Grand Prize Winner

- Matt Meshulam and Zach Dwiel

The EnerJar took top prize of the design competition—both a favorite of the judges and the crowd at the Greener Gadgets Conference in New York City. The EnerJar is an easy-to-build, DIY device that accurately measures the power draw of electrical appliances. Sitting between any wall outlet and the appliance (think blowdryer versus laptop), the EnerJar helps users gain an understanding of power draw, investing them in the knowlege, and leading them to reduce their electricity use.
