Episode notes
China's Dual Energy Landscape
- China leads global wind and solar installations with up to two-thirds of new projects.
- Despite this, coal power still grows but is expected to plateau soon.
Hematite vs. Magnetite Ore
- Hematite ore is easier to use in blast furnaces despite lower upgrade efficiency.
- Magnetite ore upgrades better but is less suited to traditional blast furnace use.
Electric Smelters vs Arc Furnaces
- Electric arc furnaces need high-grade iron or scrap steel to efficiently produce steel.
- Electric smelter furnaces can use lower-grade ore by fully melting it with electricity.
