I am yet to see systemic renewable power source that is available to country like Germany (or Poland where we also have discussion about going nuclear).

All renewables available to us are considered supplementary (they generate power when conditions are favorable, eg. wind blows, sun is shining). But this means they can’t be used to maintain power grid.

Ofc you can try hydro or geothermal, but those depend on your river network, underground warm waters availability, as well as population density around country. Those work for country like Norway but in practice German increasingly relies on French nuclear power as systemic source to maintain their grid, and Poland (sadly) sticks to coal and gas.

Renewable most of the time allows to keep reserves and use them when necessary.

Also the renewable story is not just solar and wind but also short term energy storage.

The dependency to Russian gas is only 30%. Adding more thermal solar energy on roofs and bigger heat water storage is relatively easy to achieve.

Of course Germany should have pushed renewable even further and we did not. It's frustrating to see so little solar panels in cities.

What are those reserves? How are they supposed to work? Can you store enough reserves to power the town?

Oil and gas reserves.

They are tanks.

If you use solar heat to support your oil or gas, you will be able to reduce your fossil fuel consumption noticable
