Hydro - flooding large areas, displacing towns, changing the river water flow in a way disruptive to wildlife, silt backup behind the dam, etc.
Solar - large amount of toxic materials used to produce the panels, huge land use per megawatt of power, impact on wildlife, disposal of the toxic panels after they loss too much efficiency to still be of use.
Every energy technology pollutes over its life cycle. Most studies show hydro and nuclear as the cleanest overall (smallest overall environmental impact).
