We study the implications of the recently proposed Trans-Planckian censorship conjecture (TCC) for early Universe cosmology and in particular inflationary cosmology. The TCC leads to the conclusion that if we want inflationary cosmology to provide a successful scenario for cosmological structure formation, the energy scale of inflation has to be lower than 10(9) GeV. Demanding the correct amplitude of the cosmological perturbations then forces the generalized slow-roll parameter e of the model to be very small (
