State officials issue evacuation orders as Hawaiian wildfire threatens hundreds of homes — ripping through over a mile of land
Not even a year after a historic wildfire that devastated the island of Maui in Hawai’i, residents on another of the state’s islands were put under an evacuation order earlier this week as a blaze put around 200 homes at risk.
What happened?
The rural island of Kauai witnessed a huge wildfire between Hanapepe and Kaumakani that put residents and businesses at risk.
According to the Guardian, firefighters were able to contain the blaze, but 1.56 square miles of land was destroyed, as well as one building.
The incident would have been triggering for the island nation’s residents, who would have been aware of and likely affected by the wildfire on Maui in August 2023, which killed over 100 people and displaced thousands. Approximately 3,000 buildings were destroyed, too.
Why is this wildfire event so concerning?
Considering the damage caused on Maui, the threat of wildfires is all too real for Hawaiians.
According to analysis from Clay Trauernicht for the University of Hawai’i, shared by NBC News, fire frequency has been rising since the 1990s. The outlet’s report noted that as much land has been burned on the island in the last five years as the previous 20 combined.
Allyson Earl, a fire researcher for the Hawai’i Wildfire Management Organization and the University of Hawai’i, told the publication that frequent and large fires are “now our new normal.”
With Hawaiian islands now featuring more flammable grasses because of invasive species and dry seasons becoming longer and drier as a result of global heating, these threats will only magnify if not dealt with appropriately.
What’s being done to prevent wildfires?
According to NBC News, wildfire preparations are being taken more seriously by the state, while organizations are trying to get the spread of flammable, invasive grasses under control — despite pushback from some landowners.
On a macro level, we all need to reduce the production of planet-warming pollution. Pollution exacerbates extreme weather events that increase the likelihood of wildfires, such as droughts.
We can achieve that by relying less on gas-guzzling cars, switching to pollution-free sources of energy, and by curbing our consumption of meat — which contributes to both high levels of pollution and results in land loss for the purposes of livestock grazing.
Wildfires aren’t just a risk to Hawaiians, either. They are a worldwide issue, from the Americas to Europe, and Asia to Oceania. We should all be concerned about our role in making them more common and severe, and making small lifestyle changes can deliver huge results.
For example, a study from clothing reseller ThredUp found that 22.8 kilograms of carbon dioxide equivalent can be reduced for every pound of clothes bought secondhand.

Celebrations across Hawaii to take place in honor of Sakada Day
HILO (HawaiiNewsNow) – Hawaii Island will commemorate the arrival of the first 15 Filipinos to Hawaii back in 1906.
A free Sakada Day Celebration in Hilo will take place on Dec. 20, from 9 a.m. to 1 p.m. to honor the contributions of the Filipino plantation workers who sparked a wave of migration.
“Filipinos are actually a large group here in Hawaii, lot of times things like this are actually tend to be a little neglected,” said Iris Viacrusis, co-chair of the Sakada Day Celebration.
This year’s event will feature a lei presentation at 9 a.m. at the statue at Keaau Community Center, followed by lunch, entertainment and a presentation to three descendants of sakadas: Sandra Claveria, Lorraine Rodero Inouye and Angel Pilago.
Two exhibits will also be displayed for guests to learn more about the sakadas — one will feature stories of the sakadas’ legacy and the other will showcase cultural items and clothing from Viacrusis’ collection.
Dec. 20 was proclaimed Sakada Day under Gov. David Ige in 2015.
Event organizers are preparing for next year’s 120th anniversary of the sakadas in Hawaii.
Meantime, on Oahu, a free Sakada Day Celebration is taking place today, Dec. 13, at Hawaii Plantation Village in Waipahu from 10 a.m. to 2 p.m.
The Philippine Celebrations Coordinating Committee of Hawaii, the University of Hawaii at Manoa Center for Philippine Studies and Filipino Curriculum Project organize the annual gathering, which honors the resilience, contributions, and cultural legacy of sakadas, migrant plantation workers whose hard work, courage, and spirit continue to shape the Filipino American experience today.
High school students will take part in stage performances, visual presentations, education booths and a fashion show.

University of Hawaii at Manoa and Lawrence Berkeley National Laboratory Teamed up To Analyze Feasibility of Geothermal Cooling Technologies
By Justin Daugherty, NLR
In areas with geologically recent volcanic activity and ample underground water flow, like the Hawaiian Islands, geothermal energy technologies present options to augment the electric grid.
To investigate building cooling and energy efficiency options, the University of Hawaii at Manoa’s Hawaii Groundwater and Geothermal Resources Center collaborated with scientists at Lawrence Berkeley National Laboratory through the U.S. Department of Energy’s Energy Technology Innovation Partnership Project (ETIPP).
Managed by the National Laboratory of the Rockies (NLR), formerly known as NREL, ETIPP supports remote, coastal, and island communities with technical assistance and energy planning to help them build more reliable and affordable energy systems. Communities apply for up to 24 months of technical assistance, and those communities drive the scopes and focuses of their energy projects.
