Carbon-free energy refers to energy sources that do not emit carbon dioxide or other greenhouse gases during their operation. In the context of the video, nuclear power is highlighted as a carbon-free energy source that could help mitigate climate change. The script points out that nuclear power has been historically significant for its ability to generate electricity without contributing to greenhouse gas emissions, which is crucial for reducing the carbon footprint and slowing down global warming.

💡Nuclear power

Nuclear power is a method of generating electricity through nuclear reactions, typically in a nuclear reactor. The video discusses the decline of nuclear power despite its potential to provide a significant portion of the world's energy needs without carbon emissions. It also touches on the safety concerns and the economic challenges faced by the nuclear industry, which are key factors influencing its current status and future.

💡Climate change

Climate change refers to long-term shifts in temperatures and weather patterns, primarily caused by human activities that increase heat-trapping greenhouse gases in the atmosphere. The video script emphasizes the role of nuclear power in the broader context of combating climate change, suggesting that its carbon-free nature could be a valuable asset in reducing the global carbon footprint.

💡Fukushima disaster

The Fukushima disaster refers to the nuclear accident that occurred in 2011 at the Fukushima Daiichi Nuclear Power Plant in Japan, following a massive earthquake and tsunami. The video script mentions this event as a turning point that led to the shutdown or halt of construction on nuclear reactors in several countries, including Germany, China, and Italy, highlighting the impact of such incidents on public perception and policy regarding nuclear energy.

💡Renewables

Renewables are energy sources that can be replenished naturally and sustainably, such as wind, solar, and hydropower. The script contrasts nuclear power with renewable energy sources, noting that while renewables have become more cost-competitive and popular, nuclear power faces economic and public perception challenges. The video also suggests that the push for renewables has not been as strong for nuclear energy, despite its potential as a carbon-free source.

💡Decommissioning

Decommissioning refers to the process of safely shutting down and dismantling a nuclear power plant or other nuclear facilities. The video script discusses the trend of decommissioning nuclear plants, particularly in Germany, which plans to phase out nuclear power completely by a certain year. This process is significant as it represents a shift away from nuclear energy and raises questions about how the energy gap left by decommissioned plants will be filled.

💡Nuclear waste

Nuclear waste consists of radioactive materials produced as by-products of nuclear reactions, including spent fuel rods and other contaminated materials.

Transcripts

Thanks to the funders of Peril and Promise for supporting PBS Digital Studios.

Since the 1950s the world has had a carbon-free, weather-independent energy source.

It works with our existing grid and infrastructure, and it isn’t dependent on batteries or back-up

power from fossil fuels.

If the goal is to slow down climate change, shouldn’t we be building more nuclear?

But instead of installing this power generation everywhere we can, it’s on the decline around

the world.

What happened?

[OPEN]

Historically, nuclear power has been the world’s largest source of carbon-free energy.

Of course, nothing is completely carbon-free.

Fossil fuels were undoubtedly used to build every nuclear plant on Earth.

You need trucks to deliver the fuel rods, construction materials, and that kind of stuff,

but that trade-off applies to all carbon free energy, at least until we get those sweet

Tesla trucks.

Globally, nuclear generates 11% of power, and in the US it provides 20% of our energy.

But since 2013, six nuclear power plants in the US have closed, with dozens more looking

like they may retire in coming years.

After the reactor in Fukushima, Japan melted down in 2011, Germany, China, and Italy all

shut down or stopped construction on reactors.

People often cite safety as the big reason for shutting down nuclear power plants.

But when you actually look at the numbers nuclear is among the safest power technologies

we have.

But despite high profile accidents like Chernobyl or 3-mile-island, nuclear power generation

causes less illness and death than all other fuel-based energy production, by a lot.

Those deaths are just more spread out, they aren’t tied to one event, so we don’t

hear about them.

Most countries have continued decommissioning.

Germany plans to completely phase out nuclear by 2022, And when those plants go offline,

you’ve gotta make up for that lost power with something, and most of the time we replace

nuclear with natural gas or coal, not renewables.

The thing is, a lot of this is economics: even before the Fukushima disaster, nuclear

power looked like it was on its way out.

Nuclear is expensive and can’t keep up with cheap energy from natural gas.

But wind and solar started out expensive too, and only became cheaper after decades worth

of innovation and government policies.

So why isn’t there as big of a push behind nuclear?

For one thing, big environmental organizations are solidly anti-nuclear.

The Sierra Club for example, says they are “unequivocally opposed to nuclear energy”

- they point to disasters, risks of nuclear proliferation and the dangers of nuclear waste.

Nuclear energy is an area where a climate change solution is at odds with other things

people care about.

The Diablo Canyon nuclear reactor may have to close because they can’t afford to meet

new regulations designed to protect local fish populations.

And in particular, the impacts of nuclear energy have disproportionately fallen on indigenous

peoples around the world.

Since the discovery of Uranium ore in the southwest states, communities have been relocated

and hundreds of barrels of radioactive waste have ended up on Native American reservations.

Should our top priority be reducing carbon emissions or protecting people and biodiversity?

Like most climate change solutions, nuclear energy is full of difficult choices.

But besides nuclear we currently don’t have any carbon-free power generation that operates

on big scales.

The closest we can get is hydropower, which supplies 7% of the energy in the US, primarily

in the West.

But if you think nuclear is expensive and holds risks for ecosystems, just wait til

you hear about dams.

These days it’s easier to install smaller, more flexible renewables than big, expensive

power plants.

Some companies and researchers are trying to tackle a lot of these issues we’ve mentioned

here with cool futuristic technology like smaller reactors that are easier to build,

eliminate the possibility of a meltdown or reduce fuel waste – but most of these are

just concepts years away from deployment.

It's hard to even say if new designs will win over people that are currently afraid

of or worried about nuclear.

Or if they’ll manage to get through the strict regulations nuclear power has to contend

with in many countries.

And as long as fuels like natural gas are cheaper than nuclear, they’ll remain more

popular.

But if our goal is to stop climate change, using fossil fuels is not a solution.

Is it possible to keep global temperatures under control without nuclear?

Probably.

Is it a heck of lot harder?

Definitely.
