Energy is required to perform most actions in CityVille. Energy is essential to building new things for your city. One energy can be replenished every five minutes, so to restore the default 30 energy it requires 150 minutes, or 2.5 hours.
When running out, friends can offer energy (but not their own) to those in need. The most energy neighbors can give in one gifting is 3. Once you reach the point where you are able to send 3 energy to a friend, you cannot send 1 or 2 energy anymore. Energy refills can be either bought for cash or gifted once a player has a certain number of friends.
• Up to 30 Energy can be stored, representing 2.5 hours. To make maximum use of energy, the user must log in every 2½ hours.
• When out of energy, Sam pops up in a screen, asking you if you want to buy more energy or ask friends for some. Sometimes you may be offered 7 energy for watching a 1 minute video commercial.
• Reaching a new level fills the Energy Meter, so it's a good idea to use up your energy just before reaching a new level (when few experience points are needed you could turn in Collection sets that give you experience points, energy or both to achieve the new level).
• When you visit friends, you can earn more than the 30 Energy limit. Visiting neighbors once a day gives one point of energy per neighbor visited, up to your reputation level (ex. reputation level 30 = up to 50 free Energy from visiting neighbors).
• Visiting a newly added neighbor gives 5 Energy for the first time.
•Accepting goods from the active friends franchises in your city also give you one energy for every franchised business.
• Collecting from Daily Bonus gives you bonus energy (starting with +1 for the first day, up to +5 energy for Daily Bonus collected in 5 consecutive days)
