Thanks for the correction.
Let me put it this way then: Everyone thinks they are above average in competence, but the average Joe has less competence than they think they have. People in the lowest quartile (highly incompetent) have the most highly inflated opinion of their competence, while people in the highest quartile (highly competent) have a slightly depressed opinion of their competence (unless they are Sheldon Cooper).

Perhaps if we were able to build nuclear plants, like we used to do and like France still does, ... But Germany and Japan have stopped doing ... wonder why? Perhaps it has to do with waste disposal and public safety issues. Do you know what the hazards of nuclear generation are? Do you know more than the scientists in Germany and Japan? We are talking Dunning Kruger effect on this thread afterall ...
... we wouldn't need to rely so much on foreign oil. Or we could put as much money into solar and wind power and eliminate the need for oil all together, growing hemp to make biofuel for portable energy. It's not rocket science, you can do it in your back yard: I have. I bet even a redneck can ... oh wait there are youtube videos of just this being done ... The technology is there, the costs are virtually equivalent now and getting better and better for renewable energy. My solar panels generate more electricity than I use and I haven't paid an electric bill since august 2015. What's silly is to pursue oil and kill the planet in the process.

You'll have to show me the numbers on that. Sorry, not on topic. Unless you can tie it to the Dunning-Kruger effect ... Perhaps by referencing another paper like (I was searching for a previous thread on this off-topic issue and found this):
Climate Change is Real Message 3 AGW Bombshell? A new paper shows statistical tests for global warming fails to find statistically significantly anthropogenic forcing AGW Bombshell? A new paper shows statistical tests for global warming fails to find statistically significant anthropogenic forcing – Watts Up With That? ... by three economists that clearly are not climatologists and have no clue about climate modeling, but that think they can pass expert critique on climate change because hey, they can do maths ... ... now that is a great example of DK effect, yes?

