All energy problem reduce to problems of energy transportation. We have a huge fusion reactor in the sky. The challenge is capture and transit. The problem is not incidental; it's fundamental.

Have people considered battery trucks? I don't mean battery-powered trucks, but trucks full of batteries. It seems kind of silly when you can use hydrogen or natural gas in your trucks instead, but battery trucks may be the lowest-loss form of long-distance electricity transport.

Without thinking too hard about the efficiency, it's clearly just not a _safe_ proposition with our current best (most energy-dense per weight) batteries.

I've read somewhere that Czechs (day ahead price of 463EUR/MWh) produce electricity at 0.1EUR/MWh, then sell it to an exchange in Germany and buy it back for the "market" price. Somebody over there is getting extremely rich for no reason and I am wondering why nobody is doing anything about it...

> why nobody is doing anything about it > I've read somewhere Before wondering why someone, somewhere is not doing something, confirm that the thing is actually happening in the first place.

Don’t know about other countries but several people were arrested today in Croatia cos of similar business practices:)

Current spot price in northern Norway is €10.16/MWh, while it is €745.08/MWh in southern Norway (73x the price), largely due to limitations in transport networks between the electricity zones. The price in the northern zone is so low that some hydro plants have stopped producing electricity as they would be losing money at the current price level. https://www.skandiaenergi.no/dagens-spotpriser/ Electricity Maps has a…

Ive tried to explain this issue to EVs fanatics, but nobody listens. Anytime you mention energy transmision issues - you get total backlash. We wasted EU money on pointless stuff while we could have upgraded our transit cables etc.

The transmission issues will be solved: more and more HVDC interconnections start construction in Europe every year. Grids that still rely heavily on coal and natural gas can, and will, be improved.

An EV bought today will only get cleaner as the grid gets cleaner. A new fossil-fuel vehicle today will always be dependent on fossil fuels, and will always pollute at least as much as the day it was purchased.

Poland. As an EU citizen working online, it was as easy as buying a plane ticket, renting an AirBNB, registering a company, and waiting over a year until I got connected to the healthcare / social security system and such.

Wow that is really neat. Is there ever a problem with everyone wanting to move to all the good places haha? I wonder if they will get really expensive to live in like California and New York. Not that I’m saying CA and NY are the “good” places of USA but many perceive it that way.

Language barriers prevent that to a large degree. People mostly move for better jobs, often only temporarily (for a couple of years), and largely only if their current area is econmically depressed.

Sweden has four zones and according to [1] tomorrow's price will be from north to south: Zone 1: 14,25 cents/kWh Zone 2: 14,25 cents/kWh Zone 3: 108,64 cents/kWh Zone 4: 201,63 cents/kWh 1 Swedish krona is 0,094 USD. So between 1,3 and 20 American cents per kWh. Most people live in Zone 3 followed by Zone 4. Facebook's datacenter is in Zone 1. [1]: https://elen.nu

To put this into more human terms: a tesla model Y has a 75kwh battery.

So this means to charge it, at home, would cost between $0.75, $2.25, and $15.

A normal air conditioner uses about 3.5kw. So if it runs for 6 hours a day, so 21kwh/day. $0.21/day, $0.63/day, and $4.2/day.

Batteries are heavy. The heavier you are, the more power you need to move. This is why almost all battery based truck designs are very short range.

At the current electricity prices, break even point for household PV installations even in coldish climate (Latvia, Eastern Europe) is on the order of 3-4 years without subsidies. Granted, it does not solve the problem that the energy I'll spend in the fall/winter has to come from somewhere but financially it is at the very least closer to being balanced out. Also, this is in a country, where the net metering system…

Or, at night also? Solar is all fun and games until the sun goes down and your grid needs to not collapse.

Luckily most electricity use is during the day and wind blows also in the night and more in winter when there’s less sun.

Remember that, while prices have soared, electricity generation has not become more expensive. The "electricity crisis" is a crisis for European consumers but a massive windfall for producers. This is a market failure - not an electricity failure.

Can anybody explain why that is? Why a country that generates 99+% of its own electricity like UK is seeing price increases? Everybody blames the war, but AFAIK UK imports 1% of its gas from Russia, and its electricity is generated locally, so why are prices increasing? I would expect grain and wheat to increase 500%, not power.

It’s a self inflicted green transition with no back up plan or a plan

No matter what magic plan anyone comes up with it would take years to implement. Nuclear, more insulation, hydrogen, new gas fields. It's almost winter already.

More insulation is double edge sword. I moved into a super-energy-efficient house here in north/east Europe. Heating in winter is damn cheap. But retention works in summer too… so I had to get air conditioner :( And electrical ventilation is a must all year round to get air fresh, keep module at bay ant not loose energy living with open windows. Energy saving in bottom line will be abysmal :(

That house would be much worse without the insulation. That's why it's unbearably hot in summer in say a shack made of out sheet metal (such shack would be much more bearable if it was insulated).

That's just wrong. The components of electricity generation - the fuel - has exploded in price.

You may not be aware, but there's a war going on that is sort of impacting things on top of existing inflation.

I realize picking a scape goat feels easy but it's poor form and leads to not fixing the actual problem.
