The rapidly rising levels of carbon dioxide in the atmosphere affect plants’ absorption of nitrogen, which is the nutrient that restricts crop growth in most terrestrial ecosystems. Researchers at the University of Gothenburg have now revealed that the concentration of nitrogen in plants’ tissue is lower in air with high levels of carbon dioxide, regardless of whether or not the plants’ growth is stimulated. The study has been published in the journal Global Change Biology.
Using a novel energy efficient façade improves the comfort of residents while saving them money
Catalysts created by Carnegie Mellon University chemist Terrence J. Collins effectively and safely remove a potent and dangerous endocrine disruptor from wastewater.
The figures are impressive: from 15 to 55 employees in just over 1.5 years, a brand-new 4’500 square meter pilot production plant in Niederhasli in the outskirts of Zurich with a production capacity of 15 MW (megawatts) in installed solar energy and another financing round of CHF 10 million.
With warming summer temperatures across Alaska, white spruce tree growth in Interior Alaska has declined to record low levels, while the same species in Western Alaska is growing better than ever measured before.
An amendment has been approved by the Mid-Atlantic Fishery Management Council this week for the creation of “deep sea coral zones” in the Mid-Atlantic as a measure to protect deep sea corals that are vulnerable to damage from bottom-tending fishing gear. On approval from the Secretary of Commerce, the zones will be formed in the regions where corals have been widely found or likely to be present.

Variations in the amount of oxygen in Earth’s atmosphere significantly altered global climate throughout the planet’s history. Efforts to reconstruct past climates must include this previously overlooked factor, a new University of Michigan-led study concludes.
Iberdrola Renewables today announced a 25-year contract to supply Tri-State Generation and Transmission Association, Inc. (Tri-State) – a wholesale electric power supplier owned by 44 electric cooperatives and public power districts across Colorado, Nebraska, New Mexico and Wyoming – with renewable energy from the planned Twin Buttes II Wind Project.
San Antonio-based OCI Solar Power LLC is announcing the start of construction on the 110-megawatt (MW) Alamo 6 solar plant located in Pecos County, Texas. Once constructed, this will be the largest solar plant in Texas and one of the largest dual-axis solar projects in the world.
At a ceremony held at the Intersolar Europe trade show in Munich, Germany, Dr. Lutz Henckels, CEO of HiQ Solar received the Award for solar innovation for the TrueString 480V. "HiQ Solar's device is a worthy winner of the Intersolar Award 2015," said the judging panel.
As the climate warms, glaciers and other terrestrial ice reservoirs will release massive amounts of organic carbon into the water circulation. Just how much and how quickly it will be released is the focus of a recent Nature Geoscience publication.
Petrel fledglings leave the nest after dark, but these marine birds' maiden flights towards the sea are hampered by city lights. Many collide or fall to the ground where they are in danger of being run over and vulnerable to predators. Now, a study has evaluated the impact of light pollution on three species of petrels on the Balearic Islands, including the Balearic shearwater, the most threatened sea bird in Europe, and concludes that between 30 and 47% of colonies are exposed to high levels of light pollution.
Leading LED lighting manufacturer LG Electronics today announced an important milestone in its collaboration with Davenport University. LG is supplying super-efficient fixtures across all of Davenport's campuses across the Great Lakes State as part of a multi-year program to convert existing lighting to energy-efficient LED solutions by 2018. Davenport has already installed more than 600 LG LED fixtures as part of this initiative, including troffers, tubes and cans.
Amazon Web Services, Inc. (AWS), an Amazon.com company, today announced that it has teamed with Community Energy, Inc. to support the construction and operation of an 80 megawatt (MW) solar farm in Accomack County, Virginia, called Amazon Solar Farm US East. This new solar farm is expected to start generating approximately 170,000 megawatt hours (MWh) of solar power annually as early as October 2016 – or the equivalent of that used by approximately 15,000 US homes1 in a year.
The world´s new solar power leader, Hanwha Q CELLS, has put the 8.1MW "Tower Hill" solar farm into operation in South Gloucestershire, in the Southwest of England. Hanwha Q CELLS, owner of the project rights for the Tower Hill farm, managed the EPC (Engineering, Procurement, Construction) and will be responsible for O&M (Operations & Maintenance).
