Didn't believe it at first so just reproduced it myself and this is indeed how wind and solar balance each other in OECD Europe according to the @IEA. Remarkable!
It means that increasing interconnectivity can be an alternative for seasonal storage for 100% renewable electricity.
I knew combining wind and sun lowers the cost and that there's more wind in winter. But this picture shows an almost *perfect* complementarity in the OECD region: wow.
And I know:
Monthly averages over a large area make renewables seem smoother than they are
We have a dunkelflaute now and then (sunless and windless weeks)
Transmission capacity over the OECD is far from perfect
But still extremely useful info!
Just for fun: the Netherlands with a logarithmic scale (because solar difference is pretty extreme summer-winter and because otherwise the early solar years disappear).
If you want to read research of ppl actually having detailed models (not simple graphs) of the entire world in 140 segments, clearly showing this complementarity with 100% renewables - and adding P2X + storage - I recommend the work of @ChristianOnRE.
Unpopular take: I've had enough of these "climate change is the end of the world and everybody who doesn't agree and panic is a moron" Hollywood movies.
I think they show Hollywood hyperbole is part of the problem, not the solution. grist.org/culture/dont-l…
I seldom fly, eat mostly vegan and drive electric from my solar panels of my energy positive house.
I've actually read the IPCC reports and I devote my life to developing models that show us how to accelerating the change towards renewable energy.
So I take this stuff seriously!
Climate change is a disaster and if we do nothing about it hundreds of thousands will die and many millions will be driven from their homes, every year for many many years.
But climate change is not a comet hurtling towards earth to doom us all.
Hydrogen is great! And most use cases pushed by the lobby are nonsense! Both these statements are true at the same time. And I love how @janrosenow has actually put in the time by collecting the independent (non lobby funded) studies on hydrogen.
In case you missed it: my friend (mostly ;-) @MLiebreich made what is probably the best hydrogen ladder detailing when it makes sense and when it doesn't. linkedin.com/pulse/clean-hy…
The problem for the hydrogen lobby (often fossil companies that want a conventional business model or a way to use natural gas) is that many applications that are sexy and great PR are actually not a great idea and the best applications for the planet are not commercial yet.
In my (Dutch) newspaper @trouw, mobility historian Vincent Vinne proclaims electric cars are unsustainable because they have lots of power and can drive fast.
Let me explain (again) why these things are actually beside the point for electric cars. trouw.nl/opinie/waarom-…
Basically it's very simple: regular combustion engines get less efficient when they don't perform at their optimal power number of rotations per minute. You can see this in a BSFC plot.
On this map optimum is >250 g/kWh but it can increase to 475 g/kwh. x-engineer.org/brake-specific…
So this means that a powerful engine (with a high top speed) is usually used at an optimal of say 70% of max power but only at 10% which then doubles energy use.
So historically speaking, mobility historian Vincent Vinnes is right. More power and topspeed is energy inefficient!
I think we need to start talking about psychological health of climate scientists. They are talking each other and us into a depression. Depression is real and it's a soul destroying unhelpful affliction to have.
Climate scientists are most severely impacted it seems. I think that's not because they know more but because they only focus on the problems (not on solutions) and because perversely they are more important when the problem is worse.
I've scanned hundreds of climate scientist papers the last few months and they almost always boil down to: "here's some new way to look at precisely how bad it is."
Even when you don't actually find that the future looks worse than you thought, that's a pretty horrible job.
I'm insanely proud that I have paved the way for PhDs like this in the NEONresearch.nl program.
First here is @swapnil_shekhar explaining in 2 minutes how he will research the diffusion of zero emission trucks and why that matters a lot.
Here the brilliant @EmielVanDruten (who is also a consultant for @WitteveenBos) explains how his PhD will shed light on how sector coupling can give us more renewable energy with less costly and labour intensive updates of the electricity grid.
Capitalism is not inherently bad. Many people just seem confused about income redistribution. I would love twitter to tell me why that is because I simply don't understand.
Quick🧵about how money could make use happier by redirecting it where it does the most good.
First of all, being super rich doesn't make you happy. That is not just the observation of this consultant to the super rich. theguardian.com/commentisfree/…
Extra money is super important when you are poor, but the added value per $ quickly decreases once you get richer and in US it tops at around $75k per year. cnbc.com/2015/12/14/mon…
