The Weekend Wonk: New from Tony Seba – the Renewable Disruption

May 15, 2020

Are we entering the clean energy disruption?

If you have not seen Tony Seba, he’s what you would call a Techno optimist.
I always take a skeptical view, but it’s hard to dismiss him because
he’s been on the money for a number of years now.

If you have seen him, there’s a few new slides here, and I found it
worthwhile to review.
It will definitely cause you to see some things in a fresh way.


If your mind is not sufficiently blown, spend an extra 40 minutes on the video below.

    Shell cuts its dividend for the first time since the second world war. Oil prices turn negative in the US. Supertankers of unwanted fuel stack up in the Singapore Strait…

    => This oil crash is not like the others

  2. Sir Charles Says:

    What Is Shareholder Activism?

    A Timid Approach?

    What are shareholders demanding this year?

    => Here’s How Shareholders Are Pressuring Oil Companies to Act on Climate Change

    I’m buying this.

    I take Kurzweil, for example, with a much smaller pinch of salt than most people, and Seba’s line is basically the same: just follow the numbers.

    Never mind our instinctive refusal to take an exponential curve seriously. Never mind how it will happen. Happen it will.

    I think we’re heading for the biggest paradigm shift since the invention of the steam engine.

    Yep! Thanks.

    Needs 31,000,000 of those 2.5 megawatt wind turbines to meet ALL present human energy needs using a 30% Service Factor (amount of wind relative to the data-plate maximum output), 8% grid wiring heat loss & 20% I threw on to account for inefficiencies of making synthetic fuels for aircraft & rockets (I just threw in 20% to give some allowance for that). So at the 400-metre spacing that’s covering 4,960,000 km**2 of land & ocean, though the space between isn’t wasted of course. Would need to be considerably on land because 4,960,000 km**2 of ocean along 60,000 km of continent (which I’m guessing is ~all of it between 60S & 60N) would be a grid extending 82.7 km out from shore along the 60,000 km of shore with 207 wind turbines in each rank (so a ship leaving any continent would travel down a channel 400 metres wide between 2 ranks of 2.5 megawatt wind turbines with 207 wind turbines in each rank). So the ocean method would need a lot of electrical wiring.
