Another framework for implementing custom scheduling poli-cies without direct kernel modification is Meta’ssched_ext.sched_extis a Linux kernel patch that proposes a new abstract schedulerclass, which can be instantiated with scheduling programs in eBPFat runtime. There are ongoing discussion of upstreamingsched_extinto Linux. We have chosen to implement the scheduling poli-cies proposed in this paper with ghOSt, but it is also possible toimplement them withsched_ext

He added that private companies, which will have a significant role in the transition, want to see policy certainty enhanced in the months ahead. The group is awaiting the finalisation of the Electricity Regulation Amendment Bill, which promises to open up the electricity market and put an end to Eskom’s longstanding monopoly, and the Integrated Resource Plan.

consumes 19% less energy per event in high performance mode

%. This shows, that the impact of load shaping heavily depends on the power proportionality53 of the underlying hardware, and that it is not a reasonable measure per se.

Although solar forecasts are not very promising this time, it again permits to discharge to 30%, as the carbon intensity during the next day is expected to be especially low. Instead of drawing carbon-intensive grid energy at night, the demand is thereby shifted to the next morning where the batteries are charged to 60% using cleaner energy.

Although the carbon-aware experiment uses 2.4 % more energy than the baseline (which is because not all power modes have the same energy-efficiency), its associated carbon emissions through grid power consumption are 35.9 % lower. In the following, we will briefly analyze the two experiments and to demonstrate how our integration enables research and development of carbon-aware applications.

The control unit adaptively adjusts the battery's minimum state of charge and grid charge rate over time. In particular, in case of promising forecasts for solar power production or low carbon intensity, it is able to temporarily deplete the battery to 30%.

This is especially the case when not testing virtualized applications on powerful hardware but embedded systems that often only run only one energy-hungry process at a time. In these systems, load shaping is likely rather performed on a device level, for example, through DVFS.

Therefore, if applications under test are deployed on physical nodes like single-board computers, it is recommended to use dedicated hardware for measuring the power usage of these devices. For example, in our experimental testbed we monitor the current and voltage of a RaspberryPi 4b with a USB to USB measuring device equipped with an INA219 DC current sensor.

Note: The physical node's power usage is controlled via DVFS, while the virtual node uses rate limiting on the executed process.

“These claims assume that a company that pollutes more now should be able to pollute into the future. This means Global North companies will continue to inequitably dominate use of our remaining carbon budget. These findings should raise real questions for any bodies that claim to set standards for voluntary corporate climate targets,” David Tong, Global Industry Campaign Manager for Oil Change International, said.

A major blindspot is the fact that SBTi does not take into account new companies with their share of emissions coming into existence in the future. In SBTi’s framework, existing companies are allocated a share of the carbon budget without leaving any room for new players, some of whom might be more efficient or even working in the decarbonisation space like solar technologies. This further entrenches fossil fuel developments by existing companies and also raises questions about equity.

Net-zero corporate pledges are voluntary, which means they can be reeled back in as quickly as they are announced.Shell scrapped its emission reduction target for 2035 when it sought to grow its gas business, for example, and BP walked back on some of its climate commitments when profits hit a record high. An Oil Change International assessment of the climate plans of eight oil majors—Chevron, ExxonMobil, Shell, TotalEnergies, BP, Eni, Equinor, and ConocoPhillips—released this year found that all eight continue to drive fossil fuel expansion and six have explicit goals to grow their total production volume this decade

Not all do so and there is no agreement on what a fair share is, but by claiming an individual target is Paris compliant is implicitly making an ethical claim that this represents your fair share of the global response, without saying how it is fair,” she said.

The Climate Policy paper points to issues that arise when individual countries or companies link their efforts to mitigate climate change to Paris Agreement goals. If such linking is indeed necessary, the authors say that assumptions about time scale, spatial scale and equity must be included in the analysis and presented transparently.The paper is “a welcome contribution” because it asks countries to center mitigation claims in a context of national contributions to global fair shares of the climate response, said Kate Dooley, a research fellow in the School of Geography, Earth and Atmospheric Sciences at the University of Melbourne. At present, many wealthy countries have exceeded their fair share of the carbon budget.

The distribution of emissions over time is not just a question of cumulative global emissions—it’s also a matter of equity. Rich, industrialized countries have already claimed a disproportionate share of the carbon budget that has brought us to around 1.2°C warming today. The U.S. has emitted about 25 percent of cumulative emissions; Europe, meanwhile, has emitted around 20 percent.

In fact, capturing CO2 from ethanol production is so easy that ethanol production is the biggest source of purified CO2 in the US, and the second biggest source in Europe. This is where we source the CO2 that we use in fizzy drinks, food production, fire extinguishers, etc.

it did so by taking some short cuts. Android itself was an acquisition in 2005 (for $50 million, with a keyboard interface) and, in response to the iPhone, a new touch user interface was developed

In their annual financial report, companies will have to disclose sustainability information in the management report. The details of the sustainability information to be published are set out in Commission Delegated Regulation (EU) 2023/2772 of 31 July 2023, to which the French Decree 2023-1394

That’s no small task: In 2022, SAP spent approximately €7.2 billion in purchases from more than 13,000 suppliers worldwide, its annual report shows; 30% of that being on cloud services – more on that below.

