We're happy to announce that all energy used for powering your encrypted mailboxes now comes from renewable energy. 😀 #FridaysForFuture #GoGreen

Green email is the future: Tutanota uses 100% renewable energy.

Secure email service Tutanota goes green! Use Tutanota as your email of choice to help us protect the environment and to secure your mailbox with built-in encryption.

Tutanota not using green energy was the only major flaw I could find with it when researching email providers. Now I not only feel secure, but also climate smart by using @Tutanota Thank you!
@Tutanota sounds good but from whom (which power company ) do you / your datacenter buy that green energy?

@Tutanota

Any news on that question?

@el_joa @greenfediverse It comes from Norway, via innogy.

@Tutanota @greenfediverse

OK, thanks a lot for the answer, though it was not was I was hoping for! :-(

As far as I can tell #innogy is owned either by #EON or by #RWE (they have been - and I think still are - selling it back and forth, probably to confuse people and for #greenwashing), and both are NOT allies on the path towards #greenenergy.
I wouldn't want for any of them to get my money! :-(

Did you consider other options or will you do so in the future?

@el_joa @greenfediverse Thanks for your feedback. We didn't know that and will look into it. For the servers, however, we don't have much choice as it's done via our hosting partner. It took several years of convincing/pressure until they would offer us green energy at all...
@Tutanota @el_joa @greenfediverse
Any news on this?
Also, since I've been reading the usual flames on reddit about whether "green energy" is green at all, but atm I'm only interested in having tangible clue of genuine and transparent effort as a first step by your side to switch to your service... could you please add a page on your website where the energy providers and your relaying on them are clearly stated? That would make your claims easier to track and give you more credibility. Thanks!
@materhyu No news, sorry. As we host our servers at a data center, we can't freely decide, but we've at least made them switch to renewable energy via innogy. For our office we use a better sustainable provider as here we have the power to choose ourselves.
@el_joa @greenfediverse
@Tutanota This is awesome! I was also waiting for this before making the switch from Posteo.
@Tutanota It will be better when it's powered by nuclear energy.

@Tutanota

I'm still waiting on Tuta to begin using LESS energy, the apps are hardly carbon friendly. They are the heaviest email apps I've used, and still offer a significantly poorer experience on older hardware. While choice of energy providers might be somewhat out of your control, the efficiency of your code is not, and the collective energy draw by your users running your applications, I imagine, is sizable. +1 to cutting client side energy use as well.

@caveman Thanks for your feedback. We are currently working on performance improvements which will also bring benefits in this regard. Stay tuned!
@Tutanota Yet another reason to go Tuta! So glad I made the decision to switch over to real privacy ❤️
@suri Happy to hear that, welcome to the encrypted side :)
