In den Niederlanden hat die Berufungsverhandlung begonnen, in der Shell gegen ein Urteil angeht, dass es zu einer drastischen CO2-Reduktion zwingt. Der wichtigste Gegner ist die Umweltorganisation Milieu defense. Shells Anwälte veranstalten eine propaganda-show, um die Verwendung fossiler Brennstoffe weiter zurechtfertigen. https://taz.de/Shell-vor-Gericht/!5999034/

Renewables and nuclear energy will dominate the growth of global electricity supply over the next three years, together meeting on average more than 90% of the additional demand
The IEA listing this in this quote is really helpful.

Around 40 million homes (or roughly 35 percent of all U.S. houses) use a gas stove to make food.
This is less than I thought it would be.

With Amazon the sole customer of the substation it will (via Oppidan) pay for the 26 month-long design and construction process, with the exception of the City-owned control building. It is expected to cost $5,388,260 across three payment milestones, one of which has already been paid.After it is built, property rights will transfer over to SVP, which will operate and maintain the substation.
OK. so it's not so much a substation owned like a block box.But Amazon is the sole customer, and it likely bought the site so :
a) it would stop others making a datacentre there b) it could then make use of the substation, and providing extra distribution for the other DCs it wants to operate and use so it can expand further

This verticalization will have the great flaw of making the real consumption of these infrastructures invisible. Today we can still retrieve some data from water and energy providers but when Amazon builds its own substations, like in Santa Clara, or Google its own pumping stations then the black box will continue to grow.
I had no idea Amazon is building its own substations.

At the environmental level, the territorial approach makes it possible to get out of the mystique of relative efficiency values to align consumption in absolute value with a local stock and a precise environment.
Absolutt comsumption as a percentage of the local resources would be a huge jump forward here

However, the possible unsustainability of the new data center project was outweighed by an $800 million project with various financial benefits to the community, so the construction project was voted 6-1 in the city council.
It's worth comparing this to other water reservations for context. Comparing it to agriculture in the same area might help, to see the choices people are facing
-
It also raises the point that data centers could crowd out renewable energy capacity on the grid, slowing down the country's energy transition.
I think the arguent made here is that the load can exceed the generation coming from renewable sources, meaning that this would end up leading to more dirty power coming online to meet the demand.
The alternative might be to adjust demand, with the virtual capacity curves proposed in the google paper,and supplemen that with storage
-
Energy used in a mine, in freight, in the supply and production chain is much less likely to be renewable.
It's worth considering things like how a CBAM a carbon border adjustment mechanism might affect this, as it's designed specifically to address this issue of high carbon intensity goods crossing country or trading block borders, like the EU

The US giant advertises that its data center in Eemshaven in the Netherlands would be 100% powered by RE since its opening in 2016. However, on Google's electricity supply matrices we can clearly see that 69% of the electricity supply was provided by RE. The remaining 31% is offset by RECs or virtual PPAs. Google's statement in the preamble is therefore not factually correct.
These might still be offset by RECs that are tied to a specific point in time, sometimes referred to as TEACS.

In this scientific literature, it is estimated that the manufacturing phase (construction of the building + manufacturing of the IT equipment) represents on average 15% of the energy and GHG footprint of a data center in a country with "medium" carbon electricity (approx. 150-200gCO2/kWh).. To get to this figure, it is assumed that the building is new and will last 20 years and that the IT equipment is replaced every 4 to 5 years. Based on GAFAM's Scopes 3, a recent publication by researchers from Facebook, Harvard and Arizona University estimated that the carbon impact of data centers related to IT equipment, construction and infrastructure was higher than imagined. There is therefore a growing interest in better understanding these "omissions".
This is a good point. Refresh rates can be closer to a 1-2 years in some hyperscalers. Good for use phase carbon, bad for embodied carbon

The Commission found that the arrangement, as currently written, could result in annual revenue shortfalls ranging in the millions of dollars, which other customers would have to cover due to the credits that could completely zero-out Facebook’s bill.“The Commission noted this is not logical— that a customer could reduce its bill by using more resources,” it said.
As I understand this, structuring this deal to give a a low cost for a loooong term agreement would mean bills would have to be raised on other rate payers to make sure the company with the monopoly is able to make the pre-agreed rate of return it as allowed to make each year.

After techUk’s Emma Fryer released the results of the second period of the UK data center sectors climate change agreement (CCA) 2nd Period findings in 2017, I conducted some desk-based research which looked at the issue from a UK PLC perspective and included all those enterprise data centers, server cupboards and machine rooms that are largely hidden.
John mentioned to me the the CCA notes from 2017 might be a little out. It's worth sanity checking that.