He is referring to a mechanism SAP first tested in 2016 across 10 countries. This prices CO2 (from €40 to €400 per ton; depending on the flight and its distance) to release money for sustainability initiatives, as SAP ramps up not just its own internal decarbonisation programme (it aims to reach net zero by 2030) but continues to build out a suite of sustainability products for its expansive customer base.

As 45% of last year’s record solar additions were distributed generation, the exclusion of small solar installations is affecting these numbers a lot more than it used to.

If there was one universal piece of advice I had for marketers seeking to broadly improve their organic search rankings and traffic, it would be: “Build a notable, popular, well-recognized brand in your space

A module on “Good Quality Travel Sites” would lead reasonable readers to conclude that a whitelist exists for Google in the travel sector (unclear if this is exclusively for Google’s “Travel” search tab, or web search more broadly). References in several places to flags for “isCovidLocalAuthority” and “isElectionAuthority” further suggests that Google is whitelisting particular domains that are appropriate to show for highly controversial of potentially problematic queries. 

Our study suggests the transformation pathway will have three main phases.

Meanwhile, gas does not play a significant role in the power sector in our scenarios, as solar and wind can provide cheaper electricity while existing coal power plants

The upper panel in the figure shows the installed capacity of coal power plants and the lower panel their electricity production from 2021 to 2060.

What is happening in China with electric vehicles is pretty stunning. China is the world’s largest auto market by far — in 2022 China sold 26.8 million vehicles, the U.S. sold 13.8 million and Japan was third with 4.3 million.

There is mounting evidence that the demand for imported cooking oil in the UK and Europe is being met with virgin palm oil that has been fraudulently passed off as waste. This would cancel out the fuel’s emissions savings, due to the land clearances for oil palm plantations.

To produce the 12,750 MWh that will be generated by the data center at full capacity, 2660 t of pellets would have to be burned per year

Instead of wasting the 45°C hot air from equipment and servers in the atmosphere, the new data center will inject this flow into air-to-water heat pumps; these will raise the temperature from 45°C to 67-82°C in order to adapt to the current requirements of the district heating installations of Services Industriels de Genève (SIG).

First, it will require the operators of regional grids across the country to forecast their region’s transmission needs a full 20 years into the future, develop plans that take those forecasts into account, and update those plans every five years. In practice, this should mean a more robust consideration of new wind and solar options, as well as greater adherence to the net-zero emissions targets set by many U.S. states.

Over the past three years, battery storage capacity on the nation’s grids has grown tenfold, to 16,000 megawatts. This year, it is expected to nearly double again, with the biggest growth in Texas, California and Arizona.

The critical sixth key was the contest key: Bernie Sanders’s contest against Clinton. It was an open seat so you lost the incumbency key. The Democrats had done poorly in 2014 so you lost that key. There was no big domestic accomplishment following the Affordable Care Act in the previous term, and no big foreign policy splashy success following the killing of Bin Laden in the first term, so there were

Now, the United Nations has taken a first step toward filling in these data gaps with the latest installment of its periodic report on e-waste around the world. Released last month, the new Global E-Waste Monitor shows the staggering scale of the e-waste crisis, which reached a new record in 2022 when the world threw out 62 million metric tons of electronics. And for the first time, the report includes a detailed breakdown of the metals present in our electronic garbage, and how often they are being recycled.

Following an attributional approach, and with the assumptions retained, the Iroco study evaluates the greenhouse gas emissions attributable to one week's use of a mailbox at 63.2 gCO2eq.

However, corporate governance in the telecoms sector is notconducive to the kind of radical decisions that separationrequires. Decision makers and boards are incentivised onmetrics that require short term continuity, not disruption

Rural broadband in Europe is increasingly deployed in aneutral host model with a single fibre networkconnecting homes and multiple service providersdelivering services over that network.

as pure infrastructure players borrow atlower rates and expect lower returns, they will deployinfrastructure where vertically integrated players won’t,and with no (or less) public subsidies;

We have one leading example of voluntary structural separationresulting in increased valuation of the separated entities -Telecom NZ, in 2011. Post de-merger, after years of flat marketvaluation, both Chorus (infrastructure) and Spark (services) sawshare prices rise. Between 2015 and 2023, the combined market1 Tower companies (or towercos) are infrastructure companies that managemobile towers for multiple mobile network operators.capitalisation of Chorus and Spark grew by 150%, whereas thatof European and US vertically integrated telcos2 grew only by15%.The plan also delivered full FTTH coverage to 87% of NewZealand homes with 72% adoption.

