We discuss several possibilities to explain fast radio bursts (FRBs) — millisecond extragalactic bursts of radio emission with detected fluence from 0.1 Jy up to >100 Jy. About 20 different hypothesis have been proposed to explain this phenomena. Conjunction of observational data suggests that sources of these events are neutron stars. After a brief review of observational results and variety of proposed explanations, we focus on the magnetar model ([1, 2]), and on some aspects of the model of superstrong pulses of young energetic radio pul- sars ([3, 4]). We discuss statistics and energy budget of FRBs in these scenarios. We conclude that at the moment several explanaitions remains possible, and the population of FRBs can be a mixture of sources of different types. The repeating FRB can be either source different from the rest of population, or and examle of the same type of sources caught during a brief period of enhanced activity.
