A gas dryer uses either natural gas or propane. B. Hang the clothes on the line and wait 2–8 hours. What Do You Think? Both drying methods use kinetic energy in some form as the primary source of drying power. When we use energy, we either convert potential energy into kinetic energy, or capture kinetic energy and direct it toward accomplishing a task. We often have a choice of energy sources available to us. WE GET ENERGY FROM THE ENVIRONMENT ? Both drying methods use kinetic energy in some form as the primary source of drying power. What is that kinetic energy? Which method uses nonrenewable resources (i.e., resources that can’t be replaced, like fossil fuels)? Can either or both of these methods be considered to use nonrenewable resources? Challenge: Where did the energy in fossil fuels come from?
