It's total generated energy. Here is a cool chart in English https://www.energy-charts.de/energy_pie.htm?year=2019 It's "net generation"(whatever that means) so the numbers are slightly different.

Tab8715 posted:A quick Wikipedia search shows that China barely has any Nuclear Power but I’m still completely lost if they are intended to use it has a base load. A few article sort of allude to it but the complexity behind such a plan is extreme. To clarify, China is using nuclear power for base load right now, what you're lost on is how much of their base load is planned to be nuclear in the future silence_kit posted:Yeah, I'm confused too. Earlier in this thread, it was commonly posted that China is more committed to nuclear power than the US. And that the US is ignorant & backwards when compared to China & other Asian countries for not learning to love the atom. Comparing "% of total capacity, today" doesn't really make much sense when determining a nation's relative commitment to nuclear power. Put one rover on the moon with a MMRTG generator in it and suddenly the moon is "the most committed to nuclear power" lol To put the numbers in simpler terms, today China has almost as much nuclear power capacity as the United States does, but they plan to produce a lot more than we plan to produce. While we're in the process of building 2 reactors, they're building 11. While we are in the planning stage to build 10 more, they have plans to build 50. To create a car analogy, we're just a little down the street from them, but they're driving at 40 mph while we're trying to pull out of a parking spot. And you're asking "well aren't we really more committed to going fast?"

Jesus Christ guys, Rolling Stone is not for serious journalists, I don't even need to read it to tell you it's full of poo poo. The author is known for hit pieces on oil and gas that are just wrong on the facts, so it''s not worth the time to debunk. Anything specific you have questions about, post them here and if I know I'll respond. Re: what went wrong here, I don't know why there was a blowout, but you don't need more regulation to solve them as there are already severe financial incentives to avoid them. In California, you have a blowout prevention and control plan, weekly drills, and our regulatory agency (now called CALGEM as of 2020, but everyone still calls them DOGGR) can witness these drills. It's still too early to see what people in the know think of the data from the satellite, as they extrapolated the entire leak from one day's worth of data, but the EDF has been working with the oil and gas industry on the satellite and other methane monitoring methods. I'm not an reservoir engineer, but I work with them for my job and extrapolating how much oil and gas was in a formation based on limited data points is always part of the fight in litigation. I will say that at least this article doesn't use FLIR to attempt to show leaks, although I thought it did when I saw it weeks ago. Someone using FLIR to try and show leaks at a drilling or production site is almost always wrong and just making poo poo up, FYI. At least if the satellite's methods are proven we'll have real data we can use. CommieGIR posted:Yeah, 42% how often and how long, that almost sounds like they are padding their numbers... I'm with you on this one, only because I don't see them making such a drastic change in one year. Speaking of Germany and nukes, here's a working paper on how much Germany's phasing out of nuclear power has cost them, which attempts to take into account things such as health issues from burning coal, which are very real. An interesting quote from the paper: quote:Specifically, over 70% of the cost of the nuclear phase-out is due to the increased mortality risk from local air pollution exposure as a consequence of producing electricity by burning fossil fuels rather than utilizing nuclear sources

True, or Teen Vogue. I should have expanded more that you can find things debunking pretty much anything Justin Nobel publishes about oil and gas, so it's just not worth getting into it.

Think of any thing you know well that may not common knowledge among the typical New York Times crowd.

Now go read things written by the NYT and you'll find that yes, they're often not reliable too. I don't mean this as some dumb "fake news" I only watch Fox bullshit (I don't watch any news, but it certainly wouldn't be Fox), but you'll see the more technical it gets, the less your average journalist is able to understand it. The NYT article linked to is from 1990, if there was a big issue it seems it would have come up again in the past 30 years.

Rolling Stone definitely has an entirely serious and legitimate hard news unit led by Matt Taibbi and Michael Hastings. They focus on in-depth feature reporting, and have broken a lot of important stories. They're an award-winning news organization. Anyone who is doubting that should immediately rethink their media source diet.

