New method for waking up devices

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.

Avoiding blackouts with 100% renewable energy

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.

New map profiles induced earthquake risk

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.

Winds of change for vertical axis turbines?

New research suggests vertical axis turbines, which may have fewer impacts on birds and the environment, could increase public support for new wind energy installations.

Hopeful signs despite growing carbon emissions

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.

Double-duty textile could warm or cool

A team led by Yi Cui has created clothing fabric that keeps in warmth on cool days and releases heat on warm ones. The new textile could save energy costs from cooling or heating buildings.

Effects of rolling back the Clean Power Plan

Early October the EPA moved to roll back the Obama-era Clean Power Plan. Stanford legal and economic experts discuss this move and what it means for attempts to reduce greenhouse gas emissions.
