Why is insulating our homes save burning fossil fuels?
Insulation maintains your desired indoor temperature for longer. In the winter, it keeps warm air inside by keeping cold air out. In the summer it keeps cool air in and warm air out. It acts as a barrier between your desired temperature inside and the unwanted temperature from outside. If you can keep the air inside cooler for longer, you don’t have to run you AC as much — which is run on electricity. If you can keep the air inside warmer for longer, you don’t have to run the Heater as much — which is also run on electricity. It keeps from burning fossil fuels b/c it reduces per home energy consumption — which as you know has to come from burning coal, wind, solar, natural gas or from a nuclear source. Take into account the transportation of materials to keep up w/ demand if no houses had insulation. Per house consumption would go up a little — but the aggregate consumption of all houses would require a huge increase in energy. That means more mining, more transportation, and more
