LED Bulb Challenge ending soon!
April 9, 2014 01:34 PM - ENN Staff
The most inefficient light bulbs may now be off the market, in response to new federal standards, but nearly 70% of light bulb sockets in the U.S. still contain an inefficient bulb. Retailers across the country are stepping up to help change that, as part of the Energy Star LED Bulb Challenge.
At more than 23,000 feet, why don't bar-headed geese get hypoxic?
April 9, 2014 10:04 AM - ENN Staff
The bar-headed goose migratory path takes it over the Himalayan Mountains each year between China and Mongolia to their Indian breeding grounds. This flight path puts them at 23,917 feet above sea level. University of Exeter led study followed these birds to gain insight into their ability to survive these extreme altitudes in hopes that their findings might have future implications for low oxygen medical conditions in humans.
High Tech Trees!
April 8, 2014 01:20 PM - ENN Staff
Scientists at Oregon State University have found a way to convert tree cellulose into high-tech energy storage devices. Because cellulose is a key component of trees and the most abundant organic polymer on earth this discovery will have a profound impact in industry. Scientists were able to heat the tree cellulose in a furnace in the presence of ammonia to create the building block for supercapacitors for use in industrial electronic applications. Supercapacitors are extraordinarily, high-power energy devices for which production has been held back by cost and difficulty in producing high-quality carbon electrodes.
Desert absorption helps curtail CO2 levels
April 7, 2014 09:55 AM - Eric Sorensen, Washington State University News
Researchers led by a Washington State University biologist have found that arid areas, among the biggest ecosystems on the planet, take up an unexpectedly large amount of carbon as levels of carbon dioxide increase in the atmosphere. The findings give scientists a better handle on the earth's carbon budget — how much carbon remains in the atmosphere as CO2, contributing to global warming, and how much gets stored in the land or ocean in other carbon-containing forms.
European Union Gets 23.4% of Electricity From Renewables
April 4, 2014 08:03 AM - Edouard Stenger, Clean Techies
According to official statistics from Eurobserv’ER, 23.4 percent of the electricity in the European Union came from renewable energy sources in 2012. The total output for 2012 has been estimated at 763.5 TW. This represents an important increase from 2011, when these energy sources brought "only" 20.4 percent of total electricity.

Climate change has been a constant reality for many Filipinos, with impacts ranging from extreme weather events to periodic droughts and food scarcity. The most affected populations are coastal residents and rural communities that lack proper disaster preparedness.
American's energy usage jumps in 2013
April 2, 2014 01:08 PM - ENN Staff
Despite many individual efforts to decrease energy usage for 2013 increased by 2.3 Quadrillion thermal units over the previous year. These statistics have been monitored and presented by the Lawrence Livermore National Laboratory (LLNL) in the most recent energy flow charts measuring renewable, fossil and even nuclear energy.
IPCC warns over greater risk to food and water security
April 2, 2014 10:38 AM - F.Fiondella/IRI/CCAFS, SciDevNet
[NEW DELHI] The climate change-related risks from extreme events such as floods and heat waves will rise further with global warming, aggravating food and water insecurity, especially for some of the poorest communities, says the second instalment of the latest UN Intergovernmental Panel on Climate Change (IPCC) report.
Seaweed forests could help power tropical islands
April 1, 2014 06:45 AM - Jan Piotrowski, SciDevNet
Harvesting seaweed 'forests' and feeding them into large underwater digesters could one day meet the world's energy needs, with nine per cent of the ocean floor being enough to replace fossil fuels entirely, according to an ambitious idea. Even a more immediate and realistic use of seaweed — a major untapped resource — would greatly increase the self-sufficiency and sustainability of small island states, but limited investment is preventing the roll-out of relevant technologies, marine biofuel experts have said.
Desalination is Now a Billion Dollar Industry, Report Shows
March 31, 2014 08:07 AM - Phil Covington, Triple Pundit
Despite some early March rain in California, and a few storm systems moving in this week, the late season moisture will sadly fall far short of that which is needed to pull the state out of its four-year drought.
