From Audubon (Karyn Stockdale):
Last year was difficult. And while 2021 presents some optimism for a better world, the intense challenges we face remain—COVID-19 and other public health crises, growing drought and climate change, and racial injustice. Each of these intersect with water.
More than 90% of climate stress is experienced through the water cycle—drought, extreme weather and flooding, wildfire, and more. These issues were starkly illustrated in 2020 with the wildfires in the West and the drying of several western habitats. Audubon’s own science shows that climate change is by far the biggest threat to the birds that we love. We can’t ignore the relationship between water and climate—and the dangers climate change presents to our communities, often in inequitable ways. Solutions to these problems will require elected officials to catch up to what most Americans already know: we need to prioritize our water future with bold action and funding.
In 2021, our job is to galvanize a heightened focus on water to advance solutions that improve the lives of people and birds in the West. Our commitment to collaborating with water users, tribes, farmers, water and land managers, and other stakeholders allows us to identify solutions that align habitat protection and restoration with improved water supplies for communities. And with your support, we can better protect and restore the Colorado, Gila, Rio Grande, San Joaquin, and other rivers in the arid West as well as unique saline lake ecosystems such as Great Salt Lake and the Salton Sea.
The Colorado River Compact was signed 99 years ago, and the year ahead kicks off a new round of negotiations about the future of the river. This moment gives all of us opportunities to lean into the lessons learned from management of the Colorado River and its water and bring environmental priorities forward. Of course, the past two decades have required more adaptation and mitigation because of dwindling water resources amidst long-term drought. As the arid West continues to deal with climate change, our laws and management will need to adapt.
With your advocacy, we can advance Audubon’s Western Water policy priorities with considerations for inclusive and equitable provisions. We can leverage opportunities for federal legislation and appropriations to address drought in the West, WaterSMART improvements, Farm Bill funding, and more in the context of declining water flows due to climate change impacts. We can advance investments in natural infrastructure and climate resiliency (i.e. floodplain restoration, natural water storage solutions, wildfire mitigation programs). We can improve river health, protect water quality, and support funding for agencies focused on water resources and habitats through state policy improvements. And in priority areas, we will work on-the-ground and with partners to protect and restore bird habitat and improve water flows.
For urgent attention to solutions that last, we need diverse and inclusive voices at the table and in decision-making. Audubon has spent years working to improve our equity, diversity, and inclusion efforts, and 2020 gave us real urgency to address the disproportionate impacts that Black, Indigenous, and People of Color face, including water security. In 2021, Audubon’s Western Water team will better support tribal communities, when asked for help, because tribes should be able to actively participate in decisions about water management, ensure that their water needs are met, and realize the full benefits of their water rights. And we’ll better evaluate what communities are most impacted by our conservation actions, and build collaborative partnerships to increase bird habitat and equitable access for people.
Birds connect us. Water is our great unifier too. Join us in taking urgent local, state, and national actions in the year ahead. Sign up, spread the word, and stay connected at http://audubon.org/westernwater.
From The Telluride Daily Planet (Candy A. Meehan):
In 1888, local farmers and ranchers got together to start a formal ditch company. For this, there would have to be an official survey. The original survey map that was made in July through August of 1888 was measured by hand with 100-foot links of chain. Once completed, the Lone Cone Ditch Company was formed on Wright’s Mesa for irrigation purposes on July 30, 1889.
Shortly after that, on Oct. 29, 1889, the State of Colorado awarded its certificate of incorporation. The original eight owners of the Lone Cone Ditch Company were Roger Williams, Charles Hotchkiss, Charles Traux, Jeremiah Foster, R.A. Peers, J.W. Winkleman, L.W. White and J.W. Fraser.
Approximately 12 to 13 years later, land was donated for a reservoir. The company took the opportunity to grow, and the Lone Cone Ditch Company then became the Lone Cone Ditch and Reservoir Company on June 21, 1902. The reservoir was excavated using a Fresno machine pulled by horses. The reservoir floor was compacted after excavation by running a sheep herd back and forth through it. It was built to hold 1,800-acre feet of water…
Every year, the size of the water shares depends on Mother Nature. Snowmelt, rain, wind and heat all contribute to the factors of water dispersed to each shareholder annually. Lone Cone Ditch does not have a ditch rider. Given that there are approximately 14 miles of upper ditch and 32 miles of lower ditch, water shares are taken on an honor system with divider boxes made and placed by each shareholder. This ditch system is not an “on call” system. It is “all on” or “all off.”
