Masakazu Daibo returned to his hometown in Fukushima just last year to reopen a restaurant established by his grandfather

Masakazu Daibo has reopened his family’s eel restaurant in part of Japan declared a no-go zone after the 2011 nuclear disaster, but so far he has barely a single neighbour.

A decade after radiation forced tens of thousands to flee their homes in Fukushima, some towns in the region are still wrestling with the difficult question of how to rebuild a community from scratch.

After the disaster, 12 percent of Fukushima prefecture was off-limits and around 165,000 people fled their homes either under evacuation orders or voluntarily.

Numerous areas have since been declared safe after extensive decontamination, and incentives are being offered to lure people back. But many are reluctant.

Daibo returned just last year, reopening a restaurant established by his grandfather in the town of Namie, around nine kilometres (5.6 miles) from the .

Namie and 11 neighbouring communities were part of an exclusion zone around the plant, and for years Daibo could enter only on brief visits.

“There were no people but the town remained. It was really like a movie set,” the 65-year-old told AFP.

“I heard no human voices, and saw only wild dogs, cows, pigs.”

The radiation that blanketed the region forced him to discard everything in the restaurant.

Contaminated parts of the walls were removed and he lost everything inside, down to the sauce that had been kept cooking since his grandfather opened the business.

Daibo and his wife hesitated about moving back, but after restrictions were lifted in 2017, they decided they would try to revive the past.

“I want everyone to say ‘Oh, this is a long-forgotten flavour,'” when they taste his food, Daibo said.

“I hope that my presence will shine a light on this town.”

‘Survival is our big issue’

But few others have followed suit.

The restaurant is surrounded by empty lots overgrown with weeds. Wooden signboards are piled up next to a toppled bin in the porch of one abandoned building, in what was once downtown.

Restrictions have been lifted on just 20 percent of Namie, and the town’s population is seven percent its former size of 21,000, despite incentives including reduced rents and money for moving and renovation.

Around 36 percent of residents are aged 65 or above, higher than the 29 percent national average, and just 30 students attend local elementary and junior-high schools, compared with nearly 1,800 before.

Japan as a whole is battling low birthrates and an ageing population, but the issue is in stark relief in Namie.

“We feel like the future of 20 years from now has arrived suddenly,” said town official Takanori Matsumoto.

Namie hopes to raise its population to 8,000 by 2035, helped by national subsidies of up to two million yen ($18,500) per new family moving to disaster-hit areas.

“Survival as a community is our big issue,” Matsumoto said.

Just over two percent of Fukushima remains under evacuation orders, with the figure for evacuees officially at around 35,700, though some experts believe there could be nearly twice as many.

But there is no deadline for lifting all the evacuation orders, and doubts persist that Fukushima Daichii can be decommissioned on schedule by 2041 at the earliest.

‘I can’t go back’

For many, fears over lingering radiation and mistrust of the government’s decontamination process are major obstacles to returning.

“It’s not like I won’t go back. It’s more like I can’t go back,” said Megumi Okada, who was pregnant with her third child at the time of the disaster and left despite being outside the official evacuation zone.

“If I were alone, I would go home,” added the 38-year-old, now a mother of four living in Tokyo.

“But as a mother, I strongly feel that I want to avoid risks for my children.”

Around two-thirds of Fukushima evacuees don’t plan to return, according to a 2020 survey by researchers at Kwansei Gakuin University.

“Many people say they can’t trust the decommissioning target, and their distrust of government measures runs deep,” said Yoko Saito, an associate professor on disaster reduction who jointly conducted the survey.

For Megumi Okada and many others, fears over lingering radiation is a major obstacle to returning

The rate of return to reopened areas varies considerably.

In Kawauchi, which lifted its last evacuation order in 2016, the population is now 68 percent of its pre-2011 figure.

It’s a different story in Futaba, which jointly hosts the crippled plant.

A tiny portion of the town was declared open last year—but not a single person has returned.

All roads into the restricted zone are blocked by barricades, and those entering must wear plastic suits and cover their hair and shoes. Radiation levels on their bodies are measured when they leave.

