It is suggested that dark energy is the energy of the Hawking radiation from a cosmic horizon. Despite of its extremely low Gibbons-Hawking temperature, this radiation could have the appropriate magnitude O(Mₚ² H²) and the equation of state to explain the observed cosmological data if there is a Planck scale UV-cutoff, where H is the Hubble parameter.
