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.
Intense development of the two largest natural gas fields in the continental United States is driving away some wildlife from their traditional wintering grounds, according to a study by the Wildlife Conservation Society.
Every day, about 200 dogs and their owners visit the Cosmo dog park in Gilbert, Ariz. When they go home, they leave behind about eight cubic yards of dog waste, plastic bottles, bags and other trash.
Normally, all of that junk ends up in a landfill. But starting this month, the little gifts that Fido leaves will be used to power a light at the park, thanks to a team of engineering and technology students from ASU’s Polytechnic campus.
Most energy experts agree that cheap, clean, renewable wind energy holds great potential to help the world satisfy energy needs while reducing harmful greenhouse gases. But how can fluctuating wind power be made more consistent to match our power needs?
Forty years after a multi-year bi-partisan government commission recommended slowing U.S. population growth and eventually stabilizing, Americans still would like to see it happen, according to poll results to be released this weekend at the 2012 Earth Day Dallas festival.
U.S. commercial building owners could save an average of 38 percent on their heating and cooling bills if they installed a handful of energy efficiency controls that make their heating, ventilation and air conditioning, also known as HVAC, systems more energy efficient, according to a recent report from the Department of Energy's Pacific Northwest National Laboratory.
Harnessing the energy of sunlight can be as simple as tuning the optical and electronic properties of metal oxides at the atomic level by making an artificial crystal or super-lattice ‘sandwich,’ says a Binghamton University researcher in a new study published in the journal Physical Review B.
Colorado State University apparel design and production researchers and students are working to develop natural-fiber outdoor clothing that can charge MP3 devices, tablets, computers, GPS units and cell phones with built-in -- but comfortable to wear -- solar panels. The project is so impressive that it was recently selected to compete in a sustainability design competition in Washington, D.C., from April 21-23.
By the end of 2011, the nearly 16,500 Energy Star certified buildings across America have helped save nearly $2.3 billion in annual utility bills and prevent greenhouse gas emissions equal to emissions from the annual energy use of more than 1.5 million homes.
The U.S. Army is leading the march for renewable energy with a goal of 25 percent clean power by 2025. The Army Corps of Engineers has set up the Energy Initiatives Task Force (EITF) as of September, 2011 to help meet the deadline.

Producing hydrogen from non-fossil fuel sources is a problem that continues to elude many scientists but University of Delaware’s Erik Koepf thinks he may have discovered a solution.
Solving server overheating problems at datacenters will save massive amounts of wasted energy worldwide.
Survey of Over 100 Solar Manufacturers Reveal Current Environmental, Worker Safety, and Fiduciary Considerations
Achievable standard is in line with investments already being made and will inform the building of new plants moving forward.
Last March, the world watched closely as Japan struggled to contain a series of equipment failures, hydrogen explosions and releases of radioactive materials at the Fukushima Daiichi Nuclear Power Plant.
As scientists continue the hunt for energy sources that are safer, cleaner alternatives to fossil fuel, an ever-increasing amount of valuable farmland is being used to produce bioethanol, a source of transportation fuel. And while land-bound sources are renewable, economists and ecologists fear that diverting crops to produce fuel will limit food resources and drive up costs.
