We point out that the swampland conjectures forbidding the presence of stable<br />
de Sitter and non-supersymmetric anti-de Sitter vacua require the presence of a<br />
dynamical axion for the electroweak SU(2) gauge theory. The potential energy of<br />
the electroweak axion provides an attractive candidate for the dark energy. We<br />
discuss constraints both from the weak gravity conjecture and from<br />
observations, which can be satisfied elegantly in a supersymmetric extension of<br />
the standard model.
