All these things are not enough. In 2015, there was an hour when wind power only generated 0.2GW. Hydro and biomass will probably never exceed 10GW combined. Even if you radically reduce the electricity needs down to, let's say, 35GW, you would still have a gap of 25GW. You can't build enough wind power to get this on a day without wind. You need another power source.
