LED Christmas lights can save energy and aggravation

November 20th, 2012

Those old-style incandescent lights? They’re still around, certainly. But more and more, they’re being crowded out by the new kids on the illumination block: The longer-lasting, more energy-efficient Light Emitting Diode (LED) option.
LEDs have been around for a few years now, and they’ve got quite a bit going for them. Promotional materials tout energy savings of 80 percent or more over their incandescent brethren.

Five hopeful signs that we could save our planet if we really want to

August 1st, 2012

Other than the 2012 Olympics, it’s been a discouraging hot, drought-y month this July. Greenland ice sheets are melting ominously. India plunged into darkness and panic amid two days of massive electrical outages. Cargill recalled about 15 tons of tainted hamburger in the Mid-Atlantic and the New England states. And there are disheartening reports about crop failures in the mighty U.S. “bread basket”.

Addressing climate change would save money

May 2nd, 2012

The media seems intent on giving climate skeptics much more than equal time. On Monday, the New York Times printed a cover story about the last arrow in the climate skeptics arsenal, the argument that cloud cover will adjust to a warming world and let more heat escape to space.

Battle of the Buildings pits offices, schools and skyscrapers in contest to cut energy use

May 25th, 2011

Building new green buildings can be exciting. But taking old buildings, like a giant college dormitory built in 1965, and making them as energy efficient as they can be, there’s real satisfaction in that, too.

Morrison Hall at UNC won last year's Battle of the Buildings.


And dollar savings.

Push back progress on light bulbs? Not a bright idea

March 11th, 2011

Rep. Joe Barton’s last bright idea – to apologize to BP for having to make reparations for the oil spill in the Gulf of Mexico – earned him national ridicule.

His pandering may not have misfired (much) in the conservative-leaning Texas district he represents, but it was a rude affront to those who earn a living on the gulf, and anyone who cares about the workers and wildlife there.

U.S. Rep. Joe Barton

Now, less than a year later, Barton again appears to have his finger on the pulse of the mean-spirited minority.

Introduction to LEDs: What you need to know

October 4th, 2010

This LED uses just 6 watts.

As with other technologies, advances in lighting just keep coming. Now that you’re somewhat comfortable with CFL — compact fluorescent lamp — bulbs, get ready for things to change again. The latest generation of LEDs — light-emitting diodes — are here and manufacturers claim they rival the look, dimming ability, and light quality of incandescents. Better yet, LEDs contain no mercury, and last up to five times longer than CFLs and 50 times longer than incandescents. They are pricey, many sell for $60 or more, but could save about $300 in electrical cost over its life compared with an incandescent.

Get your ducts in a row

June 24th, 2010

You can hear them rattle in the winter, and rumble in the summer. Whether they’re underfoot or overhead in the attic, these unseen monsters can really make a difference in your home’s heating and cooling bills. Yes, we’re talking about your ducts or duct work, and we don’t mean to be personal when we say, you’d better have your ducts in order when it comes to saving on cooling costs.

Be part of the solution: Chipping away at coal

April 19th, 2010

Sitting in a heap atop the list of climate offenders is coal. Coal-burning power plants are the single biggest source of carbon emissions worldwide and their smokestacks spew sulfur and nitrogen dioxide, as well, contributing to the stew of greenhouse gases that are heating the Earth’s atmosphere.

Despite the growth of renewable energy sources, coal remains the single largest provider of energy for America, at 45 percent. And its toxic footprint doesn’t end with air pollution. The industry’s waste, leftover ash, is laced with metal oxides.

Steven Chu: Making buildings energy efficient ‘is truly low hanging fruit’

March 22nd, 2010

(In this piece, reprinted from a collection of essays assembled by the World Economic Forum, a Switzerland-based non-profit commited to improving the state of the world, U.S. Secretary of Energy argues that making buildings energy efficient can rack up substantial energy savings. Chu also discusses why businesses and individuals have previously failed to pick up on this opportunity.)

Steven Chu, U.S. Secretary of Energy

For the next few decades, energy efficiency is one of the lowest cost options for reducing US carbon emissions. Many studies have concluded that energy efficiency can save both energy and money. For example, a recent McKinsey report calculated the potential savings assuming a 7% discount rate, no price on carbon and using only “net present value positive” investments. It found the potential to reduce consumer demand by about 23% by 2020 and reduce GHG emissions by 1.1 gigatons each year — at a net savings of US$ 680 billion.
