Also, if you are digging a well, you can drop a loop down there.
Once you go below the frost line, the earth is around 68F year round.
I saw this little gem the other day and enjoyed how low tech it was. This is in AZ (Tucson, I believe) so this would not work where one has a real Winter. But actually I'll wager that it could work in a place with a real Winter with some changes (deeper hole for the container, insulated pipe, etc.).
You can effect a form of geothermal. I wouldn't say it's easy to do, but it's fairly understandable how to do it.
It ain't gonna cover your electric bill, but it can cover all or most of your heating/cooling bill.

Would love to make one of those for a shed as an experiment.
That's cool! The hot springs up here has a geothermal greenhouse. I think it's impressive when people figure out how to "nature better".. lol
