Abstract

This paper summarizes the features of hydropower developments and compares hydro with other renewable energy sources for supply to electric power grids. The particular advantages that hydro plants typically provide for grid operation and reliability are then described. Challenges that hydro developers face are then noted and discussed. The paper then addresses the question about sustainability of hydro power developments particularly those in Canada. The meaning of sustainability as currently presented in public discourse is examined and popular applications of this concept challenged.