So should we collectively accept a radical shift in our policy and regulatory framework in order to ensure that the beacon of the European economy can deploy infrastructure that Sweden, Denmark, Spain, France, and many of the smaller European countries started successfully deploying long ago? This, in a nutshell, is why the Commission never talks about Germany.

The article confirms many of my suspicions — that, as The Information wrote, "other software companies that have touted generative AI as a boon to enterprises are still waiting for revenue to emerge," citing the example of professional services firm KPMG buying 47,000 subscriptions to Microsoft's co-pilot AI "at a significant discount on Copilot's $30 per seat per month sticker price." Confusingly, KPMG bought these subscriptions despite not having gauged how much value its employees actually get out of the software, but rather to "be familiar with any AI-related questions its customers might have."

It's important to understand these complexities because they are currently being flattened not just by corrupt government officials in Global South countries or fossil fuel executives in Texas, but also by a whole ecosystem of pundits like Jordan Peterson, Michael Shellenberger, Alex Epstein and even Joe Rogan, who use the idea that fossil fuel development will solve poverty in Africa as justification for continuing fossil fuel's dominance in the world. In fact, fossil fuel development hasn't even solved energy poverty in the African countries that have embraced it; Nigeria has the continent's largest and oldest fossil fuel industry and yet still has the world's lowest energy access rates.

To plug the financing hole Intel has had to rely on a wide variety of capital sources to fund everything: traditional debt financing, government support, and even more creative financial engineering schemes like the Brookfield fab deal to find a way to pay for everything.

As noted by researchers at the University of Oxford and the Mercator Research Institute on Global Commons and Climate Change, carbon-intensive sectors like electricity generation actually contribute relatively little to the world economy, compared to high-value but lower-emitting sectors like IT, real estate, and social work. 

The above report is an underestimation of datacenter power demand, but there are plenty of overestimates too

The FTC, of which Khan is now chair, contends that Amazon has found a way to push up prices after all, without losing shoppers. It does this, the FTC argues, by imposing ever-higher fees on third-party sellers, who have no choice but to pass these costs on to shoppers by raising their prices. If those businesses try to sell more cheaply elsewhere, Amazon throttles their sales on its platform—which, thanks to the central place in e-commerce that Amazon has built up over the years, can be a death sentence for these businesses. So, according to the FTC, sellers generally absorb the high fees by inflating their prices not just on Amazon but across the web—precluding the price competition that could loosen Amazon’s grip on e-commerce.

Because we use systemd for most of our service management, these stdout/stderr streams are generally piped into systemd-journald which handles the local machine logs. With its RateLimitBurst and RateLimitInterval configurations, this gives us a simple knob to control the output of any given service on a machine. This has given our logging pipeline the colloquial name of the “journal pipeline”, however as we will see, our pipeline has expanded far beyond just journald logs.

Overall, Iceland produces approximately 20 terawatt hours of electricity per year.

Landsvirkjun built Kárahnjúkar despite protests, it started operating in 2009. But the controversy changed Iceland's energy policy. A fourth aluminium smelter was never finished, and in an announcement made in 2022, Landsvirkjun writes that it "will for the time being not focus on attracting new large-scale customers in the metal industry or other industrial commodities."

Meta previously bet on CPUs and its own in-house chips to handle both traditional workloads and AI ones. But as AI usage boomed, CPUs have been unable to keep up, while Meta's chip effort initially fizzled.

It’s past time for the IT and BPO Services industry to jump to a new S-curve driven by technology arbitrage if they wish to get back to another season of hockey stick growth:

wrote about this in 2012 in a book called Liars and Outliers. I wrote about four systems for enabling trust: our innate morals, concern about our reputations, the laws we live under, and security technologies that constrain our behavior. I wrote about how the first two are more informal than the last two. And how the last two scale better, and allow for larger and more complex societies. They enable cooperation amongst strangers.

They were national strategic programs. The strategic programs were aligned with nuclear weapons programs. The government picked and enforced a single design for all of the reactors. The reactors were GW-scale due to thermal efficiencies required for cost effectiveness. The government ran human resourcing. The programs ran for 20 or 30 years. They built dozens of nuclear reactors to maintain the teams and momentum and to share lessons learned.

A key point to remember about the US DOE is that 55% of its budget is related to commercial nuclear generation. The other 45% covers dams, geothermal, wind, solar, tidal, wave, biomass and biofuel energy.

A second MoU on gas export partnership was agreed between Riverside LNG of Nigeria and Germany's Johannes Schuetze Energy Import AG. Under the accord, Nigeria will supply 850,000 tons of natural gas to Germany annually which is expected to rise to 1.2 million. The first deliveries will be in 2026, Ngelale said.The deal will help process about 50 million cubic feet per day of natural gas that otherwise would have flared.

