A device that’s turned off doesn’t suck battery life, but it also doesn’t work. Now a low-power system that’s always on the alert can turn devices on when they are needed, saving energy in the networked internet of things.
Researchers propose three separate ways to avoid blackouts if the world transitions all its energy to electricity or direct heat and provides the energy with 100 percent wind, water and sunlight. The solutions reduce energy requirements, health damage and climate damage.
A map created by Stanford geophysicists can help predict which parts of West Texas and New Mexico may be at risk of fracking-induced earthquakes. The map could guide oil discovery efforts in the region.
A team of scientists including Lynette Cegelski and graduate student Wiriya Thongsomboon have discovered a new type of cellulose that offers opportunities for multiple advances from renewable fuel to antibiotics.
An international research team reports that the increase in global carbon dioxide emissions from fossil fuels has resumed after a 3-year respite and may increase again next year. Despite the findings, improved energy efficiency and a booming renewables market provide signs of hope.
