The point is that the alternatives aren't "green" and their implementations are mature, arguably even better understood than RSA and its implementations.

Switch to other proven and mature algorithms eg libsodium, Tink, etc. RSA has not been the only game in town for a long time.

There are many other algorithms that are just as proven but don't feature many of the traps contained in RSA. The main issue with RSA is that depending on implementation and context-sensitive parameter selection (i.e. you actually have to think about them and can't just always use the same) you get wildly different results. Other algorithms, like ECC, also have parameters, but they aren't context-sensitive, so always choosing the same one is fine for developers and only security researchers have to think of new and better parameters. The Question really is how brittle do you expect/accept your encryption algorithm to be: RSA is very brittle in very unexpected ways, while e.g. ECC is only brittle if you choose a bad curve (but you can simply always select the same safe one) and people also know that.
