AI can help us fight climate change. But it has an energy problem, too

[ad_1] Data centres that store and process algorithms use a lot of energy but there is little discussion about their environmental impact.

To truly benefit from the technology’s climate […]

A decade of renewable energy investment, led by solar, tops US $2.5 trillion

[ad_1] Solar power will have drawn half – USD 1.3 trillion – of the USD 2.6 trillion in renewable energy investments made over the decade. Solar capacity alone will have grown from 25 GW at the beginning of 2010 to an expected 638 GW by the close of 2019 – enough to produce all the […]

Ultrathin 3-D-printed films convert energy of one form into another

[ad_1] MIT researchers have 3-D printed ultrathin ceramic films that convert energy from one form into another for flexible electronics and biosensors. Here, they’ve printed the piezoelectric films into a pattern spelling out “MIT.” Credit: Massachusetts Institute of Technology MIT researchers have developed a simple, low-cost method to 3-D print ultrathin films with high-performing “piezoelectric” […]

Fair comparison of desalination technologies puts heat on energy sources

Global water demand reached roughly 4000 billion cubic […]

Jumbo electric vehicle has energy bragging rights at no charge

[ad_1] Enticed car watchers see e-car designs that look like James Bond-like sleekmobiles ready for valet parking near some island casino. Meanwhile, what about the other world of heavy-duty trucks for mining and construction? No way, have said skeptics, because battery needs made this idea impractical. E&T explained that experts had been debating “whether the […]

Experiments with a single atom rule out the 'fifth force' theory of dark energy

[ad_1] One possible explanation for the phenomenon is that dark energy is the fifth force acting on matter, along with the gravitational, electromagnetic, and strong and weak nuclear forces. Recently a team at Imperial College London decided to test this fifth force theory by performing an experiment on single atoms. The experiment worked by examining […]

AI system optimally allocates workloads across thousands of servers to cut costs, save energy

[ad_1] A novel system by MIT researchers automatically “learns” how to allocate data-processing operations across thousands of servers. A novel system developed by MIT researchers automatically “learns” how to schedule data-processing operations across thousands of servers—a task traditionally reserved for imprecise, human-designed algorithms. Doing so could help today’s power-hungry data centers run far more efficiently. […]

Pollution-free hydrogen: green energy breakthrough?

[ad_1] Credit: CC0 Public Domain Scientists said Tuesday they have developed a way of extracting hydrogen from oil without releasing greenhouse gases—a breakthrough they hailed as a “silver bullet” for cleaner energy and the climate. Unlike petrol and diesel, hydrogen produces no pollution when burned. It is already used by some car manufacturers to power […]

Macro-energy systems—the science of the energy transition

[ad_1] Phenomena of interest to macro-energy systems are listed in bold. Credit: Patricia Levi In a perspective published in Joule on August 14, a group of researchers led by Stanford University propose a new academic discipline, ‘macro-energy systems,’ as the science of the energy transition. What types of electricity storage could have the biggest impact […]
