100% Renewable energy by 2050? Europe's energy suppergrid

vil says...

This still does not wish away the problem of having to cover all wind and solar power sources with backups for windless nights.

North Africa is still the same time-zone. Consider connecting Australia.

Why Funerals are a Total Ripoff

newtboy says...

In case you weren't joking, I'll explain. That's 10pm on the East or West coast, 9pm 'central' time zone .
National stations often show programs at the same time (local time) on the coasts, but don't do a third or fourth showing in between for those in the middle of the country, who just get the East or West coast timing...meaning central time zone gets the same broadcasts as the East coast, all 1 hour earlier local time from the East coast time zone...so a program shown at 10pm in NY will be seen in Texas at 9pm Texas time, watching the same broadcast at the same exact time.

Real Time - Dr. Michael Mann on Climate Change

newtboy says...

No, my first paragraph attempts to spell out why solar PV is a dud for people who do it the worst way possible, by selling all the electricity produced at drastically reduced rates to the grid, then buying it back at exorbitant rates, you are wasting well over 75% of what you could be saving. Of course it looks bad when you waste that much.
I have no mechanism needed to make it financially viable, and the idea that it might take more energy to produce a panel than it will produce itself is ridiculous.
I didn't 'make time' for anything, it just so happened that my lifestyle was perfect for solar, since I already did my housework during the daytime.
I have what's called a 'time of use' meter, which means it splits the day into 3 time zones, and keeps track of what I produce vs what I use from the grid. That means I essentially do get 1:1 for my production, which never reaches the point where they owe me money, but does offset almost all the juice I use (during the daytime) At night, we use normal grid power at normal grid rates. Too bad Australia doesn't do it that way.

yes, there are costs to an array, but they are one time costs, and FAR less than what's saved. That part is simple math. My system cost around $34K after rebates, maybe $40 without them, and it saves me around $5K per year in electric costs (based on 2007 rates, which have gone up). That includes production costs, installation cost, shipping cost, permit cost, etc.
Here in the US, daytime IS peak power use time. it's when business are using the most power, and when AC units are on, so the grid uses the power I feed in without problem. Industry uses WAY more power than homes. Solar offsets them using the hydro, gas turbines, and ramping up nuclear plants during the day, when they are used the most.
If my bill is lower, it means I used less fossil fuel generated electricity, so it IS working like a charm. How do you think otherwise? it's not perfect, and doesn't erase all other production, and is not a solution to ALL energy production problems, but it is a good part of the solution, unless it's done in the least productive manner possible.

What are you talking about, 2-3X the energy input? If you actually only count the costs, not the profit made at each stage in selling/installing panels, they probably come in more like 5-10 times the energy input, with little or no carbon footprint (many factories make the panels using power produced by other panels...as in pure solar factories).
My calculations (verified by my bills) put it at <1/2 the cost of buying (mostly coal produced) electricity from the grid at 2007 prices (even without any rebates), so how do you figure coal power production is cheaper, even ignoring all the other costs/problems? Coal may give a 30 to 1 return if you ignore ALL the other costs involved in using coal. If you count them, it's more like 1 to 2, because the effects of coal are so incredibly expensive, as is the cost of digging it up, transporting it, storing it, burning it, and disposing/storing the toxic waste products.

The cost of restoring a river is far more than the value of 100% of the power generated by a dam during it's lifetime.

Put simply, if solar PV is such a bad deal, how are they saving me so much money even without any rebates?

And your first paragraph pretty much spells out why solar PV is a dud investment for small plant/home plant if it were completely unsupported by a plethora of mechanisms designed to make it viable financially (and that's before even considering whether the energy cost is significantly offset by the energy produced), not to mention trying to make time to do things when your PV production is high so that you're not wasting it.

