Aluminum-ion battery technology advances
April 27, 2015 06:56 AM - Mark Shwartz, The Ecologist

A new high-performance 'aluminum-ion' battery could be the technical breakthrough needed to boost the renewable energy takeover. It's safe, uses abundant low-cost materials, recharges in one minute and withstands many thousands of recharge cycles.

If this new battery lives up to expectations, it could propel a whole new chapter in the renewable takeover of the world's energy supply.

Stanford University scientists have invented the first high-performance aluminum battery that's fast-charging, long-lasting, inexpensive - and safe.

Cleaner buses could result in fewer school absences
April 23, 2015 12:32 PM - ClickGreen Staff, ClickGreen

The use of clean fuels and updated pollution control measures in the school buses 25 million children ride every day in the United States could result in 14 million fewer absences from school a year, based on a study by the University of Michigan and the University of Washington. In research believed to be the first to measure the individual impact on children of the federal mandate to reduce diesel emissions, researchers found improved health and less absenteeism, especially among asthmatic children.

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.

Energy-tracking app encourages sustainable behaviors
April 22, 2015 01:33 PM - Editor, ENN

We've all heard of fitness trackers and apps that help us stay on track with our daily nutrition and exercise, but what about an app to monitor our personal energy usage and carbon footprint? Just in time for Earth Day, a team at the University of Wisconsin-Madison has created an energy-tracking app to make reducing day-to-day energy usage more accessible.

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.

US energy-related CO2 emissions increase for second year in a row
April 20, 2015 10:23 AM - ClickGreen Staff, ClickGreen

For the second year in a row, energy-related carbon dioxide (CO2) emissions in the United States have increased, according to the latest official figures. However, unlike 2013, when emissions and gross domestic product (GDP) grew at similar rates (2.5% and 2.2%, respectively), 2014's CO2 emissions growth rate of 0.7% was much smaller than the 2014 GDP growth rate of 2.4%.

Electric vehicle sales booming in France, Germany, UK
April 20, 2015 08:12 AM - ClickGreen Staff, ClickGreen

France is leading Europe’s electric vehicle revolution with the nation now accounting for more than a quarter of EV sales across the EU, new figures reveal.

Data released by the European Environment Agency shows around 38 000 electric vehicles were registered in 2014, up by 57 % compared to 2013. 

Solar power and Native American rights clash in the Mojave Desert
April 18, 2015 10:00 AM - Roy L Hales & Robert Lundahl, ECOreport

In a remote corner of the Mojave Desert, 15 miles from Las Vegas, stands the expansive Ivanpah Solar Electric Generating System. Occupying 5 square miles, the facility seems to swallow up a stunning expanse of desert including animals, plants and now, spiritual and cultural resources.

Native elders filed a suit against the Department of the Interior, Bureau of Land Management, and the Department of Energy in 2010, for failure to properly consult with the tribes in regard to the development of six renewable projects.

Litigants Alfredo Figueroa (Yaqui/Chemehuevi), Phillip Smith (Chemehuevi), and Reverend Ron Van Fleet (Mojave) complain that the government and the companies involved have lent a deaf ear to their concerns, which has brought a new level of anxiety and spiritual pain to people who have long felt their voices muffled in the face of commercial development by others.

New report identifies possible next steps in US energy development
April 9, 2015 10:09 AM - American Geosciences Institute via EurekAlert!

The U.S. energy portfolio changes over time. Scientific and technologic advances related to hydraulic fracturing have dramatically increased the supply of U.S. oil and gas; because of this, a methane economy - in which natural gas provides the leading share of primary energy consumption - is now a possible scenario for U.S. energy development. In a report released by the American Geosciences Institute (AGI), the social, political, technical and environmental components of a methane economy are identified. The report also addresses how industry, government and the public might best work together to advance common energy goals.

Fracking appears to be linked to rise in radon levels in Pennsylvania homes
April 9, 2015 06:35 AM - JOHNS HOPKINS UNIVERSITY BLOOMBERG SCHOOL OF PUBLIC HEALTH, via EurekAlert.

Johns Hopkins Bloomberg School of Public Health researchers say that levels of radon in Pennsylvania homes - where 42 percent of readings surpass what the U.S. government considers safe - have been on the rise since 2004, around the time that the fracking industry began drilling natural gas wells in the state.

The researchers, publishing online April 9 in Environmental Health Perspectives, also found that buildings located in the counties where natural gas is most actively being extracted out of Marcellus shale have in the past decade seen significantly higher readings of radon compared with buildings in low-activity areas. There were no such county differences prior to 2004. Radon, an odorless radioactive gas, is considered the second-leading cause of lung cancer in the world after smoking.
