The power bar.
A spare oil resource, and a derrick hard at work.
Энергия
In real life, money is power, but in Warzone, power is money. You spend power to build structures, manufacture units, and research upgrades/new technology.
Getting Энергия
So how do you get power? Энергия is generated by Oil Derricks. However, you must have at least one Энергия Generator for every four Oil Derricks.
Oil derricks must be built on oil resources, but the generator can be anywhere on the map. Keep in mind that additional generators beyond one for every four derricks will provide no benefit.
Pricing
Icons in the Производство, Строительство, and Исследования menus will have yellow bars in them representing their price:
Inexpensive weapon
Expensive weapon
When you place your mouse over an icon, the power bar will have a green section, representing its price. If you cannot afford it, the power bar will instead turn red.
The amount of power you have is shown on the very left of the power bar. If you place your mouse over an icon, if you have enough power to get it, the number will show the amount of power it will cost. If you can't afford it, the number will show the amount of power you need to be able to afford it.
Энергия is drawn as soon as a the icon is clicked. Providing you have sufficient power for the activity, the initial progress bar fills quickly with green (slower with more costly actions) and the construction or research begins. A yellow progress bar then charts the progress achieved by the current activity.
Улучшения
Power Generators can have a Энегертический блок built on top of them to squeeze out more power. Power Modules need to be researched before you can build them. There are also several researchable upgrades available which increase the amount of power you recieve.