Volkswagen teamed up with ClimatePartner GmbH to generate offsets so it can be “independent from the market where you can’t control what’s effective and what’s not,” said Esra Aydin, a spokesperson for the automaker. But the credits didn’t materialize in time last year and it ended up going back to the voluntary market where cheap renewable-energy credits were the only ones that worked with its budget.

In other words, the companies decided some offsets weren’t good enough to meet their own climate goals — and yet have continued selling them to customers as a feel-good solution.

In contrast with the precipitous fallings-off of platforms like Myspace and LiveJournal, the decays of which have been clear and irreversible, Tumblr has kept defying expectations and stayed somewhat thriving against all odds. That is, in part, thanks to the guidance and guardianship of Automattic, which acquired Tumblr for the bargain-bin price of $3 million.

The two corporations aren’t directly buying fuel from World Energy. Instead, they’ll purchase certificates representing SAF that gets pumped into the larger supply chain — then count the associated carbon reductions toward their sustainability goals. Microsoft agreed to buy certificates representing 43.7 million gallons of SAF over a 10-year period, while DHL signed a contract for 177 million gallons over seven years.

Provided that reliability and supply improve, the grid could become the optimal solution to provide almost 60% of people with access to electricity in each scenario.In the AC, Nigeria achieves universal access by stepping up efforts to provide off-grid solutions to those populations that live far from a grid.

However, some have criticised the CIPP for providing market-rate loans rather than special financing schemes, which will lead to high costs for Indonesia and could deter other countries from accepting similar deals in the future. 

Here’s another problem: from 2020 to 2022, shopify claims around 31,000 tonnes of carbon removal. But according to the CDR.FYI database, only 4,000 of the tonnes they have purchased have been actually physically removed from the atmosphere

Shopify don’t count the emissions footprint of the products sold by merchants in their actual climate data. No shipping, no manufacturing emissions, nothing (Amazon play a similar trick).

It spent just over $5m to advertise its compact Bolt option over the same time period. Ford spent $61.2m (£48.7m) to advertise its electric F150 , and around $9m to advertise its mid-size electric Mustang. Among the top automotive advertisers, only BMW and Hyundai are spending as much or more to market their more efficient EVs.

The CDP, previously known as the Carbon Disclosure Project and the most comprehensive global registry of corporate carbon emission commitments, recently said that of the 19,000 companies with registered plans on its platform, only 81 were credible.

Over a year that equates to roughly seven million in savings and is precisely why the biggest names in tech are moving to colder, more remote locations.

CSP makes it possible for server administrators to reduce or eliminate the vectors by which XSS can occur by specifying the domains that the browser should consider to be valid sources of executable scripts. A CSP compatible browser will then only execute scripts loaded in source files received from those allowed domains, ignoring all other scripts (including inline scripts and event-handling HTML attributes).

The approximate cause of power problems often isn’t that hard to find. Fixing them is often the hard part. Good luck.

Intel processors also support multiple P-states. P0 is the state where the processor is operating at maximum frequency and voltage, and higher-numbered P-states operate at a lower frequency and voltage to reduce power consumption. Processors can have dozens of P-states, but the transitions are controlled by the hardware and OS and so P-states are of less interest to application developers than C-states.

Intel processors have aggressive power-saving features. The first is the ability to switch frequently (thousands of times per second) between active and idle states, and there are actually several different kinds of idle states. These different states are called C-states. C0 is the active/busy state, where instructions are being executed. The other states have higher numbers and reflect increasing deeper idle states. The deeper an idle state is, the less power it uses, but the longer it takes to wake up from.

Even before Hardin’s ‘The Tragedy of the Commons’ was published, however, the young political scientist Elinor Ostrom had proven him wrong. While Hardin speculated that the tragedy of the commons could be avoided only through total privatisation or total government control, Ostrom had witnessed groundwater users near her native Los Angeles hammer out a system for sharing their coveted resource. Over the next several decades, as a professor at Indiana University Bloomington, she studied collaborative management systems developed by cattle herders in Switzerland, forest dwellers in Japan, and irrigators in the Philippines. These communities had found ways of both preserving a shared resource – pasture, trees, water – and providing their members with a living. Some had been deftly avoiding the tragedy of the commons for centuries; Ostrom was simply one of the first scientists to pay close attention to their traditions, and analyse how and why they worked.

The features of successful systems, Ostrom and her colleagues found, include clear boundaries (the ‘community’ doing the managing must be well-defined); reliable monitoring of the shared resource; a reasonable balance of costs and benefits for participants; a predictable process for the fast and fair resolution of conflicts; an escalating series of punishments for cheaters; and good relationships between the community and other layers of authority, from household heads to international institutions.

Among his proposed solutions to the tragedy of the commons was coercive population control: ‘Freedom to breed is intolerable,’ he wrote in his 1968 essay, and should be countered with ‘mutual coercion, mutually agreed upon’. He feared not only runaway human population growth but the runaway growth of certain populations. What if, he asked in his essay, a religion, race or class ‘adopts overbreeding as a policy to secure its own aggrandisement’? Several years after the publication of ‘The Tragedy of the Commons’, he discouraged the provision of food aid to poorer countries: ‘The less provident and less able will multiply at the expense of the abler and more provident, bringing eventual ruin upon all who share in the commons,’ he predicted. He compared wealthy nations to lifeboats that couldn’t accept more passengers without sinking.

