I guess the first step towards the future is new lighting. At least that's what Raleigh, N.C. is banking on. They are going to replace every single public light with brand spankin' new LED's. While it will cost a lot more to purchase LED's, the increased price-tag should be negated by a decreased energy & maintenence bill. Next thing you know you'll be seeing hover boards and Delorian's with flux capacitors all over North Carolina.
