In 2017, the amount of energy produced in the United States was equal to about 875 quadrillion Btu, and this was equal to about 896% of US energy consumption The difference between the amount of total primary energy consumption and total primary energy production was mainly the energy content of net imports of crude oil
Outotec's ferrochrome smelting technology combines preheating and electric furnace operation to optimize electric energy and coke usage The built-in ability to clean and use process gases decreases operating costs and emissions The superior availability of the process enables higher ferrochrome production capacity
The US saw booming energy production largely driven by oil and natural gas, as well as renewables such as wind and solar
And an immigrant who moves to the US is likely to consume far more energy just by moving here Even if he scrimps and saves energy at home, every thing he buys will increase consumption of energy and other resourc Data courtesy of BP, "Statistical Review of World Energy 2007;" and Wikipedia (compiled from various sources), 2007

Ash Composition on Energy Consumption The ahs composition of the selected reductants includes 5-15% SiO2, 3-7% Al2O3 with less than 2% of CaO, MgO and FeO It seems that the energy consumption of ferrochrome production rises with an increases of ash contents of both SiO2 and Al2O3, see in figure 9
Turkey maintained its chromium production in 2017, retaining its position as one of the world’s top chromium producers It put out 28 million MT, the same amount it produced in 2016
energy consumption for production of ferrochrome is relatively high and it varies between 2000 kWh/t alloys with pre-reduction to 4000 kWh/t alloy without pre-reduction and feed preheating Depending on the furnace size, the energy consumption and production rates are different  Smelting
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): High carbon ferrochrome production process is energy intensive, consumes approximately 3300-3400 kWh per ton of metal produced This amounts to ~ 34 % of the total ferrochrome production cost The power costs in India are almost 4 times greater than the leading ferrochrome producing countries like South Africa
