The Anderson County board of supervisors has agreed to fund an ambitious project that will "spend money now to save much more money in the future." A total of 16.2 million will be awarded to the York Corporation for energy improvements in 40 buildings, 27 parks, and 37 traffic intersections. These improvements include lighting upgrades, solar hot water collectors, more efficient heating/cooling systems, and LEDs for traffic signals. Bonds paying 7% per year over the next 15 years will be used to pay for these improvements. If the annual savings fail to average 2 million, York Corporation will reimburse the county the difference. Will York need to pay any money to the county? If so, how much.
