Week 5 (02.11 - 08.11) Nuclear Energy

Nuclear power plants are not a new idea, and unlike other renewable sources of electricity such as wind or hydroelectric powered plants, they have no extra requirements from the environment. Despite this most of power still comes from coal (39%) and gas (22%). Nuclear energy now accounts for only 11% of world electricity production and probably will be decreasing. [source]This video offers a brief introduction to the subject:

Currently, due to the Fukushima disaster, moods concerning nuclear energy are lower than ever.In Europe (mostly Germany) we experience gradual decrease of active power plants caused by protests of the environmentalists.

Germany under pressure of social-democratic Green government started to retreat from nuclear energy and it is promised that their last nuclear power plant will be closed before 2022. Due to hastiness of this project the demand for electricity has been mostly ensured by fossil fueled power plants (it's slowly being replaced by renewable power sources like solar panels or wind turbines).

Apart from violent accidents the most popular controversy is nuclear waste. It is hard to dispose, radioactive and almost eternal if not reprocessed. But is it the worst? Byproducts from coal fueled power stations can carry up to 100 times more radiation for the same amount of electricity produced. It is caused by uranium and thorium, both existing in trace amount in coal. But in the case of coal plants radiation emission is negligible - more relevant hazard is the emission of sulfur dioxide or nitrous dioxide, compounds responsible for acid rains and smog. ["coal ash is more radioactive than nuclear waste"]

If you enjoyed the first video, here you have videos presenting both sides of the coin.
Why we should use nuclear power plants

Or why we should not

One way or another, trying to build a nuclear power plant in Poland is hopeless [abandoned power plant construction in Poland] 

What is your opinion? Are times of nuclear energy gone forever? Do we have a better versatile alternative?

Comments

Nuclear power allows us to continue to power our lives without having to pollute the air. It also provides stable electricity which helps prevent the frequent power outages that many areas without nuclear energy face. So long as nuclear power plants are well regulated to maintain safety, there is no reason not to use it as a source of power.

However the leak in Japan killed many people. If there is a leak it can kill fish like in Japan. It costs a lot of money to build and take care of the plants. Still we can just use windmills, solar energy, Geothermal energy, Hydroelectric power, and bio-fuels.

This YT videos are great! It was a pleasure to watch them :) There are a lot of interesting information and they look so nice :))

According to the nuclear energy – I think that all these videos show that it has good and bad sides. I honestly have no idea which side is more reasonable. We all know that some people will respect the rules, and some will not, and in case of nuclear energy, and especially wastes, this is quite important. There always will be some accidents and we cannot prevent it. But on the other hand it is way more effective and economic to get energy from this source... Really hard to decide in my opinion.

You found great grafhic content to watch! Helena, I didnt know you are intrasted in power supplies! :)
The tragedy in Fukushima showed how dangerous consequence may be to damage the nuclear reactor . It is certainly something that we should think of when expanding this technology . But ! Future sources of supply , especially for Poland in perpective of next 50 years does not look rosy. Germany is much easier to complain about the problem of energy with about a dozen nuclear power plants. Regarding Poland its a pity that they allowed to lost money on an investment that will not be completed and the time and money devoted to this idea will be lost . It is unfortunately Polish technical thought . First build, then ask. I think that nuclear energy is a matter of time and sooner or later with no any alternatives left, at the large costs of coal mining We'll have to rethink this concept . again ...

I must repeat this, great videos! Really nice way to introduce the topic. In my opinion nucleare energy is the future and humanity should continue research in this area otherwise we drown in grabage from coal power. I think fear can't stop learning, because we never will develop. It's sad that Poland won't have nuclear power because we have a backward society with medieval-minded :) People are protesting and even not interested in exactly against what and they don't do some research.
Unknown said…
First of all, I agree with the predecessor, great videos :).

Looking at how the technology is evolving around us I'm shocked that since the 70's nothing serious has changed in the technology of nuclear power plants. Certainly to such a state of things contributed the crashes, which over the years sowed massive destruction. However, I believe that the development of this technology can give us more good than harm.
Kit said…
Well actually we can't.
We're not located in volcanic area, so we have only few tiny hot springs spots.
For wind turbines to work, you need strong constant winds, and we have those in some areas ( https://upload.wikimedia.org/wikipedia/commons/7/77/Strefyenergwiatru.gif )
And I'm not sure is biofuel ever become an efficient means for energy.

We can for sure use solar energy when we finally be rich enough ... or when solar arrays will be cheap enough.

