Any Green New Deal<br />

Needs <strong>Nuclear</strong> Energy<br />

James Conca and Judith Wright<br />

United States congressional members rolled out their “Green New Deal” in 2019 that calls <strong>for</strong> a rapid<br />

shift to carbon-free energy. As laid out by Rep. Ocasio-Cortez (D-NY) and Senator Markey (D-MA), the Deal calls <strong>for</strong><br />

some drastic measures to cut carbon emissions across the economy, from electricity generation to transportation to<br />

agriculture to building efficiencies.<br />

But the roll-out hiccupped a bit on the<br />

role of nuclear energy.<br />

At first, the proposal called <strong>for</strong><br />

phasing out all nuclear plants and not<br />

building any new ones. They also<br />

released a fact sheet nixing the<br />

possibility of building new nuclear<br />

power plants. Then they backed off<br />

and referred to future energy sources<br />

as clean, renewable, and zero-emission,<br />

which allows nuclear back in.<br />

Every true expert on this subject<br />

knows we need all non-fossil fuel<br />

energy sources, including nuclear, in<br />

order to reduce our carbon emissions<br />

in time to reign in the worst effects of<br />

global warming (Figure 1). To not<br />

increase, or to eliminate, even one<br />

would be to fail, especially with<br />

respect to nuclear or hydro which<br />

have been the only sources to significantly<br />

compete with fossil fuels in<br />

global generation.<br />

Clearing Confusion<br />

on <strong>Nuclear</strong> Energy<br />

The Intergovernmental Panel on<br />

Climate Change, the <strong>International</strong><br />

Energy Agency, the UN Sustainable<br />

Solutions Network and the Global<br />

Commission on the Economy and<br />

Climate argue <strong>for</strong> a tripling of nuclear<br />

energy by mid-century, requiring over<br />

1,000 new reactors, or 10,000 SMRs,<br />

to help stabilize global anthropogenic<br />

carbon emissions at near-zero.<br />

Even more persuasive, four of<br />

the world’s top climate scientists,<br />

Dr. James Hansen, Dr. Tom Wigley,<br />

Dr. Ken Caldeira and Dr. Kerry<br />

Emanuel, have shown that renewables<br />

alone cannot meet the goal of<br />

decarbonizing the world economy.<br />

The four scientists outlined how<br />

only a combined strategy of employing<br />

all the major sustainable clean<br />

energy options, including renewables<br />

and nuclear, and efficiency and<br />

conser vation, can prevent the worst<br />

effects of climate change by the end of<br />

this century. Even the Union of<br />

Concerned Scientists recently said<br />

we need nuclear to address global<br />

warming.<br />

Although everyone has focused on<br />

the Green in the Green New Deal, it<br />

really is as much about the New Deal<br />

part – the social issues of economic<br />

equality, jobs and social nets – as in<br />

updating Roosevelt’s original New<br />

Deal that brought the United States<br />

out of the Great Depression. The Green<br />

New Deal aims to create jobs and boost<br />

the economy, rework our farming<br />

practices, and provide living wages,<br />

family leave, and health care <strong>for</strong> all.<br />

Arguably, you can’t achieve environmental<br />

harmony without addressing<br />

human suffering and poverty. This<br />

dynamic tension between human<br />

survival and environmental sustainability<br />

is what led to our species’<br />

explosion in energy use beginning<br />

with coal and it’s continued increase<br />

to at least 2050. Answering the<br />

question – Do you want to eradicate<br />

global poverty or save the planet? – is<br />

not an easy one, but there is only one<br />

answer - Both.<br />

But most discussions have focused<br />

on the Green part of the Deal. Ocasio-<br />

Cortez has stated that we should go<br />

carbon-neutral in 10 years. While that<br />

is not scientifically possible, it is the<br />

type of goal that needs to be set in<br />

order to make any difference at all in<br />

the time frame we do have – about 20<br />

years.<br />

Presently, America is 64 % fossil fuel<br />

in electricity generation, but 87 %<br />

fossil fuel if you add in transportation<br />

which is dominated by petroleum.<br />

After 14 years of carbon emission<br />

decline as we replaced coal plants with<br />

gas plants, our emissions began to rise<br />

again in 2018 because of increased<br />

gasoline and diesel use, as well as just<br />

increased economic output. The global<br />

pandemic has caused some oscillation,<br />

but emissions will begin increasing<br />

again when we recover from the pandemic<br />

and its economic aftermath.<br />

What would a plan of action<br />

<strong>for</strong> nuclear look like?<br />

The only energy plan <strong>for</strong> generation<br />

that has any hope of achieving any of<br />

the goals we need, in the time frame<br />

| Fig. 1.<br />

Life-cycle emissions <strong>for</strong> each energy source. To achieve any type of green<br />

new deal, all four of the energy on the right must be replaced by a<br />

combination of all sources on the left, not a cherry-picked few. IPCC/EN<br />

we need them, is some <strong>for</strong>m of the<br />

following:<br />

p stop building any new fossil fuel<br />

plants.<br />

p stop closing existing nuclear power<br />

plants that have been relicensed as<br />

safe by the NRC, which is almost all<br />

remaining reactors in the United<br />

States. Crying that a penny or a<br />

euro a kWh is just too much <strong>for</strong> the<br />

world to bear is insane under the<br />

urgent need and the huge cost to<br />

decarbonize. And every time we<br />

close nuclear, carbon emissions go<br />

up.<br />

p build as many wind turbines as<br />

possible and site them along<br />

Tornado Alley first, where they<br />

produce the most power per MW<br />

installed (Figure 2). Putting<br />

them most anywhere else is selfdefeating,<br />

costs more and wastes<br />

steel.<br />

p put rooftop solar on all new<br />

buildings, first in areas that average<br />

at least 200 sunny days per year,<br />

again to make the steel used go<br />

farther (Figure 3, Gagnon et al.,<br />

2016).<br />

p build new small modular reactors<br />

as fast as possible to load-follow, or<br />

buffer, the renewables, instead of<br />

building new natural gas plants.<br />

SMRs cannot melt down and all the<br />

other scary things have been fixed.<br />
