Homeowners and businesses often waste power because they aren't aware of all the steps that can be taken to reduce their electricity consumption to lower bills and help ease strain on the nation's power grid, says a Purdue University expert.
"We need to help consumers more than we do," says Athula Kulatunga, an associate professor of electrical and computer engineering technology and a certified energy manager. "Studies have shown that people want to be more conscientious of their energy usage but don't know how they can make a difference."
Kulatunga says simple actions such as installing a digital thermostat, insulating water heaters and adding insulation to a home's attic and walls can result in significant savings. There also are new technologies being used and researched by utility companies that can go even further.

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
