Human life is mainly dependant on metals, or, to be precise, on the various tools made out of metals. On the same lines, metal tools and materials are mostly being made in furnaces, where, metal is melted and then re-solidified into finished commodities. But, the adverse factor that lies here is that furnaces use non-renewable sources of energy. These are not only getting depleted day by day but are also creating bad effects on environment due to their by-products formed on burning them.
