日本和美國是公認(rèn)的鋼鐵能源效率的領(lǐng)導(dǎo)者，歐盟一些鋼廠能耗也有很大的降低，蒂森克虜伯杜伊斯堡廠、塔塔鋼鐵艾默伊登廠和安賽樂米塔爾根特廠都已經(jīng)實(shí)現(xiàn)能源自給自足，并能將剩余電力出售給所在國家電網(wǎng)。俄羅斯鋼鐵企業(yè)也在提高能源利用效率，進(jìn)一步提高全球競爭力，而一些中歐國家鋼鐵企業(yè)則失去了能源自給的機(jī)會，因?yàn)榭紤]到污染問題他們已將焦?fàn)t關(guān)閉。投資新設(shè)備和新技術(shù)實(shí)現(xiàn)節(jié)能可能會擠壓企業(yè)利潤，但未來在節(jié)能方面的投資還將增加，在市場競爭日趨激烈的環(huán)境下，能源效率是關(guān)系到鋼廠未來生存的大事。
