Race to Cut Emissions Splits States 01/18 06:23
PROVIDENCE, R.I. (AP) -- As climate change pushes states in the U.S. to
dramatically cut their use of fossil fuels, many are coming to the conclusion
that solar, wind and other renewable power sources might not be enough to keep
the lights on.
Nuclear power is emerging as an answer to fill the gap as states transition
away from coal, oil and natural gas to reduce greenhouse gas emissions and
stave off the worst effects of a warming planet. The renewed interest in
nuclear comes as companies, including one started by Microsoft founder Bill
Gates, are developing smaller, cheaper reactors that could supplement the power
grid in communities across the U.S.
Nuclear power comes with its own set of potential problems, especially
radioactive waste that can remain dangerous for thousands of years. But
supporters say the risks can be minimized and that the energy source will be
essential to stabilize power supplies as the world tries to move away from
carbon dioxide-emitting fossil fuels.
Tennessee Valley Authority President and CEO Jeff Lyash puts it simply: You
can't significantly reduce carbon emissions without nuclear power.
"At this point in time, I don't see a path that gets us there without
preserving the existing fleet and building new nuclear," Lyash said. "And
that's after having maximized the amount of solar we can build in the system."
The TVA is a federally owned utility that provides electricity to seven
states as the nation's third largest electricity generator. It's adding about
10,000 megawatts of solar capacity by 2035 -- enough to power nearly 1 million
homes annually -- but also operates three nuclear plants and plans to test a
small reactor in Oak Ridge, Tennessee. By 2050, it hopes to hit its goal of
becoming net zero, which means the amount of greenhouse gases produced is no
more than the amount removed from the atmosphere.
An Associated Press survey of the energy policies in all 50 states and the
District of Columbia found that a strong majority-- about two-thirds-- say
nuclear, in one fashion or another, will help take the place of fossil fuels.
The momentum building behind nuclear power could lead to the first expansion of
nuclear reactor construction in the U.S. in more than three decades.
Roughly one-third of the states and the District of Columbia responded to
the AP's survey by saying they have no plans to incorporate nuclear power in
their green energy goals, instead leaning heavily on renewables. Energy
officials in those states said their goals are achievable because of advances
in energy storage using batteries, investments in the grid for high-voltage
interstate transmission, energy efficiency efforts to reduce demand and power
provided by hydroelectric dams.
The split over nuclear power in U.S. states mirrors a similar debate
unfolding in Europe, where countries including Germany are phasing out their
reactors while others, such as France, are sticking with the technology or
planning to build more plants.
The Biden administration, which has tried to take aggressive steps to reduce
greenhouse gases, views nuclear as necessary to help compensate for the decline
of carbon-based fuels in the nation's energy grid.
U.S. Energy Secretary Jennifer Granholm told the AP that the administration
wants to get to zero-carbon electricity, and "that means nuclear, that means
hydropower, that means geothermal, that means obviously wind on and offshore,
that means solar."
"We want it all," Granholm said during a visit in December to Providence,
Rhode Island, to promote an offshore wind project.
The $1 trillion infrastructure package championed by Biden and signed into
law last year will allocate about $2.5 billion for advanced reactor
demonstration projects. The Energy Department said studies by Princeton
University and the Decarb America Research Initiative show that nuclear is
necessary for a carbon-free future.
Granholm also touted new technologies involving hydrogen and capturing and
storing carbon dioxide before it is released into the atmosphere.
Nuclear reactors have operated reliably and carbon-free for many decades,
and the current climate change conversation brings the benefits of nuclear to
the forefront, said Maria Korsnick, president and chief executive officer of
the Nuclear Energy Institute, the industry's trade association.
"The scale of this electric grid that's across the United States, it needs
something that's always there, something that can help really be the backbone,
if you will, for this grid," she said. "That's why it's a partnership with wind
and solar and nuclear."
Nuclear technology still comes with significant risks that other low-carbon
energy sources don't, said Edwin Lyman, director of nuclear power safety at the
Union of Concerned Scientists. While the new, smaller reactors might cost less
than traditional reactors to build, they'll also produce more expensive
electricity, he said. He's also concerned the industry might cut corners on
safety and security to save money and compete in the market. The group does not
oppose the use of nuclear power, but wants to make sure it's safe.
"I'm not optimistic we'd see the kind of safety and security requirements in
place that would make me feel comfortable with the adoption or deployment of
these so-called small modular reactors around the country," Lyman said.
The U.S. also has no long-term plan for managing or disposing the hazardous
waste that can persist in the environment for hundreds of thousands of years,
and there's the danger of accidents or targeted attacks for both the waste and
the reactors, Lyman said. Nuclear disasters at Pennsylvania's Three Mile
Island, Chernobyl and more recently, Fukushima, Japan, in 2011 provide an
enduring warning about the dangers.
Nuclear power already provides about 20% of electricity in the U.S.,
accounting for about half the nation's carbon-free energy. Most of the 93
reactors operating in the country are east of the Mississippi River.
The Nuclear Regulatory Commission has approved just one of the new, small
modular reactor designs -- from a company called NuScale Power, in August 2020.
Three other companies have told the commission they're planning to apply for
their designs. All of these use water to cool the core.
