China is investing billions in both renewable energy and non-renewable energy for data centers.

"As they are located mostly in the east of the country, the data centre electricity supply in China today is dominated by coal with a near 70% share, followed by renewables with nearly 20%, nuclear close to 10% and natural gas accounting for the remainder. Between 2024 and 2030 coal remains the largest source of additional electricity for data centres, with annual generation increasing by nearly 90 TWh. Renewables, mostly solar PV and wind, add nearly 90 TWh over the same period, supported by an increase in the share of renewables in the grid electricity mix, provincial co-location mandates and policies to prioritise the construction of data centres in renewables-rich western China. After 2030 the introduction of SMRs significantly boosts the nuclear share of the data centre electricity mix. Between 2030 and 2035 the rise in renewables and nuclear pushes coal into decline. By 2035 both sources together make up nearly 60% of the data centre electricity supply in China."

I think the race for Anthropic is more about getting the bag and exiting ASAP.

Scaling renewables is slow, they need data centers now. One of the big problems in the US right now is getting enough electricity into your DC. Nobody wants to spare capacity, since it has already upset the electricity prices in the last 6 years and inflation is a hot topic.
