A fancy $5 coffee drink looks, tastes, and smells different from a 50 cent cup of coffee. A kilowatt hour of electricity that came from the dirtiest coal plant in the universe and a kilowatt hour of electricity that came from whatever the cleanest source is are completely indistinguishable when they come out of my sockets and go into my appliances. |
