Which type of energy will be the cheapest source of power?
February 24, 2015 08:57 AM - ClickGreen Staff, ClickGreen

Solar energy plants will soon deliver the most inexpensive power available in many parts of the world within a decade, according to a new analysis of the levelized cost of electricity (LCOE). By 2025, the cost of producing solar power in the UK will have declined to between 4.2 and 10.3 pence per kilowatt hour (p/kWh), and by 2050 to as low as 2.0 to 7.4 p/kWh, according to a study by the Fraunhofer Institute for Solar Energy Systems commissioned by Agora Energiewende.

Putting a value on forests
February 23, 2015 07:00 AM - Kaz Janowski, SciDevNet

The day I first set foot in a tropical rainforest, in Malaysia in the early 1980s, I experienced something profound. From the echoes of gibbons calling from the canopy in the early morning mist to the iridescent flash of a bird in a beam of sunlight, rainforests are a sensory delight as well as a marvel to anyone’s scientific curiosity. 

As I subsequently watched these forests dwindle and, in some cases, vanish, I have felt an equally profound sense of loss and a nagging guilt that I was somehow part of the story, because I had done little to remedy the situation. 
 

We need to focus on health and well-being, not economic growth
February 22, 2015 08:02 AM - Jules Pretty, Ecologist

The financial cost of the diseases of modern civilization is almost double the budget of the National Health Service, writes Jules Pretty, while the economy has grown past the point of greatest satisfaction. Our over-riding priority should be to move to greener, healthier, more sustainable and satisfying ways of life.

A substantial financial dividend could be released by a greener and healthier economy. Instead of encouraging material growth and consumption, we should consume in a way that is environmentally sustainable. 

The best-and worst-places to drive your electric car
February 20, 2015 03:47 PM - Nsikan Akpan, Science/AAAS

For those tired of winter, you’re not alone. Electric cars hate the cold, too. Researchers have conducted the first investigation into how electric vehicles fare in different U.S. climates. The verdict: Electric car buyers in the chilly Midwest and sizzling Southwest get less bang for their buck, where poor energy efficiency and coal power plants unite to turn electric vehicles into bigger polluters. Scientists at Carnegie Mellon University (CMU) in Pittsburgh, Pennsylvania, began their research by pulling public data from FleetCarma, a company that tracks vehicle performance among car fleets operated by governments and businesses. 

ENERGY STAR now certifies Clothes Dryers
February 20, 2015 09:53 AM - Editor, ENN

For the first time, ENERGY STAR is certifying clothes dryers. Starting this past President’s Day weekend, 45 models of ENERGY STAR certified dryers, from five different manufacturers, were available in stores nationwide. ENERGY STAR certified dryers include gas, electric and compact models, and incorporate innovative energy saving technologies, such as moisture sensors that detect when clothes are dry and automatically shut the dryer off. Dryers use more energy than any other appliance in the home, and since 80 percent of American homes own dryers, the savings potential is huge. With over 5 million dryers being soil last year, the new certified clothes dryers represent a great new opportunity for energy savings in the U.S.

Going Tubeless
February 19, 2015 09:09 AM - Catherine Gill, Care2

Recently one of the country’s most popular paper goods suppliers, Scott Products, did away with the cardboard inner tube inside of its toilet paper rolls and is now going tubeless. Here’s why that’s good news for the environment. Each year over 17 billion toilet paper tubes are thrown away, and most end up in landfills. To put that in perspective, this amount of waste is enough to fill the Empire State Building…twice! And did you know that in New York City alone, 14,000 toilet paper inner tubes are thrown away every 15 minutes? 

The effects of Global warming on fisheries assessed in new study
February 19, 2015 06:35 AM - Oregon State University

A report to be published Thursday in the journal Nature suggests that global warming may increase upwelling in several ocean current systems around the world by the end of this century, especially at high latitudes, and will cause major changes in marine biodiversity.

Since upwelling of colder, nutrient-rich water is a driving force behind marine productivity, one possibility may be enhancement of some of the world’s most important fisheries.

However, solar heating due to greenhouse warming may also increase the persistence of “stratification,” or the horizontal layering of ocean water of different temperatures. The result could be a warm, near-surface layer and a deep, cold layer.

Plant turns cow manure to ethanol
February 11, 2015 07:53 AM - Leon Kaye , Triple Pundit

Tulare County, California, recently surpassed nearby Fresno County as the top agriculture-producing county in terms of economic value within the U.S. It’s also the country’s top dairy producing county. The result has been more investment and economic growth in a rapidly booming area already home to 450,000 people.

But there is also a downside to the local dairy industry’s continued surge: The San Joaquin Valley suffers from some of worst air pollution in the U.S., and cow effluent is a threat to the region’s already troubled watersheds.

Why you should throw out your old TV
February 6, 2015 02:44 PM - Nsikan Akpan, Science/AAAS

We may think we’re a culture that ditches our worn technology at the first sight of something shiny and new, but a new study reveals that we keep using our old gadgets well after they go out of style. That’s bad news for the environment—and our wallets—as these outdated devices suck up much more energy than their newer counterparts.
