I have to agree with Skeeter, the first IC we had, I had finally hit my 128 solar array mark, and that wasn't through the passive use of the matter generator I was feeding (I used maybe 20 matter to fill a couple of holes, out of 20+ stacks I had built up). I won't talk about the amount of wheat I had (although I did work for my 9001 wheat for that reason) as that is something I can easily replace when I need it, which in 1.8 isn't as often.
Okay, let me try it a different way, I'm already losing my own train of thought. The below is a list of the machines I had, in use, on the first Chaos Cluster server:
128 solar panels. In IC, that's 1280 Refined Iron Ingots (half that for unmacerated ore), 384 redstone, 384 coal (charcoal does not work), 384 glass, 608 copper ingots (half that for unmacerated ores), 394 tin ingots (half that for unmacerated ores), and 1216 wood (logs, not planks) (converted to rubber in an extractor). The cables to wire it all together, probably another 100 or so cables and 20 switch cables (60 redstone + 20 cables), but that pales in comparison to what it took to acquire the panels.
2 MFSUs. In IC, that's 16 diamonds, 72 coal (charcoal does not work), 28 iron ingots, 18 tin ingots, 18 copper ingots, and 128 redstone.
2 MFE's. In IC, that's 4 redstone, 12 cables, 12 tin ingots, and 8 iron ingotes.
2 Matter Generators. In IC, that's 54 wood, 18 lapis lazuli, 10 glowstone dust, 28 redstone, 64 iron ingots, 30 tin ingots, 45 copper ingots, 72 coal, 12 stone, 6 dirt.
Miner (with 64 diamond tipped pipe). In IC, that's 8 cobblestone, 8 redstone, 6 tin ingots, 74 iron, 9 copper ingots, 18 wood, 16 diamonds, 2 gold dust, and 1 glowstone dust.
Then of course there's the other smaller things: 2 macerators, compressor, extractor, recycler, crystal charger, and electric furnace. No, I didn't have a tesla coil, I was going to end up killing myself with it if I ever hooked one up. For anyone who's made traps and died to them, you know what I'm talking about. (total of 73 iron, 20 redstone, 3 glowstone, some stone, 6 tin, 21 copper, and 48 wood among the misc machines in this paragraph)
Now, that was just the machinery set up and running, in regular use (with the exception of the matter and the recycler, everything got used during a mining trip). Now lets go into tools, shall we? In order to power the Miner out in the middle of nowhere, I had to ferry power by paw using energy crystals, made 13 of them because of the extremely long boat ride (600+blocks). Add 13 diamonds and 104 redstone to our shopping list.
ODE Device for prospecting: 9 cables, 2 redstone, 2 gold dust, 1 glowstone dust, 1 iron ingot.
The signs were being left behind, all 50 of them, where I marked just how well depleted areas were, so nothing added there.
Also used a pair of MFE's to get the power from the crystals to the Miner. Add 12 tin, 8 iron, 12 cables, and 4 redstone to the list.
EC Manipulator (used to regulate power output of the MFE's here as much as back under the solar array): 9 redstone, 2 glowstone dust, 10 cables, 2 iron, 9 lapis lazuli.
Tools for mining by paw instead of sitting on a Miner watching SciFi shows on Netflix:
Diamond Drill and Chainsaw: 12 iron, 6 tin, 16 cables, 6 redstone, 3 diamonds.
2 BatPacks (better than a ton of batteries): 12 redstone, 28 cables, 38 tin.
10 RE Batteries (Additional power for use with the Mobile Charger, or just power carry): 10 redstone, 20 cables, 30 tin.
Mobile Charger: 10 cables, 2 redstone, 1 iron.
Total shopping list thus far:
Redstone 781
Iron 1551
Tin 552
Copper 797
Wood 1438
Lapis Lazuli 27
Glowstone 17
Diamonds 48
Gold 4
Coal 528
Glass 384
(all cable needs converted to copper/wood(rubber) needs, slight variance may occur in precise calculation)
So, not exactly a light list, is it. the glass and glowstone are the easiest things on the list, one just needs furnace time while the other is a quick trip in the Nether to mine only a few blocks of Glowstone. I'd also like to point out this was only the list of things in active use, not the stuff I had stockpiled or was trying to use but didn't have enough iron to use, since iron was the thing I was always out of.
The above is my arguement to "You should just start anew with the world", and it's only the beginning. I have two more things to add on to this: my chest contents (rough, rounded down), and the machines and chest contents on the last IC world we were in just prior to 1.8.

EDIT 1: Partial recovery from original chaos cluster server: sadly the latest I was able to get, at this time, was 6-2-2011, just prior to the installation of IndustrailCraft. I can however make certain claims about my stuff based on what's in the chests at that time: diamond pick (worthless in the industrial age but not in our pre-industrial 1.8 world), a few buckets, 1.5 stacks of gunpowder, 3 stacks of bones (personally harvested at a spawner, no traps or devices, just me, my sword, and lots of skeletons.), 1 stack of feathers, 1 stack of string, 1 stack of leather, 6 stacks of coal (I did the arithmetic using the amount of resources I claimed to have used in the first portion of this post vs the vast amount of coal in this chest (14 stacks + 11 pieces)), 2 stacks lapis lazuli (2 stacks + 12 present), 1 stack of wool, a single slimeball?, 56 raw pork, 44 porkchops, 27 raw fish (tell me that was an easy and fast gain). I can't get any more info from this file.
----------------------------------------------------------------------------------------------------------
EDIT 2: Okay, I got into my latest stash from just before the 1.8 update. 6 stacks of tin ingots, 5 stacks copper ingots, 4.5 stacks copper dust, 5 stacks tin dust, 9.5 stacks coal dust, 2.5 stacks rubber, half stack each of glowstone dust and gold dust, 2 stacks flint, 2.5 stacks redstone, 3.25 stacks copper ore, 1.75 stacks tin ore, 2 batpacks, 13 iron ore, 1 stack bones, 1.25 stacks uranium, 4 stacks cables, 38 solar panels, 6 MFE's, 1 MFSU, 1 generator, 1 iron furnace, 1 matter generator.
----------------------------------------------------------------------------------------------------------
The point I am attempting to make with these lists is the amount of resource gathering effort I've gone to and the amount of building I've done, the time spent at machines monitoring them keeping them powered feeding the resources through to be processed...I really don't want to have to go through the whole process of gathering and processing AGAIN with the same stuff I've gathered twice before. I'll put the things together myself and build myself, I just want the stuff to do it with and not have to hunt all over Notch's green half acre (past any explored areas once we finally get IC2 for 1.8, if 1.9 doesn't come first) just to find any of the resources needed to make Mr Coffee, let alone a solar array, a nuclear reactor with all the bells and whistles, an up to date MFSU (resource hungry doesn't begin to cover MFSU or Nuclear Reactor in IC2).
