Earth's oxygen-rich atmosphere emerged in whiffs from a kind of blue-green algae in shallow oceans around 2.5 billion years ago, according to new research from Canadian and US scientists.
The warming of arctic waters in the wake of climate change is likely to produce radical changes in the marine habitats of the High North. This is indicated by data from long-term observations in the Fram Strait, which researchers from the Alfred Wegener Institute (AWI) have now analysed. Their most important finding: even a short-term influx of warm water into the Arctic Ocean would suffice to fundamentally impact the local symbiotic communities, from the water's surface down to the deep seas. As the authors recently reported in the journal "Ecological Indicators", that's precisely what happened between 2005 and 2008.
Canadian Solar Inc. (the "Company", or "Canadian Solar"), one of the world's largest solar power companies, today announced that its wholly owned subsidiary, Recurrent Energy, one of North America's largest solar project developers, closed on a tax equity investment commitment with GE unit GE Energy Financial Services for the 100 megawatt (MWac) Astoria solar power project. Recurrent Energy also closed a debt facility for the Astoria project, currently under construction in California.
Amazon Web Services, Inc. (AWS), an Amazon.com company, today announced that it has contracted with EDP Renewables to construct and operate a 100 megawatt (MW) wind farm in Paulding County, Ohio, called the Amazon Wind Farm US Central. This new wind farm is expected to start generating approximately 320,000 megawatt hours (MWh) of wind energy annually starting in May 2017, or enough to power more than 29,000 US homes in a year.
Tabuchi Electric, a solar-plus-storage manufacturer, is unveiling the installation of its first solar-plus-storage system as part of a broader program being led by utility partner Oshawa Power and Utilities Corporation in Ontario, Canada. The utility is one of the first in North America to lead the installation of grid-friendly residential solar-plus-storage systems.
Côte-de-Beaupré Regional County Municipality ("RCM") and Boralex Inc. ("Boralex" or the "Corporation") are pleased to announce commercial commissioning of the Côte-de-Beaupré community wind farm project. This 23.5 MW capacity project is located on the private lands of the Seigneurie de Beaupré, in the Côte-de-Beaupré region, Québec.
The U.S. Green Building Council (USGBC), presenter of Greenbuild, the world's premier sustainability and green building conference, selected LG Electronics USA as official solar partner for the 2015 trade show this week in Washington, D.C.
Tri Global Energy LLC, a leading originator and developer of community-sponsored utility-scale wind energy projects, announces the close of a transaction with TERNA ENERGY, S.A., a member of GEK TERNA Group of Companies, for the acquisition, construction and operation of the Fluvanna Wind Energy Project, a 380 megawatt (MW) wind project located in Fluvanna, Texas.
Some argue the transportation sector constitutes a major roadblock on the path to avoiding dangerous climate change. Yet, the sector has the capacity to nearly halve its CO2 emissions by 2050, and may therefore be easier to decarbonize than previously thought. Realizing such a major emissions cut would require further efficiency improvements in fuel consumption and, especially, the promotion of public transport in cities, alongside a large-scale shift to electric cars. These are key findings of the new article published in the journal Science.
Do you know how many small, sustainable actions you take every day, and how they stack up to save energy and water and reduce waste? Students in the Warner College of Natural Resources recently got the chance to find out how much turning off lights and turning the thermostat down adds up. At the same, time, they helped the City of Fort Collins with market research on a mobile app, “Lose a Watt,” that encourages sustainable behaviors.
There's an ancient group of algae that evolved in the world's oceans before our backboned ancestors crawled onto land. They are so numerous that their gigantic blooms can affect the weather, and they account for 30 to 40 percent of all photosynthesis in the world's oceans.
The production of energy from natural gas without generating carbon dioxide emissions could fast become a reality, thanks to a novel technology developed by researchers of the Institute for Advanced Sustainability Studies (IASS) in Potsdam and the Karlsruhe Institute of Technology (KIT). In a joint project initiated by Nobel Laureate and former IASS Scientific Director Professor Carlo Rubbia, the two institutions have been researching an innovative technique to extract hydrogen from methane in a clean and efficient way. After two years of intensive experiments the proof-of-principle has now been provided. With the experimental reactor running reliably and continuously, the future potential of this technology has become apparent.
Global leader Premier Tech Aqua (PTA), the Environmental Technologies Group of Premier Tech, celebrates 20 years of innovation in water preservation and product development by expanding its leading-edge and ecological onsite wastewater treatment Ecoflo Biofilter product line, by introducing its newly NSF-certified Ecoflo Coco Filter.
Cornell researchers will travel to Paris in early December as part of the university’s delegation to the global climate change summit, COP21. Even in the wake of the recent Parisian terrorist attacks, delegations from over 190 countries and more than 50,000 people from all over the world are expected to attend.
Inspired by the natural process of photosynthesis in plants, which converts energy from the sun into sugars, new solar cells have been developed that display 'artificial photosynthesis'. The cells convert carbon dioxide emissions into solar fuel and even function effectively if they are placed underwater.
