The challenge I chose to focus on was finding a way to make use of the extra heat generated from the kitchen while cooking. While researching, I discovered that the world wastes more energy than it uses as heat energy (Harrington, 2015). And NZ households use 47% of their electricity on heating with things like water heating, space heating, and cooking (Electricity Authority, 2018). I thought of re-purposing that wasted heat energy to power that one could use. This would be done through the use of a thermoelectric generator which produces an electric current through temperature differences between high and low temperatures.
