"Some 45% of total shipping demand is for transporting fossil fuels. That means some $42 billion per year is spent on fossil shipping fuels to transport other fossil fuels to their point of use." rmi.org/the-incredib...?
The Incredible Inefficiency of the Fossil Energy System - RMIrmi.org Over $4.6 trillion per year, almost 5% of global GDP and 40% of what we spend on energy, is wasted due to fossil inefficiency.

Is global tonne mileage not a stand in for "shipping demand"?

In my mind "shipping" is "transport by boat". Rystad makes the claim that it also includes transport also by trucks, pipes etc. But it could be transport by boat/sea fully dominates (?)

This talk from Saul Griffith goes through the proportion of waste, and what is left: youtu.be/1ewEaTlGz4s?... It's cued to his payoff. Back it up 15 min or so and the whole breakdown is in it. However, fossil fuel 'waste heat' etc is a subjective idea, b/c every source can be defined w/waste
Saul Griffith | The Energy Problem(s) - Following the Numbersyoutu.be Otherlab is a research and development firm focusing on renewable and clean energy, robotics, automation, digital fabrication, adaptive textiles, advanced manufacturing, and computational design tools. Similar to an accelerator/incubator, but with internally developed ideas, we nurture projects through the initial R&D phase, to forming entities within Otherlab, and eventually fundraising and spinning out into independently operating companies. In the past 5 years, Otherlab has collaborated with Stanford, MIT, Berkeley, Harvard, NASA, Autodesk, GE, Ford, Google, Motorola, IDEO, and a host of other universities and private research labs. Speaker Biography: Saul Griffith is the Founder / Principal Scientist at Other Lab, where he focuses his work on engineering solutions for energy production and energy efficiency. He has multiple degrees in materials science and mechanical engineering and completed his PhD in Programmable Assembly and Self Replicating machines at MIT. He is founderor co-founder of numerous companies, including Optiopia, Squid Labs, Potenco, Instructables.com, Howtoons and Makani Power. Saul has been awarded numerous awards for invention and was named a MacArthur Fellow in 2007. In 2011 Saul was named a World Economic Forum ‘Young Global Leader’. Saul holds multiple patents and patents pending in textiles, optics, nanotechnology, robotics, energy production, manufacturing and smart geometry. Saul co-authors ‘Howtoons’ with Nick and Ingrid Dragotta - a children’s comic book series about building your own science and engineering gadgets. Saul is a technical advisor to Make magazine and Popular Mechanics, and sits on various advisory boards including Duke Energy and the San Francisco 100% Renewable Energy Taskforce. He rarely wears shoes, is typically found knee-deep in machinery with fists full of tools, and has holes in most of his pockets.

For example, is every square meter of sunlight that doesn't have a panel under it 'waste'? The problem with fossil fuels isn't the waste heat, it's everything else.

btw, this description to me is like a stone in the shoe and a reminder of how dismal climate communications can be, tilting to the 'it's easy, it's cheaper, it's inevitable,' all of which are wrong, known to be wrong, and repeated endessly out of fear, which only makes the fear bigger. Thank you.

In the end I think of it as the EROI debate; you want as much useful energy out of as little as possible invested energy&resources, and with minimum externalised costs. On the other hand, putting a limit to the "wants" seem to be what is most incompatible with the current world order.

Bit like this one. bsky.app/profile/hako...
I liked this image (and the talk). 'Restraint' is a nice alternative word to 'sufficiency'. Concepts that the current system is very little eager to even consider.

Or how about: is every solar module placed so close to the ground that nothing living can grow underneath it “waste?” The argument here being that all energy landscapes should be shared land uses, not energy monocultures. We can learn from the way healthy forests cycle and recycle the sun’s energy.
