While trying to take minor steps towards reducing the electricity consumption at our home, on an online forum (sorry can't recall the original source) I read that if the oven and the fridge are close to each other, the heat from the oven will make the fridge work harder and therefore use more energy -- this make immediate sense to me!
At home we have a setup where these two devices are close to each other, and there is no good isolation from the oven towards the fridge. What is the best way that I can isolate the heat radiating from the oven?
I thought of using styrofoam between the two devices, other suggestions included a big metal (steel) plate? Any other alternatives? What's best?
