Green energy source

 sources are a unique type of decorative object, introduced in The Sims 2: Mansion & Garden Stuff, The Sims 3 Store and The Sims 4: Eco Lifestyle.

The Sims 2: Mansion & Garden Stuff
In The Sims 2: Mansion & Garden Stuff, purchasing any of these objects fulfills the minor "buy green energy source" want. Households with green energy sources receive a financial credit and, with enough sources of green energy, can generate enough of a credit to offset the amount that would be charged in bills; if this occurs, the bills will not be delivered and a notification will give the amount of credit left over, which is added to the household's funds.

There are two kinds of green energy sources — solar panels and windmills. The objects are found in the 'Miscellaneous' portion of the Decorations section in buy mode. Neither object contributes to the environment score.

"You got Sol" by Stellar Products
Solar panels come in two forms, both named "'You got Sol' by Stellar Products." The first form is a 1x1 panel that costs §600. This panel must be placed on a floor tile, but can also be placed on a roof (as long as there is a floor somewhere below the roof). The second form is a 2x1 panel that costs §1200, and can be placed anywhere on the ground.

The Aerodynamo
The Windmill is known as "The Aerodynamo." It has a 2x1 footprint, and can be placed on open flat ground.

The Sims 3 Store
Green energy sources return in The Sims 3 as freely downloadable items from TheSims3.com. A windmill and a solar panel are available. When placed on the lot, they will reduce the bills of the household, much like in The Sims 2: Mansion & Garden Stuff.

The Sims 4: Eco Lifestyle
Like in previous games, the usage of wind turbines, dew collectors and solar panels will reduce a household's bills.
