    Not only is aluminum (aluminium if you are British) recycled frequently, it is recycled economically. Even more, when aluminum replaces heavier steel products in transportation, it saves energy for the life of the vehicle because it takes less energy to move less mass. Although aluminum is not as good a conductor as copper, it is used in transmission of electricity because using thicker aluminum wires still weighs less than an equivalent amount of copper to do the job. This saves money on the actual wires and allows the towers that hold the transmission lines to be less massive. This is fine in places where the air cools the wires. Do not use aluminum in household wiring because it will overheat inside walls and may cause a fire.

    Think wind and sun. But this will get you thinking possibly the other way due to recycling: "Water can be considered a renewable material when carefully controlled usage, treatment, and release are followed."

    I think to be regarded as renewable it must be a living thing, like plants or livestock.

    aluminum can be recycled over and over. Please explain the term "renewable" a little better.

      I agree

      Renewable refers to Earth's power/energy to replace an item(s). I good example is metal, once used, does not reappear or multiply.

      I guess we got the conversation going, didn't we!!! You had a very good question, I needed it clarified as well.

      Aluminum is very plentiful in the earth's crust, but is not economical to refine into the metal unless it is found in high concentrations like bauxite ore. Most clay soils have aluminum in them, but in concentrations so low that you would go broke trying to extract the aluminum. Before the electric arc furnace was invented, aluminum would have been considered a precious metal that cost more than gold or silver to produce. Even today, aluminum smelters are almost always located close to hydro-electric dams. They produce the cheapest electricity, after the enormous expense of building the dam is borne by taxpayers. Water flows through the dams because of gravity. Gravity is totally free.