Mobile network operators, often government sanctioned monopolies granted via spectrum licenses, are in increasing competition with an explosion of “open spectrum” technologies and new operating models for wireless networks.

there are well understood risks of turning unchaperoned engineers loose on social problems

there are well understood risks of turning unchaperoned engineers loose on social problems. And more so as the engineering tools become more specialized: if your only tool is an abstract algebraic curve, all the world becomes a cryptographic nail. 

This liminal space, often vaguely described as the “Internet of Things” (IoT) doesn’t hold much resemblance to the Internet, at least as originally conceived. And the “things” commonly encountered are toasters, washing machines, and toothbrushes, with an often inexplicable desire to “connect.”

IoT’s current failures are also an opportunity. Beyond the absurdity of overly chatty microwaves, plugging the physical world directly into extractive (and often tenuous) business models has raised public awareness of the shortcomings of how we currently build digital infrastructure. Whether it’s a bike that stops working when its manufacturer goes bankrupt, or a home appliance with unclear allegiances, it has created real harms from exfiltration of personal data, and unnecessarily reducing the lifespan or increasing fragility of devices we depend on as part of daily life.

For an example of an unintended consequence, let’s say the result of your optimization project is spare capacity at a cloud provider. Then that capacity is then offered on the spot market, which lowers the spot price, and someone uses those instances for a CPU intensive workload like crypto or AI training, which they only run when the cost is very low. The end result is that capacity could end up using more power than when your were leaving it idle, and the net consequence is an increase in carbon emissions for that cloud region.

Average retail electricity rates in Hawaiian Electric territory are higher today than they were a decade ago, per state data. Kauai’s rates have dropped from the highest in the state to the lowest, as KIUC shifted from costly imported fossil fuels to cheaper solar generation.

but also depend on a global renewable energy production whose capacity cannot exceed 30% globally (EIA),

It should be noted that in France, regulations do not allow this market-based approach when reporting company level CO2e emissions : “The assessment of the impact of electricity consumption in the GHG emissions report is carried out on the basis of the average emission factor of the electrical network (…) The use of any other factor is prohibited. There is therefore no discrimination by [electricity] supplier to be established when collecting the data.” (Regulatory method V5-BEGES decree).

In the end, there was an undisclosed settlement between Verizon and Mozilla, but ComputerWorld later reported that financial records showed a $338 million payment from Verizon in 2019. On top of revenue-sharing with Google, that payment drove up Mozilla's revenue, which in 2019 reflected "an 84 percent year-over-year increase" that was "easily the most the open source developer has booked in a single year, beating the existing record by more than a quarter of billion dollars," ComputerWorld reported. Perhaps that bonus payment made switching back to Google even more attractive at a time when Baker told the court she "felt strongly that Yahoo was not delivering the search experience we needed and had contracted for."

Finally, over a longer time frame, novel technologies could drastically lower battery-related mineral demand for nickel and copper in particular, but the mineral intensity of next-generation battery chemistries remains uncertain and could even increase demand for some battery minerals. For example, solid-state battery chemistries could increase lithium demand by up to 28%.11

Figure 1. Comparison of ore extraction in IEA NZE scenario and sensitivity of substantially improved recycling and potential ore grade decline

Ore extraction is largest for EVs, growing 55 times from 2021, compared to 13 and 9 times for solar PV and wind power, respectively

This means that the high demand for minerals through the energy transition is of a (temporary) stock building nature, while fossil-related extraction is continuous and dissipative. In the longer term, the decommissioning of end-of-life renewable generation provides opportunities for reuse or recycling. This can mitigate demand of primary produced minerals for new renewable installations

For starters, if you are seeking to use a green financial instrument to finance your data construction project anywhere in the world, and have European investors, then the Taxonomy Climate Delegated Act (TCDA) will apply. This requires the operator to implement 106 of the EU Code of Conduct for Data Centre (Energy Efficiency) best practices as well as undertake various other activities

While it is capable of providing constant power, hydrogen fuel cells are also being considered for providing backup power to data centers. This is greatly appealing to data center operators as a more environment-friendly replacement for traditional diesel generators. This change would see the use of fast-start fuel cells, such as proton exchange membrane (PEM) fuel cells which could take the place of diesel generators.

The key benefit and primary motivation for installing hydrogen fuel cells within a data center is to reduce carbon emissions. As stated, some fuel cells, such as SOFCs, can use natural gas. While it is less damaging to the environment than diesel, it still results in significant carbon emissions.

