Expert Interview: Increase in Demand for Air Conditioning, Growth for Industry Likely in India

November 4, 2015 by NRDC Switchboard

India AC Needs

HFCs are one of the six greenhouse gases and very potent contributors to global warming, most prominently being used in the room and mobile air conditioning sectors worldwide. How will HFCs play into climate change risk when India's large population is beginning to need AC on a large scale?[read more]

India Likely to Experience Continued Growth in Electricity Use for Air Conditioning

October 30, 2015 by U.S. EIA: Today in Energy

India and AC Needs

Energy demand for space cooling is growing rapidly in India and around the world, driven by rising incomes and a natural preference for certain ambient air temperatures. Currently, India has a relatively low penetration of air conditioning, while the United States is a much more saturated market.[read more]

Are We Over-Air Conditioned?

September 9, 2015 by Meredith Fowlie

Air Conditioning and Energy Use

Air conditioning made lots of headlines this summer. In newspaper accounts, internet memes, and office gripe sessions, there was much commiseration about the over-air conditioning of the American workplace. Is it actually true? And what can we do to reduce workplace energy waste?[read more]

India Energy Consumption Efficiency

India leapfrogging over antiquated, soon-to-be obsolete, and inefficient refrigerants will benefit the power sector while saving consumers money. It will also advance the Indian economy, ensure Indian industries can compete in the international market, and help mitigate climate change.[read more]

DIY Friday: Five Ways to Cut Your Air Conditioning Costs

August 8, 2014 by Sarah Battaglia

Do you hear something? It’s like a muffled whooshing sound. You should be able to hear the sound of your air conditioner sucking up all of your cash. The cost to run an air conditioning unit is getting expensive, and you may have even tried surviving with no cool air.[read more]

As Summer Heats Up, New Room AC Standards Will Help Cut Cooling Costs

June 2, 2014 by NRDC Switchboard

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]

Global AC Needs Could Grow 50 Times Greater Than US Demand

August 24, 2013 by Stephen Lacey

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

May 17, 2011 by Peter Troast

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]

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]
