In America’s low-carbon future, most cars will run on electricity, carbon dioxide will be stored underground, and homes and buildings will be hyper-efficient, guzzling less energy even as the population grows. This is the vision of a new analysis that maps how the United States can drastically curb its greenhouse gas emissions by 2050. TheRead More

International talks in Paris in 2015 could see the world’s nations agree to limit global warming to a rise of 2C. Actually achieving that target will require huge commitments – not least by developed nations
Solar and energy storage will increasingly be integrated together at commercial sites, homes and microgrids. But to be honest, they are an odd couple with very different personalities. Solar is passive: solar modules are typically planted in a fixed position to generate power for 20 or 30 years. You
Brazil’s Jaguari reservoir has fallen to its lowest level ever, laying bare measurement posts that jut from exposed earth like a line of dominoes. The nation’s two biggest cities are fighting for what little water is left.
It’s been widely publicized that the cost of residential solar electric systems in the United States is falling faster than ever before. This downward pricing trend is projected to continue through 2016 and then stabilize, according to a September 2014 report compiled by researchers
