This may affect the price of electric energy, enabling processes where the electric energy is relevant, as for example secondary metallurgy where arc furnaces have large applications. Here we will discuss the impact of the new methods of energy generation on the cost of steel production in the next decades. It is forecasted that the price of electric energy will continue high in the next 5-10 years, while the coal energy plants were not completely replaced by wind or solar. Also, energy storage is expensive , and this precludes price energy reduction. The high price of energy storage is a significant bottleneck concerning price reduction of energy. Energy can be exported as a reduced metal, and countries with surplus of electric energy can become exporters of metals for countries with energy deficit. Brazil has one of the best conditions in the world for wind energy production in states near the equator line as Rio Grande do Norte and Ceará. These states are also promising places for production of other reduced metal, as for example aluminum. |