According to Colorado SNOTEL Snowpack Update report for Jan. 24, the Lone Cone is at 6.1 inches of water and 64 percent of it median. These numbers are low and could be an indicator of what our water circumstances could be for the upcoming irrigation season. Conservation practices can become highly effective habits.
The Lone Cone Ditch and Reservoir Company is currently working on the mechanics of the dam structure that is in need of maintenance and repairs. Their engineer is diligently completing his assessment and report. The existing water outlet has held strong and true for many, many years. But, like with all things, it is in need of replacement. At that time, regular maintenance will be performed to ensure that it is functioning to capacity. Once the assessment is complete, grant funding will be the next step.
One of the most profound statements I have ever heard before was from a Wright’s Mesa farmer and rancher: “Gold runs clear.”
From The High Country News [December 21, 2020] (Mark Olalde):
Decades have passed and millions of dollars spent, yet little has been done to restore the lake. California officials say it’s all been leading up to this moment.
This story is a collaboration between High Country News and The Desert Sun, part of the USA Today Network.
Red flags flutter outside the schools in Salton City, California, when the air quality is dangerous. Dust billows across the desert, blanketing playgrounds and baseball diamonds, the swirling grit canceling recess and forcing students indoors. Visibility is so poor you can’t see down the block. Those days worry Miriam Juarez the most.
Juarez, a mother of three and active volunteer at the schools, often received calls to pick up her 7-year-old son, Lihan, when sudden nosebleeds soiled his outfits. But she couldn’t leave her job, harvesting vegetables in the fields that form square oases in the Coachella Valley. So she began packing fresh clothes for him every day, before COVID-19 halted in-person learning. “It’s OK. Just go to the office,” she’d say. “The ladies will help you change.”
The doctor’s diagnosis was unclear: Perhaps Lihan had allergies. Then, Juarez’s 17-year-old daughter began suffering headaches and respiratory issues. Finally, Juarez got a runny nose and sore throat that lasted for days when the dust blew.
Juarez blames California’s largest lake, the Salton Sea. Only a few miles east of the family’s neatly kept house, it’s a cobalt-blue patch on Southern California’s Colorado Desert, a roughly 325-square-mile oblong oddity that’s twice as salty as the ocean.
It’s also toxic — a looming environmental and public health disaster. The Salton Sea’s shoreline is receding, exposing a dusty lakebed known as the “playa.” This sandy substance holds a century’s worth of agricultural runoff, including DDT, ammonia, possibly carcinogenic herbicides like trifluralin and other chemicals. Its windborne dust travels across Southern California and into Arizona, but nearby communities — many of them populated by Latino farmworkers — bear the heaviest burden.
The problem isn’t new. Yet California, though largely responsible for fixing it, has barely touched the more than 25 square miles of exposed playa. It’s been almost two decades since an agreement was signed in 2003, committing the Imperial Irrigation District, the Colorado River’s largest user, to conserve water that once flowed from farms into the lake and send it to other districts. Knowing the lake would recede, the state committed to mitigating the health and environmental impacts. The state and federal governments have spent about $70 million so far, largely on salaries and studies. Meanwhile, the high-water mark has fallen nearly 10 feet, and salinity continues to rise.
The politicians admit they’re years behind schedule, but they’re adamant that the course has been corrected, the money is being put to good use and the future is bright. Currently, 16 state employees are planning projects to tamp down dust or rebuild wetlands, and that will grow to 26 once new positions approved in the latest budget are filled. They’ve also nearly finished permitting projects that will cover 30,000 acres, a little more than a third of the area that could eventually be exposed.
Assembly Member Eduardo Garcia, D-Coachella, who represents the region surrounding the lake, is optimistic. “I believe 2021 will be a new story of the state of California living up to its responsibility and liability in terms of investing in what it signed up for at the Salton Sea,” he said.
Still, the state must overcome funding issues, disagreements with the feds, permitting bottlenecks and decades of inertia.
FOR YEARS, the government stood still.
