World Environment Day
June 2, 2011 01:31 PM - Andy Soos, ENN

World Environment Day is a day that is supposed to stimulate awareness of the environment and enhance political attention and public action. The official day is June 5. This was the day that the United Nations Conference on the Human Environment began. The first World Environment Day was on 1973. The theme this year is Forests-Nature At Your Service. Forests cover one third of the earth’s land mass, performing vital functions and services around the world which make our planet alive with possibilities. In fact, 1.6 billion people depend on forests for their livelihoods. They play a key role in the world ecology, releasing oxygen into the atmosphere while storing carbon dioxide. Thousands of activities are typically organized worldwide, with beach clean-ups, concerts, exhibits, film festivals, community events and much more. Each year there is a different host city. For 2011 it is New Delhi, India.

June 2, 2011 09:54 AM - David A Gabel, ENN

In one of the state's most bizarre weather events, Massachusetts was hit by several tornadoes yesterday, causing destruction, injuries, and the deaths of at least four people. The tornadoes occurred in several towns in the Springfield area including Westfield, West Springfield, Wilbraham, Sturbridge, Monson, Oxford, Charlton, Agawam, Brimfield, and Douglas. Massachusetts residents have been shocked by the extensive damage left in their wake.

Algae Treatment
June 1, 2011 09:44 AM - Andy Soos, ENN

It is like the Goldilocks fable. Too much algae chokes up an ecosystem. Too much nutrients can cause excessive biological growth. The just right amount of algae can balance the system just right. An article published in the June issue of BioScience describes the early scale-up stage of a new biotechnology with environmental benefits and possible commercial potential. Algal turf scrubbers are field-sized, water-treatment systems that can extract excess nutrients from streams, canals, and lakes polluted by agricultural, domestic, and some industrial runoff. They use sunlight as their principal source of energy and simultaneously restore oxygen levels. The devices work by pulsing contaminated water across algae that are allowed to grow on screens. algal turf scrubbers produce waste suitable for use as a nitrogen- and phosphorus-rich fertilizer and for conversion to biofuel or high-value nutraceuticals. Some algal turf scrubbers can even operate in open water, thus minimizing loss of agricultural land to the systems.

How to Bring Electric Vehicles to the Mass Market
June 1, 2011 09:41 AM - David A Gabel, ENN

Electric cars are not a new concept in the automotive industry. They were around before the pre-eminence of the internal combustion engine in the 1890s. They were introduced again in the United States in the 1990s with GM's EV1, but were dropped when GM decided they are unprofitable. Now the Chevy Volt is out and several more models will be hitting the market soon. Automakers must figure out how to avoid having their electric vehicles suffer an agonizing death in the niche market, and instead, figure out how to get 100 million EVs on the road.

Mammoth Mating Habits
May 31, 2011 08:23 AM - Andy Soos, ENN

Like their modern relative the elephant, mammoths were quite large. The largest known species, Songhua River mammoth, reached heights of at least 16 feet at the shoulder. Mammoths would probably normally weigh in the region of 6 to 8 tons, but exceptionally large males may have exceeded 12 tons. However, most species of mammoth were only about as large as a modern Asian elephant. A DNA-based study sheds new light on the complex evolutionary history of the woolly mammoth, suggesting it mated with a completely different and much larger species. The research, which appears in the biomed Central's open access journal Genome Biology, found the woolly mammoth, which lived in the cold climate of the Arctic tundra, interbred with the Columbian mammoth, which preferred the more temperate regions of North America and was some 25 per cent larger.

Can OnStar Help Chevy Sell the Volt and Utilities Manage the Load?
May 29, 2011 09:29 AM - Matthew Madden , Triple Pundit

Can the combination of electric vehicles and software services return General Motors to relevance? Two decades after the introduction of the EV1, not to mention the subsequent controversy created by its cancelation — well documented by the film that became an underground sensation Who Killed the Electric Car? — the Chevrolet Volt is General Motors' latest entrant into the electric vehicle market. While the Volt may get the bulk of the press, the software services that support the automobile may be the business that allows General Motors to compete in the next generation of automotive innovation. OnStar, a subsidiary of General Motors, has garnered success by providing communications and mobility services, security, remote diagnostics and navigation by subscription to drivers of General Motors’ vehicles. The trend towards software-enabled functionality has been guiding automotive development in recent years but the imminent adoption of electric vehicles necessitates the advancement of this functionality. OnStar, and by extension General Motors, may be well positioned to capitalize on this emerging market.

