Energy

Energy

A Sim and his cat sleep on a bed.

Sims' energy slowly decreases while they are awake. If a Sim runs out of Energy, he/she will collapse from exhaustion, and fall asleep on the floor. Sending a Sim to work or school with low energy will harm their performance. While they won't collapse from exhaustion away from home, they can do so as soon as they return – and then they'll just be an unconscious Sim littering the pavement. If their energy drops too low while eating, they will fall asleep on their plate.

In The Sims Social, this need was renamed to Sleep, possibly to avoid confusion with Energy in that game.

Sims can replenish their energy by sleeping. Toddlers will awaken whenever their Energy bar reaches 100%. Older Sims will awaken at midnight if their Energy bars are at 100% by then. Otherwise, children, teens, and adults will automatically sleep until 6 am or until their Energy bar is back at 100%. Elders who are asleep past midnight will usually awaken shortly after their Energy bar reaches 100%. In The Sims 3, the player can drag the action handle to specify a time for the Sim to wake up.

If a Sim needs a quick boost of energy, they can drink coffee or espresso (although children can't do that). Sims can get coffee from a coffeemaker or an espresso machine. Sims can buy an espresso from the espresso bar while on community lots, but really, the best thing to do is simply have your Sims go home when they get too exhausted, as coffee and espresso decreases bladder, and may have other side effects.

Sims also gain energy from sitting down. Sims can also take naps on lounge chairs, recliners, and sofas, but napping doesn't replenish energy as well as sleeping in a bed, and active Sims may wake up before they're fully refreshed.

Sims will not die from exhaustion, though if they become extremely tired while in a pool, they can drown.

Equivalents for other life states

The Sims 2

For Servos, the equivalent of Energy is Power. Servos can replenish this by sleeping or napping, the same as Sims can. If it's daylight, they can use the "Recharge" self-interaction to go outside and stand in the sun until their Power is replenished. If they are in gold or platinum aspiration, they can also restore their Power by using The Eclectic and Enigmatic Energizer or drinking the Elixir of Life. If the Power need gets too low, a Servo will either go outside to recharge, or go berserk and require repairs by a Sim with high Mechanical skill, preferably one with a gold talent badge in Robotics.

For PlantSims, the need for sunlight has many aspects of the Energy motive. If a PlantSim's Sunlight need becomes too low during the day, the PlantSim will go outside to be in the sun. If the Sunlight need becomes critically low at night, the PlantSim will go outside and collapse, and will revive after dawn the next day.

Note

The MaxMotives cheat will not restore a Servo's Power motive or a PlantSim's Sunlight motive.

The Sims 3

For SimBots, the equivalent of Energy is Charge. SimBots recharge while sleeping, but can also recharge if they get electrocuted. Mummies do not have an Energy mMotive at all, but move very slowly. At night, a vampire's Energy decays much much slower between 6:00 PM and 6:00 AM.

For Aliens in The Sims 3: Seasons, Energy is replaced with Brain Power when they become teens.

For Plumbots, the equivalent of Energy is Battery Power. A Plumbot recharging station is available in Buy mode, and Plumbots will recharge while shut down. A Plumbot with the Solar Powered trait chip will gain Battery Power while outdoors in daylight, but the chip may not always provide enough power to completely offset the power drain caused by whatever the bot is doing. Plumbots can siphon power from appliances, but at a cost to their Maintenance need.
