It is highly inefficient.
Spend fuel to deliver the fuel from a place that uses that fuel to produce that fuel.
Compared to batteries and solar, which is basically once set up you just absorb energy from the sun and charge the batteries from anywhere with sun exposure to power vehicles.
by weight? by volume? by dollars?
Yeah, it seems provocative but it condenses too much and strips it entirely of its detail.
It is a good question however, how much oil is used moving oil?
Here’s the report Joshi is referencing.
I wish we’d link to this so we could actually discuss it instead of (or at least on top of) circulating a screenshot of a Bluesky post epically owning
the libsfossil fuels.
Edit: Here’s the 2022 UNCTAD report that the IRENA one cites.
The metric is “billions of ton-miles”, where a ton-mile is simply, unsurprisingly, a unit of transportation – a ton moved one mile.
Edit 2: Hang on, no, that assumption was faulty, looking at the graph again. The UNCTAD report’s graph only separates out gas and oil, so I have no idea what metric UNCTAD is using when they write:
Around 40 per cent of maritime cargo comprises fossil fuels, so the energy transition will alter the demand for shipping, as well as vessel types and sizes, and the fuels used by ports and ships. Sailing patterns and shipping networks will also need to be reorganized – as will the ports servicing such ships.
Edit 3: See below.
And this is the source that source references: https://qz.com/2113243/forty-percent-of-all-shipping-cargo-consists-of-fossil-fuels
It’s by weight (in the first paragraph). It also seems to include petrochemicals, though I don’t know how much that affects things.
Appreciate it. Quartz provides a link to UNCTAD’s data, but the link seems to be dead:
https://unctadstat.unctad.org/wds/TableViewer/tableView.aspx?ReportId=32363
Checking this out on the Wayback Machine, it’s a table titled “World seaborne trade by types of cargo and by group of economies”.
It’s significant regardless of which one of those it is.
The tanker in the picture makes me think it’s by ship.
tyranny of the trucking equation.
@MrNobody ähnlich verhält es sich mit dem Eigenverbrauch der RWE-Braunkohle-Tagebaue. Ich meine mich an eine Zahl von 25% oder 30% zu erinnern, die vom erzeugten Strom im benachbarten Kraftwerk direkt wieder von der gigantischen Maschinerie verbraucht werden…
Yeah, that’s not very typical. I’d like to make that point.
Takes money to make money, baby!