I try to load shift as much as possible, even went so far as to have most of the array facing the west where we'll scrape out some extra power when we're actually going to use it (eg. in the afternoon, particularly for running air conditioners in summer), but without feed in tariffs that are 1:1 with energy purchase prices and government subsidies on the installation of the system, the sums (at least in Australia) just do not ever come close to making sense.

But as I said in the first paragraph, that is all financial dickering, it has nothing to do with actual energy used vs energy generated. There is no free energy, you have to spend energy to make energy. You have to buil a PV array, pay for the wages of the people who install it, transport costs etc etc. They all drain energy out of the system. And most people in places where feed in tariffs are either on parity with the cost of purchasing energy when your PV isn't producing align their solar arrays with the ideal direction for greatest generation of energy that they can get the best profit for, not for generation of energy when energy demands spike.

The consequences of this are that at midday, energy is coursing in to the grid and unless your electricity provider has some capacity for extended storage and load shifting (eg. pumped hydro, large scale battery arrays), it's underutilised. Come peak time in the afternoon when people get home, switch on cooling/heating, start cooking etc when PV's production is very low, the electricity company still has to cycle up gas turbines to provide the extra power to get over that peak demand, and solar does little to offset that.

So carbon still get's pissed away every day, but as long as PV owners get a cheaper bill, it's all seen to be working like a charm... ; )

The energy current efficiency panels return is only on an order of 2-3x the energy input, which is barely enough energy returned to support a subsistence agrarian lifestyle (forget education, art, industrialisation). There's a reason that far better utilisation of coal and oil via steam heralded the massive breakthrough of industrialisation, it's because coal has close to a 30 to 1 return on energy invested. Same with petrochemicals, incredibly high return on energy.

The biggest advances in human civilisation came with the ability to harness energy more effectively, or finding new energy sources which gave high amounts of energy in return for the effort of obtaining them and utilising them. Fire, water (eg. mills etc), carbon sources, nuclear and so on. Even if you manage to get 95% efficiency on the panels for 100% of their lifetime (currently incredibly unlikely), you're only turning that number in to 8-12x the energy invested compared to 25-30x for coal/petro, 50x+ for hydro and 75-100+x for gen IV nuke reactors.

Is there a time you are generally here, so we can finish our conversation? I am on the West Coast of America, to set the time zone difference if there is any.

I will be in and out all day. Give me a timeframe and I'll be sure to be near a computer about that time. If I can.

Why not? I almost did it, but ran out out of time with the first beta because I thought it was based on pacific time zone instead of eastern time zone. I only got to the character creation DOH! The game is HUGE!

Haha I just got my email for my beta key starting on Friday. I didn't do it like the past 3 times they asked me.

Oh hai, 3 winners so far in the cooking-channel contest, gonna stop right there and start baking, deadline in 2 days for further entries though, starting in Australian time zone!! send the recipes if ya gottem...

He said, jokingly-Yeah, riiiiight.

Fair enough Dag

...sucks now I can't deliver p-ponts to alla y'all that are either used to the stroke, or never expecting the surprise...My advice to all y'all lazy motherfuckers that just sit on yer power-points and never do anything with em?? Make someone happy today and worry about whether or not some dumb-ass bullshit belongs up on the front page just because you wanna pop-spit or promote your OWN videos (which I think is completely retarded, unless it's to promote some hella good shit, which most of you self-promoting motherfuckers's shit, ISN'T!?? DUH??)

Oh and Dag?? Fuck a buncha blaming the time zone or not copping to the real-deal timing IS after all, everythhing...I'm no fucking idiot. I KNOW there's a buncha whiny mother fucks, crawling up the sift's ass to burn me, all you poser fucks can fuck the fuck the fuck off and go back to sleep.

You know who you are....Suck my balls and gently carress the taint, rimjobs after I've had some schwarma and spanakopita and sag panneer, motherfuckers. You ACTUAL haters know exactly who and what you are and can't see yourself for the douche in your veins.

Ok. Got all that out. Back to shitting-on-bullshit when it screams, to the consternation of all haters everywhere.

