I think if you had to pick one it would be hydro. We already have about 8GW of hydro dams in Australia and we are building more.
To put that in perspective, right this minute the national grid has 18GW of power coming from coal. In practice we usually only draw from the lakes when they’re full (about 4GW of hydro is currently going into the grid)… we really need to start pumping water uphill when the sun is shining instead of relying on rain.
But we don’t have to pick one. We can have a mix of hydro and off shore wind (off sure wind turbines tend to produce power at a more favourable time of day) and batteries and synchronous condensers and thermal mass and gravity storage (that last one holds a lot of promise - very simple idea, I don’t understand why we’re only just taking it seriously recently - https://www.wired.com/story/energy-vault-gravity-storage/)
