LLM-assisted coding - CO2 emissions.

2026-03-02 · 3 min read · AI LLM CO2 Emissions

Using a (local) LLM for an update emits 3.2x more \(CO_2\) than perfroming the update and refactoring by hand! In a previous analysis I have written how much time and energy had to be used to perform a LLM-assisted update of a simple C project to C++, with an introduction of Boost's program_options library. The TL;DR …

LLM assisted coding - a waste of energy?

2026-02-11 · 39 min read · LLM AI Energy

In this article I compare the time and energy cost required to update a simple old code used to generate entropy from a RTL SDR dongle from C to C++ by hand and using LLM-assisted coding (LLMAC). The addition of Boost's program options library is considered an extra and will prove to be an issue. The long-and-short of …

Estimation 1 - Validating our estimate

Validating the estimate Before proceeding with the next steps we shall validate our results to help calibrate the "gut feeling" required for estimates. The estimate of the peak power of balcony solar was fairly straightforward and does not require additional verification. The estimation of the capacity of a rooftop …

Estimation 1 - Rooftop solar

Rooftop solar estimate We want to compare this to the capacity were the panels mounted on the roof of the building. The shape of the building is somewhat similar to the following In the leading picture of this post we are looking at the buildings' upper left corner (1->3 direction). First we shall estimate the width …

Estimation 1 - Peak power estimation

Estimation 1 - Potential of balcony solar In the first instalment of the estimation blog we'll have a look at estimating the potential for solar panels installed on the balconies of the building depicted below Our aim is to estimate various quantities related to a solar installation for this building and we start with …

Estimation 1 - Error analysis

2026-01-07 · 2 min read · error analysis estimate solar

We have observed two very notable under-estimations: The width of the visible wall and therefore the effective width of the building \(w\) The length of the building \(l\) Since both factor into the calculation of the area of the rooftop our error is magnified quadratically. First we consider the error in the …
