From there you could use a percentage of mined funds to buy renewable power sources... small scale wind and solar. Hydro or even marine generation. Reduce the overheads in the long term. Depends on your location

You'll need a clear plan and timeline to communicate to your community investors

Also, demonstrations and training for people in cashing out their crypto into the local fiat currency. That might be a good idea. With a caveat that it might be wise to keep some in crypto to profit from any potential price gains. It could help folks who are not crypto-familiar understand what it's all about; if they can see how it can be traded for real cash money in their hands to feed themselves and their families...

Have you considered documenting the process? I think many folks here on Hive would be interested in what you're doing and sharing it here could generate further crypto income that in turn could be put back into the project

All ideas...

Whereabouts in the world are you located?
