- DOE luminary sheds light on the bright future of energy efficient bulbs
"I see a real innovation in the LED space that allows many companies and residential communities to get involved more aggressively," says West. "As technology matures and changes, we see prices dropping as well, which makes the LED bulbs more attractive to the public."
- David McKinney: Clean Light, Green Light is lighting the future
"Our biggest battle with LED lighting is controlling the heat," says McKinney. "By controlling the heat, we can create a light that will last 50,000 hours or more. Across the country and across the world- energy rates are raising; while our product does cost more upfront, the pay back is much quicker compared to traditional lighting."
- MSU leading the way in green packaging
Hotchkiss believes the main challenge ahead for the packaging industry revolves around the feed stocks used to manufacture packaging and the performance standards of these materials. "The challenge is to take renewable resources and turn them into packages that have equal or better performance standards."
- Cliff Lampe: Web-based communities enhancing sustainability
Lampe is working on the Advanced Michigan Project with MSU Extension and the Michigan Agricultural Experiment Station. Every five years MSU Extension has a mandate to census the area to collect feedback from the residents of Michigan.

Ryan Vartoogian is president of Spartan Internet Consulting, which he founded in 1997 as a sophomore at Michigan State University. Vartoogian adds that there is a strong "green" consciousness throughout the high-tech industry.
Don Morelli: Transferring waste heat into electricity
- Don Morelli talks with Kirk Heinze on WJR
Whether energy is converted from wind, solar energy, or coal, energy is lost in the form of heat and Michigan State University’s Don Morelli is looking at ways to make use of that wasted heat.
“If you look at how energy is transferred through our economy from source to its use, say from the coal mine to the light bulb, or from the well head to the automobile, a large portion of the energy we use is lost, something like two-thirds of it in the form of waste heat,” Morelli says.
Morelli is a professor of chemical engineering and material science at MSU and is part of a leading research team that aims to take wasted heat energy and turn it into thermal electricity.
As a former GM worker, Morelli understands how thermal electricity can help auto efficiency.
“When we burn gasoline in an engine, something like 50 kilowatts of the 75 kilowatts of energy that is produced is lost either in the radiator or the exhaust as waste heat. If one can convert a portion of that thermal energy—that lost heat—to electricity, one has a means of increasing the fuel economy or the fuel efficiency of the vehicle,” he says.
While Morelli believes the United States should continue to look at wind and solar energy, in the mean time, he says, we should be using wasted heat more efficiently.
“I like to sort of think of this waste heat as our best new energy source because it is energy that is available to us right now, we just have to figure out how to use it.” Morelli says, “When we convert energy from various sources to usable power, of course we inevitably lose part of that energy, it’s not necessarily that we are being sloppy, but we have to play by the rules—the rules and the laws of thermal dynamics which govern how efficient energetic processes are. But if we can recapture some of the lost heat, and turn it into usable energy, this is something that can impact our energy usage today.”
