Which conformation of an alkane is generally more stable?

The staggered conformation of an alkane is generally more stable than the eclipsed conformation. This is because in the staggered conformation, the hydrogen atoms are as far apart as possible, reducing steric hindrance and minimizing repulsive interactions between the atoms. In contrast, in the eclipsed conformation, the hydrogen atoms are closer together, leading to higher energy and less stability.
