I have no electricity except solar. It works well for all my needs, technology has solved this depending on your needs and how much money you have.

I have no water except the one I bring when I buy food weekly/every two weeks. I'm still renovating/building so I'll have a well in the future.

I heat my home with wood that I cut on my own property, I enjoy this very much. It's a workout that also produces something of value.

The drawbacks can be many depending on what kind of lifestyle you're after.

Sartre said "if you are lonely when you are alone, you are in bad company".

I do mountain biking, nordic skating and I have a dog; it works for me. A lady friend might be nice eventually :]

It's silent, I can hear my own heartbeat; civilization is 30 min away.

This is in Sweden.