Too bad for all those dead Kronospissant videos I can never fix to help alleviate the carbon-fucking-footprint that coal-burner left behind....because the arbitrary rules here suck donkey-dick!!

(It's no great mystery as to why this site was never able to make any fucking money...self-destructive, narcissistic circle-jerk of doom)

Comment hidden because you are ignoring dag. (show it anyway)

Sorry about the timing - you can blame time zones for that. I asked Lucky to make the change before I went to bed.

As many of you know from personal experience -- we're very unforgiving about dupes and undeads because it's a pain to sort out after the fact.

I didn't completely read your wall of text, Chingalera but this is something you're either going to accept - or not. I don't care to placate you. Or your persecution complex - stay within the community guidelines or be gone.

chingalera said:

Well thanks kinna dag. You pm'd me AFTER the fact and after I posted this to the sift-talk....THANKS, for the fucking heads-up.

If it's "sort of" a one time thing deal, Not fine. The only way anyone knows if the embed is not spot on is if another user (either the original submitter or someone else that sees and remembers it different, alerts someone.) WHY then, would not the person who cried foul contact the person who raised it from the dead and TELL THEM, rather than (and this is what i suspect) tattle to the admins (because they have a particular hate-stick lodged in their assess towards another user, or were never taught manners by their abusive mothers and fathers) who then unilaterally FUCKS MY POWERS AWAY) to the giggles and squeaks of the internet DOUCHEBAG who brought it to your attention? Which is what I KNOW has transpired, the cowardly little fucks whoever you are, suck it.

Cowardly. infantile, sophomoric douchebag bullshit thuggery.

Now, how do I get these powers back, and now codify these arbitrary "sort of" rules??

By bringing this mishap to the sift's attention, and perhaps *cough, put it to vote??

Voting only works for those who use it for evil apparently, just look at the state of the planet.

I would appreciate again, the ability to clean-up dead videos. I regularly fix dead embeds and then immediately give other videos a chance by *promoting them to the front page....to foster a spirit of courtesy and joy and good will in the hearts of the original submitter.....GOOD THING

I even deaded all of Kronosposidens dead shit since he's AWOL, and am bringing his back tto life slowly but surely, even though that charlatan gentle-man was the biggest prick in the universe to me, and set-out on a similar quest, to burn me at ever turn...

(like copper-dan the resident ban-hammer obsessive-compulsive) regularly peruses the sift for violators, to satisfy his badge-point quest to be head NARC of the site). GOOD THING?? I consider it not, but I suppose everyone needs their little jobs.

Can you...People who don;t recognize the hatred in your hearts, act as civilly as you accuse me of acting the opposite of?? Look in the fucking mirrors and stop lying to yourselves, it's getting really fucking old..

Or how bout this.

Let's take a fucking vvote, or pole (like the one in so many assess) and vote whether or not to let love rule...Just tell me to fucking leave and I will....Don't keep playing the the punk-ass bitch card about it why doncha??....Bare your true natures and use small words if you have to. please. A single sentence will do.

Sunday nights? That is when Family Guy and American Dad episodes are shown for my time zone!! Wait, does that mean no new episodes for 13 weeks?

The Problem With Time and Time Zones- Computerphile

Can't you (or shouldn't you) rely on the OS to handle this stuff? Seems a bad idea to put this functionality in your own program where it then has to be continuously maintained by you.

Ultimately, as the planet continues to get functionally smaller, we all need to shift to UTC and no DST. Everyone who doesn't live in GMT will just have to get used to sunrise at 11:00, lunch at 17:00, and sunset at 00:00 or whatever the local equivalents are.

My team at work has people in EST5EDT, GMT, AEST, and CST. My company also has people in IST, CET, MSK, CST6CDT, MST7MDT, PST8PDT, etc. And, of course, we have customers in every populated time zone on the planet. It's a constant pain in the ass to be doing these conversions.
