About this app
Energy Efficiency is an interactive science learning app for exploring how input energy is divided into useful output and wasted heat. Tap examples such as incandescent bulbs, LEDs, kettles, fans, cars, solar cells, and running to compare approximate efficiency values. A bulb-switching calculator and quiz help learners connect efficiency with energy-saving choices and purpose.
