Whether you own a dairy farm or run a dairy processing plant, the one certain sustainable best practice should be improving the efficiency of your lighting. And while early adopters jumped on compact fluorescent lights (CFLs), today the visibly superior product is the light emitting diode bulb, more commonly known as an LED. In my mind, LEDs, while costing more initially, are far better and more cost-effective in the long term.
According to the Environmental Protection Agency, both CFL and LEDs use about 80% less energy than incandescent bulbs. The agency states that a traditional incandescent bulb will cost about $7.32 per year to use, while a CFL will run about $1.57, and the LED will be about $1.50.
