Origami inspires highly efficient solar steam generator

Water covers most of the globe, yet many regions still suffer from a lack of clean drinking water. If scientists could efficiently and sustainably turn seawater into clean water, a looming global water crisis might be averted. Now, inspired by origami, the Japanese art of paper folding, researchers have devised a solar steam generator that approaches 100 percent efficiency for the production of clean water. … read more

Solar Head of State: An Interview with Director and Co-Founder James Ellsmoor

While solar power lags behind the annual generation provided by many other renewable energy sources (including hydroelectric, wind, and biomass/biowaste), the future of solar is bright for two main reasons. First, solar power remains the greatest source of new power capacity installed worldwide year after year, meaning eventually it will overtake other energy sources currently […]

Cover the U.S. In 89 percent trees, or go solar

Researchers found that using bio-sequestration to capture carbon produced by US coal-fired plants even after carbon capture and storage would require using 62 percent of the nation's arable land for that process, or 89 percent of all US land with average forest cover. In comparison, offsetting the amount of carbon produced by manufacturing solar panels is 13 times less land, making it a far more viable option. … read more

Large wind and solar farms in the Sahara would increase heat, rain, vegetation

Wind and solar farms are known to have local effects on heat, humidity and other factors that may be beneficial -- or detrimental -- to the regions in which they are situated. A new climate-modeling study finds that a massive wind and solar installation in the Sahara Desert and neighboring Sahel would increase local temperature, precipitation and vegetation. Overall, the researchers report, the effects would likely benefit the region. … read more

Adding power choices reduces cost and risk of carbon-free electricity

Researchers find that including a variety of zero-carbon power sources is a more cost effective way of lowering greenhouse gas emissions than relying solely on solar, wind, and batteries. … read more
