Sweden had a major company try to make lithium batteries but it was not economical viable without major and continuously infusion of government subsidies. The company Northvolt is the largest bankruptcy in modern Swedish industrial history.
Consumer price of the energy. Doesn't include connection fees, but those are a minority of the cost. Includes special energy taxes. But not sales tax.
For a real example, I'm on flat rate and if I use 1000 kWh my monthly bill will be 211 CAD (effective rate 0.21 CAD / 0.13 EUR per kWh) including taxes, connection, delivery, everything, but without subsidy. The amount I pay after the subsidy is applied would be less at 165 CAD.
Consumer price for here in South of Sweden during October was for me €0.22 per kW/hh which include tax. On top of that I also had additional fixed connection fee and an fee based on peak consumption rate (combined those two were an extra €125 for that month). No subsidy.
The reason for the high kW/h is because limited wind/solar during that month and high gas prices which result in high market price at the power exchange. The given reason for the fixed fees is because of the need to expand transmissions and build out more reserve energy to handle the increase variability of the grid as a result of the increase use of renewables and the outcome of decommissioning a few nuclear reactors in the south of Sweden.
It applies to most private residential and small-scale business electric use. Rationale would be getting quite political, as you might imagine. But I suppose there are several justifications that are given.
One is to offset the cost to the consumer for phasing out fossil fuels. Coal has been shut down and wind and storage and new nuclear is being built. Politically it has been presented as a matter of fairness; poor people are least able to pay for increases or to retrofit. A kind of wealth redistribution. (Though when you remember large corporately-run farms are included in the subsidy it's maybe not the most progressive form of redistribution.)
In Quebec where they have a great surplus of hydroelectric they also partly subsidize residential electricity with the profits of the surplus sale to the United States. The energy is so cheap there than resistive heating is cheaper than natural gas for home heating. Avoiding dependence on oil and gas imported from either the US or western Canada, or rather trying to lessen that dependence, is a standing issue for both Quebec and Ontario.
The argument against deregulation of energy prices is that poor people won't be able to afford it. But if you create a program that subsidizes some reasonable amount of energy per person per month the price of electricity can go as high as it needs to. I don't know if that was rationale in Canada but it's one possible rationale why government might want to aubsiduze energy usage.
As long there is no need to use gas during periods of non-optimal weather, then solar and wind is great.
The lithium battery plant in northern Sweden went bankrupt so its difficult to say how to solve the storage solution by both being cheap and financial viable. New battery solutions are being made, but in the end it need to be cheap enough over the long term. The current use of gas for non-optimal weather means prices jump up by a factor of around 100x of what it is during good weather, and the average price in nordpool (the northen pan-European power exchange) is about 20x than what you get with good weather. That should illustrate how much variability there is in the energy price right now, and how much people are paying for that gas powered electricity in periods of non-optimal weather conditions.
A lot of fossil fuel subsidies goes directly to support the high variability power grid, and they more than doubled during 2022 when the gas prices went up. It is incredibly expensive, likely more than nuclear, to have a grid supported by renewables during optimal weather conditions and fossil fuels during non-optimal weather conditions. It also generate a lot of waste in term of pollution which has a bigger issue both short and long term than nuclear waste.
Nordpool prices are not true market prices, as much of the demand does not participate in the market. For example, many residential customers still have fixed-rate contracts, and some power companies sell the power they generate to their owners at cost price.
Medical advice was quite different between nations. Doctors and chief epidemiologists gave their advice, sometimes opposite advice to others, grounded in scientific beliefs that the individual held at the time. One of the biggest controversy and debates was the effectiveness of non-N95 surgical mask against airborne virus particles. Different studies gave different results, and depending on which culture, country and professional you asked you got different medical advice. It only got more muddled when it came to outdoor vs indoor.
That is just one example. It is well known in medical research that culture has a major impact on research findings and should not be overlooked. What is correct or incorrect is not obvious in a international context, and what help people in one place can be directly harmful in an other.
What is going to change, and after what event? United States use of torture has been well known, documented and made into multiple movies and TV for the last decades. Multiple different governments have not only shown zero interest to charge people over it, but they have also given the green light to continue it. No president nor any candidate has shown even the slightest interest, nor has there been any grassroots movement that gone out on the street to demand accountability.
The thing that replaces the old memos is not email, its meetings. It not uncommon for meetings with hundreds of participants that in the past would be a simple memo.
It would be amazing if LLMs could replace the role that meetings has in communication, but somehow I strongly doubt that will happens. It is a fun idea to have my AI talk with your AI so no one need to actually communicate, but the result is more likely to create barriers for communication than to help it.
Is 1 meter bad? In context it seems to be missing what kind of waves normally hit the coast line, and what kind tide differences exist, and what the current water level is when the wave hit.
What is a typical maximum wave height during hurricane seasons in north of japan?
Apparently 2 meters is : A 2 meters (6 ft 7 in) high tsunami hit Chiba Prefecture about 2+1⁄2 hours after the quake, causing heavy damage to cities such as Asahi. (Tohoku 2011) [1]
WRT comparison with hurricane waves, I assume they carry a lot less energy than tsunami's, because they are "superficial waves" - caused by the friction of the wind on the water - whereas a tsunami wave is caused by the movement of a huge mass of mater.
People vastly underestimate the danger of a moving body of water in general, but especially when that water is where it isn't normally. Even a relatively tame storm surge picks up sewage, dangerous chemicals, debris, and confused wild animals.