SOFCs and PEM fuel cells differ from one another in their construction, materials, and operation. In a high-level view, the primary differences are the electrolyte materials (where the hydrogen and oxygen react) and operating temperatures. SOFCs operate at high temperatures, requiring longer start-up times and as a result, only being suitable for continuous power supply. PEMs, by contrast, operate at lower temperatures and are capable of fast-start or continuous operation, but are a more expensive option.

The majority of fuel cells currently in use in data centers are solid oxide fuel cells (SOFCs), providing constant power. SOFCs can generate power through the conversion of fuels such as natural gas and biogas, into hydrogen, which is then reacted in the fuel cell to generate power. While using natural gas still results in carbon emissions, SOFCs are able to generate power with higher efficiency than combustion engines. SOFCs can also be fuelled directly with hydrogen, although this is not the norm due to hydrogen’s cost and availability.

decade ago, these plants provided “low carbon” electricity in comparison to the grid at the time, but now in many cases, emit more carbon than local grids. Countries that already have decarbonized grids, France, Sweden, and Scotland, for example, will not benefit from a continuous system that uses natural gas to begin with.

One suggestion is for greater integration of energy systems, which would see data centers located adjacent to energy industries or having data centers integrated with hydrogen-generating plants and fuel cells. This solution sidesteps planning problems by locating data centers alongside low-carbon energy industries. A major issue with this (aside from the available land) is blurring the lines between the data center operators, utility providers, and energy companies.

From a mechanical perspective, designing a hydrogen storage system is significantly more complex than a diesel storage system. Hydrogen has more storage options available however, it presents higher risks than diesel such as greater flammability and explosivity, higher pressures, potential for low temperature, or chemical storage methods which are all hazardous. This therefore requires the mechanical design for such a system to comply with rigorous safety standards.

Google has argued that switching search engines is just a click away and that people use Google because it's the superior search engine. Google also argued at trial that Microsoft's failures with Bing are "a direct result of Microsoft’s missteps in Internet search."

Provide a transitional implementation for network operators and protocols that do not yet support standards-based Layer 2-3

Despite the unknowns, the technology definitely piques the interest of owners and operators of data center facilities, with analyst firm Omdia noting that more than 80 percent of survey respondents will most likely deploy grid-interactive UPSs within the next five years. As usual for this industry, the technology will require more deployments and for it to mature before it becomes the standard way data centers and other mission-critical facilities will be built.

While exact numbers are not disclosed, such as battery capacity and how much Microsoft is willing to make available for grid interactivity, the company claims that, over the next couple of years, this move will remove about two million metric tons of carbon dioxide emissions that would otherwise be generated from Ireland’s National Grid.

Let’s just pause to emphasise this point: no amount of R&D, innovation or technology will allow us to remove CO2 from the atmosphere without spending at least 191 kWh per tonne of CO2.

It should be noted that the third normative approach considers the global need for electricity asoutlined by the International Energy Agency (IEA) for different scenarios and develops an interim1.5DS within which ICT should not expand its current share of electricity. This electricity budgetuses the IEA trajectories for a 2°C scenario (2DS) and a below 2°C scenario (B2DS) to derive a 1.5°Ctrajectory for world electricity usage through doubling the difference between them and subtractingit from the 2DS as described in [IEA ETP]. This is an interim approach as IEA has not yet establisheda 1.5DS. The budget is then used to determine the amount of electricity that could be used by thesector if keeping its share at the current level. As the IEA is planning to include a specific 1.5DS, thetrajectories will be reviewed when the new IEA scenarios are published.

The VIC system created maintains a list of available URLs or DNS entries for the service requiring computation, each of which live in a different datacenter in a different part of the world. When the service receives a request, it routes that request to the datacenter that best matches the required criteria

A TCP/IP based system was built to investigate the feasibility of a VIC as per Fig. 1. This considers routing Microsoft Azure workloads to datacenters around the world to best satisfy the required criteria. Three criteria were applied: (1) reduce load on a particular electricity grid at peak times, (2) follow green energy and low emissions energy around the world with computation, thus reducing curtailment of renewables and facilitating more renewable energy and (3) take advantage of variable electricity market prices.

Furthermore, many markets grant Capacity Payments to eligible generators and interconnectors for being available to follow dispatch instructions, irrespective of actual generation. VICs would also be eligible to receive such payments but they should be directly to the VICO rather than any users. This allows users to bid without the influence of capacity payments and rewards the datacenters providing the VIC.

“A reporting organization should not purchase renewable electricity and simply apply it to scope 3 emissions without involvement from its supplier or customer.” Renewable Electricity Procurement on Behalf of Others: A Corporate Reporting Guide (page 4), EPA, 2022.

