How much power do hyperscalers use, and how much would it cost to go fossil-free 24 / 7 ?
I found out today that the Carbon Disclosure Project allows you to register and download their questionnaire responses. This means for companies that conveniently leave absolute energy usage figures out of their annual reporting, it’s possible to get an idea of what they might be – something I care about in the context of figuring…

A new Californian law on offsets goes a long way to making them more transparent
This came up on one of my feeds recently. Emphasis is mine from the original text on the Californian legislation website detailing the bill: AB 1305, Gabriel. Voluntary carbon market disclosures. This bill would require a business entity that is marketing or selling voluntary carbon offsets, as defined, within the state to disclose on the…

Listening notes: zero carbon cement on the Volts podcast
I listen to quite a few podcasts, and as an experiment in Jan 2024, I’m going to try to share the notes from ones that stand out for me. This is partly as a way to retain what I learn, and share with others, but get better at writing quickly. The first one is an…

Fixed broadband growth is slowing down
In my line of work, it’s common to see charts of ever growing internet usage, and projecting growth rates forward to reach eye-opening levels.

I’ve always been impressed by people who manage to get their annual “year in review” posts each year, and the first time in years, I think I might actually have a chance to get one written before the year closes. I don’t have long, so off I go…

I had no idea Nigeria had so much off grid energy
While doing some research for a coming episode of the Environment Variables, I ended up looking up information about Nigeria’s power grid – I knew grid coverage was patchy, but I had no idea, there was so much off site generation. Look at the map below, from the IEA page! Most of the time these…

Half formed idea: energy gravity and an energy gradient
I’m sharing this idea in half-baked form, because increasingly, when I think about electricity grid, I want to visualise it in this way to help understand the differences between various ways a power grid can be structured. If you think of energy has a gradient in the Z-axis where resources (as in generation) are peaks,…

How to have a Net Zero target whilst causing as much carbon pollution as possible
I was on a call for Carbon Tracker webinar call about a coming report, and a the subject of the most damaging way to do Net Zero came up. One speaker mentioned a a scenario that really stuck with me – he outlined a way you lets you say you have a Net zero target…

How clean does electricity need to get for the European ICT sector to half its emissions by 2030?
This post from John Booth from Carbon 3 about the recent coming European Energy efficiency directive, got me thinking about what kinds of changes are needed sector wise to meet their own targets by 2030. Here’s the good quote he draws attention to in his post: ‘The ICT sector is another important sector which receives…
