Aluminum building materials are also recycled. Producing secondary aluminum involves cleaning and separating aluminum scrap from other materials and melting it down in a furnace, usually fired by natural gas. Compared to the energy requirements of primary production, secondary production is much less energy intensive.
[PDF]Recycling aluminum saves more than 90 percent of the energy that would be needed to create a comparable amount of the metal from raw materials. Tossing away an aluminum can wastes as much energy as pouring out half of that can's volume of gasoline. Nearly 75 percent of all aluminum produced is still in use today.

Milling Horsepower Calculator. Calculate the horsepower required for a milling operation based on the feed rate and depth of cut, which are used to determine the material removal rate (or metal removal rate). Also required is the unit power, which is a material property describing the amount of power required to cut that material. ...
Energy. Energy is the capacity to do work (a translation from Greek-"work within"). The SI unit for work and energy is the joule, defined as 1 Nm. more energy units; Moving objects can do work because they have kinetic energy. ("kinetic" means "motion" in Greek). The amount of kinetic energy possessed by an object can be calculated as
