text: how much energy is produced in the production of steel, and of glass? how could they be reduced? i am trying to find out how much energy is produced both by the construction of steel and glass individually? on knowing this i then want to find out how each of these could be reduced they take an awful lot of energy to smelt them, either one. generally, the melting point of alloys is lower than the melting point of the individual ingredients, so perhaps an alloying material could be discovered/ developed, which would reduce the temperature at which the steel or glass had to be melted. if you can do that, you'll be rich. good luck!
