  Given a graph $G$, let $G^\sigma$ be an oriented graph of $G$ with the
orientation $\sigma$ and skew-adjacency matrix $S(G^\sigma)$. The skew energy
of the oriented graph $G^\sigma$, denoted by $\mathcal{E}_S(G^\sigma)$, is
defined as the sum of the absolute values of all the eigenvalues of
$S(G^\sigma)$. In this paper, we study the skew energy of random oriented
graphs and formulate an exact estimate of the skew energy for almost all
oriented graphs by generalizing Wigner's semicircle law. Moreover, we consider
the skew energy of random regular oriented graphs $G_{n,d}^\sigma$, and get an
exact estimate of the skew energy for almost all regular oriented graphs.
