FreeKillB posted:Interesting piece on why nuclear is so drat expensive. Yeah it's basically three effects which all add up: 1. Increased safety requirements, Chernobyl and Fukushima both increased the regulatory burden across basically every nation on the planet 2. A lot of people are terrified of nuclear power, which adds upon factor 1) significantly 3. Nuclear construction has kept decreasing over the decades increasing marginal costs on everything involved through no longer having the advantage of economies of scale, something oil, coal, gas and renewable all benefit from

There's also just the dumb solution. Keep peddling waste from temporary to temporary spots for hundreds of years. A headache? Sure. A problem on the scale of fossil-fueled climate change? Pfffff. EDIT: There's already so much toxic waste of early industrialization stewed away everywhere in nature that it's legitimately difficult for me to get worked up about one of the most heavily regulated and scrutinized forms of waste on the planet.

CourtFundedPoster posted:Hey, so I've been skimming this thread for a while, and I think understand the trade-offs of all energy generation systems except one. Geothermal energy is great, for heat. As for electricity that's a very mixed bag and someone else will have to respond. If I take Sweden as an example. There's been a massive expansion in the last 20 years, basically wherever possible, of geothermal heating. The reason is that as long as electricity is cheap it is an extraordinarily effective way to heat a home. All you need is to front the initial investment and then you drill and pump. Downsides are an increased demand on the grid which can (and does) create problems downstream. But as for heating through electricity, I'm not even sure if there is a more effective alternative.

bad_fmr posted:You are probably mixing "real" geothermal energy, which uses the heat coming from the core of the earth with residential geothermal heat pump system. The heat pump system has shallow wells and gets its heat from the soil that is heated by sunlight, so it is technically solar heating system, which means that the temperature gradient is not that big. So it is only really usable for heating, not for creating electricity. But it is really efficient form of heating for sure. Just a bit expensive to install. The real geothermal power plants on the other hand have hunderds of degrees heat gradient can be and are used to create electricity. I feel that is a bit semantical, but yes that was my point by putting anything other than geothermal heating under iffy. I know for instance that Iceland has lots of "real" geothermal power, but I also know that style is not really applicable anywhere not sitting upon a dormant/active volcano.

His Divine Shadow posted:We need our power for our own phasing out our own fossil fuel production and transition. The last thing we need are increased electricity prices from further integration with the clusterfuck that is continental europe and it's power generation policies. We are really dependant on our access to cheap electricity, we don't use gas at all for instance. Is that really what is happening though...? Transfer costs are still a thing and wind power is at the point where it has to be exported south and east because it can and will push energy prices to 0€ during increasing periods of the year. Needless to say, this both makes increasing renewables more dicey (not what we want) and makes nuclear less profitable (also not what we want). If the energy can travel south, theoretically, it should both increase growth of renewables and exert cost pressure southwards on coal and gas. Am I missing something here? suck my woke dick posted:Rapidly decarbonising your grid through only renewables and without wrecking your environment might be barely possible in Norway/Sweden/Finland. Even then, Finland wants to keep nuclear in the mix and Sweden has shelved nuclear exit plans. With insane radiophobes, blind renewables and nothing else everywhere optimists and corrupt fossil fuel boosters running amok across the rest of the EU I'd definitely want to insulate my power grid of I were running a Scandinavian country. There's talk of nuclear power returning to the north with all the industrial expansion going on. Highly theoretical at this stage, but at the rate energy needs are expanding, hydro power is about to go from abundant to scarce in northern Sweden within the following decades.

I mean, I'm not really worried about central Europe pushing up energy prices because most of what we pay here for energy is monopoly-rent from waves of privatizations of our power grid. But that might be an uniquely Swedish experience.

CommieGIR posted:And hell, you've got Germany telling the EU Commission that "Natural Gas is Green Energy", its pretty blatant now days how bad this is. The clearest indication that natural gas isn't going anywhere is that through the last two decades cutting off the pipelines to Russia has never even been on table. Instead it's expansion.

Putting aside the nuclear question, a bigger problem is that society is just uninterested and unwilling to steer as many resources towards non-carbon energy as is actually required. Where are our mass engineering storage projects, where are our massive state renewable projects. More and more money is being funneled, but it's still nowhere near enough and above it's still mostly incentive money rather than any kind of war economy where the state directly intervenes in education, construction and investment. Market is dominant and markets say investment goes to gas. Hundreds of thousands of people every year across the US and EU are learning skills which are only usable in fossil fuel industries. It's so blatantly backward.

CommieGIR posted:Yeah for the most part Nuclear is getting some pretty high scores, largely because the plants last longer, emit less overall lifetime emissions, and tend to be incredibly cheap to operate once they are completed. That's before we get to energy density and safety being a higher concern therefore they tend to be safer overall. Yeah Nuclear cost prohibitive factor is financing which uh, is not a real cost.

Phanatic posted:Again, opportunity costs exist even in the utter absence of profit motive. Sure, but it's the opportunity cost of planners, nuclear engineers and boatloads of concrete. Money is not a real restrictive factor at all, read up on how government financing works. Capital cost is never the restrictive factor for government investments in the developed world. On the contrary, wind power has real limitations as even with production capacity skyrocketing every year there's still so much pent-up demand in the system that money doesn't help.

Nuclear energy's problem is and continues to be energy markets. Its inability to flexibly accommodate demand cycles means it loses out to most other forms of energy generation when it comes to generating the only thing that really matters in a market, creating profitable revenue. Hydro, gas and renewables all decrease the profitability of nuclear power, at lower financial risk. As long as you have energy markets rather than energy planning this will not change.

Dante80 posted:A question. It is my understanding that the rated capacity for nuclear power is negatively affected to a degree in the summer due to the rise of water temperature in adjacent rivers/lakes/sea. Significantly, though not as as significantly as the underinvestment and problems with corrosion adding on-top in France's case. https://www.reuters.com/business/energy/warming-rivers-threaten-frances-already-tight-power-supply-2022-07-15/

What I'm always curious about is how household storage will factor in long-term. With every single household with money to spare around here getting solar panels, batteries and electric cars at the same time more and more households are practically off-grid (bar winter ofc).
