...use it! My clever boyfriend visited again this weekend and pointed out another wasteful habit of mine - sometimes I cook without using lids on my pots!
If you want a scientific explanation, complete with derivatives and Newton's law of cooling, check out this website, which shows you how you can calculate the efficiency of boiling water.
For the rest of us, we can safely assume that an uncovered pot takes longer to boil, thus requires more energy, since the contents of the pot is losing thermal energy to the surrounding air. An easy way to increase cooking efficiency is to simply use tight fitting lids and to fit the pot to the appropriate sized burner!
This is an easy tip to save you cooking time, money and energy all while helping you to reduce your carbon footprint! But- make sure that you keep a careful eye on the pot, as it will boil over more quickly!
