U.S. President Joe Biden announced Tuesday that the Department of Energy would release 50 million barrels of oil from its Strategic Petroleum Reserve in a coordinated effort with other countries to lower gas and oil prices.

Professor Michael Powers from Tsinghua University explains that the release of oil reserves will only have a limited, short-term effect.
