The source of energy for both coronal heating and wind acceleration is long known, but the exact nature of the photospheric energy transport and deposition is still a puzzle. It was long known theoretically, but recent observations undoubtedly confirmed an important role that Alfven waves play in these processes. While the observed spectrum is in the low-frequency range, existing wave dissipation mechanisms favor the high-frequency spectrum that can effectively interact with particles. In this talk, I discuss a new process of the wave energy deposition that is effective for the observed low frequency spectrum.
