Seaweed forests could help power tropical islands
April 1, 2014 06:45 AM - Jan Piotrowski, SciDevNet
Harvesting seaweed 'forests' and feeding them into large underwater digesters could one day meet the world's energy needs, with nine per cent of the ocean floor being enough to replace fossil fuels entirely, according to an ambitious idea. Even a more immediate and realistic use of seaweed — a major untapped resource — would greatly increase the self-sufficiency and sustainability of small island states, but limited investment is preventing the roll-out of relevant technologies, marine biofuel experts have said.

Despite some early March rain in California, and a few storm systems moving in this week, the late season moisture will sadly fall far short of that which is needed to pull the state out of its four-year drought.
Ground breaking battery technology promises to extend EV range
March 30, 2014 09:09 AM - BOB SHETH, Electric Forum
Over the last few years much of the talk with regards to the electric vehicle sector has focused upon battery restrictions with many people calling for greater investment in the sector. There was a general consensus emerging that lithium ion batteries had perhaps been pushed to their technological limit and we may need to strip back the battery sector and go back to square one. However, researchers at the University of Limerick have announced a ground breaking breakthrough which could effectively double the life of an electric vehicle battery. This new development incorporates the latest nanotechnology which is something that will impact every area of everyday life. It is a technology which has been around for a few years but is still in its infancy with regards to its potential to change areas such as battery storage capacity.
Cost of agriculture related emissions outweigh benefits
March 29, 2014 08:03 AM - Editor, ENN
Revenues associated with ammonia pollution generated by agriculture equate to higher than expected health care costs according to Harvard researchers Fabien Paulot and Daniel Jacob. The NASA funded study used computer models that identified the harmful ammonia emissions created by the interaction of agriculturally generated ammonia in the atmosphere.
A sooner Spring and a later Autumn suggests the new normal
March 28, 2014 10:36 AM - University of Southampton newsroom
A study by the University of Southampton suggests that on average the end of Autumn is taking place later in the year and Spring is starting slightly earlier. A team of researchers examined satellite imagery covering the northern hemisphere over a 25-year period (1982 - 2006), and looked for any seasonal changes in vegetation by making a measure of its 'greenness'. They examined in detail, at daily intervals, the growth cycle of the vegetation — identifying physical changes such as leaf cover, color and growth.
Sustainability is Important to Most American Food Shoppers, Survey Finds
March 28, 2014 08:10 AM - Phil Covington, Triple Pundit
A new survey of American consumers provides some potentially surprising findings that indicate American food shoppers are very mindful about what they place into their shopping carts, and it’s not just about price and taste. While food commercials on television constantly bombard Americans with offerings that focus on price-point and convenience, a 2014 survey by Cone Communications found that people care about where their food comes from and how it is produced.

Due to California’s historic drought, a variance was issued by the U.S. Department of Agriculture (USDA) in February that enables applicable organic livestock farmers in the Golden State to temporarily disregard the feeding standards that allow them to stamp their product as organic.
Caribbean Island of Barbados To Get Waste-To-Energy Plant
March 26, 2014 08:06 AM - Gina-Marie Cheeseman, Triple Pundit
One day soon the Caribbean island of Barbados will have part of its electricity needs supplied by a waste-to-energy plant. Cahill Energy, based in Guernsey, announced the signing of an agreement with the government of Barbados on March 15 to build and operate a waste-to-energy plant.
