You expect me to deal with all the -5% waste sources in one article? Please explain me: what is the minimum share of total energy use that any activity should have before someone is allowed to dedicate any attention to…
Author here. Good point, and I wanted to add that this is the first article in a series about communal living.

"Learning and practicing how to correctly pull the trigger is probably the single biggest improvement to accuracy a new shooter can make." Thanks, I will change that sentence.
Happy to see that someone actually read the whole article before making a comment.

None of the laptops was brought to landfill, I still have them at home, which is why I could photograph them all. The malfunctioning charger was not the only problem. The Apple laptop had also gotten extremely slow.…
Author here. That sentence will be deleted when the website regenerates, cause it doesn't seem to have the effect that I was aiming for. Thanks for pointing it out. That said, I was impressed by the man's repair…
Now that I have some more time, I actually do want to address your comment in more detail. 1. "Kris De Decker just really doesn't like plastic!" Correct. We need to get rid of plastic. Keep reading me if you want to…
That's because you're living in a rich country where energy is cheap and abundant. That 40% of the global population that needs to walk for miles to charge their phone for a hefty price, or light their shelter with…
"If energy systems were installed that could heat and power these places without biofuel at all you'd be vastly better off. I did not see that point in there." What energy system you had in mind? Solar panels could…
A "central non-combustion power plant that doesn't emit air pollution or carbon"? What fuel is it running on?
Why would I repeat what is already written in the article?
They are not. For all the reasons mentioned in the article.
Depends on the stove. Tile stoves or masonry heaters can be +90% efficient. The same goes for inefficient stoves without a chimney, which is the majority of stoves in poor countries.
You seem not to realize that 40% of the global population IS ALREADY burning wood as their main source of household energy use. What is your alternative for them?
Maybe read the article before you comment? Here's the last two paragraphs: A thermoelectric heating system that runs on fossil fuels also compares favourably to a large cogeneration power plant, which captures the waste…
You have completely misunderstood the article. Try reading it again with an open mind.
Agreed that it's a one-time step decrease, and that the progress continues. But, why 2020? The panels that have powered the server were bought between 2015 and 2019, and who knows how long they had been in storage…
Calculating embodied energy based on costs is an option, but I have always learned that it's the last resort, as it has many problems, too. For example, How do you account for the fact that all production facilities for…
No, it's not just Spain. I only looked at European power grids, but their carbon intensity is all calculated in the same way.
A cost analysis remains to be done. But it's not as bad as it seems: we save $600 per year on hosting services.
The obsolescence of life cycle analyses is a topic in itself, and the lack of accessible data is a problem for anyone who tries to investigate high-tech products. For the solar powered website article, it's the order of…
The carbon intensity of the national grid is calculated as follows: carbon emissions of burning coal and gas in power plants (say 600 g/kWh) + carbon emissions of wind turbines, solar panels and the like (0 g/kWh).…
