As I write this, my office is lit by (5) 13W CFL bulbs, sent to us for FREE from our power company.
I contacted Duke Energy when I heard about a program that they offered: Duke Energy wants to help our customers save energy and money. We’re giving eligible customers free compact fluorescent light bulbs (CFLs) to jump-start their savings. CFLs use 75 percent less energy and last 10 times longer than incandescent bulbs.
Contact your local power company to see if they offer a similar program.