The politics of fear, Germany and Japan both faced huge public pressure after a second gen power station failed and a whole 600-1,000 people theoretically received lethal exposure and have or will die younger (about 20,000 died near immediately as a result of the actual natural disaster). It wasn't science that made the determination. Increasing your risk of radiation caused death from 0.75% to 1.25% is not good, but it's not so catastrophic that we should decide not to build Generation III plants - from a scientific point of view. That doesn't win votes, though. Gosh, fear of accidents like have happened over and over and over? Cherynoble, 5 mile island, Fukushima are the ones we remember, fear of long term effects on people and their children? Pardon me, but I think it is very reasonable to be wary of nuclear power because of its past failures. Especially when you have a better alternative. Germany and Japan are committing to solar and wind etc generation because (a) it is economical and (b) there is low hazard potential
Yes, negligible. (a) I don't read links that require me to turn off my ad-blocker -- it is there for a reason. I get enough garbage as it is. (b) so I can't see the basis for your numbers. However, that did not stop me from looking myself:
quote: One kilowatt-hour is 3.6 megajoules: so your "440 people die globally per trillion kWh" becomes 440 people per 3.6 trillion megajoules ...... 122 people per trillion (10^9) million (10^6) ... or 122 people per 10^15 ... which happens to be a quadrillion (US), so your number here appears to be off by a factor of 10 or so, making my sources number less than your numbers for nuclear. These deaths are also all solely in production and do not accumulate through the life of the panels, unlike fossil fuel and nuclear, and this means you need to look at the deaths over the lifetime of the panels and windmills, not just at the initial manufacture because those lifetime generations add to the kWh generated by the panels per death and would reduce the death-toll by another order of magnitude or more. For instance, my panels should last 30 to 50 years with a small decline in output over the years. I also expect global warming to increase cloud cover in coming years. Then there would be the cost to dispose of the panels at the end of their life, so we can likely double the death-toll and be conservative. Still ahead, imho. A similar lifetime analysis for nuclear generation and the billion year lifetime for the waste product would add to that number. Of course the industry could switch to nuclear chains that do not create isotopes with extremely long half-lives, like Thorium 232 quote: Thorium is found naturally because, while it has a long half-life, the decay product half-lives are 5.7 years or less, so the eventual end of decay occurs relatively fast and thus relatively safe to dispose of at an earlier date. I was a fan in the 70's (when living in Toronto).
CANDU reactors are capable of using thorium,[34][35] and Thorium Power Canada has, in 2013, planned and proposed developing thorium power projects for Chile and Indonesia.[36] Seems to me using the Thorium 232 decay chain would vastly reduce the health and safety risk of nuclear power.
Similar numbers have been derived by others. And probably equally prone to comparing apples and oranges. Did you check them? Curiously, I don't doubt that the oil and nuclear industries gather all kinds of information suited to Forbes (business) type reporting to promote nuclear business and oil business.
Are you under the impression you know more than you actually do? You tell me, I have followed nuclear generation for several decades and have not seen any significant change, while there has been massive growth and development in wind and solar. Growth and development that will continue to improve product production and safety.
Are you saying that scientists in Germany and Japan set energy policy, based on science rather than politicians based on votes? That sounds like you think you know more about German and Japanese politics than you actually do. My question was not regarding the politics. It is the scientist and design engineers duty to show risk at a politically acceptable level. This is true of any product or construction. The other parameter to evaluate is distribution (and the cost in health and death associated with that), as nuclear (and coal and natural gas) generating plants are highly concentrated installations generating massive voltage, while my installation peaks at 240 VAC and is distributed by a cable that runs from the roof to the basement. A distributed system with solar generation at or near the end user means much more freedom to access power anywhere you want. This is why solar installations are making huge headway in developing countries, places that just cannot be economically supplied by nuclear power.
Well there is a supply issue, right? There are lots more dead things that became fossil oil than living things that could become, with further processing, useable oil. I'm fine it - the UK has the top 3 largest biomass-electricity plants in the world. In fact Drax is the largest plant in Europe, and provides us with 5-10% of our power. Of course, we have to import all that biomass (it's wood, incidentally) from other countries - and if those other countries followed our lead, we might not be able to do that.... Look into hemp, which is what I mentioned. Quick google:Hemp Fuel Guide » Hemp Frontiers Uses existing technology. Hemp grows faster than trees to produce the same energy, which of course is another method of converting solar energy into a usable product.
Did you ever investigate what happened to all the silicon tetrachloride that was produced to make your solar panels? In 2015, it was probably recycled, but it may still have been dumped. Even if you try other materials you still end having to use things like cadmium. Still, it's difficult to get away from the dangers of hydrofluoric acid of which a LOT is used. It's possible to use other chemicals (which are themselves also toxic, but easier to handle) but business is business and low regulation nations are going to be able to sell their products cheaper. Not worse than your standard computer and battery production and disposal is it? There are known risks that can involve standard operation procedures, typical of industry.
It should be pointed out that it can take about 2 years of continuous operation to pay back the energy needed to make solar panels. So assuming you installed them January 1st 2015, you're still several weeks from having saved the planet from anything. Then there is amount of carbon pollution that occurs as a result of making them. Depending on where they were made you might not get a net carbon emission benefit until 2019. Which I consider basically irrelevant, because all the costs\risks are up front and cease to accumulate once the panels are installed, unlike fossil fuel or nuclear generation.
Then you might consider possible damage caused by wind, rain and snow on your home; If a toxic chemical plant is hit by a natural disaster, that's an ecological disaster. If a toxic chemical transport ship has a spillage, it's an ecological disaster. Like oil tankers and pipelines, they keep happening. But my panels, once installed, do not add to that risk nor experience it year after year.
This is all simplified, and it's certainly better than Coal and oil, but it's easy to think you know more than you do when the environmental costs are moved from the point of generation to point of manufacturing and maintenance. I had a solar spill yesterday ... it was sunny all day. Wind rain and snow affect my house whether the panels are there or not -- they don't have any increased effect due to energy generation. New technology developed every day takes care of your other concerns (new materials, simplified manufacturing), if it takes two years for payback that is a small drop in the bucket for the lifetime of the panels, something
So what about Nuclear Waste? It's incredibly compact and well contained, ... And dangerous for billions of years? But there was a much more invasive way of using nuclear waste in Iraq with depleted uranium ammo ... one with long term effects for society there. You need to include that with your death count and your waste fields for solar panel materials.
... as opposed to just about all other toxic waste from all other methods. If we want to argue something like 'we can recycle waste products in solar power' then we can say the same for nuclear power only the improvements within our technological grasp are orders of magnitude greater. Really? what's the waste product from my panels 5 years from now? 10 years? Does it have a half life?
Because of THE FEAR, nuclear waste is more heavily regulated and monitored than other waste. Unfortunately, that same fear means there is a lot of political stalemate over moving it around. And I say it is legitimate wariness because accidents have happened and accidents will happen. Curiously I regard this the same level of wariness as being around new toxic chemical plants and from industries like fracking and mining. Chemicals that can cause birth defects and poison people for years after it gets into the groundwater..
quote: Wow. Just WOW. (to quote Faith). I have cancer, and I would not wish that on one single person. That risk alone is reason enough for me to forego nuclear power.
Do you know more than most scientists? And I haven't said that either.
Is your competence high enough to assess the facts correctly, or is your confidence a function of relative ignorance? My competence is sufficient to recognize risks as listed and detailed by scientists, to understand them, and to decide when I don't want to take them, especially when there are alternatives without those risks. Thank you for including the Dunning Kruger effect in your post, that made it more interesting.
