1. RENEWABLE ENERGY
The cure to renewable energy's intermittency problem may be more renewable energy -- study
By 2030, scaled-up green power could meet the demands of a large grid 99.9 percent of the time, according to new research from the University of Delaware. A mix of offshore and onshore wind, along with contributions from solar power, could provide reliable power flow during all but a handful of days in the hypothetical four-year period under study.
Beauty of glaciers turns nature photographer from skeptic to climate activist
What began as a fascination with the sublime forms, colors and movements of Arctic glaciers has transformed one of America's leading nature photographers into a crusader for political action on climate change. The photographer, James Balog, once thought the climate system was too complex, too large to be affected by the actions of humans. After several years of documenting the slow retreat of the Earth's ice packs through the lens of a Nikon camera, though, Balog founded a project that captures through time-lapse photography the slow degradation of glaciers in Greenland, Iceland, Alaska and the Rocky Mountains.
