Your air conditioner is making the heat wave worse – chicago tribune

How did this happen? The technology was slow to take off: In 1960, 12 percent of U.S. Gas density households had air conditioning; by 1980, that had risen to just 55 percent; now it’s almost 90 percent. Types of electricity But once cooling technology became more efficient and affordable after World War II, it began transforming the architecture of cities and suburbs, as the historian Gail Cooper shows in her book “Air-Conditioning America.” It ushered in the glass office-block design with deep, cheap-to-build interior spaces that never could have been comfortable in the summer without artificial cooling. Electricity merit badge pamphlet pdf House and apartment builders could dispense with expensive warm-weather features such as porches, large eaves, high ceilings, cross-ventilated designs, transom windows, windows that open and attic fans. Electricity jeopardy That made homes more widely affordable, but buyers usually ended up living in what Fortune magazine called a “TV-equipped hotbox” that was livable in the summer only with air conditioning.

With prosperity (and summer temperatures) increasing through the 1990s, builders and home buyers could have gone back to investing in warm-weather architectural features, but instead they opted to spend their money on more floor space. Electricity static electricity By 2006, the average new house had three times the square footage per occupant that it had in 1950, increasing from about 290 square feet per family member to nearly 900 square feet each. Gas density units Cooling demand soared accordingly: Between 1993 and 2005, when the increase in house size was reaching its zenith, total consumption of electricity for residential air conditioning nearly doubled, from 134 billion kilowatt-hours to 261 billion, according to U.S. Electricity explained Energy Information Administration surveys. Electricity png The Energy Department says air conditioners use about 5 percent of all the electricity produced in the country each year, costing homeowners more than $11 billion.

It’s not too late to reduce our dependence on air conditioning, especially in rural areas, small towns and leafy suburbs. Static electricity sound effect Even in big cities, homeowners can plant shade trees and other vegetation, install whole-house fans, sleep in the basement. Hp gas kushaiguda On the other hand, apartment dwellers have far fewer options: They can live with open windows, fans and cold showers up to a point, but when heat waves arrive, it’s time to reach for the thermostat.

Economically distressed urban neighborhoods face more than just discomfort. Gas natural Decades of research demonstrates that heat-wave mortality is highest in concrete-and-asphalt urban disasterscapes, especially among elderly or ill people who are socially isolated, living behind closed windows for fear of crime (a factor in the 1995 Chicago heat wave, which killed more than 700 people) or unable to afford the electricity required to run an air conditioner or even a fan. Gas what i smoke There, community cooling centers become refuges of last resort.

Air conditioning has become a necessity but not a solution. La gas prices It’s like an ice bath for a patient suffering an extreme fever, treating the symptom while leaving untouched the underlying cause — in this case, the one-two punch of climate change and the distorted physical and social structure of our cities. Gas in back And by making our world temporarily cooler, air conditioning is making it permanently hotter, thanks to the increases in greenhouse gas emissions from power plants, vehicle fuel consumption and refrigerant production that keep the cool air flowing.

I calculate, based on figures from the Energy Information Administration and the Environmental Protection Agency, that the air conditioning of America has a climate impact equivalent to 500 million tons of carbon dioxide — more than all industrial processes combined. Dynamic electricity examples About three-fourths of the impact is from generating the electricity to cool buildings, and the rest is split evenly between excess fuel consumption by air-conditioned vehicles and leakage of refrigerants used by all air conditioners.

So as temperatures rise, it’s a good time to question the prevailing assumption that adapting to more frequent heat waves in the future will simply mean using even more air conditioning. Gas 78 industries That will be an exercise in tail-chasing. I feel electricity in my body It will do nothing for the millions of people who work outdoors or in the many industrial plants that are well out of air conditioning’s reach. Gas after eating dairy Global warming will take an especially harsh toll on them.

Climate adaptation can work only if it’s linked to stopping global climate disruption, and both require us to start digging up root causes. Electricity pictures information Acute problems should have priority. Electricity lesson plans for 5th grade We must help the most distressed urban hot zones cool down again by jackhammering concrete, re-creating green space and improving the quality of housing. Gas bloating pregnancy All that would help fight the “urban heat island” effect, which can make cities as much as 22 degrees Fahrenheit warmer than their surrounding areas.

Reducing air conditioning dependence in urban areas will require a serious overhaul: things like steadily shrinking parking and driving space, accompanied by improvements in public transportation; depaving and revegetating the rescued space; retrofitting large buildings with ventilation shafts to allow air in when weather permits; and mandating that all new construction be designed for non-air-conditioned comfort at times of the year when it’s achievable, with features such as windows that can open, better air-flow within buildings and building shapes that give everyone an external window. C gastronomie limonest For significant parts of the year in much of the country, air conditioning systems are running to keep temperatures at 70 or 72 when the outside temperature is, say, 85. Gas 99 cents With better ventilation and building design and a tolerance for only slightly higher temperatures indoors, we wouldn’t need artificial cooling.

According to analysts at the Lawrence Berkeley National Laboratory, a crash program to maintain or establish three shade trees per building and make all roofs and pavement in U.S. Gas x strips ingredients cities reflective could decrease cooling demand by a whopping 20 percent by driving temperatures lower. 66 gas station That would directly reduce electricity and vehicle fuel consumption, and it would also increase the number of days per year when air conditioning could safely be switched off by making buildings more comfortable without artificial climate control.