Crumbling buildings, untended because of radiation, dot the region.

At a ruined inn, an antique clock sits stopped, and fallen teacups litter shelves in a nearby giftshop.

‘A little sad and lonely’

For many in reopened areas, returning has brought conflicting feelings.

Takao Kohata went back to Minamisoma after authorities lifted restrictions but is still haunted by radiation fears.

Government officials tout strict screening of food in the region, but “many people are still nervous,” the 83-year-old said.

The parents of his four grandchildren won’t let them visit, because they worry about radiation.

“I fully understand their concerns, but I feel a little sad and lonely,” he said.

Some evacuees say they feel forced to return as the government winds up support for the displaced.

“In the end, those who have no place to go and have low incomes are the ones left behind,” said Shohei Yamane, a psychiatric social worker supporting evacuees.

“This disaster will never end as long as there are needy evacuees seeking help,” he added.

Some who have returned have found it takes more than reconstruction to rebuild a community.

Yuko Hikichi helps organise gatherings and group exercise sessions to strengthen community ties in Namie.

“We are just at the starting line… Community-building is not an easy job. It is endless,” she said.

It’s a struggle Masaru Kumakawa knows all too well.

He returned to Namie three years ago, despite losing his wife there in the tsunami, and now lives alone in a new housing district.

The 83-year-old heads a community association, but has struggled to make contact with his neighbours.

“They lived in evacuation for too long,” he said at a newly built community centre.

“We ring doorbells but no one comes out.”

Hexbyte Glen Cove Big but affordable effort needed for America to reach net-zero emissions by 2050, study shows

The graph depicts annual U.S. spending on energy, as a percentage of GDP, historically and for each of the five net-zero scenarios going forward to 2050. The chart shows that annual energy-system costs for the net-zero trajectories are comparable to spending in recent history, but higher than for the reference scenario. The modeling assumed the same low oil and gas prices for the net-zero and reference scenarios. Because demand for oil and gas is higher in the reference case, it is plausible that oil and gas prices would also be higher. If that were the case, achieving a net-zero future may be less expensive than not pursuing decarbonization efforts. Credit: Princeton University

With a massive, nationwide effort the United States could reach net-zero emissions of greenhouse gases by 2050 using existing technology and at costs aligned with historical spending on energy, according to a study led by Princeton University researchers.

The new “Net-Zero America” research outlines five distinct technological pathways for the United States to decarbonize its entire economy. The research is the first study to quantify and map with this degree of specificity, the infrastructure that needs to be built and the investment required to run the country without emitting more greenhouse gases into the atmosphere than are removed from it each year. It’s also the first to pinpoint how jobs and health will be affected in each state at a highly granular level, sometimes down to the county.

The study’s five scenarios describe at a highly detailed, state-by-state level the scale and pace of technology and capital mobilization needed across the country, and highlight the implications for land use, incumbent industries, employment, and health. Initial results were released December 15, in recognition of the urgency to cut and the need for immediate federal, state, and local policy making efforts. Journal publications will follow in early 2021.

Over the last decade, there has been an outpouring of research from universities and pledges from cities, companies and states investigating and promulgating efforts to decarbonize energy and industrial systems. The task is to keep global temperature rise to well below 2 degrees Celsius to avoid the worst effects of climate change. The goal of a “net-zero emissions” economy means emitting into the atmosphere no more greenhouse gases than are permanently removed from it through technology-driven or enhanced natural processes. If successful, the strategy would stop the buildup of greenhouse gases in the atmosphere, which is essential to limiting global warming.

Past research has probed whether net-zero is technologically possible and what it might cost to get there. But a missing piece has been detail that could inform local officials and authorities responsible for making decisions about important areas for the transition, such as siting and , along with information for the communities and stakeholders that shape and are affected by these decisions.

“Most studies do not provide this high geographic resolution for every state in the country, making it hard to tangibly appreciate what it will take to get to net-zero. Our research helps make a net-zero future vivid and real for people,” said Eric Larson, a lead researcher of the study and a senior research engineer at the Andlinger Center for Energy and the Environment. “Unless we roll up our sleeves and really understand what we have to do by when, we won’t be able to meet our goals,” said Larson, who also leads the center’s Energy Systems Analysis Group.

