America Takes Its Biggest Step Yet to End Coal Mining

The Washington Post reports that America took “one of its biggest steps yet to keep fossil fuels in the ground,” announcing Thursday that it will end new coal leasing in the Powder River Basin, “which produces nearly half the coal in the United States…

“It could prevent billions of tons of coal from being extracted from more than 13 million acres across Montana and Wyoming, with major implications for U.S. climate goals.”
A significant share of the nation’s fossil fuels come from federal lands and waters. The extraction and combustion of these fuels accounted for nearly a quarter of U.S. carbon dioxide emissions between 2005 and 2014, according to a study by the U.S. Geological Survey. In a final environmental impact statement released Thursday, Interior’s Bureau of Land Management found that continued coal leasing in the Powder River Basin would harm the climate and public health. The bureau determined that no future coal leasing should happen in the basin, and it estimated that coal mining in the Wyoming portion of the region would end by 2041.
Last year, the Powder River Basin generated 251.9 million tons of coal, accounting for nearly 44 percent of all coal produced in the United States. Under the bureau’s determination, the 14 active coal mines in the Powder River Basin can continue operating on lands they have leased, but they cannot expand onto other public lands in the region… “This means that billions of tons of coal won’t be burned, compared to business as usual,” said Shiloh Hernandez, a senior attorney at the environmental law firm Earthjustice. “It’s good news, and it’s really the only defensible decision the BLM could have made, given the current climate crisis….”

The United States is moving away from coal, which has struggled to compete economically with cheaper gas and renewable energy. U.S. coal output tumbled 36 percent from 2015 to 2023, according to the Energy Information Administration. The Sierra Club’s Beyond Coal campaign estimates that 382 coal-fired power plants have closed down or proposed to retire, with 148 remaining. In addition, the Environmental Protection Agency finalized an ambitious set of rules in April aimed at slashing air pollution, water pollution and planet-warming emissions spewing from the nation’s power plants. One of the most significant rules will push all existing coal plants by 2039 to either close or capture 90 percent of their carbon dioxide emissions at the smokestack.

“The nation’s electricity generation needs are being met increasingly by wind, solar and natural gas,” said Tom Sanzillo, director of financial analysis at the Institute for Energy Economics and Financial Analysis, an energy think tank. “The nation doesn’t need any increase in the amount of coal under lease out of the Powder River Basin.”

30TB hard drives will finally become mainstream next year — Japanese rival to Seagate and Western Digital reveals plans to launch two 30TB+ HDDs in 2025 using two different technologies

Toshiba will debut 30TB+ hard drives next year created using HAMR and MAMR technology.

Toshiba has announced plans to bring 30TB+ hard drives to the commercial market in 2025.

The large capacities have been made possible through two magnetic recording technologies: Heat Assisted Magnetic Recording (HAMR) and Microwave Assisted Magnetic Recording (MAMR). 

HAMR technology significantly enhances writing capabilities by heating the disk material with a near-field laser. HAMR does have its critics, with questions regarding the technology’s readiness, quality, reliability and compatibility, but all of the major drive manufactures are adopting it, and Seagate recently announced the results of an experimental test in which one of its Mozaic 3+ HAMR-equipped drives ran continuously, and problem free, for over 6,000 hours.

Yo MAMR!

Using HAMR, coupled with Shingled Magnetic Recording (SMR), which increases storage capacity by overlapping data tracks, allowed Toshiba to successfully achieve a drive capacity of 32TB over 10 x 3TB platters.

The second technology, MAMR, uses microwaves to boost magnetic recording abilities. Toshiba was a pioneering champion of this technology, having started mass production of the first-generation drives back in 2021. With the combination of SMR technology, improved signal processing, and the stacking of 11 platters, the company says it achieved 31TB capacity. 

Larry Martinez-Palomo, Toshiba’s Vice President and Head of Storage Products Division, said “Toshiba is concurrently advancing the development of future generation high-capacity HDDs using both HAMR and MAMR technologies. Mass production of hard disk drives incorporating HAMR will commence after the validation phase is completed. In the interim, Toshiba will continue to satisfy the demand for high-capacity, high-reliability storage devices with hard disk drives employing the field-proven MAMR technology.” 

Toshiba expects to begin shipping test HAMR HDDs, with a capacity ranging from 28 to 30TB, in 2025.
