Saving money with wasted heat
April 18, 2014 08:18 AM - Megan Fellman, Northwestern University
Nearly two-thirds of energy input is lost as waste heat. Now Northwestern University scientists have discovered a surprising material that is the best in the world at converting waste heat to useful electricity. This outstanding property could be exploited in solid-state thermoelectric devices in a variety of industries, with potentially enormous energy savings.
Scenario development yields environmental success story
April 17, 2014 03:37 PM - Robin Blackstone, ENN
With so much scenario modeling currently available, we are able to better predict our future and anticipate the outcomes of various habits and activities. While invaluable in the area of prediction, how has that information transformed our environmental status? Is our environmental future optimistic or dismal? Will we be able to celebrate Earth Day in the future knowing that we have responded appropriately to the bleak prophecies?
Human Life Expectancy Linked to Extinctions
April 16, 2014 04:14 PM - Dominic Rowland, MONGABAY.COM
Since the arrival of Homo sapiens, other species have been going extinct at an unprecedented rate. Most scientists now agree that extinction rates are between 100 and 1000 times greater than before humans existed. Working out what is driving these extinctions is fiendishly complicated, but a new study by scientists from the University of California, Davis and the Nebraska Cooperative Fish and Wildlife Research Unit suggests that human life expectancy may be partly to blame.
Electric car numbers double in one year
April 16, 2014 09:10 AM - Editor, The Ecologist
There are now more than 400,000 electric cars on the world's roads - twice as many as a year ago, and on current trends there will be a million by 2016. Leading the market are the USA, Japan and China - while Europe trails behind. The number of electrically powered automobiles worldwide climbed to just over 400,000 in early 2014. This figure was determined in an analysis conducted by the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW).
Weather throws a curve
April 16, 2014 07:14 AM - Robin Blackstone, ENN
Apparently the intense curve of the jet stream can predict the variability of an entire season and it is part of a 4,000 year pattern. Last winter's curvy jet stream in North America resulted in mild western temperatures and harsher cold temperatures in the east. University of Utah researchers reveal that a similar pattern became more pronounced 4,000 years ago, suggesting that it may worsen as Earth's climate warms.
Electricity Prices Fall In Europe As German Renewable Energy Output Increases
April 15, 2014 01:18 PM - Gina-Marie Cheeseman, Triple Pundit
For the fifth consecutive month, electricity prices in countries neighboring Germany have decreased, recently released Platts data reveals, due in large part to increased solar and wind generation in Germany.
IPCC concludes: Renewable energy shift is a must
April 15, 2014 10:34 AM - ENN Editor
Conclusions from the Intergovernmental Panel on Climate Change's are simple: rapid shifts to renewable energy are needed to avert catastrophic global warming. The IPCC's report was produced by 1250 international experts and approved by each major government in the world. The report documented increases in human-caused greenhouse gases, the source of those gases, and their climatic effect. The most significant conclusions resulting from IPPC report are: - Current efforts to reduce greenhouse gases are not enough. - Energy supply is not the only thing driving emission increases. - Big changes will be needed to avoid disaster scenarios.
To bee or not to bee
April 15, 2014 09:33 AM - Staff, ClickGreen
Bumblebees are among the most loved and familiar of garden insects. The sight and sound of them buzzing from flower to flower is a quintessential part of summertime, but sadly these charismatic creatures are now struggling to survive. In our modern world of paved gardens and intensive agriculture our bumblebees find themselves hungry and homeless.
Climate Change: We have met the enemy and they are us
April 14, 2014 09:35 AM - ENN Editor
According to McGill University physics professor Shaun Lovejoy, we have no one to blame but ourselves for global warming in the industrial era. Lovejoy and his research team have just completed an analysis of temperature data covering more than 500 years. This study all but rules out the possibility that global warming is just a natural fluctuation in the earth's climate.
Ford to release electric Focus
April 13, 2014 08:01 AM - BOB SHETH, Electric Forum
Ford has already confirmed plans for a new 2015 Focus Sedan although the introduction of a Ford Focus Electric car in New York next week did take some experts by surprise. While the company has been relatively successful with regards to its alternative power supply vehicles, the introduction of the Focus Electric seems to be low key to say the least. The press release which accompanied next week’s launch did much to wax lyrical about the Ford Sedan but there was very little in the way of mention about the Ford Focus Electric. This has prompted speculation as to whether Ford has an "ace up its sleeve" or indeed whether it is playing down the electric car launch because it may well be a token gesture on the company's behalf?
