2:02a	Amazon Says It Now Runs On 100% Clean Power. Employees Say It's More Like 22% Today, Amazon announced that it reached its 100% renewable energy goal seven years ahead of schedule. However, as Fast Company's Adele Peters reports, "a group of Amazon employees argues that the company's math is misleading." From the report: A report (PDF) from the group, Amazon Employees for Climate Justice, argues that only 22% of the company's data centers in the U.S. actually run on clean power. The employees looked at where each data center was located and the mix of power on the regional grids -- how much was coming from coal, gas, or oil versus solar or wind. Amazon, like many other companies, buys renewable energy credits (RECs) for a certain amount of clean power that's produced by a solar plant or wind farm. In theory, RECs are supposed to push new renewable energy to get built. In reality, that doesn't always happen. The employee research found that 68% of Amazon's RECs are unbundled, meaning that they didn't fund new renewable infrastructure, but gave credit for renewables that already existed or were already going to be built. As new data centers are built, they can mean that fossil-fuel-dependent grids end up building new fossil fuel power plants. "Dominion Energy, which is the utility in Virginia, is expanding because of demand, and Amazon is obviously one of their largest customers," says Eliza Pan, a representative from Amazon Employees for Climate Justice and a former Amazon employee. "Dominion's expansion is not renewable expansion. It's more fossil fuels." Amazon also doesn't buy credits that are specifically tied to the grids powering their data centers. The company might purchase RECs from Canada or Arizona, for example, to offset electricity used in Virginia. The credits also aren't tied to the time that the energy was used; data centers run all day and night, but most renewable energy is only available some of the time. The employee group argues that the company should follow the approach that Google takes. Google aims to use carbon-free energy, 24/7, on every grid where it operates.

3:30a	China Building Two-Thirds of World's Wind and Solar Projects An anonymous reader quotes a report from The Guardian: The amount of wind and solar power under construction in China is now nearly twice as much as the rest of the world combined, a report has found. Research published on Thursday by Global Energy Monitor (GEM), an NGO, found that China has 180 gigawatts (GW) of utility-scale solar power under construction and 15GW of wind power. That brings the total of wind and solar power under construction to 339GW, well ahead of the 40GW under construction in the US. The researchers only looked at solar farms with a capacity of 20MW or more, which feed directly into the grid. That means that the total volume of solar power in China could be much higher, as small scale solar farms account for about 40% of China's solar capacity. Between March 2023 and March 2024, China installed more solar than it had in the previous three years combined, and more than the rest of the world combined for 2023, the GEM analysts found. China is on track to reach 1,200GW of installed wind and solar capacity by the end of 2024, six years ahead of the government's target. "The unabated wave of construction guarantees that China will continue leading in wind and solar installation in the near future, far ahead of the rest of the world," the report said. Earlier analysis suggests that China will need to install between 1,600GW and 1,800GW of wind and solar energy by 2030 to meet its target of producing 25% of all energy from non-fossil sources. Between 2020 and 2023, only 30% of the growth in energy consumption was met by renewable sources, compared with the target of 50%. Read more of this story at Slashdot. (Comment on this)
9:20p	Linus Torvalds Says RISC-V Will Make the Same Mistakes As ARM and x86 Jowi Morales reports via Tom's Hardware: There's a vast difference between hardware and software developers, which opens up pitfalls for those trying to coordinate the two teams. Arm and x86 researchers encountered it years ago -- and Linus Torvalds, the creator of Linux, fears RISC-V development may fall into the same chasm again. "Even when you do hardware design in a more open manner, hardware people are different enough from software people [that] there's a fairly big gulf between the Verilog and even the kernel, much less higher up the stack where you are working in what [is] so far away from the hardware that you really have no idea how the hardware works," he said (video here). "So, it's really hard to kind of work across this very wide gulf of things and I suspect the hardware designers, some of them have some overlap, but they will learn by doing mistakes -- all the same mistakes that have been done before." [...] "They'll have all the same issues we have on the Arm side and that x86 had before them," he says. "It will take a few generations for them to say, 'Oh, we didn't think about that,' because they have new people involved." But even if RISC-V development is still expected to make many mistakes, he also said it will be much easier to develop the hardware now. Linus says, "It took a few decades to really get to the point where Arm and x86 are competing on fairly equal ground because there was al this software that was fairly PC-centric and that has passed. That will make it easier for new architectures like RISC-V to then come in." Read more of this story at Slashdot. (Comment on this)
