I find that there are two posts on reddit that addressed the same request of using green energy. And the admin of the protonmail subreddit did reply.
Here is the reply in 2019:
"Yes, we care about the environment as much as we care about privacy. We look to always choose the most eco-friendly option for our energy needs. As a matter of fact, we’ve used only hydro energy for a long time in our initial data-center. With time we couldn’t keep the percentage 100% hydro and had to diversify, but we are constantly working towards this direction. Needless to say, all our offices recycle everything we use. Planting trees is not a bad idea either, we will think about ways to implement this in our company’s culture. ProtonTrees maybe? ;)"

Here is the reply in 2021:
"Hi, thank you for your interest in ProtonMail! Our Frankfurt and Zurich data centers are
ISO standard 50001 certified and run on 100% green energy. We’re also working to further reduce our carbon impact where possible, as we care about the environment as much as we care about privacy."
