Expert discusses future of smart grids
August 30, 2013
A series of workshops on the Purdue campus is exploring how to improve the reliability, productivity, and cost of electrical utilities.
GE digital energy executive and Purdue grad John McDonald says smart grids are the best way to guarantee the long-term sustainability of the power industry.
He says the systems will give consumers more control over energy use in their own homes.
McDonald admits there will be a learning curve for the public, but the cost savings will be worth it.
He says using smart grids, consumers have the potential to save 20% or more on their energy bills.
McDonald says there are currently a lot of employment opportunities in the field.
He says students who take courses and complete internships in power and electricity will have the necessary skills to secure a job.

The recent recall of hoverboards because of exploding lithium-ion batteries highlights the danger of overheating batteries. Amy Marconnet, an assistant professor of mechanical engineering, can speak about the effects of excessive heating in batteries. Marconnet (pronounced mar-co-nay) founded the Marconnet Thermal and Energy Conversion Lab, where researchers are dissecting the batteries and testing materials making up electrodes and a critical component called a separator. (A video is available at https://www.youtube.com/watch?v=qCTMA8sxZO0) Battery failures have been reported in products ranging from commercial airliners and laptops to hoverboards and cellphones. Chemical reactions in the batteries generate heat while discharging and charging. The separator is a layer of material between the positive and negative electrodes. When it fails due to high heat, the battery short-circuits and could explode.Read Full Story