University of Hawaii at Manoa joined the program in 2022 with a desire to explore geothermal options, and a new report from this project details the feasibility of developing shallow ground heat exchangers (GHEs) across Oahu and at a specific site on the island for cooling.
Geothermal heat pumps take advantage of relatively constant temperatures just under the earth’s surface, using GHEs to exchange heat with the earth. Through a system of looping pipes in the shallow ground, GHEs can move heat from a warm place to a cooler place, like how a refrigerator functions.
“High-temperature geothermal, which requires deep drilling, is required to produce electricity, but low-temperature geothermal such as GHEs, which can be accessed much nearer the ground surface, can be used for building heating and cooling, greatly lessening loads on the electric grid,” said Lawrence Berkeley National Laboratory’s Christine Doughty, staff scientist.
“I believe both types of geothermal have potential to be an asset to Hawaii,” added Nicole Lautze, founder and director of the Hawaii Groundwater and Geothermal Resources Center.
Determining Geothermal Cooling Favorability in Hawaii
In open-loop geothermal systems, wells are drilled to extract and inject groundwater, allowing the movement of thermal heat to and from the earth. These GHEs use cooler ground water from outside the system for the cooling process and expel the warmer water afterward.
In contrast, closed-loop GHE systems continually circulate a heat-transfer solution through pipes, which transfers heat to and from the ground via thermal conduction. Groundwater needs to have temperatures that are low enough to effectively cool buildings, and groundwater flow in a GHE system works to remove built-up heat.
Hawaii has far greater needs for cooling than for heating—meaning that GHEs would add heat to the subsurface and cause the systems to not function as desired. That is where groundwater comes in: It replaces heated water from the boreholes and maintains the functionality of the GHE system. Sufficient groundwater flow, then, is essential to the considerations for GHE deployment. GHE systems may not be deployed in areas with restricted watersheds or where there is subsurface production of freshwater. Therefore, closed-loop systems may be a more reasonable option in some locations.
Numerous factors help determine whether a community or business may consider GHEs. Areas with older homes may lack efficient energy systems, and some organizations, like schools or government buildings, may prioritize more adaptive heating and cooling. Cultural considerations are also very important, and a new NLR report incorporates Hawaii communities’ perspectives on geothermal.
Economic factors are another big consideration, with the expense of deploying a system versus energy savings playing into overall cost. Modeling revealed that electricity and energy transfer demand decreased, and such reductions contributed to cost savings. Longer loan terms may help ease deployment expenses for geothermal systems.
ETIPP researchers factored the above parameters into their analysis to develop favorability maps for closed-loop and open-loop GHE systems. They used specific geographic information system layers with 11 attributes—including elevation, geology, and soil permeability—to develop an overall favorability map for GHEs on Oahu.
For the site-specific feasibility analysis at the University of Hawaii at Manoa’s Stan Sheriff Center, researchers used a hydrogeologic model to analyze groundwater flow of a closed-loop system at the site. Restrictions on water quality—mandating that groundwater must be left in its natural state—diminished the available area for GHE system deployment across the island, while many coastal areas showed high favorability. Overlays showing potential customers and restricted areas sharpened the maps.
Geothermal Cooling Potential at University of Hawaii at Manoa
From the island-wide analysis, ETIPP analysis homed in and found that the Stan Sheriff Center at the University of Hawaii at Manoa, a building with a high cooling load in an area with lots of open space surrounding it, could make a good candidate for site-specific analysis of GHE technology.
Researchers used a hydrogeologic model to analyze a potential closed-loop system at the site. They modeled groundwater and heat flow, analyzed subsurface heat flow, and completed a techno-economic analysis.
Analysis without groundwater flow showed that the GHE system may operate normally in the first year, but heat buildup would increase water temperatures significantly after that, and without groundwater to sweep heat away, there would be increased chiller demand in years two through six. Modeling that incorporated groundwater flow—with similar conditions as the Stan Sheriff Center—showed that heat would be effectively swept away from the borefield, which would enable successful GHE operation for at least 10 years. Thus, including groundwater in analysis and planning—coupled with low interest loan rates and high capital investment—may provide economic benefits to the university.
Cold seawater may be an option for cooling-source systems, the analysis concluded, and such a system already operates at the Natural Energy Laboratory of Hawaii. The report authors encouraged further study.
As in Hawaii, ETIPP continues to help communities explore geothermal and other technologies to help meet their energy needs through in-depth, collaborative investigation of potential solutions.
“This ETIPP project established a strong collaboration with LBNL and the foundation for what I hope is additional grant funding to explore the potential of GHEs on the UHM campus and across the state to cool buildings and reduce load on Hawaii’s grid,” Lautze said.
The U.S. Department of Energy’s Energy Technology Innovation Partnership Project (ETIPP) is a community-led technical support program for coastal, remote, and island communities to access unique solutions and increase energy reliability. By uniting federal agencies, national laboratories, regional organizations, and community stakeholders, ETIPP provides tailored technical support to help communities achieve affordable, reliable solutions to their energy system challenges. This collaborative model leverages the combined expertise and resources of its partners to deliver comprehensive, practical solutions that align with local needs. Learn more about ETIPP.
