S2 E5: Ranking your travel from best to worst

Okay, I think now that we established I'm clearly not the expert of this episode, I think we can move on to the main part of this episode.

And maybe before we really deep dive into public transport, why don't you give us a quick recap of where we have left off? This is the final episode of the season.

So, Chris, where have we got to so far?

Yes.

So the deal was we picked apart the big three options for getting yourself around individually.

These definitely aren't the big three.

That's just the three that we've chosen from an emissions perspective.

First is electric cars.

So electric cars is an option.

Genuinely good.

And they're getting better every year as grids clean up.

Second, biofuels.

And this is like used cooking oils, algae, sometimes human poop.

They're useful in a few specific corners like logistics and shipping, but unlikely to scale to replace the family car, basically because you can't grow enough crops on the amount of land we've got.

to supply the need.

Thirdly, then there's hydrogen and this is mostly a red herring for anything that you personally drive, mostly because you lose so much energy in making it, compressing it, converting it back again into usable energy that a battery just does a better job.

So where hydrogen does make sense potentially is heavy stuff like steel, fertilizer, maybe shipping, but not your commute.

So that's like vehicles that you own sorted, if you like.

And way more detail on that in the episodes, the last three episodes that we've recorded.

And that's just a very brief summary.

Today, as we say, we're doing the last bit that isn't really about you owning anything at all.