Microsoft’s 2021 Environmental Sustainability Report includes 11 of the 15 scope 3 categories (page 19), while Google reports business travel and employee commuting as one total and “other” scope 3 emissions in a second total (page 11). Apple(page 84) and Amazon (page 97) report lifecycle emissions from customer trips to physical stores under scope 3 which are not categories prescribed by the GHG

Certigy, a European EAC registry, has enabled hourly certification across many EU countries

Apple, which has a relatively long history of reporting its scope 3 emissions, states in its 2022 Environmental Progress Report that it is actively evolving its scope 3 accounting methodology. “In fiscal year 2017, we started calculating scope 3 emissions not listed above. In fiscal year 2021, these include electricity transmission and distribution losses [...] and life cycle emissions associated with renewable energy. We have not accounted for emissions resulting from employees working from home [...] we are still evolving our methodology.“ Environmental Progress Report (page 84), Apple, 2022

This also explains why, even though Norway’s grid-levelemissions factor is 10 kg CO2/MWh17 (98% carbon-free), the residual

emissions factor is 402 kg CO 2/MWh (7.4% renewable), reflectingthat most EACs produced within the Norwegian grid are claimedand retired outside of the country.

Data demonstrate that many companies do indeed pursue thispractice. For example, Norway was responsible for 43% of allguarantees of origin (GOs) exports in Europe in 2022, many ofwhich were purchased by companies whose operations have noconnection to the Norwegian grid on which these EACs wereproduced.

Wind and solar are, of course, intermittent, but battery costs too are plummeting, to the extent that they often underbid so-called peaking plants burning natural gas

This article in effect requires local authorities to only use data centres that a fully compliant with the requirements of the specified directives.

Article 33 Delegated Acts 3. The Commission is empowered to adopt delegated acts in accordance with Article 34 to supplement this Directive by establishing, after having consulted the relevant stakeholders, a common Union scheme for rating the sustainability of data centres located in its territory. The Commission shall adopt the first such delegated act by 31 December 2023. The common Union scheme shall establish the definition of data centre sustainability indicators and shall set out the key performance indicators and the methodology to measure them.

5. By 15 May 2025, the Commission shall assess the available data on the energy efficiency of data centres submitted to it pursuant to paragraphs 1 and 3 and shall submit a report to the European Parliament and to the Council, accompanied, where appropriate, by legislative proposals containing further measures to improve energy efficiency, including establishing minimum performance standards and an assessment on the feasibility of transition towards a net-zero emission data centres sector, in close consultation with the relevant stakeholders

. The Commission shall establish a European database on data centres that includes information communicated by the obligated data centres in accordance with paragraph 1. The European database shall be publicly available on an aggregated level.

We think that the threshold for reporting being 500kw is too low, as it will not pick up aggregated edge sites (organisations that have multiple facilties that individually are below the threshold but aggregated would be considerably higher), Mobile Phone basestation sites and Points of Presence (PoPs)

This links back to the lower limit for reporting of 500kw, clearly the EC see no reason to collect data from 'distributed compute' such as individual server rooms (at this time)

This is very interesting, we've seen some national government initatives in various countries relating to the collection of data centre energy data, in the UK we have the Climate Change Agreement for Data Centres which started in 2014 and according to the latest figures (4th Period) indicated that total UK energy use of the period for commercial data centres (colocation sites) was 12TWh. Back to the EED and the very interesting thing is the mention of 'interventions' will this mean the imposition of fines for poor energy performance?

This introduces the requirement for a data centre register and the rating of data centres for sustainabilty, this could become an utter bag of worms, as sustainability is closely linked to the amount of renewable energy systems on an individual country grid, the 'grid mix' and could favour those countries and data centres that are directly linked to low carbon energy sources (Norway, Sweden, Finland (Hydro), France (Nuclear), Spain (Solar/Wind) & Denmark (Wind).

It’s pretty simple: don’t let carbon removal excuse ongoing or worsening emissions. That means no deal with fossil fuel majors. And if you really must sell carbon credits, here’s my idea: they can only apply to the earliest emissions first. Once we’ve dealt with the ~2,500 ish human-added CO2 gigatonnes in the atmosphere, THEN you can apply credits to new emissions. We go from oldest to newest, not from newest to oldest.

This approach results in our Scope 2 market-based emissions being greater than zero, per the Greenhouse Gas Protocol Scope 2 Guidance, despite us achieving our 100% renewable energy match globally.

Electricity purchased from renewable sources (%) is calculated on a calendar-year basis, dividing the volume of renewable electricity (in megawatt-hours) procured for our global operations (i.e., renewable energy procured through our PPA contracts, on-site renewable energy generation, and renewable energy in the electric grids where our facilities are located) by the total volume of electricity consumed by our global operations. This metric includes all renewable energy purchased, regardless of the market in which the renewable energy was consumed

Will Let’s Encrypt issue Organization Validation (OV) or Extended Validation (EV) certificates? We have no plans to issue OV or EV certificates.

If the signature over the nonce is valid, and the challenges check out, then the agent identified by the public key is authorized to do certificate management for example.com. We call the key pair the agent used an “authorized key pair” for example.com.

