Solar power in Scotland is not a little enterprise
May 4, 2015 07:25 AM - ClickGreen staff, ClickGreen
The call by WWF Scotland follows the publication of new figures revealing that there was enough sunshine in April to have met more than 100% of the electricity needs of an average home in Scotland or 99% or more of an average household’s hot water needs.
Wind turbines in Scotland also generated enough electricity on average to supply the electrical needs of 69% of Scottish households - 1.66 million homes.
Last month, it was announced that work on Scotland’s largest solar park will start later this year in Angus.
If you sit all day at a desk, please get up and walk around now and then!
May 1, 2015 08:21 AM - Universtiy of Utah
A new study suggests that engaging in low intensity activities such as standing may not be enough to offset the health hazards of sitting for long periods of time. On the bright side, adding two minutes of walking each hour to your routine just might do the trick. These findings were published in the Clinical Journal of the American Society of Nephrology (CJASN).
Numerous studies have shown that sitting for extended periods of time each day leads to increased risk for early death, as well as heart disease, diabetes and other health conditions. Considering that 80 percent of Americans fall short of completing the recommended amount of exercise, 2.5 hours of moderate activity each week, it seems unrealistic to expect that people will replace sitting with even more exercise.
Plane de-icing agents contribute to soil and groundwater contamination at airports
April 30, 2015 09:55 AM - Friedrich Schiller University Jena.
Spring has arrived in Europe with mild temperatures and sunshine. Where just a few weeks ago the ground was frozen and partly covered in snow and ice, it is now thawing. This doesn't only have an impact on the flora and fauna. Thawing results in soil and the groundwater at airports being impacted by chemicals, which are contained in melt water. The reason: Airports have to use de-icing agents during the winter, which end up on unpaved areas and infiltrate into the soils during snowmelt.
Selective logging may underestimate carbon stock
April 29, 2015 08:20 AM - Rhett A. Butler, MONGABAY.COM
Up to 64 percent of above-ground biomass in selectively logged forests may consist of dead wood left over from logging damage, argues a paper published this week in Environmental Research Letters.
A Global perspective on hazardous chemicals in the workplace
April 28, 2015 07:28 AM - United NationsChristian Friis Bach via EurActiv
Hazardous chemicals are a vital part of many industries, but lax and inconsistent safety standards put workers' health and lives at risk all over the world, writes Christian Friis Bach.
Christian Friis Bach is Under Secretary-General of the United Nations and Executive Secretary of the United Nations Economic Commission for Europe.
Millions of workers are exposed every day to hazardous chemicals around the globe, in developing and developed countries. These chemicals are purchased and shipped from all over the world and differences in language and labelling could make them even more dangerous. However, thanks to a true success story of international cooperation, the danger is abating every day. This is worth celebrating on the World Day for Safety and Health at Work
How Desalination Technology Is Helping Solve California's Drought
April 27, 2015 08:40 AM - Betty Ilovici, NoCamels
Four years of devastating droughts in California have pushed cities and counties in the Golden State to seriously consider turning to the one drinking source that is not depleting anytime soon – seawater. With the Pacific Ocean abutting their shores, water desalination may be the much-needed solution for Californians. But desalination has its disadvantages, the chief ones being the high costs and the potential environmental damage.
On Earth Day, Give Fiber Its Due...
April 22, 2015 02:14 PM - Guest Contributor, James Gowen, Verizon Chief Sustainability Officer
There's a touch of green associated with receiving phone service, using the Internet and streaming video over an all-fiber-optic network. It's not the color of laser-generated light that carries massive amounts of data through all-glass cables directly into homes and businesses. It's green in the sense of how much more environmentally friendly today’s fiber-based telecommunications networks are compared to copper wire and coaxial cable networks. Whether it's energy efficiency or reduced demand for raw materials and other resources, all-fiber networks are a winning strategy on many fronts — including environmental sustainability. As we approach the 45th celebration of Earth Day on April 22, it's a good time to reflect on how network and technology decisions made by major telecommunications companies don't just result in advanced, more reliable services. These decisions can also pay handsome dividends on the sustainability front.
US leads the world in EV adoption
April 21, 2015 03:38 PM - ClickGreen Staff, ClickGreen
The United States currently leads the world in the number of plug-in electric vehicles on the road, capturing 41% of the global market. Though the market can be traced back to the early-to-mid 1990s with the release of the Chrysler TEVan and the General Motors EV1, it wasn’t until the second wave of vehicles such as the Nissan Leaf and the Chevrolet Volt, both introduced in 2010, that plug-in electric cars started to become a success in the US.
It was Tesla Motors with its Roadster series which first entered production in 2008 that reignited this interest in the market though. The small company was founded by Martin Eberhard and Marc Tarpenning in 2003 before current CEO Elon Musk joined the company the following year and led the business to new heights with links to new battery technologies that made plug-in electrical vehicles a more viable option for everyday journeys.
Fishing impacts on the Great Barrier Reef
April 21, 2015 03:03 PM - ARC Centre of Excellence for Coral Reef Studies
New research shows that fishing is having a significant impact on the make-up of fish populations of the Great Barrier Reef. It’s long been known that environmental impacts such as climate change and pollution are amongst the drivers of change on the Great Barrier Reef. Now researchers from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) at James Cook University have found that removing predator fish such as coral trout and snapper, through fishing, causes significant changes to the make-up of the reef’s fish populations.
New oil repellant materials could help clean up oil spills
April 15, 2015 03:34 PM - Scott Gordon, University of Wisconsin-Madison
University of Wisconsin-Madison researchers have announced a significant step forward in the development of materials that can ward off oil — a discovery that could lead to new protective coatings and better approaches to cleaning up oil spills. In a new paper in the journal Advanced Functional Materials, professor of chemical and biological engineering David Lynn and assistant scientist Uttam Manna describe new coatings that are extremely oil-repellant (or "superoleophobic") in underwater environments.
