The Tesla Model S
May 24, 2013 02:04 PM - ERIC NIILER, DiscoveryNews
The new all-electric Tesla S sedan is not just the favorite of car magazines, now Consumer Reports calls it the best car they’ve ever driven, scoring 99 points of 100 and beating out the Lexus LS460 that held the previous record back in 2007. What does this massive battery-powered EV have that no others do? "It handles like a sports car, it rides like a luxury car, it has the energy efficiency that is twice as good as the best hybrids and is the quietest car we’ve ever tested," said CR tester Gabe Shenhar. "It does so many things so right on so many levels that to us it wasn't a surprise." Perhaps that's why Tesla Motors has sold more cars during the first quarter of 2013 than luxury German automakers, Mercedes-Benz, BMW and Audi, prompting the Palo Alto-based firm to declare its first-ever profit and raise expected sales for 2013 from 20,000 to 21,000.
Memorial Day Travel will Cost Americans over $1 Billion on Gasoline
May 24, 2013 10:48 AM - Allison Winter, ENN
Memorial Day not only marks the day we pay tribute to those who have served in the United States Armed Forces, but it also marks the first unofficial weekend that kicks off the summer. With that said, tens of millions of Americans are expected to get away this weekend and according to an analysis by the Union of Concerned Scientists (UCS), Americans will spend more than $1.4 billion filling up their tanks! The new analysis utilizes newly released data from the American Automotive Association (AAA), which estimated that 89 percent of Memorial Day weekend travelers (about 31.2 million Americans) will travel by vehicle.
Free Range Milk?
May 24, 2013 06:17 AM - Lorna Howarth, The Ecologist
Free-Range Dairy is a new initiative that could reverse the trend towards industrialised mega-farms. The Ecologist office is set in an Area of Outstanding Natural Beauty within a United Nations Biosphere Reserve. Hartland peninsular is dotted with steep, wooded valleys where bluebells, early purple orchids and woodpeckers abound.The hills afford breathtaking views across the Bristol channel to Lundy Island, itself a nature reserve with a no-fish zone that is having a beneficial effect on marine ecology, and looking south-west down to Cornwall, on a clear day, one can see to Boscastle and Bodmin moor beyond. But something is missing from this bucolic scene - one notices it first whilst walking the country lanes on a warm spring evening. There is no rhythmic munching of grass on the other side of the hedge; no bovine belching or contented sighing as the cows enjoy the sun on their backs after a long winter in the cattle yard. For here in Hartland, as elsewhere in the country, the trend is towards carbon-intensive, 'industrialised' farming where huge herds of 1,000 cows or more are kept indoors all year long, with only a concrete yard for exercise.

Most home thermostats contain a few grams of mercury. Although they only contain small quantities of mercury and do not by themselves exceed any regulatory threshold, they contain enough mercury to potentially cause a significant health risk. The state of California has issued new rules that will greatly reduce the amount of dangerous mercury sent to landfills and incinerators each year due to the improper disposal of old mercury-laden thermostats. The new rules will require thermostat manufacturers to collect and recycle the vast majority of discarded mercury thermostats in California. Over the next five years, this will keep nearly 2 tons of the toxin out of garbage trucks, landfills and incinerators where the mercury can be released from crushing or burning, according to the Natural Resources Defense Council, the California Product Stewardship Council, and the California Sierra Club.
African soil diversity mapped for the first time
May 22, 2013 10:19 AM - Bernard Appiah, SciDevNet
A team of international experts has drawn up the Soil Atlas of Africa — the first such book mapping this key natural resource — to help farmers, land managers and policymakers understand the diversity and importance of soil and the need to manage it through sustainable use. They say that despite soil's importance, most people in Africa lack knowledge about it, partly because information about it tends to be confined to academic publications read only by scientists.
