Oil price hit down due to the extended lockdown, we still don't know when the pandemic will be resolved so countries are hesitating to stock the crude oil because more longer they store then the more expensive they will face and also some countries are in need of funds for a medical emergency which left the oil untouched so prices went down too much.
I honestly hope this could lead countries to use more of renewable energy instead if such unreliable resource like oil.
In couple decades when oil will be gone - those countries who were smart enough will have enough energy (like Australia for instance)
