The TSM 371 Residential Housing class analyzed the simple life cycle cost of 5 different bulb selections for a utility room (12' x 15') requiring 9,000 lumens of lighting. The bulb choices were: 8 incandescent 75W bulbs vs 12 CFL vs 3 different LED bulbs. Local pricing was used for this homework. LED bulb life was 11,000 hours, CFL life 6,000 hours and incandescent life...a dismal 750 hours. All technical info straight from manufacturers' spec sheets.
Update!
On January 19, 2018, Friday, EPA filed a motion with the D.C. Circuit Court of Appeals to further delay issuance of the mandate. Please check EPA's website to reach recent information on the court mandate.

Mark your calendars:
The 2018 Illinois Pork Expo is February 6-7, 2018 in Springfield, IL.
Some of the rules and setbacks for manure spreaders in Illinois were changed by the 2014 EPA AFO/CAFO rules. Commercial manure haulers and farm operators can learn how these rules—which address ALL livestock facilities in our state—affect their operations, by attending one of the four regional meetings being held this spring. This is an important, unique opportunity to hear Illinois rules clarified by experts. Speakers include IEPA regional Environmental Protection Specialists, U of I Extension faculty and educators, and agricultural commodity group representatives.
Each spring semester, students in the Animal Science 403 pork production course get a brief introduction to ventilation fans, air inlets, environment control and manure management. Today, we share the information about the BESS lab in Agricultural and Biological Engineering at U of I. A unique laboratory, BESS conducts ventilation fan performance testing for companies, and posts results in an online database that anyone can access and use to select fans.

Nitrogen-limiting and phosphorus-limiting nutrient budget worksheets are now available online. Swine, beef, and turkey producers can utilize these online worksheets to easily calculate their manure application rates.
