The Pink Palace in Atlanta’s Buckhead area is a shining example of how beneficial it can be to remodel your home for energy efficiency. This famous 82-year-old home is a six-bedroom, stucco mansion that is definitely Old South. Recently, it has been under several renovations, including removing 18 layers of paint. The most notable improvement, though, is that it has now been fitted to use geothermal energy. According to Luxist, this transfer turned a $6,500-per-month energy bill into an affordable $150 a month bill. Now that, ladies and gentlemen, is efficiency.
