Here’s a bit of green celebrity real estate fluff to help ease you into the workweek (yeah, it’s Tuesday but we all need some extra easing after long, food-centric holiday weekends):

Back in late October, tireless toilet paper conservationist, animal rights activist, erstwhile Michael Jackson backup singer, and all-around green queen Sheryl Crow put her solar-powered equestrian estate (real estate speak for fancy horse farm) in Tennessee up for online auction after it failed to snag any buyers when initially entering the market back in May for $7.5 million. But a month later with the bidding now closed, it looks like Crow still hasn't found a buyer.

Crow purchased the 150-acre property, Cross Creek Farm, in 2006 during a time that she was most likely seeking a bit of countrified seclusion: she had recently ended a high-profile relationship with Lance Armstrong and was undergoing treatment for breast cancer.

Located in rural Williamson County outside of Nashville, the estate includes a five-bedroom, 10,624 square-foot "hulking and architecturally insignificant" main house, a saltwater pool, guest quarters, a recording studio, and, according to The Tennessean, dual solar systems capable of reducing electric costs by approximately 40 percent. The horse farm on the property includes a 14-stall barn and an indoor riding arena.

Word is that the Missouri-born musician won't be decamping back to her previous home, Los Angeles, but will remain in the area as she wants to stay close to her family. Here’s hoping that Crow will also be opting for smaller and more efficient digs. Sure, it’s great that the estate runs partially on renewable energy, but a 10,624-square-foot backwoods Versailles with a six-car garage and gigantic fish tank in the kitchen seems a bit much for such an outspoken environmentalist.

The online auction of Cross Creek Farm closed last week after Crow rejected the highest bid (the auction was conducted with a seller’s reserve meaning that she could pass on the highest bid if she found it unacceptable). No word when and if Crow’s luxe “solar farm” will return to the auction block.
