The Complex Business of Measuring Climate Change
January 31, 2011 09:03 AM - Nick Engelfried, Justmeans, Clean Techies
Have you ever wondered exactly how scientists track climate change and the warming of the world at a global level? Estimating the overall surface temperature of the Earth isn't easy when you have to account for seasonal variations across six continents and four oceans. It requires compiling data from satellites positioned high up in the atmosphere and from hundreds of meteorological stations scattered across the globe. However being able to compare average global temperatures from year to year is incredibly important, and allows scientists to track the progress of climate change.
Deepwater Wind Farm to Use New Design
December 21, 2010 08:29 AM - Yale Environment 360 , Clean Techies
A Rhode Island company is planning to use a relatively new design for offshore wind platforms to build a large wind farm 18 to 27 miles off the coast of Rhode Island and Massachusetts. Deepwater Wind's proposed wind farm, which would use four-legged platforms to support large wind turbines, could be located in water up to 52 meters (170 feet) deep. That is more than twice the depth of conventional "monopole" wind turbines.
Turning Wastewater Into a Revenue Stream
December 1, 2010 05:21 PM - Matter Network , Clean Techies
Safely getting rid of what we flush away each day is the unglamorous role of the wastewater treatment plant. But a new process that turns sewage into high-quality fertilizer proves that creative minds can find inspiration for innovation just about anywhere.
Florida Will Build Nation’s First High-Speed Rail Corridor
October 30, 2010 08:12 AM - Crisp Green, Clean Techies
As the Obama Administration pushes for high-speed rail networks across the country, Germany's Siemens has secured a place for its Valero ICE trains in the Sunshine State. Earlier this month, Siemens presented its vision of U.S. high-speed rail to the people of Florida with the "Future of Florida High-Speed Rail Tour," a traveling exhibit featuring a full-sized model of the Velaro high-speed train.
PepsiCo Seeks to Surpass Coke in Water Conservation in UK

International drink and snack giant PepsiCo has vowed to cut the carbon emissions and water consumption of its UK operations by 50 percent in five years.
Nuclear vs Solar: Clash of the Numbers
September 24, 2010 01:31 PM - Carlo Ombello, Clean Techies
A very interesting and controversial study emerged recently, comparing nuclear and solar costs no less. The study focused on the costs of electricity in North Carolina (US), describes the solar photovoltaic (PV) business, summarizing its history of sharply declining prices, along with the very different path taken in recent years by nuclear power, whose costs have been steadily rising.
Why Tidal Power is Europe’s Best Near-Term Ocean Energy Technology
September 14, 2010 08:54 AM - Matter Network, Clean Techies
Primitive tidal mills operated in the England date back to the 11th century. During the 18th century, several tidal mills popped up in Western Europe. The news that the world's largest tidal turbine — 1 MW in size — will be installed off the coast of Scotland near Orkney should come as no surprise.
Energy Efficiency and PV: Together Forever
September 10, 2010 08:37 AM - Elisa Wood , Clean Techies
We have seen a marriage of the energy efficiency and solar energy industries as the US has worked to green its buildings. In fact, some financing programs require that all cost-effective efficiency be pursued before solar panels are installed. Here Elisa Wood interviews Liz Merry, owner of Verve Solar Consulting, about how the solar industry views energy efficiency and the outlook for companies that tackle both EE and PV.
France to Have 3,000 MW of Offshore Wind by 2015
September 2, 2010 08:42 AM - Edouard Stenger , Clean Techies
According to Agence France Presse (AFP), the French government will launch next month a tender for contracts of 10 billion euros ($12.6 billion) to build 3,000 MW of offshore wind capacity. 600 wind turbines will be implemented within five to ten sites in Normandy, Brittany and the regions of Pays de la Loire and Languedoc. They are scheduled to start producing electricity by 2015.
Design Competition to Determine Four New LEED Platinum Homes in New Orleans
August 27, 2010 08:47 AM - Mark Schrieber , Clean Techies
At the onset of the 5th anniversary of Hurricane Katrina, students and emerging professionals are putting their time towards helping to rebuild New Orleans in a sustainable fashion. The 2010 US Green Building Council Natural Talent Design Competition, in partnership with the Salvation Army's EnviRenew program, is preparing to have the final student and emerging professional designs for a small, green and affordable home judged by an internationally recognized panel in conjunction with the citizens of New Orleans' Broadmoor neighborhood (where the homes will be built).
