Am I wrong about energy saving? If an old type filament light bulb is 2% efficient at producing light where does the `wasted` 98% go? Surely it is dissipated as heat and therefore warms the house. And If I use the oven to cook a meal it is not very efficient at cooking the meal but the `wasted` heat warms the house..So..I agree that taken in isolation, ovens and LED bulbs etc seem to save power but overall do they? Are we just moving the accounts around? There is a basic law that energy in = energy out....makes me wonder!
