Hawaii boarded the US Environmental Protection Agency's Better Energy Star City Rankings. Honolulu City entered the 25th Energy Star City in the United States, ranked 22nd, and ranked 2nd in the medium-sized city, with 69 Energy Star Buildings. The total floor area of the building is 9.6 million square feet, saving $23 million in electricity bills annually.
From 2009 to 2016, Hawaii promoted the Hawaiian Green Enterprise Program (HAWAIIGREENBUSINESSPROGRAM) with more than 100 public and private companies, including rooftop solar power generation including hotels, commercial buildings, channels, restaurants, supermarkets, and large-scale gatherings, saving 18.532 million kWH power electricity, saved 94.4 million gallons of water and $4.967 million in energy bills.
In addition to the power sector, Hawaii has to achieve renewable energy and energy independence goals, and there is still a large area that needs to be actively addressed, that is, the transportation sector, Hawaii's road traffic, island aircraft and vessel flights, relying on a large amount of fossil fuels, so develop Electric vehicles are also a top priority. Hawaii is also one of the former states in theUnited States. By July 2016, there were 4,536 electric vehicles, with a monthly growth of 1.4% and an annual growth of 26.1%. Although it still only accounts for a very small number of vehicles, TheUnited Stateshas ranked second. At present, the number of electric vehicle charging stations has reached 531.