Over tens of thousands of years, as it meandered across the West, the Colorado River occasionally filled the Salton Sea. The lake’s most recent iteration formed between 1905 and 1907, when an engineering disaster diverted the river into the basin. It has since been fed largely by agricultural runoff from the Imperial and Coachella valleys. It soon became clear that salinity levels would continue increasing. Since then, millions more people have begun relying on the Colorado River, even as climate change threatens the waterway. In response to competing demands, the 2003 agreement diverted water from the Imperial Valley. That meant that the lake’s level was guaranteed to drop. So, in 2007, the state released a sweeping proposal with an $8.9 billion price tag — unfortunately, just as the Great Recession took hold. “Folks got sticker-shocked and did not really pursue a full rehabilitation-restoration approach,” Garcia said.
Still, the agreement included 15 years of inflows to temporarily control salinity while the state decided on a plan. By late 2020, the California Natural Resources Agency had completed one dust-suppression project covering a mere 112 acres; the goal for the end of that year was 3,800 acres. “For a very long time, the enormity of the challenge at the sea was frankly overwhelming, and there was very little action at the state level until 2014 or 2015,” said Wade Crowfoot, secretary of the Natural Resources Agency, the lead department tasked with restoring the sea.
That one completed site, the Bruchard Road Dust Suppression Project, looks like someone tried to farm the surface of the moon. Tractors dug long, straight furrows through the white, sandy playa to catch the windblown dust. But more expensive wetland habitat restoration is needed; the lake has long been an important feeding ground along the Pacific Flyway, a migratory bird route on the Western Seaboard.
In order to “fix” the sea, government agencies, led by the state, will need to flood, plough or plant tens of thousands of acres to control dust and rebuild habitat. They’re racing against the clock. An estimated 131 square miles of playa will be dry and exposed to the air by the time the lake reaches a degree of equilibrium — meaning the inflow from three small waterways and agricultural runoff will maintain a smaller lake — in 2047.
For a shallow body of water, the Salton Sea holds a large amount of sunk costs. Years of studies, salaries and office supplies have been purchased, but few shovels have been put to work.
But Arturo Delgado, an assistant secretary with the Natural Resources Agency and the state’s Salton Sea czar, pointed out that a portion of the more than $355 million set aside for the lake — 99% of it from bonds — needed to be spent sorting out permits and access to a complex checkerboard of state, tribal, federal and private land. “The bulk of the funding that has been appropriated to date for the Salton Sea program has not been spent,” he said.
As of late November, state agencies had used about $53 million, most of it going to ledger entries, including “studies and planning activities,” “staffing and other design costs” and “annual surveys to monitor bird and fish populations.” Glaring zeros marked the “expended” column next to several construction budgets.
Years of indecisiveness mixed with land-access and permitting issues have bogged down the process; the state’s own efforts to clean up the ecological disaster got stuck in the compliance process. “Frankly, the permitting is probably more expensive right now than the actual projects,” said Tina Shields, water department manager at the Imperial Irrigation District, which, separate from the state, completed about 2,000 acres of dust suppression on its own land around the lake.
The state is appropriating some funds, but the federal government has been slow to pitch in. The U.S. Department of Agriculture kicked in about $8 million for dust-suppression projects, and over the past five years, the Bureau of Reclamation spent about $11 million on water-quality monitoring, wetlands projects along polluted rivers that empty into the lake, and studies on the feasibility of using salty water for dust mitigation.
When the Natural Resources Agency is finally ready for large-scale builds, the budget could get in the way. Individual construction sites are expensive, with one roughly 4,000-acre project set to break ground in 2021 costing an estimated $200 million. Another 160-acre design will cost $20 million. Cleanup along the New River, one of three small waterways flowing into the lake, comes with a $28 million bill.
And while California regularly calls on bonds to fund large projects, that money can’t be used for operations and maintenance. Crowfoot acknowledged that the state lacks a mechanism to fund long-term monitoring and upkeep. At the beginning of 2020, Gov. Gavin Newsom promised an additional $220 million, but that was predicated on a bond. When the pandemic hit, that idea and a parallel measure Garcia introduced in the Legislature both died, although Garcia said he’ll reintroduce his bill in 2021.
For now, the state lacks a better funding plan. “We don’t have the reserves that we had prior to COVID-19,” Garcia said. “That money has been invested in our emergency response.”
