Energy-hungry AI is eating the planet. But is it also humanity's best hope?

MITEI’s Rob Stoner discusses AI’s unsustainable energy consumption. Even with the introduction of renewable energy sources—through the use of power purchase agreements (PPAs)—Stoner states that tech firms are pulling electricity from the grid faster than they can add to it.

The pros and pitfalls of hydrogen power, according to MIT energy expert

MITEI's Rob Stoner discusses hydrogen energy and the seven hydrogen "hubs" created by the Bipartisan Infrastructure Act. "[The hubs are] trying to create investment...and at the same time, they're trying to create demand for hydrogen so that will be the basis for buying and consuming hydrogen within a range of industries."

Woburn-based battery maker raises $78 million

Alsym Energy—cofounded by Kripa Varanasi (Mechanical Engineering)—is developing rechargeable batteries that match the performance of lithium-ion cells without using lithium or cobalt. Instead, the batteries use manganese oxide for one of its electrodes and a water-based electrolyte solution.

A growth spurt in green architecture

In the green building revolution, architects are increasingly using renewable, organic, and carbon-absorbing materials to decrease the environmental impact of their structures. “At this critical moment, what we architects do matters more than ever. [...] Every kilowatt-hour of solar power, every unit of zero-carbon housing, and every calorie of sustainably sourced vegetables will be multiplied across history,” states Carlo Ratti (Urban Studies and Planning).

Solar hits a renewable energy milestone not seen since WWII

Last year, solar accounted for more than half of the nation’s energy additions to the grid—the first time grid additions have been dominated by a renewable source since hydropower during WWII. The growth of renewable energy projects is “very likely to continue because solar and wind are now very well established. Solar costs continue to fall far below where we ever thought they would,” states MITEI Director Robert Stoner.

Green energy, EV sales are growing remarkably in the U.S. as emissions fall. Is it enough?

The Clean Investment Monitor database—developed by the MIT Center for Energy and Environmental Policy Research and the Rhodium Group—has found that the “U.S. is generally heading in the right direction to achieve its energy goals to combat climate change, but it could still face headwinds due to siting and permitting delays, backlogged electric grid connection requests, and supply chain challenges.”
