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.
