The fund CSI Energy Index, which tracks this index and uses it as a benchmark for performance comparison, has two index funds according to WIND's data:

Among them, Huitianfu CSI Energy ETF is a fund that completely replicates CSI Energy Index and is based on 100% CSI Energy Index;

Changxin CSI Energy Internet is based on CSI Energy Internet Theme Index.

I compared it. There is a big difference between CSI Energy Index and CSI Energy Internet Theme Index. The CSI Energy Index is mainly composed of Sinopec, PetroChina and coal oil.

CSI Energy Internet Theme Index is mainly composed of lithium batteries and new energy.

Therefore, there is only one ETF in the real sense, and that is Huitianfu CSI Energy ETF.