The Princeton University study was led by faculty and researchers at the Andlinger Center for Energy and the Environment and the High Meadows Environmental Institute (HMEI). The project leads include Larson, Jesse Jenkins, assistant professor of mechanical and aerospace engineering and the Andlinger Center for Energy and the Environment, and Chris Greig, the Theodora D. & William H. Walton III Senior Research Scientist at the Andlinger Center. The research is an ongoing project of HMEI’s Carbon Mitigation Initiative, a research program focused on studying and addressing climate change, and is aligned with the Andlinger Center’s Rapid Switch, a broad research initiative investigating how to accelerate decarbonization efforts globally.

The new research, which involved ten Princeton researchers and eight external collaborators, lays out five pathways by which the United States could decarbonize the entire economy in the next 30 years.

John Holdren, former science advisor to President Obama and former director of the White House Office of Science and Technology Policy, called the study remarkable and said it called attention to the areas where policy measures are most needed.

“Everybody seriously interested in the crucial question of this country’s energy-climate future—not least the new Biden-Harris administration—needs to understand the findings of this extraordinary study,” said Holdren, who is a professor in Harvard’s Kennedy School of Government and Department of Earth and Planetary Sciences, and the John A. Paulson School of Engineering and Applied Science.

The chart summarizes key characteristics of each of the net-zero trajectories that the new research presents, compared against the reference case, a business-as-usual scenario with no concerted decarbonization effort. Each of the net-zero pathways provides a way to decarbonize the entire U.S. economy by midcentury, but uses a different mix of technologies to get there. Credit: Princeton University

Because all five scenarios take the country to net-zero emissions, the researchers are neutral as to which is the “best” or most likely to be implemented. All of the pathways were found to involve annual spending on energy within the historic range of what the country spends on energy each year, about 4-6% of gross domestic product, or GDP.

“Net-zero pathways require spending a similar fraction of GDP that we spend on energy today, but we have to immediately shift investments toward new clean infrastructure instead of existing systems,” said Jenkins.

According to the research, following a “business-as-usual” pathway without concerted decarbonization efforts, the country would spend about $9.4 trillion on energy over the next decade. In all five net-zero scenarios, energy system costs are estimated to be only about 3% (or $300 billion) more for the decade, and this percentage shrinks further if oil and gas prices are higher than modeled.

“We now have a good body of evidence that shows, ‘yes, it’s affordable.’ We can do it,” said Larson. “And, of course, there are significant costs of not doing anything. Climate science has shown that unchecked warming will harm communities here in America and all over the world from changes in disease pattern to the displacement of millions of people from sea level rise and flooding from more intense storms.”

The scenarios that the new research details include a “high electrification” or E+ scenario, which involves aggressively electrifying buildings and transportation, so that 100% of cars are electric by 2050. The “less high electrification” or E- scenario, electrifies at a slower rate and uses more liquid and gaseous fuels for longer. Another scenario, noted as E- B+, allows much more biomass to be used in the energy system, which, unlike the other four scenarios, would require converting some land currently used for food agriculture to grow energy crops. The E+ RE+ pathway is an “all-renewables” scenario and also is the most technologically restrictive. It assumes no new nuclear plants would be built, disallows below-ground storage of carbon dioxide, and eliminates all fossil fuel use by 2050. It relies instead on massive and rapid deployment of wind and solar and greater production of hydrogen to meet carbon goals. The E+ RE- scenario, by comparison, relies on “limited renewables,” constraining the annual construction of wind turbines and to be no faster than the fastest rates achieved by the country in the past, but removes other restrictions. This scenario depends more heavily on the expansion of power plants with carbon capture and nuclear power.

“Since getting to net-zero looks affordable, the next key question is if we are going to do this, how do we want to do it? Everyone will benefit from limiting climate change, but the different scenarios do have uneven effects as they play out. Who benefits more, and who pays more? Can we do it equitably, and so that enough people see clear benefits that there is an enduring coalition of support?” said Jenkins.

