There are only so many rivers you can dam, so much surface you can put solar panels on without taking away from agriculture, etc.
And a full-renewable approach also has huge risk, it relies on storage technology getting much better in the future, otherwise you need either fossil fuels or nuclear to cover dips. Diversifying probably makes sense.
