Turbine

Wind turbines are the main Energy production device in the game, others being the Core or some modded devices.

Main use
Turbines produce Energy, an essential ressource in all matches. In a match, you end up having between 2 and 10 turbines, depending on match length and your needs.

If you want a turbine to produce energy, it needs to be high so it has most wind, and you need to use materials that don't block wind, such as BG Bracing or Shield (Rope doesn't block wind either but you won't defend yourself with those) if you want it to run at all.

Other info
Turbines' maximum energy production is 44 per second, if you have 100% wind efficiency. If you don't, it'll be X% of 44, depending on the height relative to the wind floor (determined by the map).

This means that a turbine will take a minimum of 38 seconds to pay for itself, more if you don't have 100% wind efficiency.

Turbines can be upraded for 100 metal and 1000 energy, and produce about 1.5x as much as a normal turbine.

Upgrading a turbine takes 15 seconds, which means you'll lose 660 energy, plus 1000 for the upgrade, and produces 67 energy at 100%. This means it'll pay for itself 87 seconds after you start the upgrade.

Turbines are one common target for your opponents to shoot, since they'll have a Resources advantage if they manage to destroy some.

That's why, there are several ways of defending your turbines, the most common is using a Shield in front, since it'll protect them from some weapons.

Another common way of defending is using Sandbags, since they don't block wind by themselves. You need to put one sandbag at the floor where your turbines are, and put a platform at mid-height in order to place a 2nd sandbag, which is some decent defense.

Some players use both Shield and Sandbags to defend their turbines, and some use FG Bracing, which they convert from BG Bracing when there are shots coming, and convert it back afterwards.