He said those questions are very different from the ones that energy and climate researchers typically address, which is why Net-Zero America research required a large team with diverse disciplinary backgrounds and skills to carry out the investigation. In all five scenarios, the researchers found major health and economic benefits across the country. On each pathway, by 2030 coal is no longer used for power generation, and there is an associated reduction in emissions of nitrogen-oxides, sulfur-oxides and fine particulate matter from power plants. Reducing exposure to fine particulate matter avoids 100,000 premature deaths, which is equivalent to nearly $1 trillion in air pollution benefits, by midcentury compared to a “business-as-usual” pathway.

The actions to achieve net-zero emissions create approximately 500,000 to 1 million new energy jobs across the country in the 2020s alone, with net job increases in nearly every state. The scenarios that more heavily rely on wind and solar see more energy jobs created. In nearly all states, job losses in extractive fossil industries are more than offset by an increase in construction and manufacturing in the clean energy sector. Significant job dislocations and transitions will occur in some states where the economy relies heavily on coal and oil, such as West Virginia and Louisiana. The researchers said the granular findings are useful in identifying where and when dislocation will occur and can inform public policy strategies to effectively manage these transitions.

“These findings can inform critical policies that can help manage the effects of the transition and create a more just clean energy economy and society,” said Erin Mayfield, a postdoctoral researcher at HMEI who led the employment and air pollution analysis in the study.

In all net-zero scenarios, the required scale of investments and the pace of building new infrastructure demand that rapid change starts immediately, the researchers said.

It shows where and how much renewable energy could be deployed at least cost, subject to siting restrictions assumed in the modeling, in order to meet net-zero goals.

“We have all the technologies we need to get started. We need to be deploying them much more rapidly than we are today, and we also need to be investing to create real options for those less mature technologies that will be needed for the longer term,” said Greig.

Wind and solar power, along with the electrification of buildings and cars, must grow rapidly this decade for the nation to be on a net-zero trajectory. The researchers said the 2020s must also be used to continue to develop technologies, such as those that capture carbon at natural gas or cement plants or those that split water to produce hydrogen, so that they are affordable to deploy at scale in the 2030s. But for the next several years, the researchers said most of the big investment revolves around clean electricity and electrification and is similar across all of the scenarios.

According to the research, the United States will need to expand its electricity transmission systems by 60% by 2030, and may need to triple it by 2050. Electrifying buildings, primarily by adding heat pumps for water and space heating, and electrifying transportation is another step that must be accelerated in the 2020s to set the stage for any of the pathways.

“The current power grid took 150 years to build. Now, to get to net-zero emissions by 2050, we have to build that amount of transmission again in the next 15 years and then build that much more again in the 15 years after that. It’s a huge amount of change,” said Jenkins.

A critical issue for driving this clean-energy agenda is where new solar panel and wind turbine manufacturing facilities are built, and where the solar and wind farms themselves are sited, along with biofuel production plants. The research provides city and regional maps that show where it is least costly to build these facilities and where they integrate into the energy system most efficiently. But this does not account for the social and human aspects of where to construct new infrastructure.

“Individuals and communities across the country are going be affected by net-zero transitions in different ways. All Americans will be crucial partners in this transition, and we must be sensitive to the needs and values of communities when planning and implementing the very significant infrastructure and other developments needed to get to net-zero,” said Greig.

The researchers said they hope that the report will, by providing a variety of futures, provide confidence that the United States has several genuine pathways for getting to net-zero emissions, and help guide investment and policy priorities over the next few years. They said the research offers insights on how to make decisions over the near term that are consistent with eliminating net-carbon emissions 30 years from now.

“None of the Princeton scenarios will prove to be ‘right,’ but together they provide a compelling picture of possible paths forward,” said Holdren.

“The motivation is to provide granular guidance for decisionmakers as to what it would take to make those net-zero pledges a reality, with a focus on the actions we need to take today that will have lasting impacts long after the CEO is retired or the policymaker is out of office,” said Jenkins.
