The easiest, legit power curve I use for early-ish game are magmatic engines:
- Mine for starter metals and coal
- Stirling or Clockwork powering Pulverizer for ore multiplier
- Mine more for iron, ferrous, and to find lava in overworld (Nether works as well)
- Re-locate to same chunk huge lava pool(s) are in
- Manual cactus farm for waterproof pipe
- Magmatic Engines on overworld lava
1 Lava bucket lasts for a while in a Magmatic Engine and they make good early-game power at 5 MJ/t. The key is to being flexible enough to re-locate to the same chunk that a huge lava pool is in. Otherwise, you're looking at either a chunk loader (not cheap for early game) or Nether lava plus Liquid Tesseracts (also not cheap).
- 1 or more Quarries (now you have enough power to actually power it/them)
- Managed Tree Farm for saplings and apples to eventually make into Ethanol (Biofuel)
- Wood from Tree Farm into Charcoal
- Railcraft Steam Power --> Industrial Steam Engines from charcoal and biofuel
- AE for inventory and crafting
- etc., etc.
1 Managed Tree Farm is enough for 2 or 3 36HP boilers, which is good for several hundred MJ/t, which is enough to propel you to "end game" whatever. In my experience, progression is limited more by renewable, automated power than anything else. After the 1st 64x64 quarry, raw materials are rarely an issue unless you're going for Solar Arrays, which eat copper like nothing else, even after the Force --> Integrated Circuit boost.
Next world, however, I'd like to be a "sun worshipper", limit my mining to a minimum, and use 0 quarries, turtles, or other automated earth-raping technologies. This means bees, bees, and more bees ! Slow, yes, but MC is about having fun and self challenges are always fun.
A really challenging start would be using Biomes of Plenty and NetherOres, going into the Nether with a "starter kit" of a few clockwork engines, pulverizer, EE3 stone, and staying in the Nether for good. A 1-way trip to Hell. Water would be a problem, though... Might have to setup a (water) pump plus liquid tesseract in the overworld first, though.
Also, I wonder if managed arboretums would work on Nether Biomes of Plenty trees.[DOUBLEPOST=1375824746][/DOUBLEPOST]
Get a vanilla sapling
Create a multifarm - smalles is ok
Make a peat-farm
Make a peat-engine
Power the mulitfarm with peat
Collect the saplings
Put saplings in fermenter
Start your bio-mass engine and collect the power.
Thats where i am right now.
Yes, very efficient, renewable, and can be completely automated without stuff blowing up, assuming you use a chunk loader. IMHO, managed tree multifarms are a bit OP for power generation. The saplings, apples, and wood are generated at a good clip and if you use all of them, you can power 2 or more 36HP boilers to produce ~300 MJ/t gross. Net power is less since the fermenters, stills, squeezers, furnaces, etc.,. all use power, but still well over 200 MJ/t net.
Getting that much power via Solar would be....ugh.