The way to solve that is to introduce a different form of service to the state along side with military service so that the choice in practice become the same.
Is there anything in the constitution that forbids the government from requiring citizens to perform some kind of service to the government?
> Nothing has been shown more effective at tearing down prejudices than actual exposure and confrontation.
The result has been fairly inconclusive. What happen is that people generally keep their views about in-groups and out-groups, but then add exception for the person they get exposed to. A good experience/friendship do not translate to a change in definitions for the in-group, nor does it change existing negative generalizations of the out-group.
What has shown to be effective is demonstration of shared values by the out-group, while at the same time avoiding display of different values. When people share the same values, and more importantly, do not display a difference in values, then the in-group can be expanded.
If I remember right, the book Behave by Robert Sapolsky goes through this.
Given the number of cctv cameras that operate in the UK, and their continued growth, I am surprised that the rail operator did not have access to a direct view of the bridge. I am also a bit surprised that there isn't technology to detect rail damage, especially the power lines that runs over the track.
Where I live it is not uncommon for rail to have detection for people walking on the rail, and bridges to have extra protection against jumpers. I wouldn't be that surprised if the same system can be used to verify damage.
> Given the number of cctv cameras that operate in the UK, and their continued growth,
CCTV cameras are mostly in private ownership, those in public ownership are owned by a mass of radically different bodies who will not share access without a minimum of police involvement. Oh and of course - we rarely point the cameras at the bridges (we have so many bridges).
> Where I live it is not uncommon for rail to have detection for people walking on the rail, and bridges to have extra protection against jumpers. I wouldn't be that surprised if the same system can be used to verify damage.
This bridge just carries trains. There is no path for walking on it. Additionally jumping would be very unusual on this kind of bridge; the big suspension bridges attract that behaviour.
You mentioned twice that you are surprised by things which are quite common in the UK. I don't know where you're from, but it's worth noting that the UK has long been used as a bogeyman by American media, and this has intensified recently. You should come and visit, the pound is not so strong at the moment so you'll get a great deal to see our country.
The saying/claims in the last 20 years or so is that London has the highest ratio of cameras to people in the world, through looking at what seems more correct statistics it is only the 12th most dense camera city in the world. how well that translate to the rest of the country is much less talked about.
Here in Sweden, people walking on the rails without permission is a fairly common problem, which cause almost 4k hours of accumulated delays per year. For people who often travel by train, the announcement of reduced speed because of the system has detected people on the tracks are one of the more common ones, only second to the catch-all announcement of "signal error", which simply mean the computer says stop for a reason that the driver don't know or don't want to say.
When it comes to suicide prevention on bridges, it is not just the big bridges. Suicide by train is a fairly talked methods in the news as a work hazard for train drivers, and the protection here is for small bridges that goes above the track. Similar issues exist with bridges over roads and highways. Those methods are to my read of the statistics more common than the movie version of a person jumping from a suspension bridge.
People on tracks and suicide by train are, I suspect, way more common in London for us than elsewhere. I can't get solid figures though. But it seems to sit around 15k hrs of delays nationwide for people on tracks.
We had a big government inquest into suicide in 2018 which included asking national rail to justify it position and actions. Of the 30k rail bridges in the UK only the hotspots have any modern measures of suicide prevention; and the hotspots are mostly but not exclusively suspension bridges.
However, from your comment, I see that you might be meaning pedestrian bridges across tracks, which almost always have metal rails higher than an adult man here. Our older stone road bridges (which are very common) have thick and tall walls on the edge which serve a similar function if not as effectively.
However, I think to hark back to the original image and post - the bridge depicted is a train bridge going over a road. More like a viaduct tbh. Its highly unlikely that there is any normalised pedestrian access so it won't tank highly for assigning prevention and detection measures for either suicid, and its easily assessed from the busy public road so I doubt it makes the priority list for automated collapse detection.
There is technology that could detect rail breaks, in the form of track circuits: feed a current into a rail, detect whether it gets to the other end (or bridge the two rails at the other end of the circuit and see if it gets back to the start of the other rail). A variation of this is commonly used in signalling systems to verify that the track is clear: if a pair of wheels is in the track section then the signal will short across the rails and make the circuit show 'occupied'.
Ultimately, though, this kind of stuff is expensive (semi-bespoke safety-critical equipment every few miles across an enormous network) and doesn't reduce all risks. Landslides don't necessarily break rails (but can cause derailments), embankments and bridges can get washed out but the track remains hanging, and lots of other failure modes.
There are definitely also systems to confirm that the power lines aren't down, but unfortunately the wires can stay up and the track be damaged or vice versa, so proving one doesn't prove the other. CCTV is probably a better bet, but that's still a truly enormous number of cameras, plus running power supplies all along the railway and ensuring a data link, plus monitoring.
I mean, you're supposed to call the police or Network Rail: there are placards on the (remains of the) bridge with the telephone number. But yes, it's not uncommon to have to send a train to examine the line (at slow speed, able to stop within line-of-sight) after extreme weather.
One of the more interesting ways of detecting rail damage, and subsidence in general, is optically detecting noise / distortion in fiber optic cables. An applied case of observables which are the basis for an evaluative (the "signal") being utilized originally to diagnose possible maintenance issues and then going "hey there, wait a sec, there's a different evaluative we can produce from this exhaust and sell".
