Energy is eaten up en masse in our country, and some of it we never even think about. I discovered that my refrigerator uses around 5.9*10^5 J of energy per year just while operating on a normal day to day basis. This may not mean much to you, but in reality, this translates to around 1.92*10^6 Kg of coal per year. This is a tremendous amount of coal used just to power a simple refrigerator in a household. Now, magnify this by the number of households in the United States and you will begin to see the impact of household appliances on our power supply.