IF THE SALTON SEA RESTORATION were to reinvigorate the Pacific Flyway, it would likely begin at the wetlands around Red Hill Bay on the lake’s southeastern corner, where various agencies are constructing new habitat. An October visit found it far from inspiring. A flat patch of dirt covered several hundred dry acres, dotted with a few dead trees. A sign, complete with typos, showed a hopeful rendering of a functioning wetland and promised: “Estimated construction in 2016.”
Rep. Raul Ruiz, D-Calif., introduced the federal Salton Sea Public Health and Environmental Protection Act in November to streamline permitting and unlock additional federal dollars. He acknowledged the delays, but called the Red Hill Bay Restoration Project “proof of concept that we can get a shovel-to-ground project started,” adding, “My number-one goal was to break ground on a project to rip that inertia to pieces and to start building momentum.”
The son of farmworkers, Ruiz grew up just miles from the lake. He returned home to practice medicine after studying at Harvard, and he still wears gym shoes with his suits, as if he’s about to run into the emergency room. Ruiz, who was struck by the high rates of respiratory illnesses in the area, compares the lake to a patient “in need of triage.”
A 2019 study conducted by researchers from the University of Southern California’s medical school and a local nonprofit called Comite Civico del Valle estimated that nearly one in four elementary school children in northern Imperial County, the area nearest to the Salton Sea’s exposed and emissive playa, suffered from asthma, about three times the national average. “Exposing this population to more and more poor air quality — in particular, particulate matter small enough to penetrate the lung-blood barrier that also carries toxins like arsenic, selenium and pesticides — would be devastating to the public’s health,” Ruiz said.
Ruiz said that divergent visions had stalled progress, while egos got in the way. Since entering Congress in 2013, he has tried to rally local lawmakers and called on the federal government to take a more active role. Juarez, in Salton City, welcomes the efforts but believes that if this problem affected a wealthier, whiter area like Palm Springs, it would’ve been addressed already. It’s a sentiment her elected representatives share. So, she asked, “Why is nothing getting done?”
In 2020, the Imperial County Air Pollution Control District slapped the state and feds with notices of violation for failing to complete dust-control projects. The Imperial Irrigation District wants the state to act, too, citing the 2003 water transfer agreement. California politicians argue the federal government needs to step up because the Bureau of Reclamation owns much of the land underneath the lake. The feds insist they occupy a supporting role, and agency heads from Reclamation and the U.S. Fish and Wildlife Service refused to attend a September congressional hearing to discuss the government’s role in cleaning up the lake.
The people in Salton City and other towns around the retreating lake are still waiting. For Juarez, who began working in the fields when she was just 15, the clock is ticking on the American dream her family built in the California desert. It’s difficult to find hope in stepwise permit approvals while dust fights through cracks in her home. She takes her children to the doctor every six months and worries about Lihan. “I’m nervous, and I’m scared to see my son like that,” Juarez said.
She doesn’t want to move away but is finally considering it. “I don’t want to stay here and see my kids sick,” she said.

From The Mountain Town News (Allen Best):
Plan for Yampa Valley filed with fed agency
Conceptual work has begun on a pumped-storage hydro project along the Yampa River five miles east of Craig. The project was conceived to provide electricity to assist Colorado utilities in balancing the intermittency of wind and solar generation as they advance toward 100% renewable portfolios during the coming decade.
In pumped-storage hydro, water is released from a higher reservoir to produce electricity when needed most. The water in the lower reservoir is then pumped uphill to the higher reservoir when electricity has become more readily available.
Colorado has two existing pumped-storage hydro projects. Cabin Creek Generating Station, between Georgetown and Guanella Pass, harnesses a 1,200-foot vertical drop to produce up to 324 megawatts of electricity. Completed in 1967 and operated by Xcel Energy, it serves as effectively a giant battery with a four-hour life, the same as a humongous bank of Tesla batteries.
Near Leadville, at Twin Lakes, the Mt. Elbert pumped storage hydro plant can produce up to 200 megawatts. Operated by the U.S. Bureau of Reclamation, that pumped-storage hydro was completed in 1981.
Near Craig, the project—it’s really no more than an idea—would use three turbines to produce 600 megawatts, nearly as much as Colorado’s largest coal-fired power plant. The idea submitted to the Federal Energy Regulatory Commission on Aug. 20 calls for two relatively small reservoirs of storage capacity of 4,800 acre-feet each connected via a tunnel and conduit, with a total drop of 1,450 vertical feet. This compares with a 1,200 drop at Cabin Creek.
