@manton I see this as a clear opportunity. This is not a Linode issue, rather this is a Micro.blog issue as you choose Linode. Being an indie platform that is also powering its infrastructure (no matter how small it is right now) from renewable sources is still a very positive message - clearly the rest (except those powered by Google) don’t give a monkeys, so this is a clear gap.
You don’t have to be running on renewables from day one, rather there might be different things that you can implement that take you in that general direction. Ask Linode, how they power your servers, maybe they have options available?