Well long time ago, when I was in the high school a group of nuclear scientists came to my school. It was a private secret meeting only for the best students from school (we were playing Illuminati or something). They were talking about rebuilding the Żarnowiec Power Plant, and that was the first time I heard about nuclear plants in Poland. They were also reassured as, that by the time we'll become engineers there will be a few working nuclear plants in Poland. They were wrong.
Kit said…
They're so good, it was hard to add something new to the article and don't repeat what was said in the video :)
Kit said…
It's really nice that someone is openly for nuclear energy, when it's so easy to be against.
Probably the only time when protesters knew what they were really rioting about was during ACTA affair. But when riots are justified suddenly no one is listening.

Every energy producing technology has pros and cons. Personally, I think the nuclear energy the best for us these days. If I had a choice I would live nearby nuclear reactor rather than fossil fuel power station. It’s the “greenest” solution even taking to account by-products. It’s better to breath clean air and store pollutants underground. When it comes to solar and wind energy it’s still low efficient due to resources needed to produce and maintain the infrastructure.
Today I discussed that topic with my boyfriend and we agreed that nuclear energy can be compared to airplane flights. Lots of people are really afraid of planes - it's a relatively new invention, plus we hear a lot of stories about airplane crashes. However, when we think about the subject reasonably, we can see it's irrational, because the risk of an accident or death is much greater when you're traveling by car.

It's similar with nuclear energy. People are afraid of it because they've heard lots of stories about Chernobyl and Fukushima. However, they rarely realize how many people died because of air pollution, mining, and accidents in other types of power plants.

Personally, I'm strongly for the nuclear energy - it's really efficient and clean. I wish people knew more on that subject and cared enough to make some research.
I totally agree with Nina :)

Nuclear energy as everyting has its good and bad sides. A good thing is that its efficient way of obtaining energy, low air polution level. A minor cons is that the it might explode, contaminating large area for many, many years. It's also very expensive technology (cost of building nuclear power plant is very high, qualified staff must be employed). I think that until we wont find a way to obtain energy from more safe sources (wind, solar plants, hydroplants) we can use atomic power plants.
Unknown said…
I'm 100% yea for nuclear energy. It is the only way into the future for humanity. At least for next few hundred years, until we'll deplete our uranium and other nuclear reaction fuel. Hopefully until then we'll be able to make thermonuclear reaction, the so called fusion. Sea water is a fuel for fusion so then there will be no more place for energy or oil wars.
Unknown said…
In my opinion, the future belongs to renewable energy sources. We should develop in this direction and seek new and renewable energy solutions.
Now the most popular are wind power, hydropower and solar power plants. They are more efficient than they had been before. This is a good solution because it does not pollute the environment (pollution is a growing problem that we have to pay attention to). An important feature is also the fact that they are inexhaustible.
As for the nuclear energy it is a very efficient energy source but has a lot of disadvantages. It is dangerous and it has problems with toxic wastes. In the future, we should give up on building nuclear plants for renewable energy sources (to be more efficient). However, we cannot do it instantly, because it is very long and expensive process.
Michal Kulesza said…
I'm for nuclear energy, do you know that close to the Warsaw there is nuclear reactor of Polish Atom Agency? It's more for scientists and to produce isotopes used during anti cancer therapies.

People are aware of Nuclear Energy because of bad fame caused by Chernobyl and Fukushima. I believe that when we compare environmental degradation with energy plants fueled with coal, producing same amount of energy it will show us that nuclear energy is more friendly.

Biggest problem we have is with storing the waste from nuclear energy. One day I hope we will be able to safely send it to cosmos and place it in black hole to dematerialize it. (Maybe I should patent this idea, hey?)
Michal Kulesza said…
Oh, and there was some Polish ad 'Bezpieczny Atom' but sadly I can't find this movie anywhere :(
In my opinion it’s very important to build in Poland nuclear power stations. It’s more efficient than traditional coal and gas energy sources. Fossil fuels are depleted quickly causing CO emissions which have limits in Europe. It’s important to invest today in nuclear energy in order to have security tomorrow of this energy. In Poland coal is still the dominant source of energy from Silesia region but is very expensive to extract. Good example is "Kompana Węglowa” which has a financial problems.
Julia Osiak said…
The videos that you posted are great! They are such a fun way of informing people about important matters.
To answer your questions, I'm a bigger fan of nuclear energy than of coal power plants. I see both pros and cons to it, but if we want to think about more than just 50 or 100 years of our future, nuclear energy seems to be more reasonable.
Unknown said…

Of course I really love your videos. These are great and it was really pleasure to watch it. I still hear about this problem and I still have mixed feelings. Your videos doesn’t dispelled the doubts although their glory. I’m still in a deadlock in this topic.

