Reliant is bringing customers a unique electricity plan featuring an innovative learning thermostat to help manage home electricity use.
In a study that could solidify the trend toward construction of gigantic windmills, scientists have concluded that the larger the wind turbine, the greener the electricity it produces.
Renewable energy sources in the U.S. could supply 80 percent of electricity demand in 2050 just by using technologies commercially available today, according to a new study.
Geostellar, providers of advanced geomatic technology to accurately determine the value of solar energy generation for property owners, has announced an investment from strategic, financial and economic development sources including NRG Energy, Inc., GeoEye, Inc., the State of Maryland and Flash Forward Ventures.
A research team at the Freiburg Materials Research Center (FMF) led by the chemist Prof. Dr. Ingo Krossing has now developed a new system for producing methanol that uses CO2 and hydrogen. Methanol can, for example, be used as an environmentally friendly alternative for gasoline.
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.
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.
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.
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.
