  1. New material releases hydrogen from water at near-perfect efficiency Only works at UV wavelengths, but it might point the way toward general approach. Enlarge NASA/Dimitri Gerondidakis 52 with 27 posters participating Solar energy is currently dominated by photovoltaic devices, which have ridden massive economies of scale to price dominance. But these devices are not necessarily the best choice in all circumstances. Unless battery technology improves, it's quite expensive to add significant storage to solar produ
  2. The UK Just Got More Power From Renewables Than Fossil Fuels, a First Since 1882 Photo: Getty It’s been an eventful year for carbon-free energy in the UK. First, Great Britain went a week without coal for the first time since the Industrial Revolution. Then the country fired (wound?) up the world’s largest offshore wind farm.

University of Rhode Island Each year, the US Energy Information Agency is required to track trends in the nation's energy markets and project those trends forward. Projections based on 2019's trends were released this week, and for the first time, the EIA's default projection places renewables as the largest single source of electri
  5. Does renewables pioneer Germany risk running out of power? FRANKFURT (Reuters) - Germany, a poster child for responsible energy, is renouncing nuclear and coal. The problem is, say many power producers and grid operators, it may struggle to keep the lights on.

Photo by Photofusion/Universal Images Group via Getty Images When we think about climate change, we most often think about emissions from two sectors: energy and transportation. But industry makes a big contribution to climate change, too. Industrial emissions come from a lot of different things, including the manufacture of common chemi