Unknown said…
Reasons behind Germany's (and by that EU in generall) policeies on nuclear energy are as usuall in politics sad and cynical.
Germany is the biggest exporter of parts, machines and systems used in fossil fuels extraction and solar energy production. Nuclear power is objectively the most efficient and eco-friendly technology out there, but it's popularizetion would hurt German economy. Risks of nuclear plants breaking down, especially in europe, where there are little natural disasters that could put such facilities in danger are marginal with current technology while coal mining or even solar plants are far more costly, less efficient and require way more maintnance
Kit said…
My opinion on this subject is very smilliar. Although if you take in account how expensive or long-term investment it is, it may be to late for us to build nuclear power plant. Or we'll end up waiting for new miraculous technologies that will never arrive and burn away all coal.
Kit said…
This is quite accurate metaphor.
But at the end of the day, affairs and disasters draws more attention than actual research or proof of concept.

If people were choosing wether to buy a car focusing on tiny chance of inevitable death, the streets would be empty.
Kit said…
I visited this place 2 times. It's a tiny cyclotron reactor in the one room and some measuring equipment in the other. You can go there during "Night of the Museums".

Dumping it on any lifeless planet will bring the same efects :)
Kit said…
I did not know that.
So after all the negative fame of nuclear energy is carefully crafted to sell some other products? Just like christmas, birthday or valentine day is celebrated to sell some festive-themed merchandise? Damn you Illuminati.
Kit said…
These videos don't favor any particular choice, and I think it's important to let the audience decide what to think.
And being unsure is also a opinion. Only sith think in absolutes :)
Kit said…
You're probably right.
Even if it is not the best choice posible, nuclear power plants are better alternative to fosil fueled plants. Most of times in history 'better' was suficient enough to replace the older technologies/ways of doing things.
Kit said…
Every power plant is a very expensive investition, thats why there is not much private power distribution companies.
There is an article on Wikipedia about economics of nuclear power plants https://en.wikipedia.org/wiki/Economics_of_nuclear_power_plants
which says that nuclear power plants are the cheapers or the most expensive, depends on which side you're in.
Kit said…
What you're saying is no doubt true.
From purely ideological point of view no one would ever choose any fuel-based energy source, if one could just harness energy from thin air... well... burning stars.
But since now it is still the idea we stive for, not an actual plan.

And maybe the sun / wind / water power is inexhaustible, but the machines that harness this power are. And as most of us know, soemtimes excessively complicated production process of eco-friendly devices is more energy-consuming than all the energy it can save during it lifetime. (I'm reffering to some models of eco light bulbs right now)

Week 11 [03-09.06.2019] The problem with ecological cars emission in UK

The problem with ecological cars emission in UK Since the adoption of the European Emission Allowance Directive in the European Parliament, all car makers have tried to submit. Since 1992, the Euro I standard has been in force, which limited the emission of carbon monoxide to the atmosphere. The Euro VI standard currently applies, which limits the series of exhaust gases. These include: hydrocarbons, nitrogen and carbon oxides, and dust.   The most significant change was brought by the Euro IV standard. For the first time it introduced the limitation of nitrogen oxides, which are responsible for the harmful compounds of smog.   What is smog?   Smog consists of sulfur oxides, nitrogen and carbon. In addition, solid substances such as suspended dust (PM). Dust suspend in atmospheric aerosols may be in liquid and solid form. These can be particles of sea salt, clouds from the Sahara and artificial compounds made by people. These compounds often come fr

Week 12 (12.01-18.01.15) Are you an early bird or a night owl ?

Owls are nocturnal creatures. They’re wide awake at night and they sleep during the day. If this sounds like bliss to you, then, like about 20 percent of the population who find themselves most active at around 9 pm, you may fall into the same category as our feathered friend. Night owls often have difficulty waking up in the morning, and like to be up late at night.  Studies of animal behaviour indicate that being a night owl may actually be built into some people’s genes. This would explain why those late-to-bed, late-to-rise people find it so difficult to change their behaviour. The trouble for night owls is that they just have to be at places such as work and school far too early. This is when the alarm clock becomes the night owl’s most important survival tool. Experts say that one way for a night owl to beat their dependence on their alarm clocks is to sleep with the curtains open. The Theory is that if they do so, the morning sunlight will awaken them gently and naturally.