The lower reservoir would not be on the Yampa River, nor would it require a constant infusion of water. Rather, it operates in a closed loop. Only water lost to evaporation would have to be replaced. In an open loop hydro system, water is drawn directly from a river to be pumped uphill.
Matthew Shapiro, the applicant, says the preliminary permit awarded by FERC in November for the Craig-Hayden project is best described as a placeholder for a future license application. He hopes to begin producing electricity toward the end of this decade, just as several utilities in Colorado aim to achieve 100% renewable generation. See Nov. 24 notice in the Federal Register.
Creating pumped-storage hydro, he says, requires considerable patience but also capital. One project in Wyoming that Shapiro’s company proposes has an estimated cost of $1.8 billion.
The United States has not had a new pumped-storage project since 1993. The Craig-Hayden project is the only FERC filing for Colorado.
Meeting the checklist
Despite its jumbled geography and abundant water, the Centennial State actually is a difficult place for new pumped hydro projects, says Shapiro. The right kind of topography, with enough vertical drop over a short distance but not too much is needed, but also proximity to transmission and low environmental sensitivity.
“It’s a significant challenge. Finding the combination of factors is not easy,” Shapiro says. “But that is what a good pumped-storage developer does during the site-screening process.”
The Craig site checks all the boxes. Private land is easier to develop than public land, says Shapiro, and it has that. Transmission lines export the electricity in three directions and to several states, but especially to east of the Continental Divide in Colorado. The Hayden and Craig coal-fired stations together have 1,724 megawatts of generating capacity, the most of any area of Colorado.
Water is also needed. The two coal-burning stations together own 15,000 acre-feet from the Yampa River, far more than the 5,000 acre-feet needed for this project. The plants will close between 2025 and 2030.
Finally, a pumped-storage hydro project needs customers. Shapiro reports seeing a promising market within Colorado. Two utilities—Platte River Power Authority, a co-owner of the Craig plant, and Holy Cross Energy—both have adopted goals of 100% renewables by 2030. Xcel Energy, the primary owner of the Hayden units and a part owner at Craig, has a 100% emissions-free goal for 2050.
All analyses of attaining high levels of renewables in electricity supplies have focused on three crucial pillars:
One, demand needs to be recontoured to better take advantage of when renewables are abundant, such as linking warming of hot water to times of abundant electricity.
Second, energy supplies in Colorado need to be better connected with a broader geographic area, either to the west or possibly to the Great Plains and conceivably in both directions, thus allowing greater ability to take advantage of renewable energy. The sun might not be shining everywhere, but the wind is always blowing somewhere. There is actually some predictability to this, if you get large enough terrain.
And third, there needs to be storage. The Craig-Hayden idea envisions eight-hour storage, compared to the four-hour value of lithium-ion batteries. So-called green hydrogen, which uses renewable electricity to create hydrogen from water, can deliver 50 to 100 hours of storage, but the technology and economics lag. “I think there is going to be a mix, particularly over the next 20 to 30 years before I think green hydrogen really matures,” says Shapiro. “We will see a mix of storage types. I don’t think we are going to do 100% renewable energy without additional advanced energy storage technology.”
Utilities have been closely watching developments. Duane Highley, chief executive of Tri-State Generation and Transmission, operator of the three units at Craig, said on an October webinar that his utility sees no need to make decisions about energy storage until 2024 and does not actually need it until 2029-2030. The three units at Craig will be shut down between 2025 and 2030. The two Hayden units operated by Xcel are to be shut down in 2027 and 2028.
The value of storage
A 2019 report by Synapse Energy Economics that was commissioned by the Colorado Energy Office spoke to the need for advanced energy storage as Colorado decarbonizes its electricity.
Storage can provide frequency regulation, voltage support, energy arbitrage and deferral of transmission and distribution infrastructure investment,” says the report, “The Future of Energy Storage in Colorado: Opportunities, Barriers, Analysis, and Policy Recommendations.”
“Although pumped hydro is currently the most prevalent type of energy storage in the United States, traditional battery storage technologies (primarily lithium-ion) have experienced rapid market growth within the last few years. As costs continue to decline in the coming decade, flow batteries are also expected to become common in large-scale storage applications.”