Reverse proxy implementation in nginx includes in-band (or passive) server health checks. If the response from a particular server fails with an error, nginx will mark this server as failed, and will try to avoid selecting this server for subsequent inbound requests for a while.

Without having to take any risk themselves, they collect increasing profits that are indirectly paid for almost entirely by the European taxpayer. At the current interest rates, this costs the European treasuries 135 billion annually. Dutch banks receive about 11 billion of that sum, of which only 8 billion – 5.8 per cent of total payments – is being borne by Dutch taxpayers. The rest is being paid for by the taxpayers of other European countries, because the interest payments of all central banks within the Eurosystem are mutually settled via a fixed capital key.

WattCarbon decarbonization projects are measured using official government grid data1, site level metered energy data, and open source avoided energy use methodologies2, which provides the highest degree of transparency and integrity for every project on our marketplace.

Players confront challenges mirroring those in the real world: they extinguish forest fires, obstruct illegal logging, replant native trees and clean up rivers.

It proved to be so effective that criminalisation spread across Latin America and is now deployed globally as part of a playbook of tactics to divide communities, and detract attention away from legitimate debate and protests about environmental and climate harms.

Experts say that what happened here helped to establish criminalisation as a go-to tool for polluting industries and governments seeking to discredit and silence activists. Guatemala was a textbook example of a draconian crackdown, becoming a laboratory of sorts, with arbitrary charges used against countless community leaders opposing environmentally destructive projects.

As plaintiffs’ counsel Nate Bellinger, senior staff attorney at Our Children’s Trust, stated in his closing: “It’s worth remembering other times in our nation’s history when the political process didn’t work to protect people’s basic human rights. Segregation, women’s rights, equal and adequate public schooling, marriage—time and time again, the political will of powerful majorities was struck down by courts, based on the compelling evidence before them, courageously correcting the injustices thrust on the people. Today, the injustice squarely before this Court is the proven harms of these young people wrought by climate change caused by a fossil fuel-based energy system imposed and perpetuated through the law.”

But as climate policy analyst Peter Erickson explained during his expert testimony on the plaintiffs’ side, Montana’s total annual CO2 emissions – 166 million tons (based on 2019 data) – are on par with annual emissions of entire countries like the Netherlands and Pakistan. “To call [Montana’s] emissions miniscule is then to call the emissions of over 100 countries of the world miniscule,” Erickson said. “Montana’s emissions matter”, he emphasized.

You may have heard of the 3-2-1 backup strategy. It means having at least three copies of your data, two local (on-site) but on different media (read: devices), and at least one copy off-site.

The value of provenance information  Adding provenance information to media to combat misinformation is not a new idea, and early research seems to show that it could be promising: one project from a master’s student at the University of Oxford, for example, found evidence that users were less susceptible to misinformation when they had access to provenance information about content.

They also worked their media mogul pals, like Mike Bloomberg, who added their names to the "Friends of Mike" list that Bloomberg reporters were required to consult before writing negative coverage

Full text seach is a way to avoid these two issues. With SQLite, you enable full text search by creating what is called a "virtual table" using one of the FTS engines included with SQLite: FTS4 or FTS5. FTS5 support is the most recent and has more advanced searching features, including ranking and highlighting of results and is what is described here.

Let’s dissect this piece of Mojo code. First, you'll notice that we have new variable declarations let and var which may look odd at first glance since this is not familiar Python syntax. Mojo offers optional (except in some cases, more on that later) variable declarations to declare variables as immutable with let (i.e. cannot be modified after creation) or mutable with var (i.e. can be modified).

In this example we have run sysbench --cpu-max-prime=25000 --threads=1 --time=10 --test=cpu --events=0 --rate=0 and put a CPU % limiting on the process and increased that in 10% increments. The blue curve has been done with the schedutil CPU frequency govenor which dynamically scales the CPU frequency. And the red curve has been done with the performance scaling govenor which scales the CPU frequency to a maximum as soon as even a minimum amount of load happens on a core.

Suprisingly we see that on an unloaded system the energy actually increases! The assumption made here is that the cost per instruction goes down. This is an effect that can also be seen in SPECPower benchmarks where the sweet-spot for a system is typically somewhere around the higher third quarter of the peak performance.

The legislative proposal risks rendering obsolete such ambitious and holistic industry-led initiatives that provide a tool for more informed consumer decisions, encourage improvements by manufacturers and demonstrate European leadership on sustainability questions. The Regulation should instead enable such schemes (which go beyond environmental claims, and consider aspects like durability, recyclability, etc.) to continue being used.

These companies start with people who have the least agency and social power and wreck their lives, then work their way up the privilege gradient, coming for everyone else. It's called the "shitty technology adoption curve":

Funneled into the colocation space, this rising demand has almost completely saturated Tier I data center markets like Ashburn, Dallas, and Silicon Valley. As a result, hyperscale workloads are driving growth in Tier II and Tier III markets, occupying existing capacity and spurring new developments.
