The covid impact is an interesting example of demand reduction.
In my country the imact of petrol in road and air travel still being below pandemic levels in 2022 (latest data) is about 75TWh less fuel demand. This is almost as big as the output of all wind, solar hydro power gen in the country in energy terms (85 TWh) in 2022, and we’ve been investig fairly heavily for 2-3 decades now.
For cost effective . …
Drive less, drive (travel) more efficiently, live closer to the things you need.
Heat less, heat more efficiently. (I live in a cold country so cooling is not something i know much about - apart from it being a natural fit for distributed solar PV).
. . . probably also breed less on a global scale for the long term.
I think the pandemic proves that people can travel less if forced too, they just don’t want to, hence the bounce back we’ve been seeing.
But some structural improvements such as work from home for many office workers have locked in some benefits.
Some of the other solutions have complex feedbacks and infrastructure dependencies though. I don’t like utility scale PV as it competes with farmland or other land use like forests / swamps.
EVs and electrification of heat will ulimately double or triple the demand on our national electricity grid - i just can’t see renewable elec gen growing to that level even on a 30 year horizon .
We tend to do the easy and cheap projects first, so the next 300% is likely to be more than 3x as hard as the 100% so far. The exponential growth of the last few decades will plateau into an S-curve eventually. I think it already has for PV gen - which despite what this dude said in the videos, seems to need subsidy to drive uptake.
Maybe, unless we re-think hydro strategy
Eating the rich, of course.
Doctor Simon Clark? He has a phd!
What a clickbait thumbnail :/
I think this was a good video overall, though I do strongly disagree with his recommendation that trying to build a more just and fair world, i.e, degrowth or social revolution, right now, isn’t a good idea.
If anything, climate change is one of the most powerful things we have in our favor to make social change happen. To suggest we should tackle that part later, is just kicking the can down the road when there is less desire for rapid societal change.
If he thinks radical, systemic changes shouldn’t be attempted right now, that implies that he also thinks the necessary climate solutions are achievable within the existing system. What is basing that on? There is absolutely no reason to believe that the necessary solutions are possible within the existing systems, given that essentially all countries are well, WELL behind where they need to be to meet their own climate pledges.
