1/ I have mentioned stranded assets before; however, it is difficult to convey just how much chaos the green transition is going to cause to the world. From a purely technological angle, it is no different from any other "disruption" we've experienced in the past...
2/ ... were it not for the fact that oil has been a tool of realpolitik ever since it took over from coal. As I said when talking about stranded assets, it is incorrect to think that we can "transition" from a carbon economy to a renewable economy. It is not a "transition"...
3/... it will be a regime shift. Transition implies some from of smoothness in the function. I do not think there will be any smoothness. The carbon economy only works if the price of energy is very high and energy is scarce. Renewable energy will change the equation.
4/ At present we still rely on ~80% of carbon based energy to power the world. That seems like a lot, but it is dependent on several key factors: 1) continued investment 2) subsidies (implicit or explicit) 3) disregard for the environment. Lets see why these are all problematic.
5/ Oil is only priced as it is because we amortise cost over the lifetime of the investment. That is, built-in to the system, there is an implicit assumption that the exploration of the asset will be done over several decades. This is normally a fair assumption...
6/ ... until we suddenly have all models pointing to assets being worthless on a much shorter time horizon than expected. Lets say you decide to ban petrol cars in 2030. That does not impact oil assets in 2030, it impacts them right now because you need to adjust the demand curve
7/ It in effect tells you that assets that at present appear to be making money are suddenly losing money. It also tells you that spending any money whatsoever in oil (new investments) is a massively losing proposition because renewable assets will recover they cost much sooner.
8/ Subsidies are also another big problem. Oil is much cheaper than it should be because it is in the interest of governments to keep it as cheap as possible; expensive energy means expensive goods so it is normally a trade-off that favours "the economy". However...
9/ Renewable energy was developed with a fraction of the subsidies of carbon based energy forms. That is to to say: whilst people think that parity in cost of renewable versus non-renewable will make it "as attractive", it is not so because renewable energy...
10/ ... was developed with a fraction of the subsidies of carbon-based energy. The cost curve of renewables is an exponential; just look at solar. It may appear to be as cheap as gas or coal, but it is actually already far, far cheaper than them and its getting cheaper _faster_.
11/ Having to rely on virtually no subsidies - though the media will make you think otherwise - may have slowed renewables by a few decades; but, on the flip side, it meant that the resulting solutions are cost-wise in a different order of magnitude when compared to carbon.
12/ Finally the environment. Carbon based energy companies relied mainly on marketing to do their work with regards to the environment. That is to say, they did not spend the R&D budget needed to create actual clean solutions - if that was possible.
13/ They could afford to ignore the environment because the capital flows were still going towards them. Profit margins were healthy, and public opinion didn't care. However, with the recent shift towards green energy, this will mean capital markets will turn against them...
14/... at the worst possible time. Imagine having to pay more for your borrowings, to manage a portfolio of assets soon to be stranded, selling a product that people know is not a good idea and you see the conundrum.
15/ But remember: we still have 80% dependency on carbon; and for every basis point reduction, a massive disproportionate impact will be felt across the carbon industry, increasing the cost of energy *a lot*. And realpolitik amplifies this since countries will lose their leverage
16/ That is to say, the "transition" will be highly non-linear, and will almost certainly lead to crisis of the kind we had in the seventies - but with an effect many orders of magnitude bigger.
1/ One of the most peculiar things about Emacs is how you can spend ages (literally years) not using a feature - sometimes not even knowing about its existence - and then suddenly having your life change when you find it. org-mode agenda is one of those features.
2/ I've been using Emacs for time management for maybe a decade now, and I can honestly say I would not have made it through the PhD without it. Its such a long winded, uncertain effort over a long period of time that without some form of organisation I would have just got lost.
3/ Emacs has enabled me to keep close tabs on all the work carried out, to subdivide it as and when things change, with absolutely minimal fuss. I had been using things such as GitHub issues, Jira, etc etc for decades and always found them to be a pain. org-mode is just seamless.
1/ Another Friday, another Emacs thread. So, you've seen me ranting and raving about Emacs, and by now you may be asking: "So, are you telling me I should abandon X and use Emacs?" Sadly, the answer is almost always... "no, don't do that". But let me try to explain why.
2/ If you are a new-ish dev, you should try to optimise for two things simultaneously: a) things you find interesting *and* b) things that will make you employable. Therefore, you should use whatever environment and languages employers want. Sadly, that won't be Emacs (or Vim).
3/ Experienced devs end up converging to a productive workflow, adapted to a myriad of languages. In my 20 or so years of dev, I faced C, C++, VB, C#, Java, Kotlin, Ruby, Powershell, Bash, Python... Far too many languages to recount. Each had a preferred corporate dev environment
1/ Yet another thread on Emacs. One of the most important points in the life of an Emacs "user" (the quotes will become clear in a moment) is the moment where you realise that Emacs is not an editor but a framework to build editors, which happens to have a sample for you to try.
2/ I mean, most of us know this, but even then, its difficult to appreciate its logical consequences. Anyway, lets do a simple example for those not in the know. Say I start a project in VS Code, and create a new class. It prompts me to install extensions, and stuff happens...
3/ Then I go back to my class and if by magic, my environment is entirely configured to use C#. Now, as a regular developer I don't even bother distinguishing the different services the environment is giving me - I don't really care, all I care about is that my C# needs are met.
1/ Bem, sextou, e já à muito tempo que não faço um daqueles rants, de modo que tá na hora né. Hoje queria falar um pouco de energia, realpolitik e o futuro desse nosso laboratório de sobrevivência chamado Angola. Quem tá interessado, melhor pegar aquela cuca...
2/ Acho que até o mais desatento entre nós reparou nas várias e diversas notícias que têm aparecido sobre projectos de energias não renováveis em Angola. De repente, depois de muito tempo com tudo parado, agora parece está tudo em movimento.
3/ No contexto dos mercados financeiros, isto é bastante estranho: já é do conhecimento geral que nenhum pais desenvolvido vai fazer ou financiar projectos novos no campo das energias não renováveis. Há mesmo uma grande pressão para desinvestir, de todos os lados.
1/ Devo de começar por dizer que eu não sou um "saudosista" e que pouco - ou melhor, nada - conheci da Angola colonial. A independência para mim foi uma das nossas maiores vitórias alcançadas. Mas este post no Facebook mostra um lado interessante da nossa capacidade productiva.
2/ É importante comparar laranjas com laranjas: a economia colonial não era uma economia de mercado, o que significa que a viabilidade de muitos destes negocios não é fácil de aferir; seriam estas fábricas e fazendas produtivas apenas por usarem trabalhadores mal remunerados?
3/ Mas o que não se pode negar é que, comparando esta lista com o que foi feito desde 2002, não andámos muito para a frente desde o fim da guerra. E pior, se quisermos comparar alguém mais próximo temos só que ver o Rwanda (já nem falo do Botswana).
1/ After many years of thinking that hydrogen was a waste of time, it suddenly hit me: in the absence of a *major* breakthrough to allows us to create cheap batteries at will, hydrogen is going to be _the battery_.
2/ The growth of the solar and wind capacity will be much, much faster than the battery capacity and soon - as it always happens with capitalism - it will overshoot demand. Then it'll overshoot battery capacity. At that point you need to store energy by any means - even if lossy.
3/ That's where hydrogen comes in. It may be wildly inefficient when compared to lithium batteries, but if energy has a marginal cost close to zero, hey who cares? Better to store the energy in hydrogen than to throw it away.
