Renewable energy technologies generally consist of two distinct processes: energy generation (using sources such as coal, solar, wind, etc.) and energy storage (such as batteries).
Earlier this year the Raleigh Police Department installed mobile power idle reduction systems in 29 police vehicles. The project was funded by an Energy Efficiency and Conservation Block Grant, and aligns with Raleigh's commitment to environmental protection outlined in the City's Comprehensive Plan.
Engineers at Oregon State University have made a breakthrough in the performance of microbial fuel cells that can produce electricity directly from wastewater, opening the door to a future in which waste treatment plants not only will power themselves, but will sell excess electricity.
Researchers may have discovered a new method to predict solar flares more than a day before they occur, providing advance warning to help protect satellites, power grids and astronauts from potentially dangerous radiation.
Two researchers have reprised in the journal Energy Policy their groundbreaking finding that improvements in lighting — from candles to gas lamps to electric bulbs — historically have led to increased light consumption rather than lower overall energy use by society.
Stony Brook University scientists have found that the disposal of contaminated wastewater from hydraulic fracturing – commonly known as “fracking” – wells producing natural gas in the Marcellus Shale region poses substantial potential risks of river and other water pollution that suggests additional regulation to reduce the potential of drinking water contamination.
In some isolated clinics in parts of Africa, the electricity needed to power lights and medical devices is generated by expensive imported diesel fuel; the water supply can be so cold in winter that health workers can’t even wash their hands properly. But a startup company established by a team of MIT students and alumni aims to change that.
The popularity of fluorescent lamps and compact fluorescent lamps (CFLs) is steadily growing in the industrial, commercial and residential markets. However, they can also be potentially dangerous because of their mercury content.
U.S. proved crude oil and natural gas reserves achieved record annual volumetric increases in 2010 according to U.S. Crude Oil, Natural Gas, and Natural Gas Liquids Proved Reserves, 2010, released today by the U.S. Energy Information Administration (EIA).
Led by Sri Narayan, professor of chemistry at the USC Dornsife College of Letters, Arts and Sciences, the team developed an air-breathing battery that uses the chemical energy generated by the oxidation of iron plates that are exposed to the oxygen in the air – a process similar to rusting.
A new versatile measurement system devised by researchers at the National Institute of Standards and Technology (NIST) accurately and quickly measures the electric power output of solar energy devices, capabilities useful to researchers and manufacturers working to develop and make next-generation solar energy cells.
Today, the U.S. Environmental Protection Agency’s (EPA) Energy Star program launched the 2012 National Building Competition: Battle of the Buildings with a record 3,200 buildings across the country going head to head to improve energy efficiency, lower utility costs and protect health and the environment.
Last week’s record of the fastest ever manned electric aircraft was set by electric-vehicle record-setter Chip Yates.
There’s a lot of moaning and hand-wringing whenever gasoline prices approach $4 a gallon. But all it would take for them to hit $10 a gallon overnight would be hurricanes wiping out a couple of refineries or saboteurs disabling a couple of pipelines, says Dr. R. Paul Williamson, founder and CEO of the non-profit Sustainable Systems of Colorado.
Inspired by a European study, a team of Stony Brook University researchers looked into the potential impact of healthy human skin tissue (in vitro) being exposed to ultraviolet rays emitted from compact fluorescent light (CFL) bulbs.
Maersk Line reports it has saved almost $90 million since 2009 by using Key Performance Indicators (KPIs) to measure the performance of individual ships.
The U.S. Environmental Protection Agency has fined Calpine Corporation, owner of a 500-megawatt natural-gas fired power plant, $13,500 for the improper management of hazardous waste at its Yuba City, Calif. facility.
The U.S. Environmental Protection Agency (EPA), in partnership with the Georgia Force, collected Change the World with ENERGY STAR® pledges at the Georgia Force Arena Football game in the Gwinnett Arena in Duluth, GA.
A Michigan Technological University researcher has made a solar cell that brings more to the rooftop: it’s good at making electricity, and it’s great at capturing heat to warm your home and your water.
The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice (DOJ) announced a Clean Air Act (CAA) settlement with Dairyland Power Cooperative (DPC) that will cover the utility’s three power plants in Alma and Genoa, Wis.