Solar and wind power have huge fluctuations due to weather. When they make up almost half your power generation you get pretty wild fluctuations on a year to year basis. A better metric would be to look at yearly added capacity and these figures look very bad. 2018 was pathetic, 2019 and absolute disaster. Expansion has pretty much stopped due to NIMBYsm. There is zero interest from the Merkel government to change anything about it. Lots of early subsidized installation are going offline this year so we might start to see shrinking capacity soon.

this might not be the right place, but does anyone here work in commercial solar? if you were say a middle aged person with a bad back, and therefore not really capable of starting from the "bottom" (physical labor on roofs), how would you go about getting a foot in the door? I'm thinking anything along the lines of sales engineering, or installation project management. For instance, I read this post and think "this thing is going to sell like hot-cakes": https://runonsun.solar/~runons5/blogs/blog1.php/solworks/est/hands-on-ensemble-my-trip-to-enphase How can I help accelerate that as a day job? I'm of course completely unqualified, which is why i'm trying to figure out how and where to start. My operating assumption is that this industry is growing much faster than they can hire qualified people, so on-the-job training has to be "normal" to some degree, right?

I worked for Enphase when they were still a startup, and know multiple fellow graduates of my bachelors program that work there still. They're a good company in general. You have to have an engineering degree to get in on the high level stuff. If you lack that then you're going to end up in the admin side of things, and that's just luck, networking, and persistence. Project management for, and installation of said equipment is something that can be trained up, but you have to find a company willing to build you up. Some electrical experience will be required so maybe starting with some trade skills as an electrician and working on a pathway to becoming an installer of some kind. You'll want to take some basic electrical engineering courses as well if possible.

FYI: https://www.latimes.com/environment/story/2020-01-22/california-needs-clean-energy-after-sundown-geothermal-could-be-the-answer Three local energy providers have signed contracts this month for electricity from new geothermal power plants, one in Imperial County near the Salton Sea and the other in Mono County along the Eastern Sierra. The new plants will be the first geothermal facilities built in California in nearly a decade — potentially marking a long-awaited turning point for a technology that could play a critical role in the state’s transition to cleaner energy sources. ... The U.S. Geological Survey estimated in 2008 that California has nearly 15,000 megawatts of geothermal potential — nearly one-fifth of the total capacity of all power plants in the state today. That number could rise substantially if energy companies are able to develop new technologies that allow them to exploit deeper, lower-temperature geothermal reservoirs that currently aren’t economically feasible. ... What are the environmental impacts of this? How do the costs and time for construction compare to nuclear and natural gas?

Awesome installation costs, in line with large reciprocating HFO units on upfront capex with the obviously far lower ongoing costs. How often does an otherwise good well end up not being a goer based upon pollutants? Obvious one being SO2 but as with fracking, it is disturbing a wide variety of geological strata.

I'm being deployed for three weeks to decapitate and repower some old Clipper towers in Texas. While reading up on the (pretty drat cool and innovative) quad-generator direct-drive tech Clipper had, I discovered that South Dakota could have been 100% renewable and a net energy exporter ten years ago. Keep in mind that 17TWh of annual generation assumed 2.5MW turbines, and we're building 4.2MW on land these days. Repowering the shitbox old Mitsubishi towers down at Roscoe, for example, would bring it from 800MW to 3.6GW. That's a decent nuke plant or hydro dam, and you ain't buying a reactor for $1 Billion. Never forget: the only roadblock to a renewable grid is political will and the money handcuffing it. Rime fucked around with this message at 04:49 on Jan 29, 2020 |

If I had to take a guess based on South Dakota wind resource id's say 40%-ish capacity factor, and 25 year lifetime. Capacity factor is somewhat tricky in the wind industry tough, because you can put a huge rotor in front of a small generator and be doing a really high capacity factor but lovely LCOE.

I did my thesis on rock radioactivity. I used to collect samples of rocks, smash them up, and put them through a Gamma Ray spectrometer to measure radioactivity. I had some fun, rather radioactive, samples with high potassium counts. What you would expect for rhyolites. We also had access to core samples of the Bakken from North Dakota. My most radioactive, highest percentage of U, Th, and K samples did not hold a candle to how radioactive the Bakken core was. Additionally the use of FLIR cameras to identify leaks of light hydrocarbons is a solid technology so I dunno what the complaint is
