The percentage of electricity produced with gas in Italy is ~63/64% (Terna data, 2022). The other obvious solution would be to place a bunch of solar (PV) panels on the roof. These are 50% deducible in your taxes in the next 10 years. You can do that also in condo. The upside is that by design the excess energy is sold to the local network, powering other apartments/houses locally. You can also join a solar community. You can also decide to buy only certified energy that comes from hydroelectric or pv or eolic (see for example Dolomiti's offers) and compensate CO2 produced by energy and/or gas at home with certificates (as well, Dolomiti's offers). Our solar, since Jan 1st, has produced over 4 MWh of power, of which 1 was used by us and 3 were used by other apartments in the building (and we got paid for it, even if just a little). Regarding floods, yes, it was bad. But many reasons are linked to anthropic (mis)use of the soil. You can (if you read Italian) read up a bunch of things written by the Wu Ming collective commenting the whole event. I am considering emigration as well, but for other reasons.