Wind in 2011
May 27, 2011 11:00 AM - Andy Soos, ENN

Some people like the concept of wind/renewable power. There are some who do not. Nevertheless society needs energy to run its desired lifestyle. So how are we in 2011 so far? The AWEA (American Wind Energy Association) indicated that the first quarter of 2011 saw over 1,100 megawatts (MW) of wind power capacity installed -- more than double the capacity installed in the first quarter of 2010. The U.S. wind industry had 40,181 MW of wind power capacity installed at the end of 2010, with 5,116 MW installed in 2010 alone. The U.S. wind industry has added over 35% of all new generating capacity over the past 4 years, second only to natural gas, and more than nuclear and coal combined. Today, U.S. wind power capacity represents more than 20% of the world’s installed wind power. Today, the U.S. wind industry represents not only a large market for wind power capacity installations, but also a growing market for American manufacturing. Over 400 manufacturing facilities across the U.S. make components for wind turbines, and dedicated wind facilities that manufacture major components such as towers, blades and assembled nacelles can be found in every region.

Fuel Economy Labels by EPA
May 26, 2011 01:15 PM - Andy Soos, ENN

What car is better at least in terms of fuel use, costs and environmental benefits. The decision will never be simple. The U.S. Department of Transportation and the U.S. Environmental Protection Agency have released new fuel economy labels that will help consumers take advantage of the increased efficiency standards achieved under the Obama Administration. The new labels, which are the most dramatic overhaul to fuel economy labels since the program began more than 30 years ago, will provide more comprehensive fuel efficiency information, including estimated annual fuel costs, savings, as well as information on each vehicle’s environmental impact. These improvements will give consumers better, more complete information to consider when purchasing new vehicles that are covered by the increased fuel economy standards. Starting with model year 2013, the improved fuel economy labels will be required to be affixed to all new passenger cars and trucks — both conventional gasoline powered and “next generation” cars, such as plug-in hybrids and electric vehicles

Coffee and Prostate Cancer
May 25, 2011 04:51 PM - Andy Soos, ENN

Coffee is a brewed drink prepared from roasted seeds, called coffee beans, of the coffee plant. Coffee beans are found in coffee cherries, which grow on trees in over 70 countries, cultivated primarily in Latin America, Southeast Asia, and Africa. Findings have historically been contradictory as to whether coffee has any specific health benefits, and results are similarly conflicting regarding the potentially harmful effects of coffee consumption. Men who regularly drink coffee appear to have a lower risk of developing a lethal form of prostate cancer, according to a new study led by Harvard School of Public Health (HSPH) researchers. The lower risk was evident among men who drank regular or decaffeinated coffee.

Waste Heat Recovery: The Next Wave of Clean Tech
May 24, 2011 03:32 PM - Jason Gold, CEO, KGRA Energy, LP

The terms renewable energy and clean technology conjure up images of photovoltaic panels baking in the desert sun, wind turbines rotating lazily in the wind, and large dams generating hydro-power. However, there is another important and growing clean energy technology that the average consumer hasn't heard of yet: waste heat recovery. Waste heat recovery employs a process that has been around since the 1960s called the organic Rankine cycle (ORC), which easily integrates into existing manufacturing infrastructures. ORC units capture heat that is currently being released into the atmosphere and converts it into useable CO2-free electricity. This technology has a small footprint, approximately the size of a tractor trailer flatbed and interest in systems that use this energy generating skid is on the rise as companies look to maximize the efficiency of existing investments and infrastructures. The market for waste heat recovery is virtually limitless. According to researchers at University California Berkley, the U.S. currently consumes about 100 quadrillion BTUs of energy per year. However, between 55 and 60 quadrillion BTUs are currently vented into the atmosphere as waste heat. With ORC technology these emissions are harnessed on-site to generate useable CO2-free electricity that is fed directly back into a manufacturing process. Pulp and paper, lumber, refinery, cement and power plant operations are especially well-suited for waste heat recovery systems since they consume large amounts of electricity and maintain consistent waste heat streams with temperatures between 400° and 800°F.
