U.S. Federal Government Amps Up E-Waste Reuse and Recycling
May 6, 2014 07:59 AM - Leon Kaye, Triple Pundit
The U.S. federal government is the nation's largest consumer and disposer of electronics. Considering the number of federal employees—about 2.7 million at last count, not including the military or courts—U.S. government employees contribute a massive portion to the approximate 2.4 million tons of electronic waste, or e-waste, that is discarded annually. Not only are those monitors, printers, cell phones and all those peripherals leeching chemicals into soil and water supplies, government (as well as companies) leave money on the table thanks to all of those rare earth minerals allowing them to function in the first place.

Volkswagen unveiled the latest updates to its popular VW Jetta line at this year’s New York International Auto Show. The car will get a few minor styling tweaks, but what interests us are the improvements under the hood—where fuel efficiency counts.
New hopes for getting the lead out of solar
May 5, 2014 10:16 AM - Robin Blackstone, ENN
Solar energy is arguably our most viable low cost energy source. It is forever sustainable and easily captured and converted. But now the technology may have taken yet another leap forward. To date the foundational technology behind photovoltaics was a structure called perovskite, which has been made with lead. Using tin instead of lead perovskite as the harvester of light, a team of Northwestern University researchers has created a new solar cell with "good efficiency". This good efficiency solar cell is low-cost, environmentally friendly and can be easily made using "bench" chemistry -- no fancy equipment or hazardous materials.
Spanish Island Powered by 100 Percent Renewable Energy

The possibilities of renewable energy are on display as El Hierro, the smallest of Spain’s Canary Islands, is set to become the world’s first land mass to be fully energy self-sufficient, when an 11.5 megawatt wind farm goes online late next month.
Bicycles Can Change the World
May 4, 2014 09:22 AM - Anna Brones, Care2
Saying that bicycles can change the world might sound like an oversimplification of things, but when you start to break it down, it’s easy to see that the bicycle has an effect on a lot more than just how we get from point A to point B. Need proof for why bicycles are a good way to change the world? Here are some good ones. 1. They provide alternative transportation It doesn’t take a scientist to work out that switching from four wheels to two wheels is a good thing. First there’s the environmental reason. For example, if 5 percent of people in New York commuting by car (either private or taxi) were to bike to work, they could save 150 million pounds of CO2 emissions per year. That’s the equivalent to the amount of CO2 reduced by planting a forest 1.3 times the size of Manhattan. And that’s only with a 5 percent change.
Is an Electric Car Right for You?
May 3, 2014 09:52 AM - CLEANTECHIES GUEST AUTHOR, Clean Techies
Operating a car without needing to visit a gas station is intriguing idea to many American drivers. After all, the pumps can be a painful place—gas prices have been on a roller coaster ride the past few years. But in the minds of many American, electric cars are nothing more than glorified golf cars incapable of providing adequate daily driving range or sufficient highway speed. In this new era of electrified transportation, those misconceptions need to be tossed aside. Todays' electric vehicles, like the Nissan Leaf, provide all the creature comforts and capabilities of gasoline internal combustion cars. These EVs comfortably seat four or five passengers, offer quasi-luxury features, and serve up smooth, silent and sporty levels of acceleration. But there are a couple of important issues to consider—such as driving range and refueling times.
Local residents chronicle lake water quality

Long-term water quality trends in Midwestern lakes yield good news in the form of little change in water clarity in the regions 3,000 lakes. But what makes this news unique is that the data to make this determination was collected by non-scientists and local residents from the area’s towns and villages.
First Standardized Global Land Cover Map Released
May 2, 2014 08:10 AM - Giovanni Sabato, SciDevNet
The first map of detailed information on worldwide land cover collected using uniform international standards, the Global Land Cover-SHARE database, was released in March by the UN Food and Agriculture Organization (FAO). Experts say it will help to improve research into natural resources and monitor global environmental changes.
Thoughtfully green Mother's Day gifts for your mother and Mother Nature
May 1, 2014 03:11 PM - Editor, ENN
No one is more special that your own mother - especially on Mother's Day. Celebrate your own mother and "Mother Nature" with one of these five great green gift ideas. These options offer a sustainable alternative to the chemical-laden flowers and mass-produced chocolates that dominate the market on Mother's Day. 1. Buy eco-friendly flowers- Although they are a beautiful part of nature, flowers aren't always eco-friendly. Most flowers are grown with a slew of chemicals and pesticides. They also typically come from warmer climates, such as South America, and have to make a long temperature-controlled journey before they reach your door. Opt for a greener option instead. There are several companies that sell eco-friendly flowers that are organically and locally grown. You could also purchase a potted plant from your local nursery. Not only are potted plants greener, they typically last a lot longer than a fresh-cut bouquet.
Oil underpinnings in Virunga National Park

Virunga National Park, classified as a World Heritage site sits amongst the Rwenzori Mountains on the eastern portion of the Democratic Republic of the Congo (DRC). It spectacular features include its most well known residents, hippos and mountain gorillas. It is believed to have more biological diversity than any other protected area in Africa, no doubt in large part due to its mountain forests, wetlands, savanna grassland, volcanoes and lakes.