Texas Legislature Passes Commercial and Industrial PACE Bill
May 21, 2013 01:29 PM - Editor, Clean Techies
The Texas House and Senate passed Senate Bill 385 in May. If Governor Rick Perry approves the bill, the state will break new ground by developing plans for commercial and industrial property assessed clean energy (PACE) programs. This bill will redesign Texas's approach to PACE, focusing on the commercial and industrial sectors rather than on residential programs. The legislation covers both energy efficiency and water efficiency. To facilitate local decision making, cities and local areas will partner with businesses and nonprofits to set up their own PACE programs. These programs will allow businesses to borrow money from private lenders and repay it yearly via an assessment on their property taxes.
Aquifers in US Depleting, Contributing to Sea-Level Rise
May 21, 2013 10:24 AM - Allison Winter, ENN
The High Plains (also known as Ogallala) aquifer underlies more than 170,000 square miles of the United States. Aquifers are water storage areas that are made up of bodies of permeable rock that contain and transmit groundwater. The High Plains aquifer serves as the principal source of water for irrigation and drinking in the Great Plains, serving over two million people. However, substantial pumping of the aquifer for irrigation since the 1940s has resulted in large water-table declines. Depleting aquifers of groundwater can lead to serious consequences as pumping water out of the ground faster than it can be replenished can permanently dry up wells, reduce water in lakes and streams, and deteriorate water quality.
Fishing the Gulf of Maine: Tradition at a Crossroads
May 20, 2013 11:41 AM - Michael Sanders, The Ecologist
Lobster fishing remains big business off the coast of Maine but even with new regulations and new gadgets can it ever be sustainable? Michael Sanders investigates the real costs of the crustacean on your plate... When most of us go down to the coast, whether to walk or swim or fish or sail, we take for granted what we see before us. We see the lobster boats and the colorful buoys marking the strings of traps, the bobbing green and red cans marking safe passage, the gulls and other seabirds. In the larger working harbors like Portland and Stonington and Port Clyde, there might be draggers tied up, unloading fish they've caught far out in the Gulf of Maine and on Georges Bank. What we don't realize is that this seemingly unchanging marine world is in fact always changing in ways both large and small. What we think of as "the coast of Maine" - those 3,000 vaunted miles of rocky shoreline punctuated by seaside villages and docks and lobster pounds and fishing fleets - was largely built on the backs of the fishermen and lobstermen who are there, however picturesque or authentic to the eye, for a single purpose: to harvest the sea in order to feed us.
Want to benefit wildlife? Let land go untended.
May 20, 2013 06:02 AM - Roger Greenway, ENN
Which environment would wildlife prefer, actively farmed and managed land, or untended natural land that to us might appear unkempt? Turns out that parts of the farm landscape that look overgrown and 'scruffy' are more important in supporting wildlife than they first appear, according to new research published today in Ecology Letters. The findings stem from an intensive study of an organic farm in Somerset by a team of scientists focussing on the complex ways in which animals and plants interact. First, the team of researchers from the University of Hull, the University of Bristol and the Centre for Ecology & Hydrology, created one of the world's largest terrestrial food-webs — a what-eats-what guide to the food-chain, and then developed a method of predicting what would happen to the whole food-web when habitats were lost.
Drought and Desertification - Global Response
May 19, 2013 09:11 AM - ANDREW BURGER, Global Warming is Real
Land degradation — more specifically drought and desertification — have become increasingly pressing problems for a growing number of countries around the world, threatening efforts to alleviate poverty, improve basic health and sanitation and address socioeconomic inequality, as well as spur agricultural and sustainable economic development. The only multilateral, international agreement linking development and environment to sustainable land management (SLM), high-level representatives from 195 nations will be gathering in Windhoek, Namibia from September 16-27 for the 11th bi-annual Conference of Parties (COP) to review implementation of the United Nations Convention to Combat Desertification (UNCCD). Meeting for the first time in southern Africa, UNCCD delegates will review implementation of the convention to date and plan for the ensuing two years of programs and actions.