Pumped-storage hydro does not figure prominently in the analysis by Synapse. However, the consultant did find need for public policy that serves to encourage the market for storage in Colorado.
“Though lithium-ion battery costs are projected to decline in the coming years, there is debate about whether they are expected to become cost-competitive with traditional generators prior to the late 2020s without supportive policy mechanisms.”
In removing two coal-burning units at the Comanche station near Pueblo, Xcel Energy is adding 275 megawatts of battery energy storage. On a vastly different scale, United Power began using a 4-megawatt battery storage in late 2018.
In viewing the Craig project, Shapiro hopes to time completion to the closure of the coal plants. These projects require patience.
Shapiro already has already demonstrated great patience. In a life with many twists and turns since his upbringing in the New York City borough of Brooklyn, Shapiro by 1991 was on the Blackfeet Indian Reservation in Montana. In a paper titled E Pluribus Unum, Shapiro describes himself as a “creator, an entrepreneur, a public philosopher, a conscious citizen, a writer, and a father.”
In that paper, he says he was motivated to help the Blackfeet and, in that outlook, he began to wonder whether the steady winds of the Montana reservation could be harnessed to benefit the tribe. He quickly grasped the limits of renewable generation.
“Upon my return to New York, I immersed myself in the study of energy storage as a means of helping wind energy compete with conventional energy resources,” he explained. There were then 40 pumped-storage hydro projects in the United States among well more than 100 around the world.
Since then, in 1993, just one additional project pumped-storage hydro has been built in the United States. Many gas-fired plants were built, however, to address the need for peaking power.
Growing interest from utilities
About 2009, though, Shapiro noticed a shift.
“Renewable energy was surging, the interest in storage was starting to pick up, and more and more utilities were mentioning pump-storage in their resource plans,” he explained in a telephone interview. “So partners and I formed GridFlex to identify the best new sites in the country.”
His partners now include David Gillespie, who served a stint with Duke Energy as vice president of business development, and John Spilman, the general counsel, who has provided services to Vestas Americas, among others. Shapiro is the chief executive.
Utilities have shown much greater interest in the last two years after solar prices tumbled and, in response to consumers, many embraced 100% carbon-free goals. But the time was not lost. “We spent a lot of those years honing our knowledge about how to make the business case,” he said in a recent phone interview. “And we built relationships with equipment vendors and environmental consulting firms and others needed to move ideas into projects.”
Shapiro’s company, Gridflex, now in partnership with another company called rPlus Energies, a developer of utility-scale wind and solar, has filed with the FERC for seven sites: two in Nevada and one each in California, Colorado, New Mexico, Oregon, Washington and Wyoming.
Most, like the Craig site, are placeholders in the FERC process. Two, in Wyoming and Nevada, have moved to a second step with FERC, the pre-application stage.
In Wyoming, Shapiro last summer outlined a plan to use Seminoe Reservoir in conjunction with a new reservoir on federal Bureau of Land Management property for a capacity of 700 megawatts, somewhat larger than the Craig-Hayden proposal. The Rawlins Times reported that officials in Carbon County declined to endorse the project but were OK with the application with FERC proceeding. Cost of that project has been estimated at $1.8 billion
In Nevada, progress came earlier with the White Pine project getting press attention in Ely in 2014. But it has moved little further along than the Colorado project.
In Arizona, other developers have several proposals for even larger pumped-storage hydro projects. One using water from Lake Powell proposes to use the transmission built for the Navajo Power plant now being demolished. It has a price tag of $3.6 billion.
About the Craig-Hayden site, Shapiro declined to identify whether his company has agreements with landowners and other specific elements of what will be needed. He said he has begun outreach to utilities.
Holy Cross Energy might be one such utility. Its service territory includes Vail and Aspen but also Rifle, which is within 100 miles of the pumped-storage hydro, connected by a major transmission line. In its resource plan posted in 2020, Holy Cross specifically mentioned pumped-storage hydro as one option for being able to attain its goal of 100% renewable generation by 2030.
Jonah Levine, who wrote a master’s thesis about pumped-storage hydro in 2007, now works in the realm of biomass for Louisville, Colo.-based Lignetics.
“The evolving story is not of wind vs. biomass or even traditional resources vs. renewables,” he says. “The real question is how do we deploy these things together in the most efficient and effective ways? I don’t see that story enough. What is the best utilization of the resources to our society?
