Anno in-depth: Energy
By Glyphis
Everything there is to know about energy production. The following buildings will be discussed:

Eco faction:
- Wind park
- Thermal power station
- Offshore wind park
- Solar tower generator

Tycoon faction:
- Coal power station
- Nuclear power plant

Tech faction:
- Marine current power station
- Hydroelectric power plant
- Geothermal power plant (Deep Ocean DLC is required)
- Energy transmitter (Deep Ocean DLC is required)

Besides these induvidual sheets, I have also created some comparison tables to compare the different options considering the production of energy.

Notes
  • Keep in mind that accidents may occur when operating a Nuclear power plant: If there is an accident and your Nuclear power plant explodes, you are pretty screwed.
  • The Nuclear power plant requires fuel rods, which are made out of uranium. A closed circuit can be made using 1 Nuclear power plant : 1 Fuel element factory : 1 Uranium mine or by using 2 Nuclear power plants : 2 Fuel element factories : 1 Uranium metal converter.
  • Upgrades for a smaller change of accidents, lower maintenance costs or more energy production can be researched in your Academy.

(*)Energy output depends on the number of inhabitants within the influence area.
Comparison table including upstream production chains
Since some power production buildings need resources in order to work, I have also made a comparison table with these needed resources included in the total costs and output. All layouts are designed as a closed circuit when all buildings are running at 100%.

I love reducing the influence area of my wind parks to 0% so i can spam them for cheap up to lategame.
Abster 17 Jul, 2015 @ 4:59am 
Superb guide!
二猫 5 Feb, 2014 @ 11:04am 
yep, this is a great way. but the only disadvantage is that we need a Genius. The requirement of Tech is the highest among all three. In this sense, tycoon the best, the requirement is so low.
Glyphis  [author] 4 Feb, 2014 @ 10:46pm 
A control module can be researched in a laboratory. Besides that, using a specialized island like yours is a great way to provide energy for your islands. I use that technique as well.
二猫 4 Feb, 2014 @ 5:57pm 
normally I select 1 small island as the "nuclear island", building 5 or more nuclear plants, then transmit to some big cities. This is super cheap.
二猫 4 Feb, 2014 @ 5:52pm 
Thank you Thomas! how? buy a control module? or natrually -100%?
Glyphis  [author] 3 Feb, 2014 @ 10:14pm 
Upgrades can reduce the risk of tsunamies with up to 100%. You might want to try those out ErMao.
二猫 3 Feb, 2014 @ 5:37pm 
I suggest Geothermic power plant not build with Oil Rig, otherwise Sunami will screw a lot.
Glyphis  [author] 30 Jul, 2013 @ 7:56am 
ah ok tnx :P i'll patch that one right now

It should be "Comparison Tables", if that's the word you're looking for. "Comparising" isn't a word. Great guide! Just wanted to help you out :p
