I am pretty sure that you still can get a monthly/yearly ticket for your local area. These are usually between 50-100 € in Germany. In Vienna you pay 1 € per day, so around 350 € for a year.
The idea here is that you have one ticket that can be used everywhere in the country, so you probably would only get it if you travel more than a local commute on a regular base.
I am currently reading Kim Stanley Robinson's Mars trilogy [1] where vulcanos and melting ice play some role in survival on mars. And in general it's a great read.
