A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. The first-of-its-kind "pyroelectric nanogenerator" is the topic of a report in ACS' journal Nano Letters.
The use of composite materials is rapidly entering into the automotive industry thanks to a technique developed by the EPFL spin-off EELCEE. This technique promises lighter cars that burn less fuel and, consequently, emit less CO2.
Honeywell, a Fortune 100 technology and manufacturing company, has created a new building management system and Smart Grid Solutions business to help meet facilities' and providers' energy needs.
Chemical reactions on the surface of metal oxidesare important for applications such as solar cells that convert the sun's energy to electricity. Now scientists have found that a previously unappreciated aspect of those reactions could be key in developing more efficient energy systems.
A commentary published today in GCB Bioenergy reveals that calculations of greenhouse gas (GHGs) emissions from bioenergy production are neglecting crucial information that has led to the overestimation of the benefits of biofuels compared to fossil fuels.
University of Tennessee researchers have successfully developed a key technology in developing an experimental reactor that can demonstrate the feasibility of fusion energy for the power grid.
An EPA direct final rule published June 8 amends its heavy-duty diesel regulations so engine manufacturers may deploy emission controls or settings to be used only in emergency vehicles such as ambulances and fire trucks.
Leading environmental services company Republic Services, Inc., FORTISTAR and Duke Energy dedicated a new, state-of-the-art, landfill gas-to-energy plant in North Carolina with a ribbon-cutting event at the site today.
The Boeing Company has steadily reduced its environmental footprint while rapidly expanding its business and significantly increasing monthly airplane production rates, the company reported in its fifth annual Environment Report.
Boulder Ionics, a new startup, has apparently found a way to get more bang for the buck with lithium ion batteries by creating a liquid electrolyte out of ionic salts that performs better than anything else currently being used.
Higher water temperatures and reduced river flows in Europe and the United States in recent years have resulted in reduced production, or temporary shutdown, of several thermoelectric power plants, resulting in increased electricity prices and raising concerns about future energy security in a changing climate.
Individual homes and entire neighborhoods could be powered with a new, small-scale solid oxide fuel cell system that achieves up to 57 percent efficiency, significantly higher than the 30 to 50 percent efficiencies previously reported for other solid oxide fuel cell systems of its size.
Today, the U.S. Environmental Protection Agency (EPA) announced approximately $3.8 million in new pilot grants to nine recipients across the country for cleanup and redevelopment of contaminated properties. One of the grants will go to the City of Mt. Shasta, Calif.
Mid-America Pipeline Company, LLC (MAPCO), and Enterprise Products Operating LLC (Enterprise), of Houston, Texas, have agreed to pay a civil penalty of more than $1 million to the United States to settle violations of the federal Clean Water Act related to three natural gasoline pipeline spills in Iowa, Kansas and Nebraska.
Finding an efficient way to store solar energy is a major goal for science and society. Writing this week in the journal Angewandte Chemie, a Wisconsin group of researchers describes a new high-throughput method to identify electrocatalysts for water oxidation.
Starting on July 14, 2012, the Department of Energy (DOE) will begin phasing out most T12 fluorescent lights and replacing them with energy-efficient T5 lights. To help make the adjustment to T5 lights easier, one company in the United States has begun making retrofit plug-and-play adapters.

Average fuel economy (window-sticker values) of cars, light trucks, minivans and SUVs purchased in April was 23.9 mpg, down from 24.1 in March, but the same as in February. Despite the drop, fuel economy is up 3.8 mpg (or 19 percent) from October 2007, the first month of monitoring by UMTRI researchers Michael Sivak and Brandon Schoettle.
The Southeastern Pennsylvania Transportation Authority, the nation’s sixth-largest public transport organization, has signed a three-year contract with SourceOne energy consulting firm. SEPTA is looking for support for electricity and natural gas procurement.
Sculpted by chemistry graduate student Longzhu Shen (MCS'12), the latest installation at CMU's ArtPark Lab uses environmentally friendly lighting to illustrate the fluctuation of carbon dioxide levels in Earth's atmosphere over the past 800,000 years.
U.S. soldiers are increasingly weighed down by batteries to power weapons, detection devices and communications equipment. So the Army Research Laboratory has awarded a University of Utah-led consortium almost $15 million to use computer simulations to help design materials for lighter-weight, energy efficient devices and batteries.
