New Materials Promise to Dramatically Drop Photovoltaic Prices
April 9, 2013 08:41 AM - Cyrus Patten, Global Warming is Real
What is the single most significant barrier to widespread use of alternative energy? Is it the right wing climate change skeptics? No. It's economics. If there is not money to be made at the same scale as in the fossil fuel industry, and if renewable, clean energy does not become cheaper than fossil fuels, alternative energy doesn't stand a chance in the free market.
'Waterpod' Turns Desert Well-Water Clean
April 4, 2013 10:51 AM - Allison Winter, ENN
Ever since the construction of a hydro-electric dam in the Draa Valley nearly 40 years ago, Sahara nomads have faced further desertification of the region, taking a heavy toll on water supplies. More than 330 million people in sub-Saharan Africa, or around 40 percent of the population, do not have access to clean drinking water, according to a report published by British NGO WaterAid. While there are wells throughout the region, they often contain undrinkable brackish water that is inundated with salt.
Lead-Based Paint Still Being Sold in Developing Nations
March 28, 2013 11:52 AM - Allison Winter, ENN
Lead is added to paint mainly to speed up drying and increase durability, but due to its toxic effects has been banned in many countries. Nonetheless, lead-based paint still poses a problem as older housing stock may contain lead-based painted walls. When this paint chips, inhalation and ingestion (particularly by children) can damage the nervous system and cause a slew of health problems. Despite the uproar of concern for this type of paint in western countries, new reports show that lead paint is still being sold in poor nations. Perry Gottesfeld, lead author for an investigative study, has discovered high levels of the heavy metal in numerous house paints for sale throughout the African nation of Cameroon. Further investigation has led the research team to conclude that there’s still plenty of lead paint for sale in other developing nations. Two years ago Gottesfeld was in Cameroon, where he and collaborators at a local NGO now report they had found nearly a dozen enamel household paints with so much lead in them they exceeded the U.S. standard by 300 times or more.
Verizon Introduces 'MAGIC' Buses to Reduce Carbon Footprint
March 25, 2013 08:58 AM - Editor, Justmeans
To help reduce traffic congestion and carbon dioxide emissions in New York City, and better serve customers, Verizon has rolled out a fleet of 25 buses that will pick up company technicians at central locations throughout the city and then transport them to local job sites. The fleet - known as MAGIC, which stands for Mobile Area Garage Installation Center - removes approximately 250 Verizon trucks from the city's roads and frees up the same number of parking spots.
Sinkhole Threatens Louisiana Community
March 22, 2013 01:52 PM - Allison Winter, ENN
Sinkholes have been making headlines in the news lately like when earlier this month, a Florida man was unfortunately pulled to his death because of the mysterious land collapse. Florida in particular is prone to sinkholes because of underground limestone caverns in which the rock is extremely porous and dissolves easily in water. This softening causes land to sink and the event has the ability to collapse without warning, swallowing whatever lies above ground causing fatal destruction. While sinkholes are naturally occurring depressions in the Earth’s surface that vary in both diameter and depth, they can also be caused by man-made industries, and consequently, a massive sinkhole in Louisiana is threatening an entire community.
Happy World Water Day!
March 22, 2013 08:44 AM - Allison Winter, ENN
All across the globe, communities are celebrating International World Water Day and according the UN's World Water Day website, over 450 events have been planned this year! This year's theme is in part a reflection of the International Year of Water Cooperation. The day is also dedicated to the theme of cooperation that is emphasized concerning using water as a resource. Not only is the environment heavily dependent on water, but as a basic human need, good management of water sources is crucial to our own livelihood. In correlation with this environmental holiday, we are encouraged to promote water cooperation and do our part in protecting one of Earth's most valuable resources as this year marks the 10th anniversary of the celebration that was recommended during the 1992 UN Conference on Environment and Development. So in celebration of today, we are urging our readers to limit your water use!
Shams 1: World's Largest Concentrated Solar Plant Goes Live
March 20, 2013 08:49 AM - Tafline Laylin, Green Prophet
The Shams 1 Concentrated Solar Plant (CSP) in Abu Dhabi is the largest of its kind in the world and it has finally gone live. Green Prophet visited the 100MW plant in the western region of the United Arab Emirates earlier this year as part of a Masdar-sponsored media tour during the World Future Energy Summit (WFES), and we were deeply impressed with the project's progressive scope and size.
The Growth of Efficient Buildings
February 25, 2013 08:47 AM - Richard Matthews, Global Warming is Real
The area of building efficiency affords tremendous opportunities for both economic growth and reduced environmental impacts. Buildings are the single largest emitters of greenhouse gases. According to a UNEP study titled "Towards a Green Economy," homes and businesses are responsible for 40 percent of the climate change causing carbon pollution. There is significant room for improvement in new construction and retrofits in homes, businesses, schools and other organization.
Clean Coal Finally a Reality?
February 19, 2013 03:59 PM - J. David Thé, ENN
A team of researchers at Ohio State University (OSU) spent the past 2 years developing a clean way of harnessing the power of coal and have recently found great success in their research scale combustion system. The team is now able to harness clean coal energy chemically without combustion with air, while capturing 99% of the carbon dioxide produced from the reaction. With the next stage in testing on the horizon, could this possibly be the future of coal?
Rapid Expansion of EV Charging Stations Planned
February 18, 2013 06:29 AM - Tina Casey , Triple Pundit
The issue of electric vehicle range anxiety got a thorough airing last week, in the now notorious Tesla vs The New York Times battle. It started when Times reporter John Broder wrote a story about his recent Tesla Model S test drive. While acknowledging that the car itself is a thing of beauty (Motor Trend’s Car of the Year, to be precise) Broder detailed a litany of complaints about the driving experience on a 400-mile trip from Washington D.C. to Boston, primarily focusing on battery life and range. The whole thing ended ingloriously, short of the destination point with a spent battery and a tow truck involved. Of course, taking a 400 mile jaunt (actually more, considering that Broder detoured through New York City) along some of the most heavily traveled arteries in the U.S. during the dead of winter is a dicey proposition under any circumstances, but if Broder set out to demonstrate that electric vehicles are not ready for prime time, he ended up proving something else entirely.
