Hydroelectric and solar photovoltaic energy, and wind power, and fossil fuels, are all non-renewable in the several billion years time scale, since they are all byproducts of the energy gradient caused by the sun's electromagnetic radiation hitting the Earth assymetrically, and that nuclear process will eventually burn out, and before that change to a level that won't sustain life here.
So the term renewable is actually a functional term which has a time span parameters i.e. renewable(cycleLengthLow, cycleLengthHigh, maxOverallDuration ) which is true for certain ranges of duration for different energy exploitation technologies. Hydro-electric then, if used to a level that reduces buffers, is renewable(1y,1y,5billion y), solar pv is renewable (1d, 1m, 5billion y), etc. where as fossil fuel use (at buffer exhaustion consumption rate) is renewable(100m y, 500my, 5billion y).
Roughly.
