Because it’s what is being used in Montana, Wyoming, Indiana and some parts of Florida that I know of personally because I have seen TV ads and know people working with the advocacy groups on the local level.

I have friends who mention that it is also going in Georgia, Alabama, Tennessee and Kentucky.

That evidence enough.

Indeed. It’s nice that they are frank about this in the discussion but worrying that they say nothing about it in the abstract. A good journal wouldn’t publish this without an explicit warning that it was a post hoc analysis. Violation of basic CONSORT guidelines.

>Maybe some russian company can pump out reactors which then don't comply with EU or US safety regulations, so that doesn't help anyone..

Prior to war breaking out, Rosatom was building reactors for countries all over the world. This is public information. If you want a source, you can check wikipedia. Providing sources is more important for information that is niche, newer, or isn't readily available on google, none of which is true here.

But if you want a source that actually is news and makes sense to provide a source for, how about the SMR being build in Ontario. It's slated for completion in 2028, just five years from now.

>Also the cost of energy storage is included, so your whole point about energy not being available is wrong.

No, it isn't wrong. Your own source provided above, the wiki article, mentions this:

>Levelized avoided cost of electricity
>
>The metric levelized avoided cost of energy (LACE) addresses some of the shortcomings of LCOE by considering the economic value that the source provides to the grid. The economic value takes into account the dispatchability of a resource, as well as the existing energy mix in a region.

Which is literally what I just tried to explain to you. So you can ask for sources, but if you aren't even reading your own, is there any point? I'm really not trying to be a jerk here... that's an honest question. If someone was standing in front of you with a Harry Potter book in their hand and you said "Harry Potter has a lightning bolt scar" and someone said they didn't believe you and to prove it, how would you react?

Additionally, even if I did provide other sources, the degree to which they would be useful to this conversation depends on your familiarity with electrical engineering. I think a lot of people take electricity for granted because you stick a cable with metal prongs into the wall and stuff automagically starts happening. But the system behind all that is hugely complex. One challenge that isn't addressed at all by levelized cost studies is the reduction of inertia that is associated with replacing conventional generation sources with things connected through inverters like solar panels and wind turbines. Conventional generation sources don't have inverters and their inertial mass is coupled directly with the grid. That has a number of advantages that aren't accounted for at all in LCOE. I mean this with no disrespect, but if you don't understand the significance of what I just said, how is it that you think providing sources is going to help? Unless I can find a Veritasium video or something like that that takes the time to explain concepts like that in a way that is easily digestible, which I doubt exists, then no source I can provide will be helpful.

Does a review of existing research really qualify as new research? This looks like the equivalent of a grade school science student's book report.

We already know the mechanisms behind this. People who eat meat are heavier on whole, which increases bone mass. Vegans tend to be thinner, which decreases bone mass.

Stronger bones won't protect you against heart disease.

Likely part of larger problems with the population being deficient in D

FYI if you live in certain areas you probably need vitamin D. The line shifts depending on your skin tone. Try some even if you aren't pregnant, you might notice a difference in your mood and/or health

Obligatory IMNAD talk to your doctor