The NRC is expecting about a half dozen designs to be submitted for advanced
reactors, which use something other than water to cool the core, such as gas,
liquid metal or molten salt. That includes a project by Gates' company,
TerraPower, in Wyoming, which has long depended on coal for power and jobs.
As utilities quit coal, Wyoming is tapping into wind and installed the
third-largest amount of wind power generating capacity of any state in 2020,
after Texas and Iowa. But Glen Murrell, executive director of the Wyoming
Energy Authority, said it's unrealistic to expect all the nation's energy to be
provided exclusively through wind and solar. Renewable energy should work in
tandem with other technologies such as nuclear and hydrogen, he said.
TerraPower plans to build its advanced reactor demonstration plant in
Kemmerer, a town of 2,700 in western Wyoming where a coal plant is closing. The
reactor uses Natrium technology, which is a sodium-cooled fast reactor paired
with an energy-storage system.
In another coal-dependent state, West Virginia, some lawmakers are trying to
repeal the state's moratorium on the construction of new nuclear facilities.
A second reactor design by TerraPower will be built at the Idaho National
Laboratory. The Molten Chloride Reactor Experiment will have a core that's as
small as a refrigerator and molten salt to cool it instead of water.
Among the other states that support nuclear power, Georgia maintains that
its nuclear reactor expansion will "provide Georgia with ample clean energy"
for 60 to 80 years. Georgia has the only nuclear project under construction in
the U.S. -- the expansion of Plant Vogtle from two of the traditional large
reactors to four. The total cost is now more than double the original
projection of $14 billion, and the project is years behind schedule.
New Hampshire said that without nuclear, the region's environmental goals
would be impossible to meet as affordably. And the Alaska Energy Authority has
been working since 2007 to plan for the use of small modular nuclear reactors,
possibly at remote mine sites and military bases first.
The Maryland Energy Administration said that while the goal of all renewable
energy is laudable and costs are declining, "for the foreseeable future we need
a variety of fuels," including nuclear and cleaner natural gas-powered systems
to ensure reliability and resiliency. Maryland has one nuclear plant, and the
energy administration is talking with manufacturers of small modular reactors.
Other officials, mostly in Democratic-led states, said they're moving beyond
nuclear power. Some said they never relied heavily on it to begin with and
don't see a need for it in the future.
They said the cost of new reactors compared to installing wind turbines or
solar panels, the safety concerns and the unresolved question of how to store
hazardous nuclear waste are deal-breakers. Some environmentalists also oppose
small modular reactors because of the safety concerns and hazardous waste
questions. The Sierra Club has described them as "high-risk, highcost and
In New York, which has some of the nation's most ambitious goals to combat
climate change, the future energy grid will be dominated by wind, solar and
hydropower, said New York State Energy Research and Development Authority
President and CEO Doreen Harris.
Harris said she sees a future beyond nuclear, dropping from nearly 30% of
the state's energy mix currently to around 5%, but the state will need
advanced, long-duration battery storage and perhaps cleaner-burning fuels such
Nevada is especially sensitive to nuclear energy because of the failed plan
to store the nation's commercial spent nuclear fuel at Yucca Mountain.
Officials there don't consider nuclear power a viable option. Instead, they see
potential for battery technology for energy storage and geothermal energy.
"Nevada understands better than most other states that nuclear technology
has significant lifecycle problems," David Bobzien, director of the Nevada
Governor's Office of Energy, said in a statement. "A focus on short-term gains
can't alleviate the long-term issues with nuclear energy."
California is slated to close its last remaining nuclear power plant, Diablo
Canyon, in 2025, as it turns to cheaper renewables to power its grid by 2045.
Officials think they can meet that goal if California sustains its expansion
of clean electricity generation at a "record-breaking rate for the next 25
years," building on average of 6 gigawatts of new solar, wind and battery
storage sources annually, according to state planning documents. California
also imports power produced in other states as part of a Western U.S. grid
Skeptics have questioned whether California's all-in renewable plan can work
in a state of nearly 40 million people.
Research from scientists at Stanford University and the Massachusetts
Institute of Technology concluded that delaying Diablo Canyon's retirement to
2035 would save California $2.6 billion in power system costs, reduce the
chances of brownouts and lower carbon emissions. When the research was
presented in November, former U.S. Energy Secretary Steven Chu said the nation
is not positioned in the near-term to go to 100% renewable energy.
"They'll be times when the wind doesn't blow and the sun doesn't shine," he
said. "And we will need some power that we can actually turn on and dispatch at
will. That leaves two choices: either fossil fuel or nuclear."
But the California Public Utilities Commission says it would likely take
"seismic upgrades" and changes to the cooling systems, which could cost more
than $1 billion, to continue operations at Diablo Canyon beyond 2025.
Commission spokesperson Terrie Prosper said 11,500 megawatts of new clean
energy resources will be online by 2026 to meet the state's long-term needs.
Jason Bordoff, co-founding dean of the Columbia Climate School, said that
while California's plans are "technically possible," he's skeptical because
it's challenging to build that much renewable capacity quickly. Bordoff said
there is "good reason" to think about extending the life of Diablo Canyon to
keep energy costs down and reduce emissions as quickly as possible.
"We have to incorporate nuclear energy in a way that acknowledges it's not
risk-free," he said. "But the risks of falling short of our climate goals
exceed the risks of including nuclear energy as part of the zero carbon energy
