1 tonne of steel requires around 5MWh of energy at 50,000 tonnes per day it's around 250GWh of batteries at 50% usage. The largest planned BESS is 19GWh. As I said solar+BESS is impractical.

Wind is more expensive. Onshore wind turbines have higher variability. Offshore ones are limited to coastal areas. Overall, there's a lot of practical problems. It's all doable, but building infrastructure takes time.

China's onshore wind potential is 12.6 PWh/year[1]. China's 2024 energy consumption is 9.85 PWh[2]. It's not much of overcapacity potential. Huh. I though it's higher.
