All security risks that don’t need to be accessed by the public (document servers, ssh, internal tools, etc…) can be accessed via VPN while the port forwarded servers are behind a reverse proxy, TLS, and an authentication layer like Authelia/authentik for things that only a small group needs to access.
Sorry, but there is 1 case in 10000 where a home user would have to have publicly exposed SSH and 9999 cases of 10000 where it is not needed at all and would only be done out of laziness or lack of knowledge of options.
Though pumped hydro is sometimes opposed by environmental groups because it does absolutely decimate local environments.
I have high hopes for sodium batteries. The ones that have been released on the market are simply perfect (if scaled up) for local grid storage in countries with a lot of space and will hopefully get better energy density in line with Lithium Iron Phosphate with time.
Salt batteries have been the cold fusion of battery tech for like 10 years, but now it is finally coming to fruition. I hope to install a solar installation with salt batteries in 5 years or so, myself.
