That depends on the speed:

"At maximum running speed human bipedalism is twice as expensive
energetically as estimated for a quadrupedal mammal of the same body size."

"However,at average walking speed (4.5 km h^-1) human bipedalism is
slightly more efficient than is quadrupedalism in the average mammal.."
