And yet the net result super bad: 256g/kWh to 500g/kWh. Gas is absolutely not “low emissions”. It’s actually the second worst offender after coal (400gCO2eq/kWh vs 1000 for coal).

And yet at this very moment, Germany is 10x the CO2 output of France (36g vs 390g), after spending 500 billion euros.

It actually shows live output and total capacity. Solar capacity is listed at 52GW. Wind total capacity is 61 GW, with an mediocre 15% output. That’s not a lot to show for 500 billion euros...

Settles a lot of arguments and removes a lot of BS and preconceived opinions when talking about energy. Case in point: look at France vs Germany (who has now spent 500 billion euros in renewables). Now imagine if that money had been spent e

Look at the energy sources to understand why. France: Nuclear Norway: Hydro Sweden: Hydro + Nuclear That’s why nuclear in making a comeback in the mind of those who care about climate change.

This is not a subsidy but a loan. If the state wants to stay out of it, but only has to say: "we are going to be using nuclear power for the next 40 years", and the interests will naturally go down because the investment is safer,

Most of the cost of a MWh of nuclear comes from the cost of capital (interests). [1] Put differently, if capital is backed by the state, that the $/MWh could be a _lot_ less than it is. 1. https://imgur.com/a/4mAlU

Comparing a source controllable uninterrupted source of energy with an unreliable intermittent one doesn't make sense. Having power when you need it is very valuable. And in the case of renewables, you'd need to account for storag

Bazel is in Java...

From the bazel releases. It always starts with a binary.

Then how much harm? How many cancers?

by steeve 6y ago
How many deaths for Chernobyl, Three Mile Island and Fukushima? Would that number change your mind?

Wind and solar are very diffuse forms of energy, so harvesting them is hard and costly both in money, and most importantly for the biosphere. For instance, the universe radiates 3K of heat, which we could harvest and use. We don't beca

A few hints: - read about CIGEO - nuclear waste, once it has decayed, becomes metal in glass - nuclear waste is _small_, see [1], the nuclear fuel waste is the tiny red cube. - wind turbines have a 20 years lifespan, after which the blades

Had to build bazel from scratch, you need: - a previous version of Bazel - GCC/Clang - JDK - Python - Zip and Unzip Not sure I'd call that "huge". Perhaps the JDK?
258.
by steeve 6y ago
That's up to you. Bazel can fetch and build core from wherever: local or remote. Also, when fetching from git, it will high encourage you to use commits instead of tags, or when downloading archives from http, use a sha256. Actually it

I'm glad to see this. What people first and foremost forget is Bazel is a package manager/overlay in itself (and a very good one too), which allows for very complex (and yet safe and reproducible) builds. The learning curve is ste

This comment. UK's CO2 _emissions_ may have fallen to 1890's levels, but CO2 _consumption_ hasn't: 89% of 1990 levels according to [1]. Let's not pat ourselves on the back and pretend the problem is solved. 1. https:&#x

You are right. The actual number for a nuclear reactor is 13 140 000 MWh. (1000MW * 18 months). But I figure people would get the idea better.
262.
by steeve 6y ago
5000 tons at 1500m is ~20MWh [1], assuming 100% efficiency (frictionless free fall). That means that the theoretical maximum is 50x (!) less than 1 nuclear reactor can do in 1 hour (1000 MW for 18 months or 13 140 000 MWh). Put it different

The title is deceptive, to say the least.

It does, via https://github.com/bazelbuild/rules_foreign_cc , but it's not always the best idea.

It is focused on producing static (or mostly static) binaries. Obviously not everything can be in the sandbox, but in the Bazel world, it takes over the build of all your dependencies (as it is also a package overlay).

by steeve 6y ago
+1 for Bazel. It is most importantly a language independent package overlay. To put it simply, it pretty solves the package/module issues for C++, as well as cross compilation etc... It's beautiful.

Cool article! Small note: you can use rules_go's builtin go_embed_data [1] rule instead of rolling out your own using genrule. 1. https://github.com/bazelbuild/rules_go/blob/master/go/extras...

This has been demonstrated to be false at the Europe scale, unfortunately. See https://youtu.be/1aCHN6dytVY (in french though) In a nutshell, either there's wind everywhere, or not.
