As far as space I don't know, but I do know for aluminum cans there is a benefit in the amount of kilowatt*hours (Anyone else wonder why we just don't say Joules in the US?) saved. I believe the number is crazy too, like > 90% of the energy is saved by recycling the aluminum.
- greenpresident 12y agoMost of the energy is spent reducing the bauxite, an ore of aluminum that is the world's main source of aluminum. Once that's done, you don't have to spend it again.
- ralmeida 12y agoWe say kilowatt-hours in Brazil too. Since it's a SI unit, I believe other countries use this too. It's probably because it's a more convenient unit to use when talking about electrical energy consumption, because 1 watt-hour is the energy consumed by something that has 1W of power running for one hour. One kWh is 3.6 megajoules, so it would be less convenient in this context.
- cwal37 12y agoJoules are mostly used as a scientific term. BTUs and kWh in turn are kind of like industry terms that came about with the steam power revolution and still define heat/energy production in most countries today.
