First of all, all of this was decisions by the previous government, which indeed did not do enough to sustain the switch to renewables. The new government would have changed this anyway, the energy scarcity gives this an additional push - now everyone can see how much cheaper renewable energy is over all.
The payments from the EEG-Umlage are not stopping, it is just the financing of them. One problem of it was, that it was paid mostly by the consumers and small businesses. Basing it on taxes ensures a more fair financing.
I am sure, next will be a lot of law changes to facilitate a quick build up of renewable energies. Especially as now the FDP is also pushing for this, before they were quite reluctant.
