Preventing Home Energy Drain

There are energy vampires lurking in your home that are disguised as normal appliances and electronics. These bloodthirsty monsters have a voracious appetite for sucking energy out of your electrical outlets and money out of your wallet, even when they’re turned off or in sleep mode.[read more]

Here's Why Your Utility Bills Soar in Winter

Energy Bills in Winter

 

Opening a heating bill during the holiday season is worse than unraveling a string of twinkle lights. Since when does it cost more to heat a 600-square-foot apartment than it does to feed a family of eight? That may be an exaggeration, but I’m sure that’s how most of us feel during the winter months.[read more]

Don't Toss Out the Good Electricity with the Bad

Some electricity uses can reduce overall carbon emissions. Here are some options for EPA to consider to avoid inadvertently discouraging states from deploying electric vehicles, electric mass transit, and other technologies that use electricity instead of a dirtier fuel.[read more]

New Study: America's Data Centers Consuming, and Wasting, Growing Amounts of Energy

Data Centers and Energy Use

All of our online activity is delivered through nearly 3 million data centers across America, from small closets and larger server rooms, to mammoth “cloud” server farms. Their explosive growth is gulping huge amounts of energy, and despite some efficiency improvements much of it is still wasted.[read more]

Advanced Energy Technology of the Week: Combined Heat and Power (CHP)

Combined Heat and Power

Combined Heat and Power, also called cogeneration, generates both electricity and useful heat from the same fuel source. CHP typically involves dedicated equipment to generate electricity, followed by recovery of exhaust/waste heat for use in industrial processes, space heating, or water heating.[read more]

Running on Waste Heat

Waste Heat and Power

It’s estimated that more than half of U.S. energy — from vehicles and heavy equipment, for instance — is wasted as heat. Mostly, this waste heat simply escapes into the air. But that’s beginning to change, thanks to thermoelectric innovators such as MIT’s Gang Chen.[read more]

Bakken Shale Gas Flaring Highlights Global Problem

August 4, 2014 by Geoffrey Styles

The Wall St. Journal recently reported on the high rate at which excess natural gas from wells in North Dakota's Bakken shale formation is burned off, or "flared." The Journal cited state data indicating 10.3 billion cubic feet (BCF) of gas were flared there during April 2014.[read more]

Network-Connected Electronics Wasted the Equivalent of 133 Coal Plants Last Year

July 10, 2014 by Katherine Tweed

Device Electricity Waste

Last year, there was a missed opportunity to save the amount of energy produced by 133 mid-size coal-fired power plants. And it did not involve adjusting thermostats or turning off lights. Instead, the 400 terawatt-hours of wasted energy globally were sucked up by network-enabled devices.[read more]

Diagnosing 'Broken' Buildings to Make them Greener

June 24, 2014 by Energy @ MIT

Diagnosing Buildings

The co-founders of MIT spinout KGS Buildings have an important saying: “All buildings are broken.” The energy that is wasted through faulty or inefficient equipment, they say, can lead to hundreds of thousands of dollars in avoidable annual costs.[read more]

Microbes Chow Down on Latest Fuel-Cell Tech

May 31, 2014 by Energy @ MIT

Microbes and Fuel-Cell Innovation

You can very quickly run out of fingers and toes in counting the myriad ways we waste energy. Take the inefficiency of our sewage systems, for example: The energetic content of wastewater is about 10 times the amount of energy it takes to process it.[read more]

Warm Weather Ways to Cut Energy, Water, and Fuel Costs

May 25, 2014 by NRDC Switchboard

Summer Energy Savings

With Memorial Day fast approaching, it’s a good time to begin thinking about ways to save energy and water this summer in order to produce real, measurable benefits for you and the planet -- as well as help take stress off the power grid and prevent blackouts.[read more]

A New Way to Harness Waste Heat

Saving Waste Heat

Vast amounts of excess heat are generated by industrial processes and by electric power plants; researchers around the world have spent decades seeking ways to harness some of this wasted energy. Most such efforts have focused on thermoelectric devices.[read more]

10 US Cities Plan Coordinated Attack on Building Energy Waste

February 2, 2014 by Stephen Lacey

If building efficiency were an indicator of success in sports, we could likely declare a winner in this week's Super Bowl matchup between Seattle and Denver. As one of the top five most efficient cities in the country, Seattle takes the crown. But other cities aren't waiting on the sidelines.[read more]

Giant Gleaming Eggs Will Help Solve Urban Water, Energy and Waste Problems

January 3, 2014 by Tina Casey

Giant Eggs Solve Problems

Cities are takers: taking in energy and resources, while dumping out mountains of garbage and oceans of polluted wastewater. But take a look at the gigantic egg-shaped structures that dominate New York City’s Newtown Creek wastewater treatment plant, and you’re looking at a sustainable future.[read more]

Vampire Slaying and More: NRDC's Halloween Energy Survival Guide

October 30, 2013 by NRDC Switchboard

Along with being a fun holiday for tricks and treats, Halloween is an opportune time to shine a ghostly light on the evil energy vampires lurking in our homes. By these we mean those ghoulish fangs, also known as plugs in the wall, sucking frightening amounts of electricity all night (and day) long.[read more]
