Summer Cooling Costs

New energy-efficiency standards for room air conditioners went into effect June 1 – just in time to help save on summer AC bills. These standards will save Americans money this summer, and were set at levels agreed to jointly by efficiency advocates, manufacturers, and consumer groups.[read more]

World Air Conditioning Growth

America used to be the king of car sales, but China took that crown in 2009. America also used to be the world's biggest polluter, but China now has that dubious distinction as well. Now China could be set to surpass the U.S. in air conditioning use. By a lot.[read more]

Can We Curb Our Addiction to AC?

June 15, 2013 by Katherine Tweed

Chances are your power bill will be lower this summer than last summer. It’s not because of falling energy prices or eco-friendly practices, but because this year is expected to be cooler than 2012, which was much warmer than normal.[read more]

European Commission Holds Firm, Rejects Daimler's Push to Block New Climate-Friendly Refrigerant

December 21, 2012 by David Doniger

Good news today from Brussels, as the European Community holds firm and rejects last-minute pressure from by Daimler, maker of Mercedes-Benz, to block the introduction of a climate-friendly refrigerant in car air conditioners. As I’ve written here and here, the world auto industry is on the verge of a transition from HFC-134a, a powerful heat-trapping gas with 1,430 times the climate-changing power of carbon dioxide, to HFO-1234yf, a chemical with just 1/360th the punch.[read more]

Slowly but surely, the technology behind solar air conditioners is starting to improve, improving our chances of cutting the carbon footprint of cooling. Paolo Corrada, a PhD science and engineering student in at the Queensland University of Technology in Queensland, Australia has designed a solar air conditioning system that cuts electricity consumption by 90 percent...[read more]

How LED Lights Can Reduce Air Conditioning Costs This Summer

We all know that LED lights save energy, help the planet, reduce electrical costs, and last a whole lot longer than incandescent bulbs (the Cree LR6 Downlight LED, for example, is rated to last up to 50,000 hours -- somewhere between 25 and 50 times the lifespan of an incandescent bulb).  But they also have another benefit: they can...[read more]

VIDEO: Lost in the Ozone Again

So Andrew Dessler forwarded comments from Ted Parson on the history of the Montreal Protocol, in response to a point in the recent Nisbet opus.Parson's key claim (repeated here, on Deltoid, and recently on Grist) is:Yes, the claim that Montreal Protocol was easy because there was a substitute in hand is simply wrong, and the detailed...[read more]

Rooftop system uses solar to power a/c

August 22, 2009 by ToddWallace

Southern California Gas Company engineers are testing two rooftop systems that use solar power to chill water used for airconditioning. Sopogy’s and HelioDynamics’ systems are similar: Both use mirrors to aim the sun’s rays at water pipes, and when sun isn’t available to heat the water — at night, for example — both rely on gas as a...[read more]

Another Reason to forgo Air Conditioning: Sex

Cool. And Romantic. I have just learned that I am in excellent company.  My not-so subtle disdain for air-conditioning is probably not a lonely upshot of my up-bringing, but another happy element of my bond with the sisterhood.  As Washington Post reporter Steve Hendrix put it this his piece, A/C Setting can push couples to...[read more]

Living Without AC: Ideas The New York Times Left Out.

July 24, 2009 by Peter Troast

Really - you don't need it! (source: roomairconditioners.us) Wednesday, the New York Times published a piece entitled, “The Unchilled Life: Breezing Through the Recession Without Air-Conditioning,” touting the benefits of life without air conditioning.  The majority of those interviewed found their (often recent) conversion to...[read more]

The South is Different

Matt’s pretty much the best blogger out there, but this isn’t quite right: This is, of course, but a small slice of the larger southern politics tradition which has always insisted since the end of the Civil War that cheap labor and a low-tax, low-service, high-inequality social and economic system are the key to prosperity. This...[read more]
